If I have a family of "Libre Baskerville Condensed" and the detail

this probably means the italic variant of that font. And in fact there
are three instances of that font with three different styles.
And "Monotype Modern Std,Modern MT Std
Condensed:style=Condensed,Regular"
Is it possible that the styles are listed in reverse order?
FontConfig should be deterministic, but I do not believe there is any
attempt at sorting. On my system, consider the output from fc-list: (I
have very few fonts installed)
/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf: DejaVu
Serif:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf: DejaVu Sans
Mono:style=Book
/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: DejaVu Sans:style=Book
/usr/share/fonts/truetype/AlexBrush-Regular.ttf: Alex
Brush:style=Regular
/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf: DejaVu
Sans:style=Bold
/usr/share/fonts/opentype/KaushanScript-Regular.otf: Kaushan
Script:style=Regular
/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf: DejaVu Sans
Mono:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSerif.ttf: DejaVu
Serif:style=Book
The order is consistent from run to run, however it is not sorted by
anything obvious to me. You should probably not rely on anything in the
ordering of entries and/or styles. As such, it would be necessary to
merge the results and sort them for display to the user.
Well, it seems apart from the fact that some font files seem to be
duplicated on my system it seems that many font families are not
reported in one step but in multiple steps that have to be merged
manually.
I'll do some tests and may report back.
I suspect there might be other properties that are there to disambiguate
the results, for instance code page or language support. You could try
running `fc-list : family familylang fontversion` for more details. If
you really want all the details, just use the verbose option: `fc-list
-v`; but be prepared for a LOT of data. ;)
