Projects / JTcl


JTcl is an implementation of Tcl (Tool Command Language) written in Java that implements a large extent of Tcl 8.4 syntax and commands, limited only by API restrictions of the Java Virtual Machine. It is based on the Jacl interpreter from the TclJava project.

    Release Notes: A regression bug was fixed in the 'java' package when trying to invoke an unknown method on an object. An encoding may now be specified when sourcing a file containing Unicode characters. The 'file normalize' command does not resolve the last path component if it is a link. The JTcl version is now provided via an information package.

      Release Notes: This is primarily a bugfix and performance release. Reading from stdin now reads as many bytes as possible. Invalid format specifiers now raise an error instead of causing an exception. On-the-fly compilation of Java code for the "hyde" and "TJC" packages now works correctly under Java 7 when using the embedded compiler. Line continuation sequences containing carriage returns and environment variables set for a sub-process now behave as expected.

        Release Notes: Creating a safe interpreter (interp create -safe) now excludes jaclloadjava, jaclloadtjc, and assorted auto_* commands. Java objects created using the Java package are prevented from leaking, which could cause out of memory exceptions in long-running programs. Compiling Tcl code to Java using TJC now uses the -debug compiler flag to include debugging information in the generated class files.

          Release Notes: The "fleet" command has been added to enable simple concurrent programming using message passing between threads. The "dict" command now preserves the order of entries. Eval has been changed to only read spaces and tabs (not newlines or any other whitespace) after a backslash-newline sequence. An exception has been fixed when an empty variable name was accessed.

          •  23 Feb 2012 04:51

            Release Notes: Three new commands have been added: lassign, lrepeat, and lreverse. A new library module was added for manipulating ZIP files. A new command utility builds stand-alone application JAR files. Two bugs that previously caused exceptions while reading from a socket and globbing files were fixed.
