Hi Bruce,
This has to do with the way I am importing subs from modules.
When importing subs, I like to declare which subs I
am importing. Otherwise my code is a nightmare to maintain.
"Where the heck did that subs comes from? Is its a system
subs or ...."
For instance, in Perl 5:
use Term::ANSIColor qw ( BOLD BLUE RED GREEN RESET );
imports "BOLD BLUE RED GREEN RESET".
Perl 6 has improved on this with selective importing and exporting.
The ":" is part of the tag:
https://docs.perl6.org/language/modules#Exporting_and_selective_importing
For instance:
PrintColors.pm6 exports with:
sub PrintBlue ( **@args ) is export( :PrintBlue ) { print
color('bold'), color('blue'), |@args, color('reset'); }
The tag is `is export( :PrintBlue )`
And imports with:
use PrintColors :PrintRed, :PrintGreen, :PrintBlue, :PrintErr,
:PrintRedErr, :PrintGreenErr, :PrintBlueErr;
What I am after is a way to run a one liner with
this type of export using the "-M" switch".
perl6 -I /home/linuxutil/p6lib -M "PrintColors :PrintBlue" -e
'PrintBlue( "Blue\n" );'
Could not find PrintColors :PrintBlue at line 1 in:
-T
