~ Abstract
This document proposes a division of the Tk toolkit's source code into
functional areas so that each area may be assigned to one or more
maintainers.
~ Background
TCT procedures (see [0]) call for each ''maintainer'' to be
responsible for a portion of the Tk toolkit's source code. Certain
portions of the Tk toolkit's source code are naturally associated with
certain other portions. (For example, the implementation of a command
is intimately related to the documentation for that command.)
Establishing a ''natural'' division of the Tk toolkit's source code
into units needing maintainers is a useful preliminary effort toward a
public call for volunteer maintainers.
~ Rationale
[16] provides a convincing rationale for establishing a simple mapping
from source files to maintainers. It also breaks out maintainers'
functional areas for the Tcl core. This document attempts to develop
a similar mapping for the Tk toolkit.
Just as with [16], this document attempts to divide the Tk toolkit
into a set of the smallest sensible functional units.
One other factor, which was not addressed in [16], is that there is
considerably more platform dependent code in Tk than in Tcl, and it is
unreasonable to expect people to take ownership for pieces of code
that run on platforms they don't have access to. However, we want to
make sure that the maintainer structure supports the cross-platform
nature of Tk.
To that end, in any area where there is both generic code, and
platform specific code, we propose that maintainers can sign up for
the generic code ''and'' code for one or more platforms. By
overlapping the generic code, we ensure that the public interfaces to
Tk will stay consistent among the platforms, while not forcing
maintainers to presume expertise in code they can't even compile, much
less test or understand fully.
~ Proposal
The Tk toolkit shall be divided into the following eighty-six functional
units, each to be assigned one or more maintainers. Each area will also
be a Category in the SourceForge Tracker for Tk:

The following files are shared by all of Tk. Any maintainer may
modify them as necessary to complete changes they are making to
their portion of Tk. Some of the following files define Tk's
API and should be changed only with TCT approval.

~ Platform Dependencies
In addition to the division into functional areas, responsibility for
a given area can also be qualified by one or more ''platform''
specifiers. Some areas, like ''Windows Configuration and Build
Tools'' are obviously platform specific, so the qualification is
unnecessary. Others, like ''Canvas Items'', are wholly generic. But
others, like ''Button'', ''Scale'' or ''Scrollbar'' contain code for
all platforms.
A maintainer can sign up for one of these latter areas, but specify
support for only one platform. This means that that person will be
responsible for the generic code in this area, in conjunction with the
other platform maintainers in this area, and the platform specific
code in that area.
The point behind sharing the generic code among all the maintainers is
so that any changes to the Tk visible face of the widget be designed
in concert for all platforms. Therefore, it is the responsibility of
a platform maintainer for one platform who is sponsering a new feature
for that area to work with the other platform maintainers to ensure
that the feature is implemented on all platforms. One of the
strengths of Tk is its cross-platform nature, and one of the
maintainer's jobs is to ensure that this continues.
Procedurally, the maintainer will be listed as ''Button Widget -
Macintosh'', etc. A maintainer for a given area can sign up for one
or more platforms. Due to the good design of the Tk's platform
dependencies, determining which files are generic, and which are
platform specific is trivial. The generic ones are in the ''generic''
directory, the Mac ones in the ''mac'' directory, etc. Similarly, an
area which has NO files in the mac, win, or unix directories is a
generic area, and no qualifiers are needed.
