DSL for Targets & Facets

Macros for declaring Lake targets and facets.

def Lake.DSL.buildDeclSig : Lean.ParserDescr

Equations

• One or more equations did not get rendered due to their size.

Facet Declarations

def Lake.DSL.moduleFacetDecl : Lean.ParserDescr

Define a new module facet. Has one form:

module_facet «facet-name» (mod : Module) : α :=
  /- build term of type `IndexBuildM (BuildJob α)` -/

The mod parameter (and its type specifier) is optional.

Equations

• One or more equations did not get rendered due to their size.

def Lake.DSL.packageFacetDecl : Lean.ParserDescr

Define a new package facet. Has one form:

package_facet «facet-name» (pkg : Package) : α :=
  /- build term of type `IndexBuildM (BuildJob α)` -/

The pkg parameter (and its type specifier) is optional.

Equations

• One or more equations did not get rendered due to their size.

def Lake.DSL.libraryFacetDecl : Lean.ParserDescr

Define a new library facet. Has one form:

library_facet «facet-name» (lib : LeanLib) : α :=
  /- build term of type `IndexBuildM (BuildJob α)` -/

The lib parameter (and its type specifier) is optional.

Equations

• One or more equations did not get rendered due to their size.

Custom Target Declaration

def Lake.DSL.targetDecl : Lean.ParserDescr

Define a new custom target for the package. Has one form:

target «target-name» (pkg : NPackage _package.name) : α :=
  /- build term of type `IndexBuildM (BuildJob α)` -/

The pkg parameter (and its type specifier) is optional. It is of type NPackage _package.name to provably demonstrate the package provided is the package in which the target is defined.

Equations

• One or more equations did not get rendered due to their size.

Lean Library & Executable Target Declarations

def Lake.DSL.leanLibDecl : Lean.ParserDescr

Define a new Lean library target for the package. Can optionally be provided with a configuration of type LeanLibConfig. Has many forms:

lean_lib «target-name»
lean_lib «target-name» { /- config opts -/ }
lean_lib «target-name» where /- config opts -/
lean_lib «target-name» := /- config -/

Equations

• One or more equations did not get rendered due to their size.

def Lake.DSL.leanExeDecl : Lean.ParserDescr

Define a new Lean binary executable target for the package. Can optionally be provided with a configuration of type LeanExeConfig. Has many forms:

lean_exe «target-name»
lean_exe «target-name» { /- config opts -/ }
lean_exe «target-name» where /- config opts -/
lean_exe «target-name» := /- config -/

Equations

• One or more equations did not get rendered due to their size.

External Library Target Declaration

def Lake.DSL.externLibDeclSpec : Lean.ParserDescr

Equations

• One or more equations did not get rendered due to their size.

def Lake.DSL.externLibDecl : Lean.ParserDescr

Define a new external library target for the package. Has one form:

extern_lib «target-name» (pkg : NPackage _package.name) :=
  /- build term of type `IndexBuildM (BuildJob FilePath)` -/

The pkg parameter (and its type specifier) is optional. It is of type NPackage _package.name to provably demonstrate the package provided is the package in which the target is defined.

The term should build the external library's static library.

Equations

• One or more equations did not get rendered due to their size.
