This PR avoids an issue where, through other potential bugs, constants
that are tracked by `Kernel.Environment` but not `Environment` are not
persisted.
This PR adds the `--setup` option to the `lean` CLI. It takes a path to
a JSON file containing information about a module's imports and
configuration, superseding that in the module's own file header. This
will be used by Lake to specify paths to module artifacts (e.g., oleans
and ileans) separate from the `LEAN_PATH` schema.
To facilitate JSON serialization of the header data structure, `NameMap`
JSON instances have been added to core, and `LeanOptions` now makes use
of them.
This PR adds support for the following import variants to the
experimental module system:
* `private import`: Makes the imported constants available only in
non-exported contexts such as proofs. In particular, the import will not
be loaded, or required to exist at all, when the current module is
imported into other modules.
* `import all`: Makes non-exported information such as proofs of the
imported module available in non-exported contexts in the current
module. Main purpose is to allow for reasoning about imported
definitions when they would otherwise be opaque. TODO: adjust name
resolution so that imported `private` decls are accessible through
syntax.
They can be combined into `private import all`, which will likely be the
most common usage of `import all`.
This PR makes `realizeConst` to not set a `declPrefix`. This allows the
realization of both `foo.eq_def` and `bar.eq_def`, where `foo` and `bar`
are mutually recursive, all attached to the same function's environment.
This PR ensures that for modules opted into the experimental module
system, we do not import module docstrings or declaration ranges.
Excluding declaration docstrings as well would require some more work to
make `[inherit_doc]` leave a mere reference to the other declaration
instead of copying its docstring eagerly.
Makes the elaborator constant map truly independent of the kernel's in
preparation for the module system where declarations in the elab env may
in fact differ from the kernel env.
This PR adds a function hook `PersistentEnvExtension.saveEntriesFn` that
can be used to store server-only metadata such as position information
and docstrings that should not affect (re)builds.
This PR fixes an issue where editing a Lean file may lead to a server
deadlock from threadpool starvation, especially on machines with a low
number of cores.
* avoid `panic!`s that return `Unit` or some otherwise unused value lest
they get optimized away
* make some fallback values explicit to avoid follow-up errors
* avoid redundant declaration names in panic messages
This PR introduces the central parallelism API for ensuring that helper
declarations can be generated lazily without duplicating work or
creating conflicts across threads.
This PR moves away from using `List.get` / `List.get?` / `List.get!` and
`Array.get!`, in favour of using the `GetElem` mediated getters. In
particular it deprecates `List.get?`, `List.get!` and `Array.get?`. Also
adds `Array.back`, taking a proof, matching `List.getLast`.
