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