This feature requires the FreeType 2.5.1 or later at the build time.
Besides <range> element allows <double> elements with this changes.
This may breaks the cache but not bumping in this change sets at this moment.
please be aware if you want to try it and run fc-cache before/after to
avoid the weird thing against it.
This change reverts 9acc14c34a
because it doesn't work as expected when building
with -fshort-enums which is default for older arms ABIs
Thanks for pointing this out, Thomas Klausner, Valery Ushakov, and Martin Husemann
Add two edit mode, "delete" and "delete_all".
what values are being deleted depends on <test> as documented.
if the target object is same to what is tested, matching value there
will be deleted. otherwise all of values in the object will be deleted.
so this would means both edit mode will not take any expressions.
e.g.
Given that the testing is always true here, the following rules:
<match>
<test name="foo" compare="eq">
<string>bar</string>
</test>
<edit name="foo" mode="delete"/>
</match>
will removes "bar" string from "foo" object. and:
<match>
<test name="foo" compare="eq">
<string>foo</string>
</test>
<edit name="bar" mode="delete"/>
</match>
will removes all of values in "bar" object.
This changes allows to have multiple mathcing rules in one <match> block
in the same order.
After this changes, the following thing will works as two matching rules:
<match>
<!-- rule 1 -->
<test name="family" compare="eq">
<string>foo</string>
</test>
<edit name="foo" mode="append">
<string>foo</string>
</edit>
<!-- rule 2 -->
<test name="foo" compare="eq">
<string>foo</string>
</test>
<edit name="foo" mode="append">
<string>bar</string>
</edit>
</match>
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

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>
...
