Thanks for the link. I am not a good lisp hacker, so I cannot be sure of this, but I suppose Bastien did not notice the last argument 'a'. Indeed, the function is defined as: --8<---------------cut here---------------start------------->8--- (get-text-property POSITION PROP &optional OBJECT) Return the value of POSITION's property PROP, in OBJECT. OBJECT should be a buffer or a string; if omitted or nil, it defaults to the current buffer. If POSITION is at the end of OBJECT, the value is nil. --8<---------------cut here---------------end--------------->8--- Then, the POSITION argument is the position in OBJECT to look for the property. Therefore, the use of a function related to the current buffer (like point-min) seems to strongly assume that OBJECT is the current buffer (or nil). In that case, OBJECT is not the current buffer but a string called 'a'. Thus, IIUC, it makes no sense to use OBJECT=a and POSITION=(point-min). -- Konubinix GPG Key : 7439106A Fingerprint: 5993 BE7A DA65 E2D9 06CE 5C36 75D2 3CED 7439 106A [-- Attachment #2: Type: application/pgp-signature, Size: 472 bytes --]
