Subject: bug#65913: with-help-window arranges for 'inhibit-read-only' to be set to 't'
Date: Wed, 13 Sep 2023 10:41:01 +0000 [thread overview]
Message-ID: <SiX8VM8yTLl5VtNt_JvgMarZQ_LzxiqiJTw2Klf9iUZITBSWmyz423YtZ8ISoQg2iv8SZILXCAWrv5HkOqco3dmz2X_sLX8iyEd_Qm8LxpQ=@protonmail.com> (raw)
Any time one wants to write (insert) into a read-only buffer (e.g. *help*),
one has to make it writable. Doesn't matter when that time is. If it's
read-only you need to make it writable to write into it.
Reading the source for 'with-help-window', it arranges for 'inhibit-read-only'
to be set to 't' around the call to its body. Once the body finishes, that
temporary binding goes out of scope and read-only is in effect again.
The aforementioned resetting of 'inhibit-read-only' to 't' is an important
feature that should be included in the docstring for the function 'with-help-window'.
