| /* |
| 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. |
