Wez Furlong 423b208780 font weight can now be specified as the underlying opentype weight ... opentype allows a font to have a weight in the range 0-1000. MacOS has its own concept of symbolic weight names and opentype values that is a slightly different scale of boldness to Windows and Linux. That means that Medium could be a different range of opentype weight values depending on the system. To further complicate things, the font designer can name their variant with any name they like and assign it an arbitrary opentype weight value. For the Operator Mono font, it has Book variant with opentype weight 325 and a Light variant with an opentype weight of 300. wezterm was considering these both to have `FontWeight::Light` because that's how those values were bucketed, which results in amibiguity in resolve the font and frustration in not being able to access one of the variants. This commit changes the `FontWeight` type to now hold the unambiguous opentype weight value, and to define some symbolic aliases for some specified weights. When serializing, if the weight matches a symbolic alias, then that name will be used in the canonical name (eg: as listed via ls-fonts). Otherwise, the numeric value will be used. When parsing the font configuration, wezterm will allow both symbolic and numeric values. This allows all of the Operator Mono variants to be referenced unambiguously, although some variants have to be specified via the numeric weight: ``` wezterm.font("Operator Mono", {weight=275, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-XLight.otf, FontDirs wezterm.font("Operator Mono", {weight="Light", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Light.otf, FontDirs wezterm.font("Operator Mono", {weight=325, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Book.otf, FontDirs wezterm.font("Operator Mono", {weight="DemiLight", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Medium.otf, FontDirs wezterm.font("Operator Mono", {weight="Regular", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Bold.otf, FontDirs ``` https://github.com/wez/wezterm/issues/849#issuecomment-873454483		2021-07-04 08:55:08 -07:00
