Idea: Validate XML in .designspace files and maybe presence of source files

[madig]

So instead of passing several UFOs to ufolint, you pass one or more .designspaces files and ufolint validates the XML and then runs all the normal other checks on the source files.

Where is the designspace spec housed?

I think it is specified more or less informally, at https://github.com/fonttools/fonttools/tree/master/Doc/source/designspaceLib.

Thanks!

So this would involve the following?:

1. XML validation check on designspace file
2. parse XML for UFO source paths in sources child element in the following file spec:

<?xml version='1.0' encoding='utf-8'?>
<designspace format="3">
    <axes>
        <!-- define axes here -->
        <axis../>
    </axes>
    <sources>
        <!-- define masters here -->
        <source../>
    </sources>
    <instances>
        <!-- define instances here -->
        <instance../>
    </instances>
    <rules>
        <!-- define rules here -->
        <rule../>
    </rules>
    <lib>
        <dict>
            <!-- store custom data here -->
        </dict>
    </lib>
</designspace>

3. Run tests on each identified UFO source path

What do you mean by 2.? I think checking the XML and then turning it into a designspaceLib.DesignspaceDocument to iterate over the source files is enough. If designspaceLib raises, print that instead and abort.

[chrissimpkins]

Ah sorry, wasn't thinking. Of course we can read it with designspaceLib. Trying to reinvent the wheel.

Something that you'd like to work on? If not, I am willing to add this when time allows.

[madig]

Don't have time this week I think, but we can just leave it here for now...
