NAME

masontidy - Tidy HTML::Mason / Mason components

VERSION

version 2.55

SYNOPSIS

Tidy component, write to standard output:

% masontidy -m [1|2] file.mc

Tidy component(s) in place:

% masontidy -m [1|2] -r file1.mc [file2.mc ...]

Tidy standard input, write to standard output:

% masontidy -m [1|2] -p|--pipe < file.mc

DESCRIPTION

masontidy tidies Mason 1 and Mason 2 components, using perltidy to format the Perl code that can be embedded in various places in the component. masontidy does not (yet) attempt to tidy the HTML or other non-Perl content in a component.

For example, this:

<body>
%if($contents||$allow_empty) {
  <ul>
%foreach my $line (@lines) {
%chomp($line);
  <li>
      <%2+(3-4)*6%>
  </li>
  <li><%  foo($.bar,$.baz,  $.bleah)%></li>
%}
  </ul>
%}
</body>

<%init>
my @articles = @{Blog::Article::Manager->get_articles(sort_by=>"create_time",limit=>5)};
</%init>

becomes this:

<body>
% if ( $contents || $allow_empty ) {
  <ul>
%     foreach my $line (@lines) {
%         chomp($line);
  <li>
      <% 2 + ( 3 - 4 ) * 6 %>
  </li>
  <li><% foo( $.bar, $.baz, $.bleah) %></li>
%     }
  </ul>
%}
</body>

<%init>
my @articles =
  @{ Blog::Article::Manager->get_articles
     ( sort_by => "create_time", limit => 5 ) };
</%init>

What gets tidied

  • %-lines and <%perl> blocks. These are indented relative to each other regardless of intervening non-Perl content, e.g. note the indentation of the foreach and chomp lines above.

  • Other code blocks. <%init>, <%once>, <%class>, and <%filter> blocks are tidied in isolation from one another.

  • Perl expressions inside <% %> and <& &> tags.

INVOKING

There are three ways of invoking masontidy:

  • Specify a single file; the result will be written to standard output.

  • Specify one or more files with the -r/--replace flag; each file will be tidied in place.

  • Specify -p/--pipe; content from standard input will be tidied and written to standard output.

For more advanced options, consider using masontidy with tidyall; it will let you write to files with a separate extension, backup files before overwriting, etc.

COMMAND-LINE OPTIONS

You can specify default options in the MASONTIDY_OPT environment variable, e.g.

MASONTIDY_OPT="-m 2"
-m, --mason-version

Mason major version - 1 or 2. Required. Put this in MASONTIDY_OPT if you only ever use one version on your system.

-r, --replace

Modify file(s) in place instead of sending to standard output.

--indent-perl-block

Number of spaces to initially indent all lines inside <%perl> blocks. The default is 2, so as to align with %-lines:

% my $foo = get_foo();
<%perl>
  if ($foo) {
      $bar = 6;
  }
</%perl>

With --indent-perl-block 0:

% my $foo = get_foo();
<%perl>
if ($foo) {
    $bar = 6;
}
</%perl>

Note that this is independent from perltidy's indentation settings.

--indent-block

Number of spaces to initially indent all lines inside code blocks other than <%perl> (<%init>, <%class>, <%once>, and <%filter>). The default is 0:

<%init>
if ($foo) {
    $bar = 6;
}
</%init>

With --indent-block 2:

<%init>
  if ($foo) {
      $bar = 6;
  }
</%init>
--perltidy-argv

perltidy arguments to use everywhere. e.g.

--perltidy-argv="-noll -l=78"

or

--perltidy-argv " -noll -l=78"
--perltidy-line-argv

Additional perltidy arguments to use for Perl lines.

--perltidy-block-argv

Additional perltidy arguments to use for code blocks.

--perltidy-tag-argv

Additional perltidy arguments to use for <% %> and <& &> tags. For example, to ensure that these tags are never broken out onto multiple lines regardless of how long they are:

--perltidy-tag-argv="-fnl"  # short for --freeze-newlines
-h, --help

Print help message

ERRORS

Will throw a fatal error if a file cannot be tidied, such as when perltidy encounters bad Perl syntax. However, masontidy is not intended to be, and should not be considered, a validator; it will remain silent on many syntax errors.

LIBRARY API

You can use the Mason::Tidy API from inside another Perl script/library instead of calling out to this script.

CAVEATS / KNOWN BUGS

  • <%perl> and </%perl> tags must be on their own line, or else their inner content will not be tidied.

  • <% %> tags that span multiple lines are ignored.

  • The line structure of %-lines, <% %> tags, and <%perl> blocks will not be altered; i.e. multiple lines will not be merged and single lines will not be split, regardless of their length.
