Tasks

Human Readable Information

Runtime State

Executing the Linter

  • public function willLintPaths($paths)
  • final public function lintPath($path)
  • public function didLintPaths($paths)
  • final protected function getExecutableCommand() — Get the composed executable command, including the interpreter and binary but without flags or paths. This can be used to execute `--version` commands.
  • final protected function getCommandFlags() — Get the composed flags for the executable, including both mandatory and configured flags.

Interpreters, Binaries and Flags

  • public function getDefaultBinary()
  • public function getInstallInstructions()
  • public function getUpgradeInstructions() — Return a human-readable string describing how to upgrade the linter.
  • public function shouldExpectCommandErrors(...) — Return true to continue when the external linter exits with an error code. By default, linters which exit with an error code are assumed to have failed. However, some linters exit with a specific code to indicate that lint messages were detected.
  • protected function getMandatoryFlags()
  • protected function getDefaultFlags() — Provide default, overridable flags to the linter. Generally these are configuration flags which affect behavior but aren't critical. Flags which are required should be provided in @{method:getMandatoryFlags} instead.
  • final public function setFlags($flags) — Override default flags with custom flags. If not overridden, flags provided by @{method:getDefaultFlags} are used.
  • final public function setVersionRequirement($version) — Set the binary's version requirement.
  • final public function getBinary() — Return the binary or script to execute. This method synthesizes defaults and configuration. You can override the binary with @{method:setBinary}.
  • final public function setBinary($bin) — Override the default binary with a new one.
  • public function shouldUseInterpreter() — Return true if this linter should use an interpreter (like "python" or "node") in addition to the script.
  • public function getDefaultInterpreter() — Return the default interpreter, like "python" or "node". This method is only invoked if @{method:shouldUseInterpreter} has been overridden to return `true`.
  • final public function getInterpreter() — Get the effective interpreter. This method synthesizes configuration and defaults.
  • final public function setInterpreter($interpreter) — Set the interpreter, overriding any default.

Return a human-readable string describing how to upgrade the linter.

Return
stringHuman readable upgrade instructions

public function shouldExpectCommandErrors(...)
Inherited

ArcanistExternalLinter

Return true to continue when the external linter exits with an error code. By default, linters which exit with an error code are assumed to have failed. However, some linters exit with a specific code to indicate that lint messages were detected.

If the linter sometimes raises errors during normal operation, override this method and return true so execution continues when it exits with a nonzero status.

Parameters
boolReturn true to continue on nonzero error code.
Return
wild

protected function getMandatoryFlags()

ArcanistExternalLinter

Provide mandatory, non-overridable flags to the linter. Generally these are format flags, like --format=xml, which must always be given for the output to be usable.

Flags which are not mandatory should be provided in getDefaultFlags() instead.

ArcanistRuboCopLinter
This method is not documented.
Return
list<string>Mandatory flags, like `"--format=xml"`.

protected function getDefaultFlags()

ArcanistExternalLinter

Provide default, overridable flags to the linter. Generally these are configuration flags which affect behavior but aren't critical. Flags which are required should be provided in getMandatoryFlags() instead.

Default flags can be overridden with setFlags().

Return
list<string>Overridable default flags.

final public function setFlags($flags)
Inherited

ArcanistExternalLinter

Override default flags with custom flags. If not overridden, flags provided by getDefaultFlags() are used.

Parameters

ArcanistExternalLinter

Set the binary's version requirement.

Parameters
string$versionVersion requirement.
Return

After overriding this method to return true, override getDefaultInterpreter() to set a default.

Return
boolTrue to use an interpreter.

public function getDefaultInterpreter()

Return
stringEffective interpreter.

Return
this

protected function parseLinterOutput($path, $err, $stdout, $stderr)

ArcanistExternalLinter

Parse the output of the external lint program into objects of class ArcanistLintMessage which arc can consume. Generally, this means examining the output and converting each warning or error into a message.

If parsing fails, returning false will cause the caller to throw an appropriate exception. (You can also throw a more specific exception if you're able to detect a more specific condition.) Otherwise, return a list of messages.

ArcanistRuboCopLinter
This method is not documented.
Parameters
string$pathPath to the file being linted.
int$errExit code of the linter.
string$stdoutStdout of the linter.
