The type will be resolved at runtime...
For example, we can do this now without getting a warning:
<match target="font">
<test name="scalable" compare="eq">
<bool>false</bool>
</test>
<edit name="pixelsizefixupfactor" mode="assign">
<divide>
<name target="pattern">pixelsize</name>
<name target="font" >pixelsize</name>
</divide>
</edit>
<edit name="matrix" mode="assign">
<times>
<name>matrix</name>
<matrix>
<name>pixelsizefixupfactor</name> <double>0</double>
<double>0</double> <name>pixelsizefixupfactor</name>
</matrix>
</times>
</edit>
<edit name="size" mode="assign">
<divide>
<name>size</name>
<name>pixelsizefixupfactor</name>
</divide>
</edit>
</match>
Previously the last edit was generating:
Fontconfig warning: "/home/behdad/.local/etc/fonts/conf.d/00-scale-bitmap-fonts.conf", line 29: saw unknown, expected number
Based on idea from Raimund Steger.
For example, one can do something like this:
<match target="font">
<test name="scalable" compare="eq">
<bool>false</bool>
</test>
<edit name="pixelsizefixupfactor" mode="assign">
<divide>
<name target="pattern">pixelsize</name>
<name target="font" >pixelsize</name>
</divide>
</edit>
<edit name="matrix" mode="assign">
<times>
<name>matrix</name>
<matrix>
<name>pixelsizefixupfactor</name> <double>0</double>
<double>0</double> <name>pixelsizefixupfactor</name>
</matrix>
</times>
</edit>
</match>
Part of work to make bitmap font scaling possible. See thread
discussion:

Previously a <matrix> element could only accept four <double> literals.
It now accepts full expressions, which can in turn poke into the
pattern, do math, etc.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 8: reading configurations from ~/.fonts.conf.d is deprecated.
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
Be polite and do not issue the warning if deprecated config includes
(e.g. ~/.fonts.conf.d and/or ~/.fonts.conf) do not exist.
Warn if the multiple values is set to <test>, including the case of
in <alias> because the behavior isn't intuitive since so many users
is asking for a help to get things working for their expectation.
Use multiple <match>s or <alias>es for OR operator and
multiple <test>s for AND operator.
Allows reading configuration files, fonts and cache files from
the directories where the XDG Base Directory Specification defines.
the old directories are still in the configuration files for
the backward compatibility.
Add a new attribute `ignore-blanks' to <test>.
When this is set to "true", any blanks in the string will be ignored
on comparison. This takes effects for compare="eq" or "not_eq" only.
Also changed the behavior of the comparison on <alias> too.
The syntax to add any characters to the charset table looks like:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<plus>
<name>charset</name>
<charset>
<int>0x3220</int> <!-- PARENTHESIZED IDEOGRAPH ONE -->
</charset>
</plus>
</edit>
</match>
To remove any characters from the charset table:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<minus>
<name>charset</name>
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</charset>
</minus>
</edit>
</match>
You could also use the range element for convenience:
...
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<range>
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</range>
</charset>
...
The East Asian double-byte codepages have characters with backslash as
the second byte, so we must use _mbsrchr() instead of strrchr() when
looking at pathnames in the system codepage.
Must not call FcStrFree() on a value returned by
FcStrBufDoneStatic(). In the Windows code don't bother with dynamic
allocation, just use a local buffer.
