I'm now learning Tcl/Tk, but as I'm running Windows, I want to create a fully featured(professional) development environment for this language, but I need to know:
Which tools I need to install(first of all)?
What are the IDEs that support Tcl/Tk development?
What is the best text editor to develop in?
Where I can find some librarys for it(if exists)?
It's possible to do some web applications with it?
It uses CGI?
Start off by installing ActiveTCL. It is free and includes TCL and TK bindings. If you have a favorite text editor you can use that. Make sure you have syntax highlighting. If you want something more advanced, I'd recommend Komodo. It is by active state and has a free version. It semantically understands TCL, so it is more intelligent than a standard text editor. For example it highlights syntax errors while you code.
Now write some code and spread the TCL love!
For an interactive Tcl shell, use TkCon
For an editor, I use Komodo or Vim
For web apps, there are FrameWorks, servers: TclHTTP, Aol Server, Apache modules, and of course CGI
For a text editor I would recommend trying jEdit; it has TCL syntax highlighting. When installed I would also recommend installing the following plugins (which can be done via the built-in plugin manager):
Project Viewer: Allows you to organise your files into projects, which gives it more of an IDE feel.
Editor Scheme: Gives you a set of pre-defined syntax highlighting colour schemes to choose from. My preference is for "zenburn".
As Byron mentioned, ActiveTCL is the place to start when using TCL on Windows. As for a text editor, I personally like SciTE, but any text editor that will do syntax highlighting will do (code folding helps as well).
The TCL wiki has the following page regarding IDEs: http://wiki.tcl.tk/998
If you are in need of a library providing specific functionality, I would first check the TCl wiki. There is no central repository of TCL extensions, but the wiki seems to be the central repository of TCL knowledge.
Yes, you can use TCL for web-based projects. You can find a bit of info here regarding CGI and TCL. Some webservers (AOLServer for instance) have a built-in TCL interpreter.
Others have already mentioned TkCon but most people don't utilise the full power of TkCon. It is much more than a REPL loop (for that you could have just used tclsh or wish). My favourite feature is TkCon's edit command.
Basically:
edit some_file.txt
lets you view and edit files.
set my_variable "some value"
edit my_variable
lets you view and edit the content of a variable, even arrays
proc my_function {} {}
edit my_function
lets you view and edit the body of a proc. In fact, this is how I usually write non-trivial procs in TkCon.
If you're going to write code that needs Windows-specific functionality, you will definitely want to get TWAPI the Tcl Windows API library.
With regards to the mentions of ActiveTcl - ActiveState (the creators of ActiveTcl) have been developing an extension repository. Certainly there are extensions which do not (yet) appear there, but there are over 3000 entities in their repository at this time, so many extensions are present there. ActiveTcl comes with a program called "teacup" which provides a command line interface to the repository, allowing you to install specific extensions (or, if you are like me, allowing you to install all the extensions relevant to your platform).
The Tcler's wiki has a number of references to additional tools and extensions. However, your favorite web search engines are likely to turn up utilities, tools, extensions, and applications not yet documented on the wiki or added to the ActiveState repository.
MyTcl is a fairly nice IDE with a Tcl environment included, autocomplete, syntax highlighting, debugging, etc. It has a similar look and feel to Visual Studio. The homepage is in Korean, but it's not too hard to find the download.

I am just starting out in Tcl and am trying to properly configure an editor and interpreter for use. On Tcl's download page it is recommended to use ActiveState's ActiveTcl, but I am learning Tcl for possible production use and want to avoid paying for it.
I tried setting up Eclipse's DLTK to use for learning, but from what I found I need to direct it to the tclsh executable to use it as the interpreter. In Tcl version 8.6.6, I can't find anything that will work. The supposed formats (I'm on Windows) should follow what's seen here, as I've seen this a few examples/tutorials.
As a last resort, I tried following the Windows instructions here to use my MS Visual Studio 2015 work with this, but there is no such vcvars file (what's asked for when reading makefile.vc after downloading Tcl).
I would really like to use Eclipse for this, so I guess my question is as follows: How do you use tclsh as a Tcl interpreter in Tcl 8.6.6?
ActiveTcl isn't a pay-for product. (ActiveState have some of those, but their language distribution isn't one of them as long as you're not after a support plan.)
To configure Eclipse to use the right installed version of Tcl, go to the Tcl → Interpreters page in the main Preferences panel. That lets you Add… an interpreter, which essentially just requires you to find where the tclsh you want to use is on your filesystem, and to give it a name. I use names like “Tcl 8.6” in my installation, so it isn't exactly rocket science. The DLTK system can find out pretty much everything else once it knows where the interpreter implementation is, but if you have several set up (e.g., I have both 8.5 and 8.6) then you'll need to say which one is default using the checkboxes in the list in the Interpreters pane.
(I've verified the above against Eclipse Neon running on OSX, but I don't think it will vary very much with other versions or platforms.)
I recently found out about liclipse and was very excited about its concept (lite eclipse) especially when newly installed Liclipse managed to start up in 5 seconds. But it seems I cannot find how to use it for any of languages listed on the website as it comes only with PyDev perspective and several other Python-related things (e.g. PyDev), but since I am not a Python developer and was looking for nim and Go support I started exploring their documentation but had no success.
So my question is if I should install the plugins for languages I want (e.g. like in standard Eclipse) but that would be odd since Liclipse says it supports those languages out-of-the-box.
I downloaded the latest version of Liclipse from their website and am on Win32 p;latform if it changes anything.
LiClipse has a lightweight editor for those languages (which provides basic syntax highlighting, outline, comment/uncomment and basic code-completion -- i.e.: based on templates), so, if that's enough for you, you should be able to just open the file you want and use the provided editor.
Now, if you require more features for some given language, you can still install another more full-featured plugin to edit it.
Related to the perspective, you should be able to use the Resource Perspective for any language.
I would like to create a terminal based installer/wizard.
Ideally, it'd be like the Ubuntu server installer, or the Arch Linux installer - a ncurses (?) heavy GUI with lots of form and arrow key goodness.
Second best would be a simpler question/answer type thing, similar to the "adduser" command prompting for password, username, etc.
I am Ruby biased, and would prefer a scripting language (not C), but I'm open to anything. It will only run on Ubuntu server, if that helps.
What are my options?
I'm not certain what you're asking. If you're looking for an implementation tool, you could look at urwid, which is a Python-based GUI toolkit library. It lets you write programs using GTK-style widgets and event interfaces for a text-based interface. If you're a decent scripter, it shouldn't be too hard to start from there and write the code to drive an installation process.
InstallJammer can do what you want in the second form. No ncurses interface to speak of though. 0-] It's written in Tcl/Tk, so it meets your scripting requirement though obviously not in your language of choice. We all have our language of choice, I suppose. 0-]
It would be easier to answer if you specified what you're trying to do. If you're installing something, it might make sense to just create a debian package and use install time configuration options available via debhelper.
If bash or shell scripting is okay, I'd suggest looking at package "dialog". Just put "dialog" as pre-depends for your package and you can use dialog features for your deb installer.
Another possibility could be the "pdmenu" package (origin: http://kitenet.net/~joey/code/pdmenu/).
I am considering doing some automation of tasks on my Windows desktop (e.g. sorting through large collections of music/text/photo files, etc...).
Seeing how my main area of developer expertise is Perl on Unix, I'd prefer to stick to Perl for coding the business logic of whatever I need done, just for the sake of development efficiency.
The question is, if I want to slap some GUI on top of the work (ala Perl::Tk on Unix), what are my GUI toolkit options and which one would you recommend using?
Please note that I'd like this question to be a good learning opportunity to other SO users, so I would welcome ANY answers even if they don't necessarily satisfy my own limitations/needs listed below, although notes elaborating on how your solution relates to these considerations would be very welcome.
My considerations are mostly driven by the fact that I want a quickly developed tool for personal use to save myself time on tasks I now do manually.
Main consideration is Perlishness of development - "Easy things should be easy and hard things should be possible" as a Perl slogan goes. Especially the first part :)
Prefer (but not insist) to be as native as possible as far as components used. E.g. rather re-use Windows' file open dialog vs. having some custom Java dialog.
I would prefer to use something that would have a small learning curve (e.g. no need to learn intricacies of OLE/COM), since the goal here is speedy development of tools I need to simplify my life as opposed to developer education which I concentrate on areas more relevant to my day job :).
But I definitely would love to get exposure to something new/cool while doing this, e.g. if some nice Monad based GUI components are suggested I'm definitely curious.
Performance matters (e.g. I may need to display a directory listing with >10000 files), but is not of paramount concern - I am a pretty good GUI designer and developer and can always architect my app and design a GUI to scale well if needed).
I would strongly prefer (though not insist on) a framework that does not force me to compile stuff. e.g. Perl libraries are more preferable to custom Java stuff I need to compile. But if the framework is perfect in all other respects, I'm open to a compiled solution (as long as it doesn't required me to purchase Visual Studio or somesuch - I want to build a Windows GUI front-end for personal use, not invest in becoming a Windows developer).
I'm pretty open and flexible outside of above constraints. Some ActivePerl/Strawberry Perl libraries, MS PowerShell based components - heck, if nothing better shows up I'll just install Apache on my PC and build a web front-end :)
With respect to "perlishness" of the interface, I'd suggest plain old Tk. Unfortunately, it looks quite antiquated and non-win32-ish.
If you want native widgets, I think your best shots are using the native Windows GUI via Win32::GUI or Wx. I have no experience with Win32::GUI, but Wx is quite nice. It does, however, have a rather steep learning curve and the interface isn't very "perlish". The C++ roots show a little bit (for better or worse).
There are a few Tk-replacements that are actually thin wrappers around Tcl/Tk (I think Tcl::Tk and Tkx). They look more modern than Perl/Tk, but I have no hands-on experience with these either. If you're developing for Windows only, have a look at ActivePerl which comes with (I think) Tkx. Their ppm4 package manager is written using it and looks pretty nice!
There are a number of options listed in perlfaq3 and some additional ones that aren't. I'm only familiar with the Tk-based ones.
Perl/Tk has the most "perlish" interface but it hasn't been updated to take advantage of tile (native/themed widget) support in the current version of Tk (and probably never will be). Tkx uses a different bridge to Tk. It allows access to everything in Tk (and it's faster, too) but the syntax is less perlish. Tkx is designed to be a thin wrapper over Tk; you have to consult the Tk documentation for most things and translate for using it from Perl. The Tcl/Tk module uses the same bridge as Tkx but supports a syntax that's mostly the same as Perl/Tk.
Whether or not you need to compile anything depends on which version of Perl you use. If you use Strawberry Perl you'll probably have to compile something no matter what toolkit you choose. ActivePerl distributions have included Tkx since sometime in the 5.8.x cycle and stopped bundling Tk as of 5.10, although it's still available via PPM. Tcl/Tk is available from CPAN but I haven't been able to get it to work with the Tk library that comes bundled with ActivePerl; you may need to install Tcl separately to use it.
Personally, I used to use Perl/Tk but now use Tkx.
While Tk and Qt are also available (more general frameworks originally intended for other languages, on which you can also use Perl), and Tk probably most popular as it's been around longest, Win32::GUI would seem to meet your requirements best. If you like WISIWYG GUI designers, you could use Loft on top of Win32::GUI, but you don't have to if you'd rather do everything programmatically.
Shameless plug - I am in the process of writing a pure Perl GUI toolkit, XUL::Gui that renders its GUI using Firefox. It allows you do anything Firefox can (XUL, HTML, JavaScript, Flash, other web tech). Firefox uses the native look and feel of the OS (or any other theme you want), and is available for most platforms.
use XUL::Gui;
display Window title=>'My Application',
Button( label=>'click me', oncommand=>sub{ shift->label = 'ouch'} );
It's currently under development, but probably stable enough to start working with. The idea is to be as simple and perlish as possible. Nearly all boilerplate is optional, with sensible defaults. For example, the Window tag is only needed because I wanted to title the window.
The module is up on CPAN. I'd encourage anyone to take a look, and send me feature requests or bug reports.
I'd just stick with Tk myself. It runs on Windows and you already know it.
I would choose GTK because because it has a study guide (at the moment I'm using Wx and there's plenty of available source code in Perl using Wx but no actual official documentation .. apart from some articles, so no book ... no official stuff) , if not Qt is an option also , and it has some proper documentation(but I haven't tried it).
Tk has very big problems and I won't use it.
As for your performance problems ... I'm pretty sure no decent application would be concerned if it's displaying 100000 or 10^100 files , since very few fit on your
screen, so you can do some clipping.
If it is just to get a simple GUI on top of your scripts then the easiest path is VB.NET (or C#). That is what I do.
With Visual Studio's designer it is just a matter of designing the form, double click on the button that will that start processing, add code to read off parameters from the GUI elements (e.g. file paths in TextBox'es) and pass the information to the script through environment variables or command line parameters.
Example from one of my applications (used by real users):
Dim inputFolder As String = txtInputDataMGFfolder.Text
Dim outputFile As String = txtOutputMGFfile.Text
Dim ws As WshShellClass = New WshShellClass
Dim objEnviron2 As IWshRuntimeLibrary.IWshEnvironment = _
ws.Environment("PROCESS")
objEnviron2.Item("INDIR") = inputFolder
objEnviron2.Item("OUTFILE") = outputFile
'It may or may not help for this: the user dialogs for selecting
'files may change the current directory and running the Perl
'script or one of the .pm files would fail.
ws.CurrentDirectory = appPath()
ws.Run("%COMSPEC% /K perl -w MultRawPrepare.pl", 1, False)
Note that use of Windows Script Host for this may not be strictly neccessary, but if it
is then this is needed:
'Requires adding reference to project:
' menu Project/Add Reference/COM/Windows Script Host Object Model
' Note: "Windows", not "Microsoft".
'
'Note: the DLL may not be registered;
' D:
' cd \WINNT\system32
' regsvr32 wshom.ocx
Imports IWshRuntimeLibrary 'For WshShellClass.
appPath() is defined as follows (and required "Imports System.Reflection" in the beginning of the VB.NET file):
Public Shared Function appPath() As String
'"[Assembly]" requires System.Reflection
Dim strAppDir As String = _
Path.GetDirectoryName( _
[Assembly].GetExecutingAssembly().GetModules(False)(0).FullyQualifiedName)
Return strAppDir
End Function 'appPath
User selection of files or folders is easy to add, but is helped by HOW-TO instructions and a little bit of boilerplate code.
The Express edition of Visual Studio for VB.NET is free.
what's a good way to scripting or creating programs unders windows?
How about python?
You will need Notepad, and to learn JScript (not Javascript... JScript), VBScript or Batch. Then you can easily create small scripts, somewhat equivalent to bash shell scripts on Linux.
For the first two, you can read the Windows Script Host documentation.
Windows Powershell is becoming the new Windows scripting language. Being a full .NET language, it is inevitably much more powerful that the horrible old batch scripts one used to have to write (and still retains much of the syntactic sugar of scripting/shell languages).
You can do VBScript without the need to install anything.
Open notepad and enter the following text:
MsgBox "Hello"
Save it as filename.vbs
Double click the file you just created, congratulations - you just created and ran a VBScript.
I'd like to plug AutoIt. It's a free download and comes with it's own editor that can be quickly/easily installed anywhere. The language is very rich and comes with a large library of user defined functions. Integrated context-sensitive help with syntax display. There's even a GUI editor. A final plus is that it compiles to .exe so will run on any win2k/xp/vista/2k3/2k8/7 PC.
I always use Python for scripting on Windows.
A vague question usually gets a vague response.
Download a compiler or interpreter and find a tutorial.
With more information we can better point you in the right direction
I would say there are three clever choices here:
Scripting: Use JSCRIPT because much of what you learn about JSCRIPT can be used in Javascript. You can either graduate to Javascript/AJAX in the browser, or Microsoft .HTA apps.
Or, you could use Python because it has standard modules to do just about anything a sysadmin would do plus addons to access Windows .COM objects and WMI. You can then either graduate to Python on a UNIX platform, Jython (which is Python in the JVM) or IronPython which opens up the entire world of .NET for you.
And there is of course, the non-scripting choice which is about creating programs under Windows. If you choose this you probably have an end-game in mind that is beyond scripting, so start with SharpDevelop and IronPython. Then, as you gain confidence, start working with C# still using the same Sharpdevelop toolset. With this choice you can also graduate to UNIX applications using the MONO .NET environment although if you want to do GUI apps on UNIX you will need to use GTK# instead of Windows Forms.
