When it comes to sharing code repositories and collaborating on code, Github is one of the most popular platforms. Essentially, Github is a source code management tool that lets users track, manage, and control distributed versions.

Generally speaking, Github works perfectly, but sometimes it can experience errors. It is a common problem when .gitignore stops working. We will explore ways to resolve this problem in this article

What causes .gitignore not to Work?

Your .gitignore feature might work perfectly, but it might not have been configured correctly. A lot of the reasons why coders are having trouble using the feature are either due to improper configuration of the file or because some conditions aren't being met in the underlying code.

Here are a few solutions that might work for you. You might not be able to apply each solution to your case, so proceed to the next if the initial conditions are not met.

Keeping the Git Cache up-to-date with Gitignore changes

In order for the Git cache to reflect your changes, you must update the Gitignore file. To accomplish this, use the "git add" command.

You can update the Git cache with the following command

git add .gitignore

How to fix gitignore not working

1. Verify the encoding of the file

It is necessary to have ANSI coding in your .gitignore file. Notepad saves files in UNICODE format by default. This may prevent the file from working. Here are the steps you can take to resolve this issue

Step 1: Once you've written your .gitignore file, click File, followed by Save As...

Step 2: Set the Encoding dropdown to ANSI. The Save as type dropdown should have All Files (*.*) selected.

Make sure the file works now by testing it using Git.

2. Examining the file that you want to ignore

It is also important that your file has not yet been incorporated into the repository for .gitignore to work. This is an important aspect since, if true, the file won't be ignored since it's already in the repository. Even if you put its name or rule in the .gitignore file, Git cannot ignore that. Therefore, Git ignores untracked files only.

It would be wise for you to check your repository structure (structure) and make sure that the file you are attempting to ignore has not been added to it. This means removing the file from the repository and adding its name to .gitignore after it has been updated (or copy the contents and rename it after deleting).

3. Issues related to Gitignore patterns' case sensitivity

Gitignore treats File.txt and File.txt differently due to its case-sensitivity. Due to their case-insensitive file systems, Windows and macOS do not support Gitignore.

You can use git config to change the core.ignorecase option to false in Gitignore patterns to eliminate case sensitivity:

git config core.ignorecase false

Conclusion

In this post, we explored various scenarios where gitignore wasn't working properly as expected and explored possible solutions. The main takeaway is that you must know where the files/directories are located before adding them.
