linux - Is there a lower level interface than `std::process::Command` to execute a single string as a process? -


is there equivalent in rust like:

os.run("/bin/bash ln -s /dir1 /dir2");

i want ability spawn process using string expression similar 1 use in ptty.

the utility i've found doing std::process::command, it's not documented , seems complex , hard debug.

there in rust, how invoke system command , capture output? gives std::process::command answer, hence why specified finding possible option. however, i'm looking lower level interface make std::process::command execute single string query rather forcing me feed arguments 1 one.

no, there no such thing available in standard library. mentioned in comments, command is lower level interface. shells , other tools take single string have exceedingly clever parsing of string in order split pieces. parsing non-trivial , may differ between shells!

you can write own simplified parser, of course:

use std::process::command;  fn main() {     let args = "ls -l /etc /tmp";     let args: vec<_> = args.split(" ").collect();      let output = command::new(args[0])         .args(&args[1..])         .output()         .expect("couldn't run it");      println!("{:?}", ::std::str::from_utf8(&output.stdout));     println!("{:?}", ::std::str::from_utf8(&output.stderr)); }

but it's not documented

i'm biased, don't understand how more documented. every useful method has prose describing , examples demonstrating it.

and seems complex

i'm not sure why; perhaps amount of choice overwhelming, realistically control needed.

and hard debug.

i'm not sure debugging needs done — either code compile or not, execute or not. compiler errors useful, runtime errors of nature depend on os.

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() .
