Comma code
A comma code is a type of prefix-free code in which a comma, a particular symbol or sequence of symbols, occurs at the end of a code word and never occurs otherwise.[1]
For example, Fibonacci coding is a comma code in which the comma is 11. 11 and 1011 are valid Fibonacci code words, but 101, 0111, and 11011 are not.
Examples
- Unary coding, in which the comma is
0. - Fibonacci coding, in which the comma is
11.

gollark: <@199585701547868160> I can't seem to go on urn street, did you block me from the claim?
gollark: \` \` \`abcd\` \` \`(remove the spaces)
gollark: Also, you can make nice looking code blocks by putting three backticks at the start and end of your code:```abcd```
gollark: _is horrified at the lack of indentation_
