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>

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.

Patch from Steve Simpson
|
|
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.
|
|
Allow to use the test elements in the alias element.

The syntax to add any langset to the langset table looks like:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="lang" mode="assign">
<plus>
<name>lang</name>
<langset>
<string>zh-cn</string>
<string>zh-tw</string>
</langset>
</plus>
</edit>
</match>
To remove any langset from the langset table:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="lang" mode="assign">
<minus>
<name>lang</name>
<langset>
<string>ja</string>
</langset>
</minus>
</edit>
</match>

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>
...

This makes creating "same" aliases for renamed font families far easier.
|
|
Fonts.dtd <fontconfig> element was missing the new cachedir element.

The Delicious family includes one named Delicious Heavy, a bold variant
which is unfortunately marked as having normal weight. Because the family
name is 'Delicious', fontconfig accidentally selects this font instead of
the normal weight variant. The fix here rewrites the scanned data by running
the scanned pattern through a new substitution sequence tagged with
<match target=scan>; a sample for the Delicious family is included to
demonstrate how it works (and fix Delicious at the same time).
Also added was a new match predicate -- the 'decorative' predicate which is
automatically detected in fonts by searching style names for key decorative
phrases like SmallCaps, Shadow, Embosed and Antiqua. Suggestions for
additional decorative key words are welcome. This should have little effect
on font matching except when two fonts share the same characteristics except
for this value.

Make cache directories configurable. Simplify and correct some code which
deals with per-directory caches.
|

Add detection of iconv
Document new selectfont elements
Switch to UTF-8 in comment
Add fullname, and family/style/fullname language entries
Respect selectfont/*/glob
Add support for selectfont
Add multi-lingual family/style/fullname support
Expose FcListPatternMatchAny (which selectfont/*/pattern uses)
Add new FcPatternRemove/FcPatternAppend. FcObjectStaticName stores computed
pattern element names which are required to be static.
