Unofficial website about Transceternal programming language (mainly written in Japanese, work in progress)

Install Transceternal

Transceternal can be downloaded from author’s GitHub repository https://github.com/Hakerh400/esolangs/.

$ git clone --depth 1 https://github.com/Hakerh400/esolangs/
$ cd esolangs
$ yarn install

To run the interpreter:

(write program into program.txt)
(write initial arguments into input.txt)
$ touch output.txt
$ node transceternal program.txt input.txt output.txt
$ cat output.txt

Language Description

For detailed explanation, see the official website. This section summarizes the language specification.

Transceternal is “graph-rewriting paradigm programming language”. This means all program-related ones including source code, arguments, output are treated unitedly as graph structure.

the overview of the graph is as follows: (work in progress, I should translate into English):

Example

cat command

On the official website, cat program is written as follows:

catacat

An another cat program can be written with 3 bytes:

aba

An approach to shorten transceternal program

This instruction uses cat as an example:

Step 1: Write down all restrictions which should be followed

a node’s 1-pointer should point to B0 (To finish program)
a node’s 1-pointer should point to B1 (To find B1)
a node’s 0-pointer should point to B0 (To find B0)

This can be created with just two nodes.

Step 2: Write down the program

A := Node No.1
B := Node No.2

Step 3: Consider whether last several bytes can be omitted

By omitting tail, the nodes’ pointer points to themselves.

ababa

The 4th byte means that 1-pointer of b is also b, and 5th byte means that 1-pointer of a is also a. These two bytes can be omitted as follows:

aba

This gets 3-byte cat command.
