SYNOPSIS

portfix original

DESCRIPTION

portfix is a wrapper. It consecutively runs:

  1. dupe original
  2. <editor> original
  3. genpatch original

If PORTEDITOR is defined in the environment then that program will be used to edit [original] file. If PORTEDITOR is not defined but EDITOR is defined, then the EDITOR program will be invoked. If neither variable is defined in the environment, then vi(1) will be invoked for the edit step.

portfix should be launched when the current working directory is equal to the port’s WRKSRC, and [original] should be a relative path to file that needs a patch. Assuming changes are saved after the editor appears, a patch file will be automatically generated in the proper diff format with the standard "make makepatch" naming convention. It only needs to be moved to the port’s "files" directory to be used.

If portfix is launched outside of the port’s WRKSRC, then diff output will still be generated, but it will be sent to stdout rather than to a file. This will also occur when the port is located outside of the standard tree.

ERRORS

The script will abort if the number of arguments does not equal one, or if the one argument is not an existing regular file.

If the editor is closed without making changes, no patch will be created. However, the duplicated file will exist. If the script is run again, it will detect the duplicate and create a second duplicate with the .intermediate extension. See genpatch(1) for more information.

ENVIRONMENT

PORTEDITOR
  First priority editor to use for modifying file to be patched
EDITOR Second priority editor to use for modifying file to be patched

SEE ALSO

dupe(1), genpatch(1)

HISTORY

This script was inspired by pkgsrc’s pkgdiff suite although it works a bit differently. It was written by
.An John Marino Aq Mt marino@freebsd.org and used for a couple of years on DragonFly’s DPorts before being formally imported into FreeBSD Ports Collection.
