## Alignment

Example of automatic alignment.

```python
class TokenType(enum.Enum):           # class TokenType(enum.Enum):

    INDENT    = 0                     #     INDENT = 0
    SEPARATOR = 1                     #     SEPARATOR = 1
    CODE      = 2                     #     CODE = 2


Indent      = str                     # Indent = str
RowIndex    = int                     # RowIndex = int
ColIndex    = int                     # ColIndex = int
OffsetWidth = int                     # OffsetWidth = int
TokenTable  = typ.List[TokenRow]      # TokenTable = typ.List[TokenRow]
```

## Usage

Usage is exactly the same as for `black`, except that the command is named `sjfmt`.

```shell
$ pip install straitjacket
$ sjfmt --help
Usage: sjfmt [OPTIONS] [SRC]...

  Another uncompromising code formatter.

Options:
  -l, --line-length INTEGER       How many characters per line to allow.
                                  [default: 88]
  --py36                          Allow using Python 3.6-only syntax on all
```

## Editor/Tooling Integration

Plugins for your editor usually support setting a custom path to black. You
can simply point to sjfmt instead.

Unix
```shell
$ which sjfmt
/home/user/miniconda3/envs/py36/bin/sjfmt
$ which sjfmtd
/home/user/miniconda3/envs/py36/bin/sjfmtd
```

Windows
```shell
C:\Users\Username>where sjfmt
C:\Python37\Scripts\sjfmt.exe

or

PS C:\Users\Username> (gcm sjfmt).Path
C:\Python37\Scripts\sjfmt.exe
```

### [sublack](https://github.com/jgirardet/sublack):

```json
{

    "black_command": "C:/Python37/Scripts/sjfmt.exe",
    "black_line_length": 100,
    // ...
}
```

Document formatting can be triggered with `Ctrl+Alt+F`.


### [vscode python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python)


```json
{
    "python.formatting.provider": "black",
    "python.formatting.blackPath": "C:\\Python37\\Scripts\\sjfmt.exe",
    "python.formatting.blackArgs": [
        "--line-length", "100",
        "--py36",
        "--skip-string-normalization"
    ],
}
```

Document formatting can be triggered with `Shift+Alt+F`.


### [BlackPycharm](https://github.com/pablogsal/black-pycharm)

Install the plugin `black-pycharm`, which can be found in
`Settings > Plugins > Brows Repositories`. You may have to
restart PyCharm for the plugin to load.

To configure the path, go to `Settings > Tools > BlackPycharm
Configuration` and set `Path to Black executable` to the location
of the sjfmt binary.

You can reformat your code using `Ctrl + Shift + A` to access the
`Find Action` panel. The name of the action to format your code
is `Reformat code (BLACK)`. You may want to rebind this action,
at least in my setup the default binding didn't seem to work.


## Flake8

By the nature of this plugin, certain flake8 codes will be
violated. This is an excerpt from what you might put in your
`setup.cfg` to ignore these:

```
[flake8]
ignore =
    # No whitespace after paren open "("
    E201
    # No whitespace before paren ")"
    E202
    # Whitespace before ":"
    E203
    # Multiple spaces before operator
    E221
    # Multiple spaces after operand
    E222
    # Multiple spaces after ':'
    E241
    # Multiple spaces before keyword
    E272
    # Spaces around keyword/parameter equals
    E251
```
