Introduction +--------------- + +This is the README file for the Macintosh version of the Tcl +scripting language. The file consists of information specific +to the Macintosh version of Tcl. For more general information +please read the README file in the main Tcl directory. + +2. What's new? +-------------- + +The main new feature is the Tcl compilier. You should certainly +notice the speed improvements. Any problems are probably +generic rather than Mac specific. If you have questions or +comments about the compilier feel free to forward them to the +author of the compilier: Brian Lewis <btlewis@eng.sun.com>. +Several things were fixed/changed since the a1 release so be +sure to check this out. + +The largest incompatible change on the Mac is the removal of the +following commands: "rm", "rmdir", "mkdir", "mv" and "cp". These +commands were never really supported and their functionality is +superceded by the file command. + +I've also added in a new "AppleScript" command. This was contributed +by Jim Ingham who is a new member of the Tcl group. It's very cool. +The command isn't actually in the core - you need to do a "package +require Tclapplescript" to get access to it. This code is officially +unsupported and will change in the next release. However, the core +functionality is there and is stable enough to use. Documentation +can be found in "AppleScript.html" in the mac subdirectory. + +The resource command has also been rewacked. You can now read and +write any Mac resource. Tcl now has the new (and VERY COOL) binary +command that will allow you to pack and unpack the resources into +useful Tcl code. We will eventually provide Tcl libraries for +accessing the most common resources. + +See the main Tcl README for other features new to Tcl 8.0. + +3. Mac specific features +------------------------ + +There are several features or enhancements in Tcl that are unique to +the Macintosh version of Tcl. Here is a list of those features and +pointers to where you can find more information about the feature. + +* The "resource" command allows you manipulate Macintosh resources. + A complete man page is available for this command. + +* The Mac version of the "source" command has an option to source from + a Macintosh resource. Check the man page from the source command + for details. + +* The only command NOT available on the Mac is the exec command. + However, we include a Mac only package called Tclapplescript that + provides access to Mac's AppleScript system. This command is still + under design & construction. Documentatin can be found in the mac + subdirectory in a file called "AppleScript.html". + +* The env variable on the Macintosh works rather differently than on + Windows or UNIX platforms. Check out the tclvars man page for + details. + +* The command "file volumes" returns the available volumes on your + Macintosh. Check out the file command for details. + +* The command "file attributes" has the Mac specific options of + -creator and -type which allow you to query and set the Macintosh + creator and type codes for Mac files. See file man page for details. + +* We have added a template for creating a Background-only Tcl application. + So you can use Tcl as a faceless server process. For more details, see + the file background.doc. + +If you are writing cross platform code but would still like to use +some of these Mac specific commands, please remember to use the +tcl_platform variable to special case your code. + +4. The Distribution +------------------- + +Macintosh Tcl is distributed in three different forms. This +should make it easier to only download what you need. The +packages are as follows: + +mactk8.0.1.sea.hqx + + This distribution is a "binary" only release. It contains an + installer program that will install a 68k, PowerPC, or Fat + version of the "Tcl Shell" and "Wish" applications. In addition, + it installs the Tcl & Tk libraries in the Extensions folder inside + your System Folder. + +mactcltk-full-8.0.1.sea.hqx + + This release contains the full release of Tcl and Tk for the + Macintosh plus the More Files packages which Macintosh Tcl and Tk + rely on. + +mactcl-source-8.0.1.sea.hqx + + This release contains the complete source for Tcl 8.0. In + addition, Metrowerks CodeWarrior libraries and project files + are included. However, you must already have the More Files + package to compile this code. + +5. Documentation +---------------- + +The "html" subdirectory contains reference documentation in +in the HTML format. You may also find these pages at: + + http://sunscript.sun.com/man/tcl8.0/contents.html + +Other documentation and sample Tcl scripts can be found at +the Tcl ftp site: + + ftp://ftp.neosoft.com/tcl/ + +The internet news group comp.lang.tcl is also a valuable +source of information about Tcl. A mailing list is also +available (see below). + +6. Compiling Tcl +---------------- + +In order to compile Macintosh Tcl you must have the +following items: + + CodeWarrior Pro 1 + Mac Tcl 8.0 (source) + More Files 1.4.3 + +There are two sets of project files included with the package. The ones +we use for the release are for CodeWarrior Pro 1, and are not compatible +with CodeWarrior Gold release 11 and earlier. We have included the files +for earlier versions of CodeWarrior in the folder tcl8.0:mac:CW11 Projects, +but they are unsupported, and a little out of date. + +As of Tcl8.0p2, the code will also build under CW Pro 2. The only +change that needs to be made is that float.mac.c should be replaced by +float.c in the MacTcl MSL project file. + +However, there seems to be a bug in the CFM68K Linker in CW Pro 2, +which renders the CFM68K Version under CW Pro 2 very unstable. I am +working with MetroWerks to resolve this issue. The PPC version is +fine, as is the Traditional 68K Shell. But if you need to use the +CFM68K, then you must stay with CW Pro 1 for now. + +The project files included with the Mac Tcl source should work +fine. The only thing you may need to update are the access paths. +Unfortunantly, it's somewhat common for the project files to become +slightly corrupted. The most common problem is that the "Prefix file" +found in the "C/C++ Preference" panel is incorrect. This should be +set to MW_TclHeaderPPC, MW_TclHeader68K or MW_TclHeaderCFM68K. + +To build the fat version of TclShell, open the project file "TclShells.¼", +select the "TclShell" target, and build. All of the associated binaries will +be built automoatically. There are also targets for building static 68K +and Power PC builds, for building a CFM 68K build, and for building a +shared library Power PC only build. + +Special notes: + +* There is a small bug in More Files 1.4.3. Also you should not use + MoreFiles 1.4.4 - 1.4.6. Look in the file named morefiles.doc for + more details. + +* You may not have the libmoto library which will cause a compile + error. You don't REALLY need it - it can be removed. Look at the + file libmoto.doc for more details. + +* Check out the file bugs.doc for information about known bugs. + +If you have comments or Bug reports send them to: +Jim Ingham +jingham@eng.sun.com + |
