/*
|
Fix finds Go programs that use old APIs and rewrites them to use
|
newer ones. After you update to a new Go release, fix helps make
|
the necessary changes to your programs.
|
|
Usage:
|
go tool fix [-r name,...] [path ...]
|
|
Without an explicit path, fix reads standard input and writes the
|
result to standard output.
|
|
If the named path is a file, fix rewrites the named files in place.
|
If the named path is a directory, fix rewrites all .go files in that
|
directory tree. When fix rewrites a file, it prints a line to standard
|
error giving the name of the file and the rewrite applied.
|
|
If the -diff flag is set, no files are rewritten. Instead fix prints
|
the differences a rewrite would introduce.
|
|
The -r flag restricts the set of rewrites considered to those in the
|
named list. By default fix considers all known rewrites. Fix's
|
rewrites are idempotent, so that it is safe to apply fix to updated
|
or partially updated code even without using the -r flag.
|
|
Fix prints the full list of fixes it can apply in its help output;
|
to see them, run go tool fix -help.
|
|
Fix does not make backup copies of the files that it edits.
|
Instead, use a version control system's ``diff'' functionality to inspect
|
the changes that fix makes before committing them.
