Ubuntu – How to create a new file

Please try:

gksudo gedit /usr/bin/conky-start.sh

Write the contents of the file and you should be able to save it. To make it executable, you may need to do:

sudo chmod +x /usr/bin/conky-start.sh

This plugin is written for Python 2, but since gedit 3.8, only Python 3 plugins are supported. So some small changes are required.

1. Modify the installer (gedit-markdown.sh) to install the python3 markdown module:

   This is a patch that you can apply on the existing file (or you can just copy the full modified version available here):

2. Run ./gedit-markdown.sh install

   You should see python 3.4 instead of 2.7:

   ############################################################
   ##
   ## Installation of gedit-markdown
   ##
   ############################################################
   
   ## First step: check dependencies
   
   - gedit: 3.10.4
   - Python: 3.4
   
   [...]
   

3. Change the plugin loader to python3

   Replace /home/aarold/.local/share/gedit/plugins/markdown-preview.plugin with:

   [Plugin]
   Loader=python3
   Module=markdown-preview
   IAge=3
   Name=Markdown Preview
   Name[fr]=Aperçu Markdown
   Description=Show the HTML version of the Markdown text you're editing
   Description[fr]=Affiche l'aperçu en HTML du document Markdown en cours d'édition

4. Convert /home/aarold/.local/share/gedit/plugins/markdown-preview/__init__.py to python3:

   Run:

   2to3 -w /home/aarold/.local/share/gedit/plugins/markdown-preview/__init__.py
   

   Finally open this file and edit line 86 (remove the binary mode, "wb" -> "w"):

   with open(confFile, "w") as confFile:
   

5. Activate the plugin in Gedit as you did.
