Usage: leanpkg <command>

||
|
||
init <name> create a Lean package in the current directory
|
||
configure download and build dependencies
|
||
build [<args>] configure and build *.olean files

|
||
See `leanpkg help <command>` for more information on a specific command."

|
||
|
||
Usage:
|
||
leanpkg configure
|
||
|
||
This command sets up the `build/deps` directory.
|
||
|
||
For each (transitive) git dependency, the specified commit is checked out
|
||
into a sub-directory of `build/deps`. If there are dependencies on multiple
|
||
versions of the same package, the version materialized is undefined. No copy
|
||
is made of local dependencies."

def helpBuild :=
|

"Download dependencies and build *.olean files
|
||
|
||
Usage:
|
||
leanpkg build [<leanmake-args>] [-- <lean-args>]
|
||
|
||
This command invokes `leanpkg configure` followed by `leanmake <leanmake-args> LEAN_OPTS=<lean-args>`.
|
||
If defined, the `package.timeout` configuration value is passed to Lean via its `-T` parameter.
|
||
If no <lean-args> are given, only .olean files will be produced in `build/`. If `lib` or `bin`
|
||
is passed instead, the extracted C code is compiled with `c++` and a static library in `build/lib`
|
||
or an executable in `build/bin`, respectively, is created. `leanpkg build bin` requires a declaration
|
||
of name `main` in the root namespace, which must return `IO Unit` or `IO UInt32` (the exit code) and
|
||
may accept the program's command line arguments as a `List String` parameter.
|
||
|
||
NOTE: building and linking dependent libraries currently has to be done manually, e.g.
|
||
```
|
||
$ (cd a; leanpkg build lib)
|
||
$ (cd b; leanpkg build bin LINK_OPTS=../a/build/lib/libA.a)
|
||
```"

leanpkg init <name>
