elpa-aggressive-indent - 1.9.0-3 main

electric-indent-mode is enough to keep your code nicely aligned when
all you do is type. However, once you start shifting blocks around,
transposing lines, or slurping and barfing sexps, indentation is
bound to go wrong.
.
aggressive-indent-mode is a minor mode that keeps your code always
indented. It reindents after every change, making it more reliable
than electric-indent-mode.
