 | 
			
		||||
## Python standards ##
 | 
			
		||||
Python code should conform to [PEP 8][].
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
## Cheatsheet Format ##
 | 
			
		||||
Please pattern your cheatsheets after the following:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
# To extract an uncompressed archive:
 | 
			
		||||
tar -xvf /path/to/foo.tar
 | 
			
		||||

# To extract a .gz archive:
 | 
			
		||||
tar -xzvf /path/to/foo.tgz
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
If you are submitting a cheatsheet that contains side-by-side columns of text,
 | 
			
		||||
please align the columns using spaces rather than tabs.

 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Installing
 | 
			
		||||
----------
 | 
			
		||||
It is recommended to install `cheat` with `pip`:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
pip install cheat --user
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
(You must ensure that the `Location` identified by `pip show cheat` exists on
 | 
			
		||||
your `PATH`.)
 | 
			
		||||
 | 
			
		||||
[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][].
 | 
			
		||||
`cheat` has no dependencies. To install it, download the executable from the
 | 
			
		||||
[releases][] page and place it on your `PATH`.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Configuring
 | 
			
		||||
-----------
 | 
			
		||||
 | 
			
		||||
### Setting a CHEAT_USER_DIR ###
 | 
			
		||||
Personal cheatsheets are saved in the `~/.cheat` directory by default, but you
 | 
			
		||||
can specify a different default by exporting a `CHEAT_USER_DIR` environment
 | 
			
		||||
variable:
 | 
			
		||||
### conf.yml ###
 | 
			
		||||
`cheat` is configured by a YAML file that can be generated with `cheat --init`:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
export CHEAT_USER_DIR='/path/to/my/cheats'
 | 
			
		||||
mkdir -p ~/.config/cheat && cheat --init > ~/.config/cheat/conf.yml
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
### Setting a CHEAT_PATH ###
 | 
			
		||||
You can additionally instruct `cheat` to look for cheatsheets in other
 | 
			
		||||
directories by exporting a `CHEAT_PATH` environment variable:
 | 
			
		||||
By default, the config file is assumed to exist on an XDG-compliant
 | 
			
		||||
configuration path like `~/.config/cheat/conf.yml`. If you would like to store
 | 
			
		||||
it elsewhere, you may export a `CHEAT_CONFIG_PATH` environment variable that
 | 
			
		||||
specifies its path:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
export CHEAT_PATH='/path/to/my/cheats'
 | 
			
		||||
export CHEAT_CONFIG_PATH="~/.dotfiles/cheat/conf.yml"
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
You may, of course, append multiple directories to your `CHEAT_PATH`:
 | 
			
		||||
Cheatsheets
 | 
			
		||||
-----------
 | 
			
		||||
Cheatsheets are plain-text files with no file extension, and are named
 | 
			
		||||
according to the command used to view them:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
export CHEAT_PATH="$CHEAT_PATH:/path/to/more/cheats"
 | 
			
		||||
cheat tar     # file is named "tar"
 | 
			
		||||
cheat foo/bar # file is named "bar", in a "foo" subdirectory
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
You may view which directories are on your `CHEAT_PATH` with `cheat -d`.
 | 
			
		||||
Cheatsheet text may optionally be preceeded by a YAML frontmatter header that
 | 
			
		||||
assigns tags and specifies syntax:
 | 
			
		||||
 | 
			
		||||
### Enabling Syntax Highlighting ###
 | 
			
		||||
`cheat` can optionally apply syntax highlighting to your cheatsheets. To
 | 
			
		||||
enable syntax highlighting, export a `CHEAT_COLORS` environment variable:
 | 
			
		||||
```
 | 
			
		||||
---
 | 
			
		||||
syntax: javascript
 | 
			
		||||
tags: [ array, map ]
 | 
			
		||||
---
 | 
			
		||||
// To map over an array:
 | 
			
		||||
const squares = [1, 2, 3, 4].map(x => x * x);
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The `cheat` executable includes no cheatsheets, but [community-sourced
 | 
			
		||||
cheatsheets are available][cheatsheets].
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Cheatpaths
 | 
			
		||||
----------
 | 
			
		||||
Cheatsheets are stored on "cheatpaths", which are directories that contain
 | 
			
		||||
cheetsheets. Cheatpaths are specified in the `conf.yml` file.
 | 
			
		||||
 | 
			
		||||
It can be useful to configure `cheat` against multiple cheatpaths. A common
 | 
			
		||||
pattern is to store cheatsheets from multiple repositories on individual
 | 
			
		||||
cheatpaths:
 | 
			
		||||
 | 
			
		||||
```yaml
 | 
			
		||||
# conf.yml:
 | 
			
		||||
# ...
 | 
			
		||||
cheatpaths:
 | 
			
		||||
  - name: community                   # a name for the cheatpath
 | 
			
		||||
    path: ~/documents/cheat/community # the path's location on the filesystem
 | 
			
		||||
    tags: [ community ]               # these tags will be applied to all sheets on the path
 | 
			
		||||
    readonly: true                    # if true, `cheat` will not create new cheatsheets here
 | 
			
		||||
 | 
			
		||||
  - name: personal
 | 
			
		||||
    path: ~/documents/cheat/personal  # this is a separate directory and repository than above
 | 
			
		||||
    tags: [ personal ]
 | 
			
		||||
    readonly: false                   # new sheets may be written here
 | 
			
		||||
# ...
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The `readonly` option instructs `cheat` not to edit (or create) any cheatsheets
 | 
			
		||||
on the path. This is useful to prevent merge-conflicts from arising on upstream
 | 
			
		||||
cheatsheet repositories.
 | 
			
		||||
 | 
			
		||||
If a user attempts to edit a cheatsheet on a read-only cheatpath, `cheat` will
 | 
			
		||||
transparently copy that sheet to a writeable directory before opening it for
 | 
			
		||||
editing.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Usage
 | 
			
		||||
-----
 | 
			
		||||
To view a cheatsheet:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
export CHEAT_COLORS=true
 | 
			
		||||
cheat tar      # a "top-level" cheatsheet
 | 
			
		||||
cheat foo/bar  # a "nested" cheatsheet
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Note that [pygments][] must be installed on your system for this to work.
 | 
			
		||||
 | 
			
		||||
`cheat` ships with both light and dark colorschemes to support terminals with
 | 
			
		||||
different background colors. A colorscheme may be selected via the
 | 
			
		||||
`CHEAT_COLORSCHEME` envvar:
 | 
			
		||||
To edit a cheatsheet:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
export CHEAT_COLORSCHEME=light # must be 'light' (default) or 'dark'
 | 
			
		||||
cheat -e tar     # opens the "tar" cheatsheet for editing, or creates it if it does not exist
 | 
			
		||||
cheat -e foo/bar # nested cheatsheets are accessed like this
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
#### 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].
 | 
			
		||||
To view the configured cheatpaths:
 | 
			
		||||
 | 
			
		||||
Example:
 | 
			
		||||
 | 
			
		||||
<pre>
 | 
			
		||||
```sql
 | 
			
		||||
-- to select a user by ID
 | 
			
		||||
SELECT *
 | 
			
		||||
FROM Users
 | 
			
		||||
WHERE id = 100
 | 
			
		||||
```sh
 | 
			
		||||
cheat -d
 | 
			
		||||
```
 | 
			
		||||
</pre>
 | 
			
		||||
 | 
			
		||||
If no syntax highlighter is specified, the `bash` highlighter will be used by
 | 
			
		||||
default.
 | 
			
		||||
To list all available cheatsheets:
 | 
			
		||||
 | 
			
		||||
### 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:
 | 
			
		||||
```sh
 | 
			
		||||
cheat -l
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
- blue
 | 
			
		||||
- cyan
 | 
			
		||||
- green
 | 
			
		||||
- grey
 | 
			
		||||
- magenta
 | 
			
		||||
- red
 | 
			
		||||
- white
 | 
			
		||||
- yellow
 | 
			
		||||
To list all cheatsheets that are tagged with "networking":
 | 
			
		||||
 | 
			
		||||
Note that the `termcolor` module must be installed on your system for this to
 | 
			
		||||
work.
 | 
			
		||||
```sh
 | 
			
		||||
cheat -l -t networking
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
To list all cheatsheets on the "personal" path:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
cheat -l -p personal
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
To search for the phrase "ssh" among cheatsheets:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
cheat -s ssh
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
To search (by regex) for cheatsheets that contain an IP address:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
cheat -r -s '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Flags may be combined in inuitive ways. Example: to search sheets on the
 | 
			
		||||
"personal" cheatpath that are tagged with "networking" and match a regex:
 | 
			
		||||
 | 
			
		||||
```sh
 | 
			
		||||
cheat -p personal -t networking -s --regex '(?:[0-9]{1,3}\.){3}[0-9]{1,3}'
 | 
			
		||||
```
 | 
			
		||||

            path. You might want to use this if you want multiple versions
 | 
			
		||||
            of your app to be able to run independently. If used, this
 |

            would typically be "<major>.<minor>".
 | 
			
		||||
            Only applied when appname is present.
 | 
			
		||||
        "opinion" (boolean) can be False to disable the appending of
 | 
			
		||||
            "Logs" to the base app data dir for Windows, and "log" to the
 | 
			
		||||
            base cache dir for Unix. See discussion below.
 | 
			
		||||
 | 
			
		||||
    Typical user log directories are:
 | 
			
		||||
        Mac OS X:   ~/Library/Logs/<AppName>
 | 
			
		||||
        Unix:       ~/.cache/<AppName>/log  # or under $XDG_CACHE_HOME if defined
 | 
			
		||||
        Win XP:     C:\Documents and Settings\<username>\Local Settings\Application Data\<AppAuthor>\<AppName>\Logs
 | 
			
		||||
        Vista:      C:\Users\<username>\AppData\Local\<AppAuthor>\<AppName>\Logs
 | 
			
		||||
 | 
			
		||||
    On Windows the only suggestion in the MSDN docs is that local settings
 | 
			
		||||
    go in the `CSIDL_LOCAL_APPDATA` directory. (Note: I'm interested in
 | 
			
		||||
    examples of what some windows apps use for a logs dir.)
 | 
			
		||||
 | 
			
		||||
    OPINION: This function appends "Logs" to the `CSIDL_LOCAL_APPDATA`
 | 
			
		||||
    value for Windows and appends "log" to the user cache dir for Unix.
 | 
			
		||||
    This can be disabled with the `opinion=False` option.

# Creating Subkeys
 | 
			
		||||
 | 
			
		||||
  Subkeys can be useful if you don't wish to have your main GPG key
 | 
			
		||||
  installed on multiple machines. In this way you can keep your
 | 
			
		||||
  master key safe and have subkeys with expiry periods or which may be
 | 
			
		||||
  separately revoked installed on various machines. This avoids
 | 
			
		||||
  generating entirely separate keys and so breaking any web of trust
 | 
			
		||||
  which has been established.
 | 
			
		||||
 | 
			
		||||
    gpg --edit-key <key ID>
 | 
			
		||||
 | 
			
		||||
  At the prompt type:
 | 
			
		||||
 | 
			
		||||
    addkey
 | 
			
		||||
 | 
			
		||||
  Choose RSA (sign only), 4096 bits and select an expiry period.
 | 
			
		||||
  Entropy will be gathered.
 | 
			
		||||
 | 
			
		||||
  At the prompt type:
 | 
			
		||||
 | 
			
		||||
    save
 | 
			
		||||
 | 
			
		||||
  You can also repeat the procedure, but selecting RSA (encrypt only).
 | 
			
		||||
  To remove the master key, leaving only the subkey/s in place:
 | 
			
		||||
 | 
			
		||||
    gpg --export-secret-subkeys <subkey ID> > subkeys
 | 
			
		||||
    gpg --export <key ID> > pubkeys
 | 
			
		||||
    gpg --delete-secret-key <key ID>
 | 
			
		||||
 | 
			
		||||
  Import the keys back.
 | 
			
		||||
 | 
			
		||||
    gpg --import pubkeys subkeys
 | 
			
		||||
 | 
			
		||||
  Verify the import.

		||||
 |
