2010-06-28fmt.Printf: fix bug in handling of %#v.Rob Pike1-18/+7
nice side effect: slices now obey their format verb. example: fmt.Printf("%q\n", []string{"a"}) R=rsc CC=golang-dev http://codereview.appspot.com/1729045
2010-06-14fmt.Print*: reimplement to switch on type first.Rob Pike1-89/+6
This shortens, simplifies and regularizes the code significantly. (Improvements to reflect could make another step.) Passes all.bash. One semantic change occurs: The String() method changes behavior. It used to run only for string formats such as %s and %q. Instead, it now runs whenever the item has the method and the result is then processed by the format as a string. Besides the regularization, this has three effects: 1) width is honored for String() items 2) %x works for String() items 3) implementations of String that merely recur will recur forever Regarding point 3, example from the updated documentation: type X int func (x X) String() string { return Sprintf("%d", x) } should cast the value before recurring: func (x X) String() string { return Sprintf("%d", int(x)) } R=rsc CC=golang-dev http://codereview.appspot.com/1613045

2010-04-12fmt format verb %b bugAndrei Vieru1-7/+4
fmt.Printf("%b", int8(-1)) prints 64 ones instead of 8. This happens only for signed integers (int8, in16 and int32). I guess it's because of the way the conversion between integer types works. From go spec: "Conversions between integer types. If the value is a signed quantity, it is sign extended to implicit infinite precision ....". And there are several conversions to int64 and uint64 in the fmt package. This pathch solves only half of the problem. On a 32 bit system, an fmt.Printf("%b", int(-1)) should still print 64 ones.

2010-02-28Count utf8 runes, not bytes when determining string width. NoteStephen Ma1-1/+2
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>
2009-12-15 1) Change default gofmt default settings forRobert Griesemer1-138/+138
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 Pike1-214/+184
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.
