# `fmt` Command
|
|
|
|
The `packer fmt` Packer command is used to format HCL2 configuration files to
|
|
a canonical format and style. JSON files (.json) are not modified. This command
|
|
applies a subset of HCL language style conventions, along with other minor
|
|
adjustments for readability.
|
|
|
|
`packer fmt` will display the name of the configuration file(s) that need formatting,
|
|
and write any formatted changes back to the original configuration file(s).
|
|
|
|
Example usage:
|
|
|
|
Check if configuration file(s) need to be formatted, but don't write the changes.
|
|
|
|
```shell-session
|
|
$ packer fmt -check .
|
|
my-template.json
|
|
|
|
```
|
|
|
|
Format a configuration file, writing the changes back to the original file.
|
|
|
|
```shell-session
|
|
$ packer fmt my-template.json
|
|
my-template.json
|
|
|
|
```
|
|
|
|
## Options
|
|
|
|
- `-check` - Checks if the input is formatted. Exit status will be 0 if all
|
|
input is properly formatted and non-zero otherwise.
|
|
|
|
- `-diff` - Display diffs of any formatting change
|
|
|
|
- `-write=false` - Don't write formatting changes to source files
|
|
(always disabled if using -check)
