* regexp/syntax: exclude full range from String negation caseKeegan Carruthers-Smith2019-05-221-0/+1
| | | | | | | | | | | If the char class is 0x0-0x10ffff we mistakenly would String that to `[^]`, which is not a valid regex.

* all: use strings.Builder instead of bytes.Buffer where appropriateBrad Fitzpatrick2018-03-261-3/+3
| | | | | | | | | | | | | | I grepped for "bytes.Buffer" and "buf.String" and mostly ignored test files. I skipped a few on purpose and probably missed a few others, but otherwise I think this should be most of them.

* all: make copyright headers consistent with one space after periodBrad Fitzpatrick2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.

* regexp/syntax: fix factoring of common prefixes in alternationsPaul Wankadia2016-01-081-3/+4
| | | | | | | | | | | | | In the past, `a.*?c|a.*?b` was factored to `a.*?[bc]`. Thus, given "abc" as its input string, the automaton would consume "ab" and then stop (when unanchored) whereas it should consume all of "abc" as per leftmost semantics. Fixes #13812.

* regexp/syntax: fix handling of \Q...\ERuss Cox2015-12-011-0/+2
| | | | | | | | | | | | | | | It's not a group: must handle the inside as a sequence of literal chars, not a single literal string. That is, \Qab\E+ is the same as ab+, not (ab)+. Fixes #11187.
