Flymake support for LanguageTool.

💾 Installation

The instruction to use this plugin.

For a Local Server: Download LanguageTool from https://languagetool.org/download/ and extract on to your local machine. For a Remote Server: If you are using LanguageTool's API and have a premium account you will need your username and an api key you can generate here https://languagetool.org/editor/settings/access-tokens
Consider adding one of the following snippets to your configuration.

Local LanguageTool Server

(use-package flymake-languagetool
  :ensure t
  :hook ((text-mode       . flymake-languagetool-load)
         (latex-mode      . flymake-languagetool-load)
         (org-mode        . flymake-languagetool-load)
         (markdown-mode   . flymake-languagetool-load))
  :init
  ;; Local Server Configuration
  (setq flymake-languagetool-server-jar
	"path/to/LanguageTool-X.X/languagetool-server.jar"))

Free LanguageTool Account

(use-package flymake-languagetool
  :ensure t
  :hook ((text-mode       . flymake-languagetool-load)
         (latex-mode      . flymake-languagetool-load)
         (org-mode        . flymake-languagetool-load)
         (markdown-mode   . flymake-languagetool-load))
  :init
  ;; LanguageTools API Remote Server Configuration
  (setq flymake-languagetool-server-jar nil)
  (setq flymake-languagetool-url "https://api.languagetool.org"))

Premium LanguageTool Account

(use-package flymake-languagetool
  :ensure t
  :hook ((text-mode       . flymake-languagetool-load)
         (latex-mode      . flymake-languagetool-load)
         (org-mode        . flymake-languagetool-load)
         (markdown-mode   . flymake-languagetool-load))
  :init
  ;; If using Premium Version provide the following information
  (setq flymake-languagetool-server-jar nil)
  (setq flymake-languagetool-url "https://api.languagetoolplus.com")
  (setq flymake-languagetool-api-username "myusername")
  (setq flymake-languagetool-api-key "APIKEY"))

🎉 Done! Now open a text file and hit M-x flymake-mode!

Another option is to add flymake-languagetool-maybe-load to find-file-hook, this way flymake-languagetool will be enabled whenever flymake-mode is active and the current major-mode is included in flymake-languagetool-active-modes.

(add-hook 'find-file-hook 'flymake-languagetool-maybe-load)

🧪 Configuration

Language

The language used for flymake can be customized by using flymake-languagetool-language (Default "en-US")

Active Modes

If you are using flymake-languagetool-maybe-load you can customize which modes flymake-languagetool will be enabled for by adding a major-mode to flymake-languagetool-active-modes. The default value is '(text-mode latex-mode org-mode markdown-mode message-mode)

Spellchecking

LanguageTool’s spellchecking is disabled by default. If flymake-languagetool-check-spelling is non-nil LanguageTool will check for spelling mistakes.

Disabling Rules & Categories

Specific rules can be disabled using flymake-languagetool-disabled-rules. For example, LanguageTool's whitespace rule can be a bit verbose in org-mode and it can be disabled by adding its ID to this variable.

(push "WHITESPACE_RULE" flymake-languagetool--disabled-rules)

The full list of rules and their IDs can be found here.

Similarly, you can disable categories using the flymake-languagetool-disabled-categories variable. The full list of categories can be found in flymake-languagetool-map

You can also disable rules and categories interactively with the Ignore option. These rules will be ignored temporarily, for the current buffer only.

Corrections

Suggestions from LanguageTool can be applied with:

flymake-languagetool-correct: select error in current buffer with completing read

flymake-languagetool-correct-at-point: correct error at point

flymake-languagetool-correct-dwim: if point is on a flymake-languagetool error then correct; otherwise, select one from the current buffer.
