boxedLANG is a lightweight esoteric programming language made by User:Mc20000 in 2026. It was made for education and simple automation.

Language overview

This is still a work in progress. It may be changed in the future.

Commands

Here is how a command is structured:

<name> <vertical bar (|) separated arguments>

For example:

say hi!|0

If a string is passed as an argument, it must be replaced with a tilde (~) like this:

say hello,~world!|0

I/O

• say <message>|<seconds> outputs the message to the console
• ask <message> takes input from the console

Boxes

Boxes are named containers that can store data. They can be managed with these commands:

• box <name>|<data> creates a box
• del <name> deletes a box

They can be referenced to be used as an argument with this syntax:

$<name>

Math

• math <name>|<value1>|<operation>|<value2> performs a math operation on 2 values.

Timing

• wait <milliseconds> waits

Comments

Comments are ignored by the interpreter/compiler. They must start with //.

Examples

Hello, world!

say hello,~world!
ask what~is~your~name
say hello~$name

Truth-machine

box truth|0  //this line is just to catch errors and is not required
ask truth
mark 1
say $truth
jumpif $truth|==|1|1|m  //old "if $truth|==|1|jump|1|m"

Plushie-completeness proof

say 4|0
say 31|0
box var|2
