  • Created a vscode extension and put it on the marketplace! It's called Kathleen Syntax Highlighting.

09-10/04/24

  • Implemented loops
    • Loops are named because that was the easiest way to implement this
  • Implemented incrementing integers

03-04/04/24

  • Now works as CLI tool
    • Accepts parameters
      • arg1: input file
      • arg2: output file
      • arg3: extra
        • noasm: dont assemble using NASM
        • nolink: dont link using GCC
        • keep: keep all intermediate files
  • Updated nar_generator.rs to allow recursively unpacking the IR.
  • Formatted from 4 space tabs to 2 space tabs

02/04/24

  • Removed sex from the compiler

01/04/24

  • Added sex to the compiler

30-13/03/24

  • Added "stdlib.asm", contains function for int -> str and the info in the .data section previously in "external.asm"
    • Printing 64 bit unsigned integers now works
  • Fixed issue with too many newlines or weird characters after every print. print behaves as expected now.

23/03/24

  • Embedded all files into the compiled binary. The program can now access asm/nasm-x64-linux/* even when run outside of the project directory.
  • Added two errors in error.rs and used them in main.rs for handling:
    • Missing command line argument: file path
    • Provided file does not exist

04-16/03/24

  • Constant strings, printing of constant strings and printline finally work.

02-03/02/24

  • Started working on strings in the tokenizer, however current implementation sucks.

  • Currently working on re-doing the variable types.

    • Constant integer
    • Dynamic integer
    • Constant string
    • Dynamic string

  • The plan is:

    • Have constant string printable
    • Have dynamic string printable
    • Have ints printable

01/02/24

  • Made the errors nicer with the colored crate.

29/02/24

  • First compilation! All the first program did was put an integer on the heap.
  • Made the error messages cleaner by adding an extra space where needed to align everything
    • Before: 
      9 | code
10 | code
11 | code
    • Now: 
       9 | code
10 | code
11 | code

27/02/24

  • Created the assembly code blocks and a function in asm_generator.asm that replaces the "<>" in the asm blocks with the proper values.

26/02/24

  • Finally got the bss idea working.
    • Here's how variables are made:
      • allocate area in .bss for pointer
      • call malloc, put the recieved pointer into the memory area pointed to by the .bss pointer.
      • To access the data, double dereference the BSS pointer.

24-25/02/24

  • Turns out the way I wanted to do things is not possible (store pointer to var in section .data, which is immutable, silly me!)
  • Instead I'm working on a different approach, where we have a list of pointers in the bss section.
  • Today, the 25th, I was finally able to write assembly code that puts a value on the heap.

21/02/24

  • Started work on NAR.
  • Finished Let and Print in both IR and NAR

20/02/24

  • Finished Let binding in IR
    • only supports int.
  • Put the IR generating function in another function to make functions, loops and all that pizazz easier later

Before
