SFMono Square - patched font: SFMono + Migu 1M + Nerd Fonts

What's this?

SF Mono is a font from Apple, that is clear, easy to read, and suitable for programming. SFMono Square is based on SF Mono, and added glyphs for Japanese & patched for Nerd Fonts.

How to use

Install with Homebrew.

brew tap delphinus/sfmono-square
brew install sfmono-square

open "$(brew --prefix sfmono-square)/share/fonts"
# open fonts with Finder

Customize

Change the ratio the size for zenkaku / hankaku

In default, this formula reduces the size of glyphs in Migu 1M (zenkaku font) and matches with SF Mono (hankaku font). The ratio is 82%.

When you want to change this value, you can do this by brew edit and follow comments in the formula.

brew edit sfmono-square

See screenshots for examples here.

Troubleshooting

Install failure due to fontforge

==> Installing delphinus/sfmono-square/sfmono-square
Error: An exception occurred within a child process:
  RuntimeError: /usr/local/opt/fontforge not present or broken
Please reinstall fontforge. Sorry :(

The fontforge formula does not link their binaries in default. If you see this, try again after linking it.

brew link fontforge
# again
brew install sfmono-square

VSCode shows “space” glyphs (U+0020) as double width.
