Replace CONDENSE with string function

Replaces the CONDENSE statement with the string processing function condense( ).

This rule is part of the essential profile, as it is explicitly demanded by the Clean ABAP Styleguide.

References

Options

  • Explicitly specify parameter val = ... even if no other parameters are used
  • Explicitly specify parameter del = ` `, except for NO-GAPS
  • Explicitly specify parameter from = ` ` for NO-GAPS
  • Keep parameters on one line (see rule 'Align parameters and components', option 'Keep other one-liners')

Examples

  METHOD replace_condense.
    CONSTANTS lc_abc_with_gaps TYPE string VALUE `  a   b   c  `.

    DATA lv_text_a   TYPE char30 VALUE lc_abc_with_gaps.
    DATA lv_text_b   TYPE char30 VALUE lc_abc_with_gaps.
    DATA lv_text_c   TYPE char30 VALUE lc_abc_with_gaps.
    DATA lv_string_a TYPE string VALUE lc_abc_with_gaps.
    DATA lv_string_b TYPE string VALUE lc_abc_with_gaps.

    " condense first text field to 'a b c', second one to 'abc'
    CONDENSE lv_text_a.
    CONDENSE lv_text_b NO-GAPS.

    " condense first string to 'a b c', second one to 'abc'
    CONDENSE lv_string_a.
    CONDENSE lv_string_b NO-GAPS.

    " condense text field with offset 5 and length 7 to `  a  b c`
    " (specifying offset and length in write positions is possible for text fields, but not for strings)
    CONDENSE lv_text_c+5(7).
  ENDMETHOD.

Resulting code:
