Run without write access to source directory

[phemmer]

New user to repomix, and was testing with the docker image. It appears the application cannot run without write access to the source directory, even if the output file is specified to go elsewhere.

For example:

# mkdir /tmp/source

# echo hello > /tmp/source/world

# mkdir /tmp/out

# podman run -v /tmp/source:/app:ro -v /tmp/out:/out -t --rm ghcr.io/yamadashy/repomix -o /out/repomix                   

📦 Repomix v0.2.29

If you take the :ro flag off the volume mount it works, even though output has been redirected somewhere else. I'm not sure if it's trying to use the source directory as a temporary working directory or what. But IMHO it shouldn't be putting anything in it. Any temporary files should either go in the directory of the output file, $XDG_RUNTIME_DIR, or /tmp/.

Might also help if the error message would a little clearer. It took me a minute to figure out what the issue was, when the directory was there, readable, and not being used for output.
