Dear Pluto developers and users, I know that with Pluto, “print” goes to console, and that the (best?) way to get text displayed is to have cell result as markdown.
I wanted to have “versioninfo()” displayed, which prints only, so I cooked the following (originally without the commented “replace” line !)
# vinfo=replace(vinfo, "\n" => "\n\n")
Then I got all concatened text :
Julia Version 1.5.0 Commit 96786e22cc (2020-08-01 23:44 UTC) Platform Info: OS: Windows (x8664-w64-mingw32) CPU: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx WORDSIZE: 64 LIBM: libopenlibm LLVM: libLLVM-9.0.1 (ORCJIT, znver1) Environment: JULIA_EDITOR = vim
If I uncomment the “replace” line, then I correctly get line breaks, but, two of them for each line !
Does somebody know I could get single spaced consecutive lines ?
I’m guessing, but how about…
Not exactly elegant, but it does what you want. Ideally, you’d be able to insert
<br> for this, but Julia’s markdown parser isn’t a superset of html like standard markdown is.
let io = IOBuffer()
vinfo = mapreduce(l -> "- " * l, *, eachline(io; keep=true))
Alternatively instead of making it an unsorted list, you could wrap it in triple backticks or indent it by 4 spaces to indicate the text is pre-formatted. For some usecases involving preformatted text, this has the downside of generally being displayed in a fixed-width font.
let io = IOBuffer()
Ideally you wouldn’t have to resort to hacks like this and Pluto would give you some way of a cell outputting plain, unformatted text. If there really isn’t a way of doing this, I think it’d be worthwhile to open an issue for it. EDIT: submitted https://github.com/fonsp/Pluto.jl/issues/264.
Hey! You can use this combination of magic spell words:
I believe that
sprint does exactly the hack that you also invented (check the docs), and
Text is a wrapper around
str, such that when you
show it, it writes the original characters, not their escape codes.

md"`sprint` works by giving an `IOBuffer` as the first argument of the function that you gave. This only works if the function takes an `IO` as its first argument.
The `Pkg` functions take `IO` as an optional keyword argument, so we have to do another trick:"

Dear @non-Jedi, @lyonsquark, many thanks for your help, that also gave me useful hints to possible other uses in my future programmings (Markdown and IOBuffer ones).
Dear @fonsp, I am honored by your detailed answer ! And, it is a very clean solution that works perfectly. Also, I didnt know of “sprint(function)”, so I am really enlighted now.
Could I suggest that in some future (when you have time/ if it suits you) you put this tip in your FAQ, for future reference to other newbies ?
Thank you again for your help and the wonderful “Pluto” work !
