Starting a web browser

From Rosetta Code
Starting a web browser is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Build and show a web page displaying the data from the task separate the house number from the street name in a formatted and colored table.

Task

Write the code which automatically opens a web page in a browser showing the addresses. No static data must be shown, only processed data.


EchoLisp

Since we are already in a browser window, the browser is started. print-hatml sends an html string to the standard output area. The table is styled with the "htable" css class, which is included in EchoLisp. <lang scheme>

table from "Separate_the_house_number_from_the_street_name"

(print-html (table->html adresses)) </lang>

Output:

Perl

Borrowing code from the Separate the house number from the street name task.

Translation of: Perl 6

<lang perl>use File::Temp qw(tempfile);

my @addresses = ( 'Plataanstraat 5', 'Straat 12', 'Straat 12 II', 'Dr. J. Straat 12', 'Dr. J. Straat 12 a', 'Dr. J.

my @row_color = ('#d7fffe', '#9dbcd4');

  1. build the table

sub genTable {

my $table = '

' . qq|\n|; 
   my $i = 0;
   for my $addr (@addresses) {
$table .= qq||; 
       my($street,$number) =  $addr =~
       m[^ (.*?) \s+
           (
              \d* (\-|\/)? \d*

$table .= qq|\n|; 
   }
return $table . '
AddressStreetHouse Number
$addr$street$number

';

}

my $streets_and_numbers = genTable();

  1. generate the page content

sub content { return <<END; <html> <head> <title>Rosetta Code - Start a Web Browser</title> <meta charset="UTF-8"> </head> <body bgcolor="#d8dcd6">

Split the house number from the street name

$streets_and_numbers

</body> </html> END }

  1. Use a temporary file name and file handle

my ($fn, $fh) = tempfile :suffix('.html');

  1. dump the content to the file

open my $fh, '>', $fn; print $fh content(); close $fh;

  1. use appropriate command for X11 (other systems will need different invocation)

my $command = "xdg-open $fn";

  1. start the browser

system "$command";

  1. wait for a bit to give browser time to load before destroying temp file

sleep 5; </lang>

Perl 6

Works with: Rakudo version 2017.09

Uses the code from the Separate the house number from the street name task almost verbatim. Included here to make a complete, runnable example.

my @row-color = '#d7fffe', '#9dbcd4';

  1. build the table

sub genTable () {

my $table = '

' ~ qq|\n|; 
   my $i = 0;
   for $addresses.lines -> $addr {
$table ~= qq||; 
       $addr ~~ m[
           ( .*? )
           [
               \s+
               (

               )
           ]?
           $
       ];
quietly $table ~= qq|\n|;
   }
$table ~ '
AddressStreetHouse Number
{$addr}{$0.Str}{$1.Str||}

';

}

  1. generate the page content

sub content { 

   qq :to /END/;
   <html>
   <head>
   <title>Rosetta Code - Start a Web Browser</title>
   <meta charset="UTF-8">
   </head>
   <body bgcolor="#d8dcd6">

Split the house number from the street name

{ genTable } 

   </body>
   </html>
   END

}

  1. Use a temporary file name and file handle

my ($fn, $fh) = tempfile :suffix('.html');

  1. dump the content to the file

$fh.spurt: content;

  1. use appropriate command for Windows or X11
  2. other OSs/WMs may need different invocation

my $command = $*DISTRO.is-win ?? "start $fn" !! "xdg-open $fn";

  1. start the browser

shell $command;

  1. wait for a bit to give browser time to load before destroying temp file

sleep 5; </lang>

Output:

Will start the default browser (or open a new tab/window in a running one) and display this table.

  1. Construct the HTML to show

set html "<html><head><meta charset=\"UTF-8\"> <title>split_DE_NL_address</title></head><body>

"

foreach streetAddress [split $data "\n"] { 

   set streetAddress [string trim $streetAddress]
   if {$streetAddress eq ""} continue
   lassign [split_DE_NL_address $streetAddress] str num
append html ""

}

append html "
AddressStreetNumber
$streetAddress$str$num

</body></html>"

  1. Pick a unique filename with .html extension (important!)

set f [file tempfile filename street.html] fconfigure $f -encoding utf-8 puts $f $html close $f

          1. THE WEB BROWSER LAUNCH CODE MAGIC #####
  2. Relies on the default registration of browsers for .html files
  3. This is all very platform specific; Android requires another incantation again

if {$tcl_platform(platform) eq "windows"} { 

   exec {*}[auto_execok start] "" [file nativename $filename]

} elseif {$tcl_platform(os) eq "Darwin"} { 

   exec open $filename

} else { 

   exec xdg_open $filename

}</lang>
