If a copy of the MPL was not distributed with this +# file, You can obtain one at http://mozilla.org/MPL/2.0/. */ + +# This file defines static prefs, i.e. those that are defined at startup and +# used entirely or mostly from C++ and/or Rust code. +# +# The file is separated into sections, where each section contains a group of +# prefs that all share the same first segment of their name -- all the "gfx.*" +# prefs are together, all the "network.*" prefs are together, etc. Sections +# must be kept in alphabetical order, but prefs within sections need not be. +# +# Basics +# ------ +# Any pref defined in one of the files included here should *not* be defined +# in a data file such as all.js; that would just be useless duplication. +# +# (Except under unusual circumstances where the value defined here must be +# overridden, e.g. for some Thunderbird prefs. In those cases the default +# value from the data file will override the static default value defined +# here.) +# +# Please follow the existing prefs naming convention when considering adding a +# new pref, and don't create a new pref group unless it's appropriate and there +# are likely to be multiple prefs within that group. (If you do, you'll need to +# update the `pref_groups` variable in modules/libpref/moz.build.) +# +# Definitions +# ----------- +# A pref definition looks like this: +# +# - name: # mandatory +# type: # mandatory +# value: # mandatory +# mirror: # mandatory +# do_not_use_directly: # optional +# include: # optional +# rust: # optional +# +# - `name` is the name of the pref, without double-quotes, as it appears +# in about:config. It is used in most libpref API functions (from both C++ +# and JS code). +# +# - `type` is one of `bool`, `int32_t`, `uint32_t`, `float`, an atomic version +# of one of those, `String` or `DataMutexString`. Note that float prefs are +# stored internally as strings. The C++ preprocessor doesn't like template +# syntax in a macro argument, so use the typedefs defined in +# StaticPrefsBase.h; for example, use `RelaxedAtomicBool` instead of +# `Atomic`. +# +# - `value` is the default value. Its type should be appropriate for +# , otherwise the generated code will fail to compile. A complex +# C++ numeric expressions like `60 * 60` (which the YAML parser cannot treat +# as an integer or float) is treated as a string and passed through without +# change, which is useful. +# +# - `mirror` indicates how the pref value is mirrored into a C++ variable. +# +# * `never`: There is no C++ mirror variable. The pref value can only be +# accessed via the standard libpref API functions. +# +# * `once`: The pref value is mirrored into a variable at startup; the +# mirror variable is left unchanged after that. (The exact point at which +# all `once` mirror variables are set is when the first `once` mirror +# variable is accessed, via its getter function.) This is mostly useful for +# graphics prefs where we often don't want a new pref value to apply until +# restart. Otherwise, this update policy is best avoided because its +# behaviour can cause confusion and bugs. +# +# * `always`: The mirror variable is always kept in sync with the pref value. +# This is the most common choice. +# +# When a mirror variable is present, a getter will be created that can access +# it. Using the getter function to read the pref's value has the two +# following advantages over the normal API functions. +# +# * A direct variable access is faster than a hash table lookup. +# +# * A mirror variable can be accessed off the main thread. If a pref *is* +# accessed off the main thread, it should have an atomic type. Assertions +# enforce this. +# +# Note that Rust code must access the mirror variable directly, rather than +# via the getter function. +# +# - `do_not_use_directly` indicates if `_DoNotUseDirectly` should be appended to +# the name of the getter function. This is simply a naming convention +# indicating that there is some other wrapper getter function that should be +# used in preference to the normal static pref getter. Defaults to `false` if +# not present. Cannot be used with a `never` mirror value, because there is +# no getter function in that case. +# +# - `include` names a header file that must be included for the pref value to +# compile correctly, e.g. because it refers to a code constant. System +# headers should be surrounded with angle brackets, e.g. ``. +# +# - `rust` indicates if the mirror variable is used by Rust code. If so, it +# will be usable via the `static_prefs::pref!` macro, e.g. +# `static_prefs::pref!("layout.css.font-display.enabled")`. +# +# The getter function's base name is the same as the pref's name, but with +# '.' or '-' chars converted to '_', to make a valid identifier. For example, +# the getter for `foo.bar_baz` is `foo_bar_baz()`. This is ugly but clear, +# and you can search for both the pref name and the getter using the regexp +# /foo.bar.baz/. Suffixes are added as follows: +# +# - If the `mirror` value is `once`, `_AtStartup` is appended, to indicate the +# value was obtained at startup. +# +# - If the `do_not_use_directly` value is true, `_DoNotUseDirectly` is +# appended. +# +# Preprocessor +# ------------ +# Note finally that this file is preprocessed by preprocessor.py, not the C++ +# preprocessor. As a result, the following things may be surprising. +# +# - YAML comments start with a '#', so putting a comment on the same line as a +# preprocessor directive is dubious. E.g. avoid lines like `#define X 3 # +# three` because the ` # three` will be part of `X`. +# +# - '@' use is required for substitutions to occur. E.g. with `#define FOO 1`, +# `FOO` won't be replaced with `1` unless it has '@' chars around it. +# +# - Spaces aren't permitted between the leading '#' and the name of a +# directive, e.g. `#ifdef XYZ` works but `# ifdef XYZ` does not. +# +# Please indent all prefs defined within #ifdef/#ifndef conditions. This +# improves readability, particular for conditional blocks that exceed a single +# screen. But note that the leading '-' in a definition must remain in the +# first column for it to be valid YAML. + +#ifdef RELEASE_OR_BETA +#define IS_NOT_RELEASE_OR_BETA false +#else +#define IS_NOT_RELEASE_OR_BETA true +#endif + +#ifdef NIGHTLY_BUILD +#define IS_NIGHTLY_BUILD true +#define IS_NOT_NIGHTLY_BUILD false +#else +#define IS_NIGHTLY_BUILD false +#define IS_NOT_NIGHTLY_BUILD true +#endif + +#if defined(NIGHTLY_BUILD) || defined(MOZ_DEV_EDITION) +#define IS_NIGHTLY_OR_DEV_EDITION true +#else +#define IS_NIGHTLY_OR_DEV_EDITION false +#endif + +#ifdef MOZILLA_OFFICIAL +#define IS_NOT_MOZILLA_OFFICIAL false +#else +#define IS_NOT_MOZILLA_OFFICIAL true +#endif + +#ifdef EARLY_BETA_OR_EARLIER +#define IS_EARLY_BETA_OR_EARLIER true +#define IS_NOT_EARLY_BETA_OR_EARLIER false +#else +#define IS_EARLY_BETA_OR_EARLIER false +#define IS_NOT_EARLY_BETA_OR_EARLIER true +#endif + +#ifdef ANDROID +#define IS_ANDROID true +#define IS_NOT_ANDROID false +#else +#define IS_ANDROID false +#define IS_NOT_ANDROID true +#endif + +#ifdef XP_WIN +#define IS_XP_WIN true +#define IS_NOT_XP_WIN false +#else +#define IS_XP_WIN false +#define IS_NOT_XP_WIN true +#endif + +#--------------------------------------------------------------------------- +# Prefs starting with "accessibility." +#--------------------------------------------------------------------------- + +- name: accessibility.accesskeycausesactivation + type: bool + value: true + mirror: always + +- name: accessibility.monoaudio.enable + type: RelaxedAtomicBool + value: false + mirror: always + +- name: accessibility.browsewithcaret + type: RelaxedAtomicBool + value: false + mirror: always + +- name: accessibility.AOM.enabled + type: bool + value: false + mirror: always + +- name: accessibility.ARIAReflection.enabled + type: bool + value: @IS_NIGHTLY_BUILD@ + mirror: always + +# Whether form controls and images should be focusable with mouse, in content +# documents. +# +# This matches historical macOS / Safari behavior. +# +# * 0: never +# * 1: always +# * 2: on content documents +- name: accessibility.mouse_focuses_formcontrol + type: int32_t +#ifdef XP_MACOSX + value: 2 +#else + value: 1 +#endif + mirror: always + +# Whether to avoid accessibility activation on Windows shortly after clipboard +# copy. +# +# Possible values are: +# * 0: never +# * 1: always +# * 2 (or others): when needed +- name: accessibility.windows.suppress-after-clipboard-copy + type: uint32_t + value: 2 + mirror: always + +#--------------------------------------------------------------------------- +# Prefs starting with "alerts." +#--------------------------------------------------------------------------- + +# Whether to use platform-specific backends for showing desktop notifications. +# If no such backend is available, or if the pref is false, then XUL +# notifications are used. +- name: alerts.useSystemBackend + type: bool + value: true + mirror: always + +#if defined(XP_WIN) + # On Windows, a COM Surrogate notification server receives notification events + # and can relaunch the application after it has been closed. +- name: alerts.useSystemBackend.windows.notificationserver.enabled + type: bool + value: true + mirror: never +#endif + +#ifdef ANDROID + #--------------------------------------------------------------------------- + # Prefs starting with "android." + #--------------------------------------------------------------------------- + + # On Android, we want an opaque background to be visible under the page, + # so layout should not force a default background. +- name: android.widget_paints_background + type: RelaxedAtomicBool + value: true + mirror: always + +- name: android.touch_resampling.enabled + type: RelaxedAtomicBool + value: true + mirror: always + +#endif + +#--------------------------------------------------------------------------- +# Prefs starting with "apz." +# The apz prefs are explained in AsyncPanZoomController.cpp +#--------------------------------------------------------------------------- + +# amount we zoom in for a double tap gesture if we couldn't find any content +# based rect to zoom to +- name: apz.doubletapzoom.defaultzoomin + type: AtomicFloat + value: 1.2f + mirror: always + +- name: apz.scrollbarbuttonrepeat.enabled + type: RelaxedAtomicBool + value: true + mirror: always + +- name: apz.scrollend-event.content.enabled + type: RelaxedAtomicBool + value: true + mirror: always + +# After a user has executed a pan gesture, we may receive momentum phase pan +# gestures from the OS.
