[why]
IBM Plex uses some abbreviations also in the fullname and we do not try
abbreviations when resolving weights.
[how]
As this is the only font that has such specials we handle it beforehand
and do not try all combinations of abbreviated and long keywords.
And then their abbreviations are also not standard - at least not used
by us or Adobe, etc.
For such a small amount of affected font files it seems in order to
specifically just fix them instead of a general solution.

The 'Text' weight of Plex is handled as 'other', means that this is
added to the font's name and is a distrinct own family.
But in the original font it is used as weight.
[how]
Remove special handling of 'text' in the font name.
Add 'Text' to known_weights list.
"Text" is not a standard naming, but I see no problems when we handle it
as one. This keeps the family relationships in Blex like Plex.

[how]
Remove not really needed special case.
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
Some fonts might have a non-standard (i.e. broken) weight naming scheme:
They put a blank or a dash between the modifier and the weight, for
example "Extra Bold" or "Demi-Condensed", when they mean "ExtraBold"
resp "DemiCondensed".
The former happens with CartographCF, the later with IBM3270.
[how]
Automatically allow a dash between modifier and weight, which comes up
as CamelCase boundary. Insert an optional dash (r'-?') into such
boundaries.
For the further lookup we need to remove the dash in the found keyword,
if there is any, to get back to standard naming.
This might break if the font name ends in a modifier. So we can not
really distinguish
Font Name Extra Bold Italic
=> Font Name - ExtraBold Italic
=> Font Name Extra - Bold Italic
The known modifiers are 'Demi', 'Ultra', 'Semi', 'Extra'.
It is possible but unlikely that a font name ends in one of these.
For example "Modern Ultra - Bold".
[note]
The question arises if we should not parse the PSname instead of the
Fullname; and stick to the dash there as boundary.
The problem might be prepatched fonts with broken naming, that would be
parsed completely wrong then. So maybe the current approach is still the
best, with the caveat given above (fontnames ending in a modifier).
[note 2]
Funny enough the variable allow_regex_token was not used at all :->
Some leftover? Anyhow we use it now.
[note 3]
We can still not remove the special handling for IBM3270, because the
font initially looks like a PSname and this is parsed as such, which
breaks the name in the incorrect place:
PSname template = "Name-StylesWeights"
Fullname of 3270 = "IBM 3270 Semi-Condensed"

The code is obviously wrong. No effect has been seen, though.
First we check if a certain string is a key in the dict.
If it is, we retrieve the value with the string lower-cased as key.
This does not make sense.
[how]
All the keys are lower case anyhow, so the code seems unneeded. Maybe it
is a leftover. The styles that go into it _and are in the dict_ all come
from a regex-enabled search and thus are lower-cased.
Whatever, to have the correct code we use the lower-cased string for
both, checking for existance and retrieving the value - this is the only
sane approach.
Also change to dict.get() method instead of a self made if code.

Patching CartographCF-Bold.ttf creates this naming:
Family (ID 1) : CartographF Nerd Font Condensed
SubFamily (ID 2) : Bold
Fullname (ID 4) : CartographF Nerd Font Condensed Bold
PSN (ID 6) : CartographFNF-CondensedBold
PrefFamily (ID 16) : CartographF Nerd Font
PrefStyles (ID 17) : Condensed Bold
CartographF Nerd Font Condensed Bold
\===> 'CartographFNerdFont-CondensedBold.ttf'
[how]
The font-patcher historically used the file name of the to-be-patched
font to come up with the new name. When the FontnameParser has been
developed that mechanics has been copied at least for fallback. The
earliest tests compared old and new naming with all the filenames.
Later, when the FontnameParser has been used to really apply name
changes it has always based the parsing on the Fullname or the PSname,
because they really hold the information (or at least should hold);
while the filename might be completely random.
Still code the dealt with specific problems in FILEnames prevailed. The
Ubuntu font for example has a file name like 'Ubuntu-C.ttf', and we
needed to convert the C to Condensed.
As that requirement vanished we can drop all the code that has been
added specifically only for parsing the Ubuntu font filenames.
Side note: USUALLY font filenames should be roughly equal to the PSname.

Because we do not know if a complete family of fonts has an italic face
we must always assume it does. To get clean RIBBI families in ID1/2 we
create a different family for the oblique slant.
But that is not needed if the font does not have an italic slant, but
just an oblique one (like Bitstream Vera and descendants).
[how]
Add new command line option for font-patcher that specifies if the
family of fonts should be patched under the assumption that there might
be an italic face (default), or if we are sure there is none (and we can
leave oblique in the RIBBI group).
This is then applied to the config.cfg files.

It's not nessecary to shorten the PSname so much when no shortening is

noone really cares about the PSname and we can avoid any problems. But

We want to keep "Nerd Font" in the font name if possible and instead
shorten the weight part with accepted abbreviations. But these abbrevs

sufficient to get the desired name length.
[how]
Introduce a new shortening method for the weight parts of a family name.
It takes a longer word (often un-shortened) when a weight stands on its
own, but when a modifier is used together with the weight the more
aggressive two-letter abbreviations are used.
That new shortening method becomes the default and all the functions get
a new parameter to enforce completely aggressive shortening, i.e. always
use the shortest possible form.
The new way to shorten is exposed all the way out to the font-patcher
user who can select the shortening method as parameter to the
--makegroups option. That option is undocumented because I expect some

We created two fonts, one 'normal' and one 'Windows Compatible'. The
later one used shorter names because there are some Microsoft
applications that can not work with long (family-) names.
But it would be better to have universally usable fonts, like all our
sourcefonts. It would reduce confusion and also reduce the size of
installation packages.

ID 1 (Family) family()
Unchanged
Take the short form font name. Appends depending on mode short or long
weight.
ID 2 (SubFamily) subfamily()
Unchanged
Transmogifies Oblique to Italic.
Returns long form styles (i.e. RIBBI)
ID 4 (Fullname) CFF.Fullname fullname()
Take the short form font name (instead of long).
Depending on mode take short or long styles.
This is now in line with ID 4 = ID 1 + ID 2
ID 6 (PS Fullname) CFF.FontName psname()
We limited the length to 31 characters, which is sometimes too short
to have different names for fonts of one same family.
Now we take the short forms of name suffix and styles, for example
VictorMonoNFM-BdIt
ID 16 (Typogr. Family) preferred_family()
The name itself is unchanged (short form name plus verbose suffix),
but the suppression check has been fixed to really compare the
resulting name with the ID 1 name.
ID 17 (Typogr. Subfamily) preferred_styles()
This is unchanged (long form styles) but the suppression check has been
fixed to really compare the resulting string with ID 2.
CFF.Familyname ps_familyname()
Uses ID 16 now and ID 1 as fallback. Was always ID 1 before, which is

Noto are not abbreviated at all.

When the source font is proportional we can not really create a
monospaced (patched) font from it. The glyph width is for example very
small for 'i' but wide for 'W'.
The glyphs are all left aligned, leaving very strange separation between
smallish glyphs.
Even if we would center the glyphs, the look would be strange and
completely differenmt from the source font's look.
[how]
For proportional fonts do not allow to patch with `--mono`.
The fact if a source font is monospaced is determined by examining some
(very few) glyphs. But testing all our source fonts in the repo shows
that it is sufficient.
Furthermore the Panose flag is checked and differences between the flag
and what the glyph examination found are reported.
The user can enforce `Nerd Font Mono` generation with double specifying
the command line option `--mono --mono`. Still a warning will be issued.

Because `gotta-patch-em-all-font-patcher!.sh` does not really count the
variations but calculates them in a separate loop it does not know
anymore how many variations are created per family. The numbers are

Because the information is not needed (in an automated manner) this is
not corrected here.
