#########################################################################################
|
||||
#
|
||||
# This is a very basic blog system
|
||||
#
|
||||
# Basically it asks the user to create a text file, then converts it into a .html file
|
||||
# and then rebuilds the index.html and feed.rss.
|
||||
#
|
||||
# Comments are not supported.
|
||||
#
|
||||
# This script is standalone, it doesn't require any other file to run
|
||||
#
|
||||
# Files that this script generates:
|
||||
# - main.css (inherited from my web page) and blog.css (blog-specific stylesheet)
|
||||
# - one .html for each post
|
||||
# - index.html (regenerated each run)
|
||||
# - feed.rss (regenerated each run)
|
||||
# - all_posts.html (regenerated each run)
|
||||
# - it also generates temporal files, which are removed afterwards
|
||||
#
|
||||
# It generates valid html and rss files, so keep care to use valid xhtml when editing a post
|
||||
#
|
||||
# There are many loops which iterate on '*.html' so make sure that the only html files
|
||||
# on this folder are the blog entries and index.html and all_posts.html. Drafts must go
|
||||
# into drafts/ and any other *.html file should be moved out of the way
|
||||
#
|
||||
# TODO instead of using a file for $content, use a variable to avoid disk writes
|
||||
# TODO enclose all variables with quotes (thanks Durad)
|
||||
# TODO use a tag for dates, and keep them in sync with the html files (thanks Durad)
