More Details On find-file Vs. with-temp-buffer

Posted on 2011-12-21 by jcs

Yesterday, I mentioned that Xah Lee had a short post on dramatically differing run times for processing several files with find-file versus processing the same files using with-temp-buffer. His post was fairly short and didn’t have a lot of details. … Continue reading →

Timing Execution In Emacs

Posted on 2011-12-20 by jcs

Xah Lee has a short post on find-file vs. with-temp-buffer for loading a large number of files. The results were sort of surprising, at least to me, so you should take a look if you need to load several files … Continue reading →

In view of the fact that my last few posts have concentrated on the use of S-expressions to represent data—in particular, to represent log file entries—this seems like a good time to link to S-expressions: The most powerful data structure … Continue reading →

Filtering Log Files Stored As Lisp With Emacs

Posted on 2011-12-16 by jcs

Yesterday, I wrote about transforming log files stored as Lisp. Today, I want to continue that theme by considering how we can have the log file filter itself so that we can pick out records meeting certain criteria. I wasn’t … Continue reading →
