v0.6.0

New release 0.6.0!

v0.5.0

+ Added generation of Mach-O files.

Added

• Generating files with Mach-O format.

v0.4.2

+ Added a new flag to the `disasm` command.

- Fixed a bug in the disassembler.

Added

• New flag --offset for the disassembler command.

Fixed

• Disassembler behavior: it will no longer crash upon encountering the first unknown opcode.

P.S.: Oops, I forgot to change the version to 0.4.2, so the CLI will still show 0.4.1—sorry about that ;(.

v0.4.1

- Fixed a bug with the AST analyzer.

Fixed

• A bug with the AST analyzer; the AST analyzer simply did not check the code.

v0.4.0

+ Added imports.
+ Added analyzer.

Added

• Imports — you can now import functions from kernel32.dll on Windows.
• Analyzer — the analyzer will analyze your code for dead code and errors.

Fixed

• Bug with incorrect Rel32 patching.

v0.3.1

+ Added JMP rel8 and Jcc rel8 (short jumps) to the encoder and decoder.
+ Added missing Jcc mnemonics: JO, JNO, JS, JNS, JP, JNP.
+ The parser now accepts `db`/`dw`/`dd`/`dq` without a leading dot.

Added

• Short jumps — JMP rel8 (0xEB) and all 16 Jcc rel8 (0x70–0x7F) are now supported in the decoder and encoder.
• New mnemonics — jo, jno, js, jns, jp, jnp with aliases (jpe, jpo, jc, jnc, etc.).
• Missing Jcc rel32 — 0x0F 0x80–0x8B for JO, JNO, JS, JNS, JP, JNP (two-byte opcodes).
• Directives without a dot — db, dw, dd, dq work without a leading . (for example, db 0x90 instead of .byte 0x90).

Fixed

• The decoder 0xC7 now correctly accepts the register form (mod=11) for MOV r64, imm32.
• format_memory no longer outputs [rbp + -0x8]; the negative offset shows the - sign.
• decode_memory returns scale: None if there is no index case.
• #[derive(Debug)]added to CodegenOutput and DecodedInstruction.

v0.3.0

+ Added disassembler.

Added

• disasm command in the CLI! You can disassemble .bin files into human-readable code.

---

P.S.: The CLI shows the old version 0.2.1, sorry, I hope this doesn't bother you. If you really need me to rework the release, put a "👀" smiley face, or build rasm.exe from the source.

v0.2.1

+ Reworked the release.yml script.
+ Added a new command to the REPL.

Added

• New ":clear" command in the REPL to clear the terminal.
• Changed the release system; now all releases will be published as archives containing an executable file.

v0.2.0

+ Added RIP-relative addressing support
+ Added REPL mode to the CLI
+ Added binary number support

- Removed old bug in CLI

---

Added

• Added support for RIP-relative addressing! Now you can write:

  lea rsi, [rip + msg]
  mov rax, [rip + val]
  

• Added a REPL mode to the CLI.

• Added support for binary literals (0b...) in the lexer.

---

Fixed

• Bug with the rasm check command in the CLI.

Happy coding!
