patch 8.0.1668: terminal debugger: can't re-open source code window
Problem: Terminal debugger: can't re-open source code window.
Solution: Add the :Source command. Also create the window if needed when
gdb stops at a source line.

16 8. MzScheme setup |mzscheme-setup| |
| 14 | 17 |
| 18 {Vi does not have any of these commands} | |
| 19 | |
| 20 The MzScheme interface is available only if Vim was compiled with the | |
| 21 |+mzscheme| feature. | |
| 22 | |
| 23 Based on the work of Brent Fulgham. | |
| 128 | 24 Dynamic loading added by Sergey Khorev |
| 14 | 25 |
| 4074 | 26 MzScheme and PLT Scheme names have been rebranded as Racket. For more |
| 27 information please check http://racket-lang.org | |
| 14 | 28 |
| 4074 | 29 Futures and places of Racket version 5.x up to and including 5.3.1 do not |
| 30 work correctly with processes created by Vim. | |
| 31 The simplest solution is to build Racket on your own with these features | |
| 32 disabled: > | |
| 33 ./configure --disable-futures --disable-places --prefix=your-install-prefix | |
| 34 | |
| 35 To speed up the process, you might also want to use --disable-gracket and | |
| 36 --disable-docs | |
| 1121 | 37 |
| 14 | 38 ============================================================================== |
| 39 1. Commands *mzscheme-commands* | |
| 40 | |
| 41 *:mzscheme* *:mz* | |
| 42 :[range]mz[scheme] {stmt} | |
| 43 Execute MzScheme statement {stmt}. {not in Vi} | |
| 44 | |
| 45 :[range]mz[scheme] << {endmarker} | |
| 46 {script} | |
| 47 {endmarker} | |
| 48 Execute inlined MzScheme script {script}. | |
| 49 Note: This command doesn't work if the MzScheme | |
| 50 feature wasn't compiled in. To avoid errors, see | |
| 51 |script-here|. | |
| 52 | |
| 53 *:mzfile* *:mzf* | |
| 54 :[range]mzf[ile] {file} Execute the MzScheme script in {file}. {not in Vi} | |
| 55 | |
| 56 All of these commands do essentially the same thing - they execute a piece of | |
| 57 MzScheme code, with the "current range" set to the given line | |
| 58 range. | |
| 59 | |
| 60 In the case of :mzscheme, the code to execute is in the command-line. | |
| 61 In the case of :mzfile, the code to execute is the contents of the given file. | |
| 62 | |
| 63 MzScheme interface defines exception exn:vim, derived from exn. | |
| 64 It is raised for various Vim errors. | |
| 65 | |
| 66 During compilation, the MzScheme interface will remember the current MzScheme | |
| 67 collection path. If you want to specify additional paths use the | |
| 68 'current-library-collection-paths' parameter. E.g., to cons the user-local | |
| 69 MzScheme collection path: > | |
| 70 :mz << EOF | |
| 71 (current-library-collection-paths | |
| 72 (cons | |
| 73 (build-path (find-system-path 'addon-dir) (version) "collects") | |
| 74 (current-library-collection-paths))) | |
| 75 EOF | |
| 76 < | |
| 77 | |
| 78 All functionality is provided through module vimext. | |
| 79 | |
| 80 The exn:vim is available without explicit import. | |
| 81 | |
| 82 To avoid clashes with MzScheme, consider using prefix when requiring module, | |
| 83 e.g.: > | |
| 84 :mzscheme (require (prefix vim- vimext)) | |
| 85 < | |
| 1894 | 86 All the examples below assume this naming scheme. |
| 14 | 87 |
| 273 | 88 *mzscheme-sandbox* |
| 89 When executed in the |sandbox|, access to some filesystem and Vim interface | |
| 90 procedures is restricted. | |
| 14 | 91 |
| 92 ============================================================================== | |
| 93 2. Examples *mzscheme-examples* | |
| 94 > | |
| 95 :mzscheme (display "Hello") | |
| 1894 | 96 :mz (display (string-append "Using MzScheme version " (version))) |
| 97 :mzscheme (require (prefix vim- vimext)) ; for MzScheme < 4.x | |
| 98 :mzscheme (require (prefix-in vim- 'vimext)) ; MzScheme 4.x | |
| 14 | 99 :mzscheme (vim-set-buff-line 10 "This is line #10") |

| 148 3. Threads *mzscheme-threads* | |
| 149 | |
| 150 The MzScheme interface supports threads. They are independent from OS threads, | |
| 151 thus scheduling is required. The option 'mzquantum' determines how often | |
| 152 Vim should poll for available MzScheme threads. | |
| 153 NOTE | |
| 154 Thread scheduling in the console version of Vim is less reliable than in the | |
| 155 GUI version. | |

158 4. Vim access from MzScheme *mzscheme-vim* |
| 14 | 159 |
| 160 *mzscheme-vimext* | |
| 161 The 'vimext' module provides access to procedures defined in the MzScheme | |
| 162 interface. | |
| 163 | |
| 164 Common | |
| 165 ------ | |
| 166 (command {command-string}) Perform the vim ":Ex" style command. | |
| 1894 | 167 (eval {expr-string}) Evaluate the vim expression into |
| 168 respective MzScheme object: |Lists| are | |
| 169 represented as Scheme lists, | |
| 4074 | 170 |Dictionaries| as hash tables, |
| 171 |Funcref|s as functions (see also | |
| 172 |mzscheme-funcref|) | |
| 173 NOTE the name clashes with MzScheme eval, | |
| 174 use module qualifiers to overcome this. | |
| 14 | 175 (range-start) Start/End of the range passed with |
| 176 (range-end) the Scheme command. | |
| 177 (beep) beep | |
| 178 (get-option {option-name} [buffer-or-window]) Get Vim option value (either | |
| 179 local or global, see set-option). | |
| 180 (set-option {string} [buffer-or-window]) | |
| 181 Set a Vim option. String must have option | |
| 182 setting form (like optname=optval, or | |
| 183 optname+=optval, etc.) When called with | |
| 184 {buffer} or {window} the local option will | |
| 185 be set. The symbol 'global can be passed | |
| 186 as {buffer-or-window}. Then |:setglobal| | |
| 187 will be used. | |
| 188 | |
| 189 Buffers *mzscheme-buffer* | |
| 190 ------- | |
| 191 (buff? {object}) Is object a buffer? | |
| 192 (buff-valid? {object}) Is object a valid buffer? (i.e. | |
| 193 corresponds to the real Vim buffer) | |
| 194 (get-buff-line {linenr} [buffer]) | |
| 195 Get line from a buffer. | |
| 196 (set-buff-line {linenr} {string} [buffer]) | |
| 197 Set a line in a buffer. If {string} is #f, | |
| 198 the line gets deleted. The [buffer] | |
| 856 | 199 argument is optional. If omitted, the |
| 200 current buffer will be used. | |
| 14 | 201 (get-buff-line-list {start} {end} [buffer]) |
| 202 Get a list of lines in a buffer. {Start} | |

203 and {end} are 1-based and inclusive. |
| 14 | 204 (set-buff-line-list {start} {end} {string-list} [buffer]) |
| 205 Set a list of lines in a buffer. If | |
| 206 string-list is #f or null, the lines get | |
| 207 deleted. If a list is shorter than | |
| 208 {end}-{start} the remaining lines will | |
| 209 be deleted. | |
| 210 (get-buff-name [buffer]) Get a buffer's text name. | |
| 211 (get-buff-num [buffer]) Get a buffer's number. | |
| 212 (get-buff-size [buffer]) Get buffer line count. | |
| 213 (insert-buff-line-list {linenr} {string/string-list} [buffer]) | |
| 214 Insert a list of lines into a buffer after | |
| 215 {linenr}. If {linenr} is 0, lines will be | |
| 216 inserted at start. | |

218 interface procedures to change it. |

| 226 (get-buff-by-num {buffernum}) Get a buffer by its number (return #f if | |
| 227 there is no buffer with this number). | |
| 228 | |
| 229 Windows *mzscheme-window* | |
| 230 ------ | |
| 231 (win? {object}) Is object a window? | |
| 232 (win-valid? {object}) Is object a valid window (i.e. corresponds | |
| 233 to the real Vim window)? | |

| 4074 | 255 6. Using Function references *mzscheme-funcref* |
| 256 | |
| 257 MzScheme interface allows use of |Funcref|s so you can call Vim functions | |
| 258 directly from Scheme. For instance: > | |
| 259 function! MyAdd2(arg) | |
| 260 return a:arg + 2 | |
| 261 endfunction | |
| 262 mz (define f2 (vim-eval "function(\"MyAdd2\")")) | |
| 263 mz (f2 7) | |
| 264 < or : > | |
| 265 :mz (define indent (vim-eval "function('indent')")) | |
| 266 " return Vim indent for line 12 | |
| 267 :mz (indent 12) | |

271 7. Dynamic loading *mzscheme-dynamic* *E815* |
| 625 | 272 |
| 273 On MS-Windows the MzScheme libraries can be loaded dynamically. The |:version| | |
| 274 output then includes |+mzscheme/dyn|. | |
| 275 | |
| 276 This means that Vim will search for the MzScheme DLL files only when needed. | |
| 277 When you don't use the MzScheme interface you don't need them, thus you can | |
| 278 use Vim without these DLL files. | |

289 The version of the DLL must match the MzScheme version Vim was compiled with. |
| 625 | 290 For MzScheme version 209 they will be "libmzsch209_000.dll" and |
| 1121 | 291 "libmzgc209_000.dll". To know for sure look at the output of the ":version" |
