Hi,

I've been looking at

https://bugs.eclipse.org/bugs/show_bug.cgi?id=97811#c4
https://bugs.eclipse.org/bugs/show_bug.cgi?id=88370
and some other editor lookup related bugs.

Is it still true that a plugin is not capable of changing the default
editor for e.g. more specific xml files ?

Registring a xml content-type and a editor for that specific content type
does not result in the editor
being chosen as the default editor? Furthermore it does not show up on the
Open with... list unless the file name
is a complete match (registring the editor for just *.xml is not an option
as it does not make sense to use it for all
*.xml files)

With hope that someone knows about how plugins should be able to "win"
over the generic platform provided editors ;)

Yes you can use content type. The Ant build editor does just that. Look
up IContentDescriber. As an example see the
org.eclipse.ant.internal.core.contentDescriber.AntBuildfileC ontentDescriber
as an example, except that you will need to do your own super class
implementation because AntBuildfileContentDescriber inherits from an
internal class.

The IContentDescriber reads a file to determine if the content is of
interest to the type it is looking for. For example the
AntBuildfileContentDescriber sees if the xml file starts with a
"project" element and has a "target" element in it.

A content type can be a subtype of another content type, so for example
the AntBuild content type is a subtype of XML content type, so it
doesn't need to try to determine if it is an XML type, that is already
been determined.

You will need to update your plugin.xml to add your content type
describer and to have your editor use your content type.

Look up the ContentDescriber extension point in the help.

I figured out why it selected a different editor than i expected it.

The id of a content-type is a short name where as the content-type id in
the editor association
is <pluginid>+<content-type>...when I fixed that stuff started to work ;)
