The fmt command
The fmt
command formats a given Alloy configuration file.
Usage
Usage:
alloy fmt [<FLAG> ...] <FILE_NAME>
Replace the following:
<FLAG>
: One or more flags that define the input and output of the command.<FILE_NAME>
: The Alloy configuration file.
If the <FILE_NAME>
argument isn’t provided or if the <FILE_NAME>
argument is equal to -
, fmt
formats the contents of standard input.
Otherwise, fmt
reads and formats the file from disk specified by the argument.
The --write
flag can be specified to replace the contents of the original file on disk with the formatted results.
--write
can only be provided when fmt
isn’t reading from standard input.
The command fails if the file being formatted has syntactically incorrect Alloy configuration, but doesn’t validate whether Alloy components are configured properly.
The following flags are supported:
--write
,-w
: Write the formatted file back to disk when not reading from standard input.
