updated for version 7.3.281
Problem: After using "expand('%:8')" the buffer name is changed.
Solution: Make a copy of the file name before shortening it.

14 6. Dynamic loading |mzscheme-dynamic| |
| 14 | 15 |
| 16 {Vi does not have any of these commands} | |
| 17 | |
| 18 The MzScheme interface is available only if Vim was compiled with the | |
| 19 |+mzscheme| feature. | |
| 20 | |
| 21 Based on the work of Brent Fulgham. | |
| 128 | 22 Dynamic loading added by Sergey Khorev |
| 14 | 23 |
| 24 For downloading MzScheme and other info: | |
| 25 http://www.plt-scheme.org/software/mzscheme/ | |
| 26 | |
| 1121 | 27 Note: On FreeBSD you should use the "drscheme" port. |
| 28 | |
| 14 | 29 ============================================================================== |
| 30 1. Commands *mzscheme-commands* | |
| 31 | |
| 32 *:mzscheme* *:mz* | |
| 33 :[range]mz[scheme] {stmt} | |
| 34 Execute MzScheme statement {stmt}. {not in Vi} | |
| 35 | |
| 36 :[range]mz[scheme] << {endmarker} | |
| 37 {script} | |
| 38 {endmarker} | |
| 39 Execute inlined MzScheme script {script}. | |
| 40 Note: This command doesn't work if the MzScheme | |
| 41 feature wasn't compiled in. To avoid errors, see | |
| 42 |script-here|. | |
| 43 | |
| 44 *:mzfile* *:mzf* | |
| 45 :[range]mzf[ile] {file} Execute the MzScheme script in {file}. {not in Vi} | |
| 46 | |
| 47 All of these commands do essentially the same thing - they execute a piece of | |
| 48 MzScheme code, with the "current range" set to the given line | |
| 49 range. | |
| 50 | |
| 51 In the case of :mzscheme, the code to execute is in the command-line. | |
| 52 In the case of :mzfile, the code to execute is the contents of the given file. | |
| 53 | |
| 54 MzScheme interface defines exception exn:vim, derived from exn. | |
| 55 It is raised for various Vim errors. | |
| 56 | |
| 57 During compilation, the MzScheme interface will remember the current MzScheme | |
| 58 collection path. If you want to specify additional paths use the | |
| 59 'current-library-collection-paths' parameter. E.g., to cons the user-local | |
| 60 MzScheme collection path: > | |
| 61 :mz << EOF | |
| 62 (current-library-collection-paths | |
| 63 (cons | |
| 64 (build-path (find-system-path 'addon-dir) (version) "collects") | |
| 65 (current-library-collection-paths))) | |
| 66 EOF | |
| 67 < | |
| 68 | |
| 69 All functionality is provided through module vimext. | |
| 70 | |
| 71 The exn:vim is available without explicit import. | |
| 72 | |
| 73 To avoid clashes with MzScheme, consider using prefix when requiring module, | |
| 74 e.g.: > | |
| 75 :mzscheme (require (prefix vim- vimext)) | |
| 76 < | |
| 1894 | 77 All the examples below assume this naming scheme. |
| 14 | 78 |
| 273 | 79 *mzscheme-sandbox* |
| 80 When executed in the |sandbox|, access to some filesystem and Vim interface | |
| 81 procedures is restricted. | |

| 84 2. Examples *mzscheme-examples* | |

| 113 ([exn:vim? (lambda (e) (display (exn-message e)))]) | |
| 114 (vim-eval "nonsense-string")) | |

| 132 silent call MzRequire() | |

| 134 < | |
| 14 | 135 ============================================================================== |
| 136 3. Threads *mzscheme-threads* | |
| 137 | |
| 138 The MzScheme interface supports threads. They are independent from OS threads, | |
| 139 thus scheduling is required. The option 'mzquantum' determines how often | |
| 140 Vim should poll for available MzScheme threads. | |
| 141 NOTE | |
| 142 Thread scheduling in the console version of Vim is less reliable than in the | |
| 143 GUI version. | |
| 144 | |

146 4. Vim access from MzScheme *mzscheme-vim* |
| 14 | 147 |
| 148 *mzscheme-vimext* | |
| 149 The 'vimext' module provides access to procedures defined in the MzScheme | |
| 150 interface. | |
| 151 | |
| 152 Common | |
| 153 ------ | |
| 154 (command {command-string}) Perform the vim ":Ex" style command. | |
| 1894 | 155 (eval {expr-string}) Evaluate the vim expression into |
| 156 respective MzScheme object: |Lists| are | |
| 157 represented as Scheme lists, | |
| 158 |Dictionaries| as hash tables. | |
| 159 NOTE the name clashes with MzScheme eval | |
| 14 | 160 (range-start) Start/End of the range passed with |
| 161 (range-end) the Scheme command. | |
| 162 (beep) beep | |
| 163 (get-option {option-name} [buffer-or-window]) Get Vim option value (either | |
| 164 local or global, see set-option). | |
| 165 (set-option {string} [buffer-or-window]) | |
| 166 Set a Vim option. String must have option | |
| 167 setting form (like optname=optval, or | |
| 168 optname+=optval, etc.) When called with | |
| 169 {buffer} or {window} the local option will | |
| 170 be set. The symbol 'global can be passed | |
| 171 as {buffer-or-window}. Then |:setglobal| | |
| 172 will be used. | |
| 173 | |
| 174 Buffers *mzscheme-buffer* | |
| 175 ------- | |
| 176 (buff? {object}) Is object a buffer? | |
| 177 (buff-valid? {object}) Is object a valid buffer? (i.e. | |
| 178 corresponds to the real Vim buffer) | |
| 179 (get-buff-line {linenr} [buffer]) | |
| 180 Get line from a buffer. | |
| 181 (set-buff-line {linenr} {string} [buffer]) | |
| 182 Set a line in a buffer. If {string} is #f, | |
| 183 the line gets deleted. The [buffer] | |
| 856 | 184 argument is optional. If omitted, the |
| 185 current buffer will be used. | |
| 14 | 186 (get-buff-line-list {start} {end} [buffer]) |
| 187 Get a list of lines in a buffer. {Start} | |

188 and {end} are 1-based and inclusive. |
| 14 | 189 (set-buff-line-list {start} {end} {string-list} [buffer]) |
| 190 Set a list of lines in a buffer. If | |
| 191 string-list is #f or null, the lines get | |
| 192 deleted. If a list is shorter than | |
| 193 {end}-{start} the remaining lines will | |
| 194 be deleted. | |
| 195 (get-buff-name [buffer]) Get a buffer's text name. | |
| 196 (get-buff-num [buffer]) Get a buffer's number. | |
| 197 (get-buff-size [buffer]) Get buffer line count. | |
| 198 (insert-buff-line-list {linenr} {string/string-list} [buffer]) | |
| 199 Insert a list of lines into a buffer after | |
| 200 {linenr}. If {linenr} is 0, lines will be | |
| 201 inserted at start. | |

240 6. Dynamic loading *mzscheme-dynamic* *E815* |
| 625 | 241 |
| 242 On MS-Windows the MzScheme libraries can be loaded dynamically. The |:version| | |
| 243 output then includes |+mzscheme/dyn|. | |
| 244 | |
| 245 This means that Vim will search for the MzScheme DLL files only when needed. | |
| 246 When you don't use the MzScheme interface you don't need them, thus you can | |
| 247 use Vim without these DLL files. | |
| 248 | |
| 249 To use the MzScheme interface the MzScheme DLLs must be in your search path. | |
| 250 In a console window type "path" to see what directories are used. | |
| 251 | |
| 252 The names of the DLLs must match the MzScheme version Vim was compiled with. | |
| 253 For MzScheme version 209 they will be "libmzsch209_000.dll" and | |
| 1121 | 254 "libmzgc209_000.dll". To know for sure look at the output of the ":version" |
| 255 command, look for -DDYNAMIC_MZSCH_DLL="something" and | |
| 256 -DDYNAMIC_MZGC_DLL="something" in the "Compilation" info. | |
| 625 | 257 |
