# Files
# .gclient : Current client configuration, written by 'config' command.
# Format is a Python script defining 'solutions', a list whose
# entries each are maps binding the strings "name" and "url"
# to strings specifying the name and location of the client
# module, as well as "custom_deps" to a map similar to the
# deps section of the DEPS file below, as well as
# "custom_hooks" to a list similar to the hooks sections of
# the DEPS file below.
# .gclient_entries : A cache constructed by 'update' command. Format is a
# Python script defining 'entries', a list of the names
# of all modules in the client
# <module>/DEPS : Python script defining var 'deps' as a map from each
# requisite submodule name to a URL where it can be found (via
# one SCM)
# Hooks
# .gclient and DEPS files may optionally contain a list named "hooks" to
# allow custom actions to be performed based on files that have changed in the
# working copy as a result of a "sync"/"update" or "revert" operation. This
# can be prevented by using --nohooks (hooks run by default). Hooks can also
# be forced to run with the "runhooks" operation. If "sync" is run with
# --force, all known but not suppressed hooks will run regardless of the state
# of the working copy.
# Each item in a "hooks" list is a dict, containing these two keys:
# "pattern" The associated value is a string containing a regular
# expression. When a file whose pathname matches the expression
# is checked out, updated, or reverted, the hook's "action" will
# run.
# "action" A list describing a command to run along with its arguments, if
# any. An action command will run at most one time per gclient
# invocation, regardless of how many files matched the pattern.
# The action is executed in the same directory as the .gclient
# file. If the first item in the list is the string "python",
# the current Python interpreter (sys.executable) will be used
# to run the command. If the list contains string
# "$matching_files" it will be removed from the list and the list
# will be extended by the list of matching files.
# "name" An optional string specifying the group to which a hook belongs
# for overriding and organizing.
# Example:
# hooks = [
# { "pattern": "\\.(gif|jpe?g|pr0n|png)$",
# "action": ["python", "", "--all"]},
# { "pattern": ".",
# "name": "gyp",
# "action": ["python", "src/build/gyp_chromium"]},
# ]
# Pre-DEPS Hooks
# DEPS files may optionally contain a list named "pre_deps_hooks". These are
# the same as normal hooks, except that they run before the DEPS are
# processed. Pre-DEPS run with "sync" and "revert" unless the --noprehooks
# flag is used.
# Specifying a target OS
# An optional key named "target_os" may be added to a gclient file to specify
# one or more additional operating systems that should be considered when
# processing the deps_os/hooks_os dict of a DEPS file.
# Example:
# target_os = [ "android" ]
# If the "target_os_only" key is also present and true, then *only* the
# operating systems listed in "target_os" will be used.
# Example:
# target_os = [ "ios" ]
# target_os_only = True
# Specifying a target CPU
# To specify a target CPU, the variables target_cpu and target_cpu_only
# are available and are analagous to target_os and target_os_only.
