How to customize intentions in PyCharm (e.g. modify "After" code) - intellij-idea

PyCharm (and the other IntelliJ IDEs) have the idea of intention actions. One that I want to customize is the "Insert documentation string stub" so that it includes type annotations. I can't type in the After section or find a menu that allows me to modify it at all - is that possible? If not, is there another plugin or something that will allow such a modification?

You can not customize intentions. But you may use Live Templates, they are very customizable: https://www.jetbrains.com/help/idea/2016.1/live-templates.html

Intellij refactoring, disable/customize generating "#org.jetbrains.annotations.NotNull"

Every time I extract method, this line is generated "for me":
#org.jetbrains.annotations.NotNull
around the method. 1. I don't have this on my class path, so it does not compile 2. even if I have, I don't want to include jetbrains annotations in my project. Even if I have more suitable (maybe) javax.validation.constraints.NotNull annotation on class path, intellij does not use that one.
questions:
how to turn it off entirely?
how to customize, which annotation to use?
The extract method dialog has a Generate annotations check box. When disabled it does not generate the nullability annotations. The state of this check box is remembered between invocations, so disabling it once is enough.
If this check box does not appear, annotations for the extracted method should not be generated.
It is possible to customize the annotation used in the settings of the Java | Probable bugs | Constant conditions & exceptions inspection. The configuration dialog looks this:
Use the check mark button, to mark the selected annotation as the one that should be used for code generation.
I ran into the same problem and was able to fix it by follow these steps :
Go to Settings > Editor > Inspections >
Find Java > Probable Bugs > Nullability Problems > #NotNull/#Nullable Problems
Click Configure Annotations button and check these items

IntelliJ Plugin Development: LookupElement with class preview

For a custom language I created a CompletionContributor. Everything works fine. But I'm limited to the information I can display (only in the list or the bottom "advertisement" and only 1 line).
When trying to auto-complete on a java class name it will display more information on the selected line in a small side window. I would like to exploit that mechanism but I really don't know how it is done.
When looking at the options provided, I can use a custom LookupElementRenderer but there is no method in LookupElementPresentation related to the right window.
Any idea how it is done?
Are you referring to documentation popup which may be displayed if the corresponding setting (Setting->Editor->General->Code completion->Show the documentation popup in) is turned on?
If you want the feature to work for your language you have to use lang.documentationProvider extension point.

How to make auto completion in WebStorm (*.js) and IntelliJ (*.go) work the same

In WebStorm I can type something like
document.gEBI
press tab key, and it'll autocomplete to
document.getElementById()
But when I do the similar thing in IntelliJ
fmt.Prl
Auto completion doesn't work (the desired result fmt.Println()) at all, it works only if all the letters match strictly in order.
Is it possible to enable this functionality in IntelliJ? I've imported all the settings from WebStorm.
These Tab key shortcuts aren't part of the auto-complete system the Jetbrains use for all their IDEs as LazyOne says, they are actually part of the template-invocation system.
The auto-complete functionality is built into the shortcut: Ctrl+Space.
I suggest looking up the template invocation for .Println() in the settings, Jetbrains documentation, or raising a ticket with Jetbrains on YouTrack for clearer documenation/control over template-invocation.

CodeLens style in-context information in IntelliJ IDEA

For a while now, newer versions of Visual Studio have been able to display in-line information for methods, fields etc relating to how many times they may have been referenced or changed and who changed the code last. This feature is known as CodeLens.
Is there any plugin or feature in IntelliJ IDEA similar to this that would be able to display information on an individual class/field/method basis?
(22-Aug-2022 updated) The hints from git blame are also available in the latest IntelliJ IDEA.
==================
(For CodeLens function references feature) Now it's a built-in feature after version IntelliJ IDEA 2020.1.
You can enable it from:
Ref: https://blog.jetbrains.com/idea/2020/03/intellij-idea-2020-1-beta2/
There is no such plugin (yet).
You can of course right click the left gutter (gray editor to the left of the editor) and select "Annotate". That gives you at least the last edit per line.
More similar to your desired feature (but unfortunately not inline):
Select some text (e.g. a method), then right-click Git -> Show History for Selection.
Now there is JetBrains plugin named GitToolBox.
It has some similar functionality, including the current line "blame annotation" at the end of the line with detailed commit information:
This feature is available for Rider, but not for IntelliJ yet.
In Rider it's called Code Vision

Editor context Menu - Eclipse-RCP

I have an Eclipse RCP application. I have created an Editor. There are few context menu (default), when I right click on the Editor. I have not created these menus.
Please let me know, How to remove the context menu of the Editor?
It needs different approach by which editor you extends.
Let me know What you extends, than I can answer more efficient one.
In general way:
IWorkbenchParSite#registerContextMenu(...) will be used, So find where calls that, override it. It is not recommend. Because by doing this, Menu Extensions which is contributed for your editor will not work anymore.
If you mean the system menu that appears on editor tabs and view tabs, that menu is provided by the presentation (2.1, Classic, Default, etc). There is no tweak to simply modify it.
The 2 ways to remove it would be:
write your own presentation, using
the
org.eclipse.ui.presentations.StackPresentation
API and matching extension point.
Writing a presentation is a involved
undertaking.
Change the internal classes in the
org.eclipse.ui.workbench plugin
and patch that plugin in your RCP
app.
If you use Text or StyleText you will get the system default menu (cut,copy,paste, maybe something about encoding or input). If you are not going to supply your own menu, simply create an empty SWT Menu and set it:
Menu emptyMenu = new Menu(text);
text.setMenu(emptyMenu);
Eclipse also has a text editing framework, if you need more than a basic text box you should check it out. http://wiki.eclipse.org/The_Official_Eclipse_FAQs#Text_Editors
