Add link to hstow

[spwhitton]

Hello,

Thanks for this script. I recently implemented something similar, except it truly has no dependencies other than POSIX sh. Perhaps you'd consider adding a link to my script to the README?

Looks great! I'm pretty close to archiving stowsh as I find shell pretty much unmaintanable, and I'm happy to see someone else working on this use case!

Couple of questions:

• why do you link the package to a directory under ~/.STOW, and then link to that link? Why the indirection? Why not just link to the package?
• assuming there's a good reason for the previous question, would you consider changing ~/.STOW to something more consistent with the XDG spec, e.g. ~/local/share/stow?
• I couldn't get unstow to work:

$ ./hstow stow package/
$ ./hstow unstow package/
cut: [-bcf] list: values may not include zero

* why do you link the package to a directory under `~/.STOW`, and then link to that link? Why the indirection? Why not just link to the package?

I was previously using a wrapper for GNU Stow, written by the GNU Stow maintainer, which arranged things this way. By using the same scheme I don't have to try to migrate my symlinks on all the hosts I've got my dotfiles checked out on. Independently, I like how it makes it easy to identify the symlinks created by hstow, and means the unstow() routine can be simple.

* assuming there's a good reason for the previous question, would you consider changing `~/.STOW` to something more consistent with the XDG spec, e.g. `~/local/share/stow`?

It's unfortunate an XDG-compatible location wasn't chosen originally. But unfortunately I can't change it now without losing the two advantages noted above.

* I couldn't get `unstow` to work:

$ ./hstow stow package/
$ ./hstow unstow package/
cut: [-bcf] list: values may not include zero

Strange, can you 'set -x' for more info, please?

Hello, Thanks. Does it fix it if you replace the dir_pat line with this: dir_pat="^.$(echo $DIR | cut -c$(echo $HOME | wc -m | tr -d ' ')-)/"

++ grep -v '^./tmp/package/'

... and then nothing. The process is stuck. No output and I have to ctrl-c to get back a prompt.

Hello Mike, Thank you for your reply. It confirms my previous fix is correct, at least, even if you have now stumbled upon another problem. I'm afraid I have no idea why it would get stuck there, and I don't have access to an OS X machine myself to look into it further. If you do figure it out, please let me know.
