After commit b66d2bec67 'document: Unify text style -> screen attribute handling', the case statements for CSS_PT_FONT_WEIGHT, CSS_PT_FONT_STYLE, and CSS_PT_TEXT_DECORATION all have common code and therefore collapse nicely.
Pass the session with some get_opt_* calls. These are the low-hanging fruit. Some places will be difficult because we don't have the session or for other reasons.
Note that this is the infrastructure, but all relevant get_opt_* calls must be changed to pass the session so that the domain-specific options are looked up.
Add @want_domain parameter to parse_set_common and read in the domain-name if the flag is set.
Add parse_set_domain wrapper for parse_set_common.
Add "set_domain" configuration directive with the following syntax: set_domain domain option = value
Modify create_config_string and smart_config_output_fn to spit out domain-specific option trees.
Add @smart_config_output_fn_domain global variable to facilitate this.
Define structure domain_tree and define list @domain_trees.
Add routine get_domain_tree to find or, if necessary, create the shadow tree for the given domain name.
Add routine get_domain_option search for an option in all domain shadow-trees and return the option in the best matching domain tree.
Modify get_opt_ to use get_domain_option to check for domain-specific options.
Add clean-up routine done_domain_trees, called on exit, to free any domain trees.
change_hook_active_link: pass update_cache_document_options @ses.
Now when changing the global settings, it will not simply copy the new values for the global settings to the document-options cache, but also check session-specific settings. This doesn't really matter yet, since the options in question can't be set on a per-session basis, but is in preparation for future changes.
Before, *_html_parser_state() operated with struct html_element *. Now, it is
transparent for the renderer (just void *), so that DOM won't have to provide
this struct but will be able to use something internal.
Normally, you can add some objects or subdirs to the build if some
config variable is set to yes, by doing:
SUBDIRS-$(CONFIG_FOO)
Now you can do it the other way too, including stuff if some
variable is set to no:
SUBDIRS-unless$(CONFIG_FOO)
This will be used for switching between two HTML parser implementations.
...as struct text_style. This way it might be possible later to
add other default formatting attributes by CSS and it allows
quite a code simplification in the DOM renderer.
Currently, all DOM, HTML and plain renderers had their own routine for
conversion from text style to screen attribute. This moves text_style and
text_style_format from html/parser.h to renderer.h and introduces new generic
routine get_screen_chracter_template() that is used by all the specific
rendering engines.
The parsing in parse_set and parse_unset saves, overwrites with a NUL, and restores a character in the string that is being parsed. If there is a malloc failure between overwriting and restoring, the restore is not done. This commit changes that behaviour to restore before returning.
Now, CSS is initialized separately for each of the renderers, so that
also RSS doesn't just choose styles of random DOM node types.
init_template_by_style() is introduced as the common backend for
loading CSS properties.
Introduce get_option_shadow. This routine takes an option, the tree under which that option resides, and another tree. It returns a corresponding option with parallel ancestry in the second tree, creating that option and ancestry if it does not already exist.
Add enum copy_option_flags.
Add the CO_NO_LISTBOX_ITEM flag, which is used to suppress listbox creation for shadowed trees.
Add the CO_SHALLOW flag, which is used to suppress the duplication of unwanted children for shadowed trees.
Add a flags parameter to copy_option and tree_dup (and out of necessity, struct option_type_info and str_dup).
