title: An example of Forth to \LaTeX

% This is a comment.

section: Overview:

Fex is a forth to \LaTeX converter. It uses a simple syntax with the
ability to use \LaTeX commands or some forth commands.

section: Base commands:

  This is a normal text.

  _( This is an underlined text. )_

  *( This is a bold text. )*

  /( This is an italic text. )/

  *( _( This is a bold and underlined text. )_ )*

 left( This text is on the left. )left

  center( This is a centered text. )center

  right( This text is on the right. )right

  frame( This text has a frame on it. )frame

  This command put the 'foo' word in the margin.        margin: foo

section: Numbering:

enumerate(
  => This is the first item.
  => This is the second item.
  => This is the third item.

    enumerate(
      => This is the first subitem
      => This is the second subitem
      => This is the third subitem
    )enumerate

  => This is the fourth item.
)enumerate


section: Picture:

  This is a picture: image: smiley.eps, scale=0.2

section: Tabulars:

tabular( 4 )(
  Col1 | Col2 | Col3 | Col4
  --
  Pouf | Paf | Pif | Plop plop
  --
  Toto | Azer | Poipoi | Pouf
)tabular

section: Boxes:

box( 5cm )( This is a box with long lines truncated ...... .......... ..........
.... ........ ........... )box
hspace= 4cm
box( 5cm )( This is a second box with long lines truncated ........ ..... ........
.... ....... ........ ......... )box


section: Personal commands and \LaTeX commands:

This is a formula: $ z^2 = 2.x^3 + 3.y^3 + \sqrt{\frac{x}{y}}$

Commands for simplified input:
$ U_ pouf = Z_ toto \times I_ titi $


A predefined header: \\

(Name-Header) \\

A question

(answer->visible)
->answer: toto

Another question

->answer: pouf

Another question

(answer->invisible)
->answer: paf paf

(double-answer)

And a last question

->answer: klm poi

margin: 3~points

section: Personal commands in Forth:

This command is definied in Forth at the begining of the file: my-command

This one too:

center( my-second-command )center

Those commands are executed directly from the forth code embeded in the document:

forth( 5 5 + . cr
  : test1   ." 2 + 2 = " 2 2 + . cr ;
  test1

  : test2   6 1 do ." $" I . ." ^2 = " I I * . ." $ ; " loop ;
  test2
)forth
