Under certain circumjstances Fontforge can not create a font. As the API
does not give any feedback we trudge along afterwards giving confusing
messages.
One example is when the patched font contains too many glyphs.

[why]
In the post we used these information sources to determine the name and
weights/styles of the to-be-patched font:
* The filename
* The fullname (ID 4)
* The postscriptname (ID 6)
Usually it is best to use the Fullname of a font to determine its real
name and styles/weights:
The Postscript name has the advantage to have a hyphen between name and
styles/weight; but as it can not contain blanks the correct name can not
be determined by this. To get the styles/weights back we use a list of
all possible (?!) weights and styles and sort all the string parts.
This works reasonably well and the fullname is usually best.
Not so with Input Mono Condensed. Here are its names:
ID4: "InputMonoCondensed LightIta"
IF6: "InputMonoConsensed-LightItalic"
[how]
Add option to select between fullname and postscriptname as font naming
source.
For special purposes, also allow a custom (arbitrary) name input.
If that is given the specified name will be used to name the patched
font without adding any suffix - the user has full control on the name.

A lot arguments need one user supplied value, but that is not enforced.
For example
font-patcher src/unpatched-fonts/Agave/Agave-Regular.ttf --out
results in a crash, because the needed output directory has not been
passed, but the default is also not used.
The problem is that the option is defined to take any amount of values,
includeing zero values (and more than one value).
That all does not make sense. The switch does need exactly one value.
[how]
Remove the wrong nargs specification. Instead use the default, which is
'expect one value' for the default action 'store'.
Instead of a crash the user is now presented with this output:

Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
Usually the variable `logger` holds the logger object and all logging
calls got through that.
But because we use the font filename as loggername that logger object
can only be set up after the arguments have been parsed. If some
messages are to be logged before the call needs to go to the root logger
called as `logging` class.
This means one needs to take `logger` or `logging` based on the time
when someting is to be logged. That can be confusing and is easily
wrong, especially if code is shifted.
[how]
Always use the `logger` variable and just let that point to the root
logger until we set up a concrete logger.

Codicons: Maximise all circles
[why]
The scaling works okay for `Nerd Font Mono` fonts, but not for `Nerd Font`
fonts. The later have 'unexpected' left side bearing, which looks even
more out of place because the width is unrelated to the advance width
and might place the majority of the glyph into the next cell.
[how]
In fact we do not want scaling and shifting to be uniform for all glyphs
but the intend was to get the scaling from the biggest (full size)
circle and all the smaller ones would be proportionally smaller.
So we add a new Scale grouping that just takes the scale and the
vertical shift of the combined boundingbox, but individually calculates
the horizontal shift.

Patching CartographCF-Bold.ttf creates this naming:

PrefFamily (ID 16) : CartographF Nerd Font

\===> '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 added heavy brackets are maximized within the cell size as all

Furthermore they are all scaled individually, making the size
differences less.
With some proportional fonts the brackets look tiny.
[how]
Introduce new y-padding parameter (because a negative overlap also acts
in x direction, what we do not want (and it distorts)).
Pad the brackets with 30% (15% top and 15% bottom).
This is used for all fonts (monospaced or not) so that the new glyphs
fit nicely with the existing ones. For some definitions of 'nicely', but
that is as good as we can get with automatism. It's not worse than
font-fallback.

When the Heavy Brackets are scaled we want them to be scaled according
to 'pa1!' (i.a. preserve-aspect, only-one-cell, scale-always).
This is not possible because the glyphs have a ScaleRule and that
always assumes pure 'pa' and nothing else.
[how]
When the first glyph of the group is encountered the group scaling is
determined. This now takes the stretch rule of THAT glyph (instead of
just 'pa') to prepare the scale of the complete group.
[why]
With Ubuntu-Regular the fi and fl ligatures are replaced by some font
awesome icons.
The problem is that the font uses the non-standard F001 and F002
codepoints as intermediate referencve to create the actual ligatures
that are at codepoints FB01 to FB04.
[how]
All the normal ligature codepoints (FB00-FB06) are added to the glyph
reference checker and codepoints that are referenced by these are not
patched.
This means that F001 and F002 stay on the original ligatures and the
Font Awesome icons are missing, but this can not be fixed automatically
and would need to 'rewrite' the references inside the font.

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

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 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.

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.

[why]
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.

[why]
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

It does probably not make too much sense to add the box drawing glyphs
to proportional fonts. The boxes that are drawn need to be filled with
some text, and if that does not have monospaced property the box will
always look ugly and not fit and change when the font is changed.
[how]
Make the fact if we detect a source font as monospaced or not a property
of the patcher object.
Always determine that property (before we just determined it when the
target font should have monospaced behavior).
Use that new property to enable/disable the box drawing glyphs.
In a way it is now also prepared to add that as command line parameter
should the need for that arise.

[why]
Normally the 'cell' size should not change on patching. If the 'cell'
size does not change we do not need to rescale the box glyphs. They
probably worked before, they work the same afterwards.
Another reason to disable this is Cascadia Code. It has box drawing
glyphs that extend for more up then the normal cell. If we rescale that
to fit a probably new cell size we get a 'midline' that is too low
(because the upper stems are longer).
[how]
Leave the code in, but disable 'just scale do not copy' mode.

We have 2 different types of metrics warnings. When one warning has been
issued the other is not displayed (if it would trigger). The reason was
that I thought normally there would be no warnings and if someone would
have to inventigate the sourcefont anyhow.
[how]
But the warnings are quite common, so differentiate a bit more when
generating.
Also improve one warning message to make clear what the warning is
about.
And fix the assignment of advance width to width; which has no
consequence because it is never used (at the moment). But it was
obviously wrong.

The greys seem to be too small.
[how]
Separate the blocks into real block, greys and quads. They all have
different scales in Hack which we use to patch in.
If we do not patch in and just scale existing glyphs these three groups
should always be sufficient.
Note that in Hack the quad block 2597 is too small; we could have scaled
it together with the blocks group, but that would raise issues with well
behaved fonts that we just scale and not patch in.

Some few glyphs get a wrong left side bearing in `Nerd Font`:
E0C2: -1230
E0C5: -857
E0C7: -667
E0CA: -1230
These are the powerline glyphs which are right aligned and have overlap
and a target width of 2 cells wide.
[how]
To simplify the code add a new function that decides if a symbol shall
be one or two cells wide.
That function is then used where we had explicit tests already.
Use the function also in the overlap correction code, such that the
overlap is corrected for the right cell occupancy of the concrete glyph.
[note]
I guess that the overlap correction for 'c' alignment for 2 cell wide
glyphs is also broken. But we do not have such glyphs, so we ignore it
for now :-}

[why]
The box drawing glyphs (center aligned) and some Powerline glyphs (that
are right aligned and have a limited xy-ratio) are positioned wrong.
Affected are all box drawing glyphs (e.g. 2548) and some Powerline
glyphs (i.e. E0B2, E0B6, E0C5, E0C7, and E0D4).
[how]
The box drawing glyphs are center aligned and have overlap. The code
does not correct the overlap (left bearing) but uses the default case of
'make the left bearing zero'. The code does just check left aligned
glyphs and not center aligned ones.
Add the correct overlap for center aligned glyphs (i.e. half the
overlap).
The Powerline glyphs are right aligned. Usually that works, because the
glyphs are created with the right size, so that no additional
manipulation is needed.
But if the glyph has a ratio limit the resulting size will be different.
We could in fact fix the size code, somehow, but that is rather
complicated, formula-wise. Instead we just scale these glyphs (which are
the 5 listed above) and shift them to the right position such that the
correct overlap results.

This is more an academic fix. If we calculate widths from with bounding
boxes we always need to take xmin and xmax into account. Usually xmin is
zero and so it does not make any difference.
But maybe one can see better what is calculated, especially as we use
xmin in other cases.

[why]
All the box drawing glyphs should be scaled and shifted as one (i.e.
equally). For such glyph sets we have the ScaleGroups that handle it
nicely, determining a combined bounding box and calculation scale and
shift from that bounding box instead of the actual glyph's bounding box.
But unfortunately it is hard-wired to do just 'pa' scaling. For the box
drawing glyphs we need 'xy' scaling.
[how]
The preparatory stage calculates the 'pa' factor for ScaleGroups for us.
That is mainly so because the old system worked that way and has no
notion of combinded-bounding-box. The data needed to be stored in one
number, the scale. Later came the correct shifting, which needed the
bounding box. But the scaling still relied on the one scale factor that
is used for x and y.
Instead, if we have a combinded bounding box, we ignore the
precalculated scale factor and calculate a new set of x- and y-scales
based on the requested scaling algorithm. In this way we can get 'xy' or
'pa' or even 'xy2' scaling, or whatever we like, based on the combined
bounding box.

For some reason we determine the bounding box xmax value of the 'normal'

unexpected(?) happened.

If a font has references in glyphs that we want to add to the essential

The fontforge function glyph.references returns a three element tuple in
current fontforge (i.e. 20230101). But older versions skip the selection
bit and return only tuples of two.
As we use only the first tuple element we do not care about the 2nd and
possible 3rd element(s) and just thrash them.

All glyphs of the codicons set are individually maximised in size.

Add appropriate ScaleGroups.
For the circles we also include one full-size circle as reference. To

[why]
The Material Design Icons have for sure pairs of glyphs that people
would like to have scaled identically. Because the sheer number of
glyphs and because they are already very nicely and uniformly scaled
within their design space the MDI at the new codepoints where all scaled
the same with taking the theoretical design space as ScaleGlyph.
But that means all icons get scaled a bit smaller than before, where we
individually scaled each Material Design Icon to fill the cell.
This lead to numerous complaints.
[how]
We take a different approach now, more conventional maybe. Especially in
the light that the older bigger icons will get dropped; and people love
them.
So the uniform scaling is ditched and the individual scaling is used.

When a ScaleGroup's combinded bounding box is wider than the target font
cell the actual X position of a glyph in the group depends on it's own
bonding box and not of the combinded bounding box. When doing center
or right alignment.
[how]
'Overwide' ScaleGroup glyphs are correctly placed and shifted in
position, but that would mean a negative left side bearing (i.e. glyph
extends to the left into previous 'cell').
We do not want that and it is later corrected for all glyphs. But that
is done on an individual glyph level and it is just left aligned for its
concrete bounding box (i.e. left side bearing is set to zero).
The dilemma here is that you can not really center a (combinded) glyph
within a cell, when
* the cell is smaller than the glyph
* a left bearing is not allowd
So we change the algorithm here that 'center' and 'right' alignment
mean:
* Center the glyph in the target font cell
* But if that would create a left side 'overhang' (bearing) just left
align (move it as far left as possible without creating a negative
bearing)
The only glyphs affected by this change are the very wide weather icons,
and here escpecially the moon phases F096 and following (target
codepoints E38E ..).

We have an automation for adding glyphs to the original set.
If someone throws in the svg file and adds the glyph to the icons.tsv a
new original-source font is generated.
But the added glyphs are not patched in, because that would need a
change at font-patcher (adjust the end codepoint).
This can be forgotten easily.
[how]
The maximum codepoint of our own (original + seti) set is 0xE6FF. At
0xE700 the Devicons start.
The original-source generation script now checks the offset, they may
not be negative and on the positive end we may not leave our set-range.
If that happens the script fails thus the workflow fails.
Also increate the patch range in font-patcher. If there are no icons to
patch in the symbol font the codepoints are just ignored.
