Org agenda - alias for file name in weekly view

Question

Some of the org files I use have long filenames (at least longer than 11 characters ;)), this breaks the default weekly view:

elastic-oncall is longer than the space for filename and therefore breaks the format.

Is there a way to specify file name alias, or just make it truncate the filename?

Answer 1

The string that appears in the agenda is, in general, the category to which the entry belongs. But the file name is used as a fallback.

You could then add a category to your whole elastic-oncall with, eg.:

#+CATEGORY: el-onc

at the top of your file.
