|
|
|
14 {Vi does not have any of these commands}
|
|
|
15
|
|
|
16 The MzScheme interface is available only if Vim was compiled with the
|
|
|
17 |+mzscheme| feature.
|
|
|
18
|
|
|
19 Based on the work of Brent Fulgham.

|
|
|
25 1. Commands *mzscheme-commands*
|
|
|
26
|
|
|
27 *:mzscheme* *:mz*
|
|
|
28 :[range]mz[scheme] {stmt}
|
|
|
29 Execute MzScheme statement {stmt}. {not in Vi}
|
|
|
30
|
|
|
31 :[range]mz[scheme] << {endmarker}
|
|
|
32 {script}
|
|
|
33 {endmarker}
|
|
|
34 Execute inlined MzScheme script {script}.
|
|
|
35 Note: This command doesn't work if the MzScheme
|
|
|
36 feature wasn't compiled in. To avoid errors, see
|
|
|
37 |script-here|.
|
|
|
38
|
|
|
39 *:mzfile* *:mzf*
|
|
|
40 :[range]mzf[ile] {file} Execute the MzScheme script in {file}. {not in Vi}
|
|
|
41 All statements are executed in the namespace of the
|
|
|
42 buffer that was current during :mzfile start.
|
|
|
43 If you want to access other namespaces, use
|
|
|
44 'parameterize'.
|
|
|
45
|
|
|
46 All of these commands do essentially the same thing - they execute a piece of
|
|
|
47 MzScheme code, with the "current range" set to the given line
|
|
|
48 range.
|
|
|
49
|
|
|
50 In the case of :mzscheme, the code to execute is in the command-line.
|
|
|
51 In the case of :mzfile, the code to execute is the contents of the given file.
|
|
|
52
|
|
|
53 Each buffer has its own MzScheme namespace. Global namespace is bound to
|
|
|
54 the `global-namespace' value from the 'vimext' module.
|
|
|
55 MzScheme interface defines exception exn:vim, derived from exn.
|
|
|
56 It is raised for various Vim errors.
|
|
|
57
|
|
|
58 During compilation, the MzScheme interface will remember the current MzScheme
|
|
|
59 collection path. If you want to specify additional paths use the
|
|
|
60 'current-library-collection-paths' parameter. E.g., to cons the user-local
|
|
|
61 MzScheme collection path: >
|
|
|
62 :mz << EOF
|
|
|
63 (current-library-collection-paths
|
|
|
64 (cons
|
|
|
65 (build-path (find-system-path 'addon-dir) (version) "collects")
|
|
|
66 (current-library-collection-paths)))
|
|
|
67 EOF
|
|
|
68 <
|
|
|
69
|
|
|
70 All functionality is provided through module vimext.
|
|
|
71
|
|
|
72 The exn:vim is available without explicit import.
|
|
|
73
|
|
|
74 To avoid clashes with MzScheme, consider using prefix when requiring module,
|
|
|
75 e.g.: >
|
|
|
76 :mzscheme (require (prefix vim- vimext))
|
|
|
77 <
|
|
|
78 All the examples below assume this naming scheme. Note that you need to do
|
|
|
79 this again for every buffer.
|
|
|
80
|
|
|
81 The auto-instantiation can be achieved with autocommands, e.g. you can put
|
|
26
|
82 something like this in your .vimrc (EOFs should not have indentation): >
|
|
|
83 function s:MzRequire()
|
|
|
84 if has("mzscheme")
|
|
|
85 :mz << EOF
|
|
|
86 (require (prefix vim- vimext))
|
|
|
87 (let ((buf (vim-get-buff-by-name (vim-eval "expand(\"<afile>\")"))))
|
|
|
88 (when (and buf (not (eq? buf (vim-curr-buff))))
|
|
|
89 (parameterize ((current-namespace (vim-get-buff-namespace buf)))
|
|
|
90 (namespace-attach-module vim-global-namespace 'vimext)
|
|
|
91 (namespace-require '(prefix vim vimext)))))
|
|
|
92 EOF
|
|
|
93 endif
|
|
|
94 endfunction
|
|
|
95
|
|
|
96 function s:MzStartup()
|
|
|
97 if has("mzscheme")
|
|
|
98 au BufNew,BufNewFile,BufAdd,BufReadPre * :call s:MzRequire()
|
|
|
99 :mz << EOF
|
|
|
100 (current-library-collection-paths
|
|
|
101 (cons
|
|
|
102 (build-path (find-system-path 'addon-dir) (version) "collects")
|
|
|
103 (current-library-collection-paths)))
|
|
|
104 EOF
|
|
|
105 endif
|
|
|
106 endfunction
|
|
|
107
|
|
|
108 call s:MzStartup()
|
|
14
|
109 <
|
|
|
110
|
|
|
111 The global namespace just instantiated this module with the prefix "vimext:".

|
145 3. Threads *mzscheme-threads*
|
|
|
146
|
|
|
147 The MzScheme interface supports threads. They are independent from OS threads,
|
|
|
148 thus scheduling is required. The option 'mzquantum' determines how often
|
|
|
149 Vim should poll for available MzScheme threads.
|
|
|
150 NOTE
|
|
|
151 Thread scheduling in the console version of Vim is less reliable than in the
|
|
|
152 GUI version.

|
|

155 5. VIM Functions *mzscheme-vim*
|
|
|
156
|
|
|
157 *mzscheme-vimext*
|
|
|
158 The 'vimext' module provides access to procedures defined in the MzScheme
|
|
|
159 interface.
|
|
|
160
|
|
|
161 Common
|
|
|
162 ------
|
|
|
163 (command {command-string}) Perform the vim ":Ex" style command.
|
|
|
164 (eval {expr-string}) Evaluate the vim command string.
|
|
|
165 NOTE clashes with MzScheme eval
|
|
|
166 (range-start) Start/End of the range passed with
|
|
|
167 (range-end) the Scheme command.
|
|
|
168 (beep) beep
|
|
|
169 (get-option {option-name} [buffer-or-window]) Get Vim option value (either
|
|
|
170 local or global, see set-option).
|
|
|
171 (set-option {string} [buffer-or-window])
|
|
|
172 Set a Vim option. String must have option
|
|
|
173 setting form (like optname=optval, or
|
|
|
174 optname+=optval, etc.) When called with
|
|
|
175 {buffer} or {window} the local option will
|
|
|
176 be set. The symbol 'global can be passed
|
|
|
177 as {buffer-or-window}. Then |:setglobal|
|
|
|
178 will be used.
|
|
|
179 global-namespace The MzScheme main namespace.
|
|
|
180

|
|
181 Buffers *mzscheme-buffer*

|
|
|
209 inserted at start.
|
|
