# lang (to be renamed) `lang` is a C-like programming language designed for the purpose of learning about compiler construction. Examples can be found in the `examples` folder. ## Usage ``` $ cargo run -- -h Usage: target/debug/lang [options] Options: -h --help print this help menu -t --type TYPE output type (llvm (default), asm, or obj) -o --output FILE output file name ``` Note that the compiler doesn't automatically link object files (yet), so after generating an object file with the `-t` flag, you can link by running `gcc` on the object file. ## Features `lang` supports basic variable assignment, function calls, conditionals, loops, arithmetic, and relational operations. The three main types are `int` (a signed 32-bit integer), `string` (a null terminated string), and `bool`. `lang` also supports calling C functions as long as the necessary types are supported. ### In progress features - Semantic analysis currently reports errors without reporting the location of the error, this will be fixed - Add floating point and unsigned integer types of different widths - Allow function definitions in any order - Scope (currently everything inside a function is in the same scope) - Arrays - For loops (only while loops are supported at the moment) - Allow parenthesis in expressions ### Long term features - Dynamic memory - Optional garbage collections - Algebraic data types and pattern matching
