Whenever I write an auto-completed function call and start typing something, a black rectangle is drawn around the input, like below:
Why does eclipse do this and how can I turn it off? I've looked the different editor settings but I haven't found anything that describes this behavior.
This is called place holder. Keep caret anywhere in between the class methods and inside the class body and type public and press Ctrl + Space and select public_method option. Then you will get a template looks like this:
Here return_type is covered with rectangle and highlighted this means you can type the return type as void, int etc and this will appear in this rectangle box.
Use TAB key to traverse next place holders i.e name is also covered with rectangle box. After typing the return type when you press TAB key you will jump to next place holder(i.e name).
You can go back to the previous place holder by pressing Shift + TAB key. Green color caret represent the end of place holders.
While you are in any place holder if you press Enter key you will be directly taken to the end of the place holder(i.e green caret).
Check the template grammar for public_method template here Windows > Preferences > Java > Editors > Templates
It looks as
public ${return_type} ${name}(${}) {
${cursor}
}
You can edit this. If you remove ${cursor} then green colour caret will not appear and so on.
You can turn if off by
Deleting template(Not recommended)
Editing template grammer
Or just by pressing Enter key(Recommended)
Also check the grammar of static_final template. Here you will get the drop down menu along with rectangular box.

I'm writing a language extension and I need to know what the current selection inside the completion prompt is
example
For example, in the b, d options in the figure, I need to automatically fill the selected CompletionItem.label characters to before the / character after entering the / character, please help, I have been looking for several hours
Using executeCommand can only get the return value, and the editor will not display the selection
vscode.commands.executeCommand("vscode.executeCompletionItemProvider", ...)
I have tried to monitor the up and down direction buttons, but I found that using the contributes.keybindings in package.json to bind the buttons will cause the cursor movement to fail
The ultimate goal is to add the string current selection/ to the editor after entering the / character
This is a similar effect, I only entered ., without pressing Enter
enter image description here
I have the following requirement (sorry, but I'm quite new to JavaFX).
I need to have a custom TextArea that supports not only entering text but also entering a kind of macro.
This Macro has a unique ID and an associated text. The text should be displayed in the TextArea but with an e.g. light grey background. This is because it should behave as a unit.
You should not be able to click inside the macro and add a char there. The cursor should be placed behind the macro. And is you press just backspace the complete macro should be deleted.
If you call something like getRawContent() of the custom TextArea you should get a placeholder for the macro and not the associated text like:
getRawContent()
==> "This is text part one MACRO:132 This is text part two"
If the macro 132 has the following text associated "XXX123XXX", you will see inside the custom TextArea:
This is text part oneXXX123XXXThis is text part two"
But the text XXX123XXX has a light grey background to show that this text is associated with a macro and could be deleted, copied, and so on as a whole unit. Could be italic as well as in the above line. Should be only a bit different to the generic text.
Could someone assist me?
My Custom Control works now. I used an Eventfilter to prevent the internal Eventhandler to process the keypressed events in order to set the caret position behind a macro or delete the complete macro when DEL or BACKSPACE is pressed, this works.
And I use a Mouselistener to prevent that someone clicks and set caret position inside a macro.
So now I have only the problem left to mark the text somehow that the user can see what is normal text and what macro content.
Maybe I close here and open a new question.
Hello I was wondering how to create sub-headers in an org document. I have tried this:
* header
* sub-header
Some text
The * works for the header part but will create bullets instead of sub-headers.
for these kind of questions the org-manual is the best place to check: https://orgmode.org/org.html#Headlines
Headlines define the structure of an outline tree. The headlines in Org start with one or more stars, on the left margin3. For example:
* Top level headline
** Second level
*** Third level
some text
*** Third level
more text
* Another top level headline
Hope, this helps!
As a supplement to the answer by #sanenr9, you can also enable a "clean view" that hides all but the last star in a heading if you prefer (see A Cleaner Outline View): the asterisks are still there in the buffer but they are hidden using an overlay.
Another useful hint is to examine the "Org" entry in the menu: there are many useful commands there (generally with a keyboard shortcut as well). E.g. you can add a new heading at the same level as the previous heading by clicking on the "New Heading" entry in the "Org" menu and you can then make it into a subheading by clicking on
"Org/Edit Structure/Demote heading" menu item (or you can use the indicated keyboard shortcut M-<right> which is done by holding down the Meta key and pressing the right arrow key.)
Let say I have a text like this
> Name
>
> Peak
>
> Surname
>
> Sornpaisarn
But I want the whole document to be written like this
Name Peak
Surname Sornpaisarn
So for the odd blank space, I want to change to tab. For the even blank space I want to delete it. Are there anything in vs code that can do that?
Make sure the final line is just >, so that the final key-space-value-space chunk is the same as the others
Make a backup copy of your page. If the edit ruins it, you can replace it and try something else
Choose "Replace" from the Edit menu
in the find/replace dialog, click the little .* box to turn on regular expressions
in the top (find) box, enter >\s([^\n]+)\n>\n>\s([^\n]+)\n>
in the bottom (replace with) box, enter $1\t$2
click in front of the first character in the file so you'll start the conversion there
click the little "replace" or "replace all" buttons (little b -> c icons to the right of the "replace with" text)
I want to edit multiple lines in eclipse, but I can't find any short cut or Plugin. In Geany I just press ctrl+alt+up/down I can add / edit multiple lines.
Maybe this example can explain what I mean:
var text = "myname";
var addr = "myaddr";
var age = "myage";
I want to edit text above into:
var my_text = "myname";
var my_addr = "myaddr";
var my_age = "myage";
The text above is just a simple example, but sometimes I have many lines of words that I have to edit its prefix.
Press alt + shift + A to Toggle block selection (Toggle block / column selection in the current text editor), this will let you write vertically in eclipse, then you can easily do this.
Go to Window->Preferences.
Find for binding in text box surrounded by red box.
On OS X, the key combination for multi-line edits in Eclipse (or STS) is option/alt+command+A
You can try the following plugin,
https://github.com/caspark/eclipse-multicursor/releases
With this multiple occurrence of same text can be selected and edited. This is similar to multi select functionality available in editors like Sublime and Visual studio code.
The Eclipse 4.24 (June 15 2022) will integrate it (See https://bugs.eclipse.org/bugs/show_bug.cgi?id=576377):
Multi selection down relative to anchor selection (e.g. Ctrl-Alt-J)
Multi selection up relative to anchor selection (e.g. Alt-J)
End multi-selection (e.g. ESC)
Add all matches to multi-selection (e.g. Ctrl-Shift-Alt-J)
Multi caret up (e.g. Ctrl-Alt-Shift-Up)
Multi caret down (e.g. Ctrl-Alt-Shift-Down)
Thanks to eclipse contributor !
The Eclipse 4.22 (Q4 2021) equivalent of Geany would Alt+Click on the lines you want to edit in one go.
Eclipse now supports
Multiple text selection
Support for multiple selection has been added to Text Editors.
Multi selections allow most edit operations (text replacement or insertion, extend selection to next word or to next line, copy/paste...) to apply simultaneously on all ranges.
Multiple strategies are available to enable multi-selections:
Turn a block selection into a multi-selection using the To multi-selection command,
Add a caret with Alt+Click,
Use the new Select All button on the Find/Replace dialog.
So check if this would work in your case.
I know this is an old post, but I still want to share my way of multi select and editing. However this way is restricted to only the same variables across the file. Simply highlight the variable to edit, right click, choose Refactor->Rename. Then edit the variable and it will also edit the same variables across the file. Hope it helps..:)
Press key - { Alt + Shift + A } You will see A [+] symbol in IDE then use this symbol as drag
