gdiff¶
vb diff|gdiff [OPTIONS] [FILE1] [FILE2 ...]
Description¶
Show the difference between the current version of each of the FILEs specified (as they exist on disk) and that same file as it was checked- out. Or if the FILE arguments are omitted, show all unsaved changes currently in the working check-out. The gdiff variant means to to use a GUI diff.
The default output format is a unified patch (the same as the
output of diff -u on most unix systems). Many alternative formats
are available. A few of the more useful alternatives:
--tk Pop up a Tcl/Tk-based GUI to show the diff
--by Show a side-by-side diff in the default web browser
-b Show a linear diff in the default web browser
-y Show a text side-by-side diff
--webpage Format output as HTML
--webpage -y HTML output in the side-by-side format
The --from VERSION option is used to specify the source check-in
for the diff operation. If not specified, the source check-in is the
base check-in for the current check-out. Similarly, the --to VERSION
option specifies the check-in from which the second version of the file
or files is taken. If there is no --to option then the (possibly edited)
files in the current check-out are used. The --checkin VERSION option
shows the changes made by check-in VERSION relative to its primary parent.
The --branch BRANCHNAME shows all the changes on the branch BRANCHNAME.
With the --from VERSION option, if VERSION is actually a directory name
(not a tag or check-in hash) then the files under that directory are used
as the baseline for the diff.
The -i command-line option forces the use of VisionByte’s own internal
diff logic rather than any external diff program that might be configured
using the setting command. If no external diff program is configured,
then the -i option is a no-op. The -i option converts gdiff into
diff.
The --diff-binary option enables or disables the inclusion of binary files
when using an external diff program.
The --binary option causes files matching the glob PATTERN to be treated
as binary when considering if they should be used with the external diff
program. This option overrides the binary-glob setting.
These command show differences between managed files. Use the vb xdiff command to see differences in unmanaged files.
