The `PackageFacet` to build on a bare `lake build` of the package.

(i.e., `lean --server`) launched by `lake server`.

The directory containing the package's Lean source files.
Defaults to the package's directory.
(This will be passed to `lean` as the `-R` option.)
-/
srcDir : FilePath := "."
/--
The directory to which Lake should output the package's build results.
Defaults to `defaultBuildDir` (i.e., `build`).

The build subdirectory to which Lake should output the package's `.olean` files.
Defaults to `defaultOleanDir` (i.e., `lib`).
-/
oleanDir : FilePath := defaultOleanDir
/--
The root module(s) of the package's library.
Submodules of these roots (e.g., `Pkg.Foo` of `Pkg`) are considered
part of the package.
Defaults to a single root of the package's upper camel case `name`.
-/
libRoots : Array Name := #[toUpperCamelCase name]
/--
An `Array` of module `Glob`s to build for the package's library.
Defaults to a `Glob.one` of each of the module's `libRoots`.
Submodule globs build every source file within their directory.
Local imports of glob'ed files (i.e., fellow modules of the package) are
also recursively built.

Additional arguments to pass to `lean` while compiling Lean source files.

Additional arguments to pass to `leanc`
while compiling the C source files generated by `lean`.
Lake already passes `-O3` and `-DNDEBUG` automatically,
but you can change this by, for example, adding `-O0` and `-UNDEBUG`.
-/
moreLeancArgs : Array String := #[]
/--
The build subdirectory to which Lake should output
the package's intermediary results (e.g., `.c` and `.o` files).
Defaults to `defaultIrDir` (i.e., `ir`).
-/
irDir : FilePath := defaultIrDir
/--
The name of the package's static library.
Defaults to the package's upper camel case `name`.
-/
libName : String := toUpperCamelCase name |>.toString (escape := false)
/--
The build subdirectory to which Lake should output the package's static library.
Defaults to `defaultLibDir` (i.e., `lib`).
-/
libDir : FilePath := defaultLibDir
/--
The name of the package's binary executable.
Defaults to the package's `name` with any `.` replaced with a `-`.
-/
binName : String := name.toStringWithSep "-" (escape := false)
/--
The build subdirectory to which Lake should output the package's binary executable.
Defaults to `defaultBinDir` (i.e., `bin`).
-/
binDir : FilePath := defaultBinDir
/--
The root module of the package's binary executable.
Defaults to `defaultBinRoot` (i.e., `Main`).
The root is built by recursively building its
local imports (i.e., fellow modules of the package).
This setting is most useful for packages that are distributing both a
library and a binary (like Lake itself). In such cases, it is common for
there to be code (e.g., `main`) that is needed for the binary but should
not be included in the library proper.
-/
binRoot : Name := defaultBinRoot
/--
Additional library `FileTarget`s (beyond the package's and its dependencies'
libraries) to build and link to the package's binary executable (and/or to
dependent package's executables).
-/
moreLibTargets : Array FileTarget := #[]
/--
Whether to expose symbols within the executable to the Lean interpreter.
This allows the executable to interpret Lean files (e.g., via
`Lean.Elab.runFrontend`).
Implementation-wise, this passes `-rdynamic` to the linker when building
on non-Windows systems.
Defaults to `false`.
-/
supportInterpreter : Bool := false
/--
Additional arguments to pass to `leanc` while compiling the package's
binary executable. These will come *after* the paths of libraries built
with `moreLibTargets`.
