Using Docker (phpstan/docker-image)

Install Docker and phpstan/phpstan image.

If you always use Docker for PHPStan, add the following into your .emacs file (~~/.emacs.d/init.el~)

(setq-default phpstan-executable 'docker)

Put the following into .dir-locals.el files on the root directory of project.

((nil . ((php-project-root . git)
         (phpstan-executable . docker)
         (phpstan-working-dir . (root . "path/to/dir"))
         (phpstan-config-file . (root . "path/to/dir/phpstan-docker.neon"))
	 (phpstan-memory-limit . "1G")
         (phpstan-level . 7))))

Using composer (project specific)

If your project Composer relies on phpstan, you do not need to set anything.

((nil . ((php-project-root . git)
         (phpstan-executable . docker)
         (phpstan-working-dir . (root . "path/to/dir"))
         (phpstan-config-file . (root . "path/to/dir/phpstan-docker.neon"))
         (phpstan-level . 7))))

Using Composer

Please install phpstan/phpstan package for each user environment or project by using Composer.

If you are unfamiliar with resolving dependencies, the following shell commands are recommended.

$ composer global require phpstan/phpstan

NOTICE: phpstan/phpstan-shim is deprecated. Please read PHPStan 0.12 Released!.

Using PHAR archive

NOTICE: phpstan.el requires PHPStan **0.10+**. We strongly recommend using the latest PHPStan.

Please download phpstan.phar from Releases · phpstan/phpstan.

Settings

Variables for phpstan are mainly controlled by directory variables (.dir-locals.el).

Frequently (root. "path/to/file") notation appears in these variables. It is relative to the top level directory of the project. In general, the directory containing one of .projectile, composer.json, .git file (or directory) is at the top level.

Please be aware that the root directory of the PHP project may NOT match either of PHPStan’s %rootDir% and/or %currentWorkingDirectory%.

Typically, you would set the following .dir-locals.el.

((nil . ((php-project-root . auto)
         (phpstan-executable . docker)
         (phpstan-working-dir . (root . "path/to/dir/"))
         (phpstan-config-file . (root . "path/to/dir/phpstan-custom.neon"))
         (phpstan-level . max))))

If there is a phpstan.neon file in the root directory of the project, you do not need to set both phpstan-working-dir and phpstan-config-file.

Commands

This package provides convenient commands for using PHPStan from Emacs.

Command phpstan-insert-dumptype

Add PHPStandumpType(...); to your PHP code and analyze it to make PHPStan display the type of the expression.

(define-key php-mode-map (kbd "C-c ^") #'phpstan-insert-dumptype)

By default, if you press C-u before invoking the command, PHPStandumpPhpDocType() will be inserted.

This feature was added in PHPStan 1.12.7 and will dump types compatible with the @param and @return PHPDoc tags.

Command phpstan-insert-ignore

Insert a @phpstan-ignore tag to suppress any PHPStan errors on the current line.

By default it inserts the tag on the previous line, but if there is already a tag at the end of the current line or on the previous line, the identifiers will be appended there.

If there is no existing tag and C-u is pressed before the command, it will be inserted at the end of the line.
