* unicode: upgrade to version 9.0.0Marcel van Lohuizen2016-06-281-1/+1
| | | | | | | | | | | | | | | | | | Changes beyond generated tables: - Now supports aliases to handle deprecated property classes. - Some Mongolian letters are now modifiers. Other changes: - strconv: newly generated table to be in sync - regexp/syntax: updated maxFold Fixes #16191 Change-Id: I56bdf21ee2f775f2a82d0465b3772faf5c24cb61 Reviewed-on: https://go-review.googlesource.com/24496 Run-TryBot: Marcel van Lohuizen <mpvl@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
* all: single space after period.Brad Fitzpatrick2016-03-021-15/+15
| | | | | | | | | | | | | | | | | | | | The tree's pretty inconsistent about single space vs double space after a period in documentation. Make it consistently a single space, per earlier decisions. This means contributors won't be confused by misleading precedence. This CL doesn't use go/doc to parse. It only addresses // comments. It was generated with: $ perl -i -npe 's,^(\s*// .+[a-z]\.) +([A-Z]),$1 $2,' $(git grep -l -E '^\s*//(.+\.) +([A-Z])') $ go test go/doc -update Change-Id: Iccdb99c37c797ef1f804a94b22ba5ee4b500c4f7 Reviewed-on: https://go-review.googlesource.com/20022 Reviewed-by: Rob Pike <r@golang.org> Reviewed-by: Dave Day <djd@golang.org> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>
* 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 Wankadia2016-01-081-4/+11
| | | | | | | | | | | | | 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 Cox2015-12-011-1/+8
| | | | | | | | | | | | | | | 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.
