'''browse the repository in a graphical way
|
|
|
|
|
|
The hgk extension allows browsing the history of a repository in a
|
|
|
graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
|
|
|
distributed with Mercurial.)
|
|
|
|
|
|
hgk consists of two parts: a Tcl script that does the displaying and
|
|
|
querying of information, and an extension to Mercurial named hgk.py,
|
|
|
which provides hooks for hgk to get information. hgk can be found in
|
|
|
the contrib directory, and the extension is shipped in the hgext
|
|
|
repository, and needs to be enabled.
|
|
|
|
|
|
The :hg:`view` command will launch the hgk Tcl script. For this command
|
|
|
to work, hgk must be in your search path. Alternately, you can specify
|
|
|
the path to hgk in your configuration file::
|
|
|
|
|
|
[hgk]
|
|
|
path = /location/of/hgk
|
|
|
|
|
|
hgk can make use of the extdiff extension to visualize revisions.
|
|
|
Assuming you had already configured extdiff vdiff command, just add::
|
|
|
|
|
|
[hgk]
|
|
|
vdiff=vdiff
|
|
|
|
|
|
Revisions context menu will now display additional entries to fire
|
|
|
vdiff on hovered and selected revisions.
