The emacs.stackexchange beta has only just started and interesting
topics have already begun to pop up. Partially to share snippets I
find nifty, and partially to help promote the beta, I’ll be posting
here questions and answers I find engaging.
I’m kicking off this series with a question of my own, answered by none
other than Sebastian Wiesner. (Did you know he has a blog)? The beta
is still private, so you might not be able to visit the links above,
but I’ll summ it up here.
Question
For a while now I’ve noticed my dired patterns are somewhat
predictable.
Whenever I visit the directory of one of my papers, I go straight to
the “master.tex” file.
When I open the root of an android project, it’s almost always to
visit the the “AndroidManifest.xml”.
Finally, when I go to a directory where I’m developing an emacs
package, 80% of the time I’m headed for the package's main source
file.
See the pattern? For all these directories, the first file I visit is
very predictable, so I wanted dired to focus that file automatically
for me. So I would only need to hit RET—lazyness
to the extreme.
Solution
Sebastian looks into the save-place package’s source code, and finds
out about dired-initial-position-hook, which is run exactly when we
need. Visiting a file whose name we already know is then a trivial
matter. Note I’ve edited his code a bit.
Making dired focus the source file of elisp packages is tad bit
tricker because the file’s name is not fixed. The solution I found
(still borrowing some of Wiesner’s code) was to look for a file whose
name matched the current directory’s name, and if it that doesn’t
exist just focus any “.el” file. This works well for me because my
directory structure typically looks like “~/Git/paradox/paradox.el”.
Auto-focus a Relevant File in Dired Buffers
