xontrib-hist-navigator

Fish-shell like prevd and nextd for xonsh with keyboard shortcuts

Usage

• install using pip

pip install xontrib-hist-navigator

• or xpip (that is installed alongside xonsh)

xpip install xontrib-hist-navigator

• add to list of xontribs loaded.

xontrib load hist_navigator

Overview

• it keeps track of cd usage per session
• Shortcuts

Traversal behavior

By default, all cd history is kept. Let's look at an example. Let's open a new shell:

❯

Now when we change the directory, it's added to the history along with the previous directory where we were (the user's home directory):

❯ cd BASE
❯ listd
['~', '~/BASE']

Let's descend further down:

❯ cd sub
❯ listd
['~', '~/BASE', '~/BASE/sub']

So far, so obvious. Now, when we use prevd, you'll see that the history stays intact:

❯ prevd
❯ pwd
~/BASE
❯ listd
['~', '~/BASE', '~/BASE/sub']

This allows you to use nextd to go back and forth:

❯ nextd
❯ pwd
~/BASE/sub
❯ listd
['~', '~/BASE', '~/BASE/sub']
❯ prevd
❯ pwd
~/BASE
❯ listd
['~', '~/BASE', '~/BASE/sub']

Now, if you change the directory entirely after a prevd, the entire previous history is still kept:

❯ pwd
~/BASE
❯ listd
['~', '~/BASE', '~/BASE/sub']
❯ cd /tmp
❯ listd
['~', '~/BASE', '~/BASE/sub', '/tmp']

This means that issuing prevd now will actually return to ~/BASE/sub and not to ~/BASE which was the last seen previous directory. This is by design to allow you to quickly traverse previously visited directories using keyboard shortcuts.

If you would rather have the history truncated, so that prevd always takes you to the directory you were in just before, set the following environment variable in your xonshrc:

$XONTRIB_HIST_NAVIGATOR_TRUNCATE="true"

In this case the last example would behave differently:

❯ pwd
~/BASE
❯ listd
['~', '~/BASE', '~/BASE/sub']
❯ cd /tmp
❯ listd
['~', '~/BASE', '/tmp']

As you can see ~/BASE/sub was dropped from history because it wasn't the last visited directory at the time of changing the directory to /tmp.
