Free Monospace Fonts

General Information

A monospaced (non-proportional) font is a font in which all characters (points of characters) have the same width.

Font comparison

There are several sites that compare programming fonts for the breadth of different characters they cover.

https://mono-math.netlify.app/ - mathematical symbols in monospace fonts.
https://devfonts.gafi.dev/ - fonts for programming.
https://www.programmingfonts.org/ - fonts for programming.
https://coding-fonts.css-tricks.com/ - fonts for programming.

At the moment, the JuliaMono font contains the largest number of mathematical symbols.

Applicability

It is advisable to choose a font for an editor (for example, emacs) with italics. Otherwise, a certain set of text selections is lost.
Also, for semantic italics, various programs with text interfaces are used (for example, the kitty terminal emulator ).
If the font has a variable character width, then tables are used.

Activation of ligature in fonts

LaTeX

When using LuaTeX and XeTeX, ligatures are enabled with the option Contextuals=Alternatepackage fontspec:

\usepackage{fontspec}
\setmonofont{FontName}[Contextuals=Alternate]

Fonts with ligatures

Some programming fonts contain ligatures.

Fira Code

The font is based on Fira Mono.

Iosevka

Site: https://typeof.net/Iosevka/ Repository: https://github.com/be5invis/Iosevka/ Design based on:

PragmataPro,
PF DIN Mono.
The font is pseudo-proportional, so tables designed in this font move apart. (Fixed in version 10).
Has a narrow design.
Properties
- License: SIL Open Font license
- Ligatures: yes
- Italics: yes

Options

For all options, the packages contain three interval options.

Default : Default option with ligatures. Also contains wide (2 column) symbols (such as arrows).
Terminal (Term) : A narrower variant for terminal. Arrows and geometric symbols will be narrow.
Fixed : monospaced font without ligatures and wide glyphs.

Some environments do not treat Iosevka or Iosevka Term as monospace fonts and cannot handle ligatures.

Drawings

Iosevka : Monospace, Default.

LaTeX

Usage in LuaLaTeX and XeLaTeX:

\usepackage{fontspec}

\newfontfamily\JuliaMono{JuliaMono}[
Path=./fonts/,
UprightFont=*-Regular,
BoldFont=*-Bold,
Extension=.ttf]
\newfontface\JuliaMonoRegular{JuliaMono-Regular}
\newfontface\JuliaMonoBold{JuliaMono-Bold}
\setmonofont{JuliaMono-Medium}[
Contextuals=Alternate,
Scale=0.8]

Here the fonts are located in the local directory ./fonts.

Depending on the typeface of the main text for the code, you can use it instead of the typeface JuliaMono-Mediumset JuliaMono-Light.
