Martino Pilia 771581a945 Add settings for the Alex linter ... The executable for the Alex linter is currently hard-coded as 'alex', which is an issue given the fact that it conflicts with the Haskell lexer generator, whose executable is also called 'alex', has been around a dozen years before the linter, and is packaged in the official repositories of the major Linux distributions. This commit adds options to use a local executable for the alex linter (which is a node package), and an option to set a custom executable. As side changes: * The pattern in the alex handler is made more readable by turnig it into a very-magic regex. * Alex handles plain text, markdown, and HTML. Specific flags for HTML and markdown are provided when instantiating the linters for the respective filetypes, while before those formats were treated as plain text.		2019-02-02 16:20:14 +01:00
