Font renaming script for OpenType tables in CFF (.otf) and OT TrueType (.ttf) fonts

fontname.py's Introduction

fontname.py

About

fontname.py is a .ttf and .otf font renaming script that is developed in Python. It supports font renaming with the Python 3.6+ interpreter.

Dependency

fonttools Python library (requires v4.0.0+)

Install with:

pip3 install fonttools

Usage

The script usage is as follows:

$ python3 fontname.py [NEW FONT FAMILY NAME] [FONT PATH 1] <FONT PATH ...>

This script updates the OpenType name table records nameID 1, 4, 6, and 16 with appropriately formatted font names using the font style definition in the font and the new font family name defined by the user as the first command line argument. The CFF fontName, familyName, and fullName fields are edited in CFF fonts (*.otf). You can include any number of subsequent font paths on the command line. The style will be detected in the OpenType tables of the fonts filepath arguments and will be used to create new name strings in the OpenType tables.

Note: this re-writes the name tables in the fonts passed as arguments on the command line (i.e. writes files in place) so make copies first if you intend to maintain the fonts with the former naming for any reason (though you can simply re-write with the previous name if you forget...).

Examples

$ python3 fontname.py "Hack DEV" Hack-Regular.ttf

$ python3 fontname.py "Source Code Pro DEV" SourceCodePro-Regular.otf

$ python3 fontname.py "DejaVu Sans Mono DEV" DejaVuSansMono-Bold.ttf

These should all be detected as "different" fonts so that you can install them side-by-side with the pre-modified versions.

fontname.py's Issues

FullName in CFF table is not changed

I recently used your script and it works fatastic, however I realised, that the FullName in CFF table is not changed.
I had no problems whatsoever so far with renamed fonts, yet I’m still wondering what this entry in the CFF table does.
So far all apps I tested the fonts with don't seem to care about this entry. Is it not important? Do I not need to change it?
For the sake of consistency I changed it manually with ttx, but I was wondering if there is a better way/it is necessary.

Name ID 3 also needs to be changed (unique identifier)

The unique identifier also needs to be changed. Adding this to the code fixes it (line 94):

 elif record.nameID == 3:
       record.string = nameID6_string

The issue made a font unusable by some applications.
Hope it helps!

Error: Unable to detect the font style

Running this on some TTF files gives the following error:

[fontname.py] Unable to detect the font style from the OpenType name table in '[FONT-NAME].ttf'. 
Unable to complete execution of the script.

Does this mean my TTF files are corrupt or missing something or is this actually a bug? Wondering if I need to use TTX to do the recompile to get the name to change or if there's some changes I might be able to make to fontname.py to fix the issue.

Thanks, and thanks for this cool repo!

Unicode decode error with checkmark (U+2713) glyph in print statement

Observed by @texhex on Windows platform.

"can't find 'main' module"

Running this:

$ python /Users/[obfuscated]/Code/github/chrissimpkins/fontname.py "Hack DEV" Hack-Regular.ttf

produces this error:

/Users/[obfuscated]/.asdf/installs/python/3.6.2/bin/python3.6: 
can't find '__main__' module in 
'/Users/[obfuscated]/Code/github/chrissimpkins/fontname.py'

Any ideas?

Location of the files

Hello,
The fontmake.py files should always be stored in the folder where the font files are or there is a way to install "globally" on a computer?

Thanks,
Maciej

Support for localized names

Many CJK fonts have localized names, do we support modifying them now?

e.g.

{
en: "Source Han Sans SC"
}, {
 zh: "思源黑体"
}

Not renaming font family on MacOS

Reproduce steps:

Download FontAwesome for web
Run:

python fontname.py "TEST" /Users/ryan/Downloads/fontawesome-free-5.8.1-web/webfonts/fa-solid-900.ttf

[OK] Updated '/Users/ryan/Downloads/fontawesome-free-5.8.1-web/webfonts/fa-solid-900.ttf' with the name 'TEST Solid'

Open fa-solid-900.ttf with Font Book app (or another app that displays .ttf font family)
Note that font family is still Font Awesome 5 free

I wrote a blog post where this used to work (at least on 12/27/2018). I can't figure out what has changed.
