Graphomata – Bolttog

Bolttog (Esolang)

Bolttog is a variant of Gottlob that supports and prioritizes right-to-left (RTL) languages.

Changes

The general layout is RTL.
Numbers are written LTR (left-to-right).
Math expressions are written RTL* if they use at least one letter or digit of an RTL alphabet, otherwise LTR.
Utility functions and literal judgments are available under both their original names and localized ones. Localized versions use the local conventions for I/O.
No typographical conventions

* As used in children's books, preferrably with spacing and appropriate operators. Notable exception: unary operators, which are parenthesized, as are negative numbers. Function definitions and calls are regarded as math expressions.

Examples

	Example 1	Example 2
Program	input(»Fahrenheit = ?«) ≡ f ─┤ output(»Celsius = «) outputLine(c(f)) :c(f) 5*(f−32)/9	פ ≡ קלט(„פרנהייט = ?”) ─┤ פלט(„צלזיוס = ”) פלטשורה(צ(פ)) :צ(פ) 9 ÷ (פ − 32) × 5	← reverse order
Example interaction	Fahrenheit = ? -4 < Celsius = -20	? = פרנהייט (-4) < (-20) = צלזיוס	← localized ← I/O
