这两天在用vim写c的时候发现一个奇怪的问题

当用vimim 输入完中文回到英文时，我用imap设定的 括号配对无法使用了

仔细研究发现，当使用过 vimim 后，键盘上只有F1-F-12 这几个键的imap还生效，其余

自己设定的imap都被清空

于是查找原因

首先想到的就是imap问题，于是查看不同情况下的imap

在没有调用vimim时 敲:imap 查看得

i            rintf("\n");

i            :!gcc %

i  VimIM * 12_ChineseMode()

i  VimimOneKey * g:vimim_onekey()

i          * :wa

i            78i-o

i          * :ConqueTermVSplit bash

i

i

i

i

i

i

i    * 12_VimIMSwitch()

i           VimIM

i           VimimOneKey

i  (             ()i

i  )             =ClosePair(')')

i  p

i  {             {}O

i  }             =ClosePair('}')

打开vimim,再查看imap ，如下

i          * 12_vimim_backspace()

i            rintf("\n");

i            :!gcc %

i  VimIM * 12_ChineseMode()

i  VimimOneKey * g:vimim_onekey()

i  }           * 12_vimim_chinese_punctuation_map("}")

i  ~           * 12_vimim_chinese_punctuation_map("~")

在关闭vimim后再查看imap ，发现

i            rintf("\n");

i            :!gcc %

i  VimIM * 12_ChineseMode()

i  VimimOneKey * g:vimim_onekey()

i          * :wa

i            78i-o

i          * :ConqueTermVSplit bash

i

i

i

i

i

i

i    * 12_VimIMSwitch()

i           VimIM

i           VimimOneKey

通过上面三个的比较，可以明白是怎么回事了，当启用vimim后，vimim 会通过imap 对

按键进行映射，对字母进行调用 匹配的函数， 对标点、符号则把半角换成全角。当

vimim被关闭后，程序调用函数把上面的映射清除，于是原先自己设定的imap就没有了。

于是想通过修改原代码，让它不去改动我需要的一些标点

打开 vimim.vim

首先看到这一段函数，从字面上看它是控制 打开和关闭vimim时执行的动作

function! s:vimim_start()

sil!call s:vimim_plugin_conflict_fix_on()

sil!call s:vimim_i_setting_on()

sil!call s:vimim_super_reset()

sil!call s:vimim_label_on()

sil!call s:vimim_helper_mapping_on()

set noruler

highlight! link Cursor CursorIM

endfunction

function! g:vimim_stop()

sil!call s:vimim_i_setting_off()

sil!call s:vimim_super_reset()

sil!call s:vimim_i_map_off()

sil!call s:vimim_plugin_conflict_fix_off()

sil!call s:vimim_chinesemode_mapping()

sil!call s:vimim_onekey_mapping()

sil!call s:vimim_restore_skin()

endfunction

一直没有找到设定imap的函数在哪，把start中的函数挨个注释都没找到。

但发现stop函数中的s:vimim_i_map_off()，是控制是否清空imap功能的，于是去看该

函数

function! s:vimim_i_map_off()

let recycles = range(0,9) + s:valid_keys

if s:chinese_input_mode !~ 'dynamic' && empty(s:vimim_latex_suite)

let recycles += s:AZ_list

endif

let recycles += keys(s:evils) + keys(s:punctuations)

let recycles += ['','','','']

for _ in recycles

if len(maparg(_, 'i')) > 0

sil!exe 'iunmap '. _

endif

endfor

endfunction

从中发现了punctuations ，搜索之，发现要找的东西了

function! s:vimim_dictionary_punctuation()

let s:punctuations = {}

let s:punctuations['@'] = s:space

let s:punctuations[':'] = s:colon

let s:punctuations['['] = s:left

let s:punctuations[']'] = s:right

let s:punctuations['#'] = '＃'

let s:punctuations['&'] = '＆'

let s:punctuations['%'] = '％'

let s:punctuations['$'] = '￥'

let s:punctuations['!'] = '！'

let s:punctuations['~'] = '～'

let s:punctuations['('] = '('

let s:punctuations[')'] = ')'

let s:punctuations['{'] = '〖'

let s:punctuations['}'] = '〗'

let s:punctuations['^'] = '……'

let s:punctuations['_'] = '——'

let s:punctuations['

let s:punctuations['>'] = '》'

let s:punctuations['+'] = "＋"

let s:punctuations['-'] = '－'

let s:punctuations['='] = '＝'

let s:punctuations[';'] = '；'

let s:punctuations[','] = '，'

let s:punctuations['.'] = '。'

let s:punctuations['?'] = '？'

let s:punctuations['*'] = '﹡'

let s:evils = {}

if empty(s:vimim_backslash_close_pinyin)

let s:evils['\'] = '、'

endif

if empty(s:vimim_latex_suite)

let s:evils["'"] = '‘’'

let s:evils['"'] = '“”'

endif

endfunction

这就是那个把标点符号从半角换成全角的函数

于是……把不能让它imap的 注释掉

let s:punctuations = {}

"    let s:punctuations['@'] = s:space

"    let s:punctuations[':'] = s:colon

"    let s:punctuations['['] = s:left

"    let s:punctuations[']'] = s:right

"    let s:punctuations['#'] = '＃'

"    let s:punctuations['&'] = '＆'

"    let s:punctuations['%'] = '％'

"    let s:punctuations['$'] = '￥'

"    let s:punctuations['!'] = '！'

let s:punctuations['~'] = '～'

"    let s:punctuations['('] = '('

"    let s:punctuations[')'] = ')'

"    let s:punctuations['{'] = '〖'

"    let s:punctuations['}'] = '〗'

let s:punctuations['^'] = '……'

let s:punctuations['_'] = '——'

"    let s:punctuations['

"    let s:punctuations['>'] = '》'

let s:punctuations['+'] = "＋"

let s:punctuations['-'] = '－'

"    let s:punctuations['='] = '＝'

"    let s:punctuations[';'] = '；'

let s:punctuations[','] = '，'

let s:punctuations['.'] = '。'

"    let s:punctuations['?'] = '？'

"    let s:punctuations['*'] = '﹡'

ok,保存退出，去试试效果  perfect啊

现在写c就更爽了，括号配对，中文输入插件 ，哈哈哈……
