You need to use double-quotes for escape sequences, see about_Special_Characters.

An example for you to test:

You can use single quotes as delimiter with qx like this:

All credit goes to @rawr's comment to the question, just formalizing it with an answer:

The secret is in the roxygen2 documentation: just add the following to the end of the package DESCRIPTION file:

(This should be a comment rather than an answer, but I'm still building 'reputation' points, so...)

If Passenger has the same UID that myservice needs to run, then that's not where the problem lies. Nor are the other ways of launching a child likely to change the outcome.

I suggest capturing the output of the subprocess as follows: systemctl --user start myservice > /tmp/systemctl.output 2>&1 and then inspecting the output file after the subprocess fails.

As @Louys pointed out in the comment above, use SweetAlert2 (the latest)

The short answer is NO.

The workaround is to use parameterised inputs or to use double single quote '' to escape quotes manually. If you have existing scripts to convert a simple regex could be used to clean them up. In SQL the resuling SQL would be similar to this:

You may use an anonymous function

In short, yes, it's legal.

The concept of an identifier is a syntactic one: when parsing Raku, the parser needs to classify the things it sees, and the identifier rules indicate what sequences of characters should be recognized as an identifier.

By contrast, stashes, method tables, and lexical scopes are ultimately hash-like data structures: they map string keys into stored values. Just as there's no limit on what keys one can put into a hash, there's not one here either. Given meta-objects can be user-defined, it's unclear one could reliably enforce limits, even if it was considered desirable.

The ::(...) indirect name syntax in declarative contexts comes only with the restriction that what you put there must be a compile-time constant. So far as parsing goes, what comes inside of the parentheses is an expression. The compiler wants to get a string that it can use to install a symbol somewhere; with identifiers it comes directly from the program source text, and with indirect name syntax by evaluating the constant that is found there. In either case, it's used to make an entry in a symbol table, and those don't care, and thus between the two, you have a way to get symbol table entries that don't have identifier syntax.

You can let .Rmd generate .md output instead of the default .html by setting options(blogdown.method = 'markdown') in your .Rprofile. See this section in the blogdown book.

Then restart R, delete index.html, and serve the site again.
