"my" variables are lexically scoped to the curly braces that contain them. That means that your $IAm is limited exactly to that init block. Also, =~ isn't in perl6. You can put "my $IAm" outside that block and assign to it inside the block, though. HTH - Timo

Re: issues with

Hey, X11::Xlib::Raw is buggy. It has to have all modules it uses internally inside its "provides" section in the META6.json, otherwise "use" will not find them. I'll open a ticket with the module author. HTH - Timo On 08/03/17 22:08, ToddAndMargo wrote: > Hi All, > > What is wrong with this?

Hi, Wouldn't it be enough to use something that backtracks? As you might know, "token" is "regex + ratcheting" and "rule" is "token + sigspace". HTH - Timo

Re: debugging modules

Heyo, the way the debugger works is by changing the compiler to generate code that communicates with the debugger at every step. That means that if you want a module to be debuggable, it has to be compiled by the debugger's compiler, too. There's apparently currently no way to just force a full

I don't quite understand what's wrong with just my $TheValue = $?FILE.subst(/.* "/"/, "" :g); near the top of your module?

Re: Question for the developers on splice

Shifting from the front will just move the "beginning" pointer one slot forwards, and popping will decrease the "element count" number. I'm not sure if splice with an empty "insertion" list that happens to be at the end will also just reduce the number of elements or if it does a bit of unnecessar

Re: Can this OR be shortened?

I seem to recall you asked about performance recently the regex engine has a significant overhead. Your regex is equivalent to $Terminal.contains('xterm' | 'linux') though of course if you only test this once at the beginning of the program, you can ignore that.

Re: Failed to open file .. too many open files

i highly suggest you slurp instead of open + slurp-rest, because that will automatically close the file for you, too. other than that, you can pass :close to the slurp-rest method and it'll also close the file. if you're not closing the files you're opening, you'll be relying on the garbage colle

Re: Failed to open file .. too many open files

Please use "$.source_dir/authors.txt".IO.lines instead of open + lines. with the former you're expressing you really only want to read all the lines out of the file and be done with it. when you open and then call .lines, you're saying nothing about what you want to do with the file handle afterwar

Re: regex and performance question

Yeah, junctions are super useful, but not very fast. compare these two pieces of code: so "hello how are you today?".contains("hello" & "u t") for ^1_000_000 and my $target = "hello how are you today?"; so $target.contains("hello") && $target.contains("u t") for ^1_000_000 On my machi

Re: "not" question

" }' Yes This uses a "none" junction, which takes part in the whole junction evaluation process, as opposed to the prefix: which just negates a value straight-up and doesn't know it's being used inside a junction. HTH - Timo On 27/03/17 19:11, Timo Paulssen wrote: >
