sdiff.py

2つのテキストファイルまたはディレクトリの差分を取り、人間にとって分かりやすい比較形式で表示します。 差分取得結果は等幅フォントを表示するターミナル(コマンドライン)上で直接表示できます。

Compare two text files or directories; generate the resulting delta.

ダウンロード(Download)

  • Current

sdiff.py 1.3.2

current "stable" version.

Show colored diff and automatic width detection.

  • History

sdiff.py 1.2.1

old "stable" version.

able to parse Unified diff formated text from stdin. by include "unidiff" library. Thanks a lot !! Visit here https://github.com/matiasb/python-unidiff

インストール(Installation)

特に無し。 ヴァージョン 2.7, 3.5 のPythonが実行可能な環境であること。

Do nothing. need Python ver 2.7 or 3.5.

実行例(Example)

以下のような2つのテキストファイルtext1.txtとtext2.txtを用意して

text1.txt:

1. Beautiful is better than ugly.
2. Explicit is better than implicit.
3. Simple is better than complex.
4. Complex is better than complicated.

text2.txt:

1. Beautiful is better than ugly.
3.   Simple is better than complex.
4. Complicated is better than complex.
5. Flat is better than nested.

色付けをしない場合はプレーンテキストの内容で差分が完結する。 The difference is complete with the contents of plain text if you do not want the colored

sdiff.py text1.txt text2.txt -w 93 --color never

使い方(Usage)

コマンドラインで以下のように指定する。 2つのテキストファイルまたはディレクトリの差分を表示することができる。 引数に比較対象を指定しなかった場合は標準入力からのUnified diff formatのテキストを待つ。

It is possible to show the differences between two text files or directories. and waits for the text of the Unified diff format from standard input if there is not an argument.

ヴァージョン管理システムと連携する場合

注釈

sdiff.pyに対してパス(環境変数PATH)を通しておくこと。

Subversionと連携する場合

  • 単純に実行 svn diff --diff-cmd sdiff.py

  • オプションを渡す場合 svn diff --diff-cmd sdiff.py -x "-w 180"

  • もっと簡単に svn diff | sdiff.py

Mercurialと連携する場合

extdiffを使う場合はホームディレクトリ直下の~/.hgrc (or mercurial.ini for Windows)に以下の内容を追加しておく

~/.hgrc:

[extensions]

extdiff =
  • 単純に実行 hg extdiff -p sdiff.py

  • オプションを渡す場合 hg extdiff -p sdiff.py -o "-w 180"

  • もっと簡単に hg diff | sdiff.py
