Introduction

FormMail is an HTML form to email gateway that receives the results of an HTML form and sends them to the specified email recipients.

The formular library contains a collection of routines for parsing emails generated by FormMail. The emails can be read either from an SRFI-40 stream, or from a text file in Unix mbox format.

There are two programs included with the library, form2wiki and form2txt. These programs read messages generated by FormMail from a Unix mbox file, and generate a representation of the form data in wiki format or text format.

This egg includes a copy of NMS FormMail Version 3.14c1 that has been modified to 1) include the submitted fields in the confirmation email; 2) use quotation marks to enclose field text that contains newline characters; 3) escape the submitted text in the notification email.

Library procedures

`read-form:: ENVELOPE * STRM -> FORM`

Given SRFI-40 streams that contain an RFC 822 envelope and message, this procedure parses the headers and fields that are found in the message stream, and returns an s-expression of the form:

(form (envelope <envelope-string>) 
      (headers <RFC 822 header alist>) 
      (fields <field alist>))

`mbox->form-stream:: FNAME -> FORM-STREAM`

Given the name of a Unix mbox file, this procedure reads the file and returns an SRFI-40 stream representation of its contents, where each element in the stream is a form s-expression in the format created by the read-form procedure.

`form-stream->tree:: STRM -> TREE`

Given an SRFI-40 stream created by the mbox->form-stream procedure, this procedure returns an ordered dictionary structure, where the key is the email address of the form sender, and the value is the list of all forms submitted by that sender. The API of the tree object follows that of the e.g. treap and rb-tree libraries.

Usage of form2wiki and form2txt

form2wiki [options...]

--flimits=FIELD1:LIMIT1,...: specify a comma-separated list of fields and character limits (default is none )
--fields=FIELD1:FIELD2:...: specify a colon-separated list of fields to process (default is all fields )
--mbox-path=PATH: specify path to input mbox (default: mbox)
--order=N: specify order of form id (default: 3)
--prefix=STRING: specify prefix for wiki page title (default: Form Submission)
--read-alist=FILE: read an alist representation from FILE (mbox-path is ignored)
-h, --help: Print help
