HELP STRUTILS                                  Everyday string operations

    uses strutils;

Byte-oriented string utilities (see HELP * UTF8 for code-point-aware
operations).  Separators may be a character (`,`) or a non-empty
string ('::').

str_split(S, SEP) -> LIST
    'a,b,,c' on `,` -> ['a' 'b' '' 'c'] — adjacent separators yield
    empty fields.

str_join(LIST, SEP) -> S
    Inverse of str_split.

str_trim(S) -> S            both ends
str_ltrim(S) -> S           left only
str_rtrim(S) -> S           right only
    Strip spaces, tabs, newlines, returns.

str_starts(PREFIX, S) -> BOOL
str_ends(SUFFIX, S) -> BOOL

str_replace(S, OLD, NEW) -> S
    Every occurrence of OLD (non-empty) replaced by NEW.

str_lines(S) -> LIST
    Split on newlines; accepts \n and \r\n; a trailing newline does
    not produce a phantom empty last line.

str_repeat(S, N) -> S
str_padl(S, N, CHAR) -> S   pad on the left to width N
str_padr(S, N, CHAR) -> S   pad on the right

str_lower(S) -> S
str_upper(S) -> S
    ASCII case mapping only (bytes >= 128 pass through unchanged).
