node.jsでEmacsからjavascriptを実行するelispを書いてみた。

node.jsの本を読んでいてふとEmacsからnode.jsでjavascriptを実行できたら便利と思いelispを書いてみました。popwin.elが必要です。それとv8-optionをhelmで表示するようにしたのでhelmもあると便利かもしれません。

インストール

el-getを利用していれば以下のコードでel-get-installできると思います。
もし利用していなければ、git cloneでクローンしてロードパスを通してください。

(app-to-list 'el-get-sources
  (:name node-console
         :type git
         :url "https://github.com/yuutayamada/node-console"
         :load-path "./"))

ロードパスを通したら、以下のコードを.emacsなどに設定します。
js2-modeの部分は利用しているjavascript-modeのメジャーモード名に変えてください。
またキーバインドも好きなものに変えてください。

(require 'node-console)
(eval-after-load "js2-mode"
  '(progn
     (define-key js2-mode-map (kbd "C-c C-c") 'node-console)))

利用法

node-consoleコマンド

nodeで-eオプションでコマンドの実行ができるので、Emacsで範囲選択している場合、
その範囲を実行します。
範囲選択していない場合は、そのバッファが.jsで終わる名前かnode-console-javascript-modeで指定したmajar-mode名の場合そのファイルをnodeで実行します。

C-uを押したあとnode-consoleコマンドを実行すると

helmで指定できるv8-optionsを表示します。
node-console-v8-optionsで何かしていれば色が変わります。
アクションを実行するとそのoptionのつけはずしができます。
helmでなんかやってみたかっただけなので、ちょっと微妙です。
optionを見るのにはいいかも。。。

TODO

NODE_ENVとかNODE_PATHとか読み込んだほうがいいのか迷い中。
http://d.hatena.ne.jp/Jxck/20120410/1334071898 このサイト見るとpackage.jsonの
中のscriptに書く場合もあるもよう。
node.jsやjavascriptの習慣に疎いので、よくわからにゃい。。。

google readerからEmacs Newstickerに移行

google readerが7月から使えなくなるそうなので,とりあえずデータの
エクスポートとEmacsのnewstickerで利用できるようにしてみました。

google readerの購読しているサイトのエクスポート

google readerのサイトから,設定(歯車マーク)を選んでから
inport/exportみたいなタブをクリックしてデータをエクスポートします。

Emacsの設定ファイルに書込み

ダウンロードしたデータはunzipコマンドで解凍します。
解凍したファイルの中の
"~/Downloads/your gmail address-takeout/Reader/subscriptions.xml"
のようなxmlファイルからURLのリストを作成します。
次のコードをスクラッチに貼り付けするなどして評価してください。

(defun my/create-url-list (choice file)
  (interactive)
  (let* ((all (xml-parse-file file))
         (body (xml-get-children (car all) 'body))
         (outlines (loop for attr in (cddar body)
                         if (listp attr)
                         collect attr)))
    (loop with dq = (if (eq choice :string)
                        "\\\\\""
                      "\"")
          for atr in outlines
          for title = (replace-regexp-in-string
                       "\"" dq (xml-get-attribute atr 'title))
          for xmlurl = (xml-get-attribute atr 'xmlUrl)
          for htmlurl = (xml-get-attribute atr 'htmlUrl)
          for url = (or xmlurl htmlurl)
          for result = (list title url)
          if (string< "" url)
          collect (case choice
                    (:list result)
                    (:string
                     (concat "(" "\"" title "\"" "\n"
                             "\"" url "\"" ")"))))))

次にあなたのsubscriptions.xmlの置いてあるところに変更して
下のコードを評価してください

(setq newsticker-url-list
      (my/create-url-list :list
    "~/Downloads/YOUR-ADDRESS@gmail.com-takeout/Reader/subscriptions.xml"))

newstickerの起動

newsticker-url-listにURLが反映されたら、
M-x newsticker-treeveiwコマンドを実行すると追加したフィードが反映され
newstickerが起動すると思います。
もし、文字列でほしい場合は下のコードを利用すると文字列を挿入できます。

(defun my/url-insert (pairs)
  (interactive)
  (loop for title-and-url in pairs
        do (insert (concat title-and-url "\n"))))

(my/url-insert
  (my/create-url-list :string "/path/to/subscriptions.xml"))

emacsclientを使い始めました

最近emacsclientを使い出しました。
いい感じに動くようになったのでその時のメモ。

.bashrcや.zshrcに起動用の関数とaliasを登録

-q なしでも最初は動いていたのですが、ある日
"back to top level"というメッセージが表示されつづける不具合が出て
emacsclient難民になっていましたが、ここから 同じ問題になったときは
-q をつけるようにしてeval-bufferを使えというのをみました。
–evalオプションしても同じと思い、自分の設定ファイルを読みこむようにしました。
読み込むファイルはお好みで変えてください。

myemacsclient() {
    local sexp='(load "~/.emacs.d/init")'
    local emacsclient='emacsclient' #24.3.5: emacsclient.emacs-snapshot
    local lang='LANG=ja_JP.UTF-8 '
    local daemon='emacs --reverse --daemon -q' #24.3.5: emacs-snapshot
    if ! pgrep -lf ${daemon} >/dev/null 2>&1; then
        echo "start emacs daemon"
        eval ${lang}${daemon} && ${emacsclient} -n -c --eval ${sexp}
    else
        if [ "$*" != "" ]; then
            ${emacsclient} -n -c $*
        else
            ${emacsclient} -n -c
        fi
    fi
}

alias c="myemacsclient"

使用感

元々Emacsは起ち上げっぱなしがおおかったので、特に便利になったという感じではないのですが一度立ち上げておけば次回の起動はほぼ一瞬なので俺のEmacs超速いと錯覚できます。僕は"C-x C-c"をemacsclient用に少し変更しました。C-x C-cでEmacsを終了するけどdaemonは残す、C-u C-x C-cでEmacsとdaemonも終了するようにしました。

(when (daemonp)
  (defalias 'exit 'save-buffers-kill-emacs)
  (global-set-key (kbd "C-x c") 'suspend-frame)
  (global-set-key (kbd "C-x C-c") '(lambda ()
                                     (interactive)
                                     (if current-prefix-arg
                                         (save-buffers-kill-emacs)
                                       (save-buffers-kill-terminal))))
  ;;emacsclient -cでアクセス時の設定
  (add-hook 'server-visit-hook
            (lambda ()
              (set-terminal-coding-system 'utf-8)
              (set-keyboard-coding-system 'utf-8))))

herokuにNode.jsのアプリを登録

ちょっとNode.jsに興味があってherokuにNode.jsのアプリを登録してみました。
以下は自分の忘れ防止

herokuのアカウントを作成

1. http://api.heroku.com/signup から新規にアカウントを作成
   
2. Email,passwordを選択
   

herokuのtoolbeltをインストール

herokuの toolbelt をインストールするのになんかコマンドがかかれてたのでコピペで実行
そのあと heroku コマンドが利用できるようになった。

sshの鍵の登録

githubやbitbucketで鍵をわけて利用していたので,heroku用に鍵を作成
私はパスフレーズを登録しました。

mkdir -p ~/.ssh/heroku
cd ~/.ssh/heroku
ssh-keygen -t rsa -C "Mail Addless"

それと~/.ssh/configに以下を追加しました。
(IdentityFileは秘密鍵の場所)

Host heroku
  HostName heroku.com
  IdentityFile ~/.ssh/path/to/heroku/secret-key_id_rsa
  User git

heroku

1. heroku loginでアカウント情報を入力
   heroku loginでアカウント情報を入力
   sshの鍵は次で登録するのでNoにしました。
   
   
   
   

   heroku login
   

2. heroku keys:addでheroku用のsshの公開鍵を登録
   
   
   
   

   heroku keys:add file-path(作成したid_rsa.pubのような公開鍵の方のパス)
   

herokuへpushするとき

普通にpushするには

ssh-add heroku's_secret_key
git push heroku master

でいいと思います。そのあと対象のディレクトリで

heroku open

でそのアプリをブラウザで開けました。

Emacsからpush

私はEmacsでmagitからpushしたかったので下記のコードを.emacsなどの設定ファイルに
追加しました。(ssh-agentが動いていることも必要です)

(defun my/ssh-add ()
  (interactive)
  (let* ((github    "~/path/to/github's_id_rsa")
         (bitbucket "~/path/to/bitbucket's_id_rsa")
         (heroku    "~/path/to/heroku's_id_rsa")
         (ssh-add
          (lambda (filepath)
            (unless (string< "" (shell-command-to-string
                                 (concat "ssh-add -l | grep " filepath)))
              (shell-command (concat "ssh-add " filepath)))))
         match)
    (goto-char (point-min))
    (when (search-forward-regexp
           "^Remote:   master @ .* (\\(.*\\))" nil t)
      (setq match (match-string 0))
      (when (string-match "@bitbucket.org" match)
        (funcall ssh-add bitbucket))
      (when (string-match "git@github.com" match)
        (funcall ssh-add github))
      (when (string-match "git@heroku.com" match)
        (funcall ssh-add heroku)))))
(defadvice magit-push
  (around ad-magit-push activate)
  (my/ssh-add)
  ad-do-it)

アプリの/.git/configにbranchの設定を追加しました。
追加後magitでcommitしたところpush待ちのものが見れるようになりました。

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "heroku"]
        url = git@heroku.com:YOUR-APPLICATION-NAME.git
        fetch = +refs/heads/*:refs/remotes/heroku/*
[branch "master"]
        remote = heroku
        merge = refs/heads/master

あとはmagit-statusから"P","P"すればpushしてくれるはずです。
