[BUG] Terminal font detection issue on Alacritty #2070
Description
Read the FAQ first
- I have checked the FAQ but the issue is not covered
Description
When running Fastfetch in Alacritty, the font detection module incorrectly reports the font name as "alacritty" instead of the actual configured font family.
This happens when the Alacritty configuration is in the newer TOML format and uses nested tables for font definition like this:
[font]
size = 12.0
normal = { family = "Maple Mono NL NF CN", style = "Regular" }
bold = { family = "Maple Mono NL NF CN", style = "Bold" }
italic = { family = "Maple Mono NL NF CN", style = "Italic" }
bold_italic = { family = "Maple Mono NL NF CN", style = "Bold Italic" }According to detectAlacritty(), it looks like the current code only queries for top-level keys "family" and "size"
FFpropquery fontQueryToml[] = {
{"family =", &fontName},
{"size =", &fontSize},
};resulting in the fallback being triggered
if(fontName.length == 0)
ffStrbufAppendS(&fontName, "alacritty");The top-level key "family" is not valid in the latest Alacritty configuration whatsoever, and since people can use multiple style-specific fonts at the same time, the parsing logic might be better off handling the entire [font] table and merge the result?
