Javaのステップ数を数える

Posted at

Javaに限らず,C系の言語だと似たようなものかも.

コメントや空行などを除いて行を数える:

$ find . -name '*.java' -type f | xargs grep -Ev '^[[:space:]]*((/?\*.*/?)|(//.*))$' | wc -l

ブレイスやセミコロンだけの行を除くならこんな感じか:

$ find . -name '*.java' -type f | xargs grep -Ev '^[[:space:]]*((/?\*.*/?)|(//.*)|[{};][[:space:]]*)$' | wc -l
