Dist::Zilla::Plugin::TemplateCJM - Process templates, including version numbers & changes
This document describes version 4.20 of Dist::Zilla::Plugin::TemplateCJM, released August 17, 2013.
In your dist.ini:
[TemplateCJM] changelog = Changes ; this is the default changes = 1 ; this is the default file = README ; this is the default report_versions = 1 ; this is the default date_format = ; this is the default
This plugin is the successor to Module::Build::DistVersion. It performs the following actions:
fileattribute. Any number of templates may be present.
Each template may use the following variables:
The changes in the current release. This is a string containing all lines in Changes following the version/release date line up to (but not including) the next line that begins with a non-whitespace character (or end-of-file). The string does not end with a newline (since version 0.08).
You can include the changes from more than one release by setting the "changes" in
changes attribute. This is useful when you make a major release immediately followed by a bugfix release.
The release date taken from Changes and reformatted using "date_format". If
date_format is the empty string, or if the release date cannot be parsed as a date, this is the date exactly as it appears in Changes.
The release date taken from Changes as a DateTime object, or
undef if the release date could not be parsed as a date.
The name of the distribution.
The hash of metadata that will be stored in META.yml.
The TemplateCJM object that is processing the template.
The distribution's version number. (Also available as
The Dist::Zilla object that is creating the distribution.
Each section may use the same variables as step 2, plus the following:
The name of the module being processed (i.e., its package). In the case of a pure-POD file without a
package declaration, this is derived from its filename (which must match the regex
A Module::Metadata object containing information about the module. (Note that the filename in
$pm_info will not be correct.)
The module's version number. This may be different than the distribution's version, which is available as
$dist_version. In the case of a pure-POD file without a
$VERSION declaration, this will be the same as
It also peforms a BeforeRelease check to ensure that the release date in the changelog is a valid date. (I set the date to NOT until I'm ready to release.)
This is the name of the Changes file. It defaults to Changes.
This is the regex used to extract the version and release date from the Changes file. It defaults to
(\d[\d._]*)\s+(.+) (i.e. version number at beginning of the line, followed by whitespace, and everything after that is the release date). It it automatically anchored at the beginning of the line. Note: your version lines must not begin with whitespace. All other lines must begin with whitespace.
This is the number of releases to include in the
$changes variable passed to templates. It defaults to 1 (meaning only changes in the current release). This is useful when you make a major release immediately followed by a bugfix release.
This is the DateTime CLDR format to use for the
$date variable in templates. The default value is the empty string, which means to use the date exactly as it appeared in the Changes file.
This is the name of a file to process with Text::Template in step 2. The
file attribute may be listed any number of times. If you don't list any
files, it defaults to README. If you do specify any
files, then README is not processed unless explicitly specified.
This FileFinder provides the list of files that are processed in step 3. The default is
finder attribute may be listed any number of times.
If true (the default), report the version of each module processed.
$t->build_instructions( [$prefix] )
A template can use this method to add build instructions for the distribution (normally used in README).
$prefix is prepended to each line, and defaults to a single TAB.
It returns either
perl Build.PL ./Build ./Build test ./Build install
perl Makefile.PL make make test make install
depending on whether your distribution includes a Build.PL. The string will NOT end with a newline.
It throws an error if neither Build.PL nor Makefile.PL is found.
A template can use this method to add a link to the documentation of a required module. It returns either
L<Foo::Bar> (VERSION or later)
depending on whether VERSION is non-zero. (It determines VERSION by checking
recommends in your prerequisites.)
A template can use this method to add a list of required modules. It returns a string like:
Package Minimum Version ---------------------- --------------- perl 5.8.0 List::Util Moose 0.90
perl is one of the dependencies, it is listed first. Also, its version (if >= 5.6.0) will be normalized into double-decimal form, even if the prerequisites list it as floating point.
All other dependencies are listed in ASCIIbetical order. The string will NOT end with a newline.
If there are no dependencies, the string
None. will be returned.
TemplateCJM requires Dist::Zilla (4.300009 or later) and Text::Template. I also recommend applying Template_strict.patch to Text::Template. This will add support for the STRICT option, which will help catch errors in your templates.
No bugs have been reported.
