What is the best way to print - syntax colored and well formatted - code from Pharo/Squeak on paper?
1) Is there a way to print directly from within Pharo/Squeak? (i use it on macosx)
2) Is there a way to export syntax colored, well formatted code from Pharo/Squak?
3) Are there external tools to color and format a filed out piece of code?
For the appendix in my master thesis I used the Pier CMS-to-LaTeX converter in the Pier-Documentation package. However, this plugin only takes class comments and method comments into consideration, it does not print the source code. Pier also provides a package ShoutPier for syntax highlighting of Smalltalk code, so I guess it would require little work to bring the two together. You can find the mentioned extension packages in http://source.lukas-renggli.ch/pieraddons.html.
Pharo browsers seem to use syntax highlighting.
What difficulty are you having reading Smalltalk code using the browsers and senders/implementors ?
Edit: Would something that produces UML give the overview you're looking for? The Dandelion website only shows downloads for old Squeak versions - I don't know if they would work with Pharo.
And perhaps this GSoC project "Generate UML diagrams from Smalltalk code for Pharo" suggests not.
Here's how I did it on my Mac, I think this should work on other platforms too.
Save your categories to a Monticello local folder on your disk -- see the Pharo manual on how to do this: http://book.pharo-project.org/book/PharoTools/Monticello/?_s=hdGOLc_FXsvVY1iR&_k=YYH-Ln8f5mtWZ8z2&_n&148
Browse to this folder, and unzip the .mcz file
You'll see all your code in snapshot/source.st file
You'll need to edit this a bit, to remove the ! characters for e.g., there might be a tool to do this?

There is webdoc project, which allows you navigating code in web browser:
http://ss3.gemstone.com/ss/webdoc.html
(and of course you can print code from your favorite web browser)..
1) Install shout from www.squeaksource.com
2) I don't know. May be you can customize shout.
3) In gnu-smalltalk you have a smalltalk mode for emacs. But I am not pretty sure to understand what you are looking for.
For a school project i need to write or use a online programming editor. It is a part of a bigger project. I thought of a java application, php/html/javascript or flash.
I have a couple of things i could do:
Find a good working application and edit it so it works with the rest of the project
Find good parts for a editor and make it working my self (syntax highlighter, auto-indent, autocompletion, etc.)
Combination of those two
Does anybody know a good editor or have tips for this project or a editor?
Thanks for reading,
Leon
For the syntax highlighting and basic editing part, check out my recent question Textarea that can do syntax highlighting on the fly?
Solutions presented there:
CodeMirror
Bespin (Mozilla only, but great)
For the rest - autocompletion etc. - ... Check out the Wikipedia article Comparison of JavaScript-based source code editors
Interested to see what other suggestions come up.
Bespin comes to mind. Though it might be too bleeding edge, depending on how the rest of the project is built/meant to be used (but hey, programmers love bleeding edge).
If you decide to use PHP/HTML/CSS/JavaScript, see GeSHi for syntax highlighting.
I have a side project developed with ACE.
It connects to your server through SFTP and allows you to create new files,read and edit all from your browser with your file tree at sidebar.
Demo at TePe
Code at Github Repo
I found Cobalah Editor it's also built on CodeMirror but with some customization. There are some themes available we can set, increase or decrease font size.

Improve this question
I am curious about what tools are used to build the next version of themselves.
For example, Delphi has long claimed that "Delphi is written in Delphi".
I assume Visual Studio is written using Visual Studio.
What are some other examples of tools that written in themselves?
Interestingly, the VB.NET & C# compilers themselves are written in unmanaged C++ (leading to the C++ team's T-Shirt: "My compiler compiled yours"). The C# team hopes to have a fully managed-C# hosted C# compiler for VS2010.
Bjarne Stroustrup mentioned in The Design and Evolution of C++ that the first C++ compiler was written in C++.
I've just noticed this is also a question in his FAQ:
The first C++ compiler (Cfront) was
written in C++. To build that, I first
used C to write a "C with
Classes"-to-C preprocessor. "C with
Classes" was a C dialect that became
the immediate ancestor to C++. That
preprocessor translated "C with
Classes" constructs (such as classes
and constructors) into C. It was a
traditional preprocessor that didn't
understand all of the language, left
most of the type checking for the C
compiler to do, and translated
individual constructs without complete
knowledge. I then wrote the first
version of Cfront in "C with Classes".
This is off-topic, but strictly speaking, it is an example of a tool which builds itself.
The reprap - an open-source 3d prototyping machine, which recently gave 'birth' to "its first complete working replicated copy".
I love this kind of stuff.
Generically speaking, C compilers are usually written in C... *nix kernels are compiled on *nix, etc.
Also, there's the pypy project which provides a Python interpreter written in Python.
When gcc (the Gnu C compiler http://gcc.gnu.org/) was not available widely, you had to compile it from source, compiling stage1 compiler, then compile stage2 with stage1, till you have your final compiler. I assume it must be the same today.
Here is another example: Mono's C# compiler is self hosting - i.e. it's written in C# and used to compile itself.
Dog fooding refers to the more general practice of a company using its own product internally, especially during its development.
Lots of folks like to look at how Lisp can be implemented in Lisp.
Squeak is a Smalltalk-80 implementation written in itself.
even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change.
Sun's Java compiler has long been written in Java. However, recent work is writing a JIT compiler in Java as well. This is the JVM component that converts Java byte code to native processor instructions.
We use to develop using RealBasic. The IDE is written in itself, or so I've been lead to believe.
ghc, the Haskell compiler, is mostly written in Haskell.
tcc is another self-hosting C compiler for x86 and ARM. Its claim to fame is being, well, tiny (100k or so for preprocessor, compiler, assembler, and linker).
I would assume that pretty much any tool that's part of the typical development process would be involved in its own development, to whatever extent possible. This includes:
certain programming languages, especially compiled ones
IDEs
text editors
version control systems
bug trackers
build systems
If you're on a team building one of these tools, and you're not developing it for a specific niche that doesn't apply to your team, I don't know why you wouldn't use it to build itself. Having developers be users of the product is one of the best ways to find possible improvements.
For the AmigaOS there was a third party Basic interpreter (don't remember the name) for which you could later buy a compiler. The compiler was delivered as source, so you had to use the interpreter to run the compiler to compile itself...
To cite Kent Beck:
...it may seem a bit like performing brain surgery on yourself.
Visual Studio and Team Foundation Server build themselves. It's called dogfooding, a term which if not originating in Microsoft, it certainly likes
Oracle Application Express is a web application development tool that is built in itself.
Eclipse IDE is generally built and developed using Eclipse IDE.
It is fairly typical to have a languages compiler written in its own language. This is called self-hosting or bootstrapping.
Maven2 is built using Maven2.
Ok, it's not built (i.e. written) using itself, as it is a tool to build (i.e. compile) project, but it is using its own code to compile...
I was amazed with JSLint
In short it has been described as Javascript "compiler" using javascript.
I am building an IDE-based code generator, and I am using it to build itself. If fact, as Stroustrup did, I am first building a valid generator model and using a pre-processor to build the final C++ code to compile. Once I have a good working version of the IDE, I'll start using it to build further versions of itself.
It's like giving a new dimension to the meaning of "recursive programming"!
AFAIK does the OpenJDK build itself first with the installed java and afterwards with itself.
Naturally the Jetbrains team uses its own IDE IntelliJ IDEA to develop this IDE.
I assume this is true for most IDE vendors.
As far as I know, when building EMACS from source, all of the ELISP code is bootstrapped. I found that quite noteworthy.
Not quite what you're asking for, but the entire development environment for Revolution http://www.runrev.com is built using Revolution itself, and the source (except for small parts that enforce the license) is completely exposed in source form. So if you don't like the way the dev environment is implemented, you can change it. Find a bug, fix it. You can also easily build additional development tools and integrate them.
Ada and Forth
I gave the Smalltalk-80 answer an uptick. Best, most elegant example I can think of. The question also reminds me of a slightly related problem that used to be popular: write a program that outputs itself. Not the same level of bootstrapping, but a fun little programming puzzle for your amusement. Maybe not possible in all languages?
The old Watcom C/C++ compiler was built using itself.
Kragen Sitaker's Ur-Scheme is a fine example of a small nontrivial compiler written in itself. That page links to several more good sources in that vein.
I know of etexteditor and vim/emacs.
Are there any other windows editors which have textmate-like snippets support (eg. you write trigger word, press tab, it changes to something, you press tab again, and it changes to first stop, you can then enter something there and it will change on several other places according to snippet defined) ?
I know it's a little weird explanation, but you probably know what I mean.
You can use the snipMate plugin for vim - I use it and it works great
InType could "someday" become what you're looking for, at least the alphas are promising. Sadly, a release version of InType is still far from being ready (see blog and forums).
Update: Currently, I'm using Sublime Text, another great editor: fully Python-scriptable and snippets support.
Redcar, written in Ruby, was just released, but it's not polished by any means.
Apart from that, I don't know of any.
jEdit will do something similar if you use the SuperAbbrevs plugin.
Visual Studio will do this, but it's nowhere near as nice as textmate / e.
I don't use windows but whilst searching for a alternative for linux I came across e-texteditor.
You can look into using an application independent of your IDE, to expand snippets.
I have a lorem ipsum snippet; one that contains my URL, my email, and so on, but you could also make snippets that contain code.
Applications: Textexpander for Mac, Typinator for Mac, Texter for Windows (no experience with the last one, so don't know if it's any good)
Komodo Edit and Komodo IDE both support this, although TextMate is arguably a bit more refined and polished in this area. Komodo Edit is free, however, and compares very favorably against the likes of InType and E for Windows.

Visual Studio 2015 since Update 2 RC
Visual Studio now supports consuming TextMate snippets with
IntelliSense completion by placing tmSnippet files into a snippet
folder.

Another addition to the yo code generator is the option to add
TextMate Snippets (.tmSnippets) to VS Code

I'm not sure if many people know about this text-editor?
jEdit was kinda big in 2004, but now, Notepad++ seems to have taken the lead(on Windows)
Many of the plugins haven't been updated since 2003 and the overal layout and usage is confusing...
I'm sure jEdit has many nifty features, but I'll be damned if I can find out where to find them and how to use them. Reading that manual is a fulltime job on it's own.
I've been using jEdit for a few years now, mainly on windows, but also on Ubuntu.
I use it for: SQL, awk, batch files, html, xml, javascript...
Just about everything except .NET stuff (for which I use Visual Studio).
I love it.
summary
I use jEdit because it has the right balance for me of ease of setting up vs. features and customisability. For me, no other editor strikes quite as good a balance.
cons
It can be a bit hard to make it do the things you want.
pros
I love the plugins
Being able to define my own syntax highlighting etc. is just what I want from a text editor.
The manual is very good and quite readable. I strongly suggest reading it through to get an idea of what jEdit can do for you. (In fact, I suggest this for any software you use)
It's cross-platform. I used it just on windows for a long time, but now I also use Ubuntu, and it works there: I can even copy the configuration files over from my windows machine, and everything works. Nice.
other editors
In the past I did take a look at Notepad++, but that was a while ago, and it didn't have a nice way to define your own syntax highlighting, which is important for me. I also paid for Textmate and UltraEdit at different times (both very good), but in the end, jEdit comes out on top for me.
I also used Eclipse for a year or so. It's fantastic, and it'll do anything you want, but you have to be really into Eclipse to get the most out of it.
I've occasionally wondered about the same thing (what happened to jEdit - though I'm not sure if that was your main question).
Apparently, the main developer, Slava Pestov, left the project in 2006 (to focus on Factor, and his studies), and the jEdit development has never really picked up again after that. Which is a shame. :/ (I haven't actually followed closely, but I guess it's telling that there has not been a major release of jEdit in the last 4 and half years.)
Now, while googling around, I found some info written by Slava himself. It seems at that time he not only gave up jEdit, but developing in Java altogether, after becoming "increasingly frustrated" with the language.
I've been using jEdit since 2003ish. I use it on my Ubuntu 8.04 box at home, however it does have a few bugs: sometimes when you click on a button which opens a dialog, such as "Open File", the dialog will be completely blank.
This could be a Java thing, but it seems a strange issue.
Other than that, I'm quite happy with jEdit - it's the best general editor I've found (so far) for Linux (ducks as hordes of Vi and Emacs users light up their flame cannons)
I like the XML Editor plugin: auto-completion when you close XML (including HTML) tags, plus if you specify a DOCTYPE it gives you auto completion.
There is also a handy plugin for visually viewing diffs between two files.
jEdit is by far, my prefered editor since 2010. It has a unique set of features that I didn't found in any other:
Multi OS: Win, Linux, Mac.
Portable: Just copy a folder and it is ready to use. All settings are kept in .XML and .properties files inside jEdit subfolder. This is crucial if you don't have admin rights on your enterprise workstation.
Search-Replace: The most enhanced I've seen in a text editor: Full Regex specification with Bean Shell scripting capabilities for back references. For instance: Let's say you want to apply an increment on every number found in your text (replace 1 by 2, 10 by 11 and so on). Just search for regex "(\d+)" and replace by a Java expression "Integer.parseInt(_1) + 1". It's just a simple example, but enough to show how powerful it is.
Database: Just select your SQL statement, press a button and get the resultset from MySQL, MsSql, Oracle, Teradata and any other Jdbc compatible RDBMS. Export results to csv. Works like a multi-database command line tool. Browse and navigate on your database schema. (SQL plugin).
Customization: Here is where jEdit shines. There are tons of features. The highlight is the ability to use any java API to expand it! Access them from your Beanshell scripting macros. Example: I needed a function that decode selected text from/to mime64. No problem! I Just downloaded a library from commons.apache.org and accessed it from a jEdit macro. It's just unbeliveable how expandable jEdit can be with this feature.
Highlight: Select a word or phrase and it is highlighted right away in the entire text. The mini-map of ocurrences is shown in the scrollbar. It allows quickly find, for example, a respective css style in separated file just using the mouse. No need for Ctrl+F or type anything. It works even on ordinary txt files. (Highlight Plugin)
Plugins: FTP, XML, Text Diff, Themes, Text Tabs, Highlighter, character map, Mail, Whitespaces, Abbrevs, Minimap...there are hundreds of them.
There are dozens of other nice features that I won't describe here in order to keep this answer not too long. The complete article can be found here and the mime64 example here.
At first glance, jEdit is just another text editor. The full capabilities come into light when you start playing with it's endless customization/expansion power. My initial reluctance of accepting a java-written text editor disappeared when I realize that only a java text-editor could be so extensible. Its initial drawback turned into it's main advantage.
I have been using jEdit for the last five years. And I agree with Mr. Mahan's comment above, jEdit has reached the "just works stage" and does not really need anymore development.
I mainly use it for PHP web development and have tried everything from commercial IDEs (DreamWeaver) to php designer, NetBeans, Eclipse, Apanta and Notepad++. And nothing comes close for customization possibilities. If the plugin does not exist, chances you can whip something together with a BeanShell Macro (assuming you want to dig into Java).
On Windows I use Notepad++ as well, but mainly as a Notepad replacement (I even renamed the notepad.exe)
At the end of the day it comes down to taste. What is important to you and what will make you more productive. A distracting GUI and fluffy features can take you away from what you should be focusing on.
And to boot I have converted a few developers to jEdit along the way.
At the risk of performing necromancy:
Because of the way it's been released the last decade or so, major Linux distributions usually lag quite far behind the latest stable version. The good news is that there are repositories to install and upgrade it automatically on Ubuntu and more.
For a couple years I shared configuration files between Windows, FreeBSD and Linux without problems. That's more than I can say about any other application I've ever used.
The only issue I've heard about is that it used to be slow back in the dawn of time. Now it's really fast.
Encodings and line endings are handled more seamlessly than any other editor except IntelliJ IDEA.
Vertical editing. Just hold down Ctrl and drag to create a rectangular (or even a zero-width vertical) selection.
Better search and replace than any other editor ever except IntelliJ IDEA. I just started writing a list, but it has to be seen to be believed. Just Ctrl-f and see for yourself.
I had to use during my vocational education for XML and XSLT. It had a lot of bugs and didn't work always. I couldn't get to like it, but if I had to test some XSLT I'd give it another shot. I found Notepad++ and I am more than happy with it for what I need.
To your question: Did you take a look at jEdit's plugin list? There are some plugins released 2008 and the latest version was released on 8th August 2008.
Myeah, I just installed the 4.3pre15(latest) and it does look a bit better.
Super feature is the automatic XML DTD creation you can get from one of the plugins.
Now THAT is awsome, especially for big files
After many years, jEdit remains my favorite free validating XML editor. I love the seamless combination of XML validation with plain-text editing features such as regex search-and-replace across multiple files.
I have used jEdit for a number of years, both on PC and Mac (a bit funky on the Mac).
Currently I use it primarily as a folding editor for a number of on-going documentation notes. I have use the folding at the text indent levels - an easy way to collapse and expand file sections, without any work to set up each section.
The feature I really like are the command shortcut alternatives you can set up, the tool bar icon control, and the the abbreviation expansions. The Plugins I especially favor are the BufferTabs to display rows of file/buffer names, and the Whitespace and TextTools.
I recently loaded the GroovyScriptEngine, in part because of the syntax coloring and control for groovy. I set up 2 seperate jEdit versions, in part to maintain seperate history lists, as I update a few dozen files repeatedly.
I loved Notepad++ on windows, but when I made the switch to Mac I was left behind. Since then I have been in tune with utilities that work across multiple platforms so that is why I switched to JEdit over 2 years ago and I have been loving it ever since. It works flawlessly on my Mac, never crashes, is fast, and has many many add-ons. It is based on Java so it works on many different platforms. I think Jedit is equal to or better than Notepad++
My favorite plug-in is the FTP module. I can open, edit and save files on my FTP server just as easily as if they were local.
