jcubic/coverage.el

View on github

coverage.el

Emacs minor mode for displaying code coverage.

Supporting Languages:

  • jest JavaScript framework (also with TypeScript using ts-jest) require running jest --coverage,
  • phpunit xml file generated using coverage-clover option.

Requirement

Highlight.el by Drew Adams

plus default xml and json packages

Limitations

It only work for git controlled repositories (it take root git directory out of git shell command and use this to get coverage file in coverage directory).

Usage

(require 'coverage)

then run

M-x coverage-mode

Enabling the mode is very slow, if your JavaScript source file is big. To refresh the view after made changes to coverage file you can call M-x jc/mark-buffer.

To change colors

;; if you're using light theme
(face-spec-set 'jc/covered '((t :background "light green")))
(face-spec-set 'jc/not-covered '((t :background "light red")))
