I am working on a Delphi project for the first time, I used to develop on Java.
Is there a way to print in delphi's console like in java.
System.out.println("Message");
which I used to test code and find bugs (primitively).
You must use Writeln (only for console applications).
{$APPTYPE CONSOLE}
begin
Writeln('Hello');
Readln;
end.
If you want to put a string in the IDE's event log, you can use the OutputDebugString function.
I usually use the following code for "debugging" my programs.
showmessage('Hello World');
That's how i do it.. :)
If you want something similar to Java console, you can use CodeSite, which uses an independent viewer
Another similar tool is TraceTool
More logging libraries on this question - Which logging library is better?
For debugging messages there is also the GExperts console to which you can write using the SendXXX procedures in GX_DbugIntf. This unit is part of the GExperts source code which is available on SourceForge.

I am writing/planning to write a program that takes in a java file (or multiple java files), and edits and adds functions/classes/variables and then outputs a new java file (or multiple files).
Is there a C++ or Java library that
Can recognize and output names of classes/functions within a text file
Can recognize and output the names of the input arguments for said classes/functions
Can allow me to insert code at specific lines or within specific functions
Can search for a given variable name/value
Maintains original file formatting
I would prefer not having to manually code something to do the above, so any help would be appreciated.
Thank you in advance!
EDIT: I currently use Eclipse, and am unsure of how to proceed. So to further explain my question:
In eclipse, if I write a program that opens another .java file, How would I go about 'asking' eclipse to output, say, all the class names of the .java file I just opened?
Also I will explain the 'purpose' of this project to further clarify. I want to write a program that can take in any java file, and turn it into a class that can implemented remotely via RMI. To do this I will need to add an execute() function, have the file implement Task and Serializable and add a few variables, etc... Based on my knowledge, doing this in Eclipse would require manual editing of the program, but I would like to completely automate this process.
Thank you, again.
Much of what you need can be found in a modern IDE; and some very good IDEs are open source (eclipse and Intellij IDEA Community Edition for Java). You might look there to see if there are modules that suite your needs.
Looks like you are talking of a tool like eclipse. You might not be looking for a full fledged IDE, but the requirements that you have mentioned are fulfilled by any basic IDE.
If you wish to make one of your own, you can do that using eclipse rich client platform.
All that you would need from Java is the reflection API.
I am currently making a project for school, where I am going to make a program which teaches children how to read. My basic idea for the program was produce the sentence and then get Windows Anna to say it. My question to you is, how can I access Winodws Anna through Java? and is there a better way of doing this?
Thanks
If having the program access internet is acceptable, then you could use iSpeech.
You can use their API, but the problem with that is that it is limited to 200 uses/day.
iSpeech has decently sounding voices, generally more polished than other TTS engines I've tired like espeak or FreeTTS, because it actually pronounces the words more fluently. Sure, it might pronounce 'Wind', relating with air, as 'Wind', relating to twisting, but other than that, it speaks quite well.
Also, while I haven't had any prior experience with this, I found an article that shows you how to access the MS Speech with command line (which can obviously be commanded through Java[if you do not know how, here is a good article]). It is located here. In command line, all you do is type in 'SayDynamic.exe* the text you want to speak".
*Or SayStatic, the other download available on the page.
This method seems to be better in terms of speed and not relying on internet access, but it definitely does NOT pronounce things as well as iSpeech. I guess the ideal thing for your program to have would be to use iSpeech when online, and use the Say*.exe when offline.
The site also provides the source code of the program. As you might notice, it is NOT Microsoft Anna's voice, but you can specify that in the source and recompile it.
Hope I helped!
You can use command line utiity NirCmd that uses text-to-speech API installed on Windows.
So, supply this utility together with your java application and run it with appropriate command line.
You can try FreeTTS : a speech synthesizer written in java.
You can try to call the Microsoft Speech API (SAPI) but I don't know how to do it in java.
Can you tell us how you invoke NirCmd ?
Altenatively to NirCmd, you can build your own tool in C# that will read the text. The text could be within a txt and your tool invoked with the path to that txt as argument. You can easily adapt a demo project like this one : http://www.codeproject.com/Articles/19334/Text-to-Speech-using-Windows-SAPI
There is the Speech platform of Windows

The Speech runtime

You can use JNA (not JNI) to interact with dll from java

Is it possible to call/run a python script file from Java code on the Android platform using SL4A? Basically I have a full blown Java Android app and I have several Python scripts that scrape some information from various web pages. I would like to be able to call these python scripts with the web page and get the results back. Is this possible? If so, can anyone point me in the direction of an example or two?
Thank you,
Harry
run an SL4A script from my application?
http://code.google.com/p/android-scripting/wiki/FAQ#Can_I_run_an_SL4A_script_from_my_application?
Here you go, a solution on how to make Android applications using SL4A and Python. I have developed a functional Python application following this tutorial so I can vouch for it. I assume you can add the Python code and do your data exchange with JSON.
I personally have never tried to mix these two together, though I will probably try after seeing your post.
Also, if you have any problems/questions, related to starting that example, post them here, I might help.
I want to know if it's possible to execute a javascript function from java. Basically I have a javascript function to which I want to pass a string and then get the output from that function.
If it's possible, how do I accomplish it?
EDIT -
I couldn't find a solution to this, what I did was re-write all the javascript code in Java. But I am guessing, Rhino ported on Android should do the trick. If someone has tried it out, please post a solution.
You probably want to take a look at the ScriptEngine. There are plenty of samples out there on how to use it. Works on anything but Mac where they for some reason selected to include AppleScript instead of JavaScript by default.
Edit: Take a look at this page, there seems to be a Rhino port for Android out there.
Javascript is not natively supported in java. If you need it, you may implement the Rhino javascript engine to do this.
"Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically embedded into Java applications to provide scripting to end users."
Hey i was wondering if there is a specific api for printing a bunch of common file types(pdf,doc,docx,txt, etc..). I am trying to develop program similar to HP's eprint. eprint annoys me because it prints an email as well as the file attached to it. I just want something i can send files directly to. I have found that java has a printing api, but that seems to focus on printing something from a gui window. any ideas much appreciated!
Thanks
Morpheous
It would be difficult for Java alone to be able to print a variety of different file types, and most of the time I've seen Java programs use other programs to do the printing by using Runtime.exec. If you're going to be trying to use this though, please be sure to read this extremely important article: When Runtime.exec() won't
