Configuration

phpstan.configFile - path to the config file, either relative to phpstan.rootDir or absolute. Use a comma-separated list to resolve in the listed order. For example if phpstan.neon,phpstan.neon.dist is used, the extension will first try to use phpstan.neon if it exists and fall back to phpstan.neon.dist.
phpstan.rootDir - path to the root directory of your PHP project (defaults to workspaceFolder)
phpstan.binPath - path to the PHPStan binary (defaults to ${workspaceFolder}/vendor/bin/phpstan)
phpstan.binCommand - command that runs the PHPStan binary. Use this if, for example, PHPStan is already in your global path. If this is specified, it is used instead of phpstan.binPath. Unset by default.

phpstan.options - array of command line options to pass to PHPStan (defaults to [])
phpstan.memoryLimit - memory limit to use when running PHPStan (defaults to 1G)
phpstan.timeout - timeout for checking single files after which the PHPStan process is killed in ms (defaults to 10000ms)
phpstan.projectTimeout - timeout for checking the entire project after which the PHPStan process is killed in ms (defaults to 60000ms)
phpstan.suppressTimeoutMessage - whether to disable the error message when the check times out (defaults to false)
phpstan.paths - path mapping that allows for rewriting paths. Can be useful when developing inside a docker container or over SSH. Unset by default. Example for making the extension work in a docker container: { "/path/to/hostFolder": "/path/in/dockerContainer" }
phpstan.ignoreErrors - An array of regular expressions to ignore in error messages. If you find the PHPStan process erroring often because of a warning that can be ignored, put the warning in here and it'll be ignored in the future.

phpstan.enabled - whether to enable the on-save checker (defaults to true)
phpstan.enableStatusBar - whether to show a statusbar entry while performing the check (defaults to true)
phpstan.enableLanguageServer - Whether to enable the language server that provides on-hover information. Disable this if you're using a custom PHPStan binary that runs on another filesystem (such as Docker) and you're running into issues (defaults to true)
phpstan.showProgress - whether to show the progress bar when performing a single-file check (defaults to false)

First get your dev environment started by running yarn dev. Note that this expects you to have a few programs installed:

This command installs all JS and PHP dependencies and ensures you're ready to go for writing a PHPStan extension.

The following command will run PHPStan on a demo file, this is handy for testing out changes to the PHPStan plugin that collects hover data.

php/vendor/bin/phpstan analyze -c php/config.neon -a php/TreeFetcher.php --debug test/demo/php/DemoClass.php
