如何在可视模式下在外部过滤器命令中使用vim变量？
我正在尝试使代码漂亮的打印机过滤器（例如 perltidy）接受取决于 vim 变量的任意选项。我的目标是将项目特定选项传递给在可视模式下用作过滤器 (:!) 的外部命令。
下面表达了我的意图（最后一行有问题）：
" set b:perltidy_options based on dirname of the currently edited file
function! SetProjectVars()
if match(expand("%:p:h"), "/project-foo/") >= 0
let b:perltidy_options = "--profile=$HOME/.perltidyrc-foo --quiet"
elseif match(expand("%:p:h"), "/project-bar/") >= 0
let b:perltidy_options = "--profile=$HOME/.perltidyrc-bar --quiet"
else
let b:perltidy_options = "--quiet"
endif
endfunction
" first set the project specific stuff
autocmd BufRead,BufNewFile * call SetProjectVars()
" then use it
vnoremap ,t :execute "!perltidy " . b:perltidy_options<Enter>
但是，最后一行（vnoremap）在vim中是错误的，因为它扩展为：
:'<,'>execute "!perltidy " . b:perltidy_options
并且执行命令无法接受范围。 但我想要这个：
:execute "'<,'>!perltidy " . b:perltidy_options
我该怎么做？
ps 我的 perltidy 配置为像 unix 过滤器一样工作，我使用 vim 7.3。
I'm trying to make a code pretty printer filter (e.g. perltidy) accept arbitrary options depending on vim variables. My goal is to pass project specific options to an external command used as a filter (:!) in visual mode.
The following expresses my intention (the last line is problematic):
" set b:perltidy_options based on dirname of the currently edited file
function! SetProjectVars()
if match(expand("%:p:h"), "/project-foo/") >= 0
let b:perltidy_options = "--profile=$HOME/.perltidyrc-foo --quiet"
elseif match(expand("%:p:h"), "/project-bar/") >= 0
let b:perltidy_options = "--profile=$HOME/.perltidyrc-bar --quiet"
else
let b:perltidy_options = "--quiet"
endif
endfunction
" first set the project specific stuff
autocmd BufRead,BufNewFile * call SetProjectVars()
" then use it
vnoremap ,t :execute "!perltidy " . b:perltidy_options<Enter>
However, the last line (vnoremap) is an error in vim, because it expands to:
:'<,'>execute "!perltidy " . b:perltidy_options
and the execute command cannot accept a range.
But I'd like to have this:
:execute "'<,'>!perltidy " . b:perltidy_options
How can I do this?
p.s. My perltidy is configured to act like a unix filter and I use vim 7.3.

您可以使用
e getcmdline()来保留命令行内容：，但在这种情况下，我建议更简单的
< Cr>=消除了对:execute的需要：You can use
<C-\>eandgetcmdline()to preserve command-line contents:, but in this case I would suggest simpler
<C-r>=which purges out the need for:execute:如果您想在命令（ex）模式下删除范围，
CRL-u 就会做到这一点。
变成
:h c_CTRL-u
快乐 vimming,

If you ever want to get rid of a range in command (ex) mode,
CRL-u will do just that.
becomes
:h c_CTRL-u
Happy vimming,
