atom-linter is an npm helper module that you can import in your Linter Providers and make things easier for yourself.
API
For full documentation of exec and execNode API, please refer to sb-exec README
export const FindCache: Map
export function exec(command: String, args: Array<string> = [], options: Object): Promise
export function execNode(filePath: String, args: Array<string> = [], options: Object): Promise
export function parse(data: String, regex: String, options: Object = {flags: 'g'}): Array<Linter$Message>
export function generateRange(textEditor: TextEditor, lineNumber: Number = 0, colStart: Number = <firstTextColumn>): Array
export function find(directory: String, names: String | Array<string>): ?String
export function findCached(directory: String, names: String | Array<string>): ?String
export function findAsync(directory: String, names: String | Array<string>): Promise<?String>
export function findCachedAsync(directory: String, names: String | Array<string>): Promise<?String>
export function tempFile<T>(fileName: String, fileContents: String, callback: Function<T>): Promise<T>
export function tempFiles<T>(filesNames: Array<{ name: String, contents: String }>, callback: Function<T>): Promise<T>Unique Spawning
To make sure that old processes spawned by your linter provider are terminated on a newer invocation, you can specify uniqueKey: "my-linter" in exec or execNode options. Please note that killed processes will return null as return value, so make sure to handle that.
Example:
import atomLinter from 'atom-linter'
const myLinter = {
// ...
async lint(textEditor) {
const output = atomLinter.exec('myprogram', ['parameter1', 'parameter2'], { uniqueKey: 'my-linter' })
// NOTE: Providers should also return null if they get null from exec
// Returning null from provider will tell base linter to keep existing messages
if (output === null) {
return null
}
// ... parse output and return messages
return []
}
