Welcome to the NERDTree Wiki!
Feel free to contribute any tips you have learned while using NERDTree.
I noticed that some of the snippets used if &buftype != 'quickfix' lalala, but for some reason, this doesn't work. Even :set buftype? after starting a quickfix (vim -q errorfile), it didn't return a value.
So I nosed around and found this construct, which gets us a list of command line options -- and the next line, which is 0 or 1 depending on whether -q was thrown on the command line:
let s:options = split(system("ps -o command= -p " . getpid()))
let s:q_opt = count(s:options, '-q')
So if you start vim with any of the usual snippets of code, but enter quickfix mode: vim -q errorfile, you wind up with:
- the error file as requested
- NERDTree started, which for quickfix operations is less desirable
- the cursor in the NERDTree, which is really less than desirable
- the first error on the list missing. Sure, you can use
:ccto get at it, but fingers are tired.
The code to end this misery is:
autocmd StdinReadPre * let s:std_in=1
" kludgy way of getting the command line:
let s:options = split(system("ps -o command= -p " . getpid()))
let s:q_opt = count(s:options, '-q')
" Start NERDTree. If a file is specified, move the cursor to its window.
" Do not start NERDTree if this is a quickfix operation.
autocmd VimEnter * if s:q_opt == 0 | NERDTree | endif | if argc() > 0 || exists("s:std_in") | wincmd p | endif
Vimscripts: check if item in list For the count(g:foo, a:bar) idea
Is it possible to access vim's command-line arguments in vimscript? For the split(system("ps... idea for getting at command line options
