2010-02-28Count utf8 runes, not bytes when determining string width. NoteStephen Ma3-2/+6
that pad() still counts bytes, but it's currently only used for 1 byte runes. Fixes issue 612. R=r CC=golang-dev http://codereview.appspot.com/217064 Committer: Rob Pike <r@golang.org>

- use an interface {Get()} - implement Get for maps, slices - for slices, retrieves the address of the end of the array, which will give the same value for every slice of the same array. R=rsc CC=golang-dev http://codereview.appspot.com/179129

2009-12-15 1) Change default gofmt default settings forRobert Griesemer3-409/+409
parsing and printing to new syntax. Use -oldparser to parse the old syntax, use -oldprinter to print the old syntax. 2) Change default gofmt formatting settings to use tabs for indentation only and to use spaces for alignment. This will make the code alignment insensitive to an editor's tabwidth. Use -spaces=false to use tabs for alignment. 3) Manually changed src/exp/parser/parser_test.go so that it doesn't try to parse the parser's source files using the old syntax (they have new syntax now). 4) gofmt -w src misc test/bench 2nd set of files.

2009-12-06Make printing faster by avoiding mallocs and some other advances.Rob Pike3-378/+386
Roughly 33% faster for simple cases, probably more for complex ones. Before: mallocs per Sprintf(""): 4 mallocs per Sprintf("xxx"): 6 mallocs per Sprintf("%x"): 10 mallocs per Sprintf("%x %x"): 12 Now: mallocs per Sprintf(""): 2 mallocs per Sprintf("xxx"): 3 mallocs per Sprintf("%x"): 5 mallocs per Sprintf("%x %x"): 7 Speed improves because of avoiding mallocs and also by sharing a bytes.Buffer between print.go and format.go rather than copying the data back after each printed item. Before: fmt_test.BenchmarkSprintfEmpty 1000000 1346 ns/op fmt_test.BenchmarkSprintfString 500000 3461 ns/op fmt_test.BenchmarkSprintfInt 500000 3671 ns/op Now: fmt_test.BenchmarkSprintfEmpty 2000000 995 ns/op fmt_test.BenchmarkSprintfString 1000000 2745 ns/op fmt_test.BenchmarkSprintfInt 1000000 2391 ns/op fmt_test.BenchmarkSprintfIntInt 500000 3751 ns/op I believe there is more to get but this is a good milestone.

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia1-2/+2
the bash scripts and makefiles for building go didn't take into account the fact $GOROOT / $GOBIN could both be directories containing whitespaces, and was not possible to build it in such a situation. this commit adjusts the various makefiles/scripts to make it aware of that possibility, and now it builds successfully when using a path with whitespaces as well.
