新規アプリは単純に wc -l で行数(ステップ数)を数えれば良いですが
変更がある場合、単純にdiffを取得すると 差分は2行として数えられます。
で、diffstatのファイル毎出力の追加分と、削除分の多い方を合計すればよい気がします。なんとなく
$ svn diff -r 1144:1140 https://example.com/repos/xing/trunk | diffstat -f 4 lib/Xing/Model/Summary/HExportStream.pm | 9 3 6 0 +++------ lib/Xing/Model/Summary/HJuchuu.pm | 16 8 8 0 ++++++++-------- tmpl/HSummary/SummaryList.html | 12 6 6 0 ++++++------ 3 files changed, 17 insertions(+), 20 deletions(-)
※上記の「9 3 6」の値は、3が追加で、6が削除分です
↓こちらはdiffstatのヘルプ
$ diffstat --help Usage: diffstat [options] [files] Reads from one or more input files which contain output from 'diff', producing a histogram of total lines changed for each file referenced. If no filename is given on the command line, reads from standard input. Options: -c prefix each line with comment (#) -e FILE redirect standard error to FILE -f NUM format (0=concise, 1=normal, 2=filled, 4=values) -h print this message -k do not merge filenames -l list filenames only -n NUM specify minimum width for the filenames (default: auto) -o FILE redirect standard output to FILE -p NUM specify number of pathname-separators to strip (default: common) -r NUM specify rounding for histogram (0=none, 1=simple, 2=adjusted) -t print a table (comma-separated-values) rather than histogram -u do not sort the input list -v makes output more verbose -V prints the version number -w NUM specify maximum width of the output (default: 80) $
