Detailed Script Descriptions

At the moment this section includes the help sections of each script as it would have been obtained via a > ./[script.py] --help call.

dgasm.py

Usage: dgasm.py [OPTIONS] INPUT_FILE

Command line tool to produce Digirule 2 binaries (.dgb).

The script produces a .dgb file with the same name as the .asm in its input, see option -o to set the output file explicitly.

Options:

-o, –output-file PATH –help Show this message and exit.

dginspect.py

Usage: dginspect.py [OPTIONS] INPUT_FILE

Command line tool to inspect and modify .dgb files.

If modifying the .dgb file, a backup (.bak) with the version prior to applying the modifications is created automatically. To turn this functionality off, see option –no-backup

Options:
-b, --list-binary

Produces a listing of the code in binary as ADDR:VALUE. This format makes keying the program into the Digirule easily by cross referencing the ADDR with the Address LEDs.

-g, --get-mem TEXT

Gets the values of a memory range. The format of TEXT is <Symbol>[:Length[:Offset]]. If only Symbol is provided, it must have been defined in the program for its offset to be automatically determined. In this case, Length will be 1 by default. If Symbol:Length is provided, it must have been defined in the program for its offset to be automatically determined. If Symbol:Length:Offset is provided, Symbol does not have to have beendefined in the ASM program. In this case, Symbol is just a name for a region of memory of Length bytes that starts at Offset.

-s, –set-mem <INTEGER INTEGER>…

Set a memory value (as Address, Value).

-nb, --no-backup

If set then no backup file is created.

--help

dgsim.py

Usage: dgsim.py [OPTIONS] INPUT_FILE

Command line program that produces a trace of a Digirule2 binary on simulated hardware.

Options:
-otf, --output-trace_file PATH

Filename containing trace information in HTML.

-omf, --output-memdump_file PATH

Filename containing final memory space.

-t, --title TEXT

An optional title for the produced trace.

-wd, --with-dump

Whether to include a complete dump of memory at every time step.

-I, --interactive-mode

Whether to execute the program in interactive mode.

-ts, --trace-symbol TEXT

Adds a symbol to be traced in every execution step. The format of TEXT is<Symbol>[:Length[:Offset]]. If only Symbol is provided, it must have been defined in the program for its offset to be automatically determined. In this case, Length will be 1 by default. If Symbol:Length is provided, it must have been defined in the program for its offset to be automatically determined. If Symbol:Length:Offset is provided, Symbol does not have to have beendefined in the ASM program. In this case, Symbol is just a name for a region of memory of Length bytes that starts at Offset.

-mn, --max-n INTEGER

Maximum number of time steps to allow the sim to run for.

--theme TEXT

Specifies the CSS theme to use (e.g. dgbeos)
