Copyright (C) 2000 Norman Walsh.

- * - *

This class provides the guts of a - * Saxon 6.* - * implementation of callouts for verbatim environments. (It is used - * by the Verbatim class.)

- * - *

The general design is this: the stylesheets construct a result tree - * fragment for some verbatim environment. The Verbatim class initializes - * a CalloutEmitter with information about the callouts that should be applied - * to the verbatim environment in question. Then the result tree fragment - * is "replayed" through the CalloutEmitter; the CalloutEmitter builds a - * new result tree fragment from this event stream, decorated with callouts, - * and that is returned.

Copyright (C) 2000 Norman Walsh.

- * - *

This class provides a - * Saxon - * implementation of some code to adjust CALS Tables to HTML - * Tables.

- * - *

Column Widths

- *

The adjustColumnWidths method takes a result tree - * fragment (assumed to contain the colgroup of an HTML Table) - * and returns the result tree fragment with the column widths - * adjusted to HTML terms.

- * - *

Convert Lengths

- *

The convertLength method takes a length specification - * of the form 9999.99xx (where "xx" is a unit) and returns that length - * as an integral number of pixels. For convenience, percentage lengths - * are returned unchanged.

- *

The recognized units are: inches (in), centimeters (cm), - * millimeters (mm), picas (pc, 1pc=12pt), points (pt), and pixels (px). - * A number with no units is assumed to be pixels.

Adjust column widths in an HTML table.

- * - *

The specification of column widths in CALS (a relative width - * plus an optional absolute width) are incompatible with HTML column - * widths. This method adjusts CALS column width specifiers in an - * attempt to produce equivalent HTML specifiers.

- * - *

In order for this method to work, the CALS width specifications - * should be placed in the "width" attribute of the <col>s within - * a <colgroup>. Then the colgroup result tree fragment is passed - * to this method.

- * - *

This method makes use of two parameters from the XSL stylesheet - * that calls it: nominal.table.width and - * table.width. The value of nominal.table.width - * must be an absolute distance. The value of table.width - * can be either absolute or relative.

- * - *

Presented with a mixture of relative and - * absolute lengths, the table width is used to calculate - * appropriate values. If the table.width is relative, - * the nominal width is used for this calculation.

- * - *

There are three possible combinations of values:

- * - *
    - *
  1. There are no relative widths; in this case the absolute widths - * are used in the HTML table.
    2. - *
  2. There are no absolute widths; in this case the relative widths - * are used in the HTML table.
    3. - *
  3. There are a mixture of absolute and relative widths: - *
      - *
    1. If the table width is absolute, all widths become absolute.
      2. - *
    2. If the table width is relative, make all the widths absolute - * relative to the nominal table width then turn them all - * back into relative widths.

Copyright (C) 2000 Norman Walsh.

- * - *

This class provides a - * Saxon - * implementation of two features that would be impractical to - * implement directly in XSLT: line numbering and callouts.

- * - *

Line Numbering

- *

The numberLines method takes a result tree - * fragment (assumed to contain the contents of a formatted verbatim - * element in DocBook: programlisting, screen, address, literallayout, - * or synopsis) and returns a result tree fragment decorated with - * line numbers.

- * - *

Callouts

- *

The insertCallouts method takes an - * areaspec and a result tree fragment - * (assumed to contain the contents of a formatted verbatim - * element in DocBook: programlisting, screen, address, literallayout, - * or synopsis) and returns a result tree fragment decorated with - * callouts.

Number lines in a verbatim environment

- * - *

The extension function expects the following variables to be - * available in the calling context: $linenumbering.everyNth, - * $linenumbering.width, $linenumbering.separator, and - * $stylesheet.result.type.

- * - *

This method adds line numbers to a result tree fragment. Each - * newline that occurs in a text node is assumed to start a new line. - * The first line is always numbered, every subsequent 'everyNth' line - * is numbered (so if everyNth=5, lines 1, 5, 10, 15, etc. will be - * numbered. If there are fewer than everyNth lines in the environment, - * every line is numbered.

- * - *

Every line number will be right justified in a string 'width' - * characters long. If the line number of the last line in the - * environment is too long to fit in the specified width, the width - * is automatically increased to the smallest value that can hold the - * number of the last line. (In other words, if you specify the value 2 - * and attempt to enumerate the lines of an environment that is 100 lines - * long, the value 3 will automatically be used for every line in the - * environment.)

- * - *

The 'separator' string is inserted between the line - * number and the original program listing. Lines that aren't numbered - * are preceded by a 'width' blank string and the separator.

- * - *

If inline markup extends across line breaks, markup changes are - * required. All the open elements are closed before the line break and - * "reopened" afterwards. The reopened elements will have the same - * attributes as the originals, except that 'name' and 'id' attributes - * are not duplicated if the stylesheet.result.type is "html" and - * 'id' attributes will not be duplicated if the result type is "fo".

- * - * @param context The current stylesheet context. - * @param rtf_ns The result tree fragment of the verbatim environment. - * - * @return The modified result tree fragment. - */ - public static NodeSetValue numberLines (Context context, - NodeSetValue rtf_ns) { - - FragmentValue rtf = (FragmentValue) rtf_ns; - - setupLineNumbering(context); - - try { - LineCountEmitter lcEmitter = new LineCountEmitter(); - rtf.replay(lcEmitter); - int numLines = lcEmitter.lineCount(); - - int listingModulus = numLines < modulus ? 1 : modulus; - - double log10numLines = Math.log(numLines) / Math.log(10); - - int listingWidth = width < log10numLines+1 - ?

Insert text callouts into a verbatim environment.

- * - *

This method examines the areaset and area elements - * in the supplied areaspec and decorates the supplied - * result tree fragment with appropriate callout markers.

- * - *

If a label attribute is supplied on an area, - * its content will be used for the label, otherwise the callout - * number will be used, surrounded by parenthesis. Callout numbers may - * also be represented as graphics. Callouts are - * numbered in document order. All of the areas in an - * areaset get the same number.

- * - *

Only the linecolumn and linerange units are - * supported. If no unit is specifed, linecolumn is assumed. - * If only a line is specified, the callout decoration appears in - * the defaultColumn. Lines will be padded with blanks to reach the - * necessary column, but callouts that are located beyond the last - * line of the verbatim environment will be ignored.

- * - *

Callouts are inserted before the character at the line/column - * where they are to occur.

- * - *

If graphical callouts are used, and the callout number is less - * than or equal to the $callout.graphics.number.limit, the following image - * will be generated for HTML: - * - * 

-   * <img src="$callout.graphics.path/999$callout.graphics.ext"
-   *         alt="conumber">
-   *

-   * <fo:external-graphic src="$callout.graphics.path/999$callout.graphics.ext"/>

- * - *

This class provides a - * Xalan - * implementation of some code to adjust CALS Tables to HTML - * Tables.

- * - *

Column Widths

- *

The adjustColumnWidths method takes a result tree - * fragment (assumed to contain the colgroup of an HTML Table) - * and returns the result tree fragment with the column widths - * adjusted to HTML terms.

- * - *

Convert Lengths

- *

The convertLength method takes a length specification - * of the form 9999.99xx (where "xx" is a unit) and returns that length - * as an integral number of pixels. For convenience, percentage lengths - * are returned unchanged.

- *

The recognized units are: inches (in), centimeters (cm), - * millimeters (mm), picas (pc, 1pc=12pt), points (pt), and pixels (px). - * A number with no units is assumed to be pixels.

Adjust column widths in an HTML table.

- * - *

The specification of column widths in CALS (a relative width - * plus an optional absolute width) are incompatible with HTML column - * widths. This method adjusts CALS column width specifiers in an - * attempt to produce equivalent HTML specifiers.

- * - *

In order for this method to work, the CALS width specifications - * should be placed in the "width" attribute of the <col>s within - * a <colgroup>. Then the colgroup result tree fragment is passed - * to this method.

- * - *

This method makes use of two parameters from the XSL stylesheet - * that calls it: nominal.table.width and - * table.width. The value of nominal.table.width - * must be an absolute distance. The value of table.width - * can be either absolute or relative.

- * - *

Presented with a mixture of relative and - * absolute lengths, the table width is used to calculate - * appropriate values. If the table.width is relative, - * the nominal width is used for this calculation.

- * - *

There are three possible combinations of values:

- * - *
    - *
  1. There are no relative widths; in this case the absolute widths - * are used in the HTML table.
    2. - *
  2. There are no absolute widths; in this case the relative widths - * are used in the HTML table.
    3. - *
  3. There are a mixture of absolute and relative widths: - *
      - *
    1. If the table width is absolute, all widths become absolute.
      2. - *
    2. If the table width is relative, make all the widths absolute - * relative to the nominal table width then turn them all - * back into relative widths.

Copyright (C) 2001 Norman Walsh.

- * - *

This class provides a - * Xalan - * implementation of two features that would be impractical to - * implement directly in XSLT: line numbering and callouts.

- * - *

Line Numbering

- *

The numberLines family of functions takes a result tree - * fragment (assumed to contain the contents of a formatted verbatim - * element in DocBook: programlisting, screen, address, literallayout, - * or synopsis) and returns a result tree fragment decorated with - * line numbers.

- * - *

Callouts

- *

The insertCallouts family of functions takes an - * areaspec and a result tree fragment - * (assumed to contain the contents of a formatted verbatim - * element in DocBook: programlisting, screen, address, literallayout, - * or synopsis) and returns a result tree fragment decorated with - * callouts.

Number lines in a verbatim environment.

- * - *

This method adds line numbers to a result tree fragment. Each - * newline that occurs in a text node is assumed to start a new line. - * The first line is always numbered, every subsequent xalanMod line - * is numbered (so if xalanMod=5, lines 1, 5, 10, 15, etc. will be - * numbered. If there are fewer than xalanMod lines in the environment, - * every line is numbered.

- * - *

xalanMod is taken from the $linenumbering.everyNth parameter.

- * - *

Every line number will be right justified in a string xalanWidth - * characters long. If the line number of the last line in the - * environment is too long to fit in the specified width, the width - * is automatically increased to the smallest value that can hold the - * number of the last line. (In other words, if you specify the value 2 - * and attempt to enumerate the lines of an environment that is 100 lines - * long, the value 3 will automatically be used for every line in the - * environment.)

- * - *

xalanWidth is taken from the $linenumbering.width parameter.

- * - *

The xalanSep string is inserted between the line - * number and the original program listing. Lines that aren't numbered - * are preceded by a xalanWidth blank string and the separator.

- * - *

xalanSep is taken from the $linenumbering.separator parameter.

- * - *

If inline markup extends across line breaks, markup changes are - * required. All the open elements are closed before the line break and - * "reopened" afterwards. The reopened elements will have the same - * attributes as the originals, except that 'name' and 'id' attributes - * are not duplicated.
