I am implementing refactor action for my custom eclipse editor. When the file is renamed, I reset the editor input based on the renamed file and also update the part name.
However the editor references still hold the previous input and file names. Thus eclipse does not know changes to the editor window and cause problems later on like "empty editor tab" exceptions.
How to update the editor references for refactor actions on eclipse editor?
In your class derived from EditorPart do something like:
IEditorInput input = ... new editor input
setInputWithNotify(input);
setPartName(input.getName());
firePropertyChange(PROP_DIRTY);

I'm building a VS Code extension which includes changing the name/title of untitled-1 tab (unsaved file).
I tried running the below code in debugger console of extension but it didn't reflect in the editor:
vscode.workspace.textDocuments[0].fileName="myFile"
Is it not possible or am I missing something?
It is still (Q1 2020) not possible, but the next VSCode 1.42 will name its Untitled editors differently.
Untitled editors in VS Code are text buffers that have not yet been saved to disk.
You can leave them open for as long as you like and all text content is stored and restored between restarts.
Untitled editors were given generic names such as Untitled-1 and counting upwards.
In this release, untitled editors will use the content of the first line of the document for the editor title, and include the generic name as part of the description:
Note: If the first line is empty or does not contain any words, the title will fall back to Untitled_* as before.
So while you cannot set the title yourself (still readonly fileName), technically... changing the first line of that file would be enough to change the title of said "Untitled" editor.
With VSCode 1.43 (Q1 2020), a new setting workbench.editor.untitled.labelFormat allows to control whether untitled editors should use the contents as title or not.
Possible values are content or name.
Configure 'workbench.editor.untitled.labelFormat': 'name' to get the previous behavior back where untitled editors would have a short title, such as Untitled-1.
It's not possible - if you check out the source code for the API definition in vscode.d.ts, you'll see that fileName is declared as readonly:
export interface TextDocument {
// ...
readonly fileName: string;
// ...
}
Unfortunately, it seems that the readonly attribute isn't reflected in the API docs on the website.
This mainly happens if we create a new file in the OPEN EDITORS section, thus they appear as unsaved. To prevent this, create a folder for storing your files, and then in that folder, create your new file then it will show options to name it, also you can add a file type extension like .cpp.
TIP: vsc-rename-files extension to rename your files.
I tried to get Eclipse to convert all of the tabs in my project to spaces like this:
Java Editor:
Click Window » Preferences
Expand Java » Code Style
Click Formatter
Click the Edit button
Click the Indentation tab
Under General Settings, set Tab policy to: Spaces only
Click OK ad nauseum to apply the changes.
And now my code is formatted without any indentations within if and for blocks, like this:
private void addAppointment(Resource resource) {
if (resource != null) {
Appt appt1 = new Appt();
appt1.setTime(new Date());
resource.setAppointment(appt1);
}
}
I really don't want to have to manually fix this in the hundreds of files in the project, how can I format to indent within if and for blocks in the whole project?
I should also say that the "Statements within blocks" checkbox in the active Formatter profile is checked. The preview it shows has a for block with an indented body, so I have no idea why that isn't being applied to my project.
#gnac provides some good options, in addition to:
Similarly you can use ctrl+shift+f (Source->Format) on each class to format it on the fly
You can select the project(s) and do Source menu -> Format to format everything in that project in one go. (No keyboard shortcut for it AFAIK.)
So once you set your formatting options you have a couple of options. You can set the preferences to format your files when saving.
Preferences->Java->Editor->Save Actions
However, if you have a lot of files this will be a pain as well. Similarly you can use ctrl+shift+f (Source->Format) on each class to format it on the fly, again having to do it on each file individually.
Inside Eclipse you can use Search->Find, enter "\t" in the text box and select the "Regular Expression" check box and then click the "Replace..." button. When the search is done, it will ask you what to replace it with. Enter 4 spaces into the "With" text field. Click Preview to see what it will do, or OK to make the changes.
I would use a find and sed to find all of the java files in a directory and replace the tabs, although this is outside of eclipse
find -iname ".java" -exec sed -i.orig 's/\t/ /g' {} +
If you're not on Linux you could use cygwin to do the same on Windows.
Whenever I am working in a JSP file and I type ${ to start an el (Expression Language) tag, Eclipse will automatically add } (with a space before the closing brace) after the cursor so that I get ${ } instead of ${}.
Is there a code template in Preferences that I can modify to change this behavior, or is it beyond user preference control?
I have checked in Preferences: Web: JSP Files: Editor: Templates, but none of those templates match. I've also looked in several other sections in Preferences but haven't found anything promising.
What #Mero provided (see comments on answer above) might not be an exact answer, but creating a JSP Template probably the closest thing that I've found.
A few notes for anyone that wants to go that route:
Create a new template through menu Window->Preferences, then in the drill down menu navigate to Web->JSP Files->Editor->Templates. Click New.
Name is a shortcut you can type (the same way typing sysout ctrl+space in Java is a shortcut for System.out.println()). I suggest something simple like el. This allows you to type e l ctrl-space instead of $ { ctrl-space to pull it up.
Context tells it when it should appear in intellisense. I suggest creating two of this template where one has a context of JSP Attribute value and the other has a context of All JSP.
Description is just informative. Put whatever you want. I put 'EL Script' myself.
Pattern is where you put what will be inserted. Put $${${cursor}} or $${${script}}, depending on preference. See below for explanation on the differences.
In Eclipse Templates ${} is how you put variables in the template, so to make it actually print ${} you have to escape the $ with a $$ leading to $${}.
The predefined variable ${cursor} defines where the cursor is after intellisense replaces the el, so to have the cursor appear in between the curly braces you want to do this: $${${cursor}}.
Using any variable that is not predefined (in this case, ${script}) will simply put in that variable with a box around it and allow you to type over it and press enter when you're done, allowing you to move to the end of the closing curly brace.
Note: I understand that this is not an actual answer, but rather is a workaround. I'm putting it here simply so that those who are fine with a workaround can know how to go about doing it.
Edit
For those that don't like having to type ctrl-space, a workaround could be to have the template name start with< since on JSP pages, the < opens the intellisense, so for instance, you could have the name be <el or <$.
A workaround but not an answer:
Disable auto-close of EL tags. You type ${expression} and get ${expression}|, rather than typing ${expression and getting ${expression| }. (| denotes the cursor location)
See this answer, from when this same question was asked of Eclipse Kepler: https://stackoverflow.com/a/20258401/1021426
IN Eclipse i want to chnage the default editor of some .htm files.
If i try to go to FIle Association and assiciate the default editor then file gets opened in that new editor but i don't get the syntax highlighting.
The solution is that the file association is locked ny some plugin editor
Preferences -- Context type----text ----Your editor -- reomve the extension
But i get the .htm(locked) so i cant remove it.
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.user%2Freference%2Fref-content-type.htm
Note: Certain items will be marked as "locked". An item is locked if
it is one of the associations provided by the plug-in that declares
the content type. In other words, you can remove only user-contributed
associations.
Is there any way to remove those locks even thought it can be hackish way but i want to do it
You don't need to "unlock" an existing association to add a new association and make it the default.
Add a new association via the "Add" button
Select the new entry
Hit the "Default" button to make your new entry the default editor
Could it be, that you want to change the "File Association"? This can be done in General / Editors / File Associations. BUT Eclipse uses at least one default-editor and this is the reason for the "locked"-message in the "Content Types". You could set the "Text Editor" to all unwanted types. Looks like a workaround, but makes sense, because it is the same as the file associations of your operating system, that asks you for the program to display the file.
Another question is, why do you want to unlock or remove the "Content Type"? Does it change anything in the Eclipse logic?
Go see this answer from "Greg Desmarais" (assign the desired editor to "default")

I have realized that through eclipse source code there are a lot of comments like this one, I know they are for instructing eclipse that the strings in these lines aren´t supposed to be internationalizable, and I would like if I can place that kind of single line comments using eclipse code completion assistant.
private String toolTip = ""; //$NON-NLS-1$
The Externalize Strings process can take care of that. Select Source → Externalize Strings. Now, select which Strings you wish to externalize. If you wish to Externalize some of the strings, go ahead. Those which will be marked as "Ignore" will automatically get the //$NON-NLS-1$ comment.
You can quickly add these comments by typing nls and clicking Ctrl+Space (code completion, could be different on your platform). There's a template for NLS with a number you need to enter. You can create a template without a number under the Preferences → Java / Editor / Templates.
You can set Eclipse to automatically remove unnecessary $NON-NLS-1$ comments. See under Preferences → Java / Editor / Save Actions → Enable additional actions → Configure → under Unnecessary code.
