| 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. | |
