License & Difference from Fira Mono

This work is based on: Mozilla Fira Currently based on commit 5c8d9b.

This work is not based on FiraCode. So Fira Mono Mz doesn't support font ligatures (I personally don't find it useful).

Just like Fira Mono, this work is also free and open source, and the license is the same as Fira Mono.

It changes following chars in Fira Mono:

• &: use the design of & in open source font "Hack"

• @: use the design of @ in open source font "Inconsolata"

• g: slightly modify the shape, to seal the bottom part. This make the g char looks more readable and balanced in small font size.

• Fira Mono Mz:

• Original Fira Mono:

• char g comparison in small font size:
  

• char g comparison in large font size:
  

For font hackers

We have 3 font-forge prject files:

• FiraMonoMz-Bold.sfdir\: font-forge project file for font FiraMonoMz-Bold.
• FiraMonoMz-Medium.sfdir\: font-forge project file for font FiraMonoMz-Medium.
• FiraMonoMz-Regular.sfdir\: font-forge project file for font FiraMonoMz-Regular.

Post-processing to make font be recognized as "Monospaced font"

If you make some changes to the font-forge prject, remember that after exporting your version of .ttf file using font-forge, you need to run following commands:

python fixmono.py FiraMonoMz-Regular.ttf
python fixmono.py FiraMonoMz-Medium.ttf
python fixmono.py FiraMonoMz-Bold.ttf

python fixmono.py FiraMonoMz-ttf-g/FiraMonoMz-Regular-g.ttf
python fixmono.py FiraMonoMz-ttf-g/FiraMonoMz-Medium-g.ttf
python fixmono.py FiraMonoMz-ttf-g/FiraMonoMz-Bold-g.ttf

What is done: the script set the isFixedPitch of each font to 1. (You might need to install fonttools python package first. See fixmono.py for detail.)

why need post-preocessing

See file 0 width glyph.log (which is the output of grep "^Width:" *.glyph > "../0 width glyph.log") for detail: search for keyword 'Width: 0', you can see 27 chars have 0 width.

As a result, the font generated by font-forge will not set the isFixedPitch to 1, which makes some software couldn't recognize the font as Monospaced font.
