help configuring diff & merge to use meld

[laur89]

Any meld users here willing to share their configs? I've this in ~/.config/chezmoi/chezmoi.toml:

[diff]
    # do not show scripts that would be run w/ diff cmd:
    exclude = ["scripts"]
    command = "meld"
    args = ["--diff",
        "{{ .Destination }}",
        "{{ .Target }}",
    ]
[merge]
    command = "meld"
    args = ["--diff",
        "{{ .Destination }}",
        "{{ .Source }}",
        "{{ .Target }}",
    ]

which mostly works, but every now and then it fails:

$ chezmoi apply --dry-run   # same error also with the diff command
.local has changed since chezmoi last wrote it?
Usage: 
  meld                              Start with an empty window
  meld <file|folder>                Start a version control comparison
  meld <file> <file> [<file>]       Start a 2- or 3-way file comparison
  meld <folder> <folder> [<folder>] Start a 2- or 3-way folder comparison

Error: Cannot compare a mixture of files and directories

chezmoi: .local: exit status 2

Any pointers? Also open for other diff tool suggestions on linux.
