ruby gists_to_dash_db.rb

Posted 2021-05-16

How to
======

Create or edit a gist
---------------------

In your gist description, add a keyword like : #jquery


Launch the script
-----------------

Launch the script without arguments to see the usage.
The script will use the keyword to fill the abbreviation field in Dash and fill the snippet with the gist content

Example
-------

You could run :

    chmod +x gists_to_dash.rb
    ./gists_to_dash.rb voising Dropbox/Configs/snippets.dash "$" no_comments

More about the char_appended_to_keyword argument
--------------------------------------------

When you write your snippets you may use a key at the end of the abbreviation. That's what this argument stands for.

If the keyword is #calljquery and the char_appended_to_keyword is "$", the snippet abbreviation will be : calljquery$
