- Hi. I've uploaded version 3.6/3.0 of the `jstools' package to alcatel;
- presumably it will find its way to
- <URL:ftp://ftp.aud.alcatel.com/tcl/code/jstools-tk3.6v3.0.tar.gz>
- shortly. The `jstools' package consists of a large number of libraries,
- including libraries for rich-text manipulation and conversion, elaborate
- bindings support (including Emacs, vi, and EDT support), and various
- metawidgets and dialogue panels (such as a file-selection panel).
- It also consists of a set of applications, of which the most important
- are
-
- jbrowser - a configurable directory browser
- jdoc - a hypertext help viewer (a rewrite of jhelp)
- jedit - an extensible multi-mode text editor
- jmore - a multi-window file viewer
-
- There are also some unsupported applications, notably
-
- jpeople - an address-list and email alias manager
- jlaunchpad - a menu of applications and remote hosts,
- similar to SGI's toolchest
-
- What follows is the contents of the file "jstools-tk3.6v3.0.CHANGES"
- from the distribution.
-
- JSTOOLS VERSION 3.6/3.0 CHANGES AND FUTURE DIRECTIONS
-
- Please send bug reports and comments to me, <js@bu.edu>. I am interested
- in comments on the documentation as well as the code itself.
-
- IMPORTANT: This version is not guaranteed to run under Tk 4.0! It's
- been written and tested under Tk 3.6, and seems reasonably stable there.
- As I write, there's a bug in focus handling in Tk 4.0b2 (the second beta
- release of Tk 4) which poses severe problems for these scripts. The
- non-beta release of Tk 4.0 isn't likely to suffer from this problem, but
- the jstools applications and libraries will function a little
- differently from the way they're documented under Tk 4.0.
-
- CHANGES SINCE VERSION 3.6/2.0
-
- The documentation for each application and library (except for jbrowser,
- which I haven't changed much and whose documentation I haven't updated
- at all) describes the major changes to it, but the highlights include:
-
- GENERAL
- * prefixes added to a number of global variables
- (in future versions, all global variables will have prefixes to
- avoid collisions with other people's code. Thanks to Brian West
- for this suggestion.)
-
- LIBRARIES
- * an overhaul of the library organisation, and lots of new ones
- * better support for rich text, including format conversion
- * a wrapper around the text widget (intended to support undo in
- the future)
- * vi and EDT keyboard emulation modes
- * support for the Compose key for generating non-ASCII characters
- * various other bindings improvements
-
- JEDIT
- * support for multiple windows open at once
- (this change, while perhaps not the most visible, is the most
- pervasive in terms of code)
- * much better rich-text support, including copy and paste
- * an optional buttonbar
- * preferences for which menus are displayed
-
- JDOC
- * it's existence (replacing jhelp)
- * Tcl mode
- * rich-text modes, especially jdoc mode
- * a document file is now viewed as a single, scrollable document,
- with section headings, rather than a set of discrete documents.
- * printing and format conversion is supported
- * arbitrary places in a document can be linked to, rather than
- just the beginnings of sections
- * jdoc can follow links to man pages, and if Mosaic is available,
- it can follow http: or ftp: URL's.
-
- FUTURE DIRECTIONS
-
- * jbrowser is due for a major overhaul, making it support multiple
- windows and multiple columns per window.
- * Real, arbitrarily-deep undo in jedit has been on my list for a long
- time, and I haven't forgotten about it. (Really! :-)
- * I'm going to create a "command" library as a layer of abstraction
- for associating commands with menus, buttons, accelerators, and
- strings. The latter will be used for (part of) natural-language
- support, so jstools applications can be multilingual. This should
- also make it easier to support user customisation of menus and
- keyboard accelerators.
- * I want to make a much more flexible preferences mechanism, along
- the lines of that in exmh, so that (for instance) all the applications
- that used jrichtext.tcl could share a set of preferences (say, for
- screen fonts), and so that individual jedit modes could have their
- own preferences (not just _values_ of preferences, but actual preference
- _categories_).
- * I hope to get jpeople and jhotlist ready for official release reasonably
- soon, and perhaps jlaunchpad as well. [Actually, NCSA Mosaic version
- 2.5 seems to have made jhotlist obsolete...]
- * Achim and I have some ideas for redoing the bindings mechanism that
- should make emulation of vi in particular, but emacs and EDT as
- well, much easier and more complete.
