---------------------------------------------------------------------- (0003392) stephane (reporter) - 2016-09-23 06:59 http://austingroupbugs.net/view.php?id=375#c3392 ---------------------------------------------------------------------- Re: http://austingroupbugs.net/view.php?id=375#c3391 Mark, you're missing the point I'm trying to make since the beginning. What you're describing (about quoting of RE operators) is the zsh/bash31 behaviour, not the one of bash32+/ksh93 or what this proposal specifies. Quoting the proposal: > string =~ regex > true if string matches the extended regular expression (ERE) > regex as defined in section 9.4; otherwise false. Characters > that are quoted in regex (using <backslash>, single-quote, or > double-quote) shall not be treated as an ERE special character, > but shall instead be treated as an ERE ordinary character and > thus only match themselves. See also appendix B So [[ $a =~ "foo|bar" ]] and s='foo|bar'; [[ $a =~ "$s" ]] is testing whether $a contains "foo|bar" (as if by calling regcomp("foo\\|bar")), [[ $a =~ foo|bar ]] is not allowed and re='foo|bar'; [[ $a =~ $re ]] is matching $a against the foo|bar ERE (regcomp("foo|bar")). With bash-4.3: <pre> $ ltrace -e regcomp bash -c '[[ a =~ "a|b" ]]' bash->regcomp(0x7ffff013f3b0, "a\\|b", 1) = 0 +++ exited (status 1) +++ $ ltrace -e regcomp bash -c '[[ a =~ a|b ]]' bash->regcomp(0x7fff33a64d50, "a|b", 1) = 0 +++ exited (status 0) +++ $ ltrace -e regcomp bash -c 're="a|b"; [[ a =~ "$re" ]]' bash->regcomp(0x7fffba6ec710, "a\\|b", 1) = 0 +++ exited (status 1) +++ $ ltrace -e regcomp bash -c 're="a|b"; [[ a =~ $re ]]' bash->regcomp(0x7ffe497b2700, "a|b", 1) = 0 +++ exited (status 0) +++ $ ltrace -e regcomp bash -c '[[ a =~ ["a|b"] ]]' bash->regcomp(0x7ffe32decc20, "[a|b]", 1) = 0 +++ exited (status 0) +++ $ ltrace -e regcomp bash -c '[[ a =~ "[a|b]" ]]' bash->regcomp(0x7ffea326a1e0, "\\[a\\|b]", 1) = 0 +++ exited (status 1) +++ </pre> With zsh-5.1.1 <pre> $ ltrace -e regcomp zsh -c '[[ a =~ "a|b" ]]' regex.so->regcomp(0x7ffc3aaa2ac0, "a|b", 1) = 0 +++ exited (status 0) +++ $ ltrace -e regcomp zsh -c '[[ a =~ a|b ]]' zsh:1: parse error near `|' +++ exited (status 1) +++ </pre> Issue History Date Modified Username Field Change ====================================================================== 2011-02-07 18:34 dwheeler New Issue 2011-02-07 18:34 dwheeler Status New => Under Review 2011-02-07 18:34 dwheeler Assigned To => ajosey 2011-02-07 18:34 dwheeler Name => David A.
