v0.4.0

This is a big release, with big changes to the core of the project which enable some pretty powerful things.

New Features

The main feature for this release is typedef support, together with a huge rework of the type and name extraction algorithm from the parsed C source.

Typedef support

• Make it so that typedef'd names for aggregates are visible to the tool - e.g. stropt "test_t" "typedef struct { char a; } test_t; }" works

  • typedef support for structs
  • typedef support for unions
  • typedef support for enums
    • as aggregates
    • as sub-aggregates/fields

• Support both struct example and example for non typedef types or for pre-typedef defs in typedef types

• Add test cases for everything above

• Add test cases for complex scenarios

  • Array of structs
  • Array with size defined with #define
  • Add test cases for GetAggregateName (before the rest since it's used in current parse tests)

• Use cc.Translate from cznic/cc instead of cc.Parse

  • Finish reworking everything using ast.TranslationUnit for type information
  • Remove old code and make it work with the rest of the pipeline
  • Add docs for parsing rework
  • Add docs to extract.go
  • Refactor stropt.go and add more comments in printing to screen funcs
  • Add docs for enums
  • Make it work somehow without c compiler, since Translate forces a C
    compiler to be there (check examples in cc repo)

Other additions

• Support constant arithmetic expressions in arrays

  • Additive and multiplicative expressions
  • Parentheses expressions
  • Support sizeof expressions
  • Support any combination of the above

• Add a stdint.h hardcoded source file so that users do not have to use a compiler just for width-precise type

  • Using -use-compiler ignores this header file.

• Update go version so the tool includes proper version numbers based on git tag

Fixes and QoL

• Don't print layout for enums, print it with padding only for last one for unions
• Fix union padding algorithm (wrong maximum size/alignment computation)
• When using bare + optimize, don't print aggregates
• Fix a bug where passing more than one width/align flags would only take in the first one and ignore the rest
• Fix a bug where passing an union under analysis prints just one field

v0.3.0

New Features

• the tool now understands and knows hot to handle enums, both for definitions and as fields in aggregates.
• adding a -enum argument to pass the enum size/alignment, defaulting to 4,4.

Fixes and QoL

• fixed a bug where using avr mode activated the optimizer by mistake.

Attached to this release, you can find pre-compiled binaries for v0.3.0 of stropt.

v0.2.0

New Features

• stropt does not need a compiler installed on the machine anymore, if not using include directives
• -32bit mode and -avr mode, which set widths and alignments for base types automatically.
• build facilities

Fixes and QoL

• More test coverace
  Attached to this release, you can find pre-compiled binaries for v0.2.0 of stropt.
