A compiler and bytecode interpeter for a made up instruction set inspired by what was used in my A level exam questions.
go build github.com/hrfee/schoolasm
./schoolasm run examples/hello.asmmore cool examples in the examples folder.
built with support for a simple black&white canvas with arrowkey input by default. This depends on SDL, and can take a long time to build at first. It can be disabled with go build -tags=nocanvas.
Usage: ./schoolasm [arguments] [run/build/exec] filename
run: compile and execute a program.
build: compile and write to <filename.sch>.
exec: run a compiled binary.
-debug
print extra info when parsing & instruction info as they are executed. Doesn't play well with the table.
-width int
width of canvas window. Disabled if blank.
-height int
height of canvas window. Disabled if blank.
-offset int
starting address of memory used to set pixels for the canvas window. Goes by row, then column.
-scale int
scale pixel size for canvas. (default 10)
-showmem string
comma-separated list of named/decimal addresses to show the value of on each cycle. named addresses only available with run.
-step int
exec/run only. Wait this many milliseconds between each execution cycle.
-table
exec/run only. show table of memory contents during execution. Enabling sets step to 500ms.
Instructions and encoded format are explained in spec.txt.
no license, why would you want to modify/distribute this?
