Subject: bug#13439: 24.4.50; improvement of describe-variable/pp
Date: Tue, 15 Jan 2013 05:51:52 +0900 [thread overview]
Message-ID: <ACCDF298FAF962shigeru.fukaya@gmail.com> (raw)
Hi,
`describe-variable' is very slow for large objects.
It is mainly because `pp' used in it is slow on that case
(comments say `take an age').
When `pp' is to a buffer, in other words, output stream is a buffer,
current code is as follows:
1) Output the object to a temporary buffer.
2) Convert the buffer contents to a string.
3) Insert the string to an output buffer.
If the insertion is directry from the temporary buffer without
conversion, things go better dramatically.
Regards,
Shigeru
