int|null$byte_limitMaximum number of bytes permitted in the value.
Return
stringValue of the constant.

public function getInfoURI()
Inherited

ArcanistLinter

Return an optional informative URI where humans can learn more about this linter.

For most linters, this should return a link to the project home page. This is shown on arc linters.

Return
string|nullOptionally, return an informative URI.

public function getInfoDescription()

ArcanistLinter

Return a brief human-readable description of the linter.

These should be a line or two, and are shown on arc linters.

ArcanistLinter

Return arbitrary additional information.

Linters can use this method to provide arbitrary additional information to be included in the output of arc linters.

This method is not documented.
Return
map<string, string>A mapping of header to body content for the additional information sections.

public function willLintPaths($paths)
Inherited

ArcanistLinter

Hook called before a list of paths are linted.

Parallelizable linters can start multiple requests in parallel here, to improve performance. They can implement didLintPaths() to collect results.

Linters which are not parallelizable should normally ignore this callback and implement lintPath() instead.

Parameters
list<string>$pathsA list of paths to be linted
Return
void

final public function lintPath($path)
Inherited

ArcanistLinter

Hook called for each path to be linted.

Linters which are not parallelizable can do work here.

Linters which are parallelizable may want to ignore this callback and implement willLintPaths() and didLintPaths() instead.

Parameters
string$pathPath to lint.
Return
void

public function didLintPaths($paths)
Inherited

ArcanistLinter

Hook called after a list of paths are linted.

Parallelizable linters can collect results here.

final protected function getXHPASTLinter()
Inherited

ArcanistBaseXHPASTLinter

Get the linter object which is responsible for building parse trees.

When the engine specifies that several XHPAST linters should execute, we designate one of them as the one which will actually build parse trees. The other linters share trees, so they don't have to recompute them.

Roughly, the first linter to execute elects itself as the builder. Subsequent linters request builds and retrieve results from it.

Return
ArcanistBaseXHPASTLinterResponsible linter.

ArcanistBaseXHPASTLinter

Release futures on this linter which are no longer in use elsewhere.

Parameters
list<string>$pathsPaths to release futures for.
Return
void

final protected function getXHPASTTreeForPath($path)
Inherited

ArcanistBaseXHPASTLinter

Get a path's tree from the responsible linter.

Parameters
string$pathPath to retrieve tree for.
Return
XHPASTTree|nullTree, or null if unparseable.

final protected function getXHPASTExceptionForPath($path)
Inherited

ArcanistBaseXHPASTLinter

Return
this
