NAME

CPANPLUS::Internals::Source - internals for updating source files

SYNOPSIS

    ### lazy load author/module trees ###
    $cb->_author_tree;
    $cb->_module_tree;

DESCRIPTION

CPANPLUS::Internals::Source controls the updating of source files and the parsing of them into usable module/author trees to be used by CPANPLUS .

Functions exist to check if source files are still good to use as well as update them, and then parse them.

The flow looks like this:

    $cb->_author_tree || $cb->_module_tree
        $cb->_check_trees
            $cb->__check_uptodate
                $cb->_update_source
            $cb->__update_custom_module_sources
                $cb->__update_custom_module_source
        $cb->_build_trees
            ### engine methods
            {   $cb->_init_trees;
                $cb->_standard_trees_completed
                $cb->_custom_trees_completed
            }
            $cb->__create_author_tree
                ### engine methods
                { $cb->_add_author_object }
            $cb->__create_module_tree
                $cb->__create_dslip_tree
                ### engine methods
                { $cb->_add_module_object }
            $cb->__create_custom_module_entries
    $cb->_dslip_defs

METHODS

$cb->_build_trees( uptodate => BOOL, [use_stored => BOOL, path => $path, verbose => BOOL] )

This method rebuilds the author- and module-trees from source.

It takes the following arguments:

• uptodate

  Indicates whether any on disk caches are still ok to use.

• path

  The absolute path to the directory holding the source files.

• verbose

  A boolean flag indicating whether or not to be verbose.

• use_stored

  A boolean flag indicating whether or not it is ok to use previously stored trees. Defaults to true.

Returns a boolean indicating success.

$cb->_check_trees( [update_source => BOOL, path => PATH, verbose => BOOL] )

Retrieve source files and return a boolean indicating whether or not the source files are up to date.

Takes several arguments:

• update_source

  A flag to force re-fetching of the source files, even if they are still up to date.

• path

  The absolute path to the directory holding the source files.

• verbose

  A boolean flag indicating whether or not to be verbose.

Will get information from the config file by default.

$cb->__check_uptodate( file => $file, name => $name, [update_source => BOOL, verbose => BOOL] )

__check_uptodate checks if a given source file is still up-to-date and if not, or when update_source is true, will re-fetch the source file.

Takes the following arguments:

• file

  The source file to check.

• name

  The internal shortcut name for the source file (used for config lookups).

• update_source

  Flag to force updating of sourcefiles regardless.

• verbose

  Boolean to indicate whether to be verbose or not.

Returns a boolean value indicating whether the current files are up to date or not.

$cb->_update_source( name => $name, [path => $path, verbose => BOOL] )

This method does the actual fetching of source files.

It takes the following arguments:

• name

  The internal shortcut name for the source file (used for config lookups).

• path

  The full path where to write the files.

• verbose

  Boolean to indicate whether to be verbose or not.

Returns a boolean to indicate success.

$cb->__create_author_tree([path => $path, uptodate => BOOL, verbose => BOOL])

This method opens a source files and parses its contents into a searchable author-tree or restores a file-cached version of a previous parse, if the sources are uptodate and the file-cache exists.

It takes the following arguments:

• uptodate

  A flag indicating whether the file-cache is uptodate or not.

• path

  The absolute path to the directory holding the source files.

• verbose

  A boolean flag indicating whether or not to be verbose.

Will get information from the config file by default.

Returns a tree on success, false on failure.

$cb->_create_mod_tree([path => $path, uptodate => BOOL, verbose => BOOL])

This method opens a source files and parses its contents into a searchable module-tree or restores a file-cached version of a previous parse, if the sources are uptodate and the file-cache exists.

It takes the following arguments:

• uptodate

  A flag indicating whether the file-cache is up-to-date or not.

• path

  The absolute path to the directory holding the source files.

• verbose

  A boolean flag indicating whether or not to be verbose.

Will get information from the config file by default.

Returns a tree on success, false on failure.

$cb->__create_dslip_tree([path => $path, uptodate => BOOL, verbose => BOOL])

This method opens a source files and parses its contents into a searchable dslip-tree or restores a file-cached version of a previous parse, if the sources are uptodate and the file-cache exists.

It takes the following arguments:

• uptodate

  A flag indicating whether the file-cache is uptodate or not.

• path

  The absolute path to the directory holding the source files.

• verbose

  A boolean flag indicating whether or not to be verbose.

Will get information from the config file by default.

Returns a tree on success, false on failure.

$cb->_dslip_defs ()

This function returns the definition structure (ARRAYREF) of the dslip tree.

$file = $cb->_add_custom_module_source( uri => URI, [verbose => BOOL] );

Adds a custom source index and updates it based on the provided URI.

Returns the full path to the index file on success or false on failure.

$index = $cb->__custom_module_source_index_file( uri => $uri );

Returns the full path to the encoded index file for $uri , as used by all custom module source routines.

$file = $cb->_remove_custom_module_source( uri => URI, [verbose => BOOL] );

Removes a custom index file based on the URI provided.

Returns the full path to the index file on success or false on failure.

%files = $cb->__list_custom_module_sources

This method scans the 'custom-sources' directory in your base directory for additional sources to include in your module tree.

Returns a list of key value pairs as follows:

  /full/path/to/source/file%3Fencoded => http://decoded/mirror/path

$bool = $cb->__update_custom_module_sources( [verbose => BOOL] );

Attempts to update all the index files to your custom module sources.

If the index is missing, and it's a file:// uri, it will generate a new local index for you.

Return true on success, false on failure.

$ok = $cb->__update_custom_module_source

Attempts to update all the index files to your custom module sources.

If the index is missing, and it's a file:// uri, it will generate a new local index for you.

Return true on success, false on failure.

$bool = $cb->__write_custom_module_index( path => /path/to/packages, [to => /path/to/index/file, verbose => BOOL] )

Scans the path you provided for packages and writes an index with all the available packages to $path/packages.txt . If you'd like the index to be written to a different file, provide the to argument.

Returns true on success and false on failure.

$bool = $cb->__create_custom_module_entries( [verbose => BOOL] )

Creates entries in the module tree based upon the files as returned by __list_custom_module_sources .

Returns true on success, false on failure.
