Bludit: How to install and configure Gris

January 29, 2020

I have been working on a different UI for the editor, fully integrated with the Bludit API + AJAX, also has some particular integration with tags, full Markdown support, and a color full dark mode.

I started the project for my technical blog but I would like to share the steps to install and configure the themes on your Bludit installation. I recommend to start from scratch Bludit installation and do not overwrite a current configuration until you understand how this is working.

Features:

  • Markdown support.
  • Markdown editor, thanks to EasyMDE.
  • Integrated with highlight.js.
  • Quick view for edit and change properties of the page.
  • UI with AJAX and base on tags.
  • Dark mode.
  • Public and private pages, in the end, the private is just a draft type on Bludit.
  • Ideal for technical people who want to post some code or just add embed code to the pages.

Git: Delete commits history

You can not delete the commit history from a branch, but you can create a new branch (without history because is new), push the files to the new branch and then delete the old branch.

The next example shows how to recreate the master branch.

# Create temporary branch
$ git checkout --orphan temp

# Add and commit all the files
$ git add -A
$ git commit -m "init"

# Delete current branch
$ git branch -D master

# Rename current branch to master
$ git branch -m master

# Push all the files to the new master branch
$ git push -f origin master
