A library for converting a token stream into a data structure for use in web form posts

Project description


A library for converting a token stream into a data structure comprised of sequences, mappings, and scalars, developed primarily for converting HTTP form post data into a richer data structure. It runs on Python 2.6, 2.7, 3.2, and 3.3.

Please see for the documentation.

See for in-development version.


0.5 (2014-09-29)

  • Switch to an iterative parser rather than a recursive parser to avoid DoS attacks.
  • Add the ignore operation. The subsequent data elements in the stream will be ignored until the corresponding __end__ marker. This feature is useful for form elements designed for client-side scripting, such as a “select all” checkbox in the middle of a list of other kinds of fields.
  • Add support for Python 3.3.
  • Drop support for Python 2.5 / Jython.

0.4 (2012-02-14)

  • Peppercorn will no longer run under Python 2.4. 2.5 or better is required.
  • Python 3.2 compatibility.
  • Moved to GitHub.
  • Pylons project docs theme.
  • Added tox configuration.

0.3 (2010-09-02)

  • 0.2 was a brownbag release; a case was not handled where rename operation types may not have children. This release fixes that.

0.2 (2010-09-02)

  • New operation type: rename. rename begins a special mode. The value of the first subsequent data element in the stream will be used within it’s parent sequence or mapping; any remaining data elements until the corresponding __end__ marker are ignored. This is mostly in support of radio buttons. See the rename docs within for more information.

0.1 (2010-03-23)

  • Initial release.
