The stock C++ indent will indent namespaces, which I find annoying, so this will avoid that indent.
(NOTE: There's a more up to date version of this in the General C++ Settings section.)
Finally! Vim's decision to add a 'shiftwidth' to everything I type when I'm inside a
namespace is thoroughly annoying and there appears to be no "standard" way to fix this in Vim aside from writing your own function for use in the 'indentexpr' option.
Well I finally got around to writing this up and, while extremely crude, it appears to work alright. You'll find the function definition below as well as in the General C++ Settings section.
" Fix up indent issues - I can't stand wasting an indent because " I'm in a namespace. If you don't like this then just comment " this line out. setlocal indentexpr=GetCppIndentNoNamespace(v:lnum) " " GetCppIndentNoNamespace() " " This little function calculates the indent level for C++ and " treats the namespace differently than usual - we ignore it. The " indent level is the for a given line is the same as it would " be were the namespace not event there. " " This function is rather crude but it works. " function! GetCppIndentNoNamespace(lnum) let nsLineNum = search('^\s*\\s\+\S\+', 'bnW') if nsLineNum == 0 return cindent(a:lnum) else let incomment = 0 for n in range(nsLineNum + 1, a:lnum - 1) let cline = getline(n) if cline =~ '^\s*/\*' let incomment = 1 elseif cline =~ '^.*\*/' let incomment = 0 elseif incomment == 0 if cline =~ '^\s*\S\+' return cindent(a:lnum) endif endif endfor return cindent(nsLineNum) endif endfunction
