[why] For some fonts with long names the fields are not long enough and for example a 'Mono' can not be seen. [how] Use same field widths as `name_parser_test2`. Signed-off-by: Fini Jastrow <[email protected]>

Lets check all our source fonts: (Skip to next comment for summary) |

Lets examine examples. This is just

[why] 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. [note] 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 wrong. But probably we should count the result font files in the end anyhow. Because the information is not needed (in an automated manner) this is not corrected here. It seems wrong anyhow: total_variation_count=$((total_variation_count+combination_count)) total_count=$((total_count+complete_variations_per_family+combination_count)) Signed-off-by: Fini Jastrow <[email protected]>

Description
If the to-be-patched font is not monospaced, do not allow creation of
Nerd Font Monovariant.Requirements / Checklist
What does this Pull Request (PR) do?
The to-be-patched font is examined if it is monospaced or proportional. This is done by spot checking some glyphs. These are enough to identify proportional fonts in all the fonts we have in
src/unpatched-fonts.Afterwards the information given in Panose is compared, just for informational purposes.
If a user is determined to create a
--monofont the option can be doubled and then the font is patched anyhow(i.e.
--mono --mono).How should this be manually tested?
Any background context you can provide?
What are the relevant tickets (if any)?
