I have a piece of asyncronous code I would like to run at a later date. I figured a Promise would suit this purpose fine.

So far this is what I have:

sub makePromise ( $o, $m, :$in = 0, :$args = @() ) {
  my $p = Promise.new;

 for $args {

  RakuAST::Statement::Use.new(

  ),

    name => RakuAST::Name.from-identifier("route"),
    args => RakuAST::ArgList.new(
      RakuAST::Block.new(
        body => RakuAST::Blockoid.new(

Over the weekend, I wrote a module to do just that. It's early days still, as I'm sure there are tags that are not covered. I'll need to find the spec and have a nice long sit down before it's complete.

Here's what I have, though.

Have fun!

The BQN list operator ‿ can readily transfer into Raku. It's basically the same as Raku's list operator: ,. There is a small devil in the detail and that can be illustrated in the following example:

multi sub infix:<‿> ($a, $b) { 
  infix:<,>($a, $b) 
}

say 1‿2‿3; # ((1 2) 3)

I was just introduced to BQN, recently. While it won't be my first choice of language until I understand it a lot more, it does provide an interesting insight into all things Listy.

So I thought I might grab some low hanging fruit and bring some of that BQN goodness into Raku, a language that I -am- using on the daily.

Here's an implementation for the Range operator (↕):

multi sub prefix:<↕>(List() $l) {

I went to [bart.gooogle.com] and asked it: "How do you write lambda functions in Raku?"

Here's how it responded:

To write lambda functions in Raku, you can use the following syntax:

Code snippet

Xliff

raku -Ilib -e 'use experimental :rakuast; use MONKEY-SEE-NO-EVAL; my $ast = RakuAST::Statement::Need.new( module-names => [ RakuAST::Name.from-identifier(RakuAST::Name.from-identifier("GLib::Raw::Definitions")) ] ); EVAL $ast; import ::("GLib::Raw::Definitions"); glib.say'

This is the exact testing data. It's execution ready if you clone p6-GLib, you should only need to change into the project directory and run the above. Otherwise you will have to create a .rakumod file with a constant declaration and replace the glib in the above script with the name of that constant.

So I needed to access the symbol table of one of my modules, recently. After a few hours on the web (and after wracking my brain for a bit) I came up with the following:

sub getSymbolTable (\T, $cu-name) is export {
  return Nil unless $cu-name;

  my $nodes = $cu-name.split('::').Array;
  my $fn    = $nodes.shift;
 my $st = T.WHO{$fn};

Does anyone see a problem with this? If so, I will submit the PR.
