When I work with certain types of files, such as: Java file, HTML file or Jasmine Test file I can generate some useful code snippets using Code > Generate option, for example:
if I am working with Java file Code > Generate allows me to insert getter, setter, constructor etc
if I am working with HTML file Code > Generate allows me to insert an XML tag
if I am working with Jasmine Text file Code > Generate allows me to insert a scaffolding of a test suit or a singe test case
I was wondering if (and how) I can add my own 'generator'. I know I can use Live Templates, but I like the fact that Code > Generate gives me a quick list of all available generators.
Yes, you can do it by writing an IntelliJ plugin and extending this class:
com.intellij.openapi.actionSystem.Action
If you create an intelliJ plugin project (just google intellij plugin developmentfor information on how to get started), hit alt-enter somewhere in your project source tree and select Action, you will get a dialog which allows you to configure where your action should appear.
You want to place it in relation to another action which already exists, for example right below it. In your case - have a look at the menu group named GenerateGroup (Generate).
Once your action is defined in this manner in your plugin.xml, build and run your plugin in the sandbox.
Now, when your action is triggered, the AnActionEvent will be fired which contains references to all the necessary information you need (current project, file, position of cursor within file, psi tree, etc).
Try to get this working so far and come back with any specific questions.
Good luck!

My angular code is organised into separate directories, one for each component. Each component has its corresponding spec.ts. How do I run specs from only one particular file using IntelliJ. It is not practical to mark each test case as fdescribe and fit. Is there a menu option which can let me do it?
I have a maven project in IntelliJ IDE. I have created a package with name event.handlers. After which I created multiple classes inside this package.
There are no classes inside event everything is inside event.handlers.
Now I want to create a java class inside package event.
Is there any way from the IDE I can do that?
Currently, I am manually creating the java file inside the event folder in my code repository.
In the left Project structure pane, there is Settings button, in that please Uncheck, Compact Empty Middle Packages.
The settings will be like
.
Now you will have a tree structure, where you can right-click or (ctrl + enter/ alt + insert) on the package and create the file.
For example,
Try creating a Java Class at src folder named event.NewClass. This will create a NewClass.java inside src/event.
You can create folder with the dot symbol . at creating a Java Class or a Package, or Kotlin File/Class when Type is not File. For example create a Package with name com.company.example at src folder will automatically generate the folders recursively, src/com/company/example, create a Java Class with name com.company.example.AClass will automatically generate a file AClass.java inside the automatically generated folder tree src/com/company/example.
It might be easier to just create the class inside package AB and Refactor > Move to place it inside of A.
It seems that all other answers here are workarounds anyway, so if it's just a one-off, this might be the easiest option.
However, in my case, after doing this I had to "Invalidate Caches and Restart" before IDEA updated the UI properly.
Could any body let me know how to create custom widget in thingworx.
I don't have any idea how to create custom widget.
Please help me.
I have to build drag drop custom widget and we can use that custom widget with other widget. e.g with tree widget,... etc.
I would recommend reading the official Extension Package Development Guide:
However, the best way to start making a new widget is to take an existing widget that does something like you want, and modify it. Built in widgets exist at
TomcatRoot\webapps\Thingworx\Common\thingworx\widgets
Here's a very brief guide to getting started with that. If you were to want to copy Textbox:
Open the metadata.xml and change the "TextBox" to "MyWidget".
There are two sections in this file. The "ExtensionPackage" section holds metadata for the pacakge (version, vendor, etc.)
The second section , "Widgets" defines the widget files. Change the name of all these files to use your name e.g. MyWidget.ide.js Don’t forget to change name in the “Widget” xml tag too.
Rename all necessary folder and files, replacing "TextBox" with "MyWidget"
Open the both .js files and change the definition in each to reflect "MyWidget"
In the ide file, change the icon path "widgetIconUrl" and the "name" property.
Select the "ui" folder and the metadata.xml file and package them both into a new zip file. This file should import into Thingworx.
I would suggest searching for or asking this question in the PTC IoT Community, which is much more active for Thingworx developers than StackExchange.
UPDATE: The latest documentation for ThingWorx 9 Extension Package Development Guide can be found here
I try to add external library to my current project, but my project can't pick up the library.
I have MyLib.java file in other directory.
/Users/cat/myfile/github/JavaLib/MyLib.java
I want to my current project (/home/project/HelloWorld/HellowWorld.java) to use my MyLib.java
I'm following the steps to add Library to Intellij(15CE)
Menu->Project Structure->Libraries
click (+) symbol->select Java -> select my path(/home/lib/)
Here is the screenshot
Now that you have added your JavaLib directory to the project you should be able to use the code inside JavaLib in your code now. Intellij should offer auto-complete when you start to type the name of a JavaLib class and automatically include the import for you in your code.
The disabled Apply button you circled isn't an issue. I get that in my view too. It just means nothing has changed that needs to be applied currently.
I recently attended a user group meeting where the IntelliJ representative was demonstrating version 13.
He demonstrated how to switch the code completion view of a file. I do not exactly remember what the file extension of this particular file was, probably java.
The concept was that if the file is html with embedded javascript he could then switch the code completion between html and javascript with a shortcut. If he says treat the file as html then all code in file was treated for code completion purposes as html, and vice versa for javascript.
Does anybody know what shortcut he might have been using to enable the language switch?
Sounds like you may be referring to the IntelliLang feature. IntelliJ IDEA can be aware of other languages embedded within a file.
A simple example is in an HTML file that has CSS and JavaScript.
Notice when I am inside the HTML markup:
or inside an HTML element:
The code complete shows HTML completion options. However, when I am inside the style attribute, I get CSS code completion:
I also get CSS code completion if I am inside a <style> element. So even though I am in an HTML file, I see CSS code completion because of my location.
Same case with JavaScript. When I invoke code completion inside a <script> element, I get JavaScript completion, even though I am in an HTML file.
Anytime IntelliJ IDEA can determine that another embedded language is present, it provides, via IntelliLang, the appropriate syntax highlighting, error highlighting, and code completion. The same holds true for Java. Notice here that IDEA knows the method I am competing takes an SQL statement and therefore highlights the String value using SQL highlighting, and provides SQL code completion:
So even though I am in a .java file, I get SQL code completion. The reason is that IntelliLang comes pre-configured knowing the embedded language of some methods. You modify them, or add more, in File > Settings > [Project Settings] > Language Injections.
In addition, you can use an annotation to tell IntelliJ IDEA (as well as developers looking at the code) that a String must be valid in a particular language. For example, I can annotate a String field, variable, or parameter, to indicate it must be valid HTML:
Notice I get HTML syntax highlighting, HTML code completions, and the CSS color shows in the left gutter. If I annotate a method parameter, then any time I call the method, I get the appropriate syntax highlighting, code completion, and error/warning highlighting:
The #Language annotation is inside the annotations.jar that is contained in the redist directory inside the IntelliJ IDEA installation directory. It is also available in maven central, or IDEA will offer to attach it as a Library if you use the annotation without it being attached.
IntelliLang and the #Language annotation supports a large number of languages. Just use code Completion inside the quotes after typing #Language("") to see a list. (Inline search works in the list as well.) One of the most useful is Regexp. For example, if you have a method that expects the string passed in to be a valid Regular Expression, annotating it as such will give anyone that calls it Regex code completion and error highlighting if they are passing in an invalid Regex pattern. Even for developers using other IDEs it is useful as a form of documentation.
As for a shortcut to change the the language on the fly for code completion, the only thing I can think that you might be referring to is the "Inject Language" intention. If I am entering a String value, and I bring up the quick-fix/intention menu via Alt+Enter, I am given an option to inject a language:
If I select that, IntelliJ IDEA will ask me what language I want to use:
After making my selection, IntelliJ IDEA will give me temporary language injection (including code completion) for the selected language.
It also gives me an option to add the #Language annotation for permanent injection.
To the best of my knowledge (as a 10 year IntelliJ IDEA user) that is the only way to switch code completion language types. So hopefully that is what you are looking for. To me, IntelliLang is one of the coolest features in IntelliJ. (It actually started as a third party plug-in and JetBrains then absorbed it into the product.)
