Styling & constants

Appearance settings across five tabs, and up to 100 app-wide constants available in every sheet.

Numlex’s settings are organized into five native tabs with native switches. Nothing here is cloud-synced — every preference is stored on your Mac.

The five settings tabs

Tab	What it controls
General	App-level behavior
Editing	Input helpers and editing behavior
Numbers	Regional number format presets and toggles (see Number formats)
Constants	App-wide constant definitions
Styling	Appearance: theme, fonts, role colors

Appearance

On the Styling tab you can:

Choose Light or Dark for the whole app (the default is Dark).
Tune font size and font design.
Adjust the role colors used for syntax tinting (numbers, variables, units, money, and so on).
Set decimal places, input helpers, and line-number visibility.
Choose the interface language and the currency display style.
Hide the sidebar button once collapsed — reopen it any time with ⌃⌘S (Control-Command-S) or View → Toggle Sidebar.

App-wide constants

Define up to 100 app-wide constants that are available in every sheet and resolved live through the same strict engine — function arguments included:

PI = 3.141592653589793
Sales Tax = 20%
Side = sqrt(4)

Side × 2            4
1000 × PI           3,141.59…

Because constants are resolved live, changing a constant updates every sheet that uses it.

Note: constants are not embedded into .nlx exports. If you export a sheet that uses a constant and open it on another machine, that machine needs a matching constant defined. See Sheets & files.
