regex - Get multiple matches from text in curly braces -


i have sample file:

authoritative;  subnet x.x.x.x netmask x.x.x.x {     range x.x.x.x x.x.x.x;     deny unknown-clients;     default-lease-time 86400;     max-lease-time 86400;     option domain-name "bla";     option domain-name-servers x.x.x.x;     option broadcast-address x.x.x.x;     option subnet-mask x.x.x.x;     option routers x.x.x.x;      host host1 {         hardware ethernet 00:e1:4c:68:00:53;         fixed-address 1.1.1.1;     }      host host2 {         hardware ethernet 01:e2:4d:69:01:54;         fixed-address 2.2.2.2;     }      host host3 {         hardware ethernet 02:e3:4e:70:02:55;         fixed-address 3.3.3.3;     }      host host4 {         hardware ethernet 03:e4:4f:71:03:56;         fixed-address 4.4.4.4;     }      host host5 {         hardware ethernet 04:e5:5f:72:04:57;         fixed-address 5.5.5.5;     } }

now i'm trying extract mac address , ip address parts within host x blocks. when use file structure (that includes newlines) doesn't match @ all... i'll address later on. i'm having hard time getting matches. have far: link myregex can see there, $1 , $2 contain last mac / ip address entries. how matches entries in sample file? i'm sure i'm missing essential...

thanks lot!

host.*?\{\s*hardware ethernet\s+(?:((?:[0-9a-fa-f]{2}:){5}[0-9a-fa-f]{2});\s*fixed-address\s+((?:\d{1,3}.){3}\d{1,3}));\s*\}

tested here.

explanations

\s*\}\s*\} matching 1 closing brace many @ end of pattern.

[0-255] translates digits between 0 , 2, or 5. not want. it's easier use \d{1,3} here.

\sfixed-address need \s*fixed-address here since may have several spaces before fixed-address.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
