NAME<\/a> MDK::Common::Various \u2212 miscellaneous functions<\/p>\n use MDK::Common::Various qw(:all);<\/p>\n first( LIST<\/small> )<\/p>\n returns the first value. “first(XXX)” is an alternative for “((XXX)[0])”<\/p>\n second( LIST<\/small> )<\/p>\n returns the second value. “second(XXX)” is an alternative for “((XXX)[1])”<\/p>\n top( LIST<\/small> )<\/p>\n returns the last value. “top(@l)” is an alternative for $l[$#l]<\/p>\n to_bool( SCALAR<\/small> )<\/p>\n returns a value in { 0, 1 }<\/p>\n to_int( STRING<\/small> )<\/p>\n extracts the number from the string. You could use directly “int “11 foo””, but you\u2019ll get Argument “11 foo” isn\u2019t numeric in int<\/i>. It also handles returns 11 for “foo 11 bar”<\/p>\n to_float( STRING<\/small> )<\/p>\n extract a decimal number from the string<\/p>\n bool2text( SCALAR<\/small> )<\/p>\n returns a value in { “true”, “false” }<\/p>\n bool2yesno( SCALAR<\/small> )<\/p>\n returns a value in { “yes”, “no” }<\/p>\n text2bool( STRING<\/small> )<\/p>\n inverse of “bool2text” and “bool2yesno”<\/p>\n chomp_( STRING<\/small> )<\/p>\n non-mutable version of chomp: do not modify the argument, returns the chomp\u2019ed value. Also works on lists: “chomp_($a, $b)” is equivalent to “chomp($a) ; chomp($b) ; ($a,$b)”<\/p>\n backtrace()<\/b><\/p>\n returns a string describing the backtrace. eg:<\/p>\n sub g { print “oopsn”, backtrace() } gives<\/p>\n oops internal_error( STRING<\/small> )<\/p>\n another way to “die” with a nice error message and a backtrace<\/p>\n noreturn()<\/b><\/p>\n use this to ensure nobody uses the return value of the function. eg:<\/p>\n sub g { print “g calledn”; noreturn } gives<\/p>\n test.pl:3: main::f() expects a value from main::g(), but main::g() doesn’t return any value<\/p>\n MDK::Common<\/p>\n MDK::Common::Various \u2212 miscellaneous functions <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[3007,3566],"class_list":["post-7240","post","type-post","status-publish","format-standard","hentry","category-sin-categoria","tag-man3","tag-mdkcommonvarious"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/7240","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=7240"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/7240\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=7240"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=7240"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=7240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
