2 スクリプトによる方法

• `rails routes'が出す不用な情報を除いて整形して出す
  • "turbo/native", "/action_mailbox/"," /active_storage/"行を削除
  • 余白を整理

• とりあえずawkで作ってみた(routes.rake)

  task routes: :environment do
  	  puts `bundle exec rails routes | awk '
  	        BEGIN {
  	                n = 0
  	        }
  	        $0 ~ /^[[:space:]]*Prefix[[:space:]]+/{
  	                n += 1
  	                lines[n] = $0
  	                mrn = length($1)
  	                match($0, /^[[:space:]]+/)
  	                lc = RLENGTH
  	                mpn = length("URI Pattern")
  	                match($0, /URI Pattern/)
  	                rc = RSTART + RLENGTH
  	                next
  	        }
  	        $0 ~ /turbo\\/native|\\/action_mailbox\\/|\\/active_storage\\//{ next }
  	        {
  	                n += 1
  	                lines[n] = $0
  	                if (length($1) > mrn) {
  	                        mrn = length($1)
  	                        match($0, /^[[:space:]]+/)
  	                        lc = RLENGTH
  	                }
  	                if (length($3) > mpn) {
  	                        mpn = length($3)
  	                        regex = $3
  	                        gsub(/[\\/\\(\\)\\[\\]\\{\\}\\*\\?\\.\\+\\-\\"]/, "\\\\\\\\&", regex)
  	                        match($0, regex)
  	                        rc = RSTART + RLENGTH
  	                }
  	        }
  	        END {
  	                for (i = 1; i <= n; i++) {
  	                        left = substr(lines[i], 1, rc)
  	                        left = substr(left, lc + 1)
  	                        right = substr(lines[i], rc)
  	                        sub(/^[[:space:]]*/, "", right)
  	                        print left right
  	                }
  	    }'`
  	end

• 出力結果はこんなかんじ
