- Cheat Sheet. Introduction This document presents a technique for using a Markdown syntax variant, called Pandoc, and a bit of XML as a source format for documents that are Internet-Drafts (I-Ds) or RFCs. The goal of this technique is to let an author of an I-D focus on the main body of text without.
- In Pandoc you can also define a style for syntax highlighting, which is just perfect. Of course, the benefit of generating a Word file in between your Markdown and the final PDF is flexibility. I used this flexibility to for example add a sleek-looking title page, generate a (proper) table of contents, add page numbers, and more.
- Pandoc is a document converter. It can convert from a number of different markup formats to many other formats, such as.doc,.pdf etc. Pandoc is a command line tool with no GUI. It is an independent piece of software, separate from R. However, it comes bundled with R Studio because rmarkdown relies on it for document conversion.
17.3 Custom Pandoc templates
An R Markdown is first compiled to Markdown through knitr, and then converted to an output document (e.g., PDF, HTML, or Word) by Pandoc through a Pandoc template. While the default Pandoc templates used by R Markdown are designed to be flexible by allowing parameters to be specified in the YAML, users may wish to provide their own template for more control over the output format.
You can make use of additional YAML fields from the source document when designing a Pandoc template. For example, you may wish to have a department
field to be added to your title page, or include an editor
field to be displayed below the author. We can add additional variables to the Pandoc template by surrounding the variable in dollar signs ($
) within the template. Most variables take values from the YAML metadata of the R Markdown document (or command-line arguments passed to Pandoc). We may also use conditional statements and for-loops. Readers are recommended to check the Pandoc manual for more details: https://pandoc.org/MANUAL.html#using-variables-in-templates. Below is an example of a very minimal Pandoc template for HTML documents that only contains two variables ($title$
and $body$
):
Pandoc is an opensource utility to create documents from markdown. We can create PDF, Doc, doc, html and other formats. RPM Command Cheat Sheet; Creating a large.
For R Markdown to use the customized template, you can specify the template
option in the output format (provided that the output format supports this option), e.g.,
If you wish to design your own template, we recommend starting from the default Pandoc templates included within the rmarkdown package (https://github.com/rstudio/rmarkdown/tree/master/inst/rmd) or Pandoc’s built-in templates (https://github.com/jgm/pandoc-templates).
- USAGE
- Setting document-specific options
- EXTRAS
- EXAMPLE
- Extended example using post-processing options
pdoc - typeset pandoc documents with document-specific, default options
version 0.10.0
This is just a small executable and a hack to pandoc: you can use it to set document-specific, default options for pandoc in the typesetting process. Of course, you can safely ignore these settings and return to the standard way of doing things at all times.
Usage is absolutely straight-forward:
Usage on the commandline
If you want your file to be typeset using the document-specific default options, run
If you want standard processing of that file, simply run pandoc as usual:
Setting document-specific options
Setting options
Sprinkle <!--+ --pandoc-option1 --pandoc--option2 +-->
all over your pandoc file -- just as your would use them on the shell. pdoc
will read these and add them to the commandline that is passed to a standard pandoc typesetting.
Defining post-processing behavior
Pandoc Cheat Sheets
Use <!--& (some post processing action) &-->
as the special markup to pdoc
for post-processing options. These will be concatenated to the pandoc-commandline that is generated via &&
, just like so:
This is just a simple hack reading out specially marked comments in your pandoc source. Everything will stay usable as always. When typesetting in the standard manner, these comments are simply ignored.
See the executable for the details.
Shell variables
You can use shell variables as usual, e.g. $HOME
, etc.
Use policies
When doing more complicatd things (see example below) I like to use so-called pandoc-policies (as I call them).
I keep a folder ~/.pandoc/policies
next to ~/.pandoc/templates
containing files like ~/.pandoc/policies/columns.latex
(handling column-layouts) ~/.pandoc/policies/squeeze.latex
(for whitespace squeezing), and so on...
All of these policies are to be included by pandoc
's -H / --include-in-header=
-switch, so it makes:
Suppose you have a squeeze and a columns-policy in your policy-folder, your document might look like this:
Extended example using post-processing options
Here is a somewhat more complicated example: the cheat-sheet generator that I'm currently using while learning for my final examination:
This cheat-sheet generator can simply be called using pdoc cheatsheet.pandoc
and will additionally use pdfjam to squeeze even more of the resulting pdf pages together. On a Mac, it will additionally open the file after the final pdfjam rendering for quality inspection ;-).
Things to note
Note how several policies are grouped together on shell level, using curly-bracket expansion:
Also note, how additional options are set via
pandoc
's-V
-switch, and how even more options are smuggled in intopandoc
's own latex template. (The latter you can find usingpandoc -D latex
) in using
