This model provides some miscellaneous text processing routines not
provided by core Raku. (Note it replaces the now-deprecated
Note this is version
2.0.0 which introduces a new API 2 for
strip-comment routine. See the examples below for its use.
The old signature is still usable, but it is deprecated
and will be removed in version
use Text::More :ALL;
Note that individual subroutines may also be exported:
use Text::More :strip-comment; # the '#' is the default comment character my $line = " some text # a comment"; $line = strip-comment $line; say $line; # OUTPUT: « some text ␤»
If you want to be fancier, return the stripped line and its comment, with both strings normalized (trimmed of leading and trailing spaces, contiguous spaces collapsed to one):
# define your own comment character(s) # save the comment and normalize the returned strings my ($line, $comm) = strip-comment $line, :mark<%%>, :save-comment, :normalize; say $line; # OUTPUT: «some text␤» say $comm; # OUTPUT: «a comment␤»
The default behavior is to find the first comment character in the input string, but you may choose to start the search from the end of the input string:
my $line = "text 1 # text 2 # comment"; $line = strip-comment $line, :reverse; say $line; # OUTPUT: «text 1 # text 2 ␤»
Note that the routine is line oriented, so embedded newlines may give unexpected results:
my $line = q:to/HERE/; text 1 # comment 1 text 2 # comment 2 HERE $line = strip-comment $line say $line; # OUTPUT: «text 1 ␤»
