1 This files describes API changes in /theme/* themes,
2 information provided here is intended especially for theme designer.
6 * A new theme config 'undeletableblocktypes' allows a theme to define which blocks are deletable.
7 * A new core setting now enables admins to upload the logos of their site. Using the
8 following methods, themers can instantly support branding logos without the need
9 to implement specific theme settings:
10 * $OUTPUT->get_logo_url($maxwidth, $maxheight);
11 * $OUTPUT->get_compact_logo_url($maxwidth, $maxheight);
14 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
15 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
16 the theme/ directory BEFORE UPGRADING.
17 * CLI svgtool.php has moved from theme/base/cli to admin/cli and paths should be relative to the new location.
18 * Bootstrap 4 was added as part of a the new theme 'boost'.
19 * Themes can now automatically compile SCSS on the fly. This works the same way as it
20 does compiling LESS on the fly, effecitvely adding $THEME->scssfile to your config.
21 * Two new callbacks allow themes to inject SCSS code before and after the content provided
22 by the SCSS file $THEME->scssfile. See $THEME->prescsscallback and $THEME->extrascsscallback.
23 * Using .dir-rtl for RTL styling is deprecated and should not be used any more. From now
24 the styles are automatically flipped when the language is right-to-left. However,
25 as this is not always perfect, you can define exceptions. Please refer to the documentation
26 of the tool RTLCSS-PHP for more information: https://github.com/moodlehq/rtlcss-php
27 * The class .dir-ltr should not be used any more. To force LTR styles use the directive
28 to remove the rule when the language is RTL. See RTLCSS-PHP for more information.
29 * A new class .text-ltr may be used to force the direction to LTR. This is especially useful
30 for forms fields (numbers, emails, URLs must not be RTL'd), and for displaying code
31 snippets or configuration samples.
32 * A new callback can be defined to post process the CSS using an object representation
33 of the CSS tree ($THEME->csstreepostprocess). This gives a lot more flexibility than a
34 simplel find and replace. Refer to 'boost' for an example, and to PHP-CSS-Parser
35 (https://github.com/sabberworm/PHP-CSS-Parser) for the API.
36 * You may no longer override the following core_course_renderer methods.
37 See course/upgrade.txt for more information:
38 - course_modchooser_module_types
39 - course_modchooser_module
40 - course_modchooser_title
41 * The question chooser now uses a renderable and a template, the following methods
42 have been deprecated in favour of core_question_bank_renderer::render_qbank_chooser().
47 * The 'css optimiser' has been removed. Developers are encouraged to use tools such as stylelint
48 to help optimise their css. Some functions and classes in lib/csslib.php (which was not for public use)
53 - class css_optimiser no longer does anything.
57 * A new search box for global search has been added to bootstrap and clean layout files, if
58 your theme is overwriting columns1.php, columns2.php or columns3.php you will need to add a
59 call to core_renderer::search_box to display it.
60 * Notification templates have been renamed to better suit types of alert
61 rather than uses. The following changes have been made:
62 * notification_problem.mustache => notification_error.mustache
63 * notification_message => notification_info
64 * notification_redirect => notification_warning
65 * Method core_course_renderer::course_section_cm_name() is split into two methods, custom themes that override
66 this method must be modified or otherwise editing functionality may become broken. This method is now also used by
67 social activities block and site menu block to display activities names.
71 * The renderer function core_availability_renderer::multiple_messages was changed to
72 render_core_availability_multiple_messages, requiring a parameter of the new
73 \core_availability\multiple_messages type.
74 * Meta description is now included in standard_head_html for homepage in bootstrapbase.
75 If your theme includes a meta description directly in a layout for the frontpage,
76 you will need to remove it or override the standard_head_html instead.
77 * Themes Clean and More have been updated to use a new navbar_button function, which shows the
78 hamburguer icon (responsive menu) or not depending on custom and language menus settings;
79 themes extending bootstrapbase and overriding its layouts can call replace their "a.btn-navbar"
80 node for a call to this function.
81 * Themes Clean and More page header logo only displays on front page and login page.
82 * A new function navbar_home has been added to theme_clean and theme_more to display the navigation bar link
83 to the site home. Two new settings have been added to control if the link should be a small logo image, text
84 or both. It defaults to the current behaviour, only a text link.
88 * Themes Bootstrapbase, Clean and More have undergone some changes for RTL layouts see - MDL-48160.
90 * Themes Clean amd More page header background logo, if loaded, no longer links to the home page.
91 * Themes Clean and More have been updated to use the renderer full_header(). This renderer (when in a user context) displays a message button
92 and consequently the link to message users have been removed from various pages. It is recommended that theme developers use this
93 renderer to ensure that they do not suffer from a reduction in access to this feature.
94 * $OUTPUT->context_header() has been introduced to produce headers similar to what full_header() creates. This renderer is used for creating
95 subsequent headers in a page. If provided with user information, this render will also display a message button like full_header().
99 * Themes Base and Canvas layout/embedded.php has changed.
100 The div id="content" has been changed to id="page-content" - see MDL-47915.
101 * All mod_assign CSS selectors have been qualified with ".path-mod-assign". This means any custom CSS
102 rules for mod_assign in a theme may need to be updated.
103 * The following render methods were renamed, if you have overridden any of these you will need to update your renderer:
104 - report_log_renderer::render_report_log_renderable => report_log_renderer::render_report_log
105 - report_loglive_renderer::render_report_loglive_renderable => report_loglive_renderer::render_report_log
106 * On calendar view screen the course selector and new event button have been swapped, custom CSS for .path-calendar might be affected.
107 * The functions search_listing() and search_pagination() in the core_course_management_renderer class take the searched string
108 as an extra parameter - see MDL-46902.
109 * Themes with non-fixed headers must have the .navbar class in their navbar in order for floating headers in the grader report to work - see MDL-46658.
110 * To accomodate the new gradebook, use of overflow: hidden or overflow-x: hidden CSS rules on DOM elements containing the
111 #user-grades table, visible at [Course administration -> Grades] is not recommended. Please use overflow: auto or
112 overflow: scroll instead, as this will handle medium to large courses with multiple activities better (more information available at https://docs.moodle.org/dev/Theme_upgrade_notes ).
113 * The new user menu can be added to themes by calling $OUTPUT->user_menu(); we recommend doing so in a backwards-compatible way (see https://docs.moodle.org/dev/Theme_upgrade_notes for more information).
117 * CSS related functions in theme class and csslib.php were refactored, addons that are
118 using this private API need to be updated
119 * Please update your css to use 'tr:nth-of-type(odd/even)' instead of '.r0/.r1' to apply tr specific css for various tables.
120 These classes are deprecated now and will be removed in Moodle 2.9. This has done to better support styling tables that will be altered by JavaScript.
121 Here is an example to update your css:
123 table.generaltable .r0 {background-color: #F0F0F0;}
124 table.generaltable .r1 {background-color: #F0F0F0;}
126 table.generaltable > tbody > tr:nth-of-type(even) {background-color: #F0F0F0;}
127 table.generaltable > tbody > tr:nth-of-type(odd) {background-color: #F0F0F0;}
130 * afterburner, anomaly, arialist, binarius, boxxie, brick, formal_white, formfactor, fusion, leatherbound,
131 magazine, nimble, nonzero, overlay, serenity, sky_high, splash, standard and standardold have been removed.
132 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
133 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
134 the theme/ directory BEFORE UPGRADING.
137 * z-index on #dock has been adjusted from 11000 to 5000 to prevent overlapping issues with fullscreen TinyMCE in Base theme.
142 * "My Mobile" theme has been removed (see MDL-40874).
143 During the upgrade process "My Mobile" theme will be uninstalled and all its settings will be deleted.
144 "My Mobile" theme and its extending themes will fallback to the mobile friendly "Clean" theme.
145 If you wish to keep "My Mobile" theme and its settings, BEFORE UPGRADING you can copy the files from the
146 unmaintained plugin into theme/mymobile.
147 The unmaintained plugin can be downloaded at https://moodle.org/plugins/pluginversion.php?id=4563
149 * There have been several changes made to the classes used on headings throughout Moodle.
150 This was done as per the Moodle HTML guidelines. h1 and h2 elements should have no classes, h3 and lower headings
151 may have descriptive classes only (any classes must properly describe the relation between the header and its content).
152 * The parameters value for the following functions have been modified: core_renderer::heading() and core_renderer::heading_with_help().
153 This means that headings using the default options will no longer have the class "main" which was the previous default.
154 * The file picker and activity chooser have been converted to use M.core.dialogue. This means the styles
155 for these elements have changed in the base and bootstrapbase themes and you will need to copy the new styles
156 if you are not inheriting from either one of these themes.
157 * For the themes based on bootstrapbase please also read theme/bootstrapbase/upgrade.txt
158 * A new component action_menu is now used to display editing icons for courses and blocks within a drop down. If you have a theme that doesn't
159 extend base, canvas, or clean then you will need to style for this new component within your theme.
160 * The maintenance layout now has a special renderer that extends the core_renderer in order to prevent some methods from interacting
161 with the database. Please be aware that for the maintenance layout some methods now always return an empty string.
162 This has been done because it is important that during maintenance routines we don't show any links, interact with the database,
163 or interact with caches as doing so may lead to errors,
164 Please see the maintenance renderer notes below for details on the functions affected.
167 * core_course_renderer::course_section_cm_edit_actions has two new optional arguments and now uses and action_menu component.
168 * core_course_renderer::course_section_cm has been altered to call core_course_renderer::course_section_cm_edit_actions with the two new arguments.
169 * core_renderer::block_controls has a new optional argument (the block id) and has been altered to use the new action_menu component.
170 * core_renderer::block_header has been altered to give core_renderer::block_controls the new second argument, the block id.
171 * core_renderer::action_link has a new argument, and optional icon that can be rendererd into the link.
174 * Changes to the classes given to the header produced when rendering a single section within a course.
175 .section-navigation.header.headingblock => .section-navigation.navigationtitle
176 * Changes to the classes used when producing the course information box that lists courses.
177 The name (h3|div} of both courses and categories used to have .name, for courses in the list this was changed to .coursename and for categories in the list this was changed to .categoryname.
178 * Classes ".header and .headingblock" were removed from all front page content headings.
179 * Classes ".headingblock .header .tag-header" were removed from the tag index page
181 Maintenance renderer notes:
182 When the maintenance layout is being used $OUTPUT will be an instance of core_renderer_maintenance.
183 This renderer mimics the core_renderer except that the following functions always return an empty string.
184 * core_renderer_maintenance::block
185 * core_renderer_maintenance::blocks
186 * core_renderer_maintenance::blocks_for_regions
187 * core_renderer_maintenance::course_header
188 * core_renderer_maintenance::course_footer
189 * core_renderer_maintenance::course_content_header
190 * core_renderer_maintenance::course_content_footer
191 * core_renderer_maintenance::custom_menu
192 * core_renderer_maintenance::file_picker
193 * core_renderer_maintenance::htmllize_file_tree
194 * core_renderer_maintenance::lang_menu
195 * core_renderer_maintenance::login_info
196 * core_renderer_maintenance::user_picture
198 If you have overridden methods of the core_renderer in your theme and want those changes to be shown during times of maintenance you
199 will also need to override the core_renderer_maintenance and copy your customisations from the core_renderer to that.
204 * Block drag and drop functionality has been improved so that it works regardless of what block regions you use
205 or how many block regions you have. In order to benefit from this improvement you must convert your calls from
206 $OUTPUT->blocks_for_region() to $OUTPUT->blocks.
209 * Theme config can nominate block regions to swap if the user is using a rtl languages such as Hebrew.
210 $THEME->blockrtlmanipulations should be an associative array, the key is the original block region, and the
211 value should be where the blocks in that region should be displayed.
212 * New $OUTPUT methods to replace code that was previously using $PAGE. Converting to these methods is optional
213 but highly recommended. Refer to the bootstrapbase layouts for examples.
214 - $OUTPUT->body_attributes() returns a string you can use for the body id and classes.
215 - $OUTPUT->blocks() returns HTML to display a block region and all of its blocks. This adds data attributes
216 that ensure drag and drop of blocks will work no matter what block regions or how many you have.
217 - $OUTPUT->page_heading() returns the page heading. Replaces $PAGE->heading.
218 - $OUTPUT->page_heading_button() returns the button to display with the heading. Replaces $page->button.
219 - $OUTPUT->page_doc_link() returns the link to moodle docs for the page. Replaces page_doc_link().
220 - $OUTPUT->page_heading_menu() returns the heading menu for the page. Replaces $PAGE->headingmenu.
221 - $OUTPUT->page_title() Returns the title to use for the head section.
222 - $OUTPUT->favicon() returns the URL to the favicon.
225 * core_renderer::navbar now returns an empty string if there are no navigation items to display.
226 * core_renderer::custom_menu now adds a class "custom_menu" to the div that contains the HTML for the custom menu.
231 * Functions core_course_renderer::course_category_tree() and course_category_tree_category()
233 * Significant changes in rendering of courses and categories listings, lots of CSS classes changed,
234 several functions such as print_courses(), print_whole_category_list(), print_category_info()
235 are moved to course renderer.
236 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
239 * changed the h1 title in the help popup to a h2.
240 * new setting $THEME->yuicssmodules = array('cssreset', 'cssfonts', 'cssgrids', 'cssbase'); which
241 allows themes to use different CSS reset normalisers such as cssnormalize YUI module.
242 * Re-wrote the user profile views to definition lists.
243 * Re-wrote the table for the course completion status block to use html_table - added some CSS classes to
244 the table in the process (see MDL-35608).
245 * Cancel buttons have the class btn-cancel.
246 * Added a z-index for the div#dateselector-calendar-panel so that the calendar pop-up renders above
247 the filemanager when they overlap, ie. the course settings page (see MDL-39047).
248 * Trivial change of CSS selectors used to display plugin status at the plugins overview
249 screen (#plugins-control-panel).

257 * output course and course content header/footer that may be returned by course format (see MDL-36048)
258 * span.completionprogress has been changed to a <div> and is not a float by default any more.

266 * c/group: Use i/groupevent instead
267 * c/site: Use i/siteevent instead
268 * c/user: Use i/userevent instead
269 * t/clear: Use t/check instead
270 * i/cross_red_big: Use i/invalid or i/grade_incorrect

272 * i/tick_amber_big: Use i/caution or i/grade_partiallycorrect
273 * No more small versions of i/cross_red_small, i/tick_green_small and i/tick_amber_small, use their big equivalent.

280 * new class 'iconlarge' for 24x24 icons.
281 * new icons i/export and i/import (sized 16x16). Previously export and import actions used i/backup and i/restore.
