2010-06-02 Optimization to regexp _CharClass: keep track of overall range ofKyle Consalus2-10/+48
charclass to avoid unnecessarily iterating over ranges. Also, use the fact that IntVector is an []int to avoid method calls. On my machine, this brings us from ~27500 ns/op to ~17500 ns/op in the benchmark I've added (it is also faster in the case where a range check doesn't help, added a benchmark for this too.) I'd also like to propose that "[]", and "[^]" be disallowed. They aren't useful as far as I can tell, they aren't widely supported, and they make reasoning about character classes a bit more complicated.

2009-12-24Add query to find number of subexpressions.Peter Froehlich2-0/+31
This was convenient for me to have without being forced to parse the regexp myself. I'd understand if it's not really wanted, but I also think that some meta information about compiled regexps would be fine.

2009-12-151) Change default gofmt default settings forRobert Griesemer2-549/+549
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 4th set of files.

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.

2009-11-19two easy optimizations for regexp:Rob Pike2-13/+83
1) if char class contains a single character, make it a single character. (this is used to quote, e.g. [.] rather than \. 2) if regexp begins with ordinary text substring, use plain string match to start engine R=rsc CC=golang-dev http://codereview.appspot.com/157095
