Are you a hack programmer? Do you find yourself constantly Googling for
how to do basic programing tasks?
Suppose you want to know how to format a date in bash. Why open your browser
and read through blogs (risking major distraction) when you can simply stay
in the console and ask howdoi:
::
$ howdoi format date bash
> DATE=`date +%Y-%m-%d`
howdoi will answer all sorts of queries:
::
$ howdoi print stack trace python
> import traceback
>
> try:
> 1/0
> except:
> print '>>> traceback <<<'
> traceback.print_exc()
> print '>>> end of traceback <<<'
> traceback.print_exc()
$ howdoi convert mp4 to animated gif
> video=/path/to/video.avi
> outdir=/path/to/output.gif
> mplayer "$video" \
> -ao null \
> -ss "00:01:00" \ # starting point
> -endpos 10 \ # duration in second
> -vo gif89a:fps=13:output=$outdir \
> -vf scale=240:180
$ howdoi create tar archive
> tar -cf backup.tar --exclude "www/subf3" www

Notes
-----
- Works with Python2 and Python3
- A standalone Windows executable with the howdoi application `is available here <https://dl.dropbox.com/u/101688/website/misc/howdoi.exe>`_.
- An Alfred Workflow for howdoi can be found at `http://blog.gleitzman.com/post/48539944559/howdoi-alfred-even-more-instant-answers <http://blog.gleitzman.com/post/48539944559/howdoi-alfred-even-more-instant-answers>`_.
- Slack integration available through `slack-howdoi <https://github.com/ellisonleao/slack-howdoi>`_.
- Howdoi uses a cache for faster access to previous questions. Caching functionality can be disabled by setting the HOWDOI_DISABLE_CACHE environment variable. The cache is stored in `~/.cache/howdoi`.
- You can set the HOWDOI_URL environment variable to change the source url for answers (default: stackoverflow.com). Other options include `serverfault.com` or `pt.stackoverflow.com`. Here's the `full list <http://stackexchange.com/sites?view=list#traffic>`_.
- Setting the HOWDOI_COLORIZE environment variable will colorize the output by default.
- Special thanks to Rich Jones (`@miserlou <https://github.com/miserlou>`_) for the idea.
Development
-----------
- Checkout the repo
- Run `python -m howdoi.howdoi QUERY` (if you try running `python howdoi/howdoi.py` you my get `ValueError: Attempted relative import in non-package`).
Troubleshooting
---------------
You might get the following error when installing with Homebrew:
::
==> python setup.py install

Please make the appropriate changes for your system and try again.
Fix the error by executing the following command:
::
sudo chmod -R go+w /Library/Python/2.7/site-packages/
An official lxml for python 3.3+ for windows has not yet been released. You may get an error while installing.
Try and install an unofficial binary for lxml from
