class Puppet::Pops::Parser::EppParser

The EppParser is a specialized Puppet Parser that starts parsing in Epp Text mode

Public Instance Methods

_parse() click to toggle source

Performs the parsing and returns the resulting model. The lexer holds state, and this is setup with {#parse_string}, or {#parse_file}.

TODO: deal with options containing origin (i.e. parsing a string from externally known location). TODO: should return the model, not a Hostclass

initvars() click to toggle source

Initializes the epp parser support by creating a new instance of {Puppet::Pops::Parser::Lexer} configured to start in Epp Lexing mode. @return [void]

   # File lib/puppet/pops/parser/epp_parser.rb
 9 def initvars
10   self.lexer = Puppet::Pops::Parser::Lexer2.new()
11 end

parse_file(file) click to toggle source

Parses a file expected to contain epp text/DSL logic.

   # File lib/puppet/pops/parser/epp_parser.rb
14 def parse_file(file)
15   unless FileTest.exist?(file)
16     unless file =~ /\.epp$/
17       file = file + ".epp"
18     end

20   @lexer.file = file
