starting a MIME application is not reliable #193

Closed muellerto closed 1 year ago

muellerto commented 1 year ago

Describe the bug I have two files with the same extension .xlsx which means Microsoft Excel files. One starts the right MIME application correctly, the other one does not. Look at the situation:

First I tried number 25, everything correct, Excel has been started, I closed it. Then I tried number 46, an error message occurs. This happens also when I write the entire filename on the command line. Why?

Expected behavior The configured MIME application should always be started.

Desktop (please complete the following information):

Hi @muellerto. Two things come to my mind:

  1. Is the file 46 really a spreadsheet file, despite what the extension says?
  2. If it is, maybe the REGEX line for Office documents in the Lira config file is not wide enough to recognize this specific MIME type.

So, please tell me these two things:

  1. Exact MIME type of the file 46: mm info 46 (or using file(1): file --mime-type 46)
  2. The line responsible for office documents in the Lira config file (mm edit). By default it looks like this: X:^application/.*(open|office)document.*=libreoffice;soffice;ooffice
muellerto commented 1 year ago

Ah, I just learned that the extension is not the only criterion for determining a MIME type. I just copied another file into an xlsx file but this has then no MIME type, says mm info.

OK, maybe I was jumping the gun. Currently I make some experiments creating such files by C++ code. Maybe the file I checked was indeed not an ordinary xlsx file. I'll have an eye on this during the next days and then I'll close the case. At the moment all my files work properly, that's why I can't detect any difference using mm info.

leo-arch commented 1 year ago

Great! Please keep me informed.

BTW, you can use file extensions instead of MIME types in Lira too, but it's not that reliable. There are a few examples in the configuration file.

Seems to be a problem with a corrupt file created by myself. Never had that again since then. (But it was cool to blame someone else ...)
