scripting - Vim script: Buffer/CheatSheet Toggle -

-

i want make vim cheat sheet plugin. it's real simple:

  • i want toggle cheatsheets. vertsplit toggle, taglist or nerdtree.
  • i want cheatsheet filetype specific. toggle c++ cheatsheet when have opened .cpp file.
  • i want cheatsheet horizontally split. shows 2 files, syntax cheat sheet , snippet trigger cheat sheet.

i have collection of these cheatsheets, in vimhelp format, have manually open them.

i haven't done vim scripting, imagine simple put together. i'm sorta sick of googling unrelated codesnippets, i'm asking here is:

  1. could give me short sum-up of need learn in regards vim scripting piece together. have hard time finding how toggle buffer window.

  2. if know intro tutorials covers material need , running, please provide link.

tx,

aktivb

the function below may not want, , haven't tested it, should give ideas.

the main idea function reads filetype of current buffer (you can test typing :echo &ft) , sets path of appropriate cheat sheat. if exists, path opened (read-only , non-modifiable) in split window. can call function way wish, example mapping {f5} key shown.

i'm not sure toggling possibilities (is easier closing split window?) @ bufloaded() function, returns whether or not given file being accessed.

function! load_cheat_sheet()     let l:ft = &ft      if l:ft == 'html'         let l:path = 'path/to/html/cheat/sheet'     elseif l:ft == 'c'         let l:path = 'path/to/c/cheat/sheet'     elseif l:ft == 'tex'         let l:path = 'path/to/tex/cheat/sheet'     endif      if l:path != '' && filereadable(l:path)         execute ':split +setlocal\ noma\ ro ' l:path     endif endfunction  map <f5> :call load_cheat_sheet()<cr>

hope helps. shout if unclear, or want know more.

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.

razor - Is this a bug in WebMatrix PageData? -

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...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
