In our code base there are a few very long methods (several pages worth of code). When reading the code, it would sometimes be good to be able to see the name of the method the current line belongs to, without paging up to the beginning of the method. Is this possible in Intellij IDEA? I am using Intellij IDEA 7.0.3.
You can use View | Context Info (Alt+Q, Ctrl+Shift+Q on Macs). It will display a pop-up on the top of the editor with the current context information (class/method signature).
IntelliJ 2018
This is shown by default at the bottom.
Unfortunately, the method is shown only by name (not including the parameters). If a method is overloaded you won't know for sure where you are.
If you want to move it from bottom to top, go to File > Settings... > Editor > General > Breadcrumbs > check Top:
In the structure panel select the "Autoscroll from source" option.
This way when you place the cursor inside any method the structure panel will show which method you're in.
Intellij now has support for breadcrumbs. Go to settings > appearance and tick "Show breadcrumbs". In this way you can view class/method name without Alt+Q.
For some reason (Alt-Q) wasn't consistent in Android Studio for me. I find (Ctrl-F12) to be pretty satisfactory for this purpose (Navigate|File Structure) though it can be a little laggy in larger files. And by pressing the hotkey again it will populate the list with all the inherited methods as well.

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.
I want to use code snippets in VSCode. But when I type, for example, for in javascript file, the Intellisense doesn't suggest snippet "for-loop" - I need to manually scroll the dropdown and select it. Is there any way to make VSCode to suggest snippets at first? Thank you!
UPD: I have found the person with same problem, but he has no answers - link
You need to use editor.snippetSuggestions config option with "top" value. Please, see Customizing IntelliSense article for more tips and tricks.
There is one more way to deal with this issue by setting
"editor.tabCompletion": true,
that way whenever there is a snnipet available it will use it automatically without even opening the list by using tab twice.
File > Preferences > Settings (Code > Preferences > Settings on Mac)
open "Editor" menu on the left
edit "editor.tabCompletion": true
more info: https://code.visualstudio.com/docs/editor/intellisense#_customizing-intellisense
Now that VS Code mostly abstracted away the settings.json file, you can do the instructions shown by Kavu, with this bonus tip:
go to Preferences > Settings
find the Search settings text input, at the top
type in "snippet"
The setting should be at the top of the result set:
Setting editor.snippetSuggestions to top only works for certain snippets: for but not foreach. With top, the snippet does appear higher in the completion list, but for some reason the keyword version is what is highlighted, with the snippet option scrolled out of view (and the scrollbar quickly fades, giving the impression there's nothing hidden)
The editor.tabCompletion to true approach works for both for and foreach.
I hate to ask such simple questions, but nothing I found so far helped me...
So, I've recently started using IntelliJ instead of Eclipse and there are 2 things that really bothers me...
1.) size of javadoc popup window - ok, so I finally get this little guy to pop-up whenever I need it, but it's so small I have to use scroll every single time... and that's pretty anoying when I'm working with unknown libraries...
2.) tabs == spaces - maybe some of you like this, but I don't... Eclipse was treating tabs as tabs and not spaces... I tried to change settings but with no result... or is that maybe connected with project I'm working on? (meaning, if, at the start of a project, setting were such that tabs == spaces and now changes are not applied to it)
Sorry for stupid question but, as I said, nothing I found so far helped me...
1) Just resize the window with your mouse. It will retain the size the next time it opens. You can also click on the gear icon in the upper right corner and adjust the font size. Again, it will retain the size on subsequent use.
2) I'm assuming you make the change to the "Use Tab Character" option on the "Tabs and Indents" tab for all file types and saved the Code Style. After that, you need to run the Reformat Code action (Ctrl+Alt+L or Code > Reformat Code from the menu or Reformat Code from the context menu (i.e. right-click) in The Project Tool window or Navigation Bar). IDEA retains the previous formatting (so spaces in this case) until you run a reformat on the project (or a part of it).
If you have multiple projects already created, for each one, you will need to go into File > Settings > [Project Settings] > Code Style and set the Scheme (and then do a reformat). While the Scheme definition is saved IDE wide, the scheme to use is set per project (which makes sense since an Apache Open Source project you are working on may have different code style requirements than the projects you do at work vs the ones you do for fun).
Finally, you will also want to go into File > Other Settings > Default Settings > [Template Project Settings] > Code Style and make sure your saved code style scheme (with the use tab option) is set so that new projects use that scheme when they are created.
I've a question. I cannot find the way, how to add buttons to main toolbar programmatically. My problem is, that I've the task to dynamically (based on XML configuration file) build menus and toolbar. I found how to add a menu item programmatically, but not toolbar button.
Tutorials mostly show how to create buttons and menus using plugin descriptor (plugin.xml), but not how to do it programatically. It seems, that it is out of bounds of Eclipse plugin philosophy.
I've just found this:
There might be layout problems with this approach. I also don't
believe the framework will try and re-create your dynamic item except
at random toolbarmanager updates. With Menus they can be updated on an
SWT.Show event, which is why CompoundContributionItem only applies to
Menus.
What shall I do? Can I say Sorry, there is no way to build toolbar dynamically. I can do it just for menus? Collegue says, that it must be possible, but he does neither know how.
The only way to be able to create main toolbar entries programmatically is in an RCP app, where you supply the ActionBarAdvisor for the workbench window. This isn't dynamic, however, just called on window creation.
Another way to do it would be to use org.eclipse.ui.menus and contribute org.eclipse.ui.menus.ExtensionContributionFactory. It also works only on workbench window creation (not really dynamic), but you could read your own XML and provide IContributionItems for the main menu or toolbar.
How dynamic are you trying to be? Most solutions work well on startup/window creation.

Whenever you try to do something programmatically in Eclipse that is normally done through plugin definitions you are walking on thin ice. I've tried it on a few occasions and it rarely ended up being easy or good.
Instead, think of what it is that you only know at runtime and need to be able to change on the fly. Is it the name or icon of the button? That can be changed at runtime.
Take a look at runtime commands, they can be confusing to define properly, but with them you can for example create buttons that are only visible if a condition is active. That condition could be set at runtime.
I'm Using resharper 6 nighty builds and VB.net. I've a big medium project with multiple files that don't follow the code style conventions of my company.
I've configured resharper with my own convenctions and It suggest to me the right name for each variable (perfect!).
But I can't find any automagic way to make the current name to be replaced with the suggested name.
Are there any way to do it? If not ... did you know ane fearure of coderush Xpress to achieve it?
Thanks.
If you've configured ReSharper with your naming conventions, then it should show a warning (blue squiggly underline) under any identifiers that don't comply. If you put the text cursor on one of those misnamed identifiers, you should see a pyramid icon appear near the left margin. Then you can press Alt+Enter (or click the pyramid icon) to drop down a quick-fix menu. There should be an option in the menu to "Rename to '_myField'". Usually it's the first item in the list, so you can just press Enter again to do the rename.
If you want to do this on everything in a source file, you can use the ReSharper > Inspect > Next Issue in File command (or its keyboard shortcut -- F12 in the IDEA keymap) to move the cursor to the next warning in the file. Then, if it's another name warning, you can use Alt+Enter, Enter again to fix it.
Unfortunately, there isn't a way to automatically fix every instance of a warning at once (though it's been requested; please feel free to vote for RSRP-126551 in their issue tracker).
