bug#61691: (wrong-type-argument stringp nil) error when indenting some C code in c-ts-mode

[Daniel Martín]

Tags: patch


Given the following code in c-ts-mode:

int
foo ()
{
  int c;
  if (!CHAR_VALID_P (c))
    /* This is a comment.  */
    c = 'a';

  return c;
}

If point is in line "c = 'a'" and you press TAB, a (wrong-type-argument
stringp nil) error is thrown.

The attached patch fixes the problem by checking the return value of
(treesit-node-field-name node) before passing the result to
string-match-p.
