Pandoc filter to allow file and header includes

pandoc-include

Pandoc filter to allow file and header includes.

The filter script is based on User Guide for Panflute. This repository is to provide a simple way to install and use it.

Features

• Recursive include (supported since v0.4.0): It depends on include-entry header to work
• Yaml header Merging (supported since v0.5.0): When an included file has its header, it will be merged into the current header. If there's a conflict, the original header of the current file remains.
• Header include (supported since v0.6.0): Use !include-header file.yaml to include Yaml header from file.

Installation

First, install python and python-pip.

Then, use pip to install:

pip install --user pandoc-include

After installation, make sure that the pandoc-include executable is put in the directory which is in the PATH environment.

Usage

Command

To use this filter, add to pandoc command

pandoc input.md --filter pandoc-include -o output.pdf

Header options

---
include-entry: 'path'
pandoc-options:
  - --filter=pandoc-include
  - <other options>
---

The pandoc-options option is a list to specify the pandoc options when recursively processing included files. By default, the included file will inherit the pandoc-options from its parent file, unless specified in its own file.

To make the recursive includes work, --filter=pandoc-include is necessary. The default value of pandoc-options is:

pandoc-options:
  - --filter=pandoc-include

The include-entry option is to make recursive includes work. The include-entry option is a path relative to current working directory or absolute where the entry file (the initial file) locates. It should be placed in the entry file only, not in the included files. It is optional and the default include-entry value is ..

For example, to compile a file in current directory, no header is needed:

pandoc test.md --filter pandoc-include -o test.pdf

However, to compile a file not in current directory, like:

pandoc dir/test.md --filter pandoc-include -o test.pdf

The header should now be set to: include-entry: 'dir'.

Syntax

Each include statement has its own line and has the syntax:

!include somefolder/somefile

!include-header file.yaml

Or

$include somefolder/somefile

$include-header file.yaml

Each include statement must be in its own paragraph. That is, in its own line and separated by blank lines.

The path can be either absolute or relative to the current file's directory. (If the include statement is in an included file, then the path is relative to the included file itself.) If no extension was given, ".md" is assumed.

The second syntax may lead to wrong highlighting when using a markdown editor. If it happens, use the first syntax.

Examples

File include

File include can be used to separate chapters into different files, or include some latex files:

---
title: Article
author: Author
toc: true
---

!include chapters/chap01.md

!include chapters/chap02.md

!include chapters/chap03.md

!include data/table.tex

Recursive include is supported from v0.4.0.

Header include

For header include, it is useful to define a header template and include it in many files.

For example, in the header.yaml, we can define basic info:

name: xxx
school: yyy
email: zzz

In the main.md, we can extend the header:

---
title: Title
---

!include-header header.yaml

# Section

Body

The main.md then is equivalent to the follow markdown:

---
title: Title
name: xxx
school: yyy
email: zzz
---

# Section

Body
