|
||
This is a starting point for C solutions to the | ||
["Build Your Own Git" Challenge](https://codecrafters.io/challenges/git). | ||
|
||
In this challenge, you'll build a small Git implementation that's capable of | ||
initializing a repository, creating commits and cloning a public repository. | ||
Along the way we'll learn about the `.git` directory, Git objects (blobs, | ||
commits, trees etc.), Git's transfer protocols and more. | ||
|
||
**Note**: If you're viewing this repo on GitHub, head over to | ||
[codecrafters.io](https://codecrafters.io) to try the challenge. | ||
|
||
# Passing the first stage | ||
|
||
The entry point for your Git implementation is in `app/main.c`. Study and | ||
uncomment the relevant code, and push your changes to pass the first stage: | ||
|
||
```sh | ||
git commit -am "pass 1st stage" # any msg | ||
git push origin master | ||
``` | ||
|
||
That's all! | ||
|
||
# Stage 2 & beyond | ||
|
||
Note: This section is for stages 2 and beyond. | ||
|
||
1. Ensure you have `gcc` installed locally | ||
1. Run `./your_program.sh` to run your Git implementation, which is implemented | ||
in `app/main.c`. | ||
1. Commit your changes and run `git push origin master` to submit your solution | ||
to CodeCrafters. Test output will be streamed to your terminal. | ||
|
||
# Testing locally | ||
|
||
The `your_program.sh` script is expected to operate on the `.git` folder inside | ||
the current working directory. If you're running this inside the root of this | ||
repository, you might end up accidentally damaging your repository's `.git` | ||
folder. | ||
|
||
We suggest executing `your_program.sh` in a different folder when testing | ||
locally. For example: | ||
|
||
```sh | ||
mkdir -p /tmp/testing && cd /tmp/testing | ||
/path/to/your/repo/your_program.sh init | ||
``` | ||
|
||
To make this easier to type out, you could add a | ||
[shell alias](https://shapeshed.com/unix-alias/): | ||
|
||
```sh | ||
alias mygit=/path/to/your/repo/your_program.sh | ||
|
||
mkdir -p /tmp/testing && cd /tmp/testing | ||
mygit init | ||
``` |
