inaka/katana-code

This system is an Erlang library designed for static source code analysis and transformation. It provides capabilities to parse Erlang source code while preserving preprocessor directives, convert compiled beam files back into source code, and evaluate expressions. The library ensures compatibility with recent Erlang/OTP releases by supporting syntax features from versions 25 through 29.

The repository has been initialized with a standard Erlang/OTP project structure using rebar3. This includes a new \rebar.config\ file defining the build profile, dependencies (such as \erlfmt\, \rebar3\_hex\, and \rebar3\_ex\_doc\), and tooling configurations for dialyzer, xref, and linting. A \CHANGELOG.md\ file has been added to direct users to the GitHub releases page, and the \README.md\ has been updated with a project description and contact information. Additionally, an \elvis.config\ file has been introduced to enforce code style rules, and the \.gitignore\ has been updated to exclude standard build artifacts.

Introduces the katana\_code library, providing functions to process Erlang code without expanding preprocessor directives. The core \ktn\_code\ module exposes an API to parse source strings or binaries into a structured parse tree (\parse\_tree/1\), convert compiled beam files back to source code (\beam\_to\_string/1\, \beam\_to\_erl/2\), and evaluate expressions (\eval/1\). The underlying \ktn\_dodger\ module implements a custom parser that bypasses the standard Erlang preprocessor, allowing macros and preprocessor directives to be preserved in the syntax tree rather than expanded. A lightweight \ktn\_io\_string\ module supports this by providing an in-memory IO server for reading source content.
