Demo: rendering PostScript on Hieroglyph

It's been a while to post something on this blog. and I'm demonstrating this second times, but with the different code-base.
I don't have too much words to talk about this yet; This is too simple and too slow, plus may be too bored to have a look. but it should be a big step toward seeing what Hieroglyph is. anyway here is a demo video:



Note: just uploaded the original ogg video file here.

A hack to allow editing the charset and the lang in a font on fontconfig

Background

fontconfig is scanning a font and gathering the information to see what kind of character sets it's possible to support. being used to pick up the certain font according to  a request from a user. having said that all of the fonts doesn't necessarily have certain coverage of the glyphs for certain character sets. so given that missing glyphs are not a big deal or still looks good with a fallback font for them, there should be needs to use such fonts for the certain language anyway.

Syntax

After this hack, two elements are available. <charset> to update the character sets information a.k.a. FcCharSet and <langset> to update the language coverage information a.k.a. FcLangSet. in either case, the element has to have the language name that is available as orth file in fontconfig but without .orth suffix, as CDATA. it looks like:

<match target="scan">
                <test name="family">
                        <string>HanaMin</string>
                </test>
                <edit name="charset" mode="assign" binding="strong">
                        <charset>ja</charset>
                </edit>
                <edit name="lang" mode="assign" binding="strong">
                        <langset>ja</langset>
                </edit>
        </match>

And you have to run fc-cache again to re-generate the fontconfig cache file because the above rule only affects the scan phase. then starting to match HanaMin for serif:lang=ja in this case. which originally has zh-hk, zh-mo and zh-tw coverage.

How to reset the background on GNOME desktop (with unusual way...)

ニッチな需要かもだけど、どうなってんのという感じで。

背景画像や背景色の変更はGNOME上ではgnome-appearance-propertiesで行う。ここを一度でも変えると個々人の設定として記録される。ディストリビューションによっては毎リリースごとテーマを変えてくるものもあり、新しいバージョン入れた!って気分を味わえなくてつまらないので、これを強制的にリセットする方法を探してみた。

といってもそんな大した話ではないけど、まずひとつ。/desktop/gnome/background/picture_filenameというキーがあって、こいつをクリアすると背景画像がデフォルトのものに戻る。が、しかし、再びgnome-appearance-propertiesを起動すると設定したものへまた戻ってしまう。
で、もうひとつ。$HOME/.gnome2/backgrounds.xmlというファイル。ここにも背景画像、背景色に関する情報が記録される。両方消すとデフォルトのものが正しく適用されるようになる。

おしまい。

Fedora yum repository for Mozc available

I've just created yum repository metadata for Mozc on my fedorapeople space. you can install the latest package after installing mozc.repo file under /etc/yum.repo.d on your system.


Currently it contains the binary rpms for i686 and x86_64 only on Fedora 12 and 13. but not for ppc nor ppc64 because unfortunately the build failed.

For another news,  started to include mozc-config in the package. though I pondered to make another package for that, it was difficult to do so because it requires the build environment of Mozc for header files and static libraries and objects.

Enjoy,

[Update: 2010/05/28]: fixed a fail on i386 box to fetch the metadata via yum; sorry for inconvenience.
[Update: 2010/06/22]: fixed the repo file and URL because it has been changed due to the restructure of the package.
