I am trying to write a program/script but I am not able to find a coding language (out of many) which would allow me to perform the tasks I want it to do.
I am aware of the fact that there are perhaps numerous coding languages which would allow me to do so, therefore, to make this question a bit more specific: 'Which coding language would you recommend a beginner to write a program which will be able to perform the following tasks (see below)?
Read some variables from a local HTML page
Fill in this variable in a textbox in a running application/program
Click a predetermined button
Loop the above mentioned on some predetermined condition (i.e. whether the variable has changed).
Thanks in advance!
This depends on your programming background, for which platform you are developing application. For windows C# will be good option, java is also another option.

First of all, I want to appreciate the work for the SCIDvsPC Project. I know that the basic SCID one has been discontinued many years back and the developer have done a great job with expanding it and doing his share for the Chess Field. We have a Minor Project to do in this 6th semester of our college. We've decided to start a project on a Chess Next Move Analyzer that is based on variety of filters and implements Self Learning and Machine Learning.
I've been researching over the project idea for the last 2 months. Actually we need to import several games defined on some filters and read and analyze from the PGN file generated. For example, if the user chooses to get the next best move predicted according to the rating range of 2000-2500, our program should only export and analyze the PGN files that have both the opponents from this range only. I know the project can do all this but I'm confused over how to automate this. I mean I have to manually enter the moves and then click on 'Generate PGN' but how to make my program do this ie take input from the user (like first 3 moves), make the project run these moves (what I had to manually) and then generate the PGN file and keep it in a folder.
I've surfed the net about interacting with GUI elements in Windows (we have no problem in working with Linux either) and came to know about Microsoft UI Automation, Python, Java and C# softwares and something like COM. Do the software support COM or any one of these or have you already developed some functionality like this? Please can you guide me over this?
If asked to Generalize this what I want to do is to interact with GUI Elements, be it any application. Take Notepad as an example. Suppose I want to open a file on it, find and replace a particular word. Now, I know how to do this manually but when I have over thousands of file I need some kind of program to do this for me. Do some specific programs like SCID in my case has some feature (read bit about COM) pre-built to handle this? In which programming language domain does this come into? Is using Linux help me more?

Your situation sounds to be quite specific so I doubt whether you will be able to find a pre-existing program to do this for you. Meaning: you'll have to code it yourself.
In which programming language domain does this come into?
Well, this could probably be done in many, many different programming languages. A simple shell script would be able to achieve the Notepad example you gave.
Is using Linux help me more?
No, your goals seem to be pretty achievable by a simple shell script, whether you write it in a Windows, macOS or a Linux distro.
#SB87 gave you some useful hints, I'd like to expand his answers.
Sorry, I don't think you know what you're talking about. Reinforcement learning (better term than self-learning) and machine learning are not something suitable for a college project. It's at the PhD or research level, consider getting yourself into university before even thinking about anything like that.
UI automation is possible, but error prone and slow. If you want to do it, you'd write a console program. You mentioned something about user inputs, do you mean you want to apply machine learning on user mouse-keyboard inputs? It's not going to work. Machine learning for chess requires hundreds and thousands of training set.
I think you should downplay the project and focus on something you can achieve.
Couldn't tell if this was to be in Superuser of Stackoverflow. Here's my guess
Getting straight to the point, what are some programming languages that would be able to simplistically (not golf-standards, necessarily) be able to produce a program that, when run, would provide no UI initially. Though, a UI could be enabled at the press (or more specifically hold) of a button, without the standard minimize;restore-down;close Windows interface?
I have practically just provided my intentions for the program - to be able to produce the above. I understand that as each condition is added a programming language is not necessarily eliminated from the language-pool, however I am curious as for what languages would be able to do this. C++? C#? Java? Python? etc. etc.
I am running Window 7, and am not a 'master' in any language. I have simply played around with, and learned the syntax and simple controls for a small selection of languages.
I want to control the mouse pointer with my application and be able to interact with other programs using my program,
For example I want my application to be able to click on a button on another application
How should I go about solving this problem?
(Any programming language would work, also if you have any suggestion please let me know)
Afterthoughts:
I want to do it in windows operating system and want to test my GUI to see if it works in different scenarios. Any language would work for me since this is not part of the final product but I prefer one of these languages (Python, Java, C# or MATLAB)
Thanks
There are many ways of doing this, and you didn't mention any details of your application (system, target goal, etc...).
If your goal is menial automation, I'd recommend whipping together a quick AutoIt script on Windows. http://www.autoitscript.com/autoit3/index.shtml
If this isn't what you're looking for, please give more details.
Okay, this one is really operating system and windowing specific. But the phrase you're looking for is "mouse grabbing".
As #Mitch suggests, unless you've got a really good reason — like maybe a GUI testing app? — then grabbing the mouse and messing with it in that way is very bad form.
We wish to provide people to be able to add some logic to their accounts(say, given a few arguments, how to compute a particular result). So, essentially, this would be tantamount to writing simple business rules with support for conditionals and expressions. However, the challenge is to provide them a simple online editor where they can create the logic (preferably) by completely visual means (drag/drop Expr-tree nodes maybe -- kinda like Y! pipes).
Does anybody know of a scripting/macro/domain-specific language that lets people do this? The challenge is the visual editor, since we don't wish to invest in developing the UI to do the editing. The basic requirements would be:
1. Embedded into another language, or run securely (no reboot -n or <JUNK-DANGEROUS-COMMAND> >> ~/.bashrc)
2. Easily accessible to users without coding background (no need of any advanced features)
3. Preferably have a simple GUI based editor to create the logic programs accessible to non-developers (kinda like spreadsheets)
4. Some ability to generate compile-time warnings (invalid code) would be good (Type safety?)
5. Ability to embed some data before execution which is available to the interpreter (Eg., name, birthday, amount)
Anybody tried doing something like this and got any ideas? I looked at Lua, Io, Python, Ruby and a host of others, but the challenge essentially is that I don't think non-programmers will be able to understand the code all that much. Something that could be added via "meta-programming" to say a Ruby would be good as well, if an editor could be easily developed!
As a matter fact, Microsoft is developing Oslo, which is right up your alley.
Chris Sells has been writing a lot about it recently.
It is designed to be a way to author DSLs and also to visually author these models with a graphical tool called Quadrant. Sounds very very similar to what you are looking for.
Open source wise, Ruby I think can be close, as you can see if you look at _whytheluckystiff's Try Ruby or Hackety.
I don't think you'll find anything that isn't too generic, especially regarding the GUI editor. There's no generic tools as far as I know that will be able to automatically interface with your program and be able to query data from it and interpret the script into commands in your software -- if there is I'd like to have a copy. Not being flippant, but you will have to do some (probably alot) of work to get this working. It will probably result in you writing a custom DSL.
I would take a look at PowerShell. You could surface all the activities a user would like to script in a very readable way.
There is some talk of using PowerShell to create a DSL on the PowerShell team blog and Bruce Payette, the technical lead, talks about this in his book Windows PowerShell in Action from Manning.
At the other end of the scale is to write something simple as a HyperText Application (HTA) -- assuming Windows of course -- along the lines of my Clive tool. The article on the blog doesn't mention the HTA version, but essentially I could enter VBScript-ish code into one textarea and interpret it on the spot, output going into another text area on the form.
With HTAs giving you all the form control of HTML, plus the DOM, you could come up with something interesting fairly quickly.
I write many scripts at home and on the job. Most of the time the scripts get used only a few times to accomplish their chosen task and then are never used again. However, sometimes I write a script to do something more complicated, something that requires user input. It is at this point that I usually agonize over whether to implement a GUI or stick with a y/n, press 1-10, etc. command-line interface. This type of interface can become tedious to use and difficult to maintain.
I know some things lend themselves to a GUI more than others, such as selecting things in a giant list. However, the time it takes to switch a command-line application to use a GUI is prohibitive. For me, it takes a good amount of time to add a GUI with even the most simple framework I can find.
I am curious if any developers have a method of determining at what point their script has grown enough to need a GUI. Or am I going about this the wrong way, should I always be writing my scripts assuming I might later add a GUI?
This doesn't answer your question but FWIW an intermediate step, between UI and command-line, is to have a configuration file instead of a UI:
Edit the configuration file
Run the program
A configuration file format can, if necessary, be complicated and well-commented.
As with many questions of this type, the answer is that it depends.
If your program/script does just one single thing by receiving a number of inputs from the user, it is better to stick with the non-GUI mode.
If the application is doing more than one thing and if you think that the user will use the application to do a lot of stuff, you may consider using a GUI.
Are you planning to distribute this program to others? Then it is better to provide a GUI.
If the users are non-technical, a GUI is a must!
Thats it.
When you want to hand your stuff over to someone else in a discoverable way. Command-line scripts are awesome because they are simple and elegant, but they are not very discoverable. That is, if you were to hand your scripts over to someone else with no documentation, would they be able to figure out what they are and how to use them? If your tasks are so simple that myscript /? will explain what you need to do fully, then you don't need a GUI.
If on the other hand, you are handing your scripts over to someone who isn't so technical, or needs some more visual guidance about the task to be done, than by all means, a GUI is a good way to go. You might even want to keep your scripts as they are and just create a separate GUI that runs them for maximum flexibility.
I think this decission also depends on the audience who will be using your script: If it is people who are comfortable working with the command line, then there is not pressing need to add a GUI as long as your script has a good /help which explains all the parameters it accepts. But if you want the "average user" to be able to use your program, I'd rather add a GUI because otherwise your program might not be intuitive enough for that user group.
If you only need some "Dialogs" to improve your scripts, you can use KDE Kdialog or Gnome Zenity.
I can't count the number of times I've written what I thought would be a 'one-off' and it became more useful than I thought and ended up writing a GUI for it, or I've need to come back to use a program months later. The advantage of the GUI is it makes it easier to remember what would otherwise likely be command line arguments. I.e. for flags and options you can simply use check boxes, combo boxes, radio buttons, and file selectors filenames. I use Borland C++ RAD so it is quite quick and easy to throw together a simple (or even not so simple) dialog box. I now often start with creating the GUI.
If you use Linux, try Zenity. It's an easy to use tool to make a GUI for command-line programs.
