Through the Embed instruction or plugin, Gist snippets on GitHub can conveniently provide posts on Medium, WordPress, and elsewhere supplementary information (lines of code, images, Markdown-created tables, and so on). But while Gist snippets on GitHub can be managed directly via browser or through something like Gisto, a user might also wish to manipulate them offline. This last is for many of the same reasons that a user seeks to clone a git repo to their local filesystem, modify it locally, and then only subsequently push changes back up to GitHub.
Here's how to do this:
Create the gist on GitHub and then clone it to your local filesystem:
$ git clone https://gist.github.com/DannyQuah/5f43f9b75970bc4e357e42c7c9214b5d
Locally, rename that folder however you wish (or just leave it as that long string):
$ mv -i 5f43f9b75970bc4e357e42c7c9214b5d YYYY.MM-Author-Subject
Work on the file inside YYYY.MM-Author-Subject/; and then, whenever ready, as usual do:
$ # changes ...
$ git commit -m "The new changes"
$ git push
You can leave this as above. But you can also get fancier.
Using the feature that a git repo on the local filesystem can be associated with multiple remotes on GitHub, it is possible, alternatively and optionally, to save both a gist and a git repo on GitHub. Doing so follows Ishu3101.
(In the sequel, anything that begins my should be named however the user prefers.)
After the steps, above also create on GitHub a new git repo myGistProject; then from inside YYYY.MM-Author-Subject/ add that new GitHub repo as a remote, labelling it myGitHub for git use, i.e.,
$ git remote add myGithub https://github.com/DannyQuah/myGistProject
Push to the new repository on GitHub
$ git push myGithub main
Keep things parallel by renaming the remote of the Gist snippet: origin is where this had come from, so now instead call it myGist
$ git remote rename origin myGist
Now each time push either to myGithub or myGist (or both, obviously):
$ # changes
$ git commit -m "The new changes"
$ git push myGithub main # to github
$ git push myGist master # to gist
Prosper.
(As far as I have been able to tell gist.github.com continues to use master as the primary branch while since Oct 2020 github.com itself has switched to main.)
