# = RedCloth - Textile for Ruby
|
|
#
|
|
# (c) 2003 why the lucky stiff (and his puppet organizations.)
|
|
#
|
|
# (see http://www.textism.com/tools/textile/ for Textile)
|
|
#
|
|
# Based on (and also inspired by) both:
|
|
#
|
|
# PyTextile: http://diveintomark.org/projects/textile/textile.py.txt
|
|
# Textism for PHP: http://www.textism.com/tools/textile/
|
|
#
|
|
#
|
|
# == What is Textile?
|
|
#
|
|
# Textile is a simple formatting style for text
|
|
# documents, loosely based on some HTML conventions.
|
|
#
|
|
# === Sample Textile Text
|
|
#
|
|
# h2. This is a title
|
|
#
|
|
# h3. This is a subhead
|
|
#
|
|
# This is a bit of paragraph.
|
|
#
|
|
# bq. This is a blockquote.
|
|
#
|
|
# === Writing Textile
|
|
#
|
|
# A Textile document consists of paragraphs. Paragraphs
|
|
# can be specially formatted by adding a small instruction
|
|
# to the beginning of the paragraph.
|
|
#
|
|
# h[n]. Header of size [n].
|
|
# bq. Blockquote.
|
|
# # Numeric list.
|
|
# * Bulleted list.
|
|
#
|
|
# === Quick Phrase Modifiers
|
|
#
|
|
# Quick phrase modifiers are also included, to allow formatting
|
|
# of small portions of text within a paragraph.
|
|
#
|
|
# _emphasis_
|
|
# __italicized__
|
|
# *strong*
|
|
# **bold**
|
|
# ??citation??
|
|
# -deleted text-
|
|
# +inserted text+
|
|
# ^superscript^
|
|
# ~subscript~
|
|
# @code@
|
|
# %(classname)span%
|
|
#
|
|
# ==notextile== (leave text alone)
|
|
#
|
|
# === Links
|
|
#
|
|
# To make a hypertext link, put the link text in "quotation
|
|
# marks" followed immediately by a colon and the URL of the link.
|
|
#
|
|
# Optional: text in (parentheses) following the link text,
|
|
# but before the closing quotation mark, will become a Title
|
|
# attribute for the link, visible as a tool tip when a cursor is above it.
|
|
#
|
|
# Example:
|
|
#
|
|
# "This is a link (This is a title) ":http://www.textism.com
|
|
#
|
|
# Will become:
|
|
#
|
|
# <a href="http://www.textism.com" title="This is a title">This is a link</a>
|
|
#
|
|
# === Images
|
|
#
|
|
# To insert an image, put the URL for the image inside exclamation marks.
|
|
#
|
|
# Optional: text that immediately follows the URL in (parentheses) will
|
|
# be used as the Alt text for the image. Images on the web should always
|
|
# have descriptive Alt text for the benefit of readers using non-graphical
|
|
# browsers.
|
|
#
|
|
# Optional: place a colon followed by a URL immediately after the
|
|
# closing ! to make the image into a link.
|
|
#
|
|
# Example:
|
|
#
|
|
# !http://www.textism.com/common/textist.gif(Textist)!
|
|
#
|
|
# Will become:
|
|
#
|
|
# <img src="http://www.textism.com/common/textist.gif" alt="Textist" />
|
|
#
|
|
# With a link:
|
|
#
|
|
# !/common/textist.gif(Textist)!:http://textism.com
|
|
#
|
|
# Will become:
|
|
#
|
|
# <a href="http://textism.com"><img src="/common/textist.gif" alt="Textist" /></a>
|
|
#
|
|
# === Defining Acronyms
|
|
#
|
|
# HTML allows authors to define acronyms via the tag. The definition appears as a
|
|
# tool tip when a cursor hovers over the acronym. A crucial aid to clear writing,
|
|
# this should be used at least once for each acronym in documents where they appear.
|
|
#
|
|
# To quickly define an acronym in Textile, place the full text in (parentheses)
|
|
# immediately following the acronym.
|
|
#
|
|
# Example:
|
|
#
|
|
# ACLU(American Civil Liberties Union)
|
|
#
|
|
# Will become:
|
|
#
|
|
# <acronym title="American Civil Liberties Union">ACLU</acronym>
|
|
#
|
|
# === Adding Tables
|
|
#
|
|
# In Textile, simple tables can be added by seperating each column by
|
|
# a pipe.
|
|
#
|
|
# |a|simple|table|row|
|
|
# |And|Another|table|row|
|
|
#
|
|
# Attributes are defined by style definitions in parentheses.
|
|
#
|
|
# table(border:1px solid black).
|
|
# (background:#ddd;color:red). |{}| | | |
|
|
#
|
|
# === Using RedCloth
|
|
#
|
|
# RedCloth is simply an extension of the String class, which can handle
|
|
# Textile formatting. Use it like a String and output HTML with its
|
|
# RedCloth#to_html method.
|
|
#
|
|
# doc = RedCloth.new "
|
|
#
|
|
# h2. Test document
|
|
#
|
|
# Just a simple test."
|
|
#
|
|
# puts doc.to_html
|
|
|
|
