Markdown processing tools, including mdmerge
Project description
MarkdownTools2
MarkdownTools is a collection of command line utilities for processing Markdown text files. At the moment the collection includes only one utility: mdmerge. Over time additional utilities will be added to support Markdown workflows.
Note: if you are using Python 3, then you need the MarkdownTools package.
mdmerge
mdmerge is a command line utility that produces a single Markdown document by merging a set of Markdown documents. The merge can be accomplished by expanding include declarations found in the input files, by concatenating a list of files found in an index file, or both.
Wait, doesn’t Marked 2 already do that?
Brett Terpstra’s Marked 2 application is a GUI product that runs on OS X; it watches Markdown text and displays the formatted output; it has extensive support for multi-file Markdown documents. Marked is my tool of choice for viewing formatted Markdown. I use it whenever I’m creating or reviewing Markdown content on my OS X machine. The invaluable multi-file document support in Marked is what drove me to create mdmerge.
mdmerge brings multi-file Markdown document processing to the command line. It is useful in any automated scripting environment where Markdown is processed. For example, I use it in automated build scripts (e.g., using gmake or Grunt) to produce documentation for the software I’m building. It is cross-platform; you can pre-process the Markdown files on any common OS that has a recent version of Python.
What kinds of Markdown does it work with?
mdmerge has been tested with documents containing these Markdown syntax variants:
classic (John Gruber’s Markdown syntax)
MultiMarkdown (Fletcher Penny’s syntax, MultiMarkdown version 4)
GHF (GitHub Flavored Markdown)
How do files get included?
mdmerge accepts include declarations in these styles:
MultiMarkdown transclusions
LeanPub index files (also known as book files)
Includes can be nested; that is, a file can include another file that itself include other files, and so on. Index (or book) files are only processed as such when they are the primary input; they cannot be nested – files listed in the index file are treated as normal input files (including expanding include specifications found within).
Command Line Syntax
The command line looks like this:
mdmerge [options] [-o outputfile] inputfiles mdmerge [options] [-o outputfile] -
Options
- options
One or more of –book, –export-target, –ignore-transclusions, –just-raw, –leanpub, –version, –help, -h.
- --book
Treat STDIN as an index file (a “book” file).
- --export-target [html|latex|lyx|opml|rtf|odf]
Indicates the ultimate output target of the markdown processor, but primarily impacts wildcard substitution in Marked inclusion.
- --help
Help information
- -h
Help information
- --ignore-transclusions
Leave any MultiMarkdown transclusion specifications alone; do not include the specified file. Useful if you want to mix Marked/LeanPub includes and MultiMarkdown includes, but have MultiMarkdown handline the transclusions.
- --just-raw
Ignore all include specifications except for raw includes; useful for processing the output of the Markdown processor to pick up the raw file include specifications that should have passed through untouched.
- --leanpub
Indicates that any input file named book.txt should be treated as a LeanPub index file.
- --version
Gives the version information about the utility.
- -o outputfile
The filepath in which to store the merged text. If not specified, then STDOUT is used.
- --outfile outputfile
same as -o.
- inputfiles
A list of space separated input files that can be merged together. If multiple files are given, they are treated as if they were specified in a LeanPub index file.
- -
The input comes from STDIN.
Installation
Note: Requires Python 2.6 or later. For Python 3 environments use the MarkdownTools package.
Install with:
pip install MarkdownTools2
This will create the command mdmerge. Use mdmerge --version and mdmerge --help to confirm the installation.
