Lean binary distribution
|
|
------------------------
|
|
|
|
The binary distribution package contains:
|
|
|
|
- Lean executable (located in the sub-directory bin)
|
|
- Standard library (located in the sub-directory lib/lean/library)
|
|
- HoTT library (located in the sub-directory lib/lean/hott)
|
|
- Emacs modes (located in the sub-directory share/emacs/site-list/lean)
|
|
|
|
Assuming you are in the same directory this file is located,
|
|
the following command executes a simple set of examples
|
|
|
|
% bin/lean examples/ex.lean
|
|
|
|
The Emacs mode is the ideal way to use Lean. It requires at
|
|
least Emacs version 24.3
|
|
|
|
Command line options
|
|
--------------------
|
|
|
|
Here are some useful commands for users that do not want to use Emacs,
|
|
or prefer command line tools.
|
|
|
|
- `-T` do not type check imported .olean files
|
|
|
|
% bin/lean -T examples/ex.lean
|
|
|
|
The option can save you a significant amount of time if you are importing
|
|
many files. Lean still checks the check-sum of the imported files.
|
|
So, it still can detect trivial tempering of the .olean files.
|
|
|
|
- `-c [file.clean]` create/use a cache file. This option can increase the
|
|
compilation time of large files when we are invoking Lean many times
|
|
with small incremental changes.
|
|
|
|
% bin/lean -c ex.clean examples/ex.lean
|
|
|
|
- `--deps` display files imported by a given Lean file. This option
|
|
is useful if you want to build your own custom Makefile.
|
|
|
|
% bin/lean --deps examples/ex.lean
