One way to comfortably use an IDE in an interactive language is to interact via the IDE in a command line environment. I am wondering if that is a possibility in Juno. In other words, is there a command line environment as in Matlab, to call functions, give initial values, and run expressions. If so what is the way to access it?
Note: There is a console window in Juno, but I can't find a way to insert my commands inside that.
Note: The question and this answer apply to the version of Juno that was based on LightTable. The current version is based on Atom and has an interactive console.
You can't enter commands into the console in Juno--that's for displaying output. Commands can be submitted from within the editor by setting your cursor in the line to submit and pressing Ctrl+Enter or Shift+Enter. The value will then be displayed in a small popup next to the line and the output will be printed to the console if you have the console visible.
Note that the inability to use the console as you desire is by design. See here for information about the console from the Juno docs.

I'm using JetBrains GoLand IDE however I assume the answer would be common for any JetBrains IDE such as IntelliJ etc.
I've configured file watchers for:
go fmt, golint and go test
go fmt does not have output so it works fine.
golint and go test both have output. If I enable just one of them I see that output. If I enable both I see the output of golint for only a split second then it is replaced by the output of go test So I will never actually be able to read the output of golint
For now I solved this by making go test only display output on error, if it errors I figure I do not yet care about the output of golint but thought I'd ask anyway.
You don't need to enable go test as a File Watcher as the default test runner can execute on file changes.
To enable this feature, you can enable the Toggle test auto-rerun feature, which is the third button from top to bottom on the left side of the run test window. You can also configure the interval after which the tests run via the cog wheel.
Here's a reference for how to do this in IntelliJ IDEA, which is the same as in GoLand https://twitter.com/intellijidea/status/807239309992591361?lang=en

How can I step back to a previous line when I'm debugging in IntelliJ?
I don't see anything in the debug menu or commands to do this.
There's no backward debugging support in IDEA currently. Nevertheless (for Java) there is Drop Frame action and button on the debugger toolbar. It lets you go one frame up in the stack and re-enter the current method.
The Chronon plugin, which is available for free with IntelliJ IDEA 13, can do this for you. It has limitations, though; chiefly, if your application runs outside of the IDE itself (like a Tomcat or Jetty server), the free version won't be usable with your setup.
I am trying to test a website which contains alot of javascript.
Javascript does alot of opening new dialog to let user choose "yes" or "no".
It also has a function to upon right clicking, it opens up a right click menu which contains many functions such as zip, delete etc.
In Selenium, I can use the Selenium IDE to login, click, and others, but I don't know how to test those functions.
I've read there are codes I can write such as in Java to run the test, but I'm hoping to make it work by using the simple Selenium IDE if possible. If not, then can someone post a simple testing code which works to run java scripts? Such as click button -> javascript menu pops up -> click ok on the pop up.
Thank you very much.
Right context menus can be a little tricky. I'd suggest making custom commands for the right click context menu. Add the code from this article to your custom user-extensions.js file.
http://old.nabble.com/How-to-recognise-right-click-of-the-mouse-in-IDE-td14913052.html
The parameters for these functions in these commands become the expected arguments of your Selenium IDE commands. If you really want to make it simple, you can just call your javascript functions in these custom user-extension commands. :-) That might be a bit lazy and isn't truely testing what your right click is doing, but it would work.
Option #1 - if using IDE:
Specify the user-extensions.js file under Selenium IDE > Options (menu) > Options (menu option) > General Tab, then browse to your file under "Selenium Core Extensions".
Option #2 - if using Selenium RC Server:
If you're not using the IDE and using Selenium RC server with a client driver (like JUnit for example), you must specify the path of the *.js file with the -userExtensions parameter when you start the Selenium RC Server on the command line. But you said you just wanted to use the IDE, so I'd ignore this. It takes quite a bit of other setup to use the Selenium RC server.
java -jar selenium-server.jar -userExtensions user-extensions.js
=======================
I've never done this before, so I made the following custom command (JavaScript function) in my custom user-extensions.js file, and it worked well for me. I had to exit and restart the IDE before it found it. For some reason, you type everything after the "do" in the "Command" field in the IDE. It looks like it also added a "customAlertAndWait" to the IDE as well.
Code in user-extensions.js file:
Selenium.prototype.doCustomAlert = function(sTarget, sValue) {
alert('Target: ' + sTarget + ' ... Value: ' + sValue);
};
Selenium IDE command details:
Command: customAlert
Target: custom alert target
Value: custom alert value
The selenium IDE has a lot of tools to verify that specific elements are present and that the value is correct.
To set something up, you would create a test case, and start to record it. When you get to a page where you have to verify that something exists, right click on that element, and you will see a lot of Selenium commands tagged at the bottom of the click menu, such as "VerifyTextPresent" or "verifyValue" or "verifyElementPresent" When you select those commands, they will appear in your test case, and will fail if the verification fails.
A keyboard shortcut to comment/uncomment out a piece of code is common in other programming IDE's for languages like Java, .Net. I find it a very useful technique when experimenting through trial and error to temporarily comment out and uncomment lines, words and parts of the code to find out what is and isn't working.
I cannot find any such keyboard shortcut on the Mathematica front end in version 7. I know that it is possible to comment out code by selecting the code, right mouse click and select Un/Comment from the menu that appears but this is too slow while coding.
I tried to access this using the menu key Menu on the keyboard but Mathematica frontend doesn't respond to or recognise this key unlike other applications, this could have allowed a key combination for commenting. Can someone else verify that this isn't unique to my machine and that the key isn't recognised by mathematica. I looked at this question and looked in the KeyEventTranslations.tr file but I don't think there is any way to create a shortcut to do this(?). Should I just live with it?
Any other suggestions?
(I have seen there is an Emacs version of mathematica, I have never tried Emacs or this Mma version and imagine that it would have this ability but would prefer not to go to the trouble and uncertainty of installing it. Also I would guess that the Wolfram Workbench could do this, but that may not be worth the investment just for this.)
You can install the shortcut in Mathematica 7.0.x if you are willing to edit the Mathematica system file MenuSetup.tr. You can find it in the same location as the KeyEventTranslations.tr file (i.e. in the installation under "SystemFiles/FrontEnd/TextResources/platform"). In MenuSetup.tr, locate the following line under the definition of the Edit menu:
MenuItem["Check &Balance", "Balance", MenuKey["B", Modifiers->{"Control", "Shift"}]],
Immediately below that line, insert the following:
MenuItem["Un/C&omment Selection", KernelExecute[FE`toggleComment[]], MenuKey["/", Modifiers->{"Command"}], MenuEvaluator -> Automatic, Method -> "Queued"],
The Un/Comment Selection command is now available under the Edit menu, with the keyboard shortcut Cmd-/ or Alt-/ depending on your platform -- just like in Mathematica 8 where this command comes pre-installed.
Please take as read the usual disclaimers about hacking the Mathematica installation files -- no warranty is offered :)
I do not know of any way to map this function to some shortcut involving the Menu key.
Shortcut Key, No Menu
The preceding steps mimic what Mathematica 8 does by installing a new menu item. If you prefer to leave the menus unchanged, then you can install the shortcut in KeyEventTranslations.tr instead. Add the following line:
Item[KeyEvent["/", Modifiers->{Command}], KernelExecute[ToExpression["FE`toggleComment[]"]], MenuEvaluator -> Automatic, Method -> "Queued"]
You'll need a comma on the end of that line if it is not the last item in the list.
Select the code and press one of the following:
Alt+/
Alt-E-O
Alt+E+O
Notes:
Tested only on Windows, using Mathematica 8.
On my non-US keyboard (ABNT Brazil), the shortcut Alt+/ doesn't work, instead I use Alt+E+O.
Here is code for your KeyEventTranslations.tr file that will comment out code. I am still working on the other half.
Item[KeyEvent["/", Modifiers -> {Command}],
FrontEndExecute[{
NotebookApply[FrontEnd`InputNotebook[],
"(*\[SelectionPlaceholder]*)"
]
}]
],
This binds it to Alt+/ as it is in Mathematica 8.
I am trying to extract the contents of cmd.exe IDE to a text file using autohotkey scripts ie one test.ahk and its written as shown below:
WinGetText, text, "C:\WINDOWS\system32\cmd.exe"
FileAppend, %text%, C:\ThreePartition\ACTUAL.txt
I am not able to extract the contents. Can anyone please suggest the correct way to do the extraction?
The text retrieved is generally the same as what Window Spy shows for that window.
The Window Spy shows no text elements for CMD windows - what you see is not necessarily what you can get :)
What you can do is to simulate the Select All and Paste commands, and then use the clipboard contents.
I don't believe you can extract the contents of a cmd window without somehow using DllCall to read the process memory directly.
If you just want the output of a CLI command such as Grep or AWK, using stdout via the run command should work. Honestly though, I stopped relying on AHK because this sort of thing is just too clunky.
http://www.autohotkey.com/docs/commands/Run.htm.
Edit for comments:
What you want is doable, but the solution depends entirely on how your IDE works. What behavior does it have that's unique to building a project? If it makes temp files, you can overload your "build" button with an AHK subroutine that watches for the existence of those files, and then checks the modified date of the output executable to see if the build succeeded. The same kind of solution works if the IDE changes its window title when building. Be clever. :)
Failing that, you might have to install a message hook.
