Instance Method Summary

• #accepts(langs = []) ⇒ Query

  Check if the browser accepts the specified languages.

• #is(names = [], versions = {}, platforms = []) ⇒ Query

  Checks if the browser is a specific name and optionally of a specific version and platform.

Instance Method Details

#accepts(langs = []) ⇒ Query

Check if the browser accepts the specified languages.

Parameters:

• langs (String|Array) (defaults to: []) —

  A list of languages to match against.

Returns:

• (Query) —

  A query which can evaluated for concatenation or result.

# File 'lib/brauser/browser.rb', line 621

def accepts(langs = [])
  self.parse_accept_language(@accept_language) if !@languages
  ::Brauser::Query.new(self, (@languages & langs.ensure_array.uniq.compact.collect {|l| l.to_s }).present?)
end

#is(names = [], versions = {}, platforms = []) ⇒ Query

Checks if the browser is a specific name and optionally of a specific version and platform.

Parameters:

• names (Symbol|Array) (defaults to: []) —

  A list of specific names to match. Also, this meta-names are supported: :capable and :tablet.

• versions (String|Hash) (defaults to: {}) —

  A string in the form operator version && ... (example: >= 7 && < 4) or an hash with specific version to match against, in form {:operator => version}, where operator is one of :lt, :lte, :eq, :gt, :gte.

• platforms (Symbol|Array) (defaults to: []) —

  A list of specific platform to match. Valid values are all those possible for the platform attribute.

Returns:

• (Query) —

  A query which can evaluated for concatenation or result.

• #v?
• #on?

def is(names = [], versions = {}, platforms = [])
  self.parse_agent(@agent) if !@name

  names = adjust_names(names)
  versions = parse_versions_query(versions)
  platforms = platforms.ensure_array

  ::Brauser::Query.new(self,
    (names.blank? || (names.include?(@name) && check_capable(names))) &&
    (versions.blank? || self.v?(versions)) &&
    (platforms.blank? || self.on?(platforms))
  )
end

#on(platforms = []) ⇒ Query

Check if the browser is on a specific platform.

Parameters:

• platforms (Symbol|Array) (defaults to: []) —

  A list of specific platform to match.

Returns:

• (Query) —

  A query which can evaluated for concatenation or result.

# File 'lib/brauser/browser.rb', line 612

def on(platforms = [])
  self.parse_agent(@agent) if !@platform
  ::Brauser::Query.new(self, platforms.blank? || platforms.ensure_array.uniq.compact.collect {|p| p.ensure_string.to_sym }.include?(@platform))
end

#v(versions = {}) ⇒ Query

Checks if the browser is a specific version.

Parameters:

• versions (String|Hash) (defaults to: {}) —

  A string in the form operator version && ... (example: >= 7 && < 4) or an hash with specific version to match against, in form {:operator => version}, where operator is one of :lt, :lte, :eq, :gt, :gte.

Returns:

• (Query) —

  A query which can evaluated for concatenation or result.

# File 'lib/brauser/browser.rb', line 594

def v(versions = {})
  self.parse_agent(@agent) if !@version

  versions = if versions.is_a?(String) then
    parse_versions_query(versions)
  elsif !versions.is_a?(::Hash) then
    {}
  else
    versions
  end

  ::Brauser::Query.new(self, versions.all? { |operator, value| Brauser::Browser.compare_versions(@version, operator, value) })
end
