Last updated January 26, 2018
Table of Contents
The Dev Center CLI lets authors edit and preview Dev Center articles locally.
Set up Ruby on your local machine. Then install the Dev Center CLI gem:
$ gem install devcenter
Pull your article
Download a local copy of an article with
devcenter pull followed by the article URL:
$ devcenter pull https://devcenter.heroku.com/articles/dev-center-cli "Dev Center CLI" article saved as ~/.../dev-center-cli.md
This will save a
dev-center-cli.md text file in your local directory.
Edit and preview locally
Open the file with your text editor: you will see that the file includes some metadata followed by the article content in markdown format.
The following command will open a preview in your default browser:
$ devcenter preview dev-center-cli Live preview for error-pages available in http://127.0.0.1:3000/dev-center-cli It will refresh when you save ~/.../dev-center-cli.md Press Ctrl+C to exit...
Now start editing the article’s content: the preview will auto-refresh whenever you save the file, so you can see the content you’re editing and its preview side by side.
The markdown file includes some metadata fields. You can edit
title, but never overwrite the
id field: you’ll need it to save your changes in Dev Center.
Stop the preview
To stop the
preview command, press Ctrl+C.
Save the article to Dev Center
Save your local changes to Dev Center using the
devcenter push command:
$ devcenter push dev-center-cli.md
Your local heroku account will be used to push the article. Use
heroku auth:whoami to see which account will be used to push the article and
heroku auth:login if you need to login with a different account.
Get a list of all the available commands with:
$ devcenter help
To get help for a specific command and its available options, e.g:
$ devcenter help preview
