=====
|
|
`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.
|
|
|
|
|
|
|
|
|
|
Example
|
|
-------
|
|
The next time you're forced to disarm a nuclear weapon without consulting
|
|
Google, you may run:
|
|
|
|
```sh
|
|
cheat tar
|
|
```
|
|
|
|
You will be presented with a cheatsheet resembling:
|
|
|
|
```sh
|
|
# To extract an uncompressed archive:
|
|
tar -xvf '/path/to/foo.tar'
|
|
|
|
# To extract a .gz archive:
|
|
tar -xzvf '/path/to/foo.tgz'
|
|
|
|
# To create a .gz archive:
|
|
tar -czvf '/path/to/foo.tgz' '/path/to/foo/'
|
|
|
|
# To extract a .bz2 archive:
|
|
tar -xjvf '/path/to/foo.tgz'
|
|
|
|
# To create a .bz2 archive:
|
|
tar -cjvf '/path/to/foo.tgz' '/path/to/foo/'
|
|
```
|
|
|
|
To see what cheatsheets are available, run `cheat -l`.
|
|
|
|
Note that, while `cheat` was designed primarily for \*nix system administrators,
|
|
it is agnostic as to what content it stores. If you would like to use `cheat`
|
|
to store notes on your favorite cookie recipes, feel free.
|
|
|
|
|
|
Installing
|
|
----------
|
|
It is recommended to install `cheat` with `pip`:
|
|
|
|
```sh
|
|
[sudo] pip install cheat
|
|
```
|
|
|
|
[Other installation methods are available][installing].
|
|
|
|
|
|
Modifying Cheatsheets
|
|
---------------------
|
|
The value of `cheat` is that it allows you to create your own cheatsheets - the
|
|
defaults are meant to serve only as a starting point, and can and should be
|
|
modified.
|
|
|
|
Cheatsheets are stored in the `~/.cheat/` directory, and are named on a
|
|
per-keyphrase basis. In other words, the content for the `tar` cheatsheet lives
|
|
in the `~/.cheat/tar` file.
|
|
|
|
Provided that you have a `CHEAT_EDITOR`, `VISUAL`, or `EDITOR` environment
|
|
variable set, you may edit cheatsheets with:
|
|
|
|
```sh
|
|
cheat -e foo
|
|
```
|
|
|
|
If the `foo` cheatsheet already exists, it will be opened for editing.
|
|
Otherwise, it will be created automatically.
|
|
|
|
After you've customized your cheatsheets, I urge you to track `~/.cheat/` along
|
|
with your [dotfiles][].
|
|
|
|
|
|
Configuring
|
|
-----------
|
|
|
|
### Setting a DEFAULT_CHEAT_DIR ###
|
|
Personal cheatsheets are saved in the `~/.cheat` directory by default, but you
|
|
can specify a different default by exporting a `DEFAULT_CHEAT_DIR` environment
|
|
variable:
|
|
|
|
```sh
|
|
export DEFAULT_CHEAT_DIR='/path/to/my/cheats'
|
|
```
|
|
|
|
### Setting a CHEATPATH ###
|
|
You can additionally instruct `cheat` to look for cheatsheets in other
|
|
directories by exporting a `CHEATPATH` environment variable:
|
|
|
|
```sh
|
|
export CHEATPATH='/path/to/my/cheats'
|
|
```
|
|
|
|
You may, of course, append multiple directories to your `CHEATPATH`:
|
|
|
|
```sh
|
|
export CHEATPATH="$CHEATPATH:/path/to/more/cheats"
|
|
```
|
|
|
|
You may view which directories are on your `CHEATPATH` with `cheat -d`.
|
|
|
|
### Enabling Syntax Highlighting ###
|
|
`cheat` can optionally apply syntax highlighting to your cheatsheets. To
|
|
enable syntax highlighting, export a `CHEATCOLORS` environment variable:
|
|
|
|
```sh
|
|
export CHEATCOLORS=true
|
|
```
|
|
|
|
Note that [pygments][] must be installed on your system for this to work.
|
|
|
|
|
|
#### Specifying a Syntax Highlighter ####
|
|
You may manually specify which syntax highlighter to use for each cheatsheet by
|
|
wrapping the sheet's contents in a [Github-Flavored Markdown code-fence][gfm].
|
|
|
|
Example:
|
|
|
|
<pre>
|
|
```sql
|
|
-- to select a user by ID
|
|
SELECT *
|
|
FROM Users
|
|
WHERE id = 100
|
|
```
|
|
</pre>
|
|
|
|
If no syntax highlighter is specified, the `bash` highlighter will be used by
|
|
default.
|
|
|
|
### Enabling Search Match Highlighting ###
|
|
`cheat` can optionally be configured to highlight search term matches in search
|
|
results. To do so, export a `CHEAT_HIGHLIGHT` environment variable with a value
|
|
of one of the following:
|
|
|
|
- blue
|
|
- cyan
|
|
- green
|
|
- grey
|
|
- magenta
|
|
- red
|
|
- white
|
|
- yellow
|
|
|
|
Note that the `termcolor` module must be installed on your system for this to
|
|
work.
