The lsq language

The lsq language is a query language made to access and traverse s-expression with ease.

A lsq query is made up of filters separated by the | symbol. The list of

While the number of builtin filters and builtin functions provided by lsp is low at the moment, it is rapidly expanding. If the language doesn't support something you need, feel free to open an Issue!

Examples

You have a people.scm file:

((name "Mathis" info (age 20))
 (name "Jean" info (age 28))
 (name "Alice" info (age 12))
 (name "Enric" info (age 20))
 (name "Claudia" info (age 18))
 (name "Amelie" info (age 21))
 (name "Matteo" info (age 16)))

and you want to get the name of everyone who is major (18+). You could write this query:

cat people.scm | lsq ';() | select >=? ;(;info;age) 18'

Outputs:

(name "Mathis" info (age 20))
(name "Jean" info (age 28))
(name "Enric" info (age 20))
(name "Claudia" info (age 18))
(name "Amelie" info (age 21))
