    Most unusual characters can be directly entered without any problems.

    If you do encounter problems, try using HTML character entities. A common example looks like &amp; for an ampersand & character. For a full list of entities see HTML's entities page. Some of the available characters include:

    Character Description You Type You Get
    Ampersand &amp; &
    Greater than &gt; >
    Less than &lt; <
    Quotation mark &quot; "
  • Syntax highlighting of source code can be enabled with the following tags:

      Generic syntax highlighting tags: <code>, <blockcode>.
    • Language specific syntax highlighting tags: <cpp> for C++ source code, <java> for Java source code, <php> for PHP source code

    Options and tips:

    • The language for the generic syntax highlighting tags can be specified with one of the attribute(s): type, lang, language, class. The possible values are: "bash" (for Bash), "c" (for C), "cpp" (for C++), "csharp" (for C#), "css" (for CSS), "ecmascript" (for ECMAScript), "go" (for Go), "html4strict" (for HTML), "html5" (for HTML5), "java" (for Java), "javascript" (for Javascript), "jquery" (for jQuery), "mysql" (for MySQL), "objc" (for Objective-C), "perl" (for Perl), "perl6" (for Perl 6), "php" (for PHP), "postgresql" (for PostgreSQL), "powershell" (for PowerShell), "python" (for Python), "rails" (for Rails), "rpmspec" (for RPM Specification File), "sql" (for SQL), "swift" (for Swift), "tsql" (for T-SQL), "xml" (for XML), "yaml" (for YAML).
    • The supported tag styles are: <foo>, [foo].
    • Line numbering can be enabled/disabled with the attribute "linenumbers". Possible values are: "off" for no line numbers, "normal" for normal line numbers and "fancy" for fancy line numbers (every nth line number highlighted). The start line number can be specified with the attribute "start", which implicitly enables normal line numbering. For fancy line numbering the interval for the highlighted line numbers can be specified with the attribute "fancy", which implicitly enables fancy line numbering.
    • If the source code between the tags contains a newline (e.g. immediatly after the opening tag), the highlighted source code will be displayed as a code block. Otherwise it will be displayed inline.
    • A title can be added to a code block with the attribute "title".

    Defaults:

    • Default highlighting mode for generic syntax highlighting tags: when no language attribute is specified, no syntax highlighting will be done.
    • Default line numbering: no line numbers.
  • Web page addresses and email addresses turn into links automatically.
  • Lines and paragraphs are automatically recognized. The <br /> line break, <p> paragraph and </p> close paragraph tags are inserted automatically. If paragraphs are not recognized simply add a couple of blank lines.
