This CL makes gotype usable again. Removed -r (recursive) mode; use go/build to determine the correct set of Go files when processing a directory. The -v (verbose) mode now prints some basic stats (duration, number of files, lines, and lines/s). Thoroughly restructured the code. Applying gotype -v -a . to the go/types directory: 128.94141ms (40 files, 12008 lines, 93127 lines/s) On a 2.8 GHz Quad-Core Intel Xeon, 800 MHz DDR2 FB-DIMM, with go/types built with the (interal) debug flag set to false. There's still quite a bit of room for performance improvement in all parts of the code since no tuning has been done. R=golang-dev, adonovan CC=golang-dev https://golang.org/cl/19930043

/*
|
|
The gotype command does syntactic and semantic analysis of Go files
|
|
and packages like the front-end of a Go compiler. Errors are reported
|
|
if the analysis fails; otherwise gotype is quiet (unless -v is set).
|
|
|
|
Without a list of paths, gotype reads from standard input, which
|
|
must provide a single Go source file defining a complete package.
|
|
|
|
If a single path is specified that is a directory, gotype checks
|
|
the Go files in that directory; they must all belong to the same
|
|
package.
|
|
|
|
Otherwise, each path must be the filename of Go file belonging to
|
|
the same package.
|
|
|
|
Usage:
|
|
gotype [flags] [path...]
|
|
|
|
The flags are:
|
|
-a
|
|
use all (incl. _test.go) files when processing a directory
|
|
-e
|
|
report all errors (not just the first 10)
|
|
-v
|
|
verbose mode
|
|
|
|
Debugging flags:
|
|
-ast
|
|
print AST
|
|
-trace
|
|
print parse trace
|
|
-comments
|
|
parse comments (ignored unless -ast or -trace is provided)
|
|
|
|
Examples:
|
|
|
|
To check the files a.go, b.go, and c.go:
|
|
|
|
gotype a.go b.go c.go
|
|
|
|
To check an entire package in the directory dir and print the processed files:
|
|
|
|
gotype -v dir
|
|
|
|
To check an entire package including tests in the local directory:
|
|
|
|
gotype -a .
|
|
|
|
To verify the output of a pipe:
|
|
|
|
echo "package foo" | gotype
|
|
