I've written a very small Python 3 script to initialize Blogofile posts;

It generates a post number, prompts for a title, automatically sets the date, and adds an empty categories field.

It uses the basic simple-blog conventions, but the script should be easy enough to change to your setup.

Not very useful (yet?), but it makes starting a post just that tiny bit easier.

import os
import re

EDITOR='<editor here>' # I use 'geany -l7'
BLOG_ENTRY_PATH='<(sub)directory of _posts here>'

def find_next_number(path):
    '''Reads the directory, and returns the first available post number'''
    all_post_numbers = []
    all_files = os.listdir(path)
    p = re.compile('^([0-9]+)\s+')
    for filename in all_files:
        match = p.match(filename)
        if match:
            all_post_numbers.append(int(match.group(1)))
    all_post_numbers.sort()
    return all_post_numbers[-1] + 1;

def prompt_for_title():
    return input('Post title: ')

def get_new_date():
    now = datetime.datetime.now()
    return now.strftime('%Y/%m/%d %H:%M:%S')

class Post:
    def __init__(self, path, number, title, date_str):
        self.path = path
        self.number = number
        self.title = title
        self.date_str = date_str
