Bug description:[PATCH] Add support for alternative try/catch syntax
Description:
------------
The attached patch adds support to alternatively open a try block using a
colon (:) in try/catch structures. When using this syntax, each catch block
must also be open by a colon, try and catch blocks must not be closed by a
closing brace (}), and the whole try/catch structure must be closed by a
"endtry" keyword.
The idea is to provide greater readability when PHP code is intermixed with
HTML code and keep consistency with constructs like if/endif, for/foreach,
etc...
Please, note that after patching, the Zend scanner and parser, as well as
ext/tokenizer_data.c should be regenerated (using re2c, bison and
tokenizer_data_gen.sh respectively, or using the provided Makefile
targets).
Test script:
---------------
<?php
try:
echo "Trying something unsafe\n";
throw new Exception('thrown using alternative try/catch syntax');
catch (int $e):
echo "Caught exception of type int (ints are not throwable, this is just
example)\n";
// several statements can also be used here
catch (Exception $e):
echo "Caught exception of type Exception: {$e->getMessage()}\n";
// several statements can also be used here
endtry;
?>
<?php try:?>
<p>Trying something unsafe</p>
<?php throw new Exception('thrown using alternative try/catch syntax');?>
<?php catch (int $e):?>
<p>Caught exception of type int (ints are not throwable, this is just
example)</p>
<?php catch (Exception $e):?>
<p>Caught exception of type Exception: <?php echo $e->getMessage();?></p>
<?php endtry;?>
Expected result:
----------------
Trying something unsafe
Caught exception of type Exception: thrown using alternative try/catch
syntax
<p>Trying something unsafe</p>
<p>Caught exception of type Exception: thrown using alternative try/catch
syntax</p>
Actual result:
--------------
PHP Parse error: syntax error, unexpected ':', expecting '{' in
/home/aaa/test.php on line 2
