After skipping the creation of 'Windows Compatible' fonts we have room
to finally add 'Nerd Font Propo' to the release patch sets as first
class citizen.

Also add undocumented feature that environment variable $NERDFONTS can be
used to supply additional or differing options (last option wins).

[why]
Most fonts can run with the full naming (--makegroups 1).
But for some (especially with full fledged subfamilies) the names become
too long. Here we need to select more shortening.
[how]
This can be either done/stored in the font-patcher script, but if you
need shortening (and which) still depends on what set of fonts you want
to patch.
So instead we make it a config.cfg option of the unpatched-fonts.

Some fonts have so long base names that we can not, even very
abbreviated as 'NF', add the Nerd Font designator anymore.
In this case we need to rename the font even if it has no RFN just to
make it shorter.

We use a prepatched font not the original Anonymous Pro.
The prepatched font contains no bitmaps and is thus like
Anonymous Pro Minus. Also some font internals that fontforge does not
copy out of the box are differing.
And we miss the Bold and Italic variants.

Crossgrade to original Anonymous Pro as source and add the missing
weight/style.

CodeClimate does not allow 'complicated' functions. In a previous commit

CodeClimate. To fix that the if-s have been replaced with arithmetic.
That is
a) less readable than if-s
b) has a bug

The shortened name is not as expected "BigBlueTerminal437 Nerd Font"
but some obscure "c7 Nerd Font".
[how]
The backreference marker `\1` is directly in front of the string `437`
which yields the replacement `\1437`. Python is not smart enough to
correctly handle that (but 'sed' for example is).
Instead use a named backreference which does not clash with the
following digits.

When we have a weight/width that can take a modifier, and a modifier is

We want to keep "Nerd Font" in the font name if possible and instead
shorten the weight part with accepted abbreviations. But these abbrevs
are hard to read and sometimes a more mild abbreviating might be
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
changes later on, still.

The name parts of a font are rather restricted in length. Most
systems/applications do not have any problems with long strings, but
some will complain or ignore such fonts.

The old naming is the reason for a lot problems. It creates a lot of

After introducing --makegroups we now enable it for all fonts.
Remove special cases from config.cfg files.
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
The option --makegroups shortens the name suffix and the styles
rigorously. That is needed for fonts with long names and/or long style
descriptions.
But some simple font would not need that. With the option we can adjust
the amount of shortening to fit the specific font (family).
Unfortunately we can not automatically detect that, because the
font-patcher script can not assume anything about a complete family as
every font file is patched individually.
[how]
Add optional numeric parameter to option '--makegroups'.
The values can be:
0 - turned off, use old naming scheme
1 - turned on, shortening 'Bold' to 'Bd'
2 - turned on, shortening 'Nerd Font' to 'NF'
3 - turned on, shortening 'Nerd Font' to 'NF' and 'Bold' to 'Bd'
4 - turned on, no shortening
If --makegroups is not specified this is the same as '--makegroups 0'.
If --makegroups is specified without number that means '--makegroups 3'.
[note]
The argparser module takes the last specified parameter as the one to
use: If you specify --makegroups multiple times only the last one will
be used.
This can be used for gotta-patch-em-all. Per default it (will) specify
--makegroups 3. But via config.cfg we can specify a font centric other
number for individual fonts. The config.cfg values are added later in
the command line, so they take precedence.

[why]
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.
[how]
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
wrong.

Specifying an empty string as prefix unexpectedly does not enable short
family names for all fonts - but for no font at all.
Usually an empty prefix matches all strings (font names).
This makes it hard to enable short families for all fonts no matter
what.

This just drops the 'windows compatibility' options in association with
the name parser (i.e. --makegroups') as we want to always create fonts

not working correctly. But it is easier to do this in smaller steps.

The postscript font name length limit of 31 is only present in very old

Some styles can not take modifiers. We handle the shortening as if they
can. That is not a problem but mighht be unexpected.
Do detect weights we have a fixed list, but that is missing a lot
weights that we would be able to shorten.
The shortening does not work for 'Retina', which is imho a more recent

Separate known weights and make them accessible from other functions.
Use these data tables also for weight detection.

We really struggle to keep the font names below the length limits. To
achieve this some styles are abbreviated. The abbreviations have been
taken from Noto and were initially used to mimic Noto's naming scheme.
But a bit shorter names would help in some instances to produce short
enough name entries. Also some styles that are used by fonts other than
Noto are not abbreviated at all.
[how]
In document [1] Adobe gives examples of very short style abbreviations.
We just implement all these.
Example: 'ExtraCondensed' now becomes 'XCn' instead of the more readable
but longer 'ExtCond' that Noto uses.

[why]
The filenames of the patched fonts are rather ... unique:
- they contain blanks to separate name parts
- they do not separate name and style/weight
This is in part due to history reasons, because the names were not
parsed at all and just some suffix added.
Example (contrived):
Victor Mono Nerd Font Propo Bold.ttf
Normally font file names would be:
VictorMonoNerdFontPropo-Bold.ttf
We ourselves relied in part on that naming scheme, but do not follow it.
There are a lot powerline fonts out there that all add blanks to the
filename.
Some filename recommendation can be found in [1].
[how]
The filename is now always constructed directly from name ID 16
and name ID 17. If one of them is empty ID 1 and ID 2 are used as
fallback, as customary.
ID 16 (ID 1) and ID 17 (ID 2) are separated by a hyphen.
The result is that in can differ from the fontname (ID 6) and uses
always the longest most readable name parts.

Nowadays the Complete font is the normal font. We already dropped the
partially patched fonts long ago. If someone is self patching they will
know if it is a basic font or a complete font.
And already now one can not see if the patched font is bare minimum
(i.e. Seti, Custom, and Devi) or includes Powerline and/or
PowerlineExtra.
[how]
Just drop "Complete" from the naming.
[note]
As the name changes and thus the file name a lot of the other scripts
will break. But they might break anyhow because other naming changes, so
fix that as last commit.

When patching the SymbolsOnly font via gotta-patch-em-all we create a
'Nerd Font Propo'. With the previous change that will be reflected by a
changed name.
The name change can come unexpected for users.
And in fact a 'Nerd Font' version would be ridiculous as there are no
preexsiting glyphs in the font.
So we should keep the previous naming:
* `Symbols Only Nerd Font` (which is in fact a Nerd Font Propo)

- 'normal' (i.e. monospaced oversized symbols): Nerd Font

- 'proportional' (i.e. proportional symbols): Nerd Font Propo
The first two variants have a name, the third one has no name, it is
also called 'Nerd Font' (and it was THE font, for v2.1.0 (only)).

When we crate a font we take the OriginalName, add "Nerd Font" and which
patches we applied, and add "Mono" if --mono has been specified:
OriginalName Nerd Font Complete Mono
OriginalName Nerd Font plus Weather Mono
But the 'Mono' part is quite important, but this scheme will put it in a
place where it is easily out of view or has been removed (to keep the
name short).
This truncation is especially bad on Windows Compatiple and when the
user installs both the 'Nerd Font' and the 'Nerd Font Mono':
SomeVeryLongFontName Nerd Font Complete
SomeVeryLongFontName Nerd Font Complete Mono
become after truncation
SomeVeryLongFontName Nerd Font Comp.ttf
SomeVeryLongFontName Nerd Font Comp.ttf
[how]
Always put the "Mono" directly after "Nerd Font" and all the other name
components come later.

Any non-monospaced font will not be be patched, the patcher crashes.
[how]
This must have happened when the box drawing characters rescaling
feature has been disabled. The default value (False) is not always set.
The box drawing patch has the ability to rescale existing box glyphs.
That used to be done when all box glyphs are already existing in the
source font. We do not patch in a new glyph set then, but we rescale the
existing glyphs to match the possibly new cell size.
But that feature is disabled and the attribute 'dont-copy' is never
utilized. It is disabled because some existing box sets are rather ...
sspecial in their overlap and can not be scaled as we would scale them.

Some old applications seem to depend on obsolete xAvgCharWidth values to
show two-cell glyphs correctly. Fontforge can only generate OS/2 tables
version 4, but these applications need 2 or less. In fact they seem to
not look up the version number, but rely on the value being like it
always has been ;-)
One example is Windows notepad, that takes the xAvgCharWidth as base for
the cell size and draws the two-cell chars in a cell twice that size -
without any regard to glyph width.
[how]
These issue seems to be encountered rather seldom and only with some
obscure (grin) applications. There is also no good way to handle this
automatically. So we add a command line option that allows the user to
tweak the value after patched-font generation.
The option is called `--xavgcharwidth`:
* If not specified the behavior of the patcher does not change
* If just given the xAvgCharWidth is copied over from the source
* If a number is added that number is used as xAvgCharWidth
* If the number added is zero we will calculate the old style xAvgCharWidth
