Abstract. This TIP proposes altering the [regsub] command so that it can return the substituted string as the result of the command. Rationale. In many of the most common uses of the [regsub] command, the substituted string is used only once in the immediately following command.

Regular expressions are used by many text editors, utilities, and programming languages to search and manipulate text based on patterns. Some of these languages, including Perl, Ruby, Awk, and Tcl, have fully integrated regular expressions into the syntax of the core language itself.

The GOTO ”jumping” instruction is considered harmful in programming for many years now, but still it might be interesting to experiment with. Tcl has no goto command, but it can easily be created. The following code was created in the Tcl chatroom, instigated by the quote: ”A computer is a state machine.

I’ve looked at trim, trimright, string map, and regsub but in all cases I have one of two problems: either I don’t know how to tell them how to use a variable in their parameters or I don’t know how to tell it to replace something with nothing. For example here’s a test script I’ve written to test this issue:

The source code is compiled into bytecode, which is later interpreted by the Tcl interpreter. It was created by John Osterhout in 1988. The language is commonly used for rapid prototyping, scripted applications, GUIs, and testing. The Tcl stands for tool command language, where the source code of a Tcl script consists of commands.

For the record, Tcl is compiled with TCL_THREADS, and the packages I’m interested in using are just sqlite3 (self-described as thread safe) and ITcl (thread safe as well), and possibly a library of my own (better be thread safe). I’m using Tcl 8.4, Thread 2.6.3. thanks, TJ 2.
