解决imap被vimIM和谐掉的问题

 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  <F9>          rintf("\n");
i  <F3>          <Esc>:!gcc % <CR>
i  <Plug>VimIM * <SNR>12_ChineseMode()
i  <Plug>VimimOneKey * g:vimim_onekey()
i  <F2>        * <Esc>:w<CR>a
i  <F8>          <CR><Esc>78i-<Esc>o
i  <F4>        * <Esc>:ConqueTermVSplit bash<CR>
i  <C-F>         <C-X><C-F>
i  <C-K>         <C-X><C-K>

i  (             ()<Esc>i

i  p             <F9><Space>
i  {             {<CR>}<Esc>O
i  }             <C-R>=ClosePair('}')<CR>

打开vimim,再查看imap ，如下

在关闭vimim后再查看imap ，发现
i  <F9>          rintf("\n");
i  <F3>          <Esc>:!gcc % <CR>
i  <Plug>VimIM * <SNR>12_ChineseMode()
i  <Plug>VimimOneKey * g:vimim_onekey()

i  <C-\>         <Plug>VimIM
i  <C-^>         <Plug>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 += ['<Esc>','<CR>','<BS>','<Space>']
    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……
