NAME¶
HTML::Mason::Params - Mason configuration parameters
VERSION¶
version 1.54
DESCRIPTION¶
This document lists all of the Mason configuration parameters that are intended
to be used by end users.
PERL AND APACHE NAMES¶
Each parameter has two names: a Perl version and an Apache version. The Perl
version uses "lowercase_with_underscores", while the Apache version
uses "StudlyCaps" with a "Mason" prefix. The conversion
from one version to the other is otherwise very predictable. For example,
- •
- "autohandler_name" "<-->"
"MasonAutohandlerName"
- •
- "comp_root" "<-->"
"MasonCompRoot"
- •
- "data_cache_defaults" "<-->"
"MasonDataCacheDefaults"
Where Apache Names Are Used¶
The Apache parameter names are used in the Apache configuration file in an
httpd-based configuration.
Where Perl Names Are Used¶
The Perl parameter names are used from Perl code, i.e. anywhere other than the
Apache configuration file. For example,
- •
- In an custom wrapper-based configuration, you can pass most of these
parameters to the ApacheHandler constructor.
- •
- In a standalone Mason script, you can pass most of these parameters to the
Interp constructor.
- •
- When launching a subrequest, you can pass any of the
"HTML::Mason::Request" parameters to make_subrequest.
PARAMETERS¶
allow_globals¶
- •
- Perl name: allow_globals
- •
- Apache name: MasonAllowGlobals
- •
- Type in httpd.conf: list
- •
- Default: []
- •
- Belongs to: "HTML::Mason::Compiler"
List of variable names, complete with prefix ("$@%"), that you intend
to use as globals in components. Normally global variables are forbidden by
"strict", but any variable mentioned in this list is granted a
reprieve via a "use vars" statement. For example:
allow_globals => [qw($DBH %session)]
In a mod_perl environment, $r (the request object) is automatically added to
this list.
apache_status_title¶
- •
- Perl name: apache_status_title
- •
- Apache name: MasonApacheStatusTitle
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason status
- •
- Belongs to: "HTML::Mason::ApacheHandler"
Title that you want this ApacheHandler to appear as under Apache::Status.
Default is "HTML::Mason status". This is useful if you create more
than one ApacheHandler object and want them all visible via Apache::Status.
args_method¶
- •
- Perl name: args_method
- •
- Apache name: MasonArgsMethod
- •
- Type in httpd.conf: string
- •
- Default: mod_perl
- •
- Belongs to: "HTML::Mason::ApacheHandler"
Method to use for unpacking GET and POST arguments. The valid options are 'CGI'
and 'mod_perl'; these indicate that a "CGI.pm" or
"Apache::Request" object (respectively) will be created for the
purposes of argument handling.
'mod_perl' is the default under mod_perl-1 and requires that you have installed
the "Apache::Request" package. Under mod_perl-2, the default is
'CGI' because "Apache2::Request" is still in development.
If args_method is 'mod_perl', the $r global is upgraded to an Apache::Request
object. This object inherits all Apache methods and adds a few of its own,
dealing with parameters and file uploads. See "Apache::Request" for
more information.
If the args_method is 'CGI', the Mason request object ($m) will have a method
called "cgi_object" available. This method returns the CGI object
used for argument processing.
While Mason will load "Apache::Request" or "CGI" as needed
at runtime, it is recommended that you preload the relevant module either in
your
httpd.conf or
handler.pl file, as this will save some
memory.
- •
- Perl name: auto_send_headers
- •
- Apache name: MasonAutoSendHeaders
- •
- Type in httpd.conf: boolean
- •
- Default: 1
- •
- Belongs to: "HTML::Mason::Request::ApacheHandler"
True or false, default is true. Indicates whether Mason should automatically
send HTTP headers before sending content back to the client. If you set to
false, you should call "$r->send_http_header" manually.
See the sending HTTP headers section of the developer's manual for more details
about the automatic header feature.
NOTE: This parameter has no effect under mod_perl-2, since calling
"$r->send_http_header" is no longer needed.
autoflush¶
- •
- Perl name: autoflush
- •
- Apache name: MasonAutoflush
- •
- Type in httpd.conf: boolean
- •
- Default: 0
- •
- Belongs to: "HTML::Mason::Request"
True or false, default is false. Indicates whether to flush the output buffer
("$m->flush_buffer") after every string is output. Turn on
autoflush if you need to send partial output to the client, for example in a
progress meter.
As of Mason 1.3, autoflush will only work if enable_autoflush has been set.
Components can be compiled more efficiently if they don't have to check for
autoflush. Before using autoflush you might consider whether a few manual
"$m->flush_buffer" calls would work nearly as well.
autohandler_name¶
- •
- Perl name: autohandler_name
- •
- Apache name: MasonAutohandlerName
- •
- Type in httpd.conf: string
- •
- Default: autohandler
- •
- Belongs to: "HTML::Mason::Interp"
File name used for autohandlers. Default is "autohandler". If this is
set to an empty string ("") then autohandlers are turned off
entirely.
buffer_preallocate_size¶
- •
- Perl name: buffer_preallocate_size
- •
- Apache name: MasonBufferPreallocateSize
- •
- Type in httpd.conf: string
- •
- Default: 0
- •
- Belongs to: "HTML::Mason::Interp"
Number of bytes to preallocate in the output buffer for each request. Defaults
to 0. Setting this to, say, your maximum page size (or close to it) can reduce
the number of reallocations Perl performs as components add to the output
buffer.
code_cache_max_size¶
- •
- Perl name: code_cache_max_size
- •
- Apache name: MasonCodeCacheMaxSize
- •
- Type in httpd.conf: string
- •
- Default: unlimited
- •
- Belongs to: "HTML::Mason::Interp"
Specifies the maximum number of components that should be held in the in-memory
code cache. The default is 'unlimited', meaning no components will ever be
discarded; Mason can perform certain optimizations in this mode. Setting this
to zero disables the code cache entirely. See the code cache section of the
administrator's manual for further details.
comp_class¶
- •
- Perl name: comp_class
- •
- Apache name: MasonCompClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Component
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
The class into which component objects are blessed. This defaults to
HTML::Mason::Component.
comp_root¶
- •
- Perl name: comp_root
- •
- Apache name: MasonCompRoot
- •
- Type in httpd.conf: list
- •
- Default: Varies
- •
- Belongs to: "HTML::Mason::Interp"
The component root marks the top of your component hierarchy and defines how
component paths are translated into real file paths. For example, if your
component root is
/usr/local/httpd/docs, a component path of
/products/index.html translates to the file
/usr/local/httpd/docs/products/index.html.
Under Apache and CGI, comp_root defaults to the server's document root. In
standalone mode comp_root defaults to the current working directory.
This parameter may be either a scalar or an array reference. If it is a scalar,
it should be a filesystem path indicating the component root. If it is an
array reference, it should be of the following form:
[ [ foo => '/usr/local/foo' ],
[ bar => '/usr/local/bar' ] ]
This is an array of two-element array references, not a hash. The
"keys" for each path must be unique and their "values"
must be filesystem paths. These paths will be searched in the provided order
whenever a component path is resolved. For example, given the above component
roots and a component path of
/products/index.html, Mason would search
first for
/usr/local/foo/products/index.html, then for
/usr/local/bar/products/index.html.
The keys are used in several ways. They help to distinguish component caches and
object files between different component roots, and they appear in the
"title()" of a component.
When you specify a single path for a component root, this is actually translated
into
[ [ MAIN => path ] ]
If you have turned on dynamic_comp_root, you may modify the component root(s) of
an interpreter between requests by calling "$interp->comp_root"
with a value. However, the path associated with any given key may not change
between requests. For example, if the initial component root is
[ [ foo => '/usr/local/foo' ],
[ bar => '/usr/local/bar' ], ]
then it may not be changed to
[ [ foo => '/usr/local/bar' ],
[ bar => '/usr/local/baz' ],
but it may be changed to
[ [ foo => '/usr/local/foo' ],
[ blarg => '/usr/local/blarg' ] ]
In other words, you may add or remove key/path pairs but not modify an
already-used key/path pair. The reason for this restriction is that the
interpreter maintains a component cache per key that would become invalid if
the associated paths were to change.
compiler_class¶
- •
- Perl name: compiler_class
- •
- Apache name: MasonCompilerClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Compiler::ToObject
- •
- Belongs to: "HTML::Mason::Interp"
The class to use when creating a compiler. Defaults to
HTML::Mason::Compiler::ToObject.
component_error_handler¶
- •
- Perl name: component_error_handler
- •
- Apache name: MasonComponentErrorHandler
- •
- Type in httpd.conf: code
- •
- Default: sub { package HTML::Mason::Exceptions; use warnings; use strict
'refs'; my($err) = @_; return unless $err; if (UNIVERSAL::can($err,
'rethrow')) { $err->rethrow; } elsif (ref $err) { die $err; }
'HTML::Mason::Exception'->throw('error', $err); }
- •
- Belongs to: "HTML::Mason::Request"
A code reference used to handle errors thrown during component compilation or
runtime. By default, this is a subroutine that turns non-exception object
errors in components into exceptions. If this parameter is set to a false
value, these errors are simply rethrown as-is.
Turning exceptions into objects can be expensive, since this will cause the
generation of a stack trace for each error. If you are using strings or
unblessed references as exceptions in your code, you may want to turn this off
as a performance boost.
data_cache_api¶
- •
- Perl name: data_cache_api
- •
- Apache name: MasonDataCacheApi
- •
- Type in httpd.conf: string
- •
- Default: 1.1
- •
- Belongs to: "HTML::Mason::Request"
The "$m->cache" API to use:
- •
- '1.1', the default, indicates a "Cache::Cache" based API.
- •
- 'chi' indicates a "CHI" based API.
- •
- '1.0' indicates the custom cache API used in Mason 1.0x and earlier. This
compatibility layer is provided as a convenience for users upgrading from
older versions of Mason, but will not be supported indefinitely.
data_cache_defaults¶
- •
- Perl name: data_cache_defaults
- •
- Apache name: MasonDataCacheDefaults
- •
- Type in httpd.conf: hash_list
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Request"
A hash reference of default options to use for the "$m->cache"
command. For example, to use Cache::Cache's "MemoryCache"
implementation by default:
data_cache_defaults => {cache_class => 'MemoryCache'}
To use the CHI "FastMmap" driver by default:
data_cache_api => 'CHI',
data_cache_defaults => {driver => 'FastMmap'},
These settings are overridden by options given to particular
"$m->cache" calls.
data_dir¶
- •
- Perl name: data_dir
- •
- Apache name: MasonDataDir
- •
- Type in httpd.conf: string
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Interp"
The data directory is a writable directory that Mason uses for various features
and optimizations: for example, component object files and data cache files.
Mason will create the directory on startup, if necessary, and set its
permissions according to the web server User/Group.
Under Apache, data_dir defaults to a directory called "mason" under
the Apache server root. You will need to change this on certain systems that
assign a high-level server root such as
/usr!
In non-Apache environments, data_dir has no default. If it is left unspecified,
Mason will not use object files, and the default data cache class will be
"MemoryCache" instead of "FileCache".
decline_dirs¶
- •
- Perl name: decline_dirs
- •
- Apache name: MasonDeclineDirs
- •
- Type in httpd.conf: boolean
- •
- Default: 1
- •
- Belongs to: "HTML::Mason::ApacheHandler"
True or false, default is true. Indicates whether Mason should decline directory
requests, leaving Apache to serve up a directory index or a
"FORBIDDEN" error as appropriate. See the allowing directory
requests section of the administrator's manual for more information about
handling directories with Mason.
default_escape_flags¶
- •
- Perl name: default_escape_flags
- •
- Apache name: MasonDefaultEscapeFlags
- •
- Type in httpd.conf: string
- •
- Default: []
- •
- Belongs to: "HTML::Mason::Compiler"
Escape flags to apply to all <% %> expressions by default. The current
valid flags are
h - escape for HTML ('<' => '<', etc.)
u - escape for URL (':' => '%3A', etc.)
The developer can override default escape flags on a per-expression basis; see
the escaping expressions section of the developer's manual.
If you want to set
multiple flags as the default, this should be given as
a reference to an array of flags.
define_args_hash¶
- •
- Perl name: define_args_hash
- •
- Apache name: MasonDefineArgsHash
- •
- Type in httpd.conf: string
- •
- Default: auto
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
One of "always", "auto", or "never". This
determines whether or not an %ARGS hash is created in components. If it is set
to "always", one is always defined. If set to "never", it
is never defined.
The default, "auto", will cause the hash to be defined only if some
part of the component contains the string "ARGS". This is somewhat
crude, and may result in some false positives, but this is preferable to false
negatives.
Not defining the args hash means that we can avoid copying component arguments,
which can save memory and slightly improve execution speed.
dhandler_name¶
- •
- Perl name: dhandler_name
- •
- Apache name: MasonDhandlerName
- •
- Type in httpd.conf: string
- •
- Default: dhandler
- •
- Belongs to: "HTML::Mason::Request"
File name used for dhandlers. Default is "dhandler". If this is set to
an empty string ("") then dhandlers are turned off entirely.
dynamic_comp_root¶
- •
- Perl name: dynamic_comp_root
- •
- Apache name: MasonDynamicCompRoot
- •
- Type in httpd.conf: boolean
- •
- Default: 0
- •
- Belongs to: "HTML::Mason::Interp"
True or false, defaults to false. Indicates whether the comp_root can be
modified on this interpreter between requests. Mason can perform a few
optimizations with a fixed component root, so you should only set this to true
if you actually need it.
enable_autoflush¶
- •
- Perl name: enable_autoflush
- •
- Apache name: MasonEnableAutoflush
- •
- Type in httpd.conf: boolean
- •
- Default: 1
- •
- Belongs to: "HTML::Mason::Compiler"
True or false, default is true. Indicates whether components are compiled with
support for autoflush. The component can be compiled to a more efficient form
if it does not have to check for autoflush mode, so you should set this to 0
if you can.
- •
- Perl name: error_format
- •
- Apache name: MasonErrorFormat
- •
- Type in httpd.conf: string
- •
- Default: Varies
- •
- Belongs to: "HTML::Mason::Request"
Indicates how errors are formatted. The built-in choices are
- •
- brief - just the error message with no trace information
- •
- text - a multi-line text format
- •
- line - a single-line text format, with different pieces of
information separated by tabs (useful for log files)
- •
- html - a fancy html format
The default format under Apache and CGI is either
line or
html
depending on whether the error mode is
fatal or
output,
respectively. The default for standalone mode is
text.
The formats correspond to "HTML::Mason::Exception" methods named as_
format. You can define your own format by creating an appropriately
named method; for example, to define an "xml" format, create a
method "HTML::Mason::Exception::as_xml" patterned after one of the
built-in methods.
error_mode¶
- •
- Perl name: error_mode
- •
- Apache name: MasonErrorMode
- •
- Type in httpd.conf: string
- •
- Default: Varies
- •
- Belongs to: "HTML::Mason::Request"
Indicates how errors are returned to the caller. The choices are
fatal,
meaning die with the error, and
output, meaning output the error just
like regular output.
The default under Apache and CGI is
output, causing the error to be
displayed in the browser. The default for standalone mode is
fatal.
escape_flags¶
- •
- Perl name: escape_flags
- •
- Apache name: MasonEscapeFlags
- •
- Type in httpd.conf: hash_list
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Interp"
A hash reference of escape flags to set for this object. See the section on the
set_escape method for more details.
ignore_warnings_expr¶
- •
- Perl name: ignore_warnings_expr
- •
- Apache name: MasonIgnoreWarningsExpr
- •
- Type in httpd.conf: regex
- •
- Default: qr/Subroutine .* redefined/i
- •
- Belongs to: "HTML::Mason::Interp"
Regular expression indicating which warnings to ignore when loading components.
Any warning that is not ignored will prevent the component from being loaded
and executed. For example:
ignore_warnings_expr =>
'Global symbol.*requires explicit package'
If set to undef, all warnings are heeded. If set to '.', warnings are turned off
completely as a specially optimized case.
By default, this is set to 'Subroutine .* redefined'. This allows you to declare
global subroutines inside <%once> sections and not receive an error when
the component is reloaded.
in_package¶
- •
- Perl name: in_package
- •
- Apache name: MasonInPackage
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Commands
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
This is the package in which a component's code is executed. For historical
reasons, this defaults to "HTML::Mason::Commands".
interp_class¶
- •
- Perl name: interp_class
- •
- Apache name: MasonInterpClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Interp
- •
- Belongs to: "HTML::Mason::ApacheHandler"
The class to use when creating a interpreter. Defaults to HTML::Mason::Interp.
lexer_class¶
- •
- Perl name: lexer_class
- •
- Apache name: MasonLexerClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Lexer
- •
- Belongs to: "HTML::Mason::Compiler"
The class to use when creating a lexer. Defaults to HTML::Mason::Lexer.
max_recurse¶
- •
- Perl name: max_recurse
- •
- Apache name: MasonMaxRecurse
- •
- Type in httpd.conf: string
- •
- Default: 32
- •
- Belongs to: "HTML::Mason::Request"
The maximum recursion depth for the component stack, for the request stack, and
for the inheritance stack. An error is signalled if the maximum is exceeded.
Default is 32.
named_component_subs¶
- •
- Perl name: named_component_subs
- •
- Apache name: MasonNamedComponentSubs
- •
- Type in httpd.conf: boolean
- •
- Default: 0
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
When compiling a component, use uniquely named subroutines for the a component's
body, subcomponents, and methods. Doing this allows you to effectively profile
Mason components. Without this, all components simply show up as __ANON__ or
something similar in the profiler.
object_file_extension¶
- •
- Perl name: object_file_extension
- •
- Apache name: MasonObjectFileExtension
- •
- Type in httpd.conf: string
- •
- Default: .obj
- •
- Belongs to: "HTML::Mason::Interp"
Extension to add to the end of object files. Default is ".obj".
out_method¶
- •
- Perl name: out_method
- •
- Apache name: MasonOutMethod
- •
- Type in httpd.conf: code
- •
- Default: Print to STDOUT
- •
- Belongs to: "HTML::Mason::Request"
Indicates where to send output. If out_method is a reference to a scalar, output
is appended to the scalar. If out_method is a reference to a subroutine, the
subroutine is called with each output string. For example, to send output to a
file called "mason.out":
my $fh = new IO::File ">mason.out";
...
out_method => sub { $fh->print($_[0]) }
By default, out_method prints to standard output. Under Apache, standard output
is redirected to "$r->print".
plugins¶
- •
- Perl name: plugins
- •
- Apache name: MasonPlugins
- •
- Type in httpd.conf: list
- •
- Default: []
- •
- Belongs to: "HTML::Mason::Request"
An array of plugins that will be called at various stages of request processing.
Please see HTML::Mason::Plugin for details.
postamble¶
- •
- Perl name: postamble
- •
- Apache name: MasonPostamble
- •
- Type in httpd.conf: string
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
Text given for this parameter is placed at the end of each component. See also
preamble. The request will be available as $m in postamble code.
postprocess_perl¶
- •
- Perl name: postprocess_perl
- •
- Apache name: MasonPostprocessPerl
- •
- Type in httpd.conf: code
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Compiler"
Sub reference that is called to postprocess the Perl portion of a compiled
component, just before it is assembled into its final subroutine form. The sub
is called with a single parameter, a scalar reference to the Perl portion of
the component. The sub is expected to process the string in-place. See also
preprocess and postprocess_text.
postprocess_text¶
- •
- Perl name: postprocess_text
- •
- Apache name: MasonPostprocessText
- •
- Type in httpd.conf: code
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Compiler"
Sub reference that is called to postprocess the text portion of a compiled
component, just before it is assembled into its final subroutine form. The sub
is called with a single parameter, a scalar reference to the text portion of
the component. The sub is expected to process the string in-place. See also
preprocess and postprocess_perl.
preamble¶
- •
- Perl name: preamble
- •
- Apache name: MasonPreamble
- •
- Type in httpd.conf: string
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
Text given for this parameter is placed at the beginning of each component, but
after the execution of any "<%once>" block. See also
postamble. The request will be available as $m in preamble code.
preloads¶
- •
- Perl name: preloads
- •
- Apache name: MasonPreloads
- •
- Type in httpd.conf: list
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Interp"
A list of component paths, optionally with glob wildcards, to load when the
interpreter initializes. e.g.
preloads => ['/foo/index.html','/bar/*.pl']
Default is the empty list. For maximum performance, this should only be used for
components that are frequently viewed and rarely updated. See the preloading
components section of the administrator's manual for further details.
As mentioned in the developer's manual, a component's "<%once>"
section is executed when it is loaded. For preloaded components, this means
that this section will be executed before a Mason or Apache request exist, so
preloading a component that uses $m or $r in a "<%once>"
section will fail.
preprocess¶
- •
- Perl name: preprocess
- •
- Apache name: MasonPreprocess
- •
- Type in httpd.conf: code
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Compiler"
Sub reference that is called to preprocess each component before the compiler
does it's magic. The sub is called with a single parameter, a scalar reference
to the script. The sub is expected to process the script in-place. This is one
way to extend the HTML::Mason syntax with new tags, etc., although a much more
flexible way is to subclass the Lexer or Compiler class. See also
postprocess_text and postprocess_perl.
request_class¶
- •
- Perl name: request_class
- •
- Apache name: MasonRequestClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Request
- •
- Belongs to: "HTML::Mason::Interp"
The class to use when creating requests. Defaults to HTML::Mason::Request.
resolver_class¶
- •
- Perl name: resolver_class
- •
- Apache name: MasonResolverClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Resolver::File
- •
- Belongs to: "HTML::Mason::Interp"
The class to use when creating a resolver. Defaults to
HTML::Mason::Resolver::File.
static_source¶
- •
- Perl name: static_source
- •
- Apache name: MasonStaticSource
- •
- Type in httpd.conf: boolean
- •
- Default: 0
- •
- Belongs to: "HTML::Mason::Interp"
True or false, default is false. When false, Mason checks the timestamp of the
component source file each time the component is used to see if it has
changed. This provides the instant feedback for source changes that is
expected for development. However it does entail a file stat for each
component executed.
When true, Mason assumes that the component source tree is unchanging: it will
not check component source files to determine if the memory cache or object
file has expired. This can save many file stats per request. However, in order
to get Mason to recognize a component source change, you must flush the memory
cache and remove object files. See static_source_touch_file for one easy way
to arrange this.
We recommend turning this mode on in your production sites if possible, if
performance is of any concern.
static_source_touch_file¶
- •
- Perl name: static_source_touch_file
- •
- Apache name: MasonStaticSourceTouchFile
- •
- Type in httpd.conf: string
- •
- Default: None
- •
- Belongs to: "HTML::Mason::Interp"
Specifies a filename that Mason will check once at the beginning of of every
request. When the file timestamp changes, Mason will (1) clear its in-memory
component cache, and (2) remove object files if they have not already been
deleted by another process.
This provides a convenient way to implement static_source mode. All you need to
do is make sure that a single file gets touched whenever components change.
For Mason's part, checking a single file at the beginning of a request is much
cheaper than checking every component file when static_source=0.
subcomp_class¶
- •
- Perl name: subcomp_class
- •
- Apache name: MasonSubcompClass
- •
- Type in httpd.conf: string
- •
- Default: HTML::Mason::Component::Subcomponent
- •
- Belongs to: "HTML::Mason::Compiler::ToObject"
The class into which subcomponent objects are blessed. This defaults to
HTML::Mason::Component::Subcomponent.
use_object_files¶
- •
- Perl name: use_object_files
- •
- Apache name: MasonUseObjectFiles
- •
- Type in httpd.conf: boolean
- •
- Default: 1
- •
- Belongs to: "HTML::Mason::Interp"
True or false, default is true. Specifies whether Mason creates object files to
save the results of component parsing. You may want to turn off object files
for disk space reasons, but otherwise this should be left alone.

- Belongs to: "HTML::Mason::Compiler"
True or false, default is true. Indicates whether component line numbers that
appear in error messages, stack traces, etc. are in terms of the source file

helpful, object file line numbers may be more appropriate for in-depth
debugging sessions.
