Grep Front End code for grep.metacpan.org

grep.metacpan.org is currently not using metacpan-developer, but it should be pretty straight forward to setup a development environment and starting submitting Pull Request via GitHub.

• docker & docker compose
• checkout a version of metacpan-extracted view details after to use metacpan-cpan-extracted-lite

You should start forking the main metacpan-grep-front-end repository You can then clone it locally (where you should replace YOUR-GITHUB-USERNAME by your github username )

> git clone git@github.com:~YOUR-GITHUB-USERNAME~/metacpan-grep-front-end.git
> cd metacpan-grep-front-end
> git remote add upstream https://github.com/metacpan/metacpan-grep-front-end.git

The frontend is not using a database, but a git repo itself as a backend. For this the production is using one huge git repository (~20 Go) indexing all the CPAN in one place ! You can read more on this topic and find tools used to build this Git repo on the GitHub Repos page.

We do not want to use such a beast during development cycles, we only need a smaller version of it, you can simply clone it from this metacpan-cpan-extracted-lite. It should be clone at the same level of metacpan-grep-front-end itself (do not clone it inside the repository).

# clone at the same level of metacpan-grep-front-end
# cd .. # if you are in metacpan-grep-front-end repo
> git clone https://github.com/metacpan/metacpan-cpan-extracted-lite.git

# you should have something like this
> ls -d metacpan-*
metacpan-cpan-extracted-lite metacpan-grep-front-end

> make # alias to `make up` or `make up-dev`

This will start a docker container setup by docker-compose.yml using by default the development environment.

You can now open your browser to this url, and you should be able to see the grep.metacpan.org homepage.

Each environment comes with its own environment, by default they all use values from the default configuration config.yml, but they can overwrite some values or provide some custom values using their own file.

config.yml
environments/development.yml
environments/metacpan.yml
environments/production.yml

If you need two tweak your development environment you should look at environments/development.yml You can even create your own environment if required.

From there you should be ready to

# hack, hack, hack...
-> Submit a Pull Request to GitHub
# continue to hack, hack, ...
have fun !
