Powerful Pipelines

Text pipelines are intuitive and powerful. However, if your data have inherently complex structures, passing them through the pipeline often requires a lot of ad-hoc, hard-to-maintain text processing code.

Pipelines in Elvish can carry structured data, not just text. You can stream lists, maps and even functions through the pipeline.

~> if $true { echo good } else { echo bad }               
~> for x [lorem ipsum] {
echo $x.pdf
~> try {
fail 'bad error'
} except e {
echo error $e
} else {
echo ok
error ?(fail 'bad error')
Intuitive Control Structures

If you know programming, you probably already know how if looks in C. So why learn another syntax?

Control structures in Elvish have an intuitive C-like syntax.

Directory History

Is cd /a/long/nested/directory the first thing you do every day? Struggling to remember where your logs and configurations?

Elvish remembers where you have been. Press Ctrl-L and search, like in a browser.

Command History

Want to find the magical ffmpeg command that you used to transcode a video file two months ago?

Just dig through your command history with Ctrl-R. Same key, more useful.

(To be fair, you can do this in bash with history | grep ffmpeg, but it's far fewer keystrokes in Elvish :)

Built-in File Manager

Power of the shell or convenience of a file manager?

Choose both. Press Ctrl-N to quickly navigate directories and preview files, with full shell power.
