`find-func.el': interactive-form of `find-library' fails |
Date: |
Tue, 15 Jul 2008 15:46:55 +0100 |
To reproduce,
Visit a library file containing a `require' form, e.g.,
"M-x find-library RET yow RET". Search for a `require' form and
position point on its the opening left parenthesis. Invoke
`find-library' interactively with "M-x find-library RET".
Symptom
Instead of prompting for a library name, Emacs displays the error message
`Scan error: "Unbalanced parentheses", 1222, 1'.
Problem
The error is in the interactive form of `find-library' in `find-func.el'.
If point is over the opening left-paren of the `require' form then
`function-called-at-point' returns `require', whereupon `backward-up-list'
fails because point is not in a list.
Suggestions (for what they're worth :)
(a) Handle this special case in the `find-library' interactive form.
(b) Modify `function-called-at-point' to do what its docstring says.
(c) In the `find-function' interactive form, use `condtition-case'
to detect errors in computing the default.
