1620 | 195 " Vim support for OCaml .annot files |
196 " | |
197 " Last Change: 2007 Jul 17 | |
198 " Maintainer: Vincent Aravantinos <vincent.aravantinos@gmail.com> | |
199 " License: public domain | |
20 | 200 " |
1620 | 201 " Originally inspired by 'ocaml-dtypes.vim' by Stefano Zacchiroli. |
202 " The source code is quite radically different for we not use python anymore. | |
203 " However this plugin should have the exact same behaviour, that's why the | |
204 " following lines are the quite exact copy of Stefano's original plugin : | |
205 " | |
206 " << | |
207 " Executing Ocaml_print_type(<mode>) function will display in the Vim bottom | |
20 | 208 " line(s) the type of an ocaml value getting it from the corresponding .annot |
209 " file (if any). If Vim is in visual mode, <mode> should be "visual" and the | |
210 " selected ocaml value correspond to the highlighted text, otherwise (<mode> | |
211 " can be anything else) it corresponds to the literal found at the current | |
212 " cursor position. | |
213 " | |
1620 | 214 " Typing '<LocalLeader>t' (LocalLeader defaults to '\', see :h LocalLeader) |
3224 | 215 " will cause " Ocaml_print_type function to be invoked with the right |
1620 | 216 " argument depending on the current mode (visual or not). |
217 " >> | |
20 | 218 " |
1620 | 219 " If you find something not matching this behaviour, please signal it. |
20 | 220 " |
1620 | 221 " Differences are: |
222 " - no need for python support | |
223 " + plus : more portable | |
224 " + minus: no more lazy parsing, it looks very fast however | |
3224 | 225 " |
1620 | 226 " - ocamlbuild support, ie. |
3224 | 227 " + the plugin finds the _build directory and looks for the |
1620 | 228 " corresponding file inside; |
229 " + if the user decides to change the name of the _build directory thanks | |
230 " to the '-build-dir' option of ocamlbuild, the plugin will manage in | |
231 " most cases to find it out (most cases = if the source file has a unique | |
232 " name among your whole project); | |
233 " + if ocamlbuild is not used, the usual behaviour holds; ie. the .annot | |
234 " file should be in the same directory as the source file; | |
235 " + for vim plugin programmers: | |
3224 | 236 " the variable 'b:_build_dir' contains the inferred path to the build |
1620 | 237 " directory, even if this one is not named '_build'. |
238 " | |
239 " Bonus : | |
240 " - latin1 accents are handled | |
241 " - lists are handled, even on multiple lines, you don't need the visual mode | |
242 " (the cursor must be on the first bracket) | |
243 " - parenthesized expressions, arrays, and structures (ie. '(...)', '[|...|]', | |
244 " and '{...}') are handled the same way | |
20 | 245 |
1620 | 246 " Copied from Stefano's original plugin : |
247 " << | |
248 " .annot ocaml file representation | |
249 " | |
250 " File format (copied verbatim from caml-types.el) | |
251 " | |
252 " file ::= block * | |
253 " block ::= position <SP> position <LF> annotation * | |
254 " position ::= filename <SP> num <SP> num <SP> num | |
255 " annotation ::= keyword open-paren <LF> <SP> <SP> data <LF> close-paren | |
256 " | |
257 " <SP> is a space character (ASCII 0x20) | |
258 " <LF> is a line-feed character (ASCII 0x0A) | |
259 " num is a sequence of decimal digits | |
260 " filename is a string with the lexical conventions of O'Caml | |
261 " open-paren is an open parenthesis (ASCII 0x28) | |
262 " close-paren is a closed parenthesis (ASCII 0x29) | |
263 " data is any sequence of characters where <LF> is always followed by | |
264 " at least two space characters. | |
265 " | |
266 " - in each block, the two positions are respectively the start and the | |
267 " end of the range described by the block. | |
268 " - in a position, the filename is the name of the file, the first num | |
269 " is the line number, the second num is the offset of the beginning | |
270 " of the line, the third num is the offset of the position itself. | |
271 " - the char number within the line is the difference between the third | |
272 " and second nums. | |
273 " | |
274 " For the moment, the only possible keyword is \"type\"." | |
