Change log for Text::Templet

For the most recent updates and source code for all versions, see http://www.denispetrov.com/magic/

3.0

• Complete rework: reduced the amount of code by 75% TO ~50 lines
• Improved performance by 500-1000%, depending on template
• HeaderCallback deprecated and removed

2.9

• Bugfix: package context now honored in recursive calls to Templet()

2.8

• Added Use() function and HeaderCallback callback
• Bugfix: multiple warnings now correctly propagated
• Processing stops and die() is called if a code section contains errors

2.5

• Added asterisk labels functionality - see documentation
• Changed license from GPL to Perl Artistic License
• Minor performance improvements

2.4

• Updated documentation and change log.
• In case of an error in a code section of the template, returns empty string instead of '1' 2.3
• In non-void context, Templet will return the processed template instead of printing it to the default output

2.1

• Updated POD text in the module

2.0

• Prepared Magic for inclusion to CPAN
• Magic is now an independent project, hence major version number update
• Bugfix: renamed internal Magic variables to reduce the chance of them clashing with variables used in a template

1.16

• I made Magic() re-entry safe, which allows parts of the target text to be generated by a separate Magic() call enclosed in a subroutine called from another Magic template. That subroutine could then be shared among different templates, enabling "include"-type functionality. It could be considered a feature, but it really is a bugfix as I could've easily made it re-entrant from the beginning, but was too lazy :)

1.14

• I converted Magic to a Perl module as I figured out how to switch to the namespace of the package Magic was called from so the package variables could be accessed without having to qualify them (i.e. $magic vs. $Package::magic). This works much better with mod_perl as now you no longer have to put all your pages into package main in order to use unqualified names and having to invent unique names for functions throughout the entire site! Additionally, now you can tuck it away into your libraries and reuse it for multiple applications.

1.13

• Implemented proper handling of warnings thrown from template sections and writing them nicely formatted into the error log. Now Magic tells you on which line of the template the problematic section begins. It gives you the line number in the template text and also the line number of your perl file, if you embedded the template into your code using "quote here" construct.

1.12

• Fixed a bug introduced by the change in 1.11 which caused template processing to stop when a code section returned undef, not just when an error occured.

1.11

• It turned out that in many situations an error in code section would lead to an infinite loop. Now Magic will stop when processing of a code section produces an error.

1.10

• Bugfix - Magic would post a warning if a code or text section returned undef regardless of whether it was caused by an error or not.

1.9

• Fixed a bug that caused duplicate labels in skipped sections of template not being reported. For example, neither of the following fragments would trigger a warning about a duplicate label 'DUP': <% "SKIP_DUP" if 1 %><%DUP%><%DUP%><%SKIP_DUP%> or <% "SKIP_DUP" if 1 %><%DUP%><%SKIP_DUP%><%DUP%>

1.8

• Changed label name syntax - now it must begin with a letter or an underscore. This resolved an issue of warnings being issued about non-existent label '1' when a code section returned a boolean value. For example, the following useful code would produce this warning: <% 'SKIP_HERE' unless $do_not_skip %> when $do_not_skip contained 1.

1.7

• Fixed a bug in diagnostics code that caused incorrect duplicate label warnings issued.

1.6

• New functionality - implicit labels appended to the template, "_" at the beginning and "END" at the end. This fixes the issue of the template text prior to the first <% %> section being ignored.
• Added a diagnostic message warning about duplicate labels.
• Added a diagnostic message warning about a code section returning a nonexistent label.
• Now code sections can span multiple lines.
• Fixed a bug - the code was calling $Q->print() for output assuming that $Q was a reference to an instance of CGI object. Changed that to a simple print() call.

1.4

• Added diagnostic logging. Magic will call warn() with an error message and will include the section of the template that caused the error.
• Fixed a bug that caused Magic to post a message to the error log every time a code section returned undef.

1.3

• Initial revision
