" " 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 files 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). if exists("b:did_indent") finish endif let b:did_indent = 1 let php_sync_method = 0 if exists("PHP_default_indenting") let b:PHP_default_indenting = PHP_default_indenting * &sw else let b:PHP_default_indenting = 0 endif if exists("PHP_outdentSLComments") let b:PHP_outdentSLComments = PHP_outdentSLComments * &sw else let b:PHP_outdentSLComments = 0 endif if exists("PHP_BracesAtCodeLevel") let b:PHP_BracesAtCodeLevel = PHP_BracesAtCodeLevel else let b:PHP_BracesAtCodeLevel = 0 endif if exists("PHP_autoformatcomment") let b:PHP_autoformatcomment = PHP_autoformatcomment else let b:PHP_autoformatcomment = 1 endif if exists("PHP_outdentphpescape") let b:PHP_outdentphpescape = PHP_outdentphpescape else let b:PHP_outdentphpescape = 1 endif if exists("PHP_vintage_case_default_indent") && PHP_vintage_case_default_indent let b:PHP_vintage_case_default_indent = 1 else let b:PHP_vintage_case_default_indent = 0 endif let b:PHP_lastindented = 0 let b:PHP_indentbeforelast = 0 let b:PHP_indentinghuge = 0 let b:PHP_CurrentIndentLevel = b:PHP_default_indenting let b:PHP_LastIndentedWasComment = 0 let b:PHP_InsideMultilineComment = 0 let b:InPHPcode = 0 let b:InPHPcode_checked = 0 let b:InPHPcode_and_script = 0 let b:InPHPcode_tofind = "" let b:PHP_oldchangetick = b:changedtick let b:UserIsTypingComment = 0 let b:optionsset = 0 setlocal nosmartindent setlocal noautoindent setlocal nocindent setlocal nolisp setlocal indentexpr=GetPhpIndent() setlocal indentkeys=0{,0},0),:,!^F,o,O,e,*,=?>,=\|\%(}\s*\)\?else\>\|do\>\|while\>\|switch\>\|case\>\|default\>\|for\%(each\)\=\>\|declare\>\|class\>\|trait\>\|use\>\|interface\>\|abstract\>\|final\>\|try\>\|\%(}\s*\)\=catch\>\|\%(}\s*\)\=finally\>\)' let s:functionDecl = '\\%(\s\+[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*\)\=\s*(.*' let s:endline= '\s*\%(//.*\|#.*\|/\*.*\*/\s*\)\=$' let s:terminated = '\%(\%(;\%(\s*\%(?>\|}\)\)\=\|<<<''\=\a\w*''\=$\|^\s*}\)'.s:endline.'\)\|^[^''"`]*[''"`]$' let s:PHP_startindenttag = '\)\@!\|]*>\%(.*<\/script>\)\@!' let s:escapeDebugStops = 0 function!
