shebang line for script recognition [message #1289825]

I would like to be able to open a script file in an editor and have Eclipse use the shebang line for file type recognition. Nothing that I've found indicates that this is possible (or that a plugin exists to make it possible Smile

The PyDev plugin documentation SAYS that they do this . . . but it doesn't work, and I haven't seen it documented for any of our other plugins.

Just for info, we are using Windriver Workbench, and therefore Eclipse 3.8.1 plus Eclipse CDT and PyDev

You need to understand that Eclipse's behavior is completely influenced
by the plug-in or set of plug-ins you use. Many plug-ins are not written
by Eclipse.

Have you examined file-type association with editor in Eclipse? This
doesn't not satisfy your shebang requirement, only a plug-in could do
that, but it may be a partial answer.

Last, for birds of a feather, please consider the Eclipse CDT forum and
also whatever forum/mailing list supports PyDev.

Cheers.

Sorry, here is what I was talking about:

Window -> Preferences -> General -> Editors -> File Associations

The issue is that this the File Associations settings don't WORK for files without extensions! So for many scripts, the shebang line is the only source for determining file type.

You should contact the PyDev authors/community for help on this feature, then.

I guess I still haven't been clear; the PyDev plugin was only an example. My point is that if I choose File -> Open on a file with NO extension (certainly common in scripting), then the Eclipse environment should use the shebang line to figure out the file type and the potentially pick the "correct" editor.

My experience has been that this doesn't work at all, and I haven't found anything that implements this behaviour, but maybe I just missed it.

It's certainly common in other editors and IDE's

As Russell explained, only a plug-in can do that--and usually only for the content type it supports. I was under the impression, from you, that PyDev was one of them.

It's a very tricky problem because of how Eclipse identifies files at it's lowest levels. I use ShellEd to edit script files, and here is an open feature request they've had for a long time: http://sourceforge.net/apps/trac/shelled/ticket/4
