|

`fish_indent` is used to indent a piece of fish code. `fish_indent` reads commands from standard input and outputs them to standard output.
|
||||
`fish_indent` is used to indent a piece of fish code. `fish_indent` reads commands from standard input and outputs them to standard output or a specified file.
|
||||
|
||||
The following options are available:
|
||||
|
||||
- `-d` or `--dump` dumps information about the parsed fish commands to stderr
|
||||
|
||||
- `-w` or `--write` indents a specified file and immediately writes to that file
|
||||
|
||||
- `-i` or `--no-indent` do not indent commands; only reformat to one job per line
|
||||
|
||||
- `-v` or `--version` displays the current fish version and then exits
