wish (Windowing Shell) is a Tcl interpreter extended with Tk commands, [1] available for Unix-like operating systems supporting the X Window System, as well as macOS, Microsoft Windows, [2] [3] and Android. [4] It provides developers the ability to create GUI widgets using the Tk toolkit and the Tcl programming language. [5] [6]
Tk is a platform-independent GUI framework developed for Tcl. From a Tcl shell (tclsh), Tk may be invoked using the command package require Tk. The program wish (WIndowing SHell) provides a way to run a tclsh shell in a graphical window as well as providing Tk. [16] Tk has the following characteristics: Platform-independent: Like Tcl, Tk is ...
rfind(string,substring) returns integer Description Returns the position of the start of the last occurrence of substring in string. If the substring is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.

The Tcl programming language was created in the spring of 1988 by John Ousterhout while he was working at the University of California, Berkeley. [14] [15] Originally "born out of frustration", [11] according to the author, with programmers devising their own languages for extending electronic design automation (EDA) software and, more specifically, the VLSI design tool Magic, which was a ...
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.
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.
The std::string class is the standard representation for a text string since C++98. The class provides some typical string operations like comparison, concatenation, find and replace, and a function for obtaining substrings. An std::string can be constructed from a C-style string, and a C-style string can also be obtained from one. [7]
The erase–remove idiom cannot be used for containers that return const_iterator (e.g.: set) [6] std::remove and/or std::remove_if do not maintain elements that are removed (unlike std::partition, std::stable_partition). Thus, erase–remove can only be used with containers holding elements with full value semantics without incurring resource ...
