runmd 0.15.1

A CLI tool to run or list code blocks from Markdown files.

A CLI Tool for Executing Code Blocks in Markdown Files.

RunMD is a command-line tool designed to extract and execute code blocks from Markdown files. It's particularly useful for managing and running code snippets embedded in documentation or notes.

⚠ RunMD is intended for use with scripting languages only (e.g., Shell, Python, Ruby, JavaScript). It does not support compiled languages (e.g., C, C++, Java) as it cannot handle compilation and execution steps.

⚠ RunMD is different from interactive notebooks like Jupyter or Zepplin. Each code block is independent and executed separately.

To add an executable code block to your Markdown file, use the following syntax:

# My executable code block
    ```sh {name=export-echo,tag=example}
    EXPORT MYSTR="a simple export and echo"
    echo $MYSTR
    ```

List Code Blocks

To list all code block names in Markdown files within the current directory:

runmd list

Show a Specific Code Block

To display the content of a specific code block:

runmd show <code-block-name>

Run a Specific Code Block

To execute a specific code block by name:

runmd run <code-block-name>

Run all code blocks with a given tag

To execute a specific code block by name:

runmd run -t <tag>

Run all code blocks

To execute a specific code block by name:

runmd run all

Run a Specific Code Block with nvironment variable

To execute a specific code block by name:

runmd run <code-block-name> --env <KEY1>=<VALUE1> <KEY2=VALUE2>

Run all code blocks

To execute all code blocks in Markdown files within the current directory:

Configuration

You can customize how different scripting languages are executed by creating a configuration file at ~/.config/runmd/config.json. Here’s an example configuration:

{
    "sh": {
        "command": "bash",
        "options": ["-c"]
    },
    "python": {
        "command": "python",
        "options": []
    },
    "ruby": {
        "command": "ruby",
        "options": []
    }
}

Troubleshooting

• No Output: Ensure the Markdown code blocks are correctly formatted and the specified commands are valid for the environment.
• Permission Denied: Check if you have the required permissions to execute the commands in the code blocks.
