Perl::Critic(perlcritic)を使用して静的解析、コーディング規約テストを実施(実施編:コマンド)

Last updated at Posted at 2017-02-26

Perlの静的解析、コーディング規約テストを実施する為にPerl::Criticを使用する事になったので、内容を残しておきます。

dockerのubuntuにて実行
「Ubuntu 14.04.3 LTS」
(実行日付:2017/02/26)

コマンド実行

コマンド:
perlcritic 「ファイル名称」

(実行結果)

# perlcritic testCode.pl
Code before strictures are enabled at line 1, column 1.  See page 429 of PBP.  (Severity: 5)
#

(テスト対象ファイル内容)

# cat testCode.pl
print "Hello world";

# 

出力結果を対象外とする場合

オプション:
--exclude

(実行例)

# perlcritic --exclude=stric testCode.pl     
testCode.pl source OK
# 

severity設定

番号(1〜5)を設定して出力する内容を設定します。
2を設定すると、2以上の内容を出力します。
番号と意味は以下の通りです。

SEVERITY NAME   ...is equivalent to...   SEVERITY NUMBER
--------------------------------------------------------
--severity gentle                           --severity 5
--severity stern                            --severity 4
--severity harsh                            --severity 3
--severity cruel                            --severity 2
--severity brutal                           --severity 1

オプション:
--severity

(実行例)

# perlcritic --severity=2 testCode.pl
Module does not end with "1;" at line 1, column 1.  Must end with a recognizable true value.  (Severity: 4)
Code not contained in explicit package at line 1, column 1.  Violates encapsulation.  (Severity: 4)
No package-scoped "$VERSION" variable found at line 1, column 1.  See page 404 of PBP.  (Severity: 2)
Code before strictures are enabled at line 1, column 1.  See page 429 of PBP.  (Severity: 5)
Code before warnings are enabled at line 1, column 1.  See page 431 of PBP.  (Severity: 4)

コマンドのhelpを実行する事で、その他の設定内容を確認する事が出来ます。

コマンド:
perlcritic --help
