Countless build tools and shell scripts use ANSI escape codes to colorize their
output. This provides impressive improvements to readability when running from a
terminal that supports them, but tends to cause a catastrophic mess anywhere
else. Emacs’ compilation buffer is one such place. It doesn’t support ANSI
colors by default, but that’s very easy to fix.

Are you a Chromebook user or thinking of becoming one? Are you a die-hard
Emacser who needs to see it run even in your browser for no good reason (no
judgement)? Either way, Emacs has you covered. Thanks to the efforts of Pete
Williamson (and friends), there is now an Emacs port for Chromebook and Chrome.

Admittedly, I’m a very late passenger in this boat — only after 4 years of
using Emacs did I decide to try a project manager. Nowadays I can’t even
remember my daily workflow without Projectile. This package mostly stays out of
your way, and provides a series of useful commands for dealing with a project
(which are aware of a lot of languages out-of-the-box). As usual, you can find
details in the readme, and we’ll jump straight into useful configurations.

As Android phones rise in power, bluetooth keyboards become cheaper, and your
addiction to Emacs grows, it’s only natural that you start thinking of combining
the three. Fortunately for you, it’s not as hard as it used to be. In fact, it’s
perfectly possible to reproduce (most of) your desktop config, if you know how
to get past a few obstacles.

One of the things I like most in CIDER is how evaluation results are displayed
by inline overlays. And yet, for some reason, it’s taken me almost a year to
transfer that to Elisp.

Have you ever stopped to think about why isearch leaves point at the end of the
match? It does make some intuitive sense to leave you after the characters you
have just typed, but that doesn’t make it the most practical behaviour.

I’ve said before that clj-refactor is a magical package, and you wouldn’t catch
me bad-mouthing it in a million release cycles, but it’s impossible to please
everybody.
[...]
CIDER 0.11.0 has been out for less than week and already the snapshots are
getting new features. This one comes from a gentleman called Chris Perkins. It
provides an easy way to automatically skip some breakpoints during evaluation,
and it even comes with 300 brand new lines of tests.
[...]
As you may remember, one of the commands I like the most from the clj-refactor
package are the ones that thread and unwind Clojure code forms for you. Now that
Emacs is also getting built-in threading macros, I figured the best way to give
them a fair chance in life is to also make them pretty convenient to use.
[...]
One of my personal favorite new additions to Emacs 25 is, in fact, completely
invisible to most users. The new macros if-let and when-let, although simple
in purpose, are a delight to use and are frequently finding their way into my
code. The other two additions, thread-first and thread-last, are a bit more
specific, and take a bit getting-used-to if you’ve never seen them before.
[...]
Another library by the productive Nicolas Petton. map.el is a cousin to
seq.el (remember?), but instead of manipulating plain sequences, it
manipulates map-like collections (also known as dictionaries).

In the upcoming version, EWW is getting a number of small improvements. This web
browser, written by Lars Ingebrigtsen, is something of a new kid on the block,
as it just came to life at the very end of the Emacs 24 cycle. Although it’s
hard, if not impossible, to reliably render HTML inside an editor that’s 100%
line-based, EWW tends to find a reasonable compromise and deserves at least a
short post to cherish new features.

Since last week’s post was about Unicode characters, it makes sense to continue
that trend today. This feature might go unnoticed by a lot of people who live in
an ASCII world, but it will probably jump out at everyone else at one point or
another. The name, if a bit odd, is “character-folding search”.
[...]
Don’t be fooled by the apparent simplicity of this feature. Its implementation
has been the most controversial addition to the upcoming Emacs release — to a
comical degree. This post, however, is not about arguments or implementation,
it’s about Emacs 25. And this little nugget is all set for the next release.

Isearch is one of Emacs’ most useful (and probably most used) features. Getting
in the habit of quickly hitting C-s followed by 2–4 letters will forever
change the way you navigate buffers, and adding it to your repertoire is a
tremendous productivity improvement. What, then, could we possibly improve on
such a phenomenal command?
