It 'outputs texts'
output() {

  #|bbb
  #|ccc
  echo "end" # you can write code here
}
When call output
The line 1 of output should eq 'start'
The line 2 of output should eq 'aaa'
The line 3 of output should eq 'bbb'
The line 4 of output should eq "ccc"
The line 5 of output should eq 'end'
End

It 'sets to variable'
output() {
  texts=$(
    %text
    #|aaa
    #|bbb
    #|ccc
  )
  echo "$texts"
}
When call output
The line 1 of output should eq 'aaa'
The line 2 of output should eq 'bbb'
The line 3 of output should eq "ccc"
End

It 'outputs texts with filter'
output() {
  %text | tr 'a-z_' 'A-Z_'
  #|abc
}
When call output
The output should eq 'ABC'

Describe 'variable expansion'
Before 'text=abc'

Example 'not expand variable (default)'
output() {
  %text:raw

}
When call output
The output should eq '$text'
End

Example 'expand variable'
output() {
  %text:expand

}
When call output
The output should eq 'abc'

  if true; then
    set -- 1 2 3 4 5
    while [ $# -gt 0 ]; do
      %text:expand | tr 'a-z_' 'A-Z_'
      #|value $(($1 * 10))
      shift
    done
  else
    %text
    #|text

The line 2 of output should eq 'VALUE 20'
The line 3 of output should eq 'VALUE 30'
The line 4 of output should eq "VALUE 40"
The line 5 of output should eq 'VALUE 50'
