Eu estou tentando usar ctags com VIM, e eu sou um novato para ambos. A fim de testar a extensão em que ctags poderia ser Eu útil decidiu colocá-lo através de um teste muito simples, ou seja, para analisar os cabeçalhos em / usr / include para que eu pudesse autocomplete algumas funções básicas.
Quando eu executar o comando
ctags --c++-kinds=+p --fields=+iaS -f ~/.tags/tags /usr/include/*.h
Então, a saída impressões

tão claramente CTags perdeu algumas funções muito óbvias como fopen, ainda que incluía funções como fclose. Existe alguma opção que eu estou faltando quando eu estou analisando com ctags?
Solução
Adicionar um -I__wur para comandar seus ctags e você vai obter o resultado que você está depois.
__wur é uma macro para __attribute__ ((__warn_unused_result__))
Para uma thurough explicação mais, consulte:
http://sourceforge.net/mailarchive/message .php? msg_name = 48A7FF60.9080609% 40sina.com
Outras dicas
Apenas algumas dicas para que você pode obter um arquivo de tags mais específico:
# First make sure apt-file is install and then do:
$ sudo apt-file update
# set up tags for libc, the standard C library
$ apt-file list libc6-dev | grep -o '/usr/include/.*\.h'> ~/.vim/tags/libc6-filelist
$ ctags --sort=foldcase --c++-kinds=+p --fields=+iaS --extra=+q -I./libc6-ignore -f ~/.vim/tags/libc6 -L ~/.vim/tags/libc6-filelist
O conteúdo do arquivo libc6-ignoram são:
__attribute__
__attribute_deprecated__
__attribute_format_arg__
__attribute_format_strfmon__
__attribute_malloc__
__attribute_noinline__
__attribute_pure__
__attribute_used__
__attribute_warn_unused_result__
__wur
__THROW
__nonnull+
Eu suponho que você está usando isso com o vim e o plug-in OmniCppComplete?
Apenas mais dicas, HTH.
1 . Sob máquina Ubuntu, pode-se executar dpkg -L libc6-dev |grep -o '/usr/include/.*h' > ~/.vim/tags/libc6-dev_files para obter cabeçalhos no GNU C Library.
2 . Utilize os comandos abaixo para gerar o arquivo ctags mais específico.
# mkdir se necessário.
cd ~/.vim/tags
# Get mais fichas ser ignorado usando grep.
grep -oe '__attribute\w*__' libc6-dev_tags |sort -u > libc6-dev_ignore-tokens
echo __THROW >> libc6-dev_ignore-tokens
echo __wur >> libc6-dev_ignore-tokens
# Gerar arquivo ctags. Consulte ctags página de manual para mais detalhes.
ctags --c++-kinds=+px --fields=+iaS --extra=+q -I @./libc6-dev_ignore-tokens -L libc6-dev_files -f libc6-dev_tags
3 . Adicione este arquivo de tags para seu caminho de etiquetas inicial, ou seja, colocar em algum lugar set tags+=~/.vim/tags/libc6-dev_tags em seu arquivo .vimrc.
Mesmo problema. Resolvidas com a opção -I. Xadrezes este local para informações: http://ctags.sourceforge.net/ctags.html#OPTIONS
Observe um par de "pegadinha do". Primeiro, ao especificar -I com um arquivo que contém a lista de ignorados, ele precisa ser seguido imediatamente por um @ ou a. ou um / ou uma letra de unidade (se no windows). Passei horas usando -I ~ / sem sucesso. A mesma coisa com -I / home / username / funcionou como um encanto.
Em segundo lugar, garantir a utilização de várias linhas de análise (--fields = + S). Isso já é indicado como uma opção usada pelo OP neste segmento, mas queria indicá-lo novamente.
Obrigado a todos mais para as pontas impressionantes!
