Previously, `sheets.print()` would query the filesystem every time it was invoked. This was inelegant, because it is called multiple times every time `cheat` is executed. Thus, unnecessary calls were being made out to the filesystem. Now the result of that function is being buffered into a module variable when it is executed the first time, and served from there thereafter. I broke the "functional" paradigm to a degree by doing this, but it wasn't worth the complexity of implementing proper memoization (decorators, etc) for such a trivial case. Bumped the version number accordingly.

Usage:
|
|
cheat <cheatsheet>
|
|
cheat -e <cheatsheet>
|
|
cheat -s <keyword>
|
|
cheat -l
|
|
cheat -d
|
|
cheat -v
|
|
|
|
cheat allows you to create and view interactive cheatsheets on the
|
|
command-line. It was designed to help remind *nix system
|
|
administrators of options for commands that they use frequently,
|
|
but not frequently enough to remember.
|
|
|
|
Examples:
|
|
To look up 'tar':
|
|
cheat tar
|
|
|
|
To create or edit the cheatsheet for 'foo':
|
|
cheat -e foo
|
|
|
|
Options:
|
|
-d --directories List directories on CHEATPATH
|
|
-e --edit Edit cheatsheet
|
|
-l --list List cheatsheets
|
|
-s --search Search cheatsheets for <keyword>
|
|
-v --version Print the version number
