NAME

       Verilog::EditFiles - Split Verilog modules into separate files.

SYNOPSIS

       See splitmodule command.

          use Verilog::EditFiles;
          my $split = Verilog::EditFiles->new
              (outdir => "processed_rtl",
               translate_synthesis => 0,
               lint_header => undef,
               celldefine => 1,
               );
          $split->read_and_split(glob("inbound_rtl/*.v"));
          $split->write_files();
          $split->edit_file(filename=>"foo", cb => sub { return $_[0]; });

DESCRIPTION

       Verilog::EditFiles provides a easy way to split library Verilog files that contain
       multiple modules into many files with one module per file.

FUNCTIONS

       new (...)
           Create a new Verilog::EditFiles object.  Named parameters may be specified:

           celldefine
               If true, add "`celldefine" before every module statement.

           lint_command
               For the write_lint method, the name of the linter to use.  Defaults to "vlint
               --brief".

           lint_header
               If defined, add the provided text before every module statement.  Generally used
               to insert lint off pragmas.

           outdir
               Name of the directory to write the output modules to.  Defaults to ".".

           program
               Name of the program to add to comments.  Defaults to "Verilog::EditFiles".

           timescale_header
               If defined, add the provided text before every module statement.  Generally set to
               the next needed to #include a timescale file.  Use with timescale_removal.

           timescale_removal
               If set, remove any `timescales.

           translate_synthesis
               If 1, replace any synopsys translate on/offs with "`ifdef SYNTHESIS" and
               "`endif"s.  If set to a string, use that string instead of "SYNTHESIS".

           v_suffix
               The suffix to add to convert a module name into a filename.  Defaults to ".v".

           verbose
               If true, print what files are being read and written.

       $self->read_and_split([filenames])
           Read from the specified filenames.

           If there is no module statement in the file, assume it is a include file, and when
           write_files is called, place all of the file contents into the output.  If there is a
           module statement, when write_files is called place all following output into a file
           named based on the module, with .v added.

       $self->write_files()
           Write all of the files created by read_and_split to the outdir.

       $self->write_lint([filename=>...])
           Create a shell script that will lint every file created by write_files.  If a
           "filename" parameter is not provided, "0LINT.sh" will be written in the default
           outdir.

       $self->edit_file(filename=>..., cb=>sub{...})
           Read a file, edit it with the provided callback, and save it if it has changed.  The
           "filename" parameter is the filename to read.  The "write_filename" parameter is the
           filename to write, defaulting to the same name as the filename to read.  The "cb"
           parameter is a reference to a callback which takes the string of file contents and
           returns the string to write back.  Often the callback will simply perform a search and
           replace.
