  change          transform an s-expression
  flatten         Flatten a list of sexp into its parts. Each part on its own
                  line.
  get             extract parts of an s-expression
  of-xml          convert XML from stdin into an s-expression
  pp              Pretty print S expressions in a human-friendly way.
  print           pretty-print an s-expression
  query           query an s-expression
  resolve-macros  resolve macros in a sexp
  restructure     recover structure of an s-expression
  select          Use CSS-style selectors to traverse sexp trees
  to-csv          converts a list of record s-expressions into CSV format
  validate        validate a sequence of s-expressions on stdin
  version         print version information

Examples

Colorize the output of ocamlc -dlambda:

$ ocamlc -dlambda -c fact.ml 2>&1 | sexp pp -color
(setglobal Fact! (
  letrec
  (fact/1008 (
    function n/1009 (
      if (== n/1009 0) 1 (* n/1009 (apply fact/1008 (- n/1009 1))))))
  (makeblock 0 fact/1008)))

Extract the list of command run by jenga:

$ cat query.sexp
(pipe
  (variant Job_started 1)
  (index 1)
  (wrap (cat (field prog) (pipe (field args) each)))
)
$ sexp query -file query.sexp < .jenga/.jenga.debug
(ocamlc -c foo.mli)
(ocamlc -c foo.ml)
