* Update Z3_mk_datatype_sort API to accept array of sort parameters and add Z3_mk_polymorphic_datatype (#7966)
* Initial plan
* Update Z3_mk_datatype_sort API to accept array of parameters
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Update language bindings for parametric datatype sort API
- Python: Updated DatatypeSort() to accept optional params list
- OCaml: Added mk_sort_ref_p/mk_sort_ref_ps for parametric datatypes
- .NET: Added MkDatatypeSortRef() methods with optional params
- Java: Added mkDatatypeSortRef() methods with optional params
- All changes maintain backward compatibility
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Fix .NET build error - rename params to parameters
The 'params' keyword is reserved in C#, causing compilation errors.
Renamed parameter from 'params' to 'parameters' in MkDatatypeSortRef methods.
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Add unit test for parametric datatypes
Added test_parametric_datatype.cpp to demonstrate polymorphic datatypes.
The test creates two concrete instantiations of a generic pair concept:
- pair_int_real with fields (first:Int, second:Real)
- pair_real_int with fields (first:Real, second:Int)
Then verifies that accessors work correctly and type checking is enforced.
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Implement polymorphic type variables support for parametric datatypes
- Modified datatype_decl_plugin to allow type variables as parameters
- Updated mk_datatype_decl to extract type variables from field sorts
- Type variables are collected in order of first appearance
- Revised unit test to use Z3_mk_type_variable for polymorphic datatypes
- Test creates pair datatype with type variables alpha and beta
- Successfully instantiates with concrete types (pair Int Real) and (pair Real Int)
- Verifies accessor types match and equality terms are well-typed
- All tests pass
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Add Z3_mk_polymorphic_datatype API and refactor datatype creation
- Added new API Z3_mk_polymorphic_datatype to z3_api.h
- Renamed static mk_datatype_decl to api_datatype_decl in api_datatype.cpp
- Modified api_datatype_decl to accept explicit type parameters
- Updated all callers to use renamed function
- Added test_polymorphic_datatype_api demonstrating new API usage
- Both tests pass successfully
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Remove type variable collection logic from constructors
Removed the logic for collecting type variables from field sorts based on constructors.
* Update comments on parameter handling in api_datatype.cpp
Clarify usage of parameters in API documentation.
* Fix OCaml build error - use list instead of array for mk_datatype_sort
Changed mk_sort_ref to pass empty list [] instead of empty array [||].
Changed mk_sort_ref_p to pass params list directly instead of converting to array.
Z3native.mk_datatype_sort expects a list, not an array.
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Add polymorphic datatype example to C++ examples
Added polymorphic_datatype_example() demonstrating:
- Creating type variables alpha and beta with Z3_mk_type_variable
- Defining parametric Pair datatype with fields of type alpha and beta
- Instantiating with concrete types (Pair Int Real) and (Pair Real Int)
- Getting constructors and accessors from instantiated datatypes
- Creating constants and expressions using the polymorphic types
- Verifying type correctness with equality (= (first p1) (second p2))

* Add a fast-path to _coerce_exprs. (#7995)
When the inputs are already the same sort, we can skip most of the
coercion logic and just return.
Currently, `_coerce_exprs` is by far the most expensive part of
building up many common Z3 ASTs, so this fast-path is a substantial
speedup for many use-cases.

* Make rcf is_rational and is_rational_function operations handle zero (#8025)
The representation of the zero rcf numeral is nullptr, and the is_rational
and is_rational_function operations are not expecting to be called with
nullptr. But there isn't a way to test for that in the API, other than
checking if Z3_rcf_num_to_string returns "0".
This patch adds a couple conditions so that is_rational and
is_rational_function operations handle zero. Maybe this isn't the desired
change. For instance, the is_zero operation could instead be exposed in the
API and preconditions added to the relevant operations.

The addition of -fomit-frame-pointer was missing a space (which broke

the --gprof flag in configure.
Also, this option is implied by any level of `-O`, so there is no need
to pass it explicitly in most cases. It could be added to debug,
non-profile builds, but I'm not sure that's useful.

- Removed default working directory to allow explicit working-directory per step

- Kept emscripten setup as required for wasm build

* BLD: Add CMake option to build Python bindings without rebuilding libz3 (redux) (#8088)
* Add CMake option to build only Python bindings without rebuilding libz3
Introduce Z3_BUILD_LIBZ3_CORE option (default ON) to control whether libz3 is built.
When set to OFF with Z3_BUILD_PYTHON_BINDINGS=ON, only Python bindings are built
using a pre-installed libz3 library. This is useful for package managers like
conda-forge to avoid rebuilding libz3 for each Python version.
Changes:
- Add Z3_BUILD_LIBZ3_CORE option in src/CMakeLists.txt
- When OFF, find and use pre-installed libz3 as imported target
- Update Python bindings CMakeLists.txt to handle both built and imported libz3
- Add documentation in README-CMake.md with usage examples

* Disable executable and test builds when not building libz3 core

* Fix docs.yml workflow: remove conflicting native build step (#8091)
* Initial plan
* Fix docs.yml workflow to properly build and deploy documentation
- Remove `no-install: true` from setup-emsdk step to properly install emscripten
- Remove `working-directory: src/api/js` from setup-emsdk step (not needed)
- Remove manual emsdk install/activate/source commands from Build wasm step
- Remove redundant native Z3 build step that conflicted with wasm build
- Simplify Generate Documentation step by removing redundant source command
The main issue was that the native Z3 build was creating a Makefile in the build/
directory before the wasm build ran. The wasm build script then saw the Makefile
existed and skipped the emconfigure step, but the native Makefile doesn't have a
libz3.a target, causing the build to fail. Removing the native build allows the
wasm build to properly configure its own build with emscripten.

* CMake: remove needless variable expansion
This removes an incomplete check in cmake git-submodule detection
logic, directly using filepath probing instead. As a direct usecase,
it fixes submodule building for https://github.com/prove-rs/z3.rs.
The code should refrain from using global parameters such as CMAKE_SOURCE_DIR/CMAKE_BINARY_DIR, especially here which is handling the case of Z3 being a submodule. Instead, use project specific variables like Z3_SOURCE_DIR so that people can incorporate z3 build as part of their build-system.
reported by @nbraud reported in #1227.
Previously the CMake build system assumed that the `.git` file must
be a directory. This is not the case when the working directory
is a "git worktree". In this case the `.git` file is just a plain
file that points to a directory within the true `.git` directory.
This commit essentially implements the logic to traverse this extra
level of indirection and removes some assumptions that the `.git`
file is a directory.
Now that all include paths are relative to the `src/` trees (
one in source tree and one in the build tree) we can simplify
what the CMake build does significantly.
While I'm here I also removed some dead code that wasn't doing
anything useful.
to allow a new mode `SERIOUS_ONLY`.
Modes:
`ON` - All warnings are treated as errors (same as before)
`OFF` - Warnings are not treated as errors (same as before)
`SERIOUS_ONLY` - A subset of "serious" warnings are treated as errors.
Upgrade code is included to upgrade old CMake cache's to use the new
type of `WARNINGS_AS_ERRORS`. We should remove it eventually. The
user's previous setting is preserved when doing this.
Very few warnings are treated as errors for now. Developers can
add more later as they see fit.
