У меня есть функция, которая выполняет много операций по перемещению и выводу текста в текущий буфер vim, и когда я ее запускаю, то, что происходит со скоростью ослепления, немного сбивает с толку.
Как я могу заморозить экран, пока функция не будет выполнена?
Вот эта функция:
function! MakeChoices()
:let save_view = winsaveview()
let start = line('.')
"Locate previous *choice. (b=backwards, W=nowrap, n=doNot move cursor)
let choiceStartLine = search('^*choice', 'bW')
if !choiceStartLine
echo "No *choice found. (*choice must not be indented. This is to avoid finding *choice blocks nested in another *choice block.)"
return -1
endif
"return getline(target_line_num, target_line_num+4)
"Locate end of *choice block
"echo getline(choiceStartLine, choiceStartLine+2)
let choiceEndLine = search('^\S.*', 'W') "End is first line that starts with non-whitespace
"If above search fails, might be at bottom of buffer
if choiceEndLine == 0
let choiceEndLine = search('^$', 'W') "End is first empty line
endif
"Now go back up to the last *goto
let choiceEndLine = search('*goto', 'bW')
"Get the entire *choice block and put it in gotoBlock
let gotoBlock = getline(choiceStartLine, choiceEndLine)
"Make labelArray (contains all labels to goto)
let labelArray = []
for cur in gotoBlock
if match(cur, '*goto') != -1
"echo 'cur: '.cur
let curParsed = matchlist(cur, '*goto \(\S\+\)')
"echo curParsed
if len(curParsed) > 1
let curLabel = curParsed[1]
else
echo 'ERROR: Bad *goto ('.cur.')'
return -1
endif
call add(labelArray, curLabel)
endif
endfor
"Restore window to what it looked like (in case the searches scrolled
"it)
call winrestview(save_view)
"Make newline after choice block if needed
if strlen(getline(choiceEndLine+1)) > 0
echo 'big line: '.getline(choiceEndLine+1)
call cursor(choiceEndLine, 1)
put=''
endif
call cursor(choiceEndLine+1, 1)
"Put the new label blocks
let skippedLabels = ''
let numNewLabels = 0
for cur in labelArray
if !search('*label '.cur, 'wn')
let numNewLabels += 1
put='*label '.cur
put='[This option is yet to be written.]'
put=''
else
let skippedLabels .= cur.' '
endif
endfor
"Remove trailing blank lines (Up to a point)
let nextlines = getline(line('.')+1, line('.')+3)
if len(nextlines) == 3
if nextlines[0] == '' && nextlines[1] == '' && nextlines[2] == ''
normal "_3dd
elseif nextlines[0] == '' && nextlines[1] == ''
normal "_2dd
elseif nextlines[0] == ''
normal "_dd
endif
endif
"Move to first label's text (use ctrl-v ctrl-m to input the <CR> at
"end)
if numNewLabels != 0
call cursor(choiceEndLine, 1)
normal /\[This option is yet to be written.\]
let @/='\[This option is yet to be written\.\]'
endif
"Print status message
if len(skippedLabels) > 0
echo 'Skipped: '.skippedLabels
else
echo 'New labels created: '.numNewLabels
endif
endfunction
:set lazyredraw
