我有一些命令用于压缩文件保存,post保存解压缩(只是开头的缩进)。我遇到困难的一件事是我不希望将命令添加到历史记录中。既不是命令也不是光标位置等
我认为我要做的是在预写时关闭viminfo
,然后在写后重新打开它。但我似乎无法弄明白。这是我正在使用的功能:
function! s:CompressIndent()
augroup CompressIndent
autocmd!
" Befor writing, change 4 spaces (and single tabs) into 2 spaces
autocmd BufWritePre * set viminfo="NONE" " Turn off 'history' before making the pre-write substitutions
autocmd BufWritePre * %substitute/^\( \+\)\1/\1/e " Halve the number of spaces of indentation
autocmd BufWritePre * set tabstop=2 " Make sure that tabs = 2 spaces before re-tabbing
autocmd BufWritePre * retab " Turn tabs into two spaces
" When opening a file (and after writing the file) turn 2 spaces into (and 4 tabs) into 4 spaces
autocmd BufReadPost,BufWritePost * set tabstop=4 " Make sure to display in 4 tabs
autocmd BufReadPost,BufWritePost * %substitute/^ \+/&&/e " Double the number of spaces of indentation on Reading and writing
autocmd BufReadPost,BufWritePost * set viminfo='20,\"200 " Turn back on history
augroup END
endfunction
我已尝试set viminfo="NONE"
和set viminfo=""
。似乎都没有效果。
任何帮助将不胜感激!
谢谢!
修改
这就是我现在使用它的地方,但我仍然没有完全使用它(现在缩进已经破坏,但histdel()也不能正常工作。保存文件后,光标移动到一个全新的位置和撤消历史已经分支或奇怪的事情:
function! s:CompressIndent()
augroup CompressIndent
autocmd!
" Befor writing, change 4 spaces (and single tabs) into 2 spaces
autocmd BufWritePre * call s:SpaceSubstitution("2") " Halve the number of spaces of indentation
autocmd BufWritePre * set tabstop=2 " Make sure that tabs = 2 spaces before re-tabbing
autocmd BufWritePre * retab " Turn tabs into two spaces
" When opening a file (and after writing the file) turn 2 spaces into (and 4 tabs) into 4 spaces
autocmd BufReadPost,BufWritePost * set tabstop=4 " Make sure to display in 4 tabs
autocmd BufReadPost,BufWritePost * call s:SpaceSubstitution("4") " Double the number of spaces of indentation on Reading and writing
augroup END
endfunction
command! -n=0 -bar CompressIndent :call s:CompressIndent()
function! s:SpaceSubstitution(toSpaces)
if a:toSpaces == "2"
%substitute/^\( \+\)\1/\1/e
else
%substitute/^ \+/&&/e
endif
call histdel('search', -1)
endfunction

Vim有四个用于操作历史记录的函数,:h history-functions
为您提供了一个列表和简短描述。在这四个中,您需要的是:
histdel()
您可以在:h histdel()
中阅读。

操纵'viminfo'
太棒了,无法在这里挥舞。 :autocmd
执行的命令不会添加到命令历史记录中。
我唯一看到的是:substitute
污染了搜索历史和当前的搜索模式。通过将命令移动到:function
并从autocmd调用该命令,可以避免很多事情。请参阅:help function-search-undo
。
在函数结束时,您唯一需要做的就是从历史记录中删除搜索模式:
:call histdel('search', -1)
编辑:要保持当前光标位置,请使用以下内容包裹:substitute
:
let l:save_view = winsaveview()
%substitute/...
call winrestview(l:save_view)
