package sexp

Release v0.17.0

• [index] expressions in [sexp query] now support negative indexes. -1 selects the last element in a list, -2 selects the second-to-last element, and so on.

• added [sexp pretty] as an alias for [sexp pp]

• [sexp select] now allows selecting on strings with spaces

• The [pp] subcommand can now take a file argument rather than always having to read from stdin.

• Similarly, [sexp validate] can now take one or more filenames as arguments

• Added a subcommand [sort] for sorting a sequence of sexps.

• [sexp to-json] time complexity when merging arrays and objects went from O(n^2) to O(n log n).

• Fixed a [sexp change] bug that was disabling the variable syntax escaping in [rewrite] expressions.

• Added code for a [sexp-group] command for grouping a sequence of sexps by some subexpression. This will eventually become a subcommand of the [sexp] executable. For now it lives in tmp-bin/

• added a -drop flag to [sexp select] and [sexp multi-select] that will output the original sexp with the matching fields removed, rather than printing out the matches themselves.

Release v0.16.0

• added a subcommand [sexp validate] that checks whether an input parses as a sexp

• exposed a new value [Sexp_sort.command]. We are testing this now and it will eventually become the [sexp sort] subcommand.
