terminal - How to "highlight" using text in Vim? -


these 3 lines of vim script "highlights" instances of todo in source code placing [[[ , ]]] around it.

:set t_co=1 :highlight braces start=[[[ stop=]]] :call matchadd("braces", "todo")

unfortunately, works in "normal terminals". why have set t_co 1.

can similar achieved in color terminal or in gui? (or in neovim?). extremely useful way of augmenting code meta information.

please keep in mind vim text editor; these display file contents as-is. in order augment code meta information, vim offers:

  • (syntax) highlighting: colors , text attributes bold or italic
  • concealment: hide or condense matches nothing / single character
  • signs (shown in column left of window)

your approach hack misuses definition of raw terminal codes; these meant invisible control sequences interpreted terminal, send visible text.

as you've found out @ :help highlight-args:

there 3 types of terminals highlighting: term      normal terminal (vt100, xterm) cterm     color terminal (ms-dos console, color-xterm, these have "co"           termcap entry) gui       gui

the start= , end= arguments (that hack relies on) supported "normal terminals", not cterm , gui. that's why have :set t_co=1 (i.e. force non-color terminal) work.

because of these downsides (and more: redrawing problems, vertical navigation that's off), recommend drop this, , use 1 of "approved" methods listed above. there many vim users, , seem fine them well.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...
