The browser-based version of Numbat is available at https://numbat.dev/.
The terminal allows you to perform a sequence of calculations.
You can use the arrow keys to browse through the command history.
The special identifiers
_ refer to the result of the last calculation. For example:
>>> 60 kW h / 150 kW = 0.4 h >>> ans -> minutes = 24 min
There is a set of special commands that only work in the web version:
|List all constants, units, and dimensions|
|Get more information about units and variables|
|View short help text|
|Reset state (clear constants, functions, units, …)|
In interactive command-line mode, you can use the following key bindings. Most importantly,
Tab for auto-completion, arrow keys and
Ctrl-R for browsing the command history, and
Ctrl-D for exiting the interactive session.
|Browse command history|
|Search command history|
|Clear the current line|
|Move cursor to the beginning of the line|
|Move cursor to the end of the line|
|Move cursor one word left/right|
|Remove text to the right of the cursor|
|Remove text to the left of the cursor|
To share the result of a calculation with someone else, you can just copy the URL from
your browers address bar. As you enter new lines in the terminal, your input will be
appended to the URL to build up something like
that you can just copy and share. To reset the state and clear the URL, use the
command (see above).
