Dan,
I appreciate your feedback, and felt every point you made was valid. See
below for my responses, and after that the text of the latest version of the
proposal.
One change I would make is to put this as the first sentence of the
proposal, instead of at the end of the intro.
Let me know what you think of section one now.
(there is a numbering issue here, this should be 2.4)
Fixed
These two sections, "Language bindings" and "GUI bindings" are a little
confusing (to me). Python is (AFAIK) an optional system component.
Perl too. In fact, before GNOME came around, we didn't have python.
And yet this creates a dependency upon having them.
Very good observation. I had missed this. I have moved language binding to
a future project. (I have decided that we will completely avoid static
language bindings.)
This is a stronger argument, for sure, and a good one. You might want
to start with that. Again, nice work.
Thanks! I changed it as suggested, and thank you again!
Cheers,
-Brian
P.S. - I appreciate everyone's help, and encouragement!!
----------------------------------------------------------------------------------------------------
Changed sections:
---------------------------
1. Broke into two sections, to make more accessible to ARC team members
2.3 Changed to reflect that language binding will be done in a future
project
2.4 Moved some of the arguments against gui to 2.3. Moved precedents to top
of section
2.5 (Numbering only)
2.6 (Slight modification to reflect change in direction for language
bindings
4. Changed the order of the informative links. (I prefer not to use industry
jargon, if I can avoid it. But for you guys that like it: the
"non-normative" links.) :)

Proposal VIM v0.7
1. Introduction and motivation
1.1 Summary
This project proposes to integrate vim version 7.0 (plus any canonical
patches available at the time of integration).
The motivation behind this proposal to bring Vim to the Solaris
operating system is to have such a modern version of vi available on all
Solaris systems. Initially it will coexist with the original vi.
Eventually it is desirable to deprecate vi, and have vim replace vi as
the bundled vi editor. Until such time as this is done, any vim files
that conflict with vi files will not be included in this project. (IE:
ex, view)
1.2 History and context
The vi editor was developed by Bill Joy, one of the founders of Sun. Vi
stands for "Visual Interface", as it was the full screen visual interface
to ex, a line editor that Bill Joy had previously written. At the time
line
editors were popular do the fact that a majority of terminals were line
printer terminals.
For a number of reasons, vi has become one of the most popular non
graphical editors in the history of computing. Vi has not changed much
since it was originally released, it still retains a very small memory
footprint. For this reason, it was included in UNIX SVR4, and has
shipped with every version of Solaris since the company was founded.
Vi was only available on systems that had licensed it from AT&T. This
lead to the development of many vi "clones". These "clones" initially
were developed to bring vi to alternate platforms, in a form that was
as close to the features and functionality of the original vi as
possible.
As time progressed and development continued on these clones, many
of them surpassed the functionality of the original vi. One of these vi
clones, named VIM ("Vi IMproved") was designed from the very beginning
to improve upon the functionality of vi. Today, vim is one of the only
vi "clones" that is still being developed.
Vim is generally considered the most modern and advanced version of vi
available. Because of this it has become the standard version of vi for
most, if not all, major Linux distributions.
2. Discussion
2.1 Functionality
Vim is an advanced, open source, text editor that is based on the
controls
and functionality of vi. Since Bram Moolenaar released vim in 1991, it
has
gone through many revisions. One of the most significant changes, has
been the addition of language aware source code editing features. These
features provide block completion, source highlighting, automatic
indentation, navigation via code blocks and many other programmer
friendly
options.
In addition to the language specific changes, many other features have
been added. These features include an integrated help system, scripting
abilities, file comparison functions, spell checking, undo, redo,
preservation of state between sessions, remote file editing, editing of
compressed files, and editing multiple files simultaneously. These are
just of few of the many improvements vim has made over vi.
2.2 Components
The basic vim functionality is contained within the executable installed
in /usr/bin, 'vim'. Vim will be installed with symbolic links for the
other commands pointing at the main vim binary. Vim is smart enough to
recognize how to behave depending on what command name that was used to
launch it. e.g. - restricted mode, "easy" (modeless) mode, diff mode,
read-only mode, and some combinations of these. It also acts as ex if
called as such, but this project does not propose to deliver this link
until such time as vim can completely replace the System V vi.
There is also a hex dump/undump utility, xxd, and a script to assist a
user in running the built-in vim tutorial.
The complete list of executables and symbolic links is listed in the
exported interface table.
2.3 Language bindings.
At this stage, we are proposing a relatively simple installation of vim.
Although vim can be compiled with support for various extension languages
in addition to the built-in vimscript, we will not be doing so. Because
vi is, and vim will be, the primary basic system text editor, it can not
depend on optional packages, like perl, or python.
In the future we plan to support perl and python, as these languages are
available with OpenSolaris. These language bindings will be built as
individual packages. Once perl and python packages been created, it will
be an ongoing effort to evaluate as additional supported languages are
added to Solaris.
2.4 GUI bindings
Most, if not all, of the major distributions of Linux follow this
convention, and package gvim separately. These gvim packages install gvim
into /usr/X11R6/bin. This has been verified for RedHat Fedora, RHEL, SuSE
Enterprise Linux, Debian, and Ubuntu).
Vim will be configured without GUI support, for the same reason that we
are not including language bindings. Because vi is, and vim will be, the
primary basic system text editor, it can not depend on optional packages,
like X-Windows, or Gnome.
2.5 Documentation
Vim comes with man pages, but the most significant sets of documentation
are accessed via vim itself. Within vim typing ":help" will bring up the
vim help system. Vimtutor is an interactive set of documentation that
uses the vim engine to allow those accessing this instructive tool to
practice what they learn as they learn it.
There are two main sources of additional documentation: SourceForge [1]
and Vim's [2] home pages.
2.6 Future projects
We plan to further enhance the integration of Solaris and vim.
1) Replacing the current version of vi with vim
2) Creating dynamic language binding packages
3) Creating a standalone gvim (GUI vim) package
4) Changing Sun Studio's bundled vim to the system vim
5) Investigate interest in "tiny-vim" or "vim-minimal" package
