Working on Ubuntu 17.04

[jcubic]

on Xubuntu I've installed fonttools:

pip install fonttools

but it keep serving me error:

$ glyphhanger ./index.html --subset=./css/fonts/bebasneue-webfont.ttf
`pyftsubset` from fonttools is required for the --subset feature.

Looking at the source code I've notice that it run which("pyftsubset") and that binary is not provided when Installing form pip you need to run sudo apt install fonttools

and running glyphhanger there is requirement for zopfli

$ glyphhanger ./index.html --subset=./css/fonts/bebasneue-webfont.ttf

Commenting out that option shows another error that brotli is required not optional:

After installing brotli and commentout out cmd.push( "--with-zopfli" ) the program finally run.

Interesting! Is there a better method to check for pyftsubset that would work with pip?

Glyphhanger defaults to using the following: --formats=ttf,woff2,woff-zopfli. You can change this to your liking? Specifically, you can use woff instead of woff-zopfli. Should we change this default?

[patrickkettner]

fwiw, I installed fonttools via pip and it came up with the path without a problem. Is it possible that /usr/local/bin was not in your $PATH, @jcubic ?

[jcubic]

@patrickkettner sorry I don't have Ubuntu anymore, I've switch to Fedora so I can't test but I definitely will install font tools from pip when I'll need to use this project on Fedora.

Installing fonttools resulted in success message in my case, but using glyphhanger resulted in the well known message pyftsubset from fonttools is required for the --subset feature.
I changed into root context using sudo su - and called python3 -m pip install fonttools. This set up everything as needed. On ubuntu 16.04 LTS

@bardware thanks for the clarification! Do you think there’s anything we can do here to clarify or improve our current check for fonttools?

[polarbirke]

Can confirm that @bardware's approach works fine with Ubuntu 18.04 LTS.
