Vim function to make g++ errors readable.
Posted Mon, 14 Jan 2008
If you've ever used templates in C++, you've probably gone blind trying to read the compiler errors.
grokmatch.hpp:7: error: 'typedef class std::map<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::less<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<const std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > GrokMatch<boost::xpressive::basic_regex<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >::match_map_type' is privateI'm supposed to read all that crap? Especially since 99% of the data isn't useful in most cases. The following vim script sanitizes this output:
function! GPPErrorFilter()
silent! %s/->/ARROW/g
while search("<", "wc")
let l:line = getline(".")
let l:col = col(".")
let l:char = l:line[l:col - 1]
if l:char == "<"
normal d%
else
break
endif
endwhile
silent! %s/ARROW/->/g
silent %!awk '/: In/ { print "---------------"; print }; \!/: In/ {print }'
endfunction
If I dump the output of make to a file (including stderr), and run the function while in vim, using ':call GPPErrorFilter()', the output turns into this:
g++ -g -I/usr/local/include -c -o main.o main.cpp --------------- grokmatch.hpp: In function 'int main(int, char**)': grokmatch.hpp:7: error: 'typedef class std::map GrokMatch::match_map_type' is private main.cpp:43: error: within this context make: *** [main.o] Error 1So much better... Now i know I'm clearly trying to access a private typedef. Sanity++
