[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.

[why]
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.

The intend was to drop 'Sans Mono' in the renaming process, because the
name is just too long.

[why]
The license of Bitstream Vera requires patched fonts to contain neither
"Bitstream" nor "Vera" in the name. It explicitly requires that also
for fonts that (only) add some glyphs.
Yes, we are rather late to notice this :-( Sorry.
[how]
Rename Bitstream Vera to BitstromWera, and also drop the Sans Mono part
of the name. The new name looks and sounds similar enough to get the
reference, while being shorter and somewhat logical.

Oblique is not detected correctly anymore.
[how]
With commit
ae656bad8 name-parser: Further formalize style handling
'Oblique' has been taken out of the direct 'known_names' which has been
replaced by a more detailed list of known name parts. It ended up in
known_slopes.
But known_sloped is not taken into consideration as 'weight' when parsing
the font name - no it ends up in 'rest'.
This has been obviously overlooked.

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.

As '(TTF)' is dropped now from Terminus we do not need to handle it
specifically anymore.

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.
[how]
Crossgrade to original Anonymous Pro as source and add the missing
weight/style.
Add Anonymous to SIL.
Handle 'Pro' naming parts (do not detect 'r' as short for 'Regular').

CodeClimate does not allow 'complicated' functions. In a previous commit
we added more if-s to a function that afterwards was rejected by
CodeClimate. To fix that the if-s have been replaced with arithmetic.
That is
a) less readable than if-s
b) has a bug
[how]
Change the code back to if-s but put them into yet another function.
Hopefully we do not blow up CodeClimate's maximum number of functions
per file limit now...

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
present we always take the shortest form of the weight/width.
This is not how it is customarily done.
Experienced:
ExtraCondensed ExtraBold -> ExtCd ExtBd
Expected:
ExtraCondensed ExtraBold -> ExtCond ExtBd
[how]
In case a modifier is present:
Use the shortest form for weights.
Use the longer short form for widths.

Also circumvent CodeClimate issue by replacing if-s with formulas.

[why]
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.

[why]
Some name parts occur in several fonts but they take too much length
that we need to add 'Nerd Font' to the font name.
This can be handled as 'generic' SIL table parts, but the algorithm
stops searching for replacements one it has found one.
[how]
Always evaluate all rules of the SIL table.
Add entries for generics to the SIL table.
Add rule for BigBlueTerminal (437TT).
Also fix rule for MPlus that underwent a naming change with its update.

Cognitive burden of shorten_style_name() is 13 (allowed 9).
Duplicate code
if self.use_short_families[1]:
weights = FontnameTools.short_styles(weights)
styles = FontnameTools.short_styles(styles)

I do not really buy the duplicate code issue (but circumvent it anyway).
shorten_style_name() was really hard to grasp, maybe use of a helper
function makes it more readable.

[why]
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
'invention' (after the paper of the previous commit has been written).
[how]
Separate known weights and make them accessible from other functions.
Use these data tables also for weight detection.
Introduce 'Retina' in the weights table.

[why]
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.

Somehow the `IBM 3270 SemiCondensed` font turn out as

The 3270 font always had the quirk to have a non-standard style with a
dash. We have specific code to circumvent that.

After updating 3270 the 'Narrow' had been renamed to 'Condensed' and so
our specific patch did not work anymore.
Adapt the regex to find the new style that needs correction.

The naming has bizarre blanks strewn in sometimes,
or is all caps. For example
`C a s k a y d i a C o v e` or
`CASKAYDIACOVE-Regular`
[how]
When run under Python2 all strings are unicode strings because
`unicode_literals` is imported by `font-patcher`.
Unfortunately the code checks for type str; but that will all become
type unicode with the import.
One check is suboptimal anyhow and can be dropped, while the other is
turned around.
