●概要
Furukawa Toru氏が作成したpy-modeにいくつかの機能(shift-regionなど)
を追加してみたものをFurukawa氏のサイトで公開してもらっていましたが、
このたび本格的にTim Peters, Barry Warsawらによるemacs用Python-mode.elの
移植にチャレンジしてみました。作成に当たっては以下のソフトウェアを参考に
しました。
python-mode.el by Tim Peters
py-mode.l by Toru Furukawa氏
emacs.l by manabu@chaos.club.ne.jp
shell3.l by Hattori Masashi
comint.el
●注意事項
pdb関係、Jython関連はまだ移植が終わっていません。
時間があればチャレンジしてみたいと思います。
●インストール
0. netinstallerを利用した場合は特に設定は必要ありません。
　　　動作に不満がある場合はこのソースの設定用変数部分を参照してください
1. py-mode.lをsite-lispフォルダにコピー。
2. バイトコンパイル(byte-compile-file)して、.xyzzyかsite-init.lに
(load-library "py-mode")
(push '("\\.py$" . py-mode) *auto-mode-alist*)
と書いて、必要に応じてダンプし直せば大丈夫です。
x. 文字コードについて
PYTHONPATH\Lib\site-packages\sitecustomize.py(なければ作る)に
import sys
from codecs import getwriter
sys.setdefaultencoding('shift_jis')
sys.stdout = getwriter('shift_jis')(sys.stdout)
と書くと日本語のエンコード関係がマシになるかもしれません。
●使い方
M-x py-mode バッファをpy-modeにする
C-c m (py-describe-mode) py-modeの日本語ヘルプ

"Start an interactive Python interpreter in another window.
This is like Shell mode, except that Python is running in the window
instead of a shell. See the `Interactive Shell' and `Shell Mode'
sections of the Emacs manual for details, especially for the key
bindings active in the `*Python*' buffer.
With optional \\[universal-argument], the user is prompted for the
flags to pass to the Python interpreter. This has no effect when this
command is used to switch to an existing process, only when a new
process is started. If you use this, you will probably want to ensure
that the current arguments are retained (they will be included in the
prompt). This argument is ignored when this function is called
programmatically, or when running in Emacs 19.34 or older.
Note: You can toggle between using the CPython interpreter and the
JPython interpreter by hitting \\[py-toggle-shells]. This toggles
buffer local variables which control whether all your subshell
interactions happen to the `*JPython*' or `*Python*' buffers (the
latter is the name used for the CPython buffer).
Warning: Don't use an interactive Python if you change sys.ps1 or
sys.ps2 from their default values, or if you're running code that
prints `>>> ' or `... ' at the start of a line. `python-mode' can't
distinguish your output from Python's output, and assumes that `>>> '
at the start of a line is a prompt from Python. Similarly, the Emacs
Shell mode code assumes that both `>>> ' and `... ' at the start of a
line are Python prompts. Bad things can happen if you fool either
mode.
Warning: If you do any editing *in* the process buffer *while* the
buffer is accepting output from Python, do NOT attempt to `undo' the
changes. Some of the output (nowhere near the parts you changed!) may
be lost if you do. This appears to be an Emacs bug, an unfortunate
interaction between undo and process filters; the same problem exists in
non-Python process buffers using the default (Emacs-supplied) process
filter."

Easier to use than explain. It sets the region to an `interesting'
block of succeeding lines. If point is on a blank line, it goes down to
the next non-blank line. That will be the start of the region. The end
of the region depends on the kind of line at the start:
- If a comment, the region will include all succeeding comment lines up
to (but not including) the next non-comment line (if any).
- Else if a prefix arg is given, and the line begins one of these
structures:
if elif else try except finally for while def class
the region will be set to the body of the structure, including
following blocks that `belong' to it, but excluding trailing blank
and comment lines. E.g., if on a `try' statement, the `try' block
and all (if any) of the following `except' and `finally' blocks
that belong to the `try' structure will be in the region. Ditto
for if/elif/else, for/else and while/else structures, and (a bit
degenerate, since they're always one-block structures) def and
class blocks.
- Else if no prefix argument is given, and the line begins a Python
block (see list above), and the block is not a `one-liner' (i.e.,
the statement ends with a colon, not with code), the region will
include all succeeding lines up to (but not including) the next
code statement (if any) that's indented no more than the starting
line, except that trailing blank and comment lines are excluded.
E.g., if the starting line begins a multi-statement `def'
structure, the region will be set to the full function definition,
but without any trailing `noise' lines.
- Else the region will include all succeeding lines up to (but not
including) the next blank line, or code or indenting-comment line
indented strictly less than the starting line. Trailing indenting
comment lines are included in this case, but not trailing blank
lines.

"Set region to body of def (or class, with prefix arg) enclosing point.
Pushes the current mark, then point, on the mark ring (all language
modes do this, but although it's handy it's never documented ...).
In most Emacs language modes, this function bears at least a
hallucinogenic resemblance to `\\[py-end-of-def-or-class]' and
`\\[py-beginning-of-def-or-class]'.
And in earlier versions of Python mode, all 3 were tightly connected.
Turned out that was more confusing than useful: the `goto start' and
`goto end' commands are usually used to search through a file, and
people expect them to act a lot like `search backward' and `search
forward' string-search commands. But because Python `def' and `class'
can nest to arbitrary levels, finding the smallest def containing
point cannot be done via a simple backward search: the def containing
point may not be the closest preceding def, or even the closest
preceding def that's indented less. The fancy algorithm required is
appropriate for the usual uses of this `mark' command, but not for the
`goto' variations.
So the def marked by this command may not be the one either of the
`goto' commands find: If point is on a blank or non-indenting comment
line, moves back to start of the closest preceding code statement or
indenting comment line. If this is a `def' statement, that's the def
we use. Else searches for the smallest enclosing `def' block and uses
that. Else signals an error.
When an enclosing def is found: The mark is left immediately beyond
the last line of the def block. Point is left at the start of the
def, except that: if the def is preceded by a number of comment lines
followed by (at most) one optional blank line, point is left at the
start of the comments; else if the def is preceded by a blank line,
point is left at its start.
The intent is to mark the containing def/class and its associated
documentation, to make moving and duplicating functions and classes
pleasant."

してください。
@ 自動インデント
py-modeはユーザーがインデントのことを考えなくていいよう
に出来るかぎり自動的に処理します。
RET py-newline-and-indent
改行したあと自動的に必要と思われる量のインデントを行います。インデント方
法は変数*py-indent-offset*で変えることができます。デフォルトではスペース
四つです。継続行で改行すると継続が始まった場所\(開き括弧など\)に応じてイ
ンデントされます。継続する行が継続される行に対してどれだけインデントする
かは変数*py-continuation-offset*で変えることができます。デフォルトではス
ペース四つです。コメント行には行の頭にシャープ二個がある「完全な」コメン
ト行と、それ以外の「普通の」コメント行があります。この「普通の」コメント
行が次の行のインデントに影響を与えるかを変数py-honor-comment-indentation
で変えることができます。py-honor-comment-indentationがnilなら「普通の」
コメント行はその後にくる行のインデントには影響しません。tならば「普通の」
コメント行はその後の行のインデントに影響を与えます。デフォルトではtです。
三重引用符内の文字列をインデントするかは変数py-align-multiline-strings-p
で変えることができます。tならインデントする、nilならば全くインデントせず、
左端に寄せます。デフォルトではtです。
TAB py-indent-line
現在ポイントがある行のインデントを補正します。
:\(コロン\) py-electric-colon
コロンを挿入して、必要があれば行を逆インデント\(左にずらす\)します。
BACKSPACE py-electric-backspace
ポイントが継続行でも、インデントされていないコメント行でもない行の左端の
文字上にあるか、もしくは空白文字だけの行にある場合、ポイントがあるブロックを
閉じるように空白を削除します。どのブロックを閉じたかはステータス部分に表示
されます。
それ以外の場合は普通のバックスペースと同じ\(backward-delete-char-untabify\)を
実行します。
@ 範囲選択
特定の範囲をリージョン指定する\(マークする\)ことができます。マ
ークした範囲はpy-shift-region-*で左右にシフトする、py-comment-regionで一
気にコメントアウトする、py-execute-regionで実行するといった操作をサポー
トします。
M-C-h py-mark-def-or-class
ポイントを含む最小のdef文全体をマークします。もしdef文がみつかれば、def
文全体がリージョンとなるようにポイントはdef文の最後に移動し、マークがdef
文の先頭につけられます。ただし、直前、もしくは一行の空行をはさんでコメン
ト行のブロックがある場合は、そのコメントブロックの頭にマークをつけます。
C-c C-k py-mark-block
現在いる行以降の「ブロック」をマークする。「ブロック」の範囲はこの
py-mark-blockがどんな行で実行したかに依存します。実行した行が
-コメント行なら、コメント行でない行までが「ブロック」になります。
-[if, elif, else, try, except, finally, for, while, def, class]のいずれか
の「ブロック」キーワードで始まる行で、かつuniversal-argumentが\(C-u C-c
C-k\)ある場合、その行に属すると思われる部分全体が「ブロック」になります。
つまりifで始まる行であれば、そのifに属すると思われるすべてのelif/elseが
「ブロック」としてマークされます。try/except/finally、while/elseなども同
じように全体がリージョンとしてマークされます。
-上記の「ブロック」キーワードで始まる行で、かつuniversal-argumentが与えら
れていなければ、その行よりも深くインデントされた部分が「ブロック」になり
ます。ただし、ブロックの最後にあるコメント行や空行は無視されます。
-上記のいずれでもない場合は次の空行か、実行した行よりも浅くインデントされ
た行までが「ブロック」になります。この場合は、ブロックの最後にある空行は
無視されますが、コメント行は無視されません。
@ コメントアウト
C-c # py-comment-region
リージョンをコメントアウトします。コメント文字列は'##'です。この変数は変
えない方が無難かと思いますが、変数py-block-comment-prefixで変えることも
できます。py-comment-regionはリージョン内の行頭に'## '\(シャープ・シャー
プ・スペース\)を挿入することでリージョンをコメントアウトします。空行は無
視されます。
-universal-argumentに数引数が与えられた場合\(C-u 2 C-c #\)、変数
py-block-comment-prefixを指定された回数だけ連続で挿入してコメントアウト
します。上記の例では'#### 'が行頭に挿入されます。この場合も空行は無視さ
れます。
-universal-argumetが与えられた場合\(C-u C-c #\)はアンコメント、つまりコ
メントをはずします。リージョン内にある、'##'で始まるすべての行のコメント
をはずします。シャープが一個だけの行や、ダブルシャープが行頭ではないとこ
ろにあるような行は無視されます。また、空行も無視されます。
universal-argumentで数を指定して\(C-u 2 C-c #\)コメントアウトされた行、
つまり行頭に偶数個のシャープが連続してある場合は一気にすべてのコメントを
はずすことができます。
@ 範囲シフト
C-c C-r py-shift-region-right
リージョンを変数py-indent-offsetの量だけ右にシフトします。
universal-argumentを与えると\(C-u 8 C-c C-r\)その量だけ右にシフトします。
C-c C-l py-shift-region-left
リージョンを変数py-indent-offsetの量だけ左にシフトします。リージョン内に
ある行のどれかがすでに左端によっていればエラーを出し、何も操作はしません。
-universal-argumentを与えると\(C-u 8 C-c C-r\)その量だけ左にシフトします。
-すでに左端に寄っている行がある場合はエラーを出して何も操作はしません。
-そうでない場合は、リージョンの内の各行を指定された量だけシフトします。
-もしシフトする量がインデント量よりも多く、途中で左端に寄ってしまった行が
あってもエラーを出さずに次の行をシフトします。
@ カーソル\(ポイント\)移動
C-c C-n py-next-statement
一つ前のステートメントに移動。ステートメントとは空行、コメント行、継続行
「以外」の行のことです。
C-c C-p py-previous-statement
一つ後のステートメントに移動。
M-C-a py-beginning-of-def-or-class
defブロックの先頭に移動します。ただし、ポイントがdef文の'd'にある時は一
つ前のdefに移動します。universal-argumentを与えると\(C-u M-C-a\)defでは
なくclassに移動します。
M-C-e py-end-of-def-or-class
現在行がdef文の場合はそのdefの最後に移動します。def文でない場合は
py-beginning-of-def-or-classで見つかったdef文の最後に移動します。それで
も見つからなかった場合は現在行よりも後にあるdef文の最後に移動します。
universal-argumentを与えると\(C-u M-C-e\)defではなくclassの最後に移動し
ます。
C-c C-u py-goto-block-up
現在行よりも浅くインデントされていて、コロン\(:\)で終わる行まで戻ります。
@ 簡易シェル
C-c ! py-shell
対話式pythonシェルを起動します。C-F4で終了します。shellバッファでの
キーバインドは以下の通りです。
M-p, M-n shell-history-previous/next
ポイントがコマンドライン上\(入力待ち状態になっている最後のプロンプトのあ
る行\)にある時、これまで実行したコマンドの履歴を挿入します。
shell-history-previousは実行した履歴を後ろに戻ります。shell-history-next
は前に進みます。、ポイントがコマンドライン上にない場合はエラーを出して、
何も操作はしません。
RET py-shell-send-input
ポイントがコマンドライン上にある場合はそのコマンドを実行します。ポイント
が以前に実行したコマンド上にある場合、そのコマンドを再び実行します。
C-a shell-goto-bol
ポイントがコマンドライン上にある場合、ポイントを行頭に持って行きます。
C-r shell-history-search-backward
入力済みの文字列にマッチするコマンド履歴を検索します。print 'a'という入
力履歴があれば'p'と入力した後C-rを押せば'p'からはじまる履歴が選択されま
す。
C-F6 py-restart-shell
Pythonシェルを再起動します。それまでimportしたモジュールや変数はクリアさ
れます。
C-F4 py-quit-shell
pythonシェルを終了、pythonシェルバッファを閉じます。
C-c C-p, C-c C-n comint-previous/next-prompt
現在いる行より一つ前、一つ後ろのプロンプトに移動します。
M-C-l comint-show-output
最後の出力の先頭を画面の最上部に表示します。出力が長すぎて確認できない場
合などに使います。
C-c C-u comint-kill-input
ポイントがコマンドライン上にある場合、プロンプト以降に入力した文字列を
削除します。
[注] オリジナルのpython-mode.elはcomintという機能を使ってコマンドの履歴
などを表示させますが、comint.el全体を移植する必要はないと判断して機能の
一部だけを移植しました。またshell3.lのコードも一部に使われています。現時
点ではemacsのpy-shellを完全再現することはできていません。
@ Python文の評価・実行 \(移植率80%くらい。\)
C-c | py-execute-region
指定したリージョンを実行します。結果が別バッファに表示されます。py-shell
バッファがあるときはそちらに表示します。実行処理をスタックしたり、
非同期で実行することはできません。
C-c C-s py-execute-string
ミニバッファプロンプトで指定したpythonコードを実行します。
C-c C-e py-execute-buffer
現在のバッファ内容を実行します。py-shellバッファがあるときはそちらに表示します。
@ Pydocによる簡易ヘルプ
C-c C-h py-help-at-point
http://www.python.org/doc/current/download.htmlからHTML Documentationを
ダウンロードして展開します。つぎに環境変数PYTHONDOCSをつくり、その値を
index.htmlがあるフォルダにセットします。Windowsを再起動後、
py-help-at-point\(C-c C-h\)でpydocによるヘルプを見ることが出来ます。")
