def Lake.noBuildCode : Lake.ExitCode

Exit code to return if --no-build is set and a build is required.

Equations

• Lake.noBuildCode = 3

structure Lake.BuildConfig : Type

Configuration options for a Lake build.

• oldMode : Bool
• trustHash : Bool
• noBuild : Bool

  Early exit if a target has to be rebuilt.

• verbosity : Lake.Verbosity
• failLv : Lake.LogLevel

  Fail the top-level build if entries of at least this level have been logged.

  Unlike some build systems, this does NOT convert such log entries to errors, and it does not abort jobs when warnings are logged (i.e., dependent jobs will still continue unimpeded).

• out : Lake.OutStream

  The stream to which Lake reports build progress. By default, Lake uses stderr.

• ansiMode : Lake.AnsiMode

  Whether to use ANSI escape codes in build output.

def Lake.BuildConfig.outLv (cfg : Lake.BuildConfig) : Lake.LogLevel

The minimum log level for an log entry to be reported.

Equations

• cfg.outLv = cfg.verbosity.minLogLv

def Lake.BuildConfig.showProgress (cfg : Lake.BuildConfig) : Bool

Whether the build should show progress information.

Verbosity.quiet hides progress and, for a noBuild, Verbosity.verbose shows progress.

Equations

• cfg.showProgress = decide (cfg.noBuild = true ∧ (cfg.verbosity == Lake.Verbosity.verbose) = true ∨ (cfg.verbosity != Lake.Verbosity.quiet) = true)

opaque Lake.OpaqueJob.nonemptyType : NonemptyType

instance Lake.instNonemptyOpaqueJob : Nonempty Lake.OpaqueJob

Equations

• Lake.instNonemptyOpaqueJob = ⋯

def Lake.OpaqueJob : Type

A Lake job with an opaque value type in Type.

Equations

• Lake.OpaqueJob = Lake.OpaqueJob.nonemptyType.type

structure Lake.BuildContextextends Lake.BuildConfig , Lake.Context : Type

A Lake context with a build configuration and additional build data.

• oldMode : Bool
• trustHash : Bool
• noBuild : Bool
• verbosity : Lake.Verbosity
• failLv : Lake.LogLevel
• out : Lake.OutStream
• ansiMode : Lake.AnsiMode
• opaqueWs : Lake.OpaqueWorkspace
• leanTrace : Lake.BuildTrace
• registeredJobs : IO.Ref (Array Lake.OpaqueJob)

@[inline, deprecated]

def Lake.logStep {m : Type → Type u_1} [Monad m] [Lake.MonadLog m] (message : String) : m Unit

Logs a build step with message.

Deprecated: Build steps are now managed by a top-level build monitor. As a result, this no longer functions the way it used to. It now just logs the message via logVerbose.

Equations

• Lake.logStep message = Lake.logVerbose message
