GNU cflow TODO list.  2005-11-25
Copyright (C) 2005, Sergey Poznyakoff

* Introduction

This document specifies the roadmap for further modification of
cflow. It is subdivided into four main sections: Planned Status
Overview, and three priority sections: High Priority Issues, Medium
Priority Issues and Low Priority Issues. The entries within each
priority section are placed in order of decreasing priority, the
most urgent ones being the first. 

* Planned Status Overview

The planned utility shall fully conform to POSIX specification of a
cflow utility. 
See http://www.opengroup.org/onlinepubs/009695399/utilities/cflow.html

The package shall have modular architecture: the `cflow' utility itself
shall invoke an external program (a back-end) to perform a lexical analisys
of input sources. This will allow to use `cflow' to analize source files
written in languages other than C.

The output format of the utility shall conform to the POSIX specification.
The program shall also be able to optionally pipe its output to an
external program (a front-end). This will allow for creating reports in
various formats (e.g. graph, html, etc.)

* High Priority Issues

** Divide and conquer: separate main cflow code (/src) and C lexical analizer
(/back-ends/C)

* Medium Priority Issues

** Implement front-end support.

** Provide front ends for: ASCII tree representation (~ current output look),
XML/HTML output.

** Add new back-ends: Yacc, Lex and object files. These are required by POSIX.

* Low Priority Issues

** Add new back-ends: C++, Scheme, Lisp...
