" Open a scratch buffer (a buffer without a file).
"   TScratch  ... use split window
"   TScratch! ... use the whole frame
" This command takes an (inner) dictionary as optional argument.

" :display: :TBrowseOutput COMMAND
" Ever wondered how to efficiently browse the output of a command 
" without redirecting it to a file? This command takes a command as 
" argument and presents the output via |tlib#input#List()| so that you 
" can easily search for a keyword (e.g. the name of a variable or 
" function) and the like.
"
" If you press enter, the selected line will be copied to the command 
" line. Press ESC to cancel browsing.
"
" EXAMPLES: >
"   TBrowseOutput 20verb TeaseTheCulprit
command! -nargs=1 -complete=command TBrowseOutput call tlib#cmd#BrowseOutput(<q-args>)


" :display: :TBrowseScriptnames
" List all sourced script names (the output of ':scriptnames').
"
" When you press enter, the selected script will be opened in the current
" window. Press ESC to cancel.
"
" EXAMPLES: >
"   TBrowseScriptnames 
command! -nargs=0 TBrowseScriptnames call tlib#cmd#TBrowseScriptnames()


" :display: :Texecqfl CMD
" Run CMD and display the quickfix list.
command! -nargs=1 Texecqfl <args> | call tlib#qfl#QflList(getqflist())

" Run CMD and display the quickfix list.
command! -nargs=1 Texecloc <args> | call tlib#qfl#QflList(getloclist(0))


" :display: :Tlibtrace GUARD, VAR1, VAR2...
" Do nothing unless |tlib#trace#Enable()| was called.
" 
" When |:Tlibtraceset| or |tlib#trace#Enable()| were called:
"
" If GUARD is a number that evaluates to true or if it is a string that 
" matches a |regexp|, which was added using Tlibtrace! (with '!'), 
" display the values of VAR1, VAR2 ...
command! -nargs=+ -bang Tlibtrace :


" :Tlibtraceset[!] [--file=FILE] +RX1 -RX2...
" If |tlib#trace#Enable()| was called: With the optional <bang>, users 
" can add and remove GUARDs (actually a |regexp|) that should be traced.
"
" If no `+` or `-` is prepended, assume `+`.
"
" With the optional bang '!', reset any options.
command! -nargs=+ -bang Tlibtraceset call tlib#trace#Set(tlib#arg#GetOpts([<f-args>], {'short': 0}), !empty("<bang>"))
