GitHub collapse in comment

A userscript that adds a header that can toggle long code and quote blocks in comments

• The block header:
  • Allows the toggling of the long code & quote block views.
  • Includes the code language based on the syntax highlighting class name; if highlighting is not applied, "Block" is used as the default name.
  • Includes the number of lines within the block.
  • Click the header to toggle the view of the content immediately below the header.
  • Use Shift + Click to toggle all the view of all blocks within the same issue comment.
  • Use Shift + (Ctrl or ⌘) + Click to toggle all blocks on the page.
• Can be used along with the GitHub-collapse-markdown userscript.
• Use the userscript addon to change these settings (see screenshot below):
  • "Set GitHub Collapse in Comment Max Lines" to the number of lines within a block needed to add a header (set to 10 by default).
  • "Set GitHub Collapse in Comment Initial State" to expanded to not have the blocks initially collapsed (collapsed by default).
  • After changing either option, make sure to reload the page (Shift + F5) to have the updated setting take effect.
• Click this link to install from GitHub; or, install from GreasyFork or OpenUserJS.
• Or, you can install it as a browser addon. Check out Octopatcher!
