Hullo Olivier,

I was going to apply the patch below to fix the password-store 
package, but Maxime just submitted another version which I prefer. 
I'd rather not provide two trees in Guix.

After some consideration, I think it's an interesting feature. 
Something like this is long overdue.

I don't know if this approach is the right one, but I'll 
begrudgingly settle for JSON if it finally catches on…

They can be fixed, or better yet rewritten.  tree(1) is not tr(1). 
‘Some lazy idiot could parse this with bash’ != ‘frozen API which 
upstream can never improve’.  Really.

…uh, I'm describing myself there, by the way ;-)  I feel quite 
seen.

Not that they needed to, but upstream even bumped the major 
revision along with this change.

Fully agree!  I wasted too much time trying to track it down 
myself.  I blame password-store's spaghetto of redirection more 
than tree.

Kind regards,

I'm fine with both solutions.  In the end, password-store is not broken,
only its test suite.

Just to be clear that the JSON is still there with the switch -J.  I
just think that using some random file descriptor like this is a path to
break many tools.  Any program that open a file and try to do a popen(3)
with "tree" for its output will get bitten by it.  It's not like if
`stddata` is some common knowledge outside of the PowerShell world.

Happy to know I'm not the only one who spend way too much time on this ^^

FWIW I had never heard of it.  I'll admit it's not a good start in 
life.

Kind regards,
