A Mattermost theme generator for themer.
Install this module wherever you have themer installed:
npm install themer-mattermost
Then pass themer-mattermost as a -t (--template) arg to themer:
themer -c my-colors.js -t themer-mattermost -o gen --code-theme monokai
Note that you can select the specific code theme used. Currently the only valid options are solarized-dark, solarized-light, github, and monokai.
