Package Registries

This module contains definitions for fetching Lake package information from a online registry (e.g., Reservoir).

inductive Lake.RegistrySrc : Type

Package source information from a Lake registry (e.g., Reservoir). Only contains the subset of fields useful to Lake.

• git (data : JsonObject) (url : String) (githubUrl? defaultBranch? : Option String) (subDir? : Option System.FilePath) : RegistrySrc
• other (data : JsonObject) : RegistrySrc

@[implicit_reducible]

instance Lake.instInhabitedRegistrySrc : Inhabited RegistrySrc

Equations

• Lake.instInhabitedRegistrySrc = { default := Lake.instInhabitedRegistrySrc.default }

def Lake.instInhabitedRegistrySrc.default : RegistrySrc

Equations

• Lake.instInhabitedRegistrySrc.default = Lake.RegistrySrc.git default default default default default

def Lake.RegistrySrc.isGit (src : RegistrySrc) : Bool

Equations

• (Lake.RegistrySrc.git data url githubUrl? defaultBranch? subDir?).isGit = true
• (Lake.RegistrySrc.other data).isGit = false

def Lake.RegistrySrc.data (src : RegistrySrc) : JsonObject

Equations

• (Lake.RegistrySrc.git data url githubUrl? defaultBranch? subDir?).data = data
• (Lake.RegistrySrc.other data).data = data

def Lake.RegistrySrc.toJson (src : RegistrySrc) : Lean.Json

Equations

• src.toJson = Lean.Json.obj src.data

@[implicit_reducible]

instance Lake.RegistrySrc.instToJson : Lean.ToJson RegistrySrc

Equations
