Python scripts

Assortment of scripts that run on the command line, i.e. Terminal on Mac OS X, and Command Prompt on Windows.

Description

buildAll.py

For a given directory, this script goes through every subfolder and runs makeOTF for each font source file (.ufo, .pfa) found.

makeOTF is run with the following options:
-r: release mode
* subroutinization turned on
* strict error-reporting
* GlyphOrderAndAliasDB is applied

-gs: glyphs not listed in the GlyphOrderAndAliasDB are removed from the resulting font file

---

checkAll.py

Run checkOutlines -e to remove overlaps in all source files (.ufo, .pfa) contained in a given directory tree.

-e: This option results in changes to outlines. For a PFA file means that overlapping glyphs will be replaced by new ones (therefore may be lost). In a UFO file, new glyphs are written to a new glyphs.com.adobe.type.processedGlyphs layer, which does not interfere with the foreground, and is used by makeotf to generate font binaries.

---

hintAll.py

Run autohint -q to add hints to all glyphs in in all source files (.ufo, .pfa) contained in a given directory tree.

-q: quiet operation

In a UFO file, hinted glyphs are written to a new glyphs.com.adobe.type.processedGlyphs layer, which does not interfere with the foreground, and is used by makeotf to generate font binaries.

---

generateAllKernFiles.py

For each source file in a given directory tree, generate a kern.fea file, which can be referenced in a features file (as expected by makeOTF).
The kern.fea file contains only raw kern data made of groups and lookups, and must be wrapped in feature tags by way of a include statement.
It may look like this:

feature kern {
    include (kern.fea);
} kern;

It is possible to change settings for generating kern files (such as minimum kerning value, writing of subtables, etc.) directly in the script file.

---

generateOneKernFile.py

Generate a single kern.fea file for a given UFO. The resulting file can be used in the same way as explained above. This script’s options can also be changed as explained above.

---

generateAllMarkFiles.py

For each font source file in a given directory tree, generates mark.fea, markclasses.fea, and mkmk.fea files, which can be used in a features file (as expected by makeOTF).
The m*.fea files contain only raw mark data, and must be wrapped in feature tags by way of an include statement. It may look like this:

include (markclasses.fea);

feature mark {
    include (mark.fea);
} mark;

feature mkmk {
    include (mkmk.fea);
} mkmk;

This script can also create abvm.fea and blwm.fea files for Indic scripts. More information in the script file itself.

---

generateOneMarkFiles.py

Generate mark files (as explained above) for a single UFO.

---

ufo2pfa.py

Convert all UFO files in a given directory tree to PFA (PostScript Type 1) files, using tx.

---

ufo2txt.py

Convert all UFO files in a given directory tree to TXT files, using tx.
TXT files are decrypted PostScript Type 1 (PFA) files.

---

pfa2txt.py

Converts all PFA files in a given directory tree to TXT files, using tx.
TXT files are decrypted PostScript Type 1 (PFA) files.

---

UFOInstanceGenerator.py

(Deprecated workflow, but a great starter for interpolation).
Generate UFO instances from two or more masters, in a one- or two axis MultipleMaster setup. Requires a settings file called instances, the contents of which are better described within the script itself.

---

Installation

Mac OS X: A version of Python is already installed.
Windows: You will need to install one of the 2.x versions available at python.org.

Dependencies

Some of the scripts may require additional Python packages or depend on certain tools being installed and appropriately configured to run on the command line. Here is a list of the locations from which you may need to get the extra tools and packages:

• Adobe Font Development Kit for OpenType (AFDKO)

  • makeotf
  • autohint
  • tx
  • ttx
  • detype1
  • spot

• FontTools

• RoboFab

• Type Supply Tools

  • defcon
  • ufo2fdk
  • woffTools

General usage information

1. Download the ZIP package and unzip it.

• Most of the scripts will run by simply typing python followed by the file name of the script, e.g. python theScript.py.
• If the script is in a different directory from which you are trying to run it, you will need to provide the full path to the script’s file, e.g. python /Users/myself/foldername/theScript.py.
• Some scripts may allow you to use options, or require that you provide input files. To learn how to use those scripts, open them in a text editor app (e.g. TextEdit, Notepad) and read the documentation near the top of the file.
