" 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
