Python呼び出しSVN実装ファイル一括rename

Pythonを使用してosモジュールを呼び出し、import osはまずos.system()の使い方を見てみましょう.

>>> help(os.system)
Help on built-in function system in module nt:
system(...)
    system(command) -> exit_status
    
    Execute the command (a string) in a subshell.
>>>

subshellで指定したコマンド(このコマンドは文字列)を実行し、ステータス値を返します.
試してみる:

>>> os.system('time')

注意:dosコマンドラインに直接コマンドを入力するのとは異なり、コマンドに引用符''を付けて文字列にする必要があります.そうしないと、エラーが発生します.

>>> os.system(time)
Traceback (most recent call last):
  File "<pyshell#62>", line 1, in <module>
    os.system(time)
NameError: name 'time' is not defined
>>>

次に、SVNのコマンドを呼び出す方法について説明します.たとえば、svnのヘルプ情報を表示します.

>>> os.system('svn help')

指定したファイルの名前を変更したいので、まずSVNのrenameコマンドの使い方を見てみましょう.

>>> os.system('svn help rename')
move (mv, rename, ren): Move and/or rename something in working copy or repository.
usage: move SRC... DST
When moving multiple sources, they will be added as children of DST,
which must be a directory.
  Note:  this subcommand is equivalent to a 'copy' and 'delete'.
  Note:  the --revision option has no use and is deprecated.
  SRC and DST can both be working copy (WC) paths or URLs:
    WC  -> WC:   move and schedule for addition (with history)
    URL -> URL:  complete server-side rename.
  All the SRCs must be of the same type.
Valid options:
  -r [--revision] ARG      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED
  -q [--quiet]             : print nothing, or only summary information
  --force                  : force operation to run
  --parents                : make intermediate directories
  -m [--message] ARG       : specify log message ARG
  -F [--file] ARG          : read log message from file ARG
  --force-log              : force validity of log message source
  --editor-cmd ARG         : use ARG as external editor
  --encoding ARG           : treat value as being in charset encoding ARG
  --with-revprop ARG       : set revision property ARG in new revision
                             using the name[=value] format
Global options:
  --username ARG           : specify a username ARG
  --password ARG           : specify a password ARG
  --no-auth-cache          : do not cache authentication tokens
  --non-interactive        : do no interactive prompting
  --trust-server-cert      : accept unknown SSL server certificates without
                             prompting (but only with '--non-interactive')
  --config-dir ARG         : read user configuration files from directory ARG
  --config-option ARG      : set user configuration option in the format:
                                 FILE:SECTION:OPTION=[VALUE]
                             For example:
                                 servers:global:http-library=serf

はい、move(mv,rename,ren):Move and/or rename something in working copy or repository.move(またはrename)コマンドを使用して移動し、名前を変更する操作が表示されます.もちろんmv,renを略記することもできます.
使用する前に、簡単な例で試してみましょう.

>>> os.system('svn log')
svn：'.' is not a working copy

現在のディレクトリは(SVNの)作業コピーではありません!logコマンドの使い方を見てみましょう.
 

log: Show the log messages for a set of revision(s) and/or file(s).
usage: 1. log [PATH]
       2. log URL[@REV] [PATH...]
  1. Print the log messages for a local PATH (default: '.').
     The default revision range is BASE:1.
  2. Print the log messages for the PATHs (default: '.') under URL.
     If specified, REV determines in which revision the URL is first
     looked up, and the default revision range is REV:1; otherwise,
     the URL is looked up in HEAD, and the default revision range is
     HEAD:1.
  Multiple '-c' or '-r' options may be specified (but not a
  combination of '-c' and '-r' options), and mixing of forward and
  reverse ranges is allowed.
  With -v, also print all affected paths with each log message.
  With -q, don't print the log message body itself (note that this is
  compatible with -v).
  Each log message is printed just once, even if more than one of the
  affected paths for that revision were explicitly requested.  Logs
  follow copy history by default.  Use --stop-on-copy to disable this
  behavior, which can be useful for determining branchpoints.
  Examples:
    svn log
    svn log foo.c
    svn log http://www.example.com/repo/project/foo.c
    svn log http://www.example.com/repo/project foo.c bar.c
Valid options:
  -r [--revision] ARG      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED
  -q [--quiet]             : print nothing, or only summary information
  -v [--verbose]           : print extra information
  -g [--use-merge-history] : use/display additional information from merge
                             history
  -c [--change] ARG        : the change made in revision ARG
  --targets ARG            : pass contents of file ARG as additional args
  --stop-on-copy           : do not cross copies while traversing history
  --incremental            : give output suitable for concatenation
  --xml                    : output in XML
  -l [--limit] ARG         : maximum number of log entries
  --with-all-revprops      : retrieve all revision properties
  --with-no-revprops       : retrieve no revision properties
  --with-revprop ARG       : retrieve revision property ARG
Global options:
  --username ARG           : specify a username ARG
  --password ARG           : specify a password ARG
  --no-auth-cache          : do not cache authentication tokens
  --non-interactive        : do no interactive prompting
  --trust-server-cert      : accept unknown SSL server certificates without
                             prompting (but only with '--non-interactive')
  --config-dir ARG         : read user configuration files from directory ARG
  --config-option ARG      : set user configuration option in the format:
                                 FILE:SECTION:OPTION=[VALUE]
                             For example:
                                 servers:global:http-library=serf

OK!logにコマンドを追加するパスは、設定されていない場合は現在のディレクトリです.次に、まず考えられるのは、コマンドの後ろにパスを付けることです.

>>> os.system('svn log E:\test')

しかし、複数回の操作を行うと、これでは不便です.パスを作業ディレクトリに切り替えたほうがいいです.では、DOSコマンドを使用して操作を続けます.

>>> os.system('E:')
0
>>> os.getcwd()
'C:\\Python26'
>>>

残念ながら現在の経路は変わっていません.OS.system呼び出しのコマンドはsubshellで実行されるため、python shellの現在のディレクトリは変更されません.ここではosモジュールのFUNCTIONを使用する必要があります.    chdir(...)         chdir(path)                  Change the current working directory to the specified path.

>>> os.chdir('E:\test')
>>> print os.getcwd()
E:\test

作業ディレクトリをrootpathに設定し、このディレクトリの下のTest 01_2013_11_15_01-001.txt名前をTest 01_に変更2013_11_15_01_001.txt :

>>> rootpath=r'E:\test'
>>> os.system('svn move Test01_2013_11_15_01-001.txt Test01_2013_11_15_01_001.txt')
A         Test01_2013_11_15_01_001.txt
D         Test01_2013_11_15_01-001.txt
0

はい、長い間忙しくて単一のファイルの名前を変えるだけで、これは絶対に私の初心ではありません.どうやって一括改名しますか?ファイル名を変数にあげてみますか?まず、ディレクトリの下にあるファイルを取得します.

>>> filenames = os.listdir(path)

次に、変更する文字と置換する文字を定義します.

>>> source_char = raw_input('Enter the characters that you want to modify:')
Enter the characters that you want to modify:-0
>>> copy_char = raw_input('Enter the characters that you want to get:')
Enter the characters that you want to get:_0
>>> for old_file in filenames:
 new_file = string.replace(old_file,source_char,copy_char)
 os.system('svn move old_file new_file')

戻り値は1で、操作に失敗しました.
renameコマンド実行時に変数old_をfileとnew_fileはファイル名ではなく普通の文字として扱われます.
解決策は簡単です.ファイル名変数が通常の文字伝達になる前に、renameコマンドを文字列に書きます. svnren=r'svn move '+old_file+' '+new_file  os.system(svnren)
