simplermarkdown 0.0.6 (2023-03-24)

New function 'output_shell' that can be used to include and run non-R code blocks such as bash and python using 'system2'. Code and output can be included in the resulting document.
Added 'eval' argument to 'output_eval' (the default output filter). When FALSE the code in the block is not run.
For 'output_eval' additional arguments in the markdown header of the code block (between the '{}') are passed on to the output block.
Warnings and messages can now also be captured in the output. Messages are captures by default. For warnings the option 'capture_warnings' has to be set to 'TRUE'.

When run from a non-interactive session the code is no longer reformatted.
Empty code blocks are now by default omitted in the output.
The 'raw_attribute' pandoc extension present in more recent versions of pandoc interfered with the procesessing of raw markdown blocks. This extension is now disabled.

'md_figure' and 'output_figure' can now echo the commands used to generate the figure. Use the arguments 'echo' and 'results' for that.
Errors with hopefully more informative error messages in case something goes wrong with the calls to pandoc.

Markdown documents without a header block would generate an error. Fixed.
Output was truncated for longer blocks of code. Fixed.
Expressions such as ‘iris[, foo := Sepal.Width/Sepal.Length]' were ’translated' to 'iris[, ':='(foo, Sepal.Width/Sepal.Length)]' in the output. Fixed.
When pandoc is not installed an empty dummy vignette is generated. This prevents warnings on the CRAN machines without pandoc. This should already have been working in the previous version except for a bug.
