From: Raphaël Gertz Date: Sun, 10 Feb 2019 05:39:19 +0000 (+0100) Subject: Remove stdbool, seems a deprecaded c99 feature X-Git-Url: https://git.rapsys.eu/bbcode/commitdiff_plain/HEAD Remove stdbool, seems a deprecaded c99 feature Add dump feature header Add pcre header Add root zend_string in bbcode_object Fix type of flag to zend_long Disable definition of not yet implemented flags Fix accordingly default flag Fix bbcode_destroy and bbcode_free prototypes to match php7 definitions Reimplement bbcode_free to correctly free ressources of custom bbcode_object Reimplement bbcode_destroy to trigger the destructor on the zend_object Fix bbcode_clone to correctly duplicate object Add comment and default members values in bbcode_create function Allow tag arg to be null (we may use that to implement a default tag array later) Implement bbcode_gen_child and bbcode_gen_parent functions (used in bbcode_check_tag) Finish implementation of bbcode_check_tag Check that tag don't contains a special chars =[]()/\\ which may trigger errors in pcre search Sanitize warning messages Add warning for empty parent array Fix immutable array detection Disable useless immutable empty array copy Add open, close and default keys generation for root and multi types Add child generation for root and multi types Add parent generation for multi and single types Add arg and img automatic support in single type Compute opattern and cpattern, that we may use later for child detection Duplicate root string to avoid any trouble with refcount Use latest style in parameters parsing in constructor Enable exception throwing to prevent the possibility to have an incomplete object returned Comment useless code in destructor Add work in progress bbcode_parse implementation Add work in progress BBCode::parse method Add various cleanup and comments --- diff --git a/bbcode.c b/bbcode.c index 5810aae..9271a96 100644 --- a/bbcode.c +++ b/bbcode.c @@ -9,7 +9,11 @@ #include "Zend/zend_exceptions.h" #include "php_bbcode.h" -#include +/* XXX: only required for php_debug_zval_dump */ +#include "ext/standard/php_var.h" + +/* XXX: required for pcre_cache_entry */ +#include "ext/pcre/php_pcre.h" /* If you declare any globals in php_bbcode.h uncomment this: ZEND_DECLARE_MODULE_GLOBALS(bbcode) @@ -18,7 +22,8 @@ ZEND_DECLARE_MODULE_GLOBALS(bbcode) typedef struct _bbcode_object { HashTable *tag; HashTable *smiley; - zval flag; + zend_string *root; + zend_long flag; zend_object std; } bbcode_object; @@ -44,7 +49,9 @@ zend_class_entry *bbcode_exception_ce; GEN(TYPE_ROOT) /*BBCODE_TYPE_ROOT*/\ GEN(TYPE_MULTI) /*BBCODE_TYPE_ARG|BBCODE_TYPE_OPTARG|BBCODE_TYPE_NOARG*/\ GEN(TYPE_SINGLE) /*BBCODE_TYPE_SINGLE*/\ - \ + +/* TODO: add again each feature when implemented (before beta) */ +#if 0 /* Quotes */ \ GEN(QUOTE_DOUBLE) /*BBCODE_ARG_DOUBLE_QUOTE*/\ GEN(QUOTE_SIMPLE) /*BBCODE_ARG_SINGLE_QUOTE*/\ @@ -65,6 +72,7 @@ zend_class_entry *bbcode_exception_ce; GEN(REMOVE_EMPTY) /*BBCODE_FLAGS_REMOVE_IF_EMPTY*/\ GEN(REMOVE_CONTENT) /*BBCODE_FLAGS_CDATA_NOT_ALLOWED*/\ GEN(REMOVE_REOPEN) /*BBCODE_FLAGS_DENY_REOPEN_CHILD*/ +#endif /* Generate enum version */ @@ -104,12 +112,18 @@ enum { }; /* Set default flag - * TODO: Set it in an ini ? */ + * TODO: Implement it in an ini file ?
