* [cbackend] Adds an AST for C This should cover enough C to implement the microjuvix backend. * [cbackend] Add C serializer using language-c library We may decide to write our own serializer for the C AST but this demonstrates that the C AST is sufficient at least. * [cbackend] Declarations will always be typed * [cbackend] Add CPP support to AST * [cbackend] Rename some names for clarity * [cbackend] Add translation of InductiveDef to C * [cbackend] Add CLI for C backend * [cbackend] Add stdbool.h to file header * [cbackend] Allow Cpp and Verbatim code inline * [cbackend] Add a newline after printing C * [cbackend] Support foreign blocks * [cbackend] Add support for axioms * [cbackend] Remove code examples * [cbackend] wip FunctionDef including Expressions * [parser] Support esacping '}' inside a foreign block * [cbackend] Add support for patterns in functions * [cbackend] Add foreign C support to HelloWorld.mjuvix * hlint fixes * More hlint fixes not picked up by pre-commit * [cbackend] Remove CompileStatement from MonoJuvix * [cbackend] Add support for compile blocks * [cbackend] Move compileInfo extraction to MonoJuvixResult * [minihaskell] Fix compile block support * [chore] Remove ununsed isBackendSupported function * [chore] Remove unused imports * [cbackend] Use a Reader for pattern bindings * [cbackend] Fix compiler warnings * [cbackend] Add support for nested patterns * [cbackend] Use functions to instantiate argument names * [cbackend] Add non-exhaustive pattern error message * [cbackend] Adds test for c to WASM compile and execution * [cbackend] Add links to test dependencies in quickstart * [cbackend] Add test with inductive types and patterns * [cbackend] Fix indentation * [cbackend] Remove ExpressionTyped case https://github.com/heliaxdev/minijuvix/issues/79 * [lexer] Fix lexing of \ inside a foreign block * [cbackend] PR review fixes * [chore] Remove unused import * [cbackend] Rename CJuvix to MiniC * [cbackend] Rename MonoJuvixToC to MonoJuvixToMiniC * [cbackend] Add test for polymorphic function * [cbackend] Add module for string literals
