Polyglot piranha for Swift is very slow

[eshi13]

How long does it take for execute_piranha to run on a file of 4000 lines. For me it is running from a very long time. Is it possible I am doing something wrong here. Thanks for help.

what language are u using?

[ketkarameya]

since concrete syntax circumvents tree-sitter query compilation, things will be significantly faster.
There is no particular documentation around concrete syntax.

@danieltrt can u please throw in a few sentences around what CS is and some examples in the readme?

[danieltrt]

Sure. There is one small example here but it's not very elaborate: https://uber.github.io/piranha/docs/reference/dsl/rules

@eshi13 note that concrete syntax is very experimental.
Its accurate at what it does, but at this moment it is not very expressive.
