Akira TAGOH a563a1802e Add new element remap-dir instead of extending dir element 2019-04-03 12:02:09 +00:00
Keith Packard c4324f54ee Replace UUID file mechanism with per-directory 'map' attribute [v2]
The UUID files would be placed in each font directory to provide the
unique cache name, independent of path, for that directory. The UUID
files are undesireable for a couple of reasons:

 1) They must be placed in the font directories to be useful. This
    requires modifying the font directories themselves, introducing
    potential visible timestamp changes when running multiple
    applications, and makes the cache processing inconsistent between
    applications with permission to write to the font directories and
    applications without such permission.

 2) The UUID contents were generated randomly, which makes the font
    cache not reproducible across multiple runs.

One proposed fix for 2) is to make the UUID dependent on the font
directory path, but once we do that, we can simply use the font
directory path itself as the key as the original MD5-based font cache
naming mechanism did.

The goal of the UUID file mechanism was to fix startup time of
flatpaks; as the font path names inside the flatpak did not match the
font path names in the base system, the font cache would need to be
reconstructed the first time the flatpak was launched.

The new mechanism for doing this is to allow each '<dir>' element in
the configuration include a 'map' attribute. When looking for a cache
file for a particular directory, if the directory name starts with the
contents of the <dir> element, that portion of the name will be
replaced with the value of the 'map' attribute.

Outside of the flatpak, nothing need change -- fontconfig will build
cache files using real directory names.

Inside the flatpak, the custom fonts.conf file will now include
mappings such as this:

	<dir map="/usr/share/fonts">/run/host/fonts</dir>

When scanning the directory /run/host/fonts/ttf, fontconfig will
use the name /usr/share/fonts/ttf as the source for building the cache
file name.

The existing FC_FILE replacement code used for the UUID-based
implementation continues to correctly adapt font path names seen by
applications.

v2:
	Leave FcDirCacheCreateUUID stub around to avoid removing
	public API function.

	Document 'map' attribute of <dir> element in
	fontconfig-user.sgml

Akira TAGOH 20191810d1 Bug 23757 - Add mode="delete" to <edit>
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.

Akira TAGOH d26fb23c41 Bug 59385 - Do the right thing for intermixed edit and test elements
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>

Behdad Esfahbod 51b0044648 Allow target="font/pattern/default" in <name> elements
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>

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.

Akira TAGOH bc4517d8e5 Bug 19128 - Handling whitespace in aliases
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.

Akira TAGOH 3c862aad9f Add editing langset feature.
The syntax to add any langset to the langset table looks like:

<match target="scan">

    </test>
    <edit name="lang" mode="assign">
        <plus>

To remove any langset from the langset table:

    </test>
    <edit name="lang" mode="assign">

Akira TAGOH 857b7efe1e Add charset editing feature.
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>
...

Keith Packard c2c6976d1a Add FcMatchScan to resolve Delicious font matching issues (bug #6769)
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.
