Lisp Error when `calibre-show-metadata`

[drcxd]

calibredb works fine for me, it opens the *calibre-search* buffer. However, when I try to invoke calibre-show-metadata, I get a lisp error:

Debugger entered--Lisp error: (wrong-type-argument listp #("284 Communicating Sequential Processes            ..." 0 4 (face calibredb-id-face id "284") 4 54 (face calibredb-title-face) 55 60 (face calibredb-format-face mouse-face calibredb-mouse-face help-echo "Filter with this format" keymap (keymap (mouse-1 . calibredb-format-mouse-1))) 61 72 (face calibredb-date-face mouse-face calibredb-mouse-face help-echo "Filter with this date" keymap (keymap (mouse-1 . calibredb-date-mouse-1))) 73 78 (author "Hoare" face calibredb-author-face mouse-face calibredb-mouse-face help-echo "Filter with this author: Hoare" keymap (keymap (mouse-1 . calibredb-author-mouse-1))) 79 88 (author " C.

I am using Emacs 30.0.50 on Windows, with built-in sqlite module. My calibredb package version is 20220612. I do have an external sqlite3 installed, and its version is 3.40.1. Any idea what leads to this problem?

[chenyanming]

Check if sql-sqlite-program is using the external sqlite3, for me, the value is /usr/bin/sqlite3. Built-in sqlite module is not supported yet.

[drcxd]

My sql-sqlite-program is c:/msys64/mingw64/bin/sqlite3.exe, which is also external. Do you think that building Emacs without sqlite module will fix this issue?

[drcxd]

I have compiled my Emacs again with no built-in sqlite module, but still get the same result. Also tested with Emacs release 28.2, still get the same error.

[drcxd]

Though I do not know emacs-lisp too much, I dig into the code a little bit. It seems that the problem has nothing to do with sqlite.

The echo area contains evaluating canditate in the debugger.

[chenyanming]

Oh, I see, just checked calibredb-show-metadata is buggy. It is not a useful feature by the way, it only prints out the metadata to Message buffer.

[chenyanming]

You can use calibredb-view insead.
