default_cwd#

Sets the default current working directory used by the initial window.

The value is a string specifying the absolute path that should be used for the home directory. Using strings like ~ or ~username that are typically expanded by the shell is not supported. You can use wakterm.home_dir to explicitly refer to your home directory.

If wakterm start --cwd /some/path is used to specify the current working directory, that will take precedence.

Commands launched using SpawnCommand will use the cwd specified in the SpawnCommand, if any.

Panes/Tabs/Windows created after the first will generally try to resolve the current working directory of the current Pane, preferring a value set by OSC 7 and falling back to attempting to lookup the cwd of the current process group leader attached to a local Pane. If no cwd can be resolved, then the default_cwd will be used. If default_cwd is not specified, then the home directory of the user will be used.

On macOS and Linux, wakterm can attempt to resolve the process group leader and then attempt to resolve its current working directory. This is not guaranteed to succeed, and there are a number of potential edge cases (which is another reason for configuring your shell to use OSC 7 sequences).

On Windows, there isn't a process group leader concept, but wakterm will examine the process tree of the program that it started in the current pane and use some heuristics to determine an approximate equivalent.
