[ann] [cl-emb-announce] New release CL-EMB 0.2.0

[Stefan Scholl]

New release CL-EMB 0.2.0

CL-EMB is a library to embed Common Lisp and special template
tags into normal text files. Can be used for dynamically
generated HTML pages.


You can download it from
http://common-lisp.net/project/cl-emb/
or install with ASDF-Install.

CL-USER> (require :asdf-install)
CL-USER> (asdf-install:install :cl-emb)


Changes:
- Debugging: CL-EMB:REGISTER-EMB saves the generated lambda form
  when CL-EMB:*DEBUG* is T. You may pretty print this form with
  CL-EMB:PPRINT-EMB-FUNCTION

  CL-USER> (emb:register-emb "test7" " - <% @var foo -escape uri %> - ")
  #<CL-EMB::EMB-FUNCTION {96F1239}>
  CL-USER> (emb:pprint-emb-function "test7")

  (LAMBDA (&OPTIONAL CL-EMB-INTERN::ENV)
    (WITH-OUTPUT-TO-STRING (*STANDARD-OUTPUT*)
      (PROGN
       (WRITE-STRING " - ")
       (FORMAT T "~A" (CL-EMB::ECHO (GETF CL-EMB-INTERN::ENV :FOO) :ESCAPE :URI))
       (WRITE-STRING " - "))))
  ; No value

- New template tag @set can be used to set special variables and
  establish a default for the rest of the code.

  CL-USER> (emb:register-emb "test8" "<% @set escape=xml %>--<% @var hey %>--")
  #<CL-EMB::EMB-FUNCTION {962B839}>
  CL-USER> (emb:register-emb "test9" "--<% @var hey %>--<% @call test8 %>--<% @var hey %>--")
  #<CL-EMB::EMB-FUNCTION {96931A9}>
  CL-USER> (emb:execute-emb "test9" '(:hey "5>2"))
  "--5>2----5>2----5>2--"
