MacOS – Gnu-info page exists, but is visible from neither emacs nor terminal

emacshomebrewmacosopen sourceterminal

After installing gnuplot on Lion using 'brew gnuplot', the gnuplot info page appears at /usr/local/Cellar/gnuplot/4.4.3/share/info/gnuplot.info

But in the info index page (M-x info) in emacs, I see no gnuplot entry.

How can one point the "info system" (for emacs especially) to the newly installed gnuplot info page? If I missed something during brewing that would have connected the gnuplot info to the master info page, please point it out. If there is a direct way of reading the gnuplot page (again, through emacs) without going through the master index, please also mention it.

Is the info file symlinked in /usr/local/share/info? If not, a simple

ln -s /usr/local/Cellar/gnuplot/4.4.3/share/info/gnuplot.info /usr/local/share/info/

should solve the problem.

If not, look at the value of Info-directory-list in Emacs (C-h v). If "/usr/local/share/info" isn't included there, you can add it with

(push "/usr/local/share/info" Info-directory-list)

in the *scratch* buffer (and in .emacs of course).

Copy song info from mp3 file to aac file from terminal

I prefer the mutagen Python library for tag editing, since it has good support for a wide variety of formats with a consistent interface. Here’s a script for copying the metadata of a file:

import mutagen
import mutagen.easyid3
old = mutagen.easyid3.EasyID3('example.mp3') 
new = mutagen.File('example.m4a') 
new.update(old)
new.save()

You can open any file with mutagen.File, but that gives you raw access to the coded ID3 tags like 'TPE1', instead of human-readable tags like 'artist', so EasyID3 is used instead.

“brew link node” creates/removes different number of symlinks when repeated

Do you have several versions of Node installed via homebrew? Every time it updates node homebrew puts the newest version alongside the old one and then updates the symlinks to the newest version. Running the brew cleanup should reduce that up a bit for you.
