Can you name an important software written in Tcl or Tk?

Important softwares written in Ruby for example include Rails and Homebrew.

Tcl is the embedded language of git. Standard git gui is written in Tcl/Tk. Tcl is also the script language for sqlite.

.gitconfig is in an INI-like format though, which is not anything like Tcl.

Also, does anyone use the "standard" git GUI?

>Tcl is also the script language for sqlite.

OK, thanks.

I never liked other graphical git clients so I switch between CLI and gitk + git gui according to the task at hand.

Only way I know to remove a file from a commit is by using git commit.

I’m also most comfortable with gitk when reviewing branches

git commit -> git gui

		Thanks for that correction. I was quite confused.

One of the big investment banks use TCL/TK, for real-time e-trading. Source my last gig.

The "important software" are normally kept behind NDAs, so you never hear about their uses. TCL was also used on the Mars Rover.

The FPGA software from Xilinx and Altera are scripted with Tcl/Tk.

This. In fact it seems like plenty of hardware-eng tools use Tcl, and looking at all alternatives it's not a bad choice.

With Tcl you get something like a Lisp with a flexible consistent syntax, but less brainy and more pragmatic, and designed to drive other tools.

		My impression many years ago was that it’s really not that bad. I got up and running writing simple programs immediately, and wouldn’t have tried to go outside its capabilities as a simple scripting language.

Thanks for the reply.

Tk has been embedded in python as the GUI toolkit since at least 2.x days. It's used for IDLE, the IDE shipped with Python, and is also used for the turtle module's graphics.

		Tk also works with Ruby. https://tkdocs.com/

I've read many times in the past that a lot of EDA-related software is written in Tcl and Tk.

Electronic Design Automation.

https://en.m.wikipedia.org/wiki/Electronic_design_automation

See:

https://www.tcl-lang.org/about/uses.html

The section about Embedded Development.

CAD is mentioned there too.

		Pasting that section's content here: Because Tcl is a very compact language, and is easily integrated with special hardware, it is a popular choice for embedded development. You'll find Tcl hidden away on many devices, including many networking products from Cisco and others, and set-top boxes including Tivo. Embedding Tcl within other software projects is of course also hugely popular, and has become the dominant control language in some industries, such as in electronic design automation (EDA) and computer-aided design (CAD) applications.
