|
|
* `IgnorePattern` class has the set of glob patterns and the base path.
|
|
*
|
|
* It provides two static methods.
|
|
*
|
|
* - `IgnorePattern.createDefaultIgnore(cwd)`
|
|
* Create the default predicate function.
|
|
* - `IgnorePattern.createIgnore(ignorePatterns)`
|
|
* Create the predicate function from multiple `IgnorePattern` objects.
|
|
*
|
|
* It provides two properties and a method.
|
|
*
|
|
* - `patterns`
|
|
* The glob patterns that ignore to lint.
|
|
* - `basePath`
|
|
* The base path of the glob patterns. If absolute paths existed in the
|
|
* glob patterns, those are handled as relative paths to the base path.
|
|
* - `getPatternsRelativeTo(basePath)`
|
|
* Get `patterns` as modified for a given base path. It modifies the
|
|
* absolute paths in the patterns as prepending the difference of two base
|
|
* paths.
|
|
*
|
|
* `ConfigArrayFactory` creates `IgnorePattern` objects when it processes
|
|
* `ignorePatterns` properties.

* @fileoverview The factory of `ConfigArray` objects.
|
|
*
|
|
* This class provides methods to create `ConfigArray` instance.
|
|
*
|
|
* - `create(configData, options)`
|
|
* Create a `ConfigArray` instance from a config data. This is to handle CLI
|
|
* options except `--config`.
|
|
* - `loadFile(filePath, options)`
|
|
* Create a `ConfigArray` instance from a config file. This is to handle
|
|
* `--config` option. If the file was not found, throws the following error:
|
|
* - If the filename was `*.js`, a `MODULE_NOT_FOUND` error.
|
|
* - If the filename was `package.json`, an IO error or an
|
|
* `ESLINT_CONFIG_FIELD_NOT_FOUND` error.
|
|
* - Otherwise, an IO error such as `ENOENT`.
|
|
* - `loadInDirectory(directoryPath, options)`
|
|
* Create a `ConfigArray` instance from a config file which is on a given
|
|
* directory. This tries to load `.eslintrc.*` or `package.json`. If not
|
|
* found, returns an empty `ConfigArray`.
|
|
* - `loadESLintIgnore(filePath)`
|
|
* Create a `ConfigArray` instance from a config file that is `.eslintignore`
|
|
* format. This is to handle `--ignore-path` option.
|
|
* - `loadDefaultESLintIgnore()`
|
|
* Create a `ConfigArray` instance from `.eslintignore` or `package.json` in
|
|
* the current working directory.
|
|
*
|
|
* `ConfigArrayFactory` class has the responsibility that loads configuration
|
|
* files, including loading `extends`, `parser`, and `plugins`. The created
|
|
* `ConfigArray` instance has the loaded `extends`, `parser`, and `plugins`.
|
|
*
|
|
* But this class doesn't handle cascading. `CascadingConfigArrayFactory` class
|
|
* handles cascading and hierarchy.

|
|
* Clear the internal cache. You have to call this method when

|
* `additionalPluginPool` was updated if `baseConfig` or `cliConfig` depends
|
|
* on the additional plugins. (`CLIEngine#addPlugin()` method calls this.)
