Tools

An illustration for this article

Note that the precise distinctions between a Tool, a Platform, and a Library are debatable, and entries may be categorized somewhat arbitrarily.

Tools for Retrocomputing platforms might be found in the Retrocomputing article instead.

Formats often have tools for processing them, and those are listed along with the format instead of here.

Note that Cat's Eye Technologies also maintains some forks of some tools.

Console::Virtual

Console::Virtual is a simple, lightweight abstraction layer which allows a program to interact with the user through a console, which is emulated on whatever user interface is really available.

Implementation: Console::Virtual (Perl module)

DAM

DAM is a little Javascript library for creating trees of HTML5 elements in the DOM. It supercedes the element-factory module from yoob.js, and Cat's Eye Technologies' newer gewgaws use it instead of yoob.js for creating their control panels. It's rather a lot like hyperscript except more minimal and, of course, awesomer.

Implementation: DAM (Javascript)

DiskSumo is a program to transfer disk images off a Commodore 64 over the RS-232 port via the XMODEM protocol at 300 baud.

ellsync

ellsync is an opinionated poka-yoke for rsync. "Opinionated" because it was designed for a particular use case for rsync (offline backups). "Poka-yoke" because it exposes a restricted interface to rsync, which prevents using it in dangerous ways.

Implementation: ellsync (Python)

Funicular

Funicular is a system that semi-automates the creation of development environments on eclectic architectures. "Semi-automate" means it automates what it can, and provides repeatable instructions for you to follow for what it can't.

"Eclectic architectures" is not terribly-well defined, but it includes retrocomputing and esoteric architectures. Basically, if you've got an emulator for it and install images for it, you might be able to outfit and run a system for it, using Funicular.

It replaces Amiga Gondola. It can handle such OS/emulator combinations as NetBSD under QEMU, FreeDOS under QEMU, AmigaDOS 1.3 on an Amiga 500 under E-UAE, Applesoft BASIC on an Apple II under linapple, and Commodore BASIC 2.0 on a Commodore 64 under VICE.

Implementation: funicular

shelf

shelf is a "package manager" which doesn't actually install any files. Instead, it stores the source trees of sundry packages in a single directory, creates link farms to the interesting files within those trees, and manages your search paths to include those link farms. those trees. The source trees are typically the working directories of local git or Mercurial clones, or they can be source distributions from tarballs. shelf, written in Bourne shell, is a replacement for toolshelf, which was written in Python.

Implementation: shelf.sh

SITU-MON

SITU-MON is a machine language monitor for 6502-based systems, written (by hand!) during RetroChallenge 2015/07 and entered into an emulated Commodore 64 using SITU-PAN.

Implementation: SITU-MON (Commodore 64)

SITU-PAN

SITU-PAN

SITU-PAN is a front-panel switches simulator for the Commodore 64. It displays 8 virtual LEDs and 8 virtual dip switches on the screen. The LEDs display the bit pattern at the current address in memory. Via the keyboard, the switches may be toggled, a new bit pattern written into memory, and the address advanced. In this way, machine code programs may be entered into memory, and then run. SITU-PAN was written during RetroChallenge 2015/07 for the purposes of entering SITU-MON into an emulated C64.

Implementation: frontpanel.bas

T-Rext is a command-line filter that attempts to clean up spaces and punctuation in a text file. Its purpose is so that, when you are writing a text generator, such as a Markov processor, you need not worry too much about its output format; just toss its output through T-Rext when you're done to make it more presentable.

Implementation: t-rext (Python)

This is a static analyzer, written in Scheme, which can check if given Scheme procedures are total (always terminate, on any input) by checking that they are specified primitive-recursively. What's more, it is written almost entirely in a primitive-recursive style, so it can check itself!

Implementation: TPiS (Scheme)
