jQuery-uiのautocompleteで遊んでみる

ajaxでjsonpをあらかじめ取得しておき、autocompleteにわたすサンプル

jspで取得する値はmemcachedに入っている

jQueryのsuggestとautocompleteを使ってみる

投稿者: utsubo 投稿日: 2013-02-15 in jQuery

googleなどの検索ボックスで予測したり、ぺろっと出てくるあれ、実装してみました

予測で出てくるあれ

こちらからjquery.suggest.jsをゲット

ぺろっとでてくるあれ

こちらからjquery-1.9.0.jsとjquery-ui.jsをダウンロード

GSONを使ってJson文字列をパースする

投稿者: utsubo 投稿日: 2013-02-12 in java

ＪＳＯＮの文字列を簡単にＪＡＶＡのクラスにしてくれます

gson-2.2.2.jar
java version “1.6.0_37”
iOS10.8.2

package jp.qri.search;

import java.util.List;

import com.google.gson.Gson;

public class GsonTest {
	public static class StockItem{
		public String string;
		public String code;
		public String toString(){
			return "("+string+":"+code+")";
		}
	}
	public static class StockList{
		public List<StockItem> stocks;	// 配列はListを使う
		public StockList(){}
		public String toString(){
			String ret="";
			for(StockItem item:stocks){
				ret+=item.toString()+",";
			}
			return ret;
		}
	}
	
	
	public static void main(String[] argv){
		Gson gson=new Gson();
		String jsonStr="{\"string\":\"ソニー\",\"code\":\"6758\"}";
		StockItem item=gson.fromJson(jsonStr,StockItem.class);
		System.out.println(item.toString());
		
		String jsonString="{\"stocks\":[{\"string\":\"ソニー\",\"code\":\"6758\"},{\"string\":\"ソニーフィナンシャルホールディングス\",\"code\":\"8729\"}]}";
		StockList list=gson.fromJson(jsonString, StockList.class);
		System.out.println(list.toString());
	}
}

package jp.qri.search;

return ret;

}

public static void main(String[] argv){

StockItem item=gson.fromJson(jsonStr,StockItem.class);

System.out.println(item.toString());

ruby-mysqlで文字コード指定

投稿者: utsubo 投稿日: 2013-02-07 in mysql、ruby

rubyでMYSQLにつなぐ際にMySQL/Rubyを使っていたのですが、どうやら開発が止まってしまったらしくruby1.9には非対応とのこと

https://github.com/tmtm/ruby-mysql

こちらからruby-mysqlなるものをダウンロード。

ちなみにプロキシ越しのgemではうまくいきませんでした

# gem install ruby-mysql
WARNING:	Error fetching data: too many connection resets (http://rubygems.org/latest_specs.4.8.gz)
ERROR:	Could not find a valid gem 'ruby-mysql' (&gt;= 0) in any repository
ERROR:	Possible alternatives: ruby-mysql

# gem install ruby-mysql

WARNING: Error fetching data: too many connection resets (http://rubygems.org/latest_specs.4.8.gz)

ERROR: Could not find a valid gem 'ruby-mysql' (>= 0) in any repository

ERROR: Possible alternatives: ruby-mysql

とりあえずインストール

# ruby setup.rb

1	# ruby setup.rb

日本語

mysqlにはSjisでデータが入っており、クライアントがutf-8の場合には以下のように書く必要があります

#/bin/env ruby -w -Ku
# -*- coding=utf-8 -*-
client=Mysql.connect("localhost","root","pass","dbname")
client.charset="utf8"
res=client.query("select id,name from IdTable")
res.each{|r|
p r
}

#/bin/env ruby -w -Ku

# -*- coding=utf-8 -*-

client=Mysql.connect("localhost","root","pass","dbname")

client.charset="utf8"

res=client.query("select id,name from IdTable")

res.each{|r|

p r

}

memcachedで日本語キーを扱う

投稿者: utsubo 投稿日: 2013-02-04 in mac、memcached、ruby

kyoto tycoonはmemcachedと同じインターフェースで起動できるとのことで、当然memcachedライブラリが使えます

なんかだめ。。

ちなみにperlだと

#!/usr/bin/perl

use strict;
use warnings;
use Cache::Memcached::Fast;

my $memd=Cache::Memcached::Fast->new({
		servers => [ { address => 'localhost:11211' }], 
}); 

# 値を追加 key => value
my $key='ソニーal';
$memd->set($key=> 'そにー2');

# 値を取得
my $id = $memd->get($key);
print "$id\n";

#!/usr/bin/perl

use strict;

use warnings;

use Cache::Memcached::Fast;

my $memd=Cache::Memcached::Fast->new({

servers => [ { address => 'localhost:11211' }],

});

# 値を追加 key => value

my $key='ソニーal';

$memd->set($key=> 'そにー2');

# 値を取得

my $id = $memd->get($key);

print "$id\n";

$ perl mem.pl
そにー2

1 2	$ perl mem.pl そにー2

rubyのライブラリが悪いようだ

vimのシンタックスハイライトにscalaを追加する

投稿者: utsubo 投稿日: 2013-01-01 in mac

macでscalaを使うためにはbrewでインストールするのが一番簡単です

brew install scala

1	brew install scala

このままだとvimで.scalaを開いた際に色がつかないので非常にみづらいです

いろいろやり方はあるみたいですがこれが一番簡単でした

mkdir -p ~/.vim/{ftdetect,indent,syntax} &amp;&amp; for d in ftdetect indent syntax ; do wget --no-check-certificate -O ~/.vim/$d/scala.vim https://raw.github.com/scala/scala-dist/master/tool-support/src/vim/$d/scala.vim; done

1	mkdir -p ~/.vim/{ftdetect,indent,syntax} && for d in ftdetect indent syntax ; do wget --no-check-certificate -O ~/.vim/$d/scala.vim https://raw.github.com/scala/scala-dist/master/tool-support/src/vim/$d/scala.vim; done

KeyChain

投稿者: utsubo 投稿日: 2012-12-06 in iOS

iPhoneではパスワードなどを保存する際にはKeyChainなるものを使って厳密に保存する必要があるとのことです。SQLiteなどに保存するのはもってのほかとか。。

この辺りを参考にコーディング。

見よう見まねなのでよくわかっていなかったのですが、”v_Data”や”acct”は固定値だったのですね。勝手に追加しようとしたらおこられました
