![]() ![]() There are multiple ways you can split a string or strings of multiple delimiters in python. ~$ raku -e 'print $*IN.You need to split a string into fields, but the delimiters aren’t consistent throughout the string. ![]() ~$ raku -e 'print $*IN.split(q) ' <<< 'one_two_three_four_five' So the last (zero-indexed) element is, the second-to-last is, etc. The way to numerically index from the right end in Raku is to use the * "whatever-star" idiom. If you want to take elements from the right end, use tail in a similar manner. You can take the first element after splitting with head, or the first 2 elements with head(2). Putting these two options together: A=$(raku -e '$*IN.split(q).print ' <<< 'one_two_three_four_five')ī=$(raku -e '$*IN.split(q).print ' <<< 'one_two_three_four_five')įinally, a word about indexing. Also, if you have an issue with quoting, then the. This answer complements the awk answer by You can place print at the right end of the method chain, if you find that more readable. Also note that while foo_ would be split into foo only in ksh/bash/yash, it's split into foo and the empty string in zsh. ![]() Where $=string requests word splitting explicitly (glogging is still not done so doesn't need to be disabled globally). So some changes need to be done to get this working in zsh: IFS=_ arr=( $=string ) In zsh, arrays start in 1, and no split+glob is performed by default upon parameter expansions. ![]() There is no equivalent for POSIX shells, as many POSIX shells do not have arrays.įor shells that have arrays may be as simple as (tested working in attsh, lksh, mksh, ksh, and bash, but not zsh): set -f IFS=_ arr=($string)īut with a lot of additional plumbing to keep and reset variables and options: string='one_* *_three_four_five' Would split an empty string into one empty element, but would give an empty list if $string was unset. string='one_two_three_four_five'įirst="$") Note that this code assumes that there is the requisite number of fields, otherwise the last field is repeated. Using only POSIX sh constructs, you can use parameter substitution constructs to parse one delimiter at a time. ![]()
