;;; Commentary:

;; All the variables related to Java management in just one place.

;;; Code:

;; Group definition:

(defgroup languagetool-java nil
  "LanguageTool Java related configuration."
  :tag "Java"
  :prefix "languagetool-java-"
  :group 'languagetool)

;; Variable definitions:

(defcustom languagetool-java-bin (executable-find "java")
  "Java executable path."
  :group 'languagetool-java
  :type 'file)

(defcustom languagetool-java-arguments nil
  "Java extra arguments.

Described at http://wiki.languagetool.org/command-line-options,
recommends to use:

\(setq `languagetool-java-arguments' '(\"-Dfile.encoding=UTF-8\"))

When using LanguageTool via it classes this variable should be
set to:

\(setq `languagetool-java-arguments'
      '(\"-Dfile.encoding=UTF-8\"
        \"-cp\"
        \"/path/to/classes:/path/to/classes\"))

For example to use in Arch Linux (with pacman dependency):

\(setq `languagetool-java-arguments'
      '(\"-Dfile.encoding=UTF-8\"
        \"-cp\"
        \"/usr/share/languagetool:/usr/share/java/languagetool/*\"))"
  :group 'languagetool-java
  :type '(choice
          (const nil)
          (repeat string)))

;; Function definitions:

(defun languagetool-java-parse-arguments ()
  "Return Java parsed arguments as a list."
  (unless (listp languagetool-java-arguments)
    (error "LanguageTool Java Arguments must be a list of strings"))

  (let (arguments)

    (push languagetool-java-arguments arguments)

    (flatten-tree (reverse arguments))))

(provide 'languagetool-java)
