Formats

HTML

Pages to be included in the documentation

By default, Github Wiki to pdf Converter will check for the following files to use as a table of contents (TOC):

• _Toc.md
• _Sidebar.md (which is the default sidebar file on Github wikis)

When finding a TOC, wiki2pdf will only generate pages linked from this TOC. Supported link formats are:

• Markdown links with local path [Call Log](Call-Log) / [Log](Call-Log.md) / [Calls](/Call-Log.md);
• Markdown links with remote (http/https) path [Calls](https://github.com/yourrepo/someproject/wiki/Call-Log). Only those links that are placed in TOC will be converted to local page ids;
• Github wiki links [[Call Log]] / [[Call-Log]] / [[Call Log|Call-Log]] / [[Log|Call Log]].

Inlining

By default, the HTML output format will generate a single-page HTML document of you wiki, with all assets inlined, such as images, css, and javascript. So all you need to transfer documentation (to a colleague for example) is to send him/her this unique file.

You can disable this inlining feature by passing --disable-inline-assets (or -d) such as several files will be generated for each of images, css and javascript files.

Table of contents (TOC)

The TOC is rendered using a fixed div in the HTML documentation. You can use --toc-level to prevent the TOC div to overlap the body element.

PDF

Page breaking

By default all TOC pages starts from a new page. Also with default css you will never see your code block or image broken in two pages. To add additional page breaking use style="page-break-before: always !important; with empty div element.

Code highlighting

Code highlighting is rendered using highlight.js. You can customize the theme used by using the --highlight-theme option. By default, github theme is used.

Footers and Headers (pdf rendering with node-html-pdf)

wiki2pdf --footer option be used to read the header or footer either out of the footer and header config object or out of the html source. You can either set a default header & footer or overwrite that by appending a page number (1 based index) to the id="pageHeader" attribute of a html tag.

You can use any combination of those tags. The library tries to find any element, that contains the pageHeader or pageFooter id prefix.

<div id="pageHeader">Default header</div>
<div id="pageHeader-first">Header on first page</div>
<div id="pageHeader-2">Header on second page</div>
<div id="pageHeader-3">Header on third page</div>
<div id="pageHeader-last">Header on last page</div>
...
<div id="pageFooter">Default footer</div>
<div id="pageFooter-first">Footer on first page</div>
<div id="pageFooter-2">Footer on second page</div>
<div id="pageFooter-last">Footer on last page</div>
