Tcl supports multiple programming paradigms, including object-oriented, imperative, functional, and procedural styles. It is commonly used embedded into C applications, [11] for rapid prototyping, scripted applications, GUIs, and testing. [12] Tcl interpreters are available for many operating systems, allowing Tcl code to run on a wide variety ...
incr Tcl from the Ground Up by Chad Smith, published in January 2000. This is a complete reference manual for incr Tcl, covering language fundamentals, OO design issues, overloading, code reuse, multiple inheritance, abstract base classes, and performance issues. Despite its breadth, it follows a tutorial, rather than encyclopedic, approach.
By wrapping part of the pattern in brackets, you can extract it, referencing it with the code %1. Example: The find-replace instruction {{#invoke:string|replace|AaAabc XYZ|^([Aa]*)b?c|%1|plain=false}} gives AaAa XYZ; We can discard the XYZ by putting .* at the end of the search string; this picks up anything after the rest of the pattern.
Tcl allows both quotes (for interpolated strings) and braces (for raw strings), as in "The quick brown fox" or {The quick {brown fox}}; this derives from the single quotations in Unix shells and the use of braces in C for compound statements, since blocks of code is in Tcl syntactically the same thing as string literals – that the delimiters ...
The Tcl programming language has a command called eval, which executes the source code provided as an argument. Tcl represents all source code as strings, with curly braces acting as quotation marks, so that the argument to eval can have the same formatting as any other source code.
Expect is an extension to the Tcl scripting language written by Don Libes. [2] The program automates interactions with programs that expose a text terminal interface. Expect, originally written in 1990 for the Unix platform, has since become available for Microsoft Windows and other systems.
Non-interpolated strings may also escape sequences, in which case they are termed a raw string, though in other cases this is separate, yielding three classes of raw string, non-interpolated (but escaped) string, interpolated (and escaped) string. For example, in Unix shells, single-quoted strings are raw, while double-quoted strings are ...
