Thanks, coderus. It's not just the 24/7 presence, I find IRC generally a pain to use. It's kinda OK for an immediate interaction but otherwise... Too much irrelevant info ("XY has joined/left"), no threading, no easy search... Basically if I have a question that has been already asked and answered 200 times, the only way to get the answer is to get online and ask again, hoping that someone who knows the answer is also online. It's just way too much effort.
Mailing lists are only marginally better. The best medium for getting answers are Usenet newsgroups, but very few youngsters even know such a thing exists.

The best way you can use IRC is to have a 24/7 server that is logged on to the channels you are intrested on, and ircnotify set up to email a ping to you if something that interests you happens...)
As for usenet, yes, that is the coolest thing since fridges
As it happens I run our company-internal news server (inn2), with a fair amount of traffic (301 articles posted last week, just checked now)

news is what got me hooked on the internet (well, gopher and e-mail as well). I always found it (and still find it) much more comfortable and elegant to use than "modern" internet forums. I especially hate the jolla forum. I really cannot find my way around it.

Another silly question. (My QML is not very good. I have done some Qt but I am mostly an embedded dev novadays and my idea of a UI is flashing an LED through GPIO 
)
How does one iterate through a string in QML? The QML documentation on the topic is rather sparse and I find the Qt discussion forum even worse to navigate than TJC, however unlikely that may seem.
Basically, I want to check if all characters in a string are from a given set. I tried...
Eventually I had to resort to a nested for loop, but there must be a better way.
Please note that this is for editing a QML for a Sailfish patch, i.e. I do not have the option to change the C++ source. Only pure QML please.

- foreach - no joy, my QML was rejected. Maybe I just did not hit the right syntax.
- QString::contains - that one was accepted but always returned true, no matter what I tried feeding it.

Code:
Component.onCompleted {

yourProperty.split().forEach(function(el,iterator){
//single character available in "el"
})
}
edit: But you might consider using regex on that string… should be even easier… or even something like if(string.indexOf(substring) > -1)

I tried this, but it would always return true, no matter what the contents of text was.
Replacing alphabet.contains() with my own function (another for loop) worked.
I have not tried indexOf() but if contains() did not work I am skeptical indexOf() would.
Thanks, I will try your forEach syntax when I get some time (in the next couple of hours or so).
EDIT1: Yey, your forEach works!
EDIT2: No, it doesn't. I forgot to save the file (
) and it was still picking up my old version. D'oh!
EDIT3: Thank you for your regex suggestion but my alphabet is more complex than that and contains some Unicode characters that give me even more headache

Code:
property string alphabet: "abcdefgh"
property string text
function isInAlphabet() {
for (var i = 0; i < text.length; ++i) {
if (!alphabet.contains(text[i])
return false
}
return true
}

oh, by the way, regex would look something like this:
Regular Expressions are around since basically forever and pretty fast in every implementation I can think of. Google "JS string match" for an even better alternative (match vs search, there's a difference).
Last edited by velox; 2015-10-29 at 13:35. Reason: "JS string match" would be even better ;)
Code:
if (string.search(/[^a-zA-Z]+/) === -1) {
// only characters
}
