Convincing Decision Makers to Go With Tcl edit"i'm working on a side project with a friend now, and i said i wanted to use tcl for it (it's a website, built on wub), and my reasoning came down to, 'i'm going to enjoy it more and have more fun' - and that's what it took!"
Priorities editThis section is a list of things that could help increase Tcl's profile
- Get relisted at The Computer Language Benchmarks Game
- Tcl was previously in the game.

Articles Criticising Tcl, and Responses to Them edit[pidors] 2005-01-20: I just saw 10 Things I Hate About tcl show up in http://del.icio.us/tag/tcl. Would it be worthwhile to address his list? (though it is from Oct 2004, so one might consider it a stale part of the blogoverse). :)George Peter Staplin: It seems to me that most of the arguments in that article could be solved by studying Tcl.n.It seems that the author hasn't used programming languages unlike C. To find syntax errors before runtime execution we have tools such as frink. The delayed-evaluation/syntax-checking isn't a problem in most cases for me. I have, however, wanted the ability to fix the problem in a dialog (during the error) and continue execution after the change (like in Smalltalk, and Lisp), but this would require many changes to Tcl. Furthermore, regarding syntax analysis; I've written plenty of buggy programs that pass a C compiler's checks. Depending on a compiler to find bugs in a program can be a futile pursuit.
How to Advocate Tcl editCaj: When I evangelize Tcl, the number one argument I make is its complementary nature: it is excellent at precisely those things you hate to do in C, and writing in both languages together is really easy. Every coder at some point stares resignedly at a source file thinking, "I wish I could just write this part in perl." Tcl is a cure for exactly that writers block.Don't just defend Tcl, promote it!
peterc 2008-08-19: Another practical way to increase the visibility of Tcl is to suggest modern and current Tcl books to your University library for purchase. Most will not only purchase the books, but, will also put them prominently on display in their foyer for the book's first few weeks in the collection.So you get 'em with "eye-share" at the point of entry for a few weeks, then have crisp and modern-looking textbooks available on the shelf for the browsers later on.
LV: There is a directory entry for Tcl and Tk at http://directory.fsf.org/project/tclTk/ - the FSF directory of free software. However, the entry is 3 years old, refers to 8.5 alpha, makes references to the source being maintained on sourceforge, etc. Someone with time to spend advocating Tcl in the public eye might consider tracking down the process of updating that page, updating this note to add that discovery, and then submit an update bringing the information up to date.MG: can't claim to have a lot of time to spend advocating Tcl, but has registered on the FSF site and filed a bug report that the page is out of date, which appears to be the way to get it updated.
Salesmanship editSee also the About Tcl/Tk pages on www.tcl.tk http://www.tcl.tk/about/If you're like most technical people, you're unclear just how management make decisions on what software is used for a project. At times they seem like a black box into which good advice goes and from which bad decisions emerge. The Linux community has put together some good information on how you can sell management on Tcl (of course, they're telling you how to get Linux accepted, but in most cases the ideas and approaches are the same).
- is salesmanship applied to Linux (and, by extension, to Tcl). This is a great site with some really valuable advice.
- The Four Phases of Acceptance
- The Four Phases of Acceptable are: Ignorance (where people don't know better and say things like: "Tcl? That's the Expect language, isn't it?"), Denial (where people will come up with excuses to avoid changing: "There aren't enough programmers for us to adopt this" or "Nobody uses Tcl"), Fear Uncertainty & Doubt (where people know better but spread misinformation about Tcl: "Tcl isn't supported and anyway it's slow"), and finally Acceptance (can be on a number of levels: some places don't publicly acknowledge that they use it, while others will gladly proclaim the fact).
Myths editDoes it frustrate you to have people saying things about Tcl that you know are untrue, but which are hard to refute on the spot? Here's our cheat sheet for Refuting Common Myths About Tcl:
- No Support
- Many companies offer technical support. The Tcl Developer Exchange provides a list of some companies . And, of course, there's the huge user community on Usenet.
- Only Hackers Use It
- Tcl has an impressive list of references--big companies that are using Tcl.
- Only Hackers Maintain It
- Many of the companies that use Tcl have representatives on comp.lang.tcl, the newsgroup for Tcl developers and maintainers.
- Only Suitable For Scripts
- There's no difference between scripts and programs in Tcl, and many large programs have been very successfully written in Tcl. For instance, ... is the software that drives most of the ... on the Internet. It is written entirely in Tcl.
- I Have To Give Away My Tcl Programs
- Programs you write in Tcl are your intellectual property, and you may sell, license, or give them away as you want. Most Tcl programs are distributed in source-code form, but there are source filters and other tools to render your program unreadable by the casual pirate.
- No Development Environment
- There are very nice development environments, such as Tcl Dev Kit (née TclPro) or Komodo. There is also support in many existing editors, such as emacs, vi, and others, which do syntax coloring of Tcl programs. There are also many debuggers from which you are free to choose (See debugging). And you can do revision control on your Tcl code with any revision control system.
- Tk widgets don't look good under Windows
- yes, Tk widgets look fine under Windows.
- Tk widgets look old fashioned under X11
- See: http://freshmeat.net/articles/view/928/ and Good Looking Tk.
Alternate meanings for Tcl edit

Advocacy Stories editGeorge Peter Staplin: (adds) You should also have firmly in your mind why Tcl is better. Blind faith is like no faith at all.EKB A little story: I took this advice, but with unknown results! There was a discussion thread  on Joel on Software titled "Cross-platform GUI dilemma". The poster described his problem as, "I have a low-level back-end thing that is written in C. I have a command-line shell for it that I wrote as a debugging tool. It's working pretty well and I would like to wrap it in a GUI so I can demo it to nontechnical people. I would like to support Windows, Linux, and Mac if possible." This seemed like a no-brainer, but no one had yet recommended Tcl/Tk and far down the thread there was a post, " geez, this all sounds so complex...wx this and Gtk that and , holy cow...You guys discourage development - I must say, it makes me glad to have my Visual Studio - and now I know why I stick to Windows development lol" Yikes! So I added a post at the end, "You can use Tcl/Tk, then wrap it into a Starkit or with Freewrap for a standalone executable. Tcl/Tk is *great* for wrapping a command-line app in a GUI. Info is available at [...link to Tcler's Wiki...]" After that there was a great, thundering silence, and after a longer time the thread was closed and archived. I got the last word, but I don't know that anyone heard...See: http://discuss.joelonsoftware.com/default.asp?design.4.108173.51
Notice the essay on language selection Kevin Walzer mentions.
http://www.businessweek.com/magazine/content/05_05/b3918001_mz001.htmNice article about the success of Linux. It discusses how they have successfully navigated the waters between wild and wooley [RMS] radicalism, and corporate giants like IBM, and how Linux is on a roll that doesn't look to stop anytime soon. - davidwHJG: Many things can be done in Tcl/Tk much easier than in other languages. I think we need a page for a list / showcase of such programs.
LV: A co-worker, after reading a recent Regular Expressions column by Cameron Laird, had this to say:
- ...on the subject of Tcl being "dead"...
- Tcl and Tk are "dead" in the same sense that mitochondria are "dead". They may not be evolutionarily "hot", or competing overtly in the ecosystem, but their disappearance is not something that I lose sleep over.
Think of all the programming languages of the world as a forest. Tcl is a clearing in the middle of the forest where the sun shines, a cool breeze blows, and you can get a breath of fresh air.You might be lost if you've not been to the clearing before, but it's real easy to find your way around. Just don't expect as many things to be laying on the ground waiting to trip you up.Oh, and you can make your own trees. -- (Bryan Oakley on comp.lang.tcl, 2007-07-12)
