=head1 SYNOPSIS |
| |
|
| |
This file contains a table driven entity-->latex converter. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |
| |
|
| |
=head1 OVERVIEW |
| |
|
| |
|
| |
Assumptions: |
| |
The number of entities in a resource is small compared with the |
| |
number of possible entities that might be translated. |
| |
Therefore the strategy is to match a general entity pattern |
| |
&.+; over and over, pull out the match look it up in an entity -> tex hash |
| |
and do the replacement. |
| |
|
| |
In order to simplify the hash, the following reductions are done: |
| |
&#d+; have the &# and ; stripped and is converted to an int. |
| |
&#.+; have the &#x and ; stripped and is converted to an int as a hex |
| |
value. |
| |
All others have the & and ; stripped. |
| |
|
| |
|
| |
The hash: Add new conversions here; leave off the leading & and the trailing ; |
| |
all numeric entities need only appear as their decimal versions |
| |
(e.g. no need for 1234 is sufficient, no need for 0x4d2 as well. |
| |
|
| |
This entity table is mercilessly cribbed from the HTML pocket reference |
| |
table starting at pg 82. In most cases the LaTeX equivalent codes come from |
| |
the original massive regular expression replacements originally by |
| |
A. Sakharuk in lonprintout.pm |
| |
|
| |
I also want to acknowledge |
| |
ISO Character entities and their LaTeX equivalents by |
| |
Vidar Bronken Gundersen, and Rune Mathisen |
| |
http://www.bitjungle.com/isoent-ref.pdf |
| |
|
| |
|
| |
Note numerical entities are essentially unicode character codes. |
| |
|
| |

=head1 SUBROUTINES |

|
| |
=item entity_to_utf8() |
| |
|
| |
|
| |
Convert a numerical entity (that does not exist in our hash) |
| |
to its UTF-8 equivalent representation. |
| |
This allows us to support, to some extent, any entity for which |
| |
dvipdf can find a gylph (given that LaTeX is now UTF-8 clean). |
| |
|
| |
Parameters: |
| |
unicode - The unicode for the character. This is assumed to |
| |
be a decimal value |
| |
Returns: |
| |
The UTF-8 equiavalent of the value. |
| |
|
| |
=item entity_to_latex() |
| |
|
| |
Convert an entity to the corresponding LateX if possible. |
| |
If not possible, and the entity is numeric, |
| |
the entity is treated like a Unicode character and converted |
| |
to UTF-8 which should display as long as dvipdf can find the |
| |
appropriate glyph. |
| |
|
| |
The entity is assumed to have already had the |
| |
&; or & ; removed |
| |
|
| |
Parameters: |
| |
entity - Name of entity to convert. |
| |
Returns: |
| |
One of the following: |
| |
- Latex string that produces the entity. |
| |
- UTF-8 equivalent of a numeric entity for which we don't have a latex string. |
| |
- ' ' for text entities for which there's no latex equivalent. |
| |
|
| |
|
| |
=item replace_entities() |
| |
|
| |
Convert all the entities in a string. |
| |
We locate all the entities, pass them into entity_to_latex and |
| |
and replace occurences in the input string. |
| |
The assumption is that there are few entities in any string/document |
| |
so this looping is not too bad. The advantage of looping vs. regexping is |
| |
that we now can use lookup tables for the translation in entity_to_latex above. |
| |
|
| |
Parameters: |
| |
input - Input string/document |
| |
Returns |
| |
input with entities replaced by latexable stuff (UTF-8 encodings or |
| |
latex control strings to produce the entity. |
