14 days	Move system calling code to the end	Aryadev Chavali

14 days	Change vec_append signature to ensure ptr is constant	Aryadev Chavali

2024-12-19	Separate out node type as an enumeration.	Aryadev Chavali

2024-12-19	Refactor obc for new vector based assembler and better config parser	Aryadev Chavali
	Simpler implementation for configuration parsing with default values. Now using new assembler functions.
2024-12-19	Refactor assembler to use vec_t instead of buffer	Aryadev Chavali
	Clearer, precise and no double pointers.
2024-12-19	Introduce and implement vec_t	Aryadev Chavali
	A vec_t is a dynamic array, separate to a buffer. Should make it easier to distinguish purposes using these two data types.
2024-12-19	Delete buffer stretchy functions	Aryadev Chavali
	A buffer should be a strictly sized array representing a file in memory. No dynamic size functions.
2024-12-19	Fix MAX macro	Aryadev Chavali

2024-12-03	Fix errors with clang	Aryadev Chavali

2024-12-03	Update README	Aryadev Chavali

2024-12-03	Implement compiler (obc)	Aryadev Chavali

2024-12-03	Clean all asm files as well	Aryadev Chavali

2024-12-03	asm_write_{init, exit} when asm_translate_nodes	Aryadev Chavali

2024-12-03	Fix usage and error messages	Aryadev Chavali

2024-12-03	Add better error correcting code for bad loops in parser	Aryadev Chavali

2024-12-03	Fix errors due to no loops	Aryadev Chavali

2024-12-03	Build two executables: obi and obc	Aryadev Chavali
	The names stand for Oreo's Brainfuck Interpreter and Oreo's Brainfuck Compiler, separate tasks that shouldn't be packaged in one executable.
2024-12-03	Wrote an assembler (transpiles brainfuck into assembly code)	Aryadev Chavali
	Provides: + Transpilation from brainfuck code into intel style assembly + functions to assemble and link code
2024-12-03	Simplify main interpreter	Aryadev Chavali
	No need to interpret "multiple files in sequence". Just execute the one file given.
2024-12-03	Capture number of loops in PResult during parsing	Aryadev Chavali

2024-12-03	Moved MEMORY_DEFAULT to lib.h	Aryadev Chavali

2024-12-03	Simplify build system	Aryadev Chavali
	RELEASE and DEBUG builds have differing build flags, triggered by setting RELEASE variable. No longer doing object based compilation because: + gcc is fast enough without it + stale code compilation bugs are annoying + having one output binary to clean-up is just easier when switching build-types
2024-12-03	Implement buffer_t functions to make it stretchy	Aryadev Chavali

2024-12-03	Introduce some nice typedefs in lib.h	Aryadev Chavali

2024-12-03	Add License	Aryadev Chavali

2024-12-03	Added a README	Aryadev Chavali

2024-12-03	Some general reworking, error handling	Aryadev Chavali

2024-12-03	Added some examples to test the interpreter	Aryadev Chavali

2023-09-02	Debug messages	Aryadev Chavali
	Flag which provides some helpful messages for debugging.
2023-09-02	Interpreter COMPLETE!	Aryadev Chavali
	Really easy implementation considering opcodes are super simple. I was right to implement the loop_ref system so at parse time we have resolved references and don't need to do it at runtime (helps with compilation I guess as well).
2023-09-02	New module for parser functions	Aryadev Chavali
	Same principle as main->lib (previous commit).
2023-09-02	New module for functions I no longer need to work on	Aryadev Chavali
	lib.(h\|c) basically has structures and functions I no longer want to stare at in main.c
2023-09-02	Better command line usage	Aryadev Chavali
	Now you can use command line arguments to list a set of input files for the interpreter to use. Currently outputs the data parsed per file.
2023-09-02	Chunk allocator for file handling	Aryadev Chavali
	Apparently you can't just `fseek` because it's "not portable" and "deeply offensive" or whatever, so here's a really dirty chunk based allocator which uses `fread` to just read chunks of data at a time and basically runs around this issue. While it's slower than an fseek solution for general files, this solution allows pipes and other _weird_ things that count as "files" to just werk.
2023-09-02	Better error reporting	Aryadev Chavali
	Using a buffer structure allows me to pass more information to callers and a bit more discretion over how data is passed. Better error reporting via having a file handle and reporting it Emacs/GCC style.
2023-09-02	INIT	Aryadev Chavali
	Simple parser, took like an hour. Not very smart but at least it's like O(n).
