Ich habe eine Funktion, die viel Text in den aktuellen VIM-Puffer verschiebt und ausgibt, und wenn ich ihn ausführe, ist es etwas beunruhigend zu sehen, was alles mit blendender Geschwindigkeit passiert.
Wie kann ich den Bildschirm einfrieren, bis die Funktion abgeschlossen ist?
Hier ist die fragliche Funktion:
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
