to_latex¶ ↑

Adds #to_latex to integers and strings. Works like html_safe in Rails, it escapes special characters as needed. Once converted, a string becomes a ToLatex::LatexString instance, with #latex? returning true, and never again will be escaped.

You can concatenate any escaped or not escaped string to an escaped one, they get properly escaped.

gem 'to_latex', '~>0.5.0'
require 'to_latex'

Strings and Integers are supported by default.

s = ''.to_latex
s << 'Hello 50% ' << '\LaTeX'.latex! << ' 50% Ruby!' # => "Hello 50\\% \\LaTeX 50\\% Ruby!"
s.latex? # => true
5.to_latex # => "5"
5.to_latex_math # => "\\ensuremath{5}"
