Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:

How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: [email protected]:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

"""

A simple example pyside app that demonstrates dragging and dropping
of files onto a GUI. 

- This app allows dragging and dropping of an image file 
that this then displayed in the GUI
- Alternatively an image can be loaded using the button
- This app includes a workaround for using pyside for dragging and dropping
