Ichiglyph language tools

These are the Ichiglyph language tools. Ichiglyph is a simple Turing-complete language derived from Brainfuck.

Ichiglyph and Brainfuck implement the same set of instructions, the only major difference is their encoding. The following table presents the encoding of the instructions of both languages.

Brainfuck	Ichiglyph
>	ll
<	lI
+	Il
-	II
.	1l
,	1I
[	l1
]	I1

The Ichiglyph language was inspired by a remark by Josefina Mádrová, who cleverly noted that using the characters l, I and 1 in identifiers is a bad practice.

The following tools are available:

• ichiglyph.c: Ichiglyph interpreter
• brainfuck.c: Brainfuck interpreter (as a reference)
• bf2ig.c: Brainfuck to Ichiglyph transpiler
• ig2bf.c: Ichiglyph to Brainfuck transpiler

There are also several Brainfuck and equivalent Ichiglyph sample programs in the examples directory. The original Brainfuck programs were taken directly from pablojorge's GitHub repo. These programs are copyrighted by their respective authors.

What is the use of this?

As with Brainfuck itself and all its variants and derivatives, the purpose is mostly just to have fun. However, Ichiglyph programs could be used to demonstrate that certain fonts are unsuitable for rendering source code.

What does the name mean?

Ichi means one in Japanese. Glyph is an elemental symbol within an agreed set of symbols.
