Introduction

This is about how to deal with the problem that 0 is omitted and 1 is output when trying to CSV output a numerical value such as 001 that starts with 0.

Correspondence

'="001"'

If it is a fixed value, this is not a problem, but if it is a variable, the expression is not expanded, so do as follows.

#Note that it is enclosed in double quotes
%Q{="#{hoge}"}

Rubocop compliant,

#Note that it is enclosed in double quotes
%(="#{hoge}")
