Added a script to selectively compile theme CSS. In order to allow
compiling on per theme basis without purging all theme CSS in the
local cache I have made some changes to how CSS is compiled and
how it is accessed via local cache.
The previous behaviour was to only lock when in theme designer mode.
As a result, when generating the theme for after a reset, each new
client was starting the generation afresh and no locking was taking
place at all.
This only applied when themedesignermode was disabled, because the
first chunk is 0, but 0 is resolved to false. We needed to compare
$chunk with null in order to know if it was set.
Theme images, css and JS are broken by PHP error messages which creates major problems for production sites with enabled displaying of errors because the files are cached indefinitely. It is better to send the errors and notices to logs only, in any case all developers must learn to use error logs.
* Writing lots more PHPdoc comments for all the settings.
* Strip the comments from the standard theme config.php (see below)
* Move finding the layout template from moodle_core_renderer to the theme_config class
* Move loading meta.php files from moodle_core_renderer to the theme_config class
* MDL-19719 Remove support for $THEME->langsheets, and lang/.../styles.php
* MDL-19719 Put the Vietnamese-specific code into the standard theme
* Support for styles.php in all plugin types (at the theme's discretion). (c/f MDL-16438)
* More PHP doc comments for moodle_core_renderer methods.
About stripping comments from config.php: I'm not sure if this
is a good idea, and I may revert this bit. I am hoping that once
http://phpdocs.moodle.org/HEAD/moodlecore/theme_config.html has
been updated, that will be better than copying and pasting these
comments into every theme. I intend to post in the themes forum
to canvas opinions.
This is part of http://docs.moodle.org/en/Development:Theme_engines_for_Moodle%3F
$THEME is now initialised at the same time as $OUTPUT. Old functions like
theme_setup are deprecated in favour of methods on $PAGE. There is a new
theme_config class in outputlib.php that deals with loading the theme config.php file.
CSS used to be served by themes styles.php files calling a function in weblib.php.
Now it works by each theme's styles.php file doing
$themename = basename(dirname(__FILE__));
require_once(dirname(__FILE__) . '/../../theme/styles.php');
which is less code to be copied into each theme. (Old-style styles.php files still
work thanks to some code in deprecatedlib.php.)
Admin UI for choosing a theme cleaned up.
A couple of theme-specific hard-coded hacks like $THEME->cssconstants and
$THEME->CSSEdit have been replaced by a more generic $THEME->customcssoutputfunction
hook. See examples at the end of outputlib.php
Also:
* Fix setting the theme in the URL, which seems to have been broken since 1.9.
* Fix up errors on a few pages caused by the new initialisation order.
* MDL-19097 moodle_page::set_course should not set $COURSE unless it is $PAGE.
* httpsrequired() from moodlelib.php moved to $PAGE->https_required().
* Move has_started() method to the renderer base class.
* Further fixes to display of early errors.
* Remove print_header/footer_old from weblib. I did not mean to commit them before.
