Ah, I see. That's a bit different than I had envisioned. It sounds more like Debian's 'alternatives' framework.
xdg-open and friends choose a program based on filetype detection (for example, mimetype). Ideally, dtopen would use CDE's own action database to open a file, with the same result as if the user had opened the file from within the desktop file manager. Your wrapper (if I now understand correctly) assumes the filetype from user input (eg. which script is run), and then works off its own list. Both of these functionalities are related and useful, yet solve different problems. How about this? dtopen acts as xdg-open and friends by default, but has a flag to force the file type. So, for example: $ dtopen myfile # detect file type, take default CDE action $ dtopen -t video # no detection, open file in a video player $ dtopen -t image # no detection, open file in an image viewer Etc... we could also stick with symlinks over flags if you feel that is better for some reason (or provide both... *shrug*). Maybe CDE already has a script or program to open a file based on the action database, which would make this somewhat redundant. However, that would also make implementation easier, and I think there is value in having this conventional interface. I'd be happy to submit a patch if you like the idea. -mrt Original Message From: Jon Trulson Sent: Thursday, July 19, 2018 21:25 To: cdesktopenv-devel@lists.sourceforge.net Subject: Re: [cdesktopenv-devel] Integration of Antonis Tsolomitis' desktop_approots tarball, with some changes On 07/19/2018 08:15 PM, Matthew R.

At XiG, I called it dthelper, but I didn't like that so I used dtapp for these commit(s). I don't really like that either. :) Right now, dtapp is just a simple shell script that is symlinked to various per-type specific "aliases" - ie: for images it would be dtapp_vimage "filename" to call a list of programs in order to display it (xv, display, etc). I didn't really like "dtapp" and "dtapp_vimage", etc though. I like your idea a lot better. dtopen would be the "base", it's symlinked aliases would be something like dtopen_image, dtopen_video, etc. Yes, I do like that name a lot better. I'll make the change. In the future, we can certainly enhance/replace dtopen if/when we like.
