Query: data query language

The query language is a powerful domain specific, declarative scripting language that can:

• list concrete and abstract objects
• iterate over them
• evaluate complex logical expressions using them
• selecting/unselecting/printing or drc-reporting objects depending on the result of the evaluation.

This chapter describes the query language and its use. The chapter is split up to multiple sub-chapters:

• the query language (documented in pcb-rnd)
• built-in functions
• fields of concrete model objects

A CLI/scripting tutorial in pcb-rnd doc is also available (note: objects and field names differ in pcb-rnd).
