Tcl Programming Language with Reference

iOS Universal

A classic Tcl programming language with reference for iPad and iPhone. Programming language is a perfect tool for complex math calculation, study, entertainment and many useful tasks.

The main features:
- compile and run your program;
- online language reference;
- use example programs;
- save/open source code;
- send source code by email;
- work with text input/output;

We will add soon:
- syntax highlighting;
- enhanced source code editor;
- additional symbols keyboard;

Internet connection is required. Look to the screenshots for more information. Thanks for using the application!

========================================

Tcl (originally from "Tool Command Language", but conventionally rendered as "Tcl" rather than "TCL"; pronounced as "tickle" or "tee-see-ell") is a scripting language created by John Ousterhout. Originally "born out of frustration", according to the author, with programmers devising their own languages intended to be embedded into applications, Tcl gained acceptance on its own. It is commonly used for rapid prototyping, scripted applications, GUIs and testing. Tcl is used on embedded systems platforms, both in its full form and in several other small-footprint versions.

The combination of Tcl and the Tk GUI toolkit is referred to as Tcl/Tk.

The Tcl programming language was created in the spring of 1988 by John Ousterhout while working at the University of California, Berkeley.

Tcl interfaces natively with the C language. This is because it was originally written to be a framework for providing a syntactic front-end to commands written in C, and all commands in the language (including things that might otherwise be keywords, such as if or while) are implemented this way. Each command implementation function is passed an array of values that describe the (already substituted) arguments to the command, and is free to interpret those values as it sees fit.

Digital logic simulators often include a Tcl scripting interface for simulating Verilog, VHDL and SystemVerilog hardware languages.

Tools exist (e.g. SWIG, ffidl) to automatically generate the necessary code to connect arbitrary C functions and the Tcl runtime, and Critcl does the reverse, allowing embedding of arbitrary C code inside a Tcl script and compiling it at runtime into a DLL.
