Is there a way to use folds or some other Vim-script black magic to hide license blocks at the top of files? I don't like that they take up such a large section of my editing pane; I like to get a sense for what a file is doing when I first open it, rather than a face-full of boilerplate.
Try this in an autocommand.
function! FoldCopyright
if !exists( "b:foldedCopyright" )
let b:foldedCopyright = 1
1,15fold
endif
endfunction
Adjust the range on line 4 appropriately. In the worst case where the copyright starts in different places and is a variable length this pattern should do:
1,/Beginning of copyright/;/End of copyright/
It depends on whether there's a consistent form to the licence block and what language you're programming in. For example, python tends to use a 'foldexpr' to define folding, so to add this you'd have to replace the existing function with a new one (or get rid of the existing folding). I believe the default in C is to use manual folding (although it's possible that I configured it that way myself: I can't remember), so this is much easier to add extra folding.
With a simple GPL copyright message like the one at the end of this post, you could set foldmethod to manual and have a simple function that creates a fold. It all depends on the form of the copyright and how important it is for you to maintain the existing folding. I'm afraid I'd need a bit more detail to give a more useful answer. Anyway, here's an example script that could be used to fold the copyright notice at the end of this post:
function! CreateCopyrightFold()
let InCopyright = 0
set foldmethod=manual
for Line in range(1,line('$'))
let LineContents = getline(Line)
if LineContents !~ "^#"
if InCopyright
let CopyrightEnd = Line - 1
exe CopyrightStart . ',' . CopyrightEnd . 'fold'
endif
break
elseif LineContents =~ "Copyright"
let InCopyright = 1
let CopyrightStart = Line
endif
endfor
endfunction
au BufRead *.py call CreateCopyrightFold()
