Usage:
psalm [options] [file...]
Options:
-h, --help
Display this help message
--debug
Debug information
-c, --config=psalm.xml
Path to a psalm.xml configuration file. Run psalm --init to create one.
-m, --monochrome
Enable monochrome output
-r, --root
If running Psalm globally you'll need to specify a project root. Defaults to cwd
--plugin=PATH
Executes a plugin, an alternative to using the Psalm config
--dry-run
Shows a diff of all the changes, without making them
2018-01-07 23:17:18 +01:00
--safe-types
Only update PHP types when the new type information comes from other PHP types,
as opposed to type information that just comes from docblocks
--php-version=PHP_MAJOR_VERSION.PHP_MINOR_VERSION
--issues=IssueType1,IssueType2
If any issues can be fixed automatically, Psalm will update the codebase
