How to Use the Command 'pandoc' (with Examples)
Pandoc serves as a universal document converter, allowing users to transform documents across a wide array of formats. It is particularly valuable for professionals who need to convert text from one markup format to another, such as Markdown to PDF or HTML. Pandoc’s ability to handle many different document types makes it a staple tool in the development and content creation industries.
Use Case 1: Convert a File to PDF
Code:
pandoc path/to/input.md -o|--output path/to/output.pdf
Motivation:
There are times when you need a document in a more universally accepted format, such as PDF, which is ideal for printing or sharing. Markdown formats are excellent for editing and writing but are not universally recognized or easy to share in their native format. Converting Markdown files to PDF ensures your content looks professional and is accessible to any user.
Explanation:
pandoc: Initiates the command-line tool that performs the conversion.path/to/input.md: Specifies the path to the source file in Markdown format.-o|--output: Tells Pandoc where to save the converted document and specifies the desired file format based on its extension (.pdf).path/to/output.pdf: Determines the output path and file type for the conversion.
Example Output:
A PDF file, named as specified (output.pdf), is generated in the directory you chose, displaying the original Markdown content with formatting maintained as closely as possible.
Use Case 2: Convert to a Standalone File with Appropriate Headers/Footers
Code:
pandoc path/to/input.md -s|--standalone -o|--output path/to/output.html
Motivation:
Regular conversion might not include necessary document structure like headers or footers, especially when aiming to produce self-contained documents like web pages. Generating standalone files with correct structure ensures professional presentation and usability, especially useful for those involved in documentation or web content creation.
Explanation:
pandoc: The tool for document transformation.path/to/input.md: The input document in Markdown format.-s|--standalone: Ensures that the output document functions independently, complete with syntax and layout components like headers or footers.-o|--output: Directs Pandoc on where and how to save the new file.path/to/output.html: The final output will be an HTML file with complete document structure.
Example Output:
The converted standalone HTML file will appear complete with necessary tags and structure, ready to be viewed in a web browser with the correct formatting.
Use Case 3: Manually Specify Format Detection and Conversion
Code:
pandoc -f|-r|--from|--read docx|... path/to/input -t|-w|--to|--write pdf|... -o|--output path/to/output
Motivation:
When dealing with non-standard file extensions or ambiguous file formats, automatic detection might not suffice. This use case allows users to manually specify input and output formats, ensuring precise control over the conversion process.
Explanation:
pandoc: The core tool to perform document conversion.-f|-r|--from|--read: Specifies the format of the input file, such as DOCX.docx|...: The chosen format of the input file being converted.path/to/input: The path to the original file.-t|-w|--to|--write: Declares the desired format for the output file, which in this example is PDF.pdf|...: Indicates the format for the result.-o|--output: Designates where the result is saved and in which format.path/to/output: Names both the path and type of the output document.
Example Output:
A PDF, or another specified file type, is produced named as you define, with conversion done considering the specified input and output formats—giving users greater flexibility and accuracy.
Use Case 4: List All Supported Input Formats
Code:
pandoc --list-input-formats
Motivation:
Understanding what file types a tool can process is vital for maximizing its utility. Before attempting a conversion, users often want to verify compatibility with their file format, ensuring efficiency and avoiding errors.
Explanation:
pandoc: Engages the document converter.--list-input-formats: Command to generate a list of all input formats Pandoc can handle, providing the user with a comprehensive overview.
Example Output:
A list of possible input formats will be displayed on the terminal, helping users make informed decisions about file compatibilities before proceeding with conversions.
Use Case 5: List All Supported Output Formats
Code:
pandoc --list-output-formats
Motivation:
Just as important as knowing which formats you can input, understanding the available output options lets you plan how best to convert your work. This is especially significant for ensuring that the end format meets your needs or the requirements of your audience.
Explanation:
pandoc: Launches the tool for processing document formats.--list-output-formats: Outputs a complete list of formats Pandoc can write to, providing clarity and aiding planning for potential conversions.
Example Output:
