Vim syntax highlighting for WML

[ejls]

Hi!

    I wrote a (basic) Vim syntax file for WML. It is far from perfect, but it is better than nothing. :)

Features
    Highlighting of:

• Standard tags (copied from here)

• Syntax error (basic)

    Sadly, the WML schema project seems abandoned, it would have allowed the recognition of valid keys/tags inside the corresponding parent tag. That is why, I have not included highlighting of standard keys since they would always be highlighted.

Install

• Download vim-wml.tar.gz
• Extract it in your vim syntax directory
  On Linux/Unix:

  Code: Select all

  $ mkdir -p ~/.vim/syntax && tar xzvf vim-wml.tar.gz -C ~/.vim/syntax

• You can enable wml highlighting for the current buffer by typing :set syn=wesml
  To enable it automatically for all .cfg files add the following line to your .vimrc:

  Code: Select all

  au BufNewFile,BufRead *.cfg setf wesml

Notes
    Even if there already exist a syntax highlighting for .cfg files, it is very generic, I tried to match WML syntax more closely. Since the name wml is already taken (Website MetaLanguage), I named the syntax file wesml.
    The most recent version of lua.vim (Vim syntax file for Lua) is using TOP everywhere, this cause some bugs with the definition of Lua blocks. To fix this, I included a file named wmllua.vim which is a 2006 version of lua.vim. This version of Lua highlighting is only for Lua 4.0 to Lua 5.1. Since r52914, Lua 5.2 is included in Wesnoth so the highlighting is not perfect. You may try your local lua.vim file by editing wesml.vim (read the comment before the syn include line).
    Lua code is highlighted only when it is in a String value with the key "code" (even outside a [lua] tag) and when it is the sole attribute of the line. The highlighting of "" in double quoted string, variable ($...|) and formula ($(...)) is rarely (read never) working in Lua code. There is certainly others bugs… I let you hunt them. :)
    I am not a Vim syntax wizard, my goal was to make a (more or less) working syntax file, so the code is not very elegant. However, the file is under 3-clause BSD license, so do not hesitate to improve it. If you have any remark or problem, please let me know (here or on IRC).

    I suppose Vim is not widely used across UMC author, but I hope this will be useful to some of you. :)

I have been using vim so this will be very nice. Thank you!

I'm having trouble with the autocmd setf, here's part of my .vimrc:

Code: Select all

augroup vimrc_autocmds
    au!
    au BufNewFile,BufRead *.cfg setf wesml
    au BufNewFile,BufRead *.cfg echo "setf wesml"
augroup END

The echo happens, regardless of the order of the two au lines. Using :setf wesml or :set syn=wesml after vim has started also works, but the automatic setf doesn't seem to do anything.

maybe it is setting it correctly but then something later is setting it to a different value

Code: Select all

au BufRead,BufNewFile *.cfg set syn=wesml

works for me.
Thank you ejls!

Please commit it to data/tools.
Hopefully it will not fight with the emacs mode there

It works for me now, so I've committed it.
