Webkitにv8を組み込もうと頑張ってみる

　ビルドはできたんだけどさあどうしようってなったとき、これといって計画はない。そこで何となく組み込みにチャレンジすることにした。

Chromiumにv8の組み込みについて何か情報ないかと探すとこんな文章が

We use the WebKit open-source project to lay out web pages. This code is pulled from Apple and stored in the /third_party/WebKit directory. WebKit consists primarily of "WebCore" which represents the core layout functionality, and "JavaScriptCore" which runs JavaScript. We only run JavaScriptCore for testing purposes, normally we replace it with our high performance V8 engine. We do not actually use the layer that Apple calls "WebKit," which is the embedding API between WebCore and OS X applications such as Safari. We normally refer to the code from Apple generically as "WebKit" for convenience.

まあ、要はWebkit使ってHTMLのレンダリングはしてますよ。元々Webkitに入ってるWebCoreってのを使って。でもJavascriptは我がV8を使ってますよ。元々Webkitに入ってるJavaScriptCoreはテストぐらいにしか使いませんね。
　厳密にいえば、我々は「Webkit」ってものは使ってはいないんですよ。Webkitっていうのはさっき言ったWebCoreっていうレンダリングエンジンとsafariのようなアプリケーションのAPIを組み込んだものなんで。便宜上、Webkitって読んでいるだけなんですよ。

・・・へぇ。

ubuntu 9.04をクリーンインストール

　クリーンインストールしたらflash playerまた入れなきゃならないんだけど。なんせ半年に一回のことなんで忘れちゃって微妙に面倒

1.Adobeのサイトからflash playerのtar.gzファイルをダウンロード
2.ファイルを解凍

tar xvzf ファイル名.tar.gz

3.解凍してできたディレクトリ install_flash_player_*_linuxに入る

cd install_flash_player_*_linux

4.インストール

./flashplayer-installer
//******************
Enterキーを押す
//******************

5.Webブラウザをシャットダウン
6. ホームディレクトリの./mozillaにインストールしますよ。いいですか？と聞かれるので
y を選択。
7.（ここら辺は何書いてあったかあんまり読んでないけど） 他アプリケーションにイントー ルする？って聞かれるのでお好きなように。今回は n を選んだ。

WebKitのビルドに成功

最新版のソースでは無理だったがWebKit-r39474ではすんなり成功した。

所要時間は４０分ぐらい。

./autogen
make

これだけで簡単にビルドはできる。

Googleのコネ？

なぜかこのブログが検索にかかってしまっている。誰も見てないだろうに。Googleのサービス利用してるだけにひいきしてもらってるのだろうか。

何にしても検索かかるのに適当な内容だと申し訳ないので今後はもう少し頑張ってブログ作ることにします。

v8 和訳

『v8　和訳』でググるとこのサイトがトップに表示されて見苦しい。

素晴らしい和訳が
V8ドキュメント日本語訳(ゆとり)
で読むことができます。

トップに検索されてごめんなさい。

悪気はなかったんです。

WebKitビルド少し前進

今までで最も長かったHello World! ~Google v8~

clock_gettime関数が　no reference　ですとg++に怒れつづけて2週間が過ぎた。今日やっとコンパイルに成功した。

g++ -Iinclude hello_world.cpp -o hello_world libv8.a -lpthread -lrt

-lrtがないとlibrtがどうたらこうたら大変らしい。知らないけど。

V8の学習が進展しない

組み込みがなんとも上手くいかない。

何とかならないかな

Google Protocol Buffersについて

いつのまにやら、問題が解決していた。

なんで動くようになったんだろう？謎だ。

Google app engineとGoogle data apiの連携について

取り組み始めて4日目にしてやっとスタートラインに立てた。

ポイントはGAEのローカルテスト環境。

アップグレードしたい場合、ローカルではそれでエラーを出してしまう。＿それ自体がなぜ起きるのかはまだ分からない。＿そのためファイルをアップロードする必要があるらしい。

python if文の扱いについて

a = ""
if a:
print "abc"
else:
print "empty"
>>>empty


a = 1
if a:
print "abc"
else:
print "empty"
abc
>>> a = -1
if a:
print "abc"
else:
print "empty"
abc
>>> a = 0
if a:
print "abc"
else:
print "empty"
empty

文字が入っている場合はTrue。文字が入っていない場合はFalseと判断される。
数字は0はFalse。それ以外はTrueとなる。
最近触ってないから忘れたけどC言語ってこんな感じだった気がする。

GET POST DELETE PUTリクエストをターミナルから送信する

環境：ubuntu 8.10
デフォルトの状態でコマンドを使用できたが環境によっては分からない。
$GET http://gdata.youtube.com/feeds/api/videos?vq=football
#
#footballという単語をyoutubeで検索をかける
#
すごい量のxmlがターミナルに表示される。多分成功したんだと思う。
Google Data Apiを勉強し始めて3日目で初めてすんなり事が運んだ。

BloggerでjQueryを使ってみる

レイアウトからwidgetの編集してしまえばさほど難しくない、Google data apiとの連携ができないだろうか

<script src='http://www.google.com/jsapi' type='text/javascript'/>
<script type='text/javascript'>//<![CDATA[
google.load("jquery", "1");

google.setOnLoadCallback(function(){
$("#btn").click(function(){
alert("TEST Click");
});
});
//]]>
</script>
