DAB+ now playing PAD (DLS+ and MOT SLS) generator

Usage

DL+

You can use this to generate some DLPlus Tags.

>>> from nowplaypadgen.dlplus import *
>>> message = DLPlusMessage()
>>> message.add_dlp_object(DLPlusObject("STATIONNAME.LONG", "Radio Bern RaBe"))
>>> message.add_dlp_object(DLPlusObject("STATIONNAME.SHORT", "RaBe"))
>>> message.add_dlp_object(DLPlusObject("ITEM.TITLE", "Radio Bern"))
>>> message.build("$STATIONNAME.LONG")
>>> message.message
'Radio Bern RaBe'
>>> tags = message.get_dlp_tags()
>>> long = tags['STATIONNAME.LONG']
>>> f"{long}: {long.code} {long.start} {long.length}"
'STATIONNAME.LONG: 32 0 15'
>>> short = tags['STATIONNAME.SHORT']
>>> f"{short}: {short.code} {short.start} {short.length}"
'STATIONNAME.SHORT: 31 11 4'
>>> title = tags['ITEM.TITLE']
>>> f"{title}: {title.code} {title.start} {title.length}"
'ITEM.TITLE: 1 0 10'

Later on you might want to generate DL+ that deletes an item tag.

>>> message = DLPlusMessage()
>>> message.add_dlp_object(DLPlusObject("STATIONNAME.LONG", "Radio Bern RaBe"))
>>> message.add_dlp_object(DLPlusObject("ITEM.TITLE", delete=True))
>>> message.build("$STATIONNAME.LONG")
>>> message.message
'Radio Bern RaBe'
>>> tags = message.get_dlp_tags()
>>> title = tags['ITEM.TITLE']
>>> f"{title}: {title.code} {title.start} {title.length}"
'ITEM.TITLE: 1 5 0'

Finally, you can render it as an ODR-PadEnc style string.

>>> from nowplaypadgen.dlplus import *
>>> message = DLPlusMessage()
>>> message.add_dlp_object(DLPlusObject("ITEM.TITLE", "Radio Bern"))
>>> message.add_dlp_object(DLPlusObject("STATIONNAME.SHORT", "RaBe"))
>>> message.add_dlp_object(DLPlusObject("STATIONNAME.LONG", "Radio Bern RaBe"))
>>> message.build("$STATIONNAME.LONG")
>>> from nowplaypadgen.renderer.odr import ODRPadEncRenderer
>>> renderer = ODRPadEncRenderer(message)

This will generate the following ODR-PadEnc style DLS string when rendered with print(renderer):

##### parameters { #####
DL_PLUS=1
DL_PLUS_TAG=1 0 10
DL_PLUS_TAG=31 11 4
DL_PLUS_TAG=32 0 15
##### parameters } #####
Radio Bern RaBe

Release Management

The CI/CD setup uses semantic commit messages following the conventional commits standard. There is a GitHub Action in .github/workflows/semantic-release.yaml that uses go-semantic-commit to create new releases.

The commit message should be structured as follows:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

The commit contains the following structural elements, to communicate intent to the consumers of your library:

1. fix: a commit of the type fix patches gets released with a PATCH version bump
2. feat: a commit of the type feat gets released as a MINOR version bump
3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE: gets released as a MAJOR version bump
4. types other than fix: and feat: are allowed and don't trigger a release

If a commit does not contain a conventional commit style message you can fix it during the squash and merge operation on the PR.

Once a commit has landed on the main branch a release will be created and automatically published to pypi using the GitHub Action in .github/workflows/pypi.yaml which uses twine to publish the package to pypi.
