NAME

Math::Symbolic::Custom::DefaultDumpers - Default Math::Symbolic output routines

SYNOPSIS

  use Math::Symbolic qw/parse_from_string/;
  $term = parse_from_string(...);
  print $term->to_latex(...);

DESCRIPTION

This is a class of default output routines for Math::Symbolic trees. Likewise, Math::Symbolic::Custom::DefaultTests defines default tree testing routines and Math::Symbolic::Custom::DefaultMods has default tree modification methods. For details on how the custom method delegation model works, please have a look at the Math::Symbolic::Custom and Math::Symbolic::Custom::Base classes.

EXPORT

Please see the docs for Math::Symbolic::Custom::Base for details, but you should not try to use the standard Exporter semantics with this class.

SUBROUTINES

to_latex

This method is highly experimental. Use with care. It returns a LaTeX representation of the Math::Symbolic tree it is called on. The LaTeX is meant to be included in a LaTeX source document.

The method uses named parameter passing style. Valid parameters are:

implicit_multiplication

Used to turn off the 'x' operators for all multiplications. Defaults to false, that is, the multiplication operators are present.

no_fractions

Use '%' division operator instead of fractions. Defaults to false, that is, use fractions.

exclude_signature

By default, the method includes all variables' signatures in parenthesis if there is one. Set this to true to omit variable signatures.

replace_default_greek

By default, all variable names are outputted as LaTeX in a way that makes them show up exactly as they did in your code. If you set this option to true, Math::Symbolic will try to replace as many greek character names with the appropriates symbols as possible.

Valid LaTeX symbols that are matched are:

  Lower case letters:
    alpha, beta, gamma, delta, epsilon, zeta, eta, theta,
    iota, kappa, lambda, mu, nu, xi, pi, rho, sigma,
    tau, upsilon, phi, chi, psi, omega
  
  Variant forms of small letters:
    varepsilon, vartheta, varpi, varrho, varsigma, varphi
  
  Upper case letters:
    Gamma, Delta, Theta, Lambda, Xi, Pi, Sigma, Upsilon, Phi,
    Psi, Omega

variable_mappings

Because not all variable names come out as you might want them to, you may use the 'variable_mappings' option to replace variable names in the output LaTeX stream with custom LaTeX. For example, the variable x_i should probably indicate an 'x' with a subscripted i. The argument to variable_mappings needs to be a hash reference which contains variable name / LaTeX mapping pairs.

If a variable is replaced in the above fashion, other options that modify the outcome of the conversion of variable names to LaTeX are ignored.
