Problem

I have a folder structure like:

.gitignore
notebooks/
notebooks/nb1.ipynb
notebooks/nb1_outputs.something
notebooks/folderA/
notebooks/folderA/nb2.ipynb
notebooks/folderA/nb2_outputs.someothers
notebooks/folderA/folderAA/nb3.ipynb
notebooks/folderA/folderAA/nb3_outputs.someothers
...

I want to ignore all stuff in the notebooks/ folder except *.ipynb files.

What I have tried

I wrote in the .gitignore like this:

/notebooks/*
!**.ipynb

but this did not work for nb2.ipynb, probably because it is in a subfolder which has been ignored by /notebooks/*.

Though I can write manually:

/notebooks/*.*
!/notebooks/*.ipynb
/notebooks/*/*.*
!/notebooks/*/*.ipynb
/notebooks/*/*/*.*
!/notebooks/*/*/*.ipynb

Is there a way to do this more easily?

(base) ➜  git-test git:(master) ✗ cat .gitignore

(base) ➜  git-test git:(master) ✗ tree          
.
└── notebooks
    ├── folderA
    │   ├── nb2.ipynb
    │   └── nb2.out
    ├── nb1.ipynb
    └── nb1.out

2 directories, 4 files
(base) ➜  git-test git:(master) ✗ git status    
On branch master

Initial commit

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        .gitignore

nothing added to commit but untracked files present (use "git add" to track)
(base) ➜  git-test git:(master) ✗ git --version
git version 2.7.4

CodePudding user response：

Well I just figured this out. Just write:

# ignore all files in subfolders
/notebooks/**/*.*
# revert for notebooks
!/notebooks/**/*.ipynb

This works for me, though it is still prone to files without extensions.

CodePudding user response：

Use two consecutive asterisks ** (from version 1.8.2) which match any level of subdirectories.

From documentation:

A trailing /** matches everything inside. For example, abc/** matches all files inside directory abc, relative to the location of the .gitignore file, with infinite depth.

Change your .gitignore as follows:

notebooks/**
!notebooks/**/*.ipynb

and anything inside the folder notebook, except the .ipynb files, is ignored.

However, if the .gitignore file only has these two entries, the clean code approach would be to move the .gitignore one herarchy up to the notebooksfolder and simplify it as follows:

notebooks/**
!**/*.ipynb
