It is a slightly modified version of Brian Kernighan's PIC language from 40 years ago, updated to make it safe to use on the web. Pikchr is ideal for use in Markdown - see the examples at https://pikchr.org/home/skn_default/doc/trunk/doc/examples.md , or the same examples in darkmode: https://pikchr.org/home/skn_ardoise/doc/trunk/doc/examples.md . Click on each diagram to see the plain text source code. Pikchr is implemented in a single C source file with no dependencies, intended for embedding within as many tools as possible. -- Dan Shearer dan-QNUrB6Xd9YFAfugRpC6u6w@public.gmane.org ^ permalink raw reply [flat|nested] 9+ messages in thread

Thanks, > No, Pikchr is not currently available as an executable. However pretty much any C build environment will create an executable as follows. 1. Get the (very small, zero dependency) Pikchr source from one of: a) https://pikchr.org/home/download . This is an automatic tarball/zip/sqlar from the latest Fossil checkin. b) the command "fossil clone https://pikchr.org/" 2. cd pikchr make this will give you a binary called "pikchr" (probably PIKCHR.EXE for Windows, but I have never tried with Windows) 3. You can then try pikchr: ./pikchr --svg-only examples/headings01.pikchr will produce only the SVG code corresponding to the Pikchr code. ./pikchr examples/headings01.pikchr > /tmp/headings.html This wraps the SVG in HTML, you can point your web browser at /tmp/headings.html I have an SVG convertor called rsvg-convert from the librsvg2-bin package.

The obvious place at least initially for such code blocks to appear is in Markdown. Pikchr is intended (just like PIC was) to be used as a plugin/filter in any context, but it's main development environment to date has been in the Fossil variant of Markdown, see https://www.fossil-scm.org/xfer/md_rules. Pandoc doesn't support Fossil Markdown, but it seems like it would not be hard to do so. -- Dan Shearer dan-QNUrB6Xd9YFAfugRpC6u6w@public.gmane.org -- You received this message because you are subscribed to the Google Groups "pandoc-discuss" group.

You can learn about how to write pandoc filters from the documentation https://pandoc.org/filters.html https://pandoc.org/lua-filters.html You could, in principle, write the whole filter in C (using the pikchr liibrary and a JSON-parsing and generating library).
