NOTE: Vantablack is currently a work-in-progress (pre-1.0). Both the implementation and its documentation are still in development. They are both subject to change without notice and may not be consistent with each other.
Vantablack is an extendable linter for validating StepMania songs and song packs. It can be used to automatically validate songs and song packs against a configurable list of rules.
Examples of rules include:
- Detecting
.oldfiles generated by the StepMania editor in song folders for removal before chart distribution. - Detecting songs with missing or incorrectly-sized graphics.
- Enforcing a maximum length for the audio file.
Add a vantablack.toml file to your pack root.
For example:
Song Pack/
├─ vantablack.toml
├─ banner.png
├─ Song 1/
├─ Song 2/
└─ ...
This is a TOML file that describes the set of rules to run against your pack.
Here's an example vantablack.toml
vantablack.version = 0
[vantablack.rules]
# For every chart in an ssc file, assert that its credit has the value "bkirz".
ssc_chart.require_credit.value = "bkirz"
# Fail if any song is missing a jacket, background, or banner, or if any of those graphics have the wrong dimensions.
song.background.dimensions = { width = 1366, height = 768 }
song.banner.dimensions = { width = 418, height = 164 }
song.jacket.dimensions = { width = 512, height = 512 }
# All files within song directories should be directly referenced by a .ssc file.
song.no_extra_files.enabled = true
# Fail if any songs are missing a challenge chart.
song.require_difficulty.difficulty = 'Challenge'
song.require_difficulty.style = 'dance-single'
# Fail if any non-4-panel charts are included
chart.restrict_field.field = 'STEPSTYPE'
chart.restrict_field.value = 'dance-single'
# Fail if any charts have no notes
chart.fail_on_empty.enabled = true
