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 ...
In version control systems, a commit is an operation which sends the latest changes of the source code to the repository, making these changes part of the head revision of the repository. Unlike commits in data management , commits in version control systems are kept in the repository indefinitely.
Tcl (pronounced "tickle" or as an initialism [8]) is a high-level, general-purpose, interpreted, dynamic programming language. It was designed with the goal of being very simple but powerful. [9] Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition. [10]
Data Definition Language (DDL) Data Control Language (DCL) Transaction Control Language (TCL) DCL commands are used for access control and permission management for users in the database. With them we can easily allow or deny some actions for users on the tables or records (row level security). DCL commands are: [2] GRANT
In computer science and data management, a commit is the making of a set of tentative changes permanent, marking the end of a transaction and providing Durability to ACID transactions. A commit is an act of committing.
These programming languages have simple syntax and semantics, so one can learn them quickly and easily. Some lightweight languages (for example Lisp, Forth, and Tcl) are so simple to implement that they have many implementations (dialects). [2]
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 ...
