### Font Related Configuration

|
|
|
WezTerm bundles [JetBrains Mono](https://www.jetbrains.com/lp/mono/),
|
|
|
|
|
[PowerlineExtraSymbols](https://github.com/ryanoasis/powerline-extra-symbols) and
|
|
|
|
|
[Noto Color Emoji](https://www.google.com/get/noto/help/emoji/) fonts
|
|
|
|
|
and uses those for the default font configuration.

|
|
|
If you wish to use a different font face, then you can use
|
|
|
|
|
the [wezterm.font](lua/wezterm/font.md) function to specify it:
|
2020-04-07 02:32:16 +03:00
|
|
|
|
|
|
|
|
```lua
|
|
|
|
|
local wezterm = require 'wezterm';
|
|
|
|
|
|
|
|
|
|
return {
|
2021-04-10 07:52:25 +03:00
|
|
|
font = wezterm.font("Fira Code"),
|
2020-04-07 02:32:16 +03:00
|
|
|
-- You can specify some parameters to influence the font selection;
|
|
|
|
|
-- for example, this selects a Bold, Italic font variant.
|
2021-04-10 07:52:25 +03:00
|
|
|
font = wezterm.font("JetBrains Mono", {weight="Bold", italic=true})
|
2020-04-07 02:32:16 +03:00
|
|
|
}
|
2020-01-26 23:06:15 +03:00
|
|
|
```

#### Fallback
|
2020-04-07 02:32:16 +03:00

|
|
WezTerm allows specifying an ordered list of fonts; when resolving
|
|
|
|
|
text into glyphs the first font in the list is consulted, and if the
|
|
|
|
|
glyph isn't present in that font, WezTerm proceeds to the next font
|
|
|
|
|
in the fallback list.
|
2020-04-07 02:32:16 +03:00
|
|
|
|
2021-04-10 07:52:25 +03:00
|
|
|
The default fallback includes the popular
|
|
|
|
|
[PowerlineExtraSymbols](https://github.com/ryanoasis/powerline-extra-symbols)
|
|
|
|
|
font, which means that you don't need to use specially patched fonts to use the
|
|
|
|
|
powerline glyphs.
|
2020-04-07 02:32:16 +03:00
|
|
|
|
2021-04-10 07:52:25 +03:00
|
|
|
You can specify your own fallback; that's useful if you've got a killer
|
|
|
|
|
monospace font, but it doesn't have glyphs for the asian script that you
|
|
|
|
|
sometimes work with:
|
2020-04-07 02:32:16 +03:00
|
|
|
|
|
|
|
|
```lua
|
|
|
|
|
local wezterm = require 'wezterm';
|
|
|
|
|
return {
|
2021-04-10 07:52:25 +03:00
|
|
|
font = wezterm.font_with_fallback({
|
|
|
|
|
"Fira Code",
|
|
|
|
|
"DengXian",
|
|
|
|
|
}),
|
2020-04-07 02:32:16 +03:00
|
|
|
}
|
2019-12-30 07:41:08 +03:00
|
|
|
```
|
|
|
|
|
|
2021-04-10 07:52:25 +03:00
|
|
|
WezTerm will still append its default fallback to whatever list you specify,
|
|
|
|
|
so you needn't worry about replicating that list if you set your own fallback.
|
|
|
|
|
|
|
|
|
|
If none of the fonts in the fallback list (including WezTerm's default fallback
|
|
|
|
|
list) contain a given glyph, then wezterm will resolve the system fallback list
|
|
|
|
|
and try those fonts too. If a glyph cannot be resolved, wezterm will render a
|
|
|
|
|
special "Last Resort" glyph as a placeholder. You may notice the placeholder
|
|
|
|
|
appear momentarily and then refresh itself to the system fallback glyph on some
|
|
|
|
|
systems.
