Merging files in Sublime with Sublimerge via command line

Question

I'm trying to find a better merge file option and wanted to try out Sublime as of my work is done using it. so I installed Sublimerge and now am stuck. I know I can compare two already open files or compare via the Sidebar but what I want to do is fire it off via the command line so I can kick it off from our source control program like I can with every other merge tool I've seen. Does anyone know the command line format to do this?

N.B. - I've long since given up trying to use sublime to handle merges and instead switched to other tools to handle this. Therefore I've never felt I can accept any answer as I'm not checking them to see if they work in the way I'd want, or indeed whether they work at all.

Answer 1

 subl -n --wait "<LEFT>" "<RIGHT>" --command "sublimerge_diff_views {\"left_read_only\": true, \"right_read_only\": true}"

See "VCS Integration" for details.

Answer 2

As Nickolay already suggested, this is the whole directive you have to put in your ~/.gitconfig:

[merge]
    tool = sublimerge

[mergetool "sublimerge"]
    cmd = subl -n --wait \"$REMOTE\" \"$BASE\" \"$LOCAL\" \"$MERGED\" --command \"sublimerge_diff_views\"
    trustExitCode = false

[diff]
    tool = sublimerge

[difftool "sublimerge"]
    cmd = subl -n --wait \"$REMOTE\" \"$LOCAL\" --command \"sublimerge_diff_views {\\\"left_read_only\\\": true, \\\"right_read_only\\\": true}\"
