zotelo-set-collection: Wrong type argument: stringp, nil

[psamim]

Hi,

I just installed Zotelo. When I run zotelo-set-collection, I ger Wrong type argument: stringp, nil.

Thanks,

Can you provide a traceback? Which emacs is this?

Also you please do M-x zotelo-verbose, as it might give some hints of what is going wrong.

[psamim]

I am using Archlinux, Emacs 24.5.1, and Spacemacs 0.105.20. I did M-x zotelo-verbose and it displayed zotelo verbose 't', but I still has the same issue and no extra information is displayed.

I just found out that it happens only for one of my Zotero collections. If I choose *ALL* or any other collection, it works as expected, adds a file variable and updates the bib file.

The name of the collection which causes the problem is thesis, if it helps.

A suggestion - if you M-x set-variable debug-on-error t you will get a backtrace when this (or any Emacs) error fires, which will show where the problem is occurring.

Thanks for your help. I have this backtrace:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  propertize(nil name "thesis")
  zotelo-set-collection()
  call-interactively(zotelo-set-collection nil nil)
  command-execute(zotelo-set-collection)

Something is wrong with that particular collection. Could you please paste here the content of *moz-command-output* immediately after the error happens?

[psamim]

This is the content of *moz-command-output* buffer.

2 /Event-Oriented
3 /HTTP
6 /iot-context
5 /Radioactivity
4 /Refah
8 /thesis
1 /*groups*/HTTP/network-http
repl>

Is it about numbering? As It seems that there is no number 7, but there is 8, which causes problem.

[vspinu]

This is very strange. /thesis is just as anything else. Somehow that "8" is not picked by the regexp. Do you see it picked up by M-x regexp-builder with the this regexp "^\\([0-9]+\\) /\\(.*\\)$"?

It's defenitely something specific to your setup. I have pushed a small change that would throw an explicit error in such situations. I cannot do more without knowing what's the cause of it. Could you please try the latest version of zotelo?

BTW, I have removed hard-coded ido completion in zotelo. It's plain completing-read now. You can either use ido-ubiquitous, helm, ivy or set your own completion-read-function in zotelo buffers from now on.
