Kaz Wolfe

what did you break

TheWanderer

in Android on Stack Overflow Chat, 24 secs ago, by TheWanderer

if I'm using String.substring("multiplecharstring"), is there a way to get the index of g instead of m?

Kaz Wolfe

yes.

TheWanderer

how

Kaz Wolfe

1:50 AM

docs.oracle.com/javase/7/docs/api/java/lang/…

TheWanderer

so currentText.substring(currentText.lastIndexOf(m.group().lastIndexOf(m.group().l‌ength())))?

Kaz Wolfe

what the hell are you doing

you want a substring starting at the end of somestring?

Seth

@TheWanderer Java...

Android Dev

@Seth Yeah well the only other choice on Android is C++. (Well, there's Kotlin but I'm not quite sure everyone should jump on the bandwagon just yet)

Seth

@TheWanderer Just found a very odd bug

TheWanderer

@AndroidDev crashes on vol press? fixed

Seth

totally a frontend problem.

;P

TheWanderer

@KazWolfe no when you do indexOf("string") it returns the index of "s"; I want the index of "g"

Android Dev

@TheWanderer no. See HTYD

TheWanderer

idk what's going on

Kaz Wolfe

2:09 AM

@TheWanderer indexOf("string") + "string".length()

TheWanderer

and for some reason + string.length() doesn't work

Android Dev

Shall I get the stack trace?

TheWanderer

yes

Kaz Wolfe

sorry, i can't help too much right now. i have three blocker JIRAs right now that need to be solved tonight.

Android Dev

@TheWanderer Well well looks like our friend NPE is back: paste.ubuntu.com/24789653

isn't there a vaccine for that yet?

@Zanna Yes, but it only works on people.

Egad, reminds me of that "wonderful" sign. This was in one of those collections of horrible translations: "Dr. So and So, specialist in women and other diseases".

Zanna

and I very like it

Zanna

10:37 AM

@Benny thanks! seems a lot of people liked that one for some reason!

TheWanderer

11:26 AM

@terdon you know regex right?

terdon

Yeah

TheWanderer

I need some help again

terdon

Shoot

TheWanderer

I have this regex \B@(.+?)\b, but I need to replace \B with something that will either match the beginning of the input or a space

but not just any boundary

terdon

@TheWanderer In what regex flavor? What tool/language?

TheWanderer

11:28 AM

Java

terdon

I think that uses some sort of PCRE, right?

TheWanderer

I've been looking here but idk what I'm looking for

and I don't know how it works

terdon

Anyway, try (^|\s+)@(.+?)

Or, to use a non-capturing group:

(?:^|\s+)@(.+?)

TheWanderer

first one doesn't quite work, trying second

same effect

the usage is I need to account for multiple occurences

terdon

What's your input? Are you sure it's the beginning of the string?

@TheWanderer Of what?

TheWanderer

11:32 AM

of @whatever

so like @hi and some text @hue

terdon

@TheWanderer Then why are you using .+? instead of .+

?

TheWanderer

well I only want to capture one at a time

terdon

The ? means "make it the shortest match" so it will stop as soon as one chatacter is found.

TheWanderer

oh

I don't know regexes :p

terdon

Ah no, sorry, not with the \b

TheWanderer

11:33 AM

yeah

terdon

The \b means it will continue until the first \b is found.

But it still won't find all of them. That will need a while loop or some sort of global operator if java has that.

TheWanderer

well

Pattern.compile is supposed to find every match

Pattern p = Pattern.compile("(?:^|\\s+)@(.+?)\\b");
                        Matcher m = p.matcher(currentName);

                        try {
                            while (!m.hitEnd()) {
                                if (m.find()) {
                                    currentName = m.group().replace("@", "");
//                                    Log.e("NAME", currentName);
                                }
                            }
                        } catch (IllegalStateException e) {

you use a matcher and loop with that

terdon

Why are you escaping the slash? Why \\s instead of \s ?

TheWanderer

m.find() finds the next occurence if it exists and then m.group() returns that occurence

that's how Java regex works

you need to use double escapes

terdon

Yes, I see. OK.

TheWanderer

11:38 AM

\B@(.+?)\b works for the most part, but because \B is checking for any border, sometimes it replaces the wrong string (I think)

terdon

That's, uhm, annoying. Does that mean you also need to escape the OR( the |)?

TheWanderer

no

but I don't think | is actually a valid regex in Java

terdon

But the regex is fine as far as I can tell.

@TheWanderer It is.

X|Y	Either X or Y

TheWanderer

huh

terdon

On the page you linked to.

TheWanderer

11:39 AM

weird it doesn't highlight it

terdon

Highlight?

TheWanderer

my IDE

terdon

Oh.

So what are you parsing? What's your input?

TheWanderer

hmm this is awkward lol

the regex is fine

I was just using an indexOf() where I should have been using lastIndexOf() :p

terdon

But you have extra whitespace after the beginning of the string?

@TheWanderer Ah :)

TheWanderer

11:41 AM

of course, this won't work if someone goes to a previous ping in the text to edit it..

but I think I need to leave that up to @NathanOsman >_>

Rinzwind

Android Dev

@Rinzwind So you wanna be an alpha tester of our app?

I can promise you lots of crashes :D

@TheWanderer wat. Yes it does work if you edit a previous one

@AndroidDev to be fair, it's a pretty sepcific case I'm predicting, but if you have, say @TheXed @AndroidDev @TheWanderer and go back to change TheXed to something else, it'll replace @TheWanderer

if you type in THE or less

Android Dev

@TheWanderer Oh, I see what you mean. BTW, you saw this?

in HueToYouDevs, 2 hours ago, by Android Dev

@TheWanderer Found another bug. Type anything into the AUGR message box and hit back. It crashes.

TheWanderer

yup

fixed it just now

Android Dev

That's what you said yesterday :P

TheWanderer

well that was a different NPE

Android Dev

@TheWanderer Well I just found another bug :( I can't tell you for sure what happened, but it seems that the app got paused and when I reopened it from the running drawer the color of the show chats FAB was the color set in the settings and not the automatic color

TheWanderer

2:18 PM

these are pretty late-game bugs to fix

we really need to wait for ahem @NathanOsman ahem

@SeverusTux sorry, no idea how to solve it :)

Severus Tux

cl-netbox

@SeverusTux are the settings the same as in ubuntu ?

Severus Tux

4:43 PM

the /etc/NetworkManager/system-connections/Vodafone\ Vodafone\ Connect file is same

but /etc/NetworkManager/NetworkManager.conf in Arch is empty

@SeverusTux strange ... I upvoted the question :)

@SeverusTux is it possible that arch uses another file ?

Severus Tux

thankyou!

No, I am sure . it uses the same fiel

come on app.wire

cl-netbox

@SeverusTux did you try to copy the content from ubuntu into the file ?

Severus Tux

No, because ubuntu has some plugins. I am not sure copying the same would help. Let me give it a try

@SeverusTux done :)

Hi

Anyone using 17.04 with Unity7 here?

@SeverusTux Are you sure the device is cdc-*?

You connected it into the USB port right?

Zanna

@AndroidDev I'd love to test it if it will run on any of my devices

Severus Tux

@Anwar Yes, the device is cdc-wdm0

Anwar

Have you manually edited the file in /etc/NetworkManager or it was generated by gui?

Severus Tux

It was generated by gui

Anwar

5:13 PM

and you hand edited it later?

Severus Tux

Yes, I added "password-flags=1"

Anwar

why?

cl-netbox

@SeverusTux why ? does it work when you remove this ?

Severus Tux

because it was not working before, same problem, So I copied it from Ubuntu's config file

now its not there

Anwar

From my experience, if you hand edit a gui generated connection file, it won't work. I don't know the reason

Severus Tux

5:15 PM

I completely removed /etc/NetworkManager and reinstalled NetworkManager

the problem persists

Anwar

Well, does your device have a led indicator?

cl-netbox

@Anwar I can confirm the same ... for whatever reasons sometimes it generates problems :)

Severus Tux

Yes

It shows green

even I get " Vodafone (HSUPA) " in my nm-applet . But when I click on it, nothing happens

When I try it from cli,

I get this :

 $ nmcli device connect cdc-wdm0
Error: Timeout 90 sec expired.

Anwar

have you tried disconnecting and then reconnecting?

Severus Tux

You mean removing the device ?

Anwar

5:23 PM

yes

cl-netbox

@SeverusTux can it be that the MAC address of the device and the IP address don't correspond correctly ?

Severus Tux

yes I have done it many times

But, unlike Ubuntu, I don't have a "enable mobilebroadand"

option

Anwar

I'm out of suggestions. sorry

cl-netbox

@SeverusTux ah ... that might be the problem ! maybe you have to install a separate package for this in arch ? :)

Severus Tux

no, its enabled by default

cl-netbox

5:31 PM

@SeverusTux hmmm ... then I'm running out of ideas - sorry :(
