specter-edn

https://github.com/maitria/specter-edn/

Format-preserving Specter path for EDN and Cloure code.

There is one specter path: SEXPRS. This navigates to a sequence of s-expressions parsed from a string.

For the transform case, specter-edn preserves whitespace and comments using a sort of diffing algorithm to match new S-expression parts to original parts of the parse tree.

Usage

(use 'com.rpl.specter)
(use 'com.rpl.specter.macros)
(use 'specter-edn.core)

(select [SEXPRS FIRST LAST] "[42 26 77]")
;=> 77

(setval [SEXPRS FIRST FIRST] 99 "[42 ; Hi mom!\n6]")
;=> "[99 ; Hi mom!\n6]"

TODO

  • Use clj-format to format new code which isn't matched up with old code.
