How do I run a vim script that alters the current buffer? -

-

i'm trying write beautify.vim script makes c-like code adhere standard can read.

my file contains substitution commands begin %s/...

however, when try run script file open, in manner :source beautify.vim, or :runtime beautify.vim, runs substitute commands state pattern wasn't found (patterns tested entering them manually , should work).

is there way make vim run commands in context of current buffer?

beautify.vim:

" add spaces before open braces sil! :%s/\%>1c\s\@<!{/ {/g " beautify sil! :%s/for *( *\([^;]*\) *; *\([^;]*\) *; *\([^;]*\) *)/for (\1; \2; \3)/ " add spaces after commas sil! :%s/,\s\@!/, /g

in tests first :s command should match (it matches when applied manually).

i wrote similar beautifier script implemented in think more flexible way; plus, tried come mechanism avoid substituting stuff within strings.

" {{{ regex silly beautifier (avoids strings, works ranges) function! foo_sillyregexbeautifier(start, end)      let = a:start     while <= a:end         let line = getline(i)          " ignore preprocessor directives         if match(line, '^\s*#') == 0             let += 1             continue         endif          " ignore content of strings, splitting @ double quotes characters not          " preceded escape characters         let chunks = split(line, '\(\([^\\]\|^\)\\\(\\\\\)*\)\@<!"', 1)          let c = 0         c in range(0, len(chunks), 2)              let chunk = chunks[c]             " add whitespace in couples             let chunk = substitute(chunk, '[?({\[,]', '\0 ', 'g')             let chunk = substitute(chunk, '[?)}\]]', ' \0', 'g')              " continue calling substitute() on chunk ,              " reassigning             " ...              let chunks[c] = chunk         endfor          let line = join(chunks, '"')          " remove spaces @ end of line         let line = substitute(line, '\s\+$', '', '')          call setline(i, line)          let += 1     endw endfunction " }}}

then define mapping affects whole file in normal mode, , selected lines in visual mode. when have formatted parts of file don't want touch.

nnoremap ,bf :call foo_sillyregexbeautifier(0, line('$'))<cr> vnoremap ,bf :call foo_sillyregexbeautifier(line("'<"), line("'>"))<cr>

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
