show-paren-mode is a minor-mode that highlights the bracket at point (be it
round, square, or curly) as well as its corresponding open/close counterpart. I
find it a must-have for Elisp and Clojure programming. On the other hand, when
editing Ruby code, it also highlights whole block delimiters, like
end, and all that must-haviness quickly turns into
Emacs’ customizable variables (a.k.a.,
defcustom) are allowed to specify a
:type parameter for setting its custom-type. The customize interface uses this
information to produce a sophisticated menu for the user to customize that
variable. However, a large fraction of users use
setq to directly edit custom
variables, and even some packages programmatically change the value of other
package’s custom variables. Ultimately, there are no guarantees that the value
in question matches the
:type specified in the variable.
As laptop touchpads seem to be steadily increasing in size, one unfortunate consequence is that it becomes increasingly harder to avoid touching them by accident while you type. Most systems have safeguards in place that disable the touchpad as you’re typing, but they always seem to fall short for me when it comes to Emacs. While in Emacs, my hands are permanently resting on the keyboard (and over the touchpad), so even if I stop typing for several seconds I don’t want the touchpad to reactivate. [...]
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. [...]
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
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
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-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.
