I have an Eclipse project with special files extension .m4 which are but C files. how can I open them on Eclipse but using C code style just like choosing langage in notepad ++ ?.
If using Eclipse CDT (Eclipse IDE for C/C++ Developers):
In Window > Preferences: C/C++ > File Types click New...
In the C/C++ File Type dialog enter *.m4 as pattern and choose C Source File as type
Click OK and Apply and Close to close both dialogs

I just upgraded to Eclipse 2020-09 (4.17.0) from Eclipse Luna. After installing, I installed Eclipse Web Developer Tools 3.19 from the Marketplace, then restarted Eclipse. When I open a .js file, there is no syntax highlighting. It was fine out of the box with Luna, so is there anything extra that I need to configure in 2020-09? File associations for *.js shows this:
It seems JavaScript files (*.js) have been associated with the plain text editor instead of the Generic Text Editor by mistake (please make sure it has been reported to Eclipse).
Right-click the file and choose Open With > Generic Text Editor.
Or better, associate all *.js files with the Generic Text Editor by right-click a *.js file, choose Open With > Other..., select the Generic Text Editor in the list and tick the Use it for all '.js' files* checkbox at the bottom (as shown in my video here).
Yes, you need to install the Wild Web Developer feature so that it provides that functionality through the Generic Text Editor.
I've installed the plugin for Eclipse Luna: EclipseFP - http://eclipsefp.sf.net/updates . Its Works, but the IDE is not marking the reserved words.
That looks like you are actually using the normal text editor.
Close the file and then right click on the file in Project Explorer and choose 'Open With...' and select the Haskell editor.
Eclipse remembers the last editor you used to open a file so if you had opened this file before installing the plug-in you will get the plain text editor. Once you have opened the file with the correct editor it will use that editor by default in future.
I'm quite new to OSX and I would like to prevent XCode from opening GLSL files in eclipse.
I've tried changing the default program that opens this extension files in the OS, but i can't select eclipse as an option.
Open Eclipse > Preferences > General > Editors > File Associations
Add .glsl files and choose the default editor for this files. Text editor for example.
After a installation of the pdev ( manually cause via "install new software" didn't work ) the normal c/c++ operations have a strange behavior.
e.g.:
c files are not recognised as c files anymore. // no syntax highlighting
an external editor is opening by a double click on a c or c++ file
.
.
.
.
If I remove the files in feuture and plugins all works fine.
Has someone a solution?

First such report I've seen...
Have you tried just adding back the c/c++ file associations at window > preferences > general > editors > file associations?
I have .py and .js files in my Eclipse project for various reasons, but I don't ever want to execute them by double-clicking on them in Eclipse -- which is the default Eclipse behavior.
Is there a way I can change this default behavior so it just opens files in the Eclipse text editor, rather than executes the system "Open" command?
Open the main Preferences window and go to
General->Editors->File Associations
In Eclipse, On the menu bar at the top, go to
Window -> Preferences -> General -> Editors -> File Associations
Set the Open unassociated files with to Text Editor
This opens your files with the Eclipse text editor on double click.
