8" Only do this when not done yet for this buffer.

13" Start with plain TeX.  This will also define b:did_ftplugin .
14source $VIMRUNTIME/ftplugin/plaintex.vim

16" Avoid problems if running in 'compatible' mode.
17let s:save_cpo = &cpo
18set cpo&vim

20let b:undo_ftplugin .= "| setl inex<"

22" Allow "[d" to be used to find a macro definition:
23" Recognize plain TeX \def as well as LaTeX \newcommand and \renewcommand .
24" I may as well add the AMS-LaTeX DeclareMathOperator as well.
25let &l:define .= '\|\\\(re\)\=new\(boolean\|command\|counter\|environment\|font'
26	\ . '\|if\|length\|savebox\|theorem\(style\)\=\)\s*\*\=\s*{\='
27	\ . '\|DeclareMathOperator\s*{\=\s*'
28
29" Tell Vim how to recognize LaTeX \include{foo} and plain \input bar :
30let &l:include .= '\|\\include{'
31" On some file systems, "{" and "}" are inluded in 'isfname'.  In case the
32" TeX file has \include{fname} (LaTeX only), strip everything except "fname".
33let &l:includeexpr = "substitute(v:fname, '^.\\{-}{\\|}.*', '', 'g')"
34
35" The following lines enable the macros/matchit.vim plugin for
36" extended matching with the % key.
37" ftplugin/plaintex.vim already defines b:match_skip and b:match_ignorecase
38" and matches \(, \), \[, \], \{, and \} .
