If you want to help, please sumbit a Pull Request to my repository and I'd gladly merge it if it works. I could probably use some bounding box or better way to get only the equations, but I didn't.
You can have LaTeX “rendered” in a GitHub README file! The sizes of the text may be weird. If you run this command and don't push these png files, then nothing will show up. NB: The replacement looks for equations (noted by eq_noSOMETHING. If you have better solutions, please post in the comments.
Write out the parsed md file, which was named using new_md. Replace all the LaTeX with the insert_string, which is raw HTML now. The file will be something like eq_no_01.png in the same folder as the rmd argument. 
This is so that they will render in the README.

Convert the PDF to a PNG using animation::im.convert. This will crop out anything that's not the LaTeX equation you wanted. Run knitr::plot_crop on this document. argument can be a character vector of other packages to load in that document. Put this LaTeX into a simple LaTeX document with begin. #LATEXIT ONE RMD FILE CODE#
Find the equations using ($$ and $) parse them out, throwing out any code demarcated with backticks (”). So what is the function actually doing? Something convoluted I can assure you. You can see the output of the example (only a little bit of LaTeX) at this repo: or at Kristin Linn's README, which was used as an example here: What is the function actually doing New_html = pandoc(new_md, format = "html")Īnd you can view the html using browseURL: browseURL(new_html) New_md = file.path(tempdir(), "README.md") The parse_latex command has an example from one of my other repos and you can run it as follows (need curl): rmd = file.path(tempdir(), "README_unparse.rmd") I still don't get it – show me an example You only need to change bad_string if you happen to have text in your README that matches this (should be rare as they are a bunch of Z's, unless you write like someone sleeping). The bad_string is something I'm using in the code. The text_height is how large the LaTeX should be (this may be bad for your document), the insert_string is the HTML the LaTeX is subbed for, the raw_git_site uses to reference the figures directly with proper content-type headers (so that they show up). The rest of the arguments are for inserting the LaTeX into the document. If you don't know what that means, just leave as master. The git_branch allows you to specify which branch you are on, if necessary. 
The git_username and git_reponame must be specified with your username and repository name, respectively. One example would be rmd = "README_with_latex.md" and md = "README.md". The new_md is the filename for the output md file that you wish to create. This md is located in a temporary directory and won't write to the directory of the README. If the README has an rmd or Rmd extension, the README is first knitted using knit(rmd) and then the resultant md file is used. You must put in a README file as the rmd argument. Let's see it's arguments: args(parse_latex) It's not the best function name for what it does, but I don't really care. You would then load the package: library(latexreadme) Install_github("muschellij2/latexreadme")
#LATEXIT ONE RMD FILE INSTALL#
You can install the package using: library(devtools) I wrote an R package that would parse a README.md (or README.rmd if it's RMarkdown). I didn't allow options for putting them in a sub-folder, but may incorporate that.
This generally assumes you have a GitHub repository (have no idea what others use), and that you're OK with the figures being located in that GitHub repository. I wrote this for R code, which can use dollar signs for referencing and never has double dollar signs. I assume any code that involves dollar signs be demarcated by chunks starting with three backticks (“). I could encorporate other delimiters such as [, but I did not. This only works for inline equations marked with dollar signs ($) or equations marked by double dollar signs ($$). I have done a bit of parsing in the past, but I was either too lazy to think about the right regex to do, couldn't think of it easily, or thought my solution was sufficient even if not elegant. I opted to try a more generic solution for (4.) using some very hackey text parsing. #LATEXIT ONE RMD FILE MAC#
Use LaTeXIt (for Mac OS) or other converter to make your equations and embed them. These are good options, but 1) they may go away at any time, and 2) require you to rewrite your md file. GitHub parsing is done by SunDown and is secure, therefore won't do LaTeX. It cannot (and in some cases, shouldn't) be done. Apparently, many others ( 1, 2, 3 ), have asked the same question. I have many times wondered about getting LaTeX math to render in a README file on GitHub. The Problem: GitHub README.md won't render LaTeX
