Here are a few different ways to take ~”numbered” slist > {'1.txt','2.txt','3.txt'};~
and get a list where =.txt is stripped from each element.
bundle agent __main__
{
vars:
"numbered" slist => {'1.txt','2.txt','3.txt'};
# Using maplist and basename()
"l_stripped_0"
slist => maplist( basename( "$(this)", ".txt" ), numbered );
# Using an associative (aka classic) array, basename and getvalues()
"a_stripped_1[$(numbered)]"
string => basename( "$(numbered)", ".txt" );
"l_stripped_1" slist => getvalues( "a_stripped_1" ); # no order promised!
"l_stripped_1a" slist => sort( getvalues( "a_stripped_1" ), "int" ); # sorted numerically
# Using associatiative (aka classic) array, with regex replace, nth and with
# to get the desirable portion of the string into both the key and the value
"a_stripped_2[$(with)]"
with => regex_replace( $(numbered), "(.*).txt", "$1", "" ),
string => nth( string_split( $(numbered), ".txt", inf ), 0);
"l_stripped_2a" slist => getindices( a_stripped_2 ); # no order promised!
"l_stripped_2b" slist => getvalues( a_stripped_2 ); # no order promised!
#By converting to a string, and back to a list while using regex_replace to munge the string
"l_stripped_3"
slist => string_split( regex_replace( join( " ", numbered ), ".txt", "", "g" ),
"\s+", inf ) ;
}
