I'm trying to find a pastie like webservice that do perform some kind of automatic language detection (in term of programming language) and does the syntax coloring accordingly.
Most pastie websites do not have this feature I'd really love to have and use.
Thanks !
Pygments has something close : http://pygments.org/docs/quickstart/#lexer-and-formatter-lookup
>>> from pygments.lexers import guess_lexer, guess_lexer_for_filename
>>> guess_lexer('#!/usr/bin/python\nprint "Hello World!"')
<pygments.lexers.PythonLexer>
Not perfect but quite useful already.
But yeah I share your frustration with paste service, had the same. In my opinion actually the coloration should be done client side.
https://github.com/alexgorbatchev/SyntaxHighlighter
http://code.google.com/p/google-code-prettify/
are pretty nice in that regard.
I've finished to develop my own tool to do that. It's called UU and performs automatic syntax recognition using highlight.js.
http://uu.zoy.org is free and encode locally what you paste in your browser before sending it to the server.
The API is WIP.

I have a question and was hoping that you could maybe help me out. I currently built an API to communicate between Catia (CAD-Application) and my browser so I can create parts/products read and write parameters etc.
One of my problems is that the only way I know to do this is via ActiveX which I really don't wanna do as it forces everyone to use IE11. Since CatiaV5 is a pretty old Software there won't be any elegant way to use it via some sort of Restful api or similar.
Since I've been working with JavaScript for a while now, did apps for phones but have no idea about browser extensions my question was this. Is it possible to write a Chrome Extension that actually uses com dlls and enables me to set up a connection to a piece of software (in this case Catia) and work with it.
NPAPI plug-ins could be the solution for my problem as it looks from the information I found but it's also supposed to also being phased out.
Do you think it's still worth looking into deeper and studying on writing such an NPAPI app or is there maybe a more elegant way you can think of?
Would be happy for some ideas and suggestions. Thanks in advance and
Greetings Chris
In modern browsers the only way to do this would be using native messaging:
Chrome
Firefox
Edge
FireBreath2 has an abstraction for building c++ plugins which supports native messaging, though the docs are still a little sparse.
Zetakey browser support NPAPI.
We provide HTML5 browser embedded system for industrial and enterprise application.

i'm newbie in FTP connection programming in Cocoa. I found 2 library that i can choose for make my app, but i dont know what's the best between these libraries. The libraries are libcurl and chilkat . The problem is what benefit of each library? Did somebody compare it? or maybe can anyone tell me about your experience? Thank you
I don't have any experience with chilkat, but I can tell yout that libcurl is used in a lot of programming languages and is available on a lot of systems. In for example PHP or on a Mac curl is a great tool to use.
So I would advice libcurl if it's available on your platform. You will probably find more information about curl and it has proven itself on many other platforms.
Also interesting if you want to go with curl is curlhandle. It's a cocoa wrapper around the curl library. Probably very handy in your case, but I've no experience with it.
I can tell you that the difference between libcurl and chilkat is like this: (though you probably know by now)
Chilkat is like the chess game you buy at the store and libcurl is like the plastic in liquid form you buy that you can make any chess piece with.
Libcurl is a slightly abstracted sockets-connector and Chilkat handles everything you'd do, up to a certain amount, with that connection. You're either staring at bits or something "made those bits into an email". I'm about to buy Chilkat for some of the libs, I like the features, but at the same time I wish I had time to read the RFC's and play with the other stuff using libcurl. Anywho, hope that answer is worth something to someone.
Because this question is still ranking high on google i give you my experience.
I bought chilkat in 2015 and moved to libcurl later and my own implementation much later. Both are far from perfect. libcurl just shows it's age and some weak designs.
libCurl is an library that tries to implement all URL able protocols even if they are designed as stream protocol like FTP. Do yourself a favour and only use it with HTTP/HTTPS. It just does the transfer part. Which is not enough for handling. You would love to see at least mime and charset routines to use the downloaded files.
Chilkat is a toplevel library that tries to give you as much highlevel access as possible. It uses background threads in script languages where it is not easy to use. The problem is that the API is terrible, very little documented and total failure when you want to write a quality program. For example it returns requests as a string. There is no way for stream processing. Now imagine you download a large GB iso file, you wont be happy. It can return as a file but then you have to specify this at the begin of a request when you don't knwo the download size.
Also the code quality until proven otherwise is bad. There are a few chilkat source code snippets in the wild which you can find via google and they are pure madness. Ok we don't know how this old code has been refactored now. But it leaves a bad taste, remember this is closed source and there is not a single mention about corner cases, which protocol is implemented, which feature of protocols are implemented and so on. You are using a total black box.
Also it does not allow high performance and high value code. I used it to write a web crawler and it was much much slower then libcurl.
I later used the HTTP and SSH compoenents to automate some server/client management scripts and there it shines. You know both sides and can just test if they work together and don't get any surprises. Then it is indeed easy and better then using the broken python or ruby SSH.
But if you ever contact with another unknown server, Chilkat is not your library.
Is it possible to get and parse JSON using objective C, then manipulate it within the cocoa framework for the iphone/pad? I'm specifically looking to do this for a couple of public APIs out there.
See here: how to do json parsing in iphone
Basically, you should look into the TouchJSON library (with CJSONDeserializer and CJSONSerializer).
Used Json-framework on some previous projects, worked really well.
EDIT: I read your post a bit too fast. I've used it on a Mac app before but not targeting the iphone/ipad. I think it should work but have no background to it. Maybe someone else can confirm?
It's not only possible, it's dirt simple if you use one of the many existing open source projects dedicated to this task. I recommend trying yajl-objc, which offers a streaming parser, but json-framework is a good one too. They're very similar.
I'd stay away from TouchJSON, since it gave me trouble a while back with special characters (line breaks) in strings.
However, I'll join the choir recommending json-framework. Since I switched to that from TouchJSON everything's been running smoothly.
Regarding how to integrate the API in your project, they're equally simple to include and use.
As a side note, I'm just now testing out JSONKit, since it's supposed to be much faster than both TouchJSON and json-framework. However, I can't vouch for its stability yet. The reviews of it are good, though.
If you're developing an application that is only iOS 5.0 or later, you can use NSJSONSerialization.
Where can I find the code for creating an online rebol console like the one here ?
http://tryrebol.esperconsultancy.nl/
Update: for the sandbox system on the server, can't Rebol manage it itself with some security wrapper and its security options ?
As for console itself, I don't know Ruby so I don't want to use TryRuby and why would I need it ? Can't I mimic Rebol console itself by "remoting" it somehow ? Why RT or Esper Consultancy can't make an opensource version ? There's no value in keeping it closed source. Rebol needs to prove it's more open than in the past.
In my opinion, you should aim higher with something like the already open-sourced Try Ruby. You'd type in expressions and it would guide you. Their showcase site is at tryruby.org and is fairly slick.
I modified TryRuby to work with Rebol and it wound up looking like this:
But I'm not going to run it on my server because I didn't want to belabor the necessary sandboxing/etc. or protections against someone running an infinite loop. I can give you what I've got so far if you want it.
I started a tutorial script here that no one seemed interested in helping me with, so I wandered off to other tasks:
http://www.rebol.net/wiki/Interactive_tutorial_script
I'm not sure what exactly you want. You mention you want a remote REBOL shell instead of a tutoring setup, but that's what the Try REBOL site is. There are several reasons it's not open source:
It's in heavy development. I'm currently changing the code regularly.
So it's not in a release state. Preparing it for release, documenting and publishing it would take a lot of extra work, as with most projects.
It's written in my CMS that's also in heavy development. Even if the Try REBOL site were open source, it wouldn't run. The CMS is not planned to be open sourced soon.
It's not meant as a generic REBOL remoting tool, but as a one-off demo site. If that site is running, what's the use of more of them?
As others have answered, there are many generic solutions for remoting that you could use. Also, most parts of the Try REBOL site are readily available as open source:
Syllable Server, produced and published by us.
The Cheyenne web server.
The HTML source of the web client can be viewed, including my simple JavaScript command service bus.
Syllable Server is an essential part of the site, as the sandboxing is not done with REBOL facilities (except some extra limits in the R3 backend), but with standard Linux facilities.
A truly air tight (do I mean silica tight?) sandbox is close to impossible with R2.
R3 (still in alpha) is looking a lot more promising. The deep technical discussions in flight right now (see Cure code and AltME/REBOL3 Proposals regarding unwinds and protect and even occasionally mentioning sandboxes should lead to an excellent sandbox capability.
Right now, the big advance R3 has that makes Kaj's tryREBOL possible is R3's secure policy settings which make it possible (with some careful wrapper code) to construct an alpha/demo sandbox.
To answer your precise question("where can I find code...", you could try asking Kaj for his :)
I'm new to StackOverflow. I'm not sure if this is going to end up as a reply to your comment, or as a new answer.
The somewhat common idea that any project can be open sourced and contributed to by others is a naive view. In the case of my Try REBOL site, it makes no sense. It's not just in heavy development; it's written in a CMS that's also in heavy development. Basically noone could contribute to it at this point, because I'm the only one who knows my CMS. Or in any case its newest features, which I develop by developing Try REBOL, and other example sites. So developing Try REBOL means developing the CMS at the same time, and by definition, I'm the only one who can do that.
More generally, my projects are bleeding edge, innovative technology with a strong vision. The vision is mine, and to teach it to others, I have to build it to show how I intended it to work. So there's a catch 22: to enable others to contribute, I have to finish my projects first, because people typically don't understand them until I show them how they work.
There certainly are other projects where mass contribution makes more sense. Still, only the top projects get the contributors. We found that out the hard way. We created Syllable Desktop and Syllable Server with surrounding infrastructure for contributions. These are fairly classic, well understood operating systems that many people could work on in parallel. However, despite years of begging, we get very few contributions.
So, if you feel a burning need to contribute to our projects, please pick one of the many tasks in Syllable to execute. :-)
This question is maybe somehow inspired with Anyone using Python for embedded projects?; so anyone using some Scheme version or Common Lisp (like ECL) for free/oss/commercial projects?
Personally, I used (and still using) TinyScheme for personal projects where some embedded language is needed, mostly due extremely easy embedding (sorry Python lovers, been there and that is quite painful, especially after I learned from TinyScheme how things can be simple).
The most prominent project I remember hearing about is (Gambit) Scheme on the iPhone. It was shut down by the user agreement for a while but I suppose with the new one, this kind of development is allowed again.
I don't see it on the page any more, but I remember a related blog post about interactive development on the iPhone using Scheme. Very exciting.
