spl:deps

Introduction

spl:deps shows what a feature requires according to the constraints of a model. It follows them transitively, so you get every feature a product must also select, not only the direct ones.

splent spl:deps confirmemail sample_splent_spl

SPL deps
SPL      : sample_splent_spl
UVL      : /workspace/.splent_cache/spls/sample_splent_spl@v4/sample_splent_spl.uvl
Features : 17

Dependencies of 'confirmemail' (features it requires):
- auth
- mail

The feature comes first, then the line.

Finding what requires a feature

splent spl:deps auth sample_splent_spl --reverse

Reverse dependencies of 'auth' (features that require it):
- admin
- confirmemail
- profile
- reset

Check it before you remove a feature. - (none) means the feature requires nothing or, with --reverse, that nothing requires it.

Advanced

Only simple constraints of the form a => b are followed. A compound one such as a => b & c is left out, so check those in the model itself.

Reference

`<feature>`	The feature’s name in the model, or its package

A name the model does not have exits 1 with '<feature>' is not a feature of <spl>. and a Did you mean ...? line when one is close.

Requirements
