NAME

PFT::Content - Filesytem tree mapping content

SYNOPSIS

PFT::Content->new($basedir);
PFT::Content->new($basedir, {create => 1});

DESCRIPTION

The structure is the following:

content
├── attachments
├── blog
├── pages
├── pics
└── tags

Properties

Quick accessors for directories

$tree->dir_root
$tree->dir_blog
$tree->dir_pages
$tree->dir_tags
$tree->dir_pics
$tree->dir_attachments

Non-existing directories are created by the constructor if the {create => 1} option is passed as last constructor argument.

Methods

new_entry

Create and return a page. A header is required as argument.

If the page does not exist it gets created according to the header. If the header contains a date, the page is considered to be a blog entry (and positioned as such). If the data is missing the day information, the entry is a month entry.

entry

Similar to new_entry, but does not create a content file if it doesn't exist already.

hdr_to_path

Given a PFT::Header object, returns the path of a page or blog page within the tree.

Note: this function does not work properly if you are seeking for a tag. Tags are a different beast, since they have the same header as a page, but they belong to a different place.

new_tag

Create and return a tag page. A header is required as argument. If the tag page does not exist it gets created according to the header.

tag

Similar to new_tag, but does not create the content file if it doesn't exist already.

blog_ls

List all blog entries (days and months).

pages_ls

List all pages (not tags pages)

tags_ls

List all tag pages (not regular pages)

entry_ls

List all entries (pages + blog + tags)

pic

Get a picture.

Accepts a list of strings which will be joined into the path of a picture file. Returns a PFT::Content::Blob instance, which could correspond to a non-existing file. The caller might create it (e.g. by copying a picture on the corresponding path).

pics_ls

List all pictures.

attachment

Get an attachment.

Accepts a list of strings which will be joined into the path of an attachment file. Returns a PFT::Content::Blob instance, which could correspond to a non-existing file. The caller might create it (e.g. by copying a file on the corresponding path).

Note that the input path should be made by strings in encoded form, in order to match the filesystem path.

attachments_ls

List all attachments.

blog_back

Go back in blog history of a number of days, return the entries corresponding to that date.

Expects one optional argument as the number of backward days in the blog history. If such argument is not provided, it defaults to 0, returning the entries of the latest edit day.

Please note that only days containing entries really count. If a blog had one entry today, no entry for yesterday and one the day before yesterday, blog_back(0) will return today's entry, and blog_back(1) will return the entry of two days ago.

Returns a list PFT::Content::Blog object, possibly empty if the blog does not have that many days.

blog_at

Go back in blog history to a certain date.

Expects as argument a PFT::Date item indicating a date to seek for blog entries.

Returns a possibly empty list of PFT::Content::Blog objects corresponding to the zero, one or more entries in the specified date.

detect_date

Given a PFT::Content::File object (or any subclass) determines the corresponding date by analyzing the path. Returns a PFT::Date object or undef if the page does not have date.

This function is helpful for checking inconsistency between the date declared in headers and the date used on the file system.

detect_slug

Given a PFT::Content::File object (or any subclass) determines the corresponding slug by analyzing the path. Returns the slug or undef if the content does not have a slug (e.g. months).

This function is helpful for checking inconsistency between the slug declared in headers and the slug used on the file system.

was_renamed

Notify this content abstraction about the renaming of the corresponding content file. First parameter is the original name, second parameter is the new name.
