Markdown_MakeLocal

Analyze a Markdown file for Image URLs, download these files and generate a new markdown with the downloaded files.

Has only been tested on OSX!

Usage

call the script with markdown file as parameter and optionally a folder (-m) where to save the Media will keep only images that are downloaded and generates a new markdown file with replaced links

python3 mdMakelocal.py file.md [file2.md ..] [-m Folder]

Requirements

• python3

with the libraries

• requests
• glob
• uuid
• hashlib
• markdown
• mimetypes
• threading
• lxml
• urllib

Things Considered in Development

• If the filename already exists in the media folder, it will append the files md5 hash to the filename
• The original markdown file will no be modified, only a new one generated with the appendix '-localMedia-X' where X is a number increased when a file already exists with that name.
• Downloads are threaded
• Image Filename and extension is generated from (in the following order)
  • html header 'content-disposition'
  • filename and html header 'content-type'
  • filename itself

Known Problems / Kwirks

• All links are downloaded, only afterwards the mimetype is detected. Then the file will be deleted if it's not matching a image type.
• the generated filename could be to long for the filesystem.
• Markdown file is converted to html to check for links, maybe would be nicer with regex?
