DerpText
DerpText, not to be confused with similarly named languages, is a language made by User:Fuckerturd. DERP.
Syntax
Commands have one or more parts containing text, all separated by a command ending character. Variables can consist of zero or more characters, but not all are allowed by the syntax of every command. The varN or textN of a command cannot contain the command ending character because it ends the text.
Semantics
There are variables, a text string, and a command string. There is an infinite number of variables, all initially set to the empty string. The text string is set by the user before the program starts and can be empty. The command string is the program and commands are deleted from the beginning of the string as they are processed. The initial and final values of the text string can be used for I/O.
Commands

| &text1& | Places the text text1 into the text string at the end. |
| >text1>text2> | Deletes all text2 before the first occurrence of text1 in the text string. |
| <text1<text2< | Deletes all text2 after the first occurrence of text1 in the text string. |
| @var1@ | Swaps the text string with the variable var1. |
