Small script to create Blogofile posts

2012-08-04 | Permalink

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.

#!/usr/bin/python3

# Simple helper tool to create blog entries.

import datetime
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

    def get_filename(self):
        filename = '%03d - %s.markdown' % (self.number, self.title)
        return os.path.join(self.path, filename)

    def create_file(self):
        with open(self.get_filename(), 'w') as out_f:
            out_f.write('---\n')
            out_f.write('title: ' + self.title + '\n')
            out_f.write('date: ' + self.date_str + '\n')
            out_f.write('categories: \n')
            out_f.write('---\n')
            out_f.write('\n')

number = find_next_number(BLOG_ENTRY_PATH)
title = prompt_for_title()
date = get_new_date()
post = Post(BLOG_ENTRY_PATH, number, title, date)
print(post.get_filename())
post.create_file()
os.system('%s "%s"&' % (EDITOR, post.get_filename()))
