View patch in external tool
Created originally on Bitbucket by psuter (Peter Suter)
TortoiseHG has options to specify external tools for three-way merging, visual diff viewing etc.
I use Beyond Compare 4 for these. Beyond Compare 4 can also visualize patch files. But TortoiseHG does not offer to view patches in an external tool. Unapplied MQ patches should have a context menu entry to view the patch in the configured external tool.
