Error management in gulp

#Error management in gulp

Sucking at something is the first step to becoming sorta good at something

No one can assure you, that plugins will run smooth in any circumstances (except for tests - they could), so neither should you convince anyone, that your plugin will never break. Only thing, that you could possibly do (if something gone wrong) - is gracefully inform your plugin user, that something went wrong and die.

We are will use this plugin from beginning to demonstrate error management. Suppose you have a task in gulpfile.js that contains this code (we modified it a little bit to be closer to real-usage):

var coffee = require('gulp-coffee');

Multiple Python installations on OS X

Previous versions used homebrew to install the various versions. As suggested in the comments, it's better to use pyenv instead. If you are looking for the previous version of this document, see the revision history.

$ brew update
$ brew install pyenv
$ pyenv install 3.5.0
$ pyenv install 3.4.3
$ pyenv install 3.3.6
$ pyenv install 3.2.6
$ pyenv install 2.7.10

$ pyenv install 2.6.9

Some useful Git aliases that I use every day
#
# Working with branches
#
# Get the current branch name (not so useful in itself, but used in
# other aliases)
branch-name = "!git rev-parse --abbrev-ref HEAD"
# Push the current branch to the remote "origin", and set it to track
# the upstream branch
publish = "!git push -u origin $(git branch-name)"
