Method Detail

handleList

static void handleList(StringBuilder obj)

Takes a string object, finds list structures and changes those to XML

replaceAll

public static void replaceAll(StringBuilder builder,
                              String from,
                              String to)

handleEmph

static void handleEmph(StringBuilder obj,
                       char ch,
                       String tag)

If you want to add a _ in your text, that should be possible too... Should be done last, because no tags can appear in

Parameters:

ch - This is '_' or e.g. '*'

tag - The tag to produce, e.g. "em" or "strong"

preHandleHeaders

static void preHandleHeaders(StringBuilder obj)

Makes sure that lines indicating headers (starting with $), are followed by at least 2 newlines, if followed by some list.

Since:

MMBase-1.8.6

handleHeaders

static void handleHeaders(StringBuilder obj)

Some paragraphs are are really \sections. So this handler can be done after handleParagraphs. It will search the paragraphs which are really headers, and changes them. A header, in our 'rich' text format, is a paragraph starting with one or more $. If there are more then one, the resulting

tags are going to be nested.

handleParagraphs

static void handleParagraphs(StringBuilder obj,
                             boolean leaveExtraNewLines,
                             boolean surroundingP)

Make

tags.

Parameters:

leaveExtraNewLines - (defaults to false) if false, 2 or more newlines starts a new p. If true, every 2 newlines starts new p, and every extra new line simply stays (inside the p).

surroundingP - (defaults to true) wether the surrounding <p> should be included too.

handleParagraphs

static void handleParagraphs(StringBuilder obj,
                             boolean leaveExtraNewLines,
                             boolean surroundingP,
                             boolean placeListsInsideP)

Make <p> </p> tags. Note that if placeListsInsideP is false, the code generated with lists becomes akin to: <p>...</p><ul>...</ul><p>...</p> If placeListsInsideP is true, the code becomes: <p>...<ul>...</ul>...</p> If there is no content in front of the first list, or after the last list, those paragraphs are empty and may not be added.

Parameters:

leaveExtraNewLines - (defaults to false) if false, 2 or more newlines starts a new p. If true, every 2 newlines starts new p, and every extra new line simply stays (inside the p).

surroundingP - (defaults to true) whether the surrounding <p> should be included too.

placeListsInsideP - (defaults to false) whether a list should be placed inside a <p> (as allowed by xhtml2).

handleTables

static void handleTables(StringBuilder obj)

Wikipedia syntax for tables. (simplified)

 {|
 | a || b || c
 |-
 | d || e || f
 |}
 

or e.g.

 {|-
 |+ caption
 ! A !! B !! C
 |-
 | d
 | e
 | f
 |}
 

Since:

MMBase 1.8

cleanupText

static void cleanupText(StringBuilder obj)

Removes all new lines and space which are too much.

handleFormat

protected static void handleFormat(StringBuilder obj,
                                   boolean format)

Only escape, clean up.

Since:

MMBase-1.7

prepareDataString

protected static String prepareDataString(String data)

prepareData

protected static StringBuilder prepareData(String data)

handleRich

protected static void handleRich(StringBuilder obj,
                                 boolean sections,
                                 boolean leaveExtraNewLines,
                                 boolean surroundingP)

handleRich

protected static void handleRich(StringBuilder obj,
                                 boolean sections,
                                 boolean leaveExtraNewLines,
                                 boolean surroundingP,
                                 boolean placeListsInsideP)

handleNewlines

protected static void handleNewlines(StringBuilder obj)

richToXML

public static String richToXML(String data,
                               boolean format,
                               boolean placeListsInsideP)

Defines a kind of 'rich' text format. This is a way to easily type structured text in XML. The XML tags which can be produced by this are all HTML as well. This is a generalisation of the MMBase html() functions which does similar duties, but hopefully this one is better, and more powerfull too. The following things are recognized:

• Firstly, XMLEscape is called.
• A line starting with an asterix (*) will start an unnumberd list. The first new line not starting with a space or an other asterix will end the list
• Underscores are translated to the emphasize HTML-tag
• You can create a header tag by by starting a line with a dollar signs
• A paragraph can be begun (and ended) with an empty line.

Test with commandline: java org.mmbase.util.Encode RICH_TEXT (reads from STDIN)

Parameters:

data - text to convert

format - if the resulting XML must be nicely formatted (default: false)

Returns:

the converted text

richToXML

public static String richToXML(String data,
                               boolean format)

richToXML

public static String richToXML(String data)

poorToXML

public static String poorToXML(String data,
                               boolean format,
                               boolean placeListsInsideP)

As richToXML but a little less rich. Which means that only one new line is non significant.

poorToXML

public static String poorToXML(String data,
                               boolean format)

                                     boolean multipibleBrs,
                                     boolean surroundingP,
                                     boolean placeListsInsideP)

So poor, that it actually generates pieces of XHTML 1.1 blocks (so, no use of sections).

MMBase-1.7
