A collection of Varvara programs from an alternate past.

These are the principal utilities that I have running at all times while I work on the computer. They started off as ports of Macintosh System 7 programs, but have since been standardized and optimized to do as little redraw and disk access as possible.

They all support window shade, of course.

Unix systems

To make a rom usable across your unix system like an application, edit ~/.bashrc, and make the location of your Uxn emulator(example: ~/bin) visible by adding the lines:

export PATH=$PATH:$HOME/bin

alias calendar='uxn11 ~/roms/calendar.rom'
alias  notepad='uxn11 ~/roms/notepad.rom'
alias   noodle='uxn11 ~/roms/noodle.rom'
alias   oekaki='uxn11 ~/roms/oekaki.rom'
alias    turye='uxn11 ~/roms/turye.rom'
alias     left='uxn11 ~/roms/left.rom'
alias     nasu='uxn11 ~/roms/nasu.rom'
alias     nebu='uxn11 ~/roms/nebu.rom'
alias     dexe='uxn11 ~/roms/dexe.rom'
alias     cccc='uxn11 ~/roms/cccc.rom'
alias     m291='uxn11 ~/roms/m291.rom'

alias drifblim='uxncli ~/roms/drifblim.rom'
alias drifloon='uxncli ~/roms/drifloon.rom'
alias   uxnfor='uxncli ~/roms/uxnfor.rom'
alias   uxnlin='uxncli ~/roms/uxnlin.rom'
alias       hx='uxncli ~/roms/hx.rom'

After saving, run source ~/.bashrc to apply your changes, and enjoy calling the programs from anywhere, like: 

left src/main.tal

Drifblim is a Uxntal assembler, written in Uxntal.

Drawing by Rekka Bellum

The assembler is written in Uxntal itself, and is designed to help bootstrap the Uxntal ecosystem, it outputs a symbols file and expects the standard Uxntal Notation. Here are the limits of the implementation:

Drifblim is strong enough to lift Pokemon or people but has no control over its flight. This causes it to drift with the wind and end up anywhere.

A note pad.

An original design by Donn Denman for the Macintosh.

A calendar.

Press enter to add or edit an event.

Turye is a font editor.

This font editor was designed specifically for the creation of uf2 format fonts. Turye's main view shows an overview of the font's glyphs, it also includes various tool to edit the pixels and width value of each character. It supports the theme and snarf files.

A calculator.

The CCCC calculator is a 16-bit postfix calculator that uses fractions as primitives. It includes two special operators, the reciprocal operator and the yet unnamed operator that is the mirror of a division, where instead of putting the first whole number over the second, it makes whole numbers of the numerator and denominator.

Basic operations

Stack operations

The calculator plays notes inspired from the Casio VL-80, you can use it to play little tunes.

A music player.

This player was originally created to test an experimental feature of uxn11 that allows Varvara to communicate with other non-uxn programs, but has since become the only music player that I use. It works as a client to mpg123. The project was created in collaboration with d6.

A spreadsheet editor.

Nebu is a graphical spreadsheet editor for the Varvara system, designed to handle csv/tsv files. Math operations are done by specifying a rectangle range of cells, followed by an operator. A range uses the colon character between two cell identifiers. A cell does at most one operation, and the range must precede the cell and may not include itself recursively.

A5:C7*

There are four arithmetic operator + - * /, four logic operator = ! > <, as well as # to get the number of non-empty cells in a range, and " to concatenate strings. If an operator is not specified, it will default to returning the sum.

Launches instantly, and weights less than an empty Excel file.

A hex editor.

Dexe is a graphical hex editor created to inspect and edit binary files, it displays hexadecimal bytes, ascii characters and .icn sprites.

A catclock, uh.

This Uxntal implementation of the catclock was created in collaboration with Rekka Bellum.

Catclock is originally a X10 program by Tony Della Fera, Dave Mankins, Ed Moy, Deanna Hohn and Philip Schneider, crafted for entertainment, in the late 1980's. It was also ported to the Plan 9 operating system by Tom Duff, which is where I first came across the catclock.
