[英]Ignore file extension in bash completion for vim
I wrote a small bash function to provide completion for vim. 我写了一个小的bash函数来为vim提供完成。 The function is the following:
功能如下:
# completion for vim
_vim()
{
local cur prev
COMPREPLY=()
_get_comp_words_by_ref cur prev
case $prev in
-h|--help|-v|--version)
return 0
;;
esac
if [[ "$cur" == -* ]] ; then
local _vopts='-v -e -E -s -d -y -R -Z -m -M -b -l -C'
_vopts="${_vopts} -N -V -D -n -r -r -L -A -H -F -T -u"
_vopts="${_vopts} --noplugin -p -o -O --cmd -c -S -s -w -W"
_vopts="${_vopts} -x -X --remote --remote-silent --remote-wait"
_vopts="${_vopts} --remote-wait-silent --remote-tab --remote-send"
_vopts="${_vopts} --remote-expr --serverlist --servername"
_vopts="${_vopts} --startuptime -i -h --help --version"
COMPREPLY=( $( compgen -W "${_vopts}" \
-- "$cur" ) )
return 0
fi
local _VIM_IGNORE=".pdf:.dvi:.jpg:.pyc:.exe:.tar:.zip:.ps"
FIGNORE="${_VIM_IGNORE}" _filedir
} &&
complete -F _vim vim vi v gv vd
I was trying to have it ignore files with extensions pdf, dvi, etc by defining the _VIM_IGNORE variable and setting FIGNORE to that but that does not work. 我试图让它忽略扩展名为pdf,dvi等的文件,方法是定义_VIM_IGNORE变量并将FIGNORE设置为,但这不起作用。
Any idea how to accomplish this? 知道怎么做到这一点?
Thanks. 谢谢。
I haven't found any documentation, but based on my experiments, it seems that FIGNORE
does not affect the compgen()
/ _filedir()
(which is just a wrapper around the former) processing itself. 我没有找到任何文档,但根据我的实验,似乎
FIGNORE
不影响compgen()
/ _filedir()
(它只是前者的包装)处理本身。 It only affects completions when it is set in the shell from which the completion is triggered (but then globally, which is not what you want). 它只会在触发完成的shell中设置完成时影响完成(但是全局,这不是你想要的)。
I guess you cannot use FIGNORE
in this clever way, and have to explicitly implement a filter of the COMPREPLY
array yourself. 我想你不能以这种聪明的方式使用
FIGNORE
,并且必须自己明确地实现COMPREPLY
数组的过滤器。
Thank to the suggestion by Ingo, this is the solution I have: 感谢Ingo的建议,这是我的解决方案:
function _vim()
{
local cur prev idx ext
COMPREPLY=()
_get_comp_words_by_ref cur prev
case $prev in
-h|--help|-v|--version)
return 0
;;
esac
if [[ "$cur" == -* ]] ; then
local _vopts='-v -e -E -s -d -y -R -Z -m -M -b -l -C'
_vopts="${_vopts} -N -V -D -n -r -r -L -A -H -F -T -u"
_vopts="${_vopts} --noplugin -p -o -O --cmd -c -S -s -w -W"
_vopts="${_vopts} -x -X --remote --remote-silent --remote-wait"
_vopts="${_vopts} --remote-wait-silent --remote-tab --remote-send"
_vopts="${_vopts} --remote-expr --serverlist --servername"
_vopts="${_vopts} --startuptime -i -h --help --version"
COMPREPLY=( $( compgen -W "${_vopts}" \
-- "$cur" ) )
return 0
fi
local _VIM_IGNORE=(pdf xdvi jpg pyc exe tar zip ps)
_filedir
for idx in ${!COMPREPLY[@]}; do
ext=${COMPREPLY[$idx]}
ext=${ext##*.}
for iext in ${_VIM_IGNORE[@]}; do
if test "$ext" = "$iext"; then
unset -v COMPREPLY[$idx]
break
fi
done
done
return 0
}
if the file ends in one of the ignored extensions it deletes it from the array. 如果文件以其中一个被忽略的扩展名结尾,则将其从数组中删除。
