Examples

import vcsn
exp = vcsn.context('lan, q').expression
e1 = exp('abc')
e1

$a \, b \, c$

e2 = exp('(<2>x)*')
e2

$\left( \left\langle 2 \right\rangle \,x\right)^{*}$

e1 | e2

$\left. a \, b \, c \middle| \left( \left\langle 2 \right\rangle \,x\right)^{*} \right.$

(e1 | e2).automaton()

e1.automaton() | e2.automaton()
