6 | |
7 This subject is introduced in section |30.1| of the user manual. | |
8 | |
9 1. Using QuickFix commands |quickfix| | |
10 2. The error window |quickfix-window| | |
11 3. Using more than one list of errors |quickfix-error-lists| | |
12 4. Using :make |:make_makeprg| | |
13 5. Using :grep |grep| | |
14 6. Selecting a compiler |compiler-select| | |
15 7. The error format |error-file-format| | |
16 8. The directory stack |quickfix-directory-stack| | |
17 9. Specific error file formats |errorformats| | |
18 | |
19 {Vi does not have any of these commands} | |
20 | |
21 The quickfix commands are not available when the |+quickfix| feature was | |
22 disabled at compile time. | |
23 | |
24 ============================================================================= | |
25 1. Using QuickFix commands *quickfix* *Quickfix* *E42* | |
26 | |
27 Vim has a special mode to speedup the edit-compile-edit cycle. This is | |
28 inspired by the quickfix option of the Manx's Aztec C compiler on the Amiga. | |
29 The idea is to save the error messages from the compiler in a file and use Vim | |
30 to jump to the errors one by one. You can examine each problem and fix it, | |
31 without having to remember all the error messages. | |
32 | |
170 | 33 In Vim the quickfix commands are used more generally to find a list of |
34 positions in files. For example, |:vimgrep| finds pattern matches. You can | |
231 | 35 use the positions in a script with the |getqflist()| function. Thus you can |
170 | 36 do a lot more than the edit/compile/fix cycle! |

644 | 54 *location-list* *E776* |
11160 | 55 A location list is a window-local quickfix list. You get one after commands |
56 like `:lvimgrep`, `:lgrep`, `:lhelpgrep`, `:lmake`, etc., which create a | |
57 location list instead of a quickfix list as the corresponding `:vimgrep`, | |
58 `:grep`, `:helpgrep`, `:make` do. | |
59 A location list is associated with a window and each window can have a | |
60 separate location list. A location list can be associated with only one | |
61 window. The location list is independent of the quickfix list. | |
644 | 62 |
648 | 63 When a window with a location list is split, the new window gets a copy of the |

91 has been changed, there is the only window for the | |
92 buffer and both 'hidden' and 'autowrite' are off. | |

1624 | 174 WARNING: All changes in files are lost! Also when the |
175 [!] is not used. It works like ":qall!" |:qall|, | |

178 *:cf* *:cfile* | |
179 :cf[ile][!] [errorfile] Read the error file and jump to the first error. | |
180 This is done automatically when Vim is started with | |
181 the -q option. You can use this command when you | |
182 keep Vim running while compiling. If you give the | |
183 name of the errorfile, the 'errorfile' option will | |
184 be set to [errorfile]. See |:cc| for [!]. | |

7 | 525 Normally the quickfix window is at the bottom of the screen. If there are |
526 vertical splits, it's at the bottom of the rightmost column of windows. To | |
527 make it always occupy the full width: > | |
528 :botright cwindow | |
529 You can move the window around with |window-moving| commands. | |
530 For example, to move it to the top: CTRL-W K | |
531 The 'winfixheight' option will be set, which means that the window will mostly | |
532 keep its height, ignoring 'winheight' and 'equalalways'. You can change the | |
533 height manually (e.g., by dragging the status line above it with the mouse). | |
534 | |
535 In the quickfix window, each line is one error. The line number is equal to | |

540 You can use ":.cc" to jump to the error under the cursor. |
170 | 541 Hitting the <Enter> key or double-clicking the mouse on a line has the same |
7 | 542 effect. The file containing the error is opened in the window above the |
543 quickfix window. If there already is a window for that file, it is used | |
544 instead. If the buffer in the used window has changed, and the error is in | |
545 another file, jumping to the error will fail. You will first have to make | |
546 sure the window contains a buffer which can be abandoned. | |
170 | 547 *CTRL-W_<Enter>* *CTRL-W_<CR>* |
548 You can use CTRL-W <Enter> to open a new window and jump to the error there. | |
7 | 549 |
550 When the quickfix window has been filled, two autocommand events are | |
551 triggered. First the 'filetype' option is set to "qf", which triggers the | |
651 | 552 FileType event. Then the BufReadPost event is triggered, using "quickfix" for |
553 the buffer name. This can be used to perform some action on the listed | |
554 errors. Example: > | |
648 | 555 au BufReadPost quickfix setlocal modifiable |
556 \ | silent exe 'g/^/s//\=line(".")." "/' | |
557 \ | setlocal nomodifiable | |
7 | 558 This prepends the line number to each line. Note the use of "\=" in the |
559 substitute string of the ":s" command, which is used to evaluate an | |
560 expression. | |
651 | 561 The BufWinEnter event is also triggered, again using "quickfix" for the buffer |
562 name. | |

7 | 567 Note: Making changes in the quickfix window has no effect on the list of |
568 errors. 'modifiable' is off to avoid making changes. If you delete or insert | |
569 lines anyway, the relation between the text and the error number is messed up. | |
570 If you really want to do this, you could write the contents of the quickfix | |
571 window to a file and use ":cfile" to have it parsed and used as the new error | |
572 list. | |
573 | |
644 | 574 *location-list-window* |
648 | 575 The location list window displays the entries in a location list. When you |
576 open a location list window, it is created below the current window and | |
577 displays the location list for the current window. The location list window | |
578 is similar to the quickfix window, except that you can have more than one | |
651 | 579 location list window open at a time. When you use a location list command in |
580 this window, the displayed location list is used. | |
648 | 581 |
582 When you select a file from the location list window, the following steps are | |
583 used to find a window to edit the file: | |
644 | 584 |
648 | 585 1. If a window with the location list displayed in the location list window is |
586 present, then the file is opened in that window. | |
587 2. If the above step fails and if the file is already opened in another | |
588 window, then that window is used. | |
589 3. If the above step fails then an existing window showing a buffer with | |
590 'buftype' not set is used. | |
591 4. If the above step fails, then the file is edited in a new window. | |
592 | |
593 In all of the above cases, if the location list for the selected window is not | |
594 yet set, then it is set to the location list displayed in the location list | |
595 window. | |

709 3. Using more than one list of errors *quickfix-error-lists* | |
710 | |
711 So far has been assumed that there is only one list of errors. Actually the | |
712 ten last used lists are remembered. When starting a new list, the previous | |
713 ones are automatically kept. Two commands can be used to access older error | |
714 lists. They set one of the existing error lists as the current one. | |
715 | |
716 *:colder* *:col* *E380* | |
717 :col[der] [count] Go to older error list. When [count] is given, do | |
718 this [count] times. When already at the oldest error | |
719 list, an error message is given. | |

7 | 745 When adding a new error list, it becomes the current list. |
746 | |
747 When ":colder" has been used and ":make" or ":grep" is used to add a new error | |
748 list, one newer list is overwritten. This is especially useful if you are | |
749 browsing with ":grep" |grep|. If you want to keep the more recent error | |
750 lists, use ":cnewer 99" first. | |

795 This is done by passing the command to the shell given with the 'shell' | |
796 option. This works almost like typing | |
797 | |
798 ":!{makeprg} [arguments] {shellpipe} {errorfile}". | |
799 | |
800 {makeprg} is the string given with the 'makeprg' option. Any command can be | |
801 used, not just "make". Characters '%' and '#' are expanded as usual on a | |
802 command-line. You can use "%<" to insert the current file name without | |
803 extension, or "#<" to insert the alternate file name without extension, for | |
804 example: > | |
805 :set makeprg=make\ #<.o | |
806 | |
807 [arguments] is anything that is typed after ":make". | |
808 {shellpipe} is the 'shellpipe' option. | |
809 {errorfile} is the 'makeef' option, with ## replaced to make it unique. | |
810 | |
2072 | 811 The placeholder "$*" can be used for the argument list in {makeprg} if the |
7 | 812 command needs some additional characters after its arguments. The $* is |
813 replaced then by all arguments. Example: > | |
814 :set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*} | |
815 or simpler > | |
816 :let &mp = 'latex \\nonstopmode \\input\{$*}' | |
817 "$*" can be given multiple times, for example: > | |
818 :set makeprg=gcc\ -o\ $*\ $* | |
819 | |
820 The 'shellpipe' option defaults to ">" for the Amiga, MS-DOS and Win32. This | |
821 means that the output of the compiler is saved in a file and not shown on the | |
822 screen directly. For Unix "| tee" is used. The compiler output is shown on | |
823 the screen and saved in a file the same time. Depending on the shell used | |
824 "|& tee" or "2>&1| tee" is the default, so stderr output will be included. | |
825 | |
826 If 'shellpipe' is empty, the {errorfile} part will be omitted. This is useful | |
827 for compilers that write to an errorfile themselves (e.g., Manx's Amiga C). | |
828 | |

830 Using QuickFixCmdPost to fix the encoding ~ | |
831 | |
832 It may be that 'encoding' is set to an encoding that differs from the messages | |
833 your build program produces. This example shows how to fix this after Vim has | |
834 read the error messages: > | |
835 | |
836 function QfMakeConv() | |
837 let qflist = getqflist() | |
838 for i in qflist | |
839 let i.text = iconv(i.text, "cp936", "utf-8") | |
840 endfor | |
841 call setqflist(qflist) | |
842 endfunction | |
843 | |
844 au QuickfixCmdPost make call QfMakeConv() | |

41 | 850 5. Using :vimgrep and :grep *grep* *lid* |
851 | |
852 Vim has two ways to find matches for a pattern: Internal and external. The | |
853 advantage of the internal grep is that it works on all systems and uses the | |
854 powerful Vim search patterns. An external grep program can be used when the | |
855 Vim grep does not do what you want. | |
856 | |
43 | 857 The internal method will be slower, because files are read into memory. The |
858 advantages are: | |
859 - Line separators and encoding are automatically recognized, as if a file is | |
860 being edited. | |
861 - Uses Vim search patterns. Multi-line patterns can be used. | |
862 - When plugins are enabled: compressed and remote files can be searched. | |
863 |gzip| |netrw| | |
717 | 864 |
865 To be able to do this Vim loads each file as if it is being edited. When | |
720 | 866 there is no match in the file the associated buffer is wiped out again. The |
717 | 867 'hidden' option is ignored here to avoid running out of memory or file |
868 descriptors when searching many files. However, when the |:hide| command | |
869 modifier is used the buffers are kept loaded. This makes following searches | |
870 in the same files a lot faster. | |

881 5.1 using Vim's internal grep | |
882 | |
86 | 883 *:vim* *:vimgrep* *E682* *E683* |
170 | 884 :vim[grep][!] /{pattern}/[g][j] {file} ... |
41 | 885 Search for {pattern} in the files {file} ... and set |
3682 | 886 the error list to the matches. Files matching |
887 'wildignore' are ignored; files in 'suffixes' are | |
888 searched last. | |
170 | 889 Without the 'g' flag each line is added only once. |
890 With 'g' every match is added. | |
891 | |
892 {pattern} is a Vim search pattern. Instead of | |
893 enclosing it in / any non-ID character (see | |
894 |'isident'|) can be used, so long as it does not | |
895 appear in {pattern}. | |
896 'ignorecase' applies. To overrule it put |/\c| in the | |
897 pattern to ignore case or |/\C| to match case. | |
898 'smartcase' is not used. | |
4197 | 899 If {pattern} is empty (e.g. // is specified), the last |
900 used search pattern is used. |last-pattern| | |
170 | 901 |
716 | 902 When a number is put before the command this is used |
903 as the maximum number of matches to find. Use | |
904 ":1vimgrep pattern file" to find only the first. | |
905 Useful if you only want to check if there is a match | |
906 and quit quickly when it's found. | |
907 | |
170 | 908 Without the 'j' flag Vim jumps to the first match. |
909 With 'j' only the quickfix list is updated. | |
910 With the [!] any changes in the current buffer are | |
911 abandoned. | |
912 | |
123 | 913 Every second or so the searched file name is displayed |
914 to give you an idea of the progress made. | |
43 | 915 Examples: > |
916 :vimgrep /an error/ *.c | |
917 :vimgrep /\<FileName\>/ *.h include/* | |
445 | 918 :vimgrep /myfunc/ **/*.c |
919 < For the use of "**" see |starstar-wildcard|. | |
41 | 920 |
43 | 921 :vim[grep][!] {pattern} {file} ... |
922 Like above, but instead of enclosing the pattern in a | |
923 non-ID character use a white-separated pattern. The | |
924 pattern must start with an ID character. | |
925 Example: > | |
926 :vimgrep Error *.c | |
927 < | |
658 | 928 *:lv* *:lvimgrep* |
929 :lv[imgrep][!] /{pattern}/[g][j] {file} ... | |
930 :lv[imgrep][!] {pattern} {file} ... | |
931 Same as ":vimgrep", except the location list for the | |
932 current window is used instead of the quickfix list. | |
933 | |
41 | 934 *:vimgrepa* *:vimgrepadd* |
170 | 935 :vimgrepa[dd][!] /{pattern}/[g][j] {file} ... |
936 :vimgrepa[dd][!] {pattern} {file} ... | |
41 | 937 Just like ":vimgrep", but instead of making a new list |
938 of errors the matches are appended to the current | |
939 list. | |
940 | |
658 | 941 *:lvimgrepa* *:lvimgrepadd* |
942 :lvimgrepa[dd][!] /{pattern}/[g][j] {file} ... | |
943 :lvimgrepa[dd][!] {pattern} {file} ... | |
944 Same as ":vimgrepadd", except the location list for | |
945 the current window is used instead of the quickfix | |
946 list. | |
41 | 947 |
948 5.2 External grep | |
7 | 949 |
950 Vim can interface with "grep" and grep-like programs (such as the GNU | |
951 id-utils) in a similar way to its compiler integration (see |:make| above). | |
952 | |
953 [Unix trivia: The name for the Unix "grep" command comes from ":g/re/p", where | |
954 "re" stands for Regular Expression.] | |
955 | |
956 *:gr* *:grep* | |
957 :gr[ep][!] [arguments] Just like ":make", but use 'grepprg' instead of | |
958 'makeprg' and 'grepformat' instead of 'errorformat'. | |
41 | 959 When 'grepprg' is "internal" this works like |
960 |:vimgrep|. Note that the pattern needs to be | |
961 enclosed in separator characters then. | |

997 | |
41 | 998 5.3 Setting up external grep |
7 | 999 |
1000 If you have a standard "grep" program installed, the :grep command may work | |
237 | 1001 well with the defaults. The syntax is very similar to the standard command: > |
7 | 1002 |
1003 :grep foo *.c | |
1004 | |
237 | 1005 Will search all files with the .c extension for the substring "foo". The |
7 | 1006 arguments to :grep are passed straight to the "grep" program, so you can use |
1007 whatever options your "grep" supports. | |
1008 | |
1009 By default, :grep invokes grep with the -n option (show file and line | |
237 | 1010 numbers). You can change this with the 'grepprg' option. You will need to set |
7 | 1011 'grepprg' if: |
1012 | |
1013 a) You are using a program that isn't called "grep" | |
1014 b) You have to call grep with a full path | |
1015 c) You want to pass other options automatically (e.g. case insensitive | |
1016 search.) | |
1017 | |
1018 Once "grep" has executed, Vim parses the results using the 'grepformat' | |
1019 option. This option works in the same way as the 'errorformat' option - see | |
1020 that for details. You may need to change 'grepformat' from the default if | |
1021 your grep outputs in a non-standard format, or you are using some other | |
1022 program with a special format. | |
1023 | |
1024 Once the results are parsed, Vim loads the first file containing a match and | |
1025 jumps to the appropriate line, in the same way that it jumps to a compiler | |
1026 error in |quickfix| mode. You can then use the |:cnext|, |:clist|, etc. | |
1027 commands to see the other matches. | |
1028 | |
1029 | |
41 | 1030 5.4 Using :grep with id-utils |
7 | 1031 |
1032 You can set up :grep to work with the GNU id-utils like this: > | |
1033 | |
1034 :set grepprg=lid\ -Rgrep\ -s | |
1035 :set grepformat=%f:%l:%m | |
1036 | |
1037 then > | |
1038 :grep (regexp) | |
1039 | |
1040 works just as you'd expect. | |
1041 (provided you remembered to mkid first :) | |
1042 | |
1043 | |
41 | 1044 5.5 Browsing source code with :vimgrep or :grep |
7 | 1045 |
1046 Using the stack of error lists that Vim keeps, you can browse your files to | |
1047 look for functions and the functions they call. For example, suppose that you | |
1048 have to add an argument to the read_file() function. You enter this command: > | |
1049 | |
41 | 1050 :vimgrep /\<read_file\>/ *.c |
7 | 1051 |
1052 You use ":cn" to go along the list of matches and add the argument. At one | |
1053 place you have to get the new argument from a higher level function msg(), and | |
1054 need to change that one too. Thus you use: > | |
1055 | |
41 | 1056 :vimgrep /\<msg\>/ *.c |
7 | 1057 |
1058 While changing the msg() functions, you find another function that needs to | |
41 | 1059 get the argument from a higher level. You can again use ":vimgrep" to find |
1060 these functions. Once you are finished with one function, you can use > | |
7 | 1061 |
1062 :colder | |
1063 | |
1064 to go back to the previous one. | |
1065 | |
41 | 1066 This works like browsing a tree: ":vimgrep" goes one level deeper, creating a |
7 | 1067 list of branches. ":colder" goes back to the previous level. You can mix |
41 | 1068 this use of ":vimgrep" and "colder" to browse all the locations in a tree-like |
7 | 1069 way. If you do this consistently, you will find all locations without the |
1070 need to write down a "todo" list. | |

1090 *current_compiler* | |
1091 To support older Vim versions, the plugins always use "current_compiler" and | |
1092 not "b:current_compiler". What the command actually does is the following: | |
1093 | |
1094 - Delete the "current_compiler" and "b:current_compiler" variables. | |
1095 - Define the "CompilerSet" user command. With "!" it does ":set", without "!" | |
1096 it does ":setlocal". | |
1097 - Execute ":runtime! compiler/{name}.vim". The plugins are expected to set | |
1098 options with "CompilerSet" and set the "current_compiler" variable to the | |
1099 name of the compiler. | |
170 | 1100 - Delete the "CompilerSet" user command. |
7 | 1101 - Set "b:current_compiler" to the value of "current_compiler". |
1102 - Without "!" the old value of "current_compiler" is restored. | |

1109 | |
1110 There's one variable you can set for the GCC compiler: | |

1113 Ignore lines that don't match any patterns | |
1114 defined for GCC. Useful if output from | |

7 | 1119 MANX AZTEC C *quickfix-manx* *compiler-manx* |
1120 | |
1121 To use Vim with Manx's Aztec C compiler on the Amiga you should do the | |
1122 following: | |
1123 - Set the CCEDIT environment variable with the command: > | |
1124 mset "CCEDIT=vim -q" | |
1125 - Compile with the -qf option. If the compiler finds any errors, Vim is | |
1126 started and the cursor is positioned on the first error. The error message | |
1127 will be displayed on the last line. You can go to other errors with the | |
1128 commands mentioned above. You can fix the errors and write the file(s). | |
1129 - If you exit Vim normally the compiler will re-compile the same file. If you | |
1130 exit with the :cq command, the compiler will terminate. Do this if you | |
1131 cannot fix the error, or if another file needs to be compiled first. | |
1132 | |
1133 There are some restrictions to the Quickfix mode on the Amiga. The | |
1134 compiler only writes the first 25 errors to the errorfile (Manx's | |
1135 documentation does not say how to get more). If you want to find the others, | |
1136 you will have to fix a few errors and exit the editor. After recompiling, | |
1137 up to 25 remaining errors will be found. | |
1138 | |
1139 If Vim was started from the compiler, the :sh and some :! commands will not | |
1140 work, because Vim is then running in the same process as the compiler and | |
1141 stdin (standard input) will not be interactive. | |

1147 syntax checking feature and parses the output for possible errors so you can | |
1148 correct them in quick-fix mode. | |
1149 | |
1150 Warnings are forced regardless of "no warnings" or "$^W = 0" within the file | |
1151 being checked. To disable this set g:perl_compiler_force_warnings to a zero | |
1152 value. For example: > | |
1153 let g:perl_compiler_force_warnings = 0 | |
1154 | |
1155 | |
7 | 1156 PYUNIT COMPILER *compiler-pyunit* |
1157 | |
1158 This is not actually a compiler, but a unit testing framework for the | |
237 | 1159 Python language. It is included into standard Python distribution |
1160 starting from version 2.0. For older versions, you can get it from | |
7 | 1161 http://pyunit.sourceforge.net. |
1162 | |
1163 When you run your tests with the help of the framework, possible errors | |
1164 are parsed by Vim and presented for you in quick-fix mode. | |
1165 | |
1166 Unfortunately, there is no standard way to run the tests. | |
1167 The alltests.py script seems to be used quite often, that's all. | |
1168 Useful values for the 'makeprg' options therefore are: | |
1169 setlocal makeprg=./alltests.py " Run a testsuite | |
5690 | 1170 setlocal makeprg=python\ %:S " Run a single testcase |
7 | 1171 |
1172 Also see http://vim.sourceforge.net/tip_view.php?tip_id=280. | |
1173 | |
1174 | |
1175 TEX COMPILER *compiler-tex* | |
1176 | |
1177 Included in the distribution compiler for TeX ($VIMRUNTIME/compiler/tex.vim) | |
237 | 1178 uses make command if possible. If the compiler finds a file named "Makefile" |
7 | 1179 or "makefile" in the current directory, it supposes that you want to process |
237 | 1180 your *TeX files with make, and the makefile does the right work. In this case |
1181 compiler sets 'errorformat' for *TeX output and leaves 'makeprg' untouched. If | |
7 | 1182 neither "Makefile" nor "makefile" is found, the compiler will not use make. |
1183 You can force the compiler to ignore makefiles by defining | |
1184 b:tex_ignore_makefile or g:tex_ignore_makefile variable (they are checked for | |
1185 existence only). | |
1186 | |
1187 If the compiler chose not to use make, it need to choose a right program for | |
237 | 1188 processing your input. If b:tex_flavor or g:tex_flavor (in this precedence) |
7 | 1189 variable exists, it defines TeX flavor for :make (actually, this is the name |
1190 of executed command), and if both variables do not exist, it defaults to | |
237 | 1191 "latex". For example, while editing chapter2.tex \input-ed from mypaper.tex |
7 | 1192 written in AMS-TeX: > |
1193 | |
1194 :let b:tex_flavor = 'amstex' | |
1195 :compiler tex | |
1196 < [editing...] > | |
1197 :make mypaper | |
1198 | |
1199 Note that you must specify a name of the file to process as an argument (to | |
1200 process the right file when editing \input-ed or \include-ed file; portable | |
237 | 1201 solution for substituting % for no arguments is welcome). This is not in the |
7 | 1202 semantics of make, where you specify a target, not source, but you may specify |
1203 filename without extension ".tex" and mean this as "make filename.dvi or | |
1204 filename.pdf or filename.some_result_extension according to compiler". | |
1205 | |
1206 Note: tex command line syntax is set to usable both for MikTeX (suggestion | |
237 | 1207 by Srinath Avadhanula) and teTeX (checked by Artem Chuprina). Suggestion |
7 | 1208 from |errorformat-LaTeX| is too complex to keep it working for different |
1209 shells and OSes and also does not allow to use other available TeX options, | |
237 | 1210 if any. If your TeX doesn't support "-interaction=nonstopmode", please |
7 | 1211 report it with different means to express \nonstopmode from the command line. |
1212 | |
1213 ============================================================================= | |
1214 7. The error format *error-file-format* | |
1215 | |
1216 *errorformat* *E372* *E373* *E374* | |
1217 *E375* *E376* *E377* *E378* | |
1218 The 'errorformat' option specifies a list of formats that are recognized. The | |
1219 first format that matches with an error message is used. You can add several | |
1220 formats for different messages your compiler produces, or even entries for | |
1221 multiple compilers. See |efm-entries|. | |
1222 | |
1223 Each entry in 'errorformat' is a scanf-like string that describes the format. | |
1224 First, you need to know how scanf works. Look in the documentation of your | |
1225 C compiler. Below you find the % items that Vim understands. Others are | |
1226 invalid. | |
1227 | |
1228 Special characters in 'errorformat' are comma and backslash. See | |
1229 |efm-entries| for how to deal with them. Note that a literal "%" is matched | |
1230 by "%%", thus it is not escaped with a backslash. | |
5277 | 1231 Keep in mind that in the `:make` and `:grep` output all NUL characters are |
1232 replaced with SOH (0x01). | |
7 | 1233 |
1234 Note: By default the difference between upper and lowercase is ignored. If | |
1235 you want to match case, add "\C" to the pattern |/\C|. | |
1236 | |
1237 | |
1238 Basic items | |
1239 | |

1243 %c column number (finds a number representing character | |
1244 column of the error, (1 <tab> == 1 character column)) | |

237 | 1247 columns)) |
7 | 1248 %t error type (finds a single character) |
1249 %n error number (finds a number) | |
1250 %m error message (finds a string) | |
1251 %r matches the "rest" of a single-line file message %O/P/Q | |
3557 | 1252 %p pointer line (finds a sequence of '-', '.', ' ' or |
1253 tabs and uses the length for the column number) | |
7 | 1254 %*{conv} any scanf non-assignable conversion |
1255 %% the single '%' character | |
231 | 1256 %s search text (finds a string) |
7 | 1257 |
502 | 1258 The "%f" conversion may depend on the current 'isfname' setting. "~/" is |
279 | 1259 expanded to the home directory and environment variables are expanded. |
7 | 1260 |
502 | 1261 The "%f" and "%m" conversions have to detect the end of the string. This |
534 | 1262 normally happens by matching following characters and items. When nothing is |
502 | 1263 following the rest of the line is matched. If "%f" is followed by a '%' or a |
1264 backslash, it will look for a sequence of 'isfname' characters. | |
7 | 1265 |
1266 On MS-DOS, MS-Windows and OS/2 a leading "C:" will be included in "%f", even | |
1267 when using "%f:". This means that a file name which is a single alphabetical | |
1268 letter will not be detected. | |
1269 | |
1270 The "%p" conversion is normally followed by a "^". It's used for compilers | |
1271 that output a line like: > | |
1272 ^ | |
1273 or > | |
1274 ---------^ | |
1275 to indicate the column of the error. This is to be used in a multi-line error | |
1276 message. See |errorformat-javac| for a useful example. | |
1277 | |
13857 | 1278 The "%s" conversion specifies the text to search for, to locate the error line. |
231 | 1279 The text is used as a literal string. The anchors "^" and "$" are added to |
1280 the text to locate the error line exactly matching the search text and the | |
1281 text is prefixed with the "\V" atom to make it "very nomagic". The "%s" | |
1282 conversion can be used to locate lines without a line number in the error | |
1283 output. Like the output of the "grep" shell command. | |
1284 When the pattern is present the line number will not be used. | |

1294 format strings. At most one of them may be given as a prefix at the beginning |
7 | 1295 of a single comma-separated format pattern. |
1296 Some compilers produce messages that consist of directory names that have to | |
237 | 1297 be prepended to each file name read by %f (example: GNU make). The following |
7 | 1298 codes can be used to scan these directory names; they will be stored in an |
1299 internal directory stack. *E379* | |
1300 %D "enter directory" format string; expects a following | |
1301 %f that finds the directory name | |
1302 %X "leave directory" format string; expects following %f | |
1303 | |
1304 When defining an "enter directory" or "leave directory" format, the "%D" or | |
237 | 1305 "%X" has to be given at the start of that substring. Vim tracks the directory |
7 | 1306 changes and prepends the current directory to each erroneous file found with a |
1307 relative path. See |quickfix-directory-stack| for details, tips and | |
1308 limitations. | |
1309 | |
1310 | |
1311 Multi-line messages *errorformat-multi-line* | |
1312 | |
1313 It is possible to read the output of programs that produce multi-line | |
237 | 1314 messages, i.e. error strings that consume more than one line. Possible |
7 | 1315 prefixes are: |
1316 %E start of a multi-line error message | |
1317 %W start of a multi-line warning message | |
1318 %I start of a multi-line informational message | |
1319 %A start of a multi-line message (unspecified type) | |
791 | 1320 %> for next line start with current pattern again |efm-%>| |
7 | 1321 %C continuation of a multi-line message |
1322 %Z end of a multi-line message | |
1323 These can be used with '+' and '-', see |efm-ignore| below. | |
1324 | |
787 | 1325 Using "\n" in the pattern won't work to match multi-line messages. |
1326 | |
7 | 1327 Example: Your compiler happens to write out errors in the following format |
1328 (leading line numbers not being part of the actual output): | |
1329 | |
787 | 1330 1 Error 275 ~ |
1331 2 line 42 ~ | |
1332 3 column 3 ~ | |
1333 4 ' ' expected after '--' ~ | |
7 | 1334 |
1335 The appropriate error format string has to look like this: > | |
1336 :set efm=%EError\ %n,%Cline\ %l,%Ccolumn\ %c,%Z%m | |
1337 | |
1338 And the |:clist| error message generated for this error is: | |
1339 | |
1340 1:42 col 3 error 275: ' ' expected after '--' | |
1341 | |
1342 Another example: Think of a Python interpreter that produces the following | |
1343 error message (line numbers are not part of the actual output): | |
1344 | |
1345 1 ============================================================== | |
1346 2 FAIL: testGetTypeIdCachesResult (dbfacadeTest.DjsDBFacadeTest) | |

1359 Say you want |:clist| write the relevant information of this message only, | |
1360 namely: | |
1361 5 unittests/dbfacadeTest.py:89: AssertionError: 34 != 33 | |
1362 | |
1363 Then the error format string could be defined as follows: > | |
1364 :set efm=%C\ %.%#,%A\ \ File\ \"%f\"\\,\ line\ %l%.%#,%Z%[%^\ ]%\\@=%m | |
1365 | |
1366 Note that the %C string is given before the %A here: since the expression | |
1367 ' %.%#' (which stands for the regular expression ' .*') matches every line | |
1368 starting with a space, followed by any characters to the end of the line, | |
1369 it also hides line 7 which would trigger a separate error message otherwise. | |
1370 Error format strings are always parsed pattern by pattern until the first | |
1371 match occurs. | |
791 | 1372 *efm-%>* |
1373 The %> item can be used to avoid trying patterns that appear earlier in | |
1374 'errorformat'. This is useful for patterns that match just about anything. | |
1375 For example, if the error looks like this: | |
1376 | |
1377 Error in line 123 of foo.c: ~ | |
1378 unknown variable "i" ~ | |
1379 | |
1380 This can be found with: > | |
1381 :set efm=xxx,%E%>Error in line %l of %f:,%Z%m | |
1382 Where "xxx" has a pattern that would also match the second line. | |
7 | 1383 |
787 | 1384 Important: There is no memory of what part of the errorformat matched before; |
1385 every line in the error file gets a complete new run through the error format | |
1386 lines. For example, if one has: > | |
1387 setlocal efm=aa,bb,cc,dd,ee | |
1388 Where aa, bb, etc. are error format strings. Each line of the error file will | |
1389 be matched to the pattern aa, then bb, then cc, etc. Just because cc matched | |
1390 the previous error line does _not_ mean that dd will be tried first on the | |
1391 current line, even if cc and dd are multi-line errorformat strings. | |
1392 | |
1393 | |
7 | 1394 |
1395 Separate file name *errorformat-separate-filename* | |
1396 | |
1397 These prefixes are useful if the file name is given once and multiple messages | |
1398 follow that refer to this file name. | |
1399 %O single-line file message: overread the matched part | |
1400 %P single-line file message: push file %f onto the stack | |
1401 %Q single-line file message: pop the last file from stack | |
1402 | |
1403 Example: Given a compiler that produces the following error logfile (without | |
1404 leading line numbers): | |
1405 | |
1406 1 [a1.tt] | |
1407 2 (1,17) error: ';' missing | |
1408 3 (21,2) warning: variable 'z' not defined | |
1409 4 (67,3) error: end of file found before string ended | |
1410 5 | |
1411 6 [a2.tt] | |
1412 7 | |
1413 8 [a3.tt] | |
1414 9 NEW compiler v1.1 | |
1415 10 (2,2) warning: variable 'x' not defined | |
1416 11 (67,3) warning: 's' already defined | |
1417 | |
1418 This logfile lists several messages for each file enclosed in [...] which are | |
1419 properly parsed by an error format like this: > | |
1420 :set efm=%+P[%f],(%l\\,%c)%*[\ ]%t%*[^:]:\ %m,%-Q | |
1421 | |
1422 A call of |:clist| writes them accordingly with their correct filenames: | |
1423 | |
1424 2 a1.tt:1 col 17 error: ';' missing | |
1425 3 a1.tt:21 col 2 warning: variable 'z' not defined | |
1426 4 a1.tt:67 col 3 error: end of file found before string ended | |
1427 8 a3.tt:2 col 2 warning: variable 'x' not defined | |
1428 9 a3.tt:67 col 3 warning: 's' already defined | |
1429 | |
1430 Unlike the other prefixes that all match against whole lines, %P, %Q and %O | |
237 | 1431 can be used to match several patterns in the same line. Thus it is possible |
7 | 1432 to parse even nested files like in the following line: |
1433 {"file1" {"file2" error1} error2 {"file3" error3 {"file4" error4 error5}}} | |
1434 The %O then parses over strings that do not contain any push/pop file name | |
1435 information. See |errorformat-LaTeX| for an extended example. | |
1436 | |
1437 | |
1438 Ignoring and using whole messages *efm-ignore* | |
1439 | |
1440 The codes '+' or '-' can be combined with the uppercase codes above; in that | |
237 | 1441 case they have to precede the letter, e.g. '%+A' or '%-G': |
7 | 1442 %- do not include the matching multi-line in any output |
1443 %+ include the whole matching line in the %m error string | |
1444 | |
237 | 1445 One prefix is only useful in combination with '+' or '-', namely %G. It parses |
7 | 1446 over lines containing general information like compiler version strings or |
1447 other headers that can be skipped. | |
1448 %-G ignore this message | |
1449 %+G general message | |
1450 | |
1451 | |
1452 Pattern matching | |
1453 | |
1454 The scanf()-like "%*[]" notation is supported for backward-compatibility | |
1455 with previous versions of Vim. However, it is also possible to specify | |
1456 (nearly) any Vim supported regular expression in format strings. | |
1457 Since meta characters of the regular expression language can be part of | |
1458 ordinary matching strings or file names (and therefore internally have to | |
1459 be escaped), meta symbols have to be written with leading '%': | |
787 | 1460 %\ The single '\' character. Note that this has to be |
7 | 1461 escaped ("%\\") in ":set errorformat=" definitions. |
787 | 1462 %. The single '.' character. |
1463 %# The single '*'(!) character. | |
1464 %^ The single '^' character. Note that this is not | |
1465 useful, the pattern already matches start of line. | |
1466 %$ The single '$' character. Note that this is not | |
1467 useful, the pattern already matches end of line. | |
1468 %[ The single '[' character for a [] character range. | |
1469 %~ The single '~' character. | |
7 | 1470 When using character classes in expressions (see |/\i| for an overview), |
1471 terms containing the "\+" quantifier can be written in the scanf() "%*" | |
237 | 1472 notation. Example: "%\\d%\\+" ("\d\+", "any number") is equivalent to "%*\\d". |
7 | 1473 Important note: The \(...\) grouping of sub-matches can not be used in format |
1474 specifications because it is reserved for internal conversions. | |
1475 | |
1476 | |
1477 Multiple entries in 'errorformat' *efm-entries* | |
1478 | |
1479 To be able to detect output from several compilers, several format patterns | |
1480 may be put in 'errorformat', separated by commas (note: blanks after the comma | |
1481 are ignored). The first pattern that has a complete match is used. If no | |
1482 match is found, matching parts from the last one will be used, although the | |
1483 file name is removed and the error message is set to the whole message. If | |
1484 there is a pattern that may match output from several compilers (but not in a | |
1485 right way), put it after one that is more restrictive. | |
1486 | |
1487 To include a comma in a pattern precede it with a backslash (you have to type | |
1488 two in a ":set" command). To include a backslash itself give two backslashes | |
1489 (you have to type four in a ":set" command). You also need to put a backslash | |
1490 before a space for ":set". | |
1491 | |
1492 | |
1493 Valid matches *quickfix-valid* | |
1494 | |
1495 If a line does not completely match one of the entries in 'errorformat', the | |
1496 whole line is put in the error message and the entry is marked "not valid" | |
1497 These lines are skipped with the ":cn" and ":cp" commands (unless there is | |
1498 no valid line at all). You can use ":cl!" to display all the error messages. | |
1499 | |
1500 If the error format does not contain a file name Vim cannot switch to the | |
1501 correct file. You will have to do this by hand. | |
1502 | |
1503 | |
1504 Examples | |
1505 | |
1506 The format of the file from the Amiga Aztec compiler is: | |
1507 | |
1508 filename>linenumber:columnnumber:errortype:errornumber:errormessage | |
1509 | |
1510 filename name of the file in which the error was detected | |
1511 linenumber line number where the error was detected | |
1512 columnnumber column number where the error was detected | |
1513 errortype type of the error, normally a single 'E' or 'W' | |
1514 errornumber number of the error (for lookup in the manual) | |
1515 errormessage description of the error | |
1516 | |
1517 This can be matched with this 'errorformat' entry: | |
1518 %f>%l:%c:%t:%n:%m | |
1519 | |
1520 Some examples for C compilers that produce single-line error outputs: | |
1521 %f:%l:\ %t%*[^0123456789]%n:\ %m for Manx/Aztec C error messages | |
1522 (scanf() doesn't understand [0-9]) | |

1534 Extended examples for the handling of multi-line messages are given below, | |
1535 see |errorformat-Jikes| and |errorformat-LaTeX|. | |
1536 | |
1537 Note the backslash in front of a space and double quote. It is required for | |
1538 the :set command. There are two backslashes in front of a comma, one for the | |
1539 :set command and one to avoid recognizing the comma as a separator of error | |
1540 formats. | |
1541 | |
1542 | |
1543 Filtering messages | |
1544 | |
1545 If you have a compiler that produces error messages that do not fit in the | |
1546 format string, you could write a program that translates the error messages | |
1547 into this format. You can use this program with the ":make" command by | |
1548 changing the 'makeprg' option. For example: > | |
1549 :set mp=make\ \\\|&\ error_filter | |
1550 The backslashes before the pipe character are required to avoid it to be | |
1551 recognized as a command separator. The backslash before each space is | |
1552 required for the set command. | |
1553 | |
1554 ============================================================================= | |
1555 8. The directory stack *quickfix-directory-stack* | |
1556 | |
1557 Quickfix maintains a stack for saving all used directories parsed from the | |
237 | 1558 make output. For GNU-make this is rather simple, as it always prints the |
1559 absolute path of all directories it enters and leaves. Regardless if this is | |
7 | 1560 done via a 'cd' command in the makefile or with the parameter "-C dir" (change |
237 | 1561 to directory before reading the makefile). It may be useful to use the switch |
7 | 1562 "-w" to force GNU-make to print out the working directory before and after |
1563 processing. | |
1564 | |
1565 Maintaining the correct directory is more complicated if you don't use | |
237 | 1566 GNU-make. AIX-make for example doesn't print any information about its |
1567 working directory. Then you need to enhance the makefile. In the makefile of | |
1568 LessTif there is a command which echoes "Making {target} in {dir}". The | |
2072 | 1569 special problem here is that it doesn't print information on leaving the |
237 | 1570 directory and that it doesn't print the absolute path. |
7 | 1571 |
1572 To solve the problem with relative paths and missing "leave directory" | |
1573 messages Vim uses following algorithm: | |
1574 | |
1575 1) Check if the given directory is a subdirectory of the current directory. | |
1576 If this is true, store it as the current directory. | |
1577 2) If it is not a subdir of the current directory, try if this is a | |
1578 subdirectory of one of the upper directories. | |
1579 3) If the directory still isn't found, it is assumed to be a subdirectory | |
1580 of Vim's current directory. | |
1581 | |
1582 Additionally it is checked for every file, if it really exists in the | |
1583 identified directory. If not, it is searched in all other directories of the | |
237 | 1584 directory stack (NOT the directory subtree!). If it is still not found, it is |
7 | 1585 assumed that it is in Vim's current directory. |
1586 | |

1587 There are limitations in this algorithm. These examples assume that make just |
7 | 1588 prints information about entering a directory in the form "Making all in dir". |
1589 | |
1590 1) Assume you have following directories and files: | |
1591 ./dir1 | |
1592 ./dir1/file1.c | |
1593 ./file1.c | |
1594 | |
1595 If make processes the directory "./dir1" before the current directory and | |
1596 there is an error in the file "./file1.c", you will end up with the file | |
1597 "./dir1/file.c" loaded by Vim. | |
1598 | |
1599 This can only be solved with a "leave directory" message. | |
1600 | |
1601 2) Assume you have following directories and files: | |
1602 ./dir1 | |
1603 ./dir1/dir2 | |
1604 ./dir2 | |
1605 | |
1606 You get the following: | |
1607 | |
1608 Make output Directory interpreted by Vim | |
1609 ------------------------ ---------------------------- | |
1610 Making all in dir1 ./dir1 | |
1611 Making all in dir2 ./dir1/dir2 | |
1612 Making all in dir2 ./dir1/dir2 | |
1613 | |
1614 This can be solved by printing absolute directories in the "enter directory" | |
11062 | 1615 message or by printing "leave directory" messages. |

1617 To avoid this problem, ensure to print absolute directory names and "leave |

1620 Examples for Makefiles: | |
1621 | |
1622 Unix: | |
1623 libs: | |
1624 for dn in $(LIBDIRS); do \ | |
1625 (cd $$dn; echo "Entering dir '$$(pwd)'"; make); \ | |
1626 echo "Leaving dir"; \ | |
1627 done | |
1628 | |
1629 Add | |
1630 %DEntering\ dir\ '%f',%XLeaving\ dir | |
1631 to your 'errorformat' to handle the above output. | |
1632 | |
1633 Note that Vim doesn't check if the directory name in a "leave directory" | |
237 | 1634 messages is the current directory. This is why you could just use the message |
7 | 1635 "Leaving dir". |

1638 9. Specific error file formats *errorformats* | |
1639 | |
1640 *errorformat-Jikes* | |
1641 Jikes(TM), a source-to-bytecode Java compiler published by IBM Research, | |
1642 produces simple multi-line error messages. | |
1643 | |
1644 An 'errorformat' string matching the produced messages is shown below. | |
1645 The following lines can be placed in the user's |vimrc| to overwrite Vim's | |
1646 recognized default formats, or see |:set+=| how to install this format | |
1647 additionally to the default. > | |
1648 | |
1649 :set efm=%A%f:%l:%c:%*\\d:%*\\d:, | |
1650 \%C%*\\s%trror:%m, | |
1651 \%+C%*[^:]%trror:%m, | |
1652 \%C%*\\s%tarning:%m, | |
1653 \%C%m | |
1654 < | |
1655 Jikes(TM) produces a single-line error message when invoked with the option | |
1656 "+E", and can be matched with the following: > | |
1657 | |
1167 | 1658 :setl efm=%f:%l:%v:%*\\d:%*\\d:%*\\s%m |
7 | 1659 < |
1660 *errorformat-javac* | |
1661 This 'errorformat' has been reported to work well for javac, which outputs a | |
1662 line with "^" to indicate the column of the error: > | |
1167 | 1663 :setl efm=%A%f:%l:\ %m,%-Z%p^,%-C%.%# |
7 | 1664 or: > |
1167 | 1665 :setl efm=%A%f:%l:\ %m,%+Z%p^,%+C%.%#,%-G%.%# |
7 | 1666 < |
1167 | 1667 Here is an alternative from Michael F. Lamb for Unix that filters the errors |
1668 first: > | |
1669 :setl errorformat=%Z%f:%l:\ %m,%A%p^,%-G%*[^sl]%.%# | |
5690 | 1670 :setl makeprg=javac\ %:S\ 2>&1\ \\\|\ vim-javac-filter |
1167 | 1671 |
1672 You need to put the following in "vim-javac-filter" somewhere in your path | |
1673 (e.g., in ~/bin) and make it executable: > | |
1674 #!/bin/sed -f | |
1675 /\^$/s/\t/\ /g;/:[0-9]\+:/{h;d};/^[ \t]*\^/G; | |
1676 | |
1677 In English, that sed script: | |
1678 - Changes single tabs to single spaces and | |
1679 - Moves the line with the filename, line number, error message to just after | |
1680 the pointer line. That way, the unused error text between doesn't break | |
1681 vim's notion of a "multi-line message" and also doesn't force us to include | |
1682 it as a "continuation of a multi-line message." | |
1683 | |
7 | 1684 *errorformat-ant* |
1685 For ant (http://jakarta.apache.org/) the above errorformat has to be modified | |
1686 to honour the leading [javac] in front of each javac output line: > | |
1687 :set efm=%A\ %#[javac]\ %f:%l:\ %m,%-Z\ %#[javac]\ %p^,%-C%.%# | |
1688 | |
1689 The 'errorformat' can also be configured to handle ant together with either | |
1690 javac or jikes. If you're using jikes, you should tell ant to use jikes' +E | |
1691 command line switch which forces jikes to generate one-line error messages. | |
1692 This is what the second line (of a build.xml file) below does: > | |
1693 <property name = "build.compiler" value = "jikes"/> | |
1694 <property name = "build.compiler.emacs" value = "true"/> | |
1695 | |
1696 The 'errorformat' which handles ant with both javac and jikes is: > | |
1697 :set efm=\ %#[javac]\ %#%f:%l:%c:%*\\d:%*\\d:\ %t%[%^:]%#:%m, | |
1698 \%A\ %#[javac]\ %f:%l:\ %m,%-Z\ %#[javac]\ %p^,%-C%.%# | |
1699 < | |
1700 *errorformat-jade* | |
1701 parsing jade (see http://www.jclark.com/) errors is simple: > | |
1702 :set efm=jade:%f:%l:%c:%t:%m | |
1703 < | |
1704 *errorformat-LaTeX* | |
1705 The following is an example how an 'errorformat' string can be specified | |
1706 for the (La)TeX typesetting system which displays error messages over | |
1707 multiple lines. The output of ":clist" and ":cc" etc. commands displays | |
1708 multi-lines in a single line, leading white space is removed. | |
1709 It should be easy to adopt the above LaTeX errorformat to any compiler output | |
1710 consisting of multi-line errors. | |
1711 | |
1712 The commands can be placed in a |vimrc| file or some other Vim script file, | |
237 | 1713 e.g. a script containing LaTeX related stuff which is loaded only when editing |
7 | 1714 LaTeX sources. |
1715 Make sure to copy all lines of the example (in the given order), afterwards | |
1716 remove the comment lines. For the '\' notation at the start of some lines see | |
1717 |line-continuation|. | |
1718 | |
1719 First prepare 'makeprg' such that LaTeX will report multiple | |
1720 errors; do not stop when the first error has occurred: > | |
1721 :set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*} | |
1722 < | |
1723 Start of multi-line error messages: > | |
1724 :set efm=%E!\ LaTeX\ %trror:\ %m, | |
1725 \%E!\ %m, | |
1726 < Start of multi-line warning messages; the first two also | |
237 | 1727 include the line number. Meaning of some regular expressions: |
7 | 1728 - "%.%#" (".*") matches a (possibly empty) string |
1729 - "%*\\d" ("\d\+") matches a number > | |
1730 \%+WLaTeX\ %.%#Warning:\ %.%#line\ %l%.%#, | |
1731 \%+W%.%#\ at\ lines\ %l--%*\\d, | |
1732 \%WLaTeX\ %.%#Warning:\ %m, | |
1733 < Possible continuations of error/warning messages; the first | |
1734 one also includes the line number: > | |
1735 \%Cl.%l\ %m, | |
1736 \%+C\ \ %m., | |
1737 \%+C%.%#-%.%#, | |
1738 \%+C%.%#[]%.%#, | |
1739 \%+C[]%.%#, | |
1740 \%+C%.%#%[{}\\]%.%#, | |
1741 \%+C<%.%#>%.%#, | |
1742 \%C\ \ %m, | |
1743 < Lines that match the following patterns do not contain any | |
1744 important information; do not include them in messages: > | |
1745 \%-GSee\ the\ LaTeX%m, | |
1746 \%-GType\ \ H\ <return>%m, | |
1747 \%-G\ ...%.%#, | |
1748 \%-G%.%#\ (C)\ %.%#, | |
1749 \%-G(see\ the\ transcript%.%#), | |
1750 < Generally exclude any empty or whitespace-only line from | |
1751 being displayed: > | |
1752 \%-G\\s%#, | |
1753 < The LaTeX output log does not specify the names of erroneous | |
1754 source files per line; rather they are given globally, | |
1755 enclosed in parentheses. | |
1756 The following patterns try to match these names and store | |
1757 them in an internal stack. The patterns possibly scan over | |
1758 the same input line (one after another), the trailing "%r" | |
1759 conversion indicates the "rest" of the line that will be | |
1760 parsed in the next go until the end of line is reached. | |
1761 | |
1762 Overread a file name enclosed in '('...')'; do not push it | |
1763 on a stack since the file apparently does not contain any | |
1764 error: > | |
1765 \%+O(%f)%r, | |
237 | 1766 < Push a file name onto the stack. The name is given after '(': > |
7 | 1767 \%+P(%f%r, |
1768 \%+P\ %\\=(%f%r, | |
1769 \%+P%*[^()](%f%r, | |
1770 \%+P[%\\d%[^()]%#(%f%r, | |
1771 < Pop the last stored file name when a ')' is scanned: > | |
1772 \%+Q)%r, | |
1773 \%+Q%*[^()])%r, | |
1774 \%+Q[%\\d%*[^()])%r | |
1775 | |
1776 Note that in some cases file names in the LaTeX output log cannot be parsed | |
1777 properly. The parser might have been messed up by unbalanced parentheses | |
1778 then. The above example tries to catch the most relevant cases only. | |
1779 You can customize the given setting to suit your own purposes, for example, | |
1780 all the annoying "Overfull ..." warnings could be excluded from being | |
1781 recognized as an error. | |
1782 Alternatively to filtering the LaTeX compiler output, it is also possible | |
1783 to directly read the *.log file that is produced by the [La]TeX compiler. | |
1784 This contains even more useful information about possible error causes. | |
1785 However, to properly parse such a complex file, an external filter should | |
1786 be used. See the description further above how to make such a filter known | |
1787 by Vim. | |
1788 | |
1789 *errorformat-Perl* | |
1790 In $VIMRUNTIME/tools you can find the efm_perl.pl script, which filters Perl | |
1791 error messages into a format that quickfix mode will understand. See the | |
1624 | 1792 start of the file about how to use it. (This script is deprecated, see |
1793 |compiler-perl|.) | |
