I feel like pdocspath might be a better command here, even if it is a bit verbose. Luckily the prefix matching will then allow pdocs to work as well. Thoughts?

[dopcn]

have thought about this before. It seems to me the word docs path is a little ambiguous, maybe docs dir path is better but too long. Here use ppath is just easy to type in. will change to the name suggested.

Thought: have ppath capable of printing other paths other than docs, and have it take an argument to specify which specific path. Otherwise, perhaps ppath can just print the app root, and then it's easy for users to append Documents or any other subpath.

In other parts of Chisel, in addition to printing a value, we've copied it to the pasteboard. Would you mind adding that here?

[kastiglione]

@dopcn What do you think about having option flags to allow the desired directory to be opened in Terminal, or maybe Finder as well? For example ppath -t to open in Terminal. These don't need to be added to this pull request, but they'd be nice to add sooner or later.

[kastiglione]

Can you make constants for these numbers?

[kastiglione]

This could use evaluateObjectExpression() instead of evaluateExpressionValue(), which would make the NSString cast unnecessary.

[dopcn]

@kastiglione hi I tried evaluateObjectExpression() and evaluateExpression() but only get pointer value instead of string value so I keep using evaluateExpressionValue() and split the string output in the new implementation. Am I missing something?

[kastiglione]

@dopcn What do you think of the comments I made?

[dopcn]

@kastiglione sorry, back and working on it now...

[dopcn]

Update copy to the pasteboard before print

[kastiglione]

This could be echo -n to avoid the tr piece.

[dopcn]

I don't know why echo -n just doesn't work as os.system()'s parameter. The -n will be taken as part of pathString and copied into pasteboard

[kastiglione]

Seems /bin/sh doesn't handle -n like bash and zsh do. Oh well. Thanks for trying.

[kastiglione]

Thanks @dopcn, I'm happy to accept this. Before that, can you merge from master because there are now conflicts.

[kastiglione]

Thanks @dopcn!
