#38 Sometimes doesn't unindent with a \end

[Anonymous]

For a file like
\begin{test}
foo\end{test}
bar
After the indent, it should be like
\begin{test}
foo\end{test}
bar
But when I use the automatic indent, it becomes
\begin{ŧest}
foo\end{test}
bar
After some experiment, I found out that \end were ignored every time there is other things that spaces and tabs before them on the line.
Looking at the source code of the file indent/tex.vim, I found that it was about the line 180 that reads
if cline =~ '^\s*\\end' && cline !~ g:tex_noindent_env
I changed it on my computer to
if cline =~ '^\s*\\end' && cline !~ g:tex_noindent_env
And it fixed the bug

Ok, my fix doesn't work, I know understand why the '^\s*' was there but I have another fix.
I watch the previous line. If it contains a '\\end' and no '\\end' starting a line, it unindent.
here is the change
" Subtract a 'shiftwidth' when an environment ends
if cline =~ '^\s*\\end' && cline !~ 'verbatim'
\&& cline !~ 'document'
\&& cline !~ 'comment'

if g:tex_indent_items == 1
" Remove another sw for item-environments
if cline =~ 'itemize\|description\|enumerate\|thebibliography'
let ind = ind - &sw
endif
endif

let ind = ind - &sw
endif

+" Subtract a 'shiftwidth' when an environment ended
+" the previous line but the shifwidth wasn't
+" applied because it didn't begin the line
+if line =~ '\\end' && line !~ '^\s*\\end'
+ \&& line !~ 'verbatim'
+ \&& line !~ 'document'
+ \&& line !~ 'comment'
+
+ if g:tex_indent_items == 1
+ " Remove another sw for item-environments
+ if line =~ 'itemize\|description\|enumerate\|thebibliography'
+ let ind = ind - &sw
+ endif
+ endif
+
+ let ind = ind - &sw
+endif
