Tiny go server that serves a custom api endpoint for shields.io to embed openHPI related badges on the web.

go get github.com/romnn/open-hpi-badge/cmd/openhpibadge

You can also download pre built binaries from the releases page, or use the docker image:

docker pull romnn/openhpibadge

For a list of options, run with --help.

There are a few options for deploying your endpoint:

1. Running the binary

   go build github.com/romnn/open-hpi-badge/cmd/openhpibadge
   ./openhpibadge --port 8080 --prod

   You can also download pre built binaries from the releases page

2. Using docker

   docker run -p 8080:8080 romnn/open-hpi-badge --port 8080 --prod

https://img.shields.io/endpoint?url=...&style=...

The package can also be imported as a library that exports the core functionality to build your more custom endpoint or service.

import github.com/romnn/open-hpi-badge

For example, you can scrape an openHPI mooc by URL:

course, err := openhpibadge.ScrapeMOOCByURL("https://open.hpi.de/courses/neuralnets2020")
if err != nil {
    panic(err)
}
fmt.Println(course.Participants.Current)

course, err := openhpibadge.ScrapeMOOCByName("neuralnets2020")
if err != nil {
    panic(err)
}
fmt.Println(course.Participants.Current)

Before you get started, make sure you have installed the following tools::

$ python3 -m pip install -U cookiecutter>=1.4.0
$ python3 -m pip install pre-commit bump2version invoke ruamel.yaml halo
$ go get -u golang.org/x/tools/cmd/goimports
$ go get -u golang.org/x/lint/golint
$ go get -u github.com/fzipp/gocyclo
$ go get -u github.com/mitchellh/gox  # if you want to test building on different architectures

Remember: To be able to excecute the tools downloaded with go get, make sure to include $GOPATH/bin in your $PATH. If echo $GOPATH does not give you a path make sure to run (export GOPATH="$HOME/go" to set it). In order for your changes to persist, do not forget to add these to your shells .bashrc.

With the tools in place, it is strongly advised to install the git commit hooks to make sure checks are passing in CI:

invoke install-hooks

You can check if all checks pass at any time:

invoke pre-commit

Note for Maintainers: After merging changes, tag your commits with a new version and push to GitHub to create a release:

bump2version (major | minor | patch)
git push --follow-tags

Developers who want to add or update translations can follow these steps:

cd cmd/openhpibadge
# Update the english ones as you wish and eventually sync them
goi18n extract -outdir intn
# This creates a translate.*.toml with all untranslated messages
goi18n merge -outdir intn intn/active.*.toml
# Merges the translate.*.toml back into the active.*.toml
goi18n merge -outdir intn intn/active.*.toml intn/translate.*.toml
# Stores the files as binary assets
go-bindata intn/
