Asciidoc folding for Vim
I just learned about the ability to fold in Vim. For mere mortals, it means hiding parts of the file.
Here is a code to put in your
.vimrc to allow folding for Asciidoc(tor) files.
It folds asciidoc files at section boundaries and use nested folds for subsections.
"" Fold Asciidoc files at sections and using nested folds for subsections " compute the folding level function! AsciidocLevel() if getline(v:lnum) =~ '^== .*$' return ">1" endif if getline(v:lnum) =~ '^=== .*$' return ">2" endif if getline(v:lnum) =~ '^==== .*$' return ">3" endif if getline(v:lnum) =~ '^===== .*$' return ">4" endif if getline(v:lnum) =~ '^====== .*$' return ">5" endif if getline(v:lnum) =~ '^======= .*$' return ">6" endif return "=" endfunction " run the folding level method when asciidoc is here autocmd Syntax asciidoc setlocal foldexpr=AsciidocLevel() " enable folding method: expression on asciidoc autocmd Syntax asciidoc setlocal foldmethod=expr " start with text unfolded all the way autocmd BufRead *.adoc normal zR autocmd BufRead *.asciidoc normal zR " TODO following does not work as folding is lost up reloading " autocmd Syntax asciidoc normal zR
I'm sure it can be improved - I'd love to fold blocks as well - but that's a start.
Here are a few commands to remember to fold in Vim
zo: open a fold at cursor
zO: open all folds down at cursor
zc: close a fold at cursor
zC: close all levels of folds at cursor
zA: toggle fold
zm: close fold by one level across the file
zM: close all folds across the file
zr: open fold by one level across the file
zR: open all folds across the file
zk: move to next / previous fold
]z: go to begining / end of the fold
