NAME
Verilog::Getopt - Get Verilog command line options
SYNOPSIS
use Verilog::Getopt; my $opt = new Verilog::Getopt; $opt->parameter (qw( +incdir+standard_include_directory )); @ARGV = $opt->parameter(@ARGV); ... print "Path to foo.v is ", $opt->file_path('foo.v');
DESCRIPTION
Verilog::Getopt provides standardized handling of options similar to Verilog/VCS and cc/GCC.
OPTIONS
The new() constructor accepts the following options: filename_expansion=>1 Enable converting filenames to relative filenames when possible. This option is needed when the -F option will be used. If flags are passed through Getopt which should otherwise not be expanded (e.g. "--out myfile.v") having this option set may undesirably expand myfile.v to an absolute filename. gcc_style=>0 Disable parsing of GCC-like parameters. vcs_style=>0 Disable parsing of VCS-like parameters.
METHODS
$opt = Verilog::Getopt->new ( opts ) Create a new Getopt. See OPTIONS above. $self->file_path(filename, [lookup_type]) Returns a new path to the filename, using the library directories and search paths to resolve the file. Optional lookup_type is 'module', 'include', or 'all', to use only module_dirs, incdirs, or both for the lookup. $self->get_parameters() Returns a list of parameters that when passed through $self->parameter() should result in the same state. Often this is used to form command lines for downstream programs that also use Verilog::Getopt. $self->parameter(\@params) Parses any recognized parameters in the referenced array, removing the standard parameters from any previous parameters() call, and returning a array with all unparsed parameters. The below list shows the VCS-like parameters that are supported, and the functions that are called: +libext+I<ext>+I<ext>... libext (I<ext>) +incdir+I<dir> incdir (I<dir>) +define+I<var>=I<value> define (I<var>,I<value>) +define+I<var> define (I<var>,undef) +librescan Ignored -F I<file> Parse parameters in file relatively -f I<file> Parse parameters in file -v I<file> library (I<file>) -y I<dir> module_dir (I<dir>) all others Put in returned list The below list shows the GCC-like parameters that are supported, and the functions that are called: -DI<var>=I<value> define (I<var>,I<value>) -DI<var> define (I<var>,undef) -UI<var> undefine (I<var>) -II<dir> incdir (I<dir>) -F I<file> Parse parameters in file relatively -f I<file> Parse parameters in file all others Put in returned list $self->write_parameters_file(filename) Write the output from get_parameters to the specified file.
ACCESSORS
$self->define($token, $value) This method is called when a define is recognized. The default behavior loads a hash that is used to fulfill define references. This function may also be called outside parsing to predefine values. An optional third argument specifies parameters to the define, and a fourth argument if true indicates the define was set on the command line and should not be removed by `undefineall. $self->define_names_sorted Return sorted list of all define names that currently exist. $self->defparams($token) This method returns the parameter list of the define. This will be defined, but false, if the define does not have arguments. $self->defvalue($token) This method returns the value of a given define, or prints a warning. $self->defvalue_nowarn($token) This method returns the value of a given define, or undef. $self->depend_files() Returns reference to list of filenames referenced with file_path, useful for creating dependency lists. With argument, adds that file. With list reference argument, sets the list to the argument. $self->file_abs($filename) Using the incdir and libext lists, convert the specified module or filename ("foo") to a absolute filename ("include/dir/foo.v"). $self->file_skip_special($filename) Return true if the filename is one that generally should be ignored when recursing directories, such as for example, ".", "CVS", and ".svn". $self->file_substitute($filename) Removes existing environment variables from the provided filename. Any undefined variables are not substituted nor cause errors. $self->incdir Returns reference to list of include directories. With argument, adds that directory. $self->includes Returns reference to hash of files that included some file, and for each hash value a list of files included. Only relevant after Verilog::Netlist processing. With two arguments, adds an include for the given referencing filename to the given include filename. $self->libext Returns reference to list of library extensions. With argument, adds that extension. $self->libext_matches(filename) Returns true if the passed filename matches the libext. $self->library Returns reference to list of libraries. With argument, adds that library. $self->module_dir Returns reference to list of module directories. With argument, adds that directory. $self->remove_defines($token) Return string with any definitions in the token removed. $self->undef($token) Deletes a hash element that is used to fulfill define references. This function may also be called outside parsing to erase a predefined value. $self->undefineall Deletes all non-command line definitions, for implementing `undefineall.
