Naturally, as a developer I learn new awesome things almost every day.
I thought it might be a good idea to keep track of all those small Ah-Ha!
moments and release a snippets post every month.
Global .gitignore
When I wanted to contribute code to
Pelican I naively added
.ropeproject to that repo's .gitignore file. As a result, I was told in
the codereview that I should not pollute other project's .gitignore files
with unrelated stuff but rather use a global .gitignore file instead. How
could I not know about this until now?!?
Just add the following code to your .gitconfig:
[core]
excludesfile = $HOME/.gitignore_global
Then create the .gitignore_global file and put stuff inside that your
editors of choice might produce.
Better Omni Completion in Vim
So I finally got the hjkl keys for movement into my muscle memory. Now it
annoys me that I have to use the arrow keys when I want to browse through the
various options that the code completion suggests. There is a vimbit for that:
set completeopt=longest,menuone
" found here: http://stackoverflow.com/a/2170800/70778
function! OmniPopup(action)
if pumvisible()
if a:action == 'j'
return "\<C-N>"
elseif a:action == 'k'
return "\<C-P>"
endif
endif
return a:action
endfunction
inoremap <silent><C-j> <C-R>=OmniPopup('j')<CR>
inoremap <silent><C-k> <C-R>=OmniPopup('k')<CR>
Vimbits
Speaking of vimbits: vimbits.com recently flew through
my Twitter stream. I spent an hour there. As a result my .vimrc just
exploded with all kinds of awesomeness.
Showing git branch in prompt
I thought that I was typing git branch way too often (actually I type
git br, of course).
export PS1='\w\[\033[31m\]$(__git_ps1 "(%s)") \[\033[01;34m\]$\[\033[00m\] '
Hint: In order for this to work, you need to install git via Homebrew on OSX.
There are comments.
