RMarkdown mid-line Decimal Place for Lancet - format

I'm writing an article for a Lancet Journal, which infuriatingly require the decimal place to be a placed mid-line (ie, 23·4, not 23.4). I typically write my articles in RMarkdown for reproducibility reasons (very easy to track numbers in the code to where they appear in the paper).
Does anyone know a way to tell RMarkdown renders (to a word doc) to use the mid-line · for all decimal places instead of the standard .? I can go through the paper and change them all manually but the whole point of using RMarkdown was to not have to do that kind of thing.

This might be pretty easy using a document hook. That is an R function that is given the output from knitr to process before passing it to Pandoc to convert to Word. The only tricky part is recognizing the difference between decimal points and periods that you don't want to convert.
I'll assume every number you display that has a decimal point has a digit on either side of it, like 23.4 does, but 23. doesn't, nor does .3. If that's true, you just need to add this code to your document, probably in the setup chunk (but I don't think it really matters where):
middecimal <- function(s, ...) {
gsub("([[:digit:]])[.]([[:digit:]])",
"\\1·\\2", s)
}
knitr::knit_hooks$set(document = middecimal)
Then you'll end up with a display like this from the demo RMarkdown document, modified to add this:

PDF - Edit raw text without special paid tool

Is there a way to edit the raw text from a PDF without any special paid software?
So there are PDFs with highlightable text. I assume that the text is stored somewhere in the file.
I tried to just drag & drop a PDF into vscode but it just showed me unknown characters; even a little of meta text but if I edit the meta-infos, the file gets mostly corrupted.
Apart from that, I could not find any of the text contents of my desired PDF in vscode-editor.
Does someone know if there is a solution like inspecting and changing the source code somehow without a special software? I want to edit the contents; not the meta-infos.
(I use macOS)
The text you see on a pdf page can be constructed in dozens of different ways, actually there are millions of users, using potentially hundreds if not thousands of different methods.
Update
The question is MacOS but for native cross platform you need to work in mime text/pdf to be universally useful. But by way of example how thats possible specifically in windows its possible to write line by line using say cmd here is a snippet of what was a few dozen lines :-)
echo %%PDF-1.0>demo.pdf
echo %%µ¶µ¶>>demo.pdf
echo/>>demo.pdf
for %%Z in (demo.pdf) do set "FZ1=%%~zZ"
echo 1 0 obj>>demo.pdf
echo ^<^</Type/Catalog/Pages 2 0 R^>^>>>demo.pdf
echo endobj>>demo.pdf
echo/>>demo.pdf
For the fuller "Feature Creep"ing of now over more than a 100 lines and counting see
https://github.com/GitHubRulesOK/MyNotes/raw/master/MAKE-PDF.cmd
However although plain text could be the simplest it is rarely used except to prove a conceptual point that it is possible. The rest of the time "Special Software" as you call it (a pdf generator/editor) will be used to compress the file objects, most frequently as different optimal binary streams.
So some text may be scanned pixels whilst other text may be line shapes that look like letters, or at other times plain letters without fonts but a named style, or even letters with the font included (embedded) in the file (the preferred option).
In many ways each page may be built different to the others and thus no two pdfs generally will use the same structure unless like a bank statement using a format that does not change much from month to month, even if the balance wobbles about.
So in summary the tool that will work best is the one that covers every single permutation that Adobe dreamed of, and still keep the result a valid Adobe PDF.
Thus Acrobat PRO 3D is on my shelf (even if not used from one year to the next)
There are many cheaper editors and ones I will use more often for small mods are Tracker Xchange and FreePDF PRO and both have different limitations.
Your choices for MacOS will be more limited thus search for the best you are willing to pay for.

Rename latexmath macro in asciidoc

Is there a way I can rename or alias latexmath in an AsciiDoc document?
In an ideal world, I'd like to set up an AsciiDoc such that $...$ is interpreted as LaTeX math, and
$$...$$ is interpreted as a block equation. In general, I'm just trying to reduce the number of characters involved in defining a math block since
where $c$ is the speed of light and $m_0$ is the rest mass
is significantly more readable (to someone who's used LaTeX for years) than
where latexmath:[$c$] is the speed of light and latexmath:[$m_0$] is the rest mass
The use case I have is that I'm writing technical documentation for upload to a GitLab repository. I'd like to be able to exploit GitLab's ability to automatically render AsciiDoc format files. However, these documents are math heavy, so I find the large numbers of latexmath:[...] blocks hard to read while editing.
latexmath is the name of the macro that handles parsing the LaTeX markup. If you don't specify latexmath, asciidoctor doesn't know to pass control to an alternate parser.
You could achieve what you're after by writing a pre-processing step that identifies contiguous blocks of LaTeX markup and wraps that markup in latexmath:[...]. The updated markup can then be processed by Asciidoctor like normal (assuming that your LaTeX markup identification is accurate). How you go about implementing that is up to you.
Another way, assuming you have some Ruby skills, would be to modify the extension that implements the latexmath macro such that it was called, say, L. Then your markup would be the more concise:
where L:[$c$] is the speed of light and L:[$m_0$] is the rest mass

Use Python to generate input to XeTeX

I am wondering what is a good way to use Python to generate an arithmetic worksheet consisting only of 2-digit numbers squared. Specifically I want to be able to call upon a Python program in which it asks me for parameters such as the range of the numbers in can call upon to square and the number of questions I want to generate. Once that is done the program will generate the numbers and then automatically open up a .tex file (already with preamble and customizations) and basically do a loop for each question like this:
\begin{exer}
n^2
\end{exer}
%%%%%Solution%%%%%%
\begin{solution}
n^2=n^2
\end{solution}
for some integer n.
Once it is done writing the .tex file then it will run xetex and output the pdf ready to use and print. Any help or suggestions? Python is preferred but not mandatory.
Actually your problem is so simple that doesn't require any special magic. However I would suggest you don't try to append your generated content into a file you already have with preamble, good practice is to leave it untouched and include (in fact you can copy it on generation or use TeX \include).
Now, let's add more to the generation. Python formatter is your friend here, you use the example you've given as a template, and write the product into a file in every iteration. Don't forget to escape "{" brackets, as they're symbols used by formatter.
At the end, (suggestion) you can subprocess to launch XeTeX - depending on your need call() is enough or use popen().

Using Subscript and Superscript in Processing 2?

I'm trying to achieve something along the lines of:
Water = H^2O
Is this possible in Processing 2.2?
There are a couple options. If you only want a few simple super/subscripts, you might as well just use unicode:
String s = "H\u2082O";
text(s,10,20);
Where \u2082 is unicode for the ₂ character. If you want more advanced control, you could use this code from the processing forum, which can super/subscript whatever you want, rather than hardcoding the characters. The code is too big to copy here, but you should be able to include the SuperSubText class in your sketch and then use formatting strings like H<sub>2</sub>O in your code.

manually finding the size of a block of text (ASCII format)

Is there an easy way to manually (ie. not through code) find the size (in bytes, KB, etc) of a block of selected text? Currently I am taking the text, cutting/pasting into a new text document, saving it, then clicking "properties" to get an estimate of the size.
I am developing mainly in visual studio 2008 but I need any sort of simple way to manually do this.
Note: I understand this is not specifically a programming question but it's related to programming. I need this to compare a few functions and see which one is returning the smallest amount of text. I only need to do it a few times so figured writing a method for it would be overkill.
This question isn't meaningful as asked. Text can be encoded in different formats; ASCII, UTF-8, UTF-16, etc. The memory consumed by a block of text depends on which encoding you decide to use for it.
EDIT: To answer the question you've stated now (how do I determine which function is returning a "smaller" block of text) -- given a single encoding, the shorter text will almost always be smaller as well. Why can't you just compare the lengths?
In your comment you mention it's ASCII. In that case, it'll be one byte per character.
I don't see the difference between using the code written by the app you're pasting into, and using some other code. Being a python person myself, whenever I want to check length of some text I just do it in the interactive interpreter. Surely some equivalent solution more suited to your tastes would be appropriate?
ended up just cutting/pasting the text into MS Word and using the char count feature in there
