A simple first-pass fold-expr to handle just hunks:
:set fdm=expr fde=(getline(v:lnum)=~'^@@')?'>1':'='
For a more complex version, you could use
fde=(getline(v:lnum)=~'^Index')?0:(getline(v:lnum)=~'^=\\{3,}')?1:((getline(v:lnum)=~'^@@')?'>2':'=')
(all in one line, in case mailers mung it) which should handle
both multiple hunks and multiple files-to-be-patched in the same
.diff/.patch file.
That breaks down as
- If it begins with 'Index', don't indent it
- If it begins with 3+ "=" signs, start indenting 1 level
- If it starts with "@@", consider it the beginning of a hunk and
start indent-level-2
- Finally, for everything else, treat it as the indentation that
comes from the previous line.
It works at least for some of the SVN diff's I've got floating
around here.
Hope this helps,
