The following library does equivalent job in English and could be forked to change the language or support different ones: https://www.npmjs.com/package/time-ago-pipe npm install time-ago-pipe –save Then in the @NgModule you want to use it in: import {TimeAgoPipe} from ‘time-ago-pipe’ @NgModule({ imports: [… etc …], declarations: [AppComponent, …etc…, TimeAgoPipe], bootstrap: [AppComponent] }) And in the template: … Read more
I think you misunderstand communicate… http://docs.python.org/library/subprocess.html#subprocess.Popen.communicate communicate sends a string to the other process and then waits on it to finish… (Like you said waits for the EOF listening to the stdout & stderror) What you should do instead is: proc.stdin.write(‘message’) # …figure out how long or why you need to wait… proc.stdin.write(‘message2’) (and if … Read more
No, it is not ok. All commands in a pipeline execute at the same time, and the shell prepares redirections before executing the commands. So, it is likely that the command will overwrite the file before cat reads it. You need sponge(1) from moreutils.
Yes it is possible in TypeScript code. You’ll need to call the Pipe’s transform() method. Your template: <h2>{{ fullName }}</h2> In your .ts: import { TitleCasePipe } from ‘@angular/common’; export class App { fullName: string = ‘ramesh rajendran’; constructor(private titlecasePipe:TitleCasePipe ) { } transformName(){ this.fullName = this.titlecasePipe.transform(this.fullName); } } You’ll need to add TitleCasePipe in … Read more
Working with named pipes on Windows Node v0.12.4 var net = require(‘net’); var PIPE_NAME = “mypipe”; var PIPE_PATH = “\\\\.\\pipe\\” + PIPE_NAME; var L = console.log; var server = net.createServer(function(stream) { L(‘Server: on connection’) stream.on(‘data’, function(c) { L(‘Server: on data:’, c.toString()); }); stream.on(‘end’, function() { L(‘Server: on end’) server.close(); }); stream.write(‘Take it easy!’); }); server.on(‘close’,function(){ … Read more
You can use the following construct: <(command) So, to have bash create a FIFO with the command as the output for you, instead of your attempted -i [“${inputData}”], you would do: -i <(echo “$inputData”) Therefore, here is your final total command: executable -v -i <(echo “$inputData”) -o outputFile.eps
Use the subprocess module: import subprocess command = [‘ls’, ‘-l’] p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.IGNORE) text = p.stdout.read() retcode = p.wait() Then you can do whatever you want with variable text: regular expression, splitting, etc. The 2nd and 3rd parameters of subprocess.Popen are optional and can be removed.
It should be ok if you use both tee and mkfifo. mkfifo pipe cat pipe | (command 1) & echo ‘test’ | tee pipe | (command 2)
If you want to redirect the output of one program into the input of another, just use a simple pipeline: program1 arg arg | program2 arg arg If you want to save the output of program1 into a file and pipe it into program2, you can use tee(1): program1 arg arg | tee output-file | … Read more
Braces define an anonymous function, called a block. Tokens between the pipe are the arguments of this block. The number of arguments required depends on how the block is used. Each time the block is evaluated, the method requiring the block will pass a value based on the object calling it. It’s the same as … Read more
