Using Python-Markdown on the Command Line ========================================= While Python-Markdown is primarily a python library, a command line script is included as well. While there are many other command line implementations of Markdown, you may not have them installed, or you may prefer to use Python-Markdown's various extensions. Generally, you will want to have the Markdown library fully installed on your system (``setup.py install`` or ``easy_install markdown``) to run the command line script. Assuming the `python` executable is on your system path, just run the following: python -m markdown [options] [args] That will run the module as a script. Note that on older python versions (2.5 and 2.6), you may need to specify the appropriate module: python -m markdown.__main__ [options] [args] Use the `--help` option for available options: python -m markdown --help If you are using Python 2.4 or you don't want to have to call the python executable directly, follow the instructions below: Setup ----- Upon installation, the ``markdown_py`` script will have been copied to your Python "Scripts" directory. Different systems require different methods to ensure that any files in the Python "Scripts" directory are on your system path. * **Windows**: Assuming a default install of Python on Windows, your "Scripts" directory is most likely something like ``C:\\Python26\Scripts``. Verify the location of your "Scripts" directory and add it to you system path. Calling ``markdown_py`` from the command line will call the wrapper batch file ``markdown_py.bat`` in the "Scripts" directory created during install. * __*nix__ (Linux, OSX, BSD, Unix, etc.): As each *nix distribution is different and we can't possibly document all of them here, we'll provide a few helpful pointers: * Some systems will automatically install the script on your path. Try it and see if it works. Just run ``markdown_py`` from the command line. * Other systems may maintain a separate "Scripts" directory which you need to add to your path. Find it (check with your distribution) and either add it to your path or make a symbolic link to it from your path. * If you are sure ``markdown_py`` is on your path, but it still isn't being found, check the permissions of the file and make sure it is executable. As an alternative, you could just ``cd`` into the directory which contains the source distribution, and run it from there. However, remember that your markdown text files will not likely be in that directory, so it is much more convenient to have ``markdown_py`` on your path. __Note:__ Python-Markdown uses "markdown_py" as a script name because the Perl implementation has already taken the more obvious name "markdown". Additionally, the default Python configuration on some systems would cause a script named "markdown.py" to fail by importing itself rather than the markdown library. Therefore, the script has been named "markdown_py" as a compromise. If you prefer a different name for the script on your system, it is suggested that you create a symbolic link to `markdown_py` with your preferred name. Usage ----- To use ``markdown_py`` from the command line, run it as $ markdown_py input_file.txt or $ markdown_py input_file.txt > output_file.html For a complete list of options, run $ markdown_py --help Using Extensions ---------------- For an extension to be run from the command line it must be provided in a module which should be in your python path (see [[writing_extensions]] for details). It can then be invoked by the name of that module: $ markdown -x footnotes text_with_footnotes.txt > output.html If the extension supports config options, you can pass them in as well: $ markdown -x "footnotes(PLACE_MARKER=~~~~~~~~)" input.txt
