Just exercise debugindexdot
Create a short file history including a merge.
$ hg init t
$ cd t
$ echo a > a
$ hg ci -qAm t1 -d '0 0'
$ echo a >> a
$ hg ci -m t2 -d '1 0'
$ hg up -qC 0
$ echo b >> a
$ hg ci -m t3 -d '2 0'
created new head
$ HGMERGE=true hg merge -q
$ hg ci -m merge -d '3 0'
$ hg debugindexdot -c
digraph G {
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
$ hg debugindexdot -m
digraph G {
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
$ hg debugindexdot a
digraph G {
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
Include arbitrary graphviz statements
$ hg debugindexdot -c -i 'rankdir=BT' -i 'node [shape=box]'
digraph G {
rankdir=BT
node [shape=box]
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
Use a template for labels
$ hg debugindexdot -c -T '{desc}'
digraph G {
0 [label="t1"]
1 [label="t2"]
2 [label="t3"]
3 [label="merge"]
-1 -> 0
0 -> 1
0 -> 2
2 -> 3
1 -> 3
}
Templates only work with changelog
$ hg debugindexdot -m -T '{desc}'
abort: -T/--template is only supported for -c/--changelog
[255]
$ hg debugindexdot a -T '{desc}'
abort: -T/--template is only supported for -c/--changelog
[255]
Show a single rev
$ hg debugindexdot -c -r 0
digraph G {
0
}
$ hg debugindexdot -m -r 0
digraph G {
0
}
$ hg debugindexdot a -r 0
digraph G {
0
}
Show all revs explicitly
$ hg debugindexdot -c -r 0 -r 1 -r 2 -r 3
digraph G {
0
1
2
3
0 -> 1
0 -> 2
1 -> 3
2 -> 3
}
Show rev by node
$ hg debugindexdot -c -r $(hg log -r 0 -T '{node}')
digraph G {
0
}
Show sibling revs
$ hg debugindexdot -c -r 1 -r 2
digraph G {
1
2
}
Show a parent and child rev
$ hg debugindexdot -c -r 0 -r 1
digraph G {
0
1
0 -> 1
}
Show an ancestor and descendant rev
$ hg debugindexdot -c -r 0 -r 3
digraph G {
0
3
0 -> 3 [style=dashed]
}
Show common ancestors
$ hg debugindexdot -c -r 1 -r 2 --common
digraph G {
0 [style=filled]
1
2
0 -> 1
0 -> 2
}
Dashed edge from 0 to 3, even though it's already reachable via 0 -> 1 -> 3,
to represent 0 -> 2 -> 3.
$ hg debugindexdot -c -r 0 -r 1 -r 3
digraph G {
0
1
3
0 -> 1
1 -> 3
0 -> 3 [style=dashed]
}
$ cd ..
