Convert a TIO answer to a CMC answer

Question

Let's for once do something useful.

Given the text from a Try It Online codegolf submission, produce the equivalent Chat Mini Challenge submission, which is of the form

Language, N bytes: [`code`](URL)

or (if submission is a single byte – TIO will add a trailing s on the first line only if needed)

Language, 1 byte: [`code`](URL)

You may assume that the submission

• has only one line
• does not contain backticks (`)
• has no leading whitespace
• has a regular format like in the examples below; the code line is indented with four spaces ( ), not with HTML tags (<pre><code>…</code></pre>), i.e. no trailing whitespace.

Note that the submission may have a syntax highlighting tag. See last example.

You may optionally include the title text, i.e. …url "Language - Try It Online".

If you can, I could totally use some help with the regex. ><

Answer 5

05AB1E, 50 bytes

']¡J¦¦¦|J|`‚ʒнðQ}`ðÛ|D`θ'"Êi\|ë\}θ#1èr"ÿ: [`ÿ`](ÿ)

Try it online!

Now supports syntax highlighting too!

н is replaced by 0è and θ is replaced by ®è since those aren't pulled to TIO yet.

I just wonder how to shorten ¦¦¦...

Answer 7

MATLAB/Octave, 120 126 bytes

@(a)strjoin(regexprep(strsplit(a,'\n'),{'\[.+\]: (.+) ".+','^[\[<].+','# \[(.+)\](.+)','^ +'},{'`]($1)','','$1$2: [`',''}),'')

This should work. For MATLAB it won't work with Unicode characters though I don't think, mostly because MATLAB sucks when it comes to odd characters. However it will work with Unicode for Octave, or at least TIO seems to be able to cope.

It should also handle submissions both with and without the <-- --> syntax highlighting.

Updates:

1. Added 4 bytes as I missed the @(a) when copying over
2. Added 2 bytes to add back ticks around the code in the output

Answer 10

Pip, 43 39 38 bytes

[a@>3DC']": [`"g@-6|>s"`]("(g@v^s1)')]

Try it online!

Takes the lines as separate command-line arguments. An example invocation could look like:

> pip.py -f convert.pip "# [05AB1E], 1 byte" "" "    Ô" "" "[Try it online!][TIO-j3v72bss]" "" "[05AB1E]: https://github.com/Adriandmen/05AB1E" "[TIO-j3v72bss]: https://tio.run/##MzBNTDJM/f//8JT//zNSgSAnJycfDAA \"05AB1E – Try It Online\""

^{though actually this doesn't work for me because Windows cmd complains about the Ô... [inarticulate muttering]}

--At any rate, it works on TIO. Or, use the -r flag and take input from lines of stdin instead.

Assumes that the language name will not contain ] (which would break the markdown anyway).

Explanation

                                        g is list of cmdline args; a is 1st arg;
                                        s is space; v is -1 (implicit)
[                                    ]  Build a list with these elements:
 a@>3                                    1st line, sans first three characters,
     DC']                                 with the ] character deleted
         ": [`"                          This string
               g@-6                      6th line from the end (the code)
                   |>s                    with leading spaces stripped
                      "`]("              This string
                            g@v          Last line (containing the URL)
                               ^s         split on spaces
                           (     1)       get element at index 1
                                   ')    This character
                                        By default, the list is concatenated and printed
