Lean.Parser.Command.eval : command`#eval e` evaluates the expression `e` by compiling and evaluating it. * The command attempts to use `ToExpr`, `Repr`, or `ToString` instances to print the result. * If `e` is a monadic value of type `m ty`, then the command tries to adapt the monad `m` to one of the monads that `#eval` supports, which include `IO`, `CoreM`, `MetaM`, `TermElabM`, and `CommandElabM`. Users can define `MonadEval` instances to extend the list of supported monads. The `#eval` command gracefully degrades in capability depending on what is imported. Importing the `Lean.Elab.Command` module provides full capabilities. Due to unsoundness, `#eval` refuses to evaluate expressions that depend on `sorry`, even indirectly, since the presence of `sorry` can lead to runtime instability and crashes. This check can be overridden with the `#eval! e` command. Options: * If `eval.pp` is true (default: true) then tries to use `ToExpr` instances to make use of the usual pretty printer. Otherwise, only tries using `Repr` and `ToString` instances. * If `eval.type` is true (default: false) then pretty prints the type of the evaluated value. * If `eval.derive.repr` is true (default: true) then attempts to auto-derive a `Repr` instance when there is no other way to print the result. See also: `#reduce e` for evaluation by term reduction.#evalๅฝไปค็็ปๆใ -

nameContains: The package name
ๅ ็ๅ็งฐใ
versionContains: Version string
The package version. Versions have the form:
v!"<major>.<minor>.<patch>[-<specialDescr>]"
A version with a
-suffix is considered a "prerelease".Lake suggest the following guidelines for incrementing versions:
-
Major version increment (e.g., v1.3.0 โ v2.0.0) Indicates significant breaking changes in the package. Package users are not expected to update to the new version without manual intervention.
-
Minor version increment (e.g., v1.3.0 โ v1.4.0) Denotes notable changes that are expected to be generally backwards compatible. Package users are expected to update to this version automatically and should be able to fix any breakages and/or warnings easily.
-
Patch version increment (e.g., v1.3.0 โ v1.3.1) Reserved for bug fixes and small touchups. Package users are expected to update automatically and should not expect significant breakage, except in the edge case of users relying on the behavior of patched bugs.
Note that backwards-incompatible changes may occur at any version increment. The is because the current nature of Lean (e.g., transitive imports, rich metaprogramming, reducibility in proofs), makes it infeasible to define a completely stable interface for a package. Instead, the different version levels indicate a change's intended significance and how difficult migration is expected to be.
Versions of form the
0.x.xare considered development versions prior to first official release. Like prerelease, they are not expected to closely follow the above guidelines.Packages without a defined version default to
0.0.0.-
versionTagsContains: String pattern
Git tags of this package's repository that should be treated as versions. Package indices (e.g., Reservoir) can make use of this information to determine the Git revisions corresponding to released versions.
Defaults to tags that are "version-like". That is, start with a
vfollowed by a digit.descriptionContains: String
A short description for the package (e.g., for Reservoir).
keywordsContains: Array of strings
Custom keywords associated with the package. Reservoir can make use of a package's keywords to group related packages together and make it easier for users to discover them.
Good keywords include the domain (e.g.,
math,software-verification,devtool), specific subtopics (e.g.,topology,cryptology), and significant implementation details (e.g.,dsl,ffi,cli). For instance, Lake's keywords could bedevtool,cli,dsl,package-manager, andbuild-system.homepageContains: String
A URL to information about the package.
Reservoir will already include a link to the package's GitHub repository (if the package is sourced from there). Thus, users are advised to specify something else for this (if anything).
licenseContains: String
The package's license (if one). Should be a valid SPDX License Expression.
Reservoir requires that packages uses an OSI-approved license to be included in its index, and currently only supports single identifier SPDX expressions. For, a list of OSI-approved SPDX license identifiers, see the SPDX LIcense List.
licenseFilesContains: Array of paths
Files containing licensing information for the package.
These should be the license files that users are expected to include when distributing package sources, which may be more then one file for some licenses. For example, the Apache 2.0 license requires the reproduction of a
NOTICEfile along with the license (if such a file exists).Defaults to
#["LICENSE"].readmeFileContains: Path
The path to the package's README.
A README should be a Markdown file containing an overview of the package. Reservoir displays the rendered HTML of this file on a package's page. A nonstandard location can be used to provide a different README for Reservoir and GitHub.
Defaults to
README.md.reservoirContains: Boolean
Whether Reservoir should include the package in its index. When set to
false, Reservoir will not add the package to its index and will remove it if it was already there (when Reservoir is next updated).

srcDirContains: Path
The directory containing the package's Lean source files. Defaults to the package's directory.
(This will be passed to
leanas the-Roption.)buildDirContains: Path
The directory to which Lake should output the package's build results. Defaults to
defaultBuildDir(i.e.,.lake/build).nativeLibDirContains: Path
The build subdirectory to which Lake should output the package's native libraries (e.g.,
.a,.so,.dllfiles). Defaults todefaultNativeLibDir(i.e.,lib).binDirContains: Path
The build subdirectory to which Lake should output the package's binary executable. Defaults to
defaultBinDir(i.e.,bin).irDirContains: Path
The build subdirectory to which Lake should output the package's intermediary results (e.g.,
.cand.ofiles). Defaults todefaultIrDir(i.e.,ir).packagesDirContains: Path
The directory to which Lake should download remote dependencies. Defaults to
defaultPackagesDir(i.e.,.lake/packages).

extraDepTargetsContains: Array of strings
An
Arrayof target names to build whenever the package is used.precompileModulesContains: Boolean
Whether to compile each of the package's module into a native shared library that is loaded whenever the module is imported. This speeds up evaluation of metaprograms and enables the interpreter to run functions marked
@[extern].Defaults to

Asserts whether Lake should assume Lean modules are platform-independent.
-
If
false, Lake will addSystem.Platform.targetto the module traces within the code unit (e.g., package or library). This will force Lean code to be re-elaborated on different platforms. -
If
true, Lake will exclude platform-dependent elements (e.g., precompiled modules, external libraries) from a module's trace, preventing re-elaboration on different platforms. Note that this will not effect modules outside the code unit in question. For example, a platform-independent package which depends on a platform-dependent library will still be platform-dependent. -
If
none, Lake will construct traces as natural. That is, it will include platform-dependent artifacts in the trace if they module depends on them, but otherwise not force modules to be platform-dependent.
There is no check for correctness here, so a configuration can lie and Lake will not catch it. Defaults to
none.-

The URL of the GitHub repository to upload and download releases of this package. If
none(the default), for downloads, Lake uses the URL the package was download from (if it is a dependency) and for uploads, usesgh's default.buildArchiveContains: String (optional)
A custom name for the build archive for the GitHub cloud release. If
none(the default), Lake defaults to{(pkg-)name}-{System.Platform.target}.tar.gz.preferReleaseBuildContains: Boolean
Whether to prefer downloading a prebuilt release (from GitHub) rather than building this package from the source when this package is used as a dependency.
Other Fields:
bootstrapContains: Boolean
For internal use. Whether this package is Lean itself.
enableArtifactCacheContains: Boolean (optional)
Whether to enables Lake's local, offline artifact cache for the package.
Artifacts (i.e., build products) of packages will be shared across local copies by storing them in a cache associated with the Lean toolchain. This can significantly reduce initial build times and disk space usage when working with multiple copies of large projects or large dependencies.
As a caveat, build targets which support the artifact cache will not be stored in their usual location within the build directory. Thus, projects with custom build scripts that rely on specific location of artifacts may wish to disable this feature.
If
none(the default), this will fallback to (in order):-
The
LAKE_ARTIFACT_CACHEenvironment variable (if set). -
The workspace root's
enableArtifactCacheconfiguration (if set and this package is a dependency). -
Lake's default: The package can use artifacts from the cache, but cannot write to it.
-
restoreAllArtifactsContains: Boolean (optional)
Whether, when the local artifact cache is enabled, Lake should copy all cached artifacts into the build directory. This ensures the build results are available to external consumers who expect them in the build directory.
If
none(the default), this will fallback to (in order):-
The
LAKE_RESTORE_ARTIFACTSenvironment variable (if set). -
The workspace root's
restoreAllArtifactsconfiguration (if set and this package is a dependency). -
Lake's default:
false.
-
libPrefixOnWindowsContains: Boolean
Whether native libraries (of this package) should be prefixed with
libon Windows.Unlike Unix, Windows does not require native libraries to start with
liband, by convention, they usually do not. However, for consistent naming across all platforms, users may wish to enable this.Defaults to
false.allowImportAllContains: Boolean
Whether downstream packages can
import allmodules of this package.If enabled, downstream users will be able to access the
privateinternals of modules, including definition bodies not marked as@[expose]. This may also, in the future, prevent compiler optimization which rely onprivatedefinitions being inaccessible outside their own package.Defaults to
false.fixedToolchainContains: Boolean
Whether this package is expected to function only on a single toolchain (the package's toolchain).
This informs Lake's toolchain update procedure (in
lake update) to prioritize this package's toolchain. It also avoids the need to separate input-to-output mappings for this package by toolchain version in the Lake cache.Defaults to
false.moreLinkObjsContains: Array of paths
Additional target objects to use when linking (both static and shared). These will come after the paths of native facets.
moreLinkLibsContains: Array of dynamic libraries
Additional target libraries to pass to
leancwhen linking (e.g., for shared libraries or binary executables). These will come after the paths of other link objects.

ไฝฟ็จ Lake.DSL.requireDecl : commandAdds a new package dependency to the workspace. The general syntax is:
```
require ["<scope>" /] <pkg-name> [@ <version>]

```
The `from` clause tells Lake where to locate the dependency.
See the `fromClause` syntax documentation (e.g., hover over it) to see
the different forms this clause can take.
Without a `from` clause, Lake will lookup the package in the default
registry (i.e., Reservoir) and use the information there to download the
package at the requested `version`. The `scope` is used to disambiguate between
packages in the registry with the same `pkg-name`. In Reservoir, this scope
is the package owner (e.g., `leanprover` of `@leanprover/doc-gen4`).
The `with` clause specifies a `NameMap String` of Lake options
used to configure the dependency. This is equivalent to passing `-K`
options to the dependency on the command line.

The subdirectory of the package's source directory containing the library's
Lean source files. Defaults simply to said srcDir.
(This will be passed to lean as the -R option.)
roots : Array Lean.Name
The root module(s) of the library.
Submodules of these roots (e.g., Lib.Foo of Lib) are considered
part of the library.
Defaults to a single root of the target's name.
globs : Array Lake.Glob
An Array of module Globs to build for the library.
Defaults to a Glob.one of each of the library's roots.
Submodule globs build every source file within their directory. Local imports of glob'ed files (i.e., fellow modules of the workspace) are also recursively built.
libName : String
The name of the library artifact. Used as a base for the file names of its static and dynamic binaries. Defaults to the mangled name of the target.
libPrefixOnWindows : Bool
Whether static and shared binaries of this library should be prefixed with lib on Windows.
Unlike Unix, Windows does not require native libraries to start with lib and,
by convention, they usually do not. However, for consistent naming across all platforms,
users may wish to enable this.
Defaults to false.
needs : Array Lake.PartialBuildKey
An Array of targets to build before the executable's modules.
extraDepTargets : Array Lean.Name
Deprecated. Use needs instead.
An Array of target names to build before the library's modules.
precompileModules : Bool
defaultFacets : Array Lean.Name
An Array of library facets to build on a bare lake build of the library.
For example, #[LeanLib.sharedFacet] will build the shared library facet.
nativeFacets : Bool โ Array (Lake.ModuleFacet System.FilePath)
The module facets to build and combine into the library's static
and shared libraries. If shouldExport is true, the module facets should
export any symbols a user may expect to lookup in the library. For example,
the Lean interpreter will use exported symbols in linked libraries.
Defaults to a singleton of Module.oExportFacet (if shouldExport) or
Module.oFacet. That is, the object files compiled from the Lean sources,
potentially with exported Lean symbols.
allowImportAll : Bool
Whether downstream packages can import all modules of this library.
If enabled, downstream users will be able to access the private internals of modules,
including definition bodies not marked as @[expose].
This may also, in the future, prevent compiler optimization which rely on private
definitions being inaccessible outside their own package.
Defaults to false.

supportInterpreter : Bool
Enables the executable to interpret Lean files (e.g., via
Lean.Elab.runFrontend) by exposing symbols within the executable
to the Lean interpreter.
Implementation-wise, on Windows, the Lean shared libraries are linked
to the executable and, on other systems, the executable is linked with
-rdynamic. This increases the size of the binary on Linux and, on Windows,
requires libInit_shared.dll and libleanshared.dll to be co-located
with the executable or part of PATH (e.g., via lake exe). Thus, this
feature should only be enabled when necessary.
Defaults to false.
nativeFacets : Bool โ Array (Lake.ModuleFacet System.FilePath)
The module facets to build and combine into the executable.
If shouldExport is true, the module facets should export any symbols
a user may expect to lookup in the executable. For example, the Lean
interpreter will use exported symbols in the executable. Thus, shouldExport
will be true if supportInterpreter := true.
Defaults to a singleton of Module.oExportFacet (if shouldExport) or
Module.oFacet. That is, the object file compiled from the Lean source,
potentially with exported Lean symbols.

inductive type
Lake equivalent of CMake's
CMAKE_BUILD_TYPE.
Constructors
Lake.BuildType.debug : Lake.BuildType
Debug optimization, asserts enabled, custom debug code enabled, and
debug info included in executable (so you can step through the code with a
debugger and have address to source-file:line-number translation).
For example, passes -O0 -g when compiling C code.
Lake.BuildType.relWithDebInfo : Lake.BuildType
Optimized, with debug info, but no debug code or asserts
(e.g., passes -O3 -g -DNDEBUG when compiling C code).
Lake.BuildType.minSizeRel : Lake.BuildType
Same as release but optimizing for size rather than speed
(e.g., passes -Os -DNDEBUG when compiling C code).
Lake.BuildType.release : Lake.BuildType
High optimization level and no debug info, code, or asserts
(e.g., passes -O3 -DNDEBUG when compiling C code).
