" Vim support for OCaml .annot files
|
||
"
|
||
" Last Change: 2007 Jul 17
|
||
" Maintainer: Vincent Aravantinos <vincent.aravantinos@gmail.com>
|
||
" License: public domain
|
||
"
|
||
" Originally inspired by 'ocaml-dtypes.vim' by Stefano Zacchiroli.
|
||
" The source code is quite radically different for we not use python anymore.
|
||
" However this plugin should have the exact same behaviour, that's why the
|
||
" following lines are the quite exact copy of Stefano's original plugin :
|
||
"
|
||
" <<
|
||
" Executing Ocaml_print_type(<mode>) function will display in the Vim bottom
|
||
" line(s) the type of an ocaml value getting it from the corresponding .annot
|
||
" file (if any). If Vim is in visual mode, <mode> should be "visual" and the
|
||
" selected ocaml value correspond to the highlighted text, otherwise (<mode>
|
||
" can be anything else) it corresponds to the literal found at the current
|
||
" cursor position.
|
||
"
|
||
" Typing '<LocalLeader>t' (LocalLeader defaults to '\', see :h LocalLeader)
|
||
" will cause " Ocaml_print_type function to be invoked with the right
|
||
" argument depending on the current mode (visual or not).
|
||
" >>
|
||
"
|
||
" If you find something not matching this behaviour, please signal it.
|
||
"
|
||
" Differences are:
|
||
" - no need for python support
|
||
" + plus : more portable
|
||
" + minus: no more lazy parsing, it looks very fast however
|
||
"
|
||
" - ocamlbuild support, ie.
|
||
" + the plugin finds the _build directory and looks for the
|
||
" corresponding file inside;
|
||
" + if the user decides to change the name of the _build directory thanks
|
||
" to the '-build-dir' option of ocamlbuild, the plugin will manage in
|
||
" most cases to find it out (most cases = if the source file has a unique
|
||
" name among your whole project);
|
||
" + if ocamlbuild is not used, the usual behaviour holds; ie. the .annot
|
||
" file should be in the same directory as the source file;
|
||
" + for vim plugin programmers:
|
||
" the variable 'b:_build_dir' contains the inferred path to the build
|
||
" directory, even if this one is not named '_build'.
|
||
"
|
||
" Bonus :
|
||
" - latin1 accents are handled
|
||
" - lists are handled, even on multiple lines, you don't need the visual mode
|
||
" (the cursor must be on the first bracket)
|
||
" - parenthesized expressions, arrays, and structures (ie. '(...)', '[|...|]',
|
||
" and '{...}') are handled the same way
|
||
|
||
" Copied from Stefano's original plugin :
|
||
" <<
|
||
" .annot ocaml file representation
|
||
"
|
||
" File format (copied verbatim from caml-types.el)
|
||
"
|
||
" file ::= block *
|
||
" block ::= position <SP> position <LF> annotation *
|
||
" position ::= filename <SP> num <SP> num <SP> num
|
||
" annotation ::= keyword open-paren <LF> <SP> <SP> data <LF> close-paren
|
||
"
|
||
" <SP> is a space character (ASCII 0x20)
|
||
" <LF> is a line-feed character (ASCII 0x0A)
|
||
" num is a sequence of decimal digits
|
||
" filename is a string with the lexical conventions of O'Caml
|
||
" open-paren is an open parenthesis (ASCII 0x28)
|
||
" close-paren is a closed parenthesis (ASCII 0x29)
|
||
" data is any sequence of characters where <LF> is always followed by
|
||
" at least two space characters.
|
||
"
|
||
" - in each block, the two positions are respectively the start and the
|
||
" end of the range described by the block.
|
||
" - in a position, the filename is the name of the file, the first num
|
||
" is the line number, the second num is the offset of the beginning
|
||
" of the line, the third num is the offset of the position itself.
|
||
" - the char number within the line is the difference between the third
|
||
" and second nums.
