History: v0.5.0...v0.6.0

🔣 Default Epsilon Configuration

Building on the tools from v0.5 for enabling configurable default epsilons for library functions, add checks to enable confidently generating code without worrying about forgetting to pass an epsilon somewhere, which would previously result in an unsafe generated function. Generating a function without calling symforce.set_epsilon_to_symbol() or symforce.set_epsilon_to_number() will produce a warning, since this allows unintentionally calling functions with singularities with an epsilon of 0. Similarly, setting epsilon to a symbol, but then attemptting to generate a function that doesn't take an argument for epsilon, will yield a descriptive error message. This behavior is also configurable through new additions to the CodegenConfig. The error messages are intended to have thorough explanations, so let us know if they don't make sense by creating an issue!

  • 559e521 Set the default epsilon to a symbol for codegen
  • f17d8b2 Run python tests with ctest
  • 713a00a Add sym.epsilon

➕ Call User-Defined Functions from Generated C++

The code generator supports replacing builtin functions with user-provided alternatives. For instance, a custom my_lib::fast_sin function can be replaced for std::sin. The CppConfig has a new argument override_methods which can be used to specify these functions.

Shoutout to Roy Vorster for contributing this!

  • 7f9cf25 Add function specific overwrites to sympy CPP printer

🏭 More methods on generated types

Add more methods to bring generated Python types up to parity with generated C++ types. In addition, automatically generate some previously handwritten methods.

  • 48f6968 Codegen PoseX.position and rotation
  • 90f14a0 Generate handwritten sym geo methods
  • 81fa502 Uniform position/rotation accessors
  • 1e95863 Generate to_homogenous_matrix for pose types
  • 8e2b19c Codegen ToYawPitchRoll for C++ Rot3

🐍 Generated Python functions are more rigorous about Matrix shapes

PythonConfig supports options for whether generated Python functions should expect all matrix inputs to be 2D arrays, or allow vectors to be 1D arrays. This fixes the previous unintuitive behavior of expecting storage arrays.

  • c163cb6 Reshape matrix inputs to be rank 2
  • 652eb97 Add matrix accessor format function to config and remove matrix_is_1d param

🔧 CI/CD

Add a continuous testing suite on main and on pull requests across compilers and Python versions. In addition, add automatic deployment of the symforce docs to https://symforce.org.

  • ff5a34b Rerun tests with output on failure
  • 716befd Add docs as an artifact of CI runs
  • 6dd9f9a Run CI on push to main and build badge
  • d9633f3 Preserve downloads symforce-org.github.io
  • de296a8 Auto-deploy docs on push to main
  • 20548c3 Add SymForce CI
