" Last Change:  2008 November 22nd
" Newsletter:   http://www.2072productions.com/?to=php-indent-for-vim-newsletter.php
" Version:	1.30
"
"
" Changes: 1.30		- Fixed empty case/default identation again :/
"			- The ResetOptions() function will be called each time
"			  the ftplugin calls this script, previously it was
"			  executed on BufWinEnter and Syntax events.
"
"
" Changes: 1.29		- Fixed php file detection for ResetOptions() used for
"			  comments formatting. It now uses the same tests as
"			  filetype.vim. ResetOptions() will be correctly
"			  called for *.phtml, *.ctp and *.inc files.
"
"
" Changes: 1.28		- End HEREDOC delimiters were not considered as such
"			  if they were not followed by a ';'.
"			- Added support for NOWDOC tags ($foo = <<<'bar')
"
"
" Changes: 1.27		- if a "case" was preceded by another "case" on the
"			  previous line, the second "case" was indented incorrectly.
"
" Changes: 1.26		- '/*' character sequences found on a line
"			  starting by a '#' were not dismissed by the indenting algorithm
"			  and could cause indentation problem in some cases.
"
"
" Changes: 1.25		- Fix some indentation errors on multi line conditions
"			  and multi line statements.
"			- Fix when array indenting is broken and a closing
"			');' is placed at the start of the line, following
"			lines will be indented correctly.
"			- New option: PHP_vintage_case_default_indent (default off)
"			- Minor fixes and optimizations.
"
"
" Changes: 1.24		- Added compatibility with the latest version of
"			  php.vim syntax file by Peter Hodge (http://www.vim.org/scripts/script.php?script_id=1571)
"			  This fixes wrong indentation and ultra-slow indenting
"			  on large php files...
"			- Fixed spelling in comments.
"
"
" Changes: 1.23		- <script> html tags are now correctly indented the same
"			  way their content is.
"			- <?.*?> (on a single line) PHP declarations are now
"			  always considered as non-PHP code and let untouched.
"
" Changes: 1.22		- PHPDoc comments are now indented according to the
"			  surrounding code.
"			- This is also true for '/* */' multi-line comments
"			  when the second line begins by a '*'.
"			- Single line '/* */' comments are also indented.
"
"
" Changes: 1.21		- 'try' and 'catch' were not registered as block starters so the '{'
"			  after a 'try' or 'catch' could be wrongly indented...
"			  (thanks to Gert Muller for finding this issue)
"
" Changes: 1.20		- Line beginning by a single or double quote followed
"			  by a space would cause problems... this was related
"			  to the bug correction of version 1.10 - Thanks to
"			  David Fishburn for finding this (he was lucky).
"			- Changed the way this script set the 'formatoptions'
"			  setting, now it uses '-=' and '+='
"			- New option: PHP_autoformatcomment (defaults to 1),
"			  if set to 0 the 'formatoptions' setting will not be
"			  altered.
"			- When PHP_autoformatcomment is not 0, the 'comments'
"			  setting is set to the type of comments that PHP
"			  supports.
"
" Changes: 1.19		- Indentation of '*/' delimiter of '/**/' won't be broken by
"			  strings or '//' comments containing the "/*" character sequence.
"
" Changes: 1.182	- I Forgot to register 'interface' and 'abstract' as block starters so the '{'
"			  after them could be wrongly indented...
"
" Changes: 1.181	- I Forgot to register 'class' as a block starter so the '{'
"			  after a 'class' could be wrongly indented...
"
" Changes: 1.18		- No more problems with Vim 6.3 and UTF-8.
"			- Opening braces "{" are always indented according to their block starter.
"
"				Instead of:
"
"					if( $test
"					    && $test2 )
"					    {
"					    }
"
"				You have:
"
"					if( $test
"					    && $test2 )
"					{
"					}
"
"
" Changes: 1.17		- Now following parts of split lines are indented:
"
"				Instead of:
"
"					$foo=
"					"foo"
"					."foo";
"
"				You have:
"
"					$foo=
"					    "foo"
"					    ."foo";
"
"			- If a "case : break;" was declared on a single line, the
"			  following "case" was not indented correctly.
"			- If a </script> html tag was preceded by a "?>" it wasn't indented.
"			- Some other minor corrections and improvements.
"
"
" Changes: 1.16		- Now starting and ending '*' of multiline '/* */' comments are aligned
"			  on the '*' of the '/*' comment starter.
"			- Some code improvements that make indentation faster.
"
" Changes: 1.15		- Corrected some problems with the indentation of
"			  multiline "array()" declarations.
"
" Changes: 1.14		- Added auto-formatting for comments (using the Vim option formatoptions=qroc).
"			- Added the script option PHP_BracesAtCodeLevel to
"			  indent the '{' and '}' at the same level than the
"			  code they contain.
"
" Changes: 1.13		- Some code cleaning and typo corrections (Thanks to
"			  Emanuele Giaquinta for his patches)
"
" Changes: 1.12		- The bug involving searchpair() and utf-8 encoding in Vim 6.3 will
"			  not make this script to hang but you'll have to be
"			  careful to not write '/* */' comments with other '/*'
"			  inside the comments else the indentation won't be correct.
"			  NOTE: This is true only if you are using utf-8 and vim 6.3.
"
" Changes: 1.11		- If the "case" of a "switch" wasn't alone on its line
"			  and if the "switch" was at col 0 (or at default indenting)
"			  the lines following the "case" were not indented.
"
" Changes: 1.10		- Lines beginning by a single or double quote were
"			  not indented in some cases.
"
" Changes: 1.09		- JavaScript code was not always directly indented.
"
" Changes: 1.08		- End comment tags '*/' are indented like start tags '/*'.
"			- When typing a multiline comment, '}' are indented
"			  according to other commented '{'.
"			- Added a new option 'PHP_removeCRwhenUnix' to
"			  automatically remove CR at end of lines when the file
"			  format is Unix.
"			- Changed the file format of this very file to Unix.
"			- This version seems to correct several issues some people
"			  had with 1.07.
"
" Changes: 1.07		- Added support for "Here document" tags:
"			   - HereDoc end tags are indented properly.
"			   - HereDoc content remains unchanged.
"			- All the code that is outside PHP delimiters remains
"			  unchanged.
"			- New feature: The content of <script.*> html tags is considered as PHP
"			  and indented according to the surrounding PHP code.
"			- "else if" are detected as "elseif".
"			- Multiline /**/ are indented when the user types it but
"			  remain unchanged when indenting from their beginning.
"			- Fixed indenting of // and # comments.
"			- php_sync_method option is set to 0 (fromstart).
"			  This is required for complex PHP scripts else the indent
"			  may fail.
"			- Files with non PHP code at the beginning could alter the indent
"			  of the following PHP code.
"			- Other minor improvements and corrections.
"
" Changes: 1.06:    - Switch block were no longer indented correctly...
"		    - Added an option to use a default indenting instead of 0.
"		      (whereas I still can't find any good reason to use it!)
"		    - A problem with ^\s*);\= lines where ending a non '{}'
"		      structure.
"		    - Changed script local variable to be buffer local
"		      variable instead.
"
" Changes: 1.05:    - Lines containing "<?php ?>" and "?> <?php"
"		      (start and end tag on the same line) are no
"		      longer indented at col 1 but as normal code.
"
" Changes: 1.04:    - Strings containing "//" could break the indenting
"		      algorithm.
"		    - When a '{}' block was at col 1, the second line of the
"		      block was not indented at all (because of a stupid
"		      optimization coupled with a bug).
"
" Changes: 1.03:    - Some indenting problems corrected: end of non '{}'
"		      structures was not detected in some cases. The part of
"		      code concerned have been re-written
"		    - PHP start tags were not indented at col 1
"		    - Wrong comment in the code have been corrected
"
" Changes: 1.02:    - The bug I was talking about in version 1.01 (right below) has
"		      been corrected :)
"		    - Also corrected another bug that could occur in
"		      some special cases.
"		    - I removed the debug mode left in 1.01 that could
"		      cause some Vim messages at loading if other script were
"		      bugged.
"
" Changes: 1.01:    - Some little bug corrections regarding automatic optimized
"		      mode that missed some tests and could break the indenting.
"		    - There is also a problem with complex non bracketed structures, when several
"		      else are following each other, the algorithm do not indent the way it
"		      should.
"		      That will be corrected in the next version.
"
"  If you find a bug, please e-mail me at John.wellesz (AT) teaser (DOT) fr
"  with an example of code that breaks the algorithm.
"
"
"	Thanks a lot for using this script.
"

" NOTE: This script must be used with PHP syntax ON and with the php syntax
"	script by Lutz Eymers (http://www.isp.de/data/php.vim ) or with the
"	script by Peter Hodge (http://www.vim.org/scripts/script.php?script_id=1571 )
"	the later is bunbdled by default with Vim 7.
"
"
"	In the case you have syntax errors in your script such as HereDoc end
"	identifiers not at col 1 you'll have to indent your file 2 times (This
"	script will automatically put HereDoc end identifiers at col 1 if
"	they are followed by a ';').
"

" NOTE: If you are editing file in Unix file format and that (by accident)
" there are '\r' before new lines, this script won't be able to proceed
" correctly and will make many mistakes because it won't be able to match
" '\s*$' correctly.
" So you have to remove those useless characters first with a command like:
"
" :%s /\r$//g
"
" or simply 'let' the option PHP_removeCRwhenUnix to 1 and the script will
" silently remove them when VIM load this script (at each bufread).


" Options: PHP_autoformatcomment = 0 to not enable autoformating of comment by
"		    default, if set to 0, this script will let the 'formatoptions' setting intact.
"
" Options: PHP_default_indenting = # of sw (default is 0), # of sw will be
"		   added to the indent of each line of PHP code.
"
" Options: PHP_removeCRwhenUnix = 1 to make the script automatically remove CR
"		   at end of lines (by default this option is unset), NOTE that you
"		   MUST remove CR when the fileformat is UNIX else the indentation
"		   won't be correct!
"
" Options: PHP_BracesAtCodeLevel = 1 to indent the '{' and '}' at the same
"		   level than the code they contain.
"		   Exemple:
"			Instead of:
"				if ($foo)
"				{
"					foo();
"				}
"
"			You will write:
"				if ($foo)
"					{
"					foo();
"					}
"
"			NOTE: The script will be a bit slower if you use this option because
"			some optimizations won't be available.
"
" Options: PHP_vintage_case_default_indent = 1 (defaults to 0) to add a meaningless indent
"		    befaore 'case:' and 'default":' statement in switch blocks.

" Remove all the comments from this file:
" :%s /^\s*".*\({{{\|xxx\)\@<!\n\c//g
" }}}

" They also prevent the load of different indent scripts for PHP at the same time.
