- The Tcl 7.6 and Tk 4.2 releases
- This page contains information about Tcl 7.6 and Tk4.2,
- which are the most recent
- releases of the Tcl scripting language and the Tk toolk
- it. The first beta versions of these
- releases were released on August 30, 1996. These releas
- es contain only minor changes,
- so we hope to have only a single beta release and to
- go final in early October, 1996.
- What's new
- The most important changes in the releases are summariz
- ed below. See the README
- and changes files in the distributions for more complet
- e information on what has
- changed, including both feature changes and bug fixes.
- There are new options to the file command for
- copying files (file copy),
- deleting files and directories (file delete),
- creating directories (file
- mkdir), and renaming files (file rename).
- The implementation of exec has been improved great
- ly for Windows 95 and
- Windows NT.
- There is a new memory allocator for the Macintosh
- version, which should be
- more efficient than the old one.
- Tk's grid geometry manager has been completely
- rewritten. The layout
- algorithm produces much better layouts than before
- , especially where rows or
- columns were stretchable.
- There are new commands for creating common dialog
- boxes:
- tk_chooseColor, tk_getOpenFile, tk_getSaveFile and
- tk_messageBox. These use native dialog boxes if
- they are available.
- There is a new virtual event mechanism for handlin
- g events in a more portable
- way. See the new command event. It also allows
- events (both physical and
- virtual) to be generated dynamically.
- Tcl 7.6 and Tk 4.2 are backwards-compatible with Tcl
- 7.5 and Tk 4.1 except for
- changes in the C APIs for custom channel drivers. Scrip
- ts written for earlier releases
- should work on these new releases as well.
- Obtaining The Releases
- Binary Releases
- Pre-compiled releases are available for the following
- platforms:
- Windows 3.1, Windows 95, and Windows NT: Fetch
- ftp://ftp.sunlabs.com/pub/tcl/win42b1.exe, then
- execute it. The file is a
- self-extracting executable. It will install the
- Tcl and Tk libraries, the wish and
- tclsh programs, and documentation.
- Macintosh (both 68K and PowerPC): Fetch
- ftp://ftp.sunlabs.com/pub/tcl/mactk4.2b1.sea.hqx.
- The file is in binhex format,
- which is understood by Fetch, StuffIt, and many
- other Mac utilities. The
- unpacked file is a self-installing executable:
- double-click on it and it will create a
- folder containing all that you need to run Tcl
- and Tk.
- UNIX (Solaris 2.* and SunOS, other systems
- soon to follow). Easy to install
- binary packages are now for sale at the Sun Labs
- Tcl/Tk Shop. Check it out!
