.IX Title "Bigtop::Backend::Init::Std 3"
.TH Bigtop::Backend::Init::Std 3 "2008-01-18" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Bigtop::Backend::Init::Std \- Bigtop backend which works sort of like h2xs
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
If your bigtop file looks like this:
.PP
.Vb 7
\&    config {
\&        build_dir `/home/yourname`;
\&        app_dir   `appsubdir`;
\&        Init Std {}
\&    }
\&    app App::Name {
\&    }
.Ve
.PP
when you type
.PP
.Vb 1
\&    bigtop --create your.bigtop Init
.Ve
.PP
or
.PP
.Vb 1
\&    bigtop --create your.bigtop all
.Ve
.PP
this module will generate the build directory as
.PP
.Vb 1
\&    /home/yourname/appsubdir
.Ve
.PP
Then it will make subdirectories: t, lib, and docs.  Then it will make
files: Changes, \s-1MANIFEST\s0, \s-1MANIFEST\s0.SKIP, \s-1README\s0, and Build.PL. 
Finally, it will copy your.bigtop into the docs dir of under appsubdir.
.PP
As with any backend, you can include \f(CW\*(C`no_gen 1;\*(C'\fR in its config block:
.PP
.Vb 3
\&    config {
\&        Init Std { no_gen 1; }
\&    }
.Ve
.PP
Then, no files will be generated.  But, you can also exclude indiviual
files it would build.  Simply list the file name as a keyword and
give the value no_gen:
.PP
.Vb 6
\&    config {
\&        Init Std {
\&            MANIFEST no_gen;
\&            Changes  no_gen;
\&        }
\&    }
.Ve
.PP
If you are in create mode and your config does not include app_dir, one
will be formed from the app name, in the manner of h2xs.  So, in the above
example it would be
.PP
.Vb 1
\&    /home/yourname/App-Name
.Ve
.PP
Outside of create mode, the current directory is used for building, if
it looks like a plausible build directory (it has a Build.PL, etc).  In
that case, having a base_dir and/or app_dir in your config will result
in warning(s) that they are being ignored.
.SH "KEYWORDS"
.IX Header "KEYWORDS"
This module registers app level keywords: authors, contact_us,
copyright_holder, license_text, and the now deprecated email (which is a
synonymn for contact_us).  These are also regiersted by Bigtop::Control and
they have the same meaning there.
.PP
It actually pays no attention to the rest of the app section of the
bigtop input, except to build the default app_dir from the app_name.
.SH "METHODS"
.IX Header "METHODS"
.IP "backend_block_keywords" 4
.IX Item "backend_block_keywords"
Tells tentmaker that I understand these config section backend block keywords:
.Sp
.Vb 7
\&    no_gen
\&    Build_PL
\&    Changes
\&    README
\&    MANIFEST
\&    MANIFEST_SKIP
\&    template
.Ve
.IP "what_do_you_make" 4
.IX Item "what_do_you_make"
Tells tentmaker what this module makes.  Summary: roughly what h2xs makes.
.IP "gen_Init" 4
.IX Item "gen_Init"
Called by Bigtop::Parser to get me to do my thing.
.IP "output_cgi" 4
.IX Item "output_cgi"
What I call on the various \s-1AST\s0 packages to do my thing.
.IP "init_simple_file" 4
.IX Item "init_simple_file"
What I call to build each regular file (like Changes, Build.PL, etc.).
.IP "setup_template" 4
.IX Item "setup_template"
Called by Bigtop::Parser so the user can substitute an alternate template
for the hard coded one here.
