obf - Oreo's BrainFuck Interpreter/Compiler

Age	Commit message (Collapse)	Author
8 days	Change vec_append signature to ensure ptr is constant	Aryadev Chavali

13 days	Separate out node type as an enumeration.	Aryadev Chavali

13 days	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.
13 days	Refactor assembler to use vec_t instead of buffer	Aryadev Chavali
	Clearer, precise and no double pointers.
13 days	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.
13 days	Delete buffer stretchy functions	Aryadev Chavali
	A buffer should be a strictly sized array representing a file in memory. No dynamic size functions.
13 days	Fix MAX macro	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	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).
