Hovatrace is an annotated HTML trace generator for HOVALAAG implemented in Python 3. Over the built-in HTML trace it features
- Original assembler code overlayed with register state trace
- Syntax highlighting
- Jumps not taken are marked
- Constants shown as either (un)signed decimal, hex, or binary
- Tooltips for any constant showing it in all those number bases
- Comments (preceding and same-line) are associated with statements and used to annotate the trace
- Dark/light theme
Hovatrace takes as input a code file and a HOVALAAG-generated trace (usually log.html) and outputs another HTML file. Use --help for full documentation. hovatrace.py can also be imported as a module providing code parsing/tokenization and trace parsing as an API.
$ head 3.vasm
B=20
C=B,B=2047
A=B
D=A,B=-2048
loop:
; Pre: MAX in B, MIN in D.
A=IN1
$ ./hoval 3 3.vasm -t 1
[...]
$ python hovatrace.py -c 3.vasm -fo output.html
This produces
(The sample shows an intentionally inefficient solution for problem 3 so as to not spoil much)
