I would like to parse the following DocBlock / comment with regex. Code below
$subject = <<<HTML
/**
Theme Name: Hello world
*/
HTML;
$pattern = '/^\/(?:*)+Theme Name:(\s)?([\w]+)/';
preg_match($pattern, $subject, $matches);
print_r($matches);
Running the code output the following error..
Warning: preg_match(): Compilation failed: nothing to repeat at offset 6 in C:\xampp\htdocs\blog\test.php on line 11
* in the (?:*) means 0 or more times.
Do you mean \*?

Note that I also added \s* before Theme to match the new line character and spaces

In my Magento application when I try to enable logging in command line using below code
# bin/magento setup:config:set –enable-debug-logging=true
I am getting the error
PHP Fatal error: Declaration of Magenest\SagePay\Helper\Logger::debug($message, array $context = []) must be compatible with Monolog\Logger::debug($message, array $context = []): void in /vendor/magenest/module-sage-pay-basic/Helper/Logger.php on line 49
I have a big log file.
After removing the timestamp of each line, I sort it by cat logfile | sort -u > logfile, so that the logs are clean and organized as

failed to correct PL.ASBF..HHZ.2011.349 because of divided by zero
failed to correct PL.ASBF..HHZ.2011.350 because of divided by zero

I can get the logged items (e.g. PL.HSPB in above example) by
grep -oE " [0-9A-Z]*\.[0-9A-Z]*" logfile | sort -u
However, I also want to known the date info and to make it clearer, I want to remove the intermedia lines. For example,
failed to correct PL.HSPB..HHZ.2011.128 because of Illegal format
failed to correct PL.HSPB..HHZ.2011.129 because of Illegal format
failed to correct PL.HSPB..HHZ.2011.130 because of Illegal format
.
. (lines not shown here)
.
failed to correct PL.HSPB..HHZ.2014.364 because of Illegal format
failed to correct PL.HSPB..HHZ.2014.365 because of Illegal format
after removal becomes
failed to correct PL.HSPB..HHZ.2011.128 because of Illegal format
failed to correct PL.HSPB..HHZ.2014.365 because of Illegal format
i.e., for an item, only the first and last lines are kept (the digits are year and julian day).
Is there any shell command to make this with easy?
Script:
$ cat hhz.py
#!/usr/bin/env python
import sys, re
from collections import OrderedDict
undateds = set()
firsts = OrderedDict()
lasts = OrderedDict()
while True:
line = sys.stdin.readline()
if line == '':
break
line = line.rstrip("\n")
x = re.match("(.*HHZ\.)([0-9][0-9][0-9][0-9]\.[0-9]+)( .*)", line)
if x is None:
continue
before = x.group(1)
during = x.group(2)
after = x.group(3)
undated = re.sub("(.*HHZ\.)[0-9][0-9][0-9][0-9]\.[0-9]+ (.*)", line, before+after)
if not undated in firsts:
firsts[undated] = line
lasts[undated] = line
for undated in firsts:
first = firsts[undated]
last = lasts[undated]
print first
if first != last:
print last
Input:
$ cat hhz.dat

Group things by regexing out the date part. The undated is the uniqified name.
Get first in group by doing an ordered-dict put if not already set.
Get last in group by doing ordered-dict put unconditionally.
Use OrderedDict to preserve input-file ordering (use dict if you don't want that)
Check first != last to avoid printing the same thing twice in case there is only one item in the group
i want to save the output pdf file to public folder my method is
public function qrSVG()
{
$qrCodes = ['4659284fff','465928447','465928447','613271980','484016586','aaaaabbbbbccccc'];
$id = ['201596400-1','201596400-2','201596400-3','831070646','493130428','aaaaabbbb'];
PDF::SetTitle('qrcodes\test');
$i=0;
foreach(array_chunk($qrCodes, 2) as $qrCodee)
{
PDF::AddPage();
$m = 55;
$n = 30;
foreach($qrCodee as $qr)
{
QrCode::size(400);
QrCode::margin(3);
QrCode::errorCorrection('H');
QrCode::encoding('UTF-8');
QrCode::backgroundColor(255,255,255);
QrCode::color(0,0,0);
QrCode::imageTitle($id[$i]);
$svg = QrCode::generate($qr);
PDF::ImageSVG('#'.$svg, $x=$m, $y=$n, $w='100', $h='100', $link='', $align='', $palign='', $border=1, $fitonpage=false);
$i++;
$n = 150;
}
}
ob_clean();
PDF::Output('qrcodes\test.pdf');}
this code generate and open the file put don't save it when i replace the last line in my code with PDF::Output('qrcodes\test.pdf', 'F');
when i put any option with PDF::Output there is an error with F and D options the error when use F is
ErrorException in tcpdf_static.php line 2440:
fopen(): remote host file access not supported, file://qrcodes\test.pdf
and when i replace the last line with
PDF::Output($_SERVER['DOCUMENT_ROOT'] . 'qrcodes\test.pdf', 'F');
the error is
ErrorException in tcpdf.php line 2793:
Undefined property: Elibyy\TCPDF\Pdf::$h
The main reason you're getting the error about remote host file access not supported is because you need to provide the full path in the file name that you provide to the Output() method. Yeah, it's a bit annoying and it catches me out all the time!
I can't comment on the second error you're getting because I cannot get your code to run (missing methods in QrCode class). What version are you using? Also, why are you trying to create an SVG for the QR code and then adding that to the PDF? Instead of taking that approach, I would highly recommend following the approach illustrated in this example:
https://github.com/tecnickcom/TCPDF/blob/master/examples/example_050.php
As you will see in the example, you should create an instance of the TCPDF class and then work with that instance, rather than calling the static methods.
Suppose there is a script A that calls function B, both in Julia.
There are some errors in function B, which cause the script to be stopped at runtime.
Is there a neat way to find out which line is causing the error?
It does not make any sense, to have to put messages like println manually in each line to find out upto which line the code survives, and in which line error happens.
Edit: I am using Linux Red Hat 4.1.2 and Julia version 0.3.6. directly. With no IDE.
Reading the backtrace:
juser#juliabox:~$ cat foo.jl
# line 1 empty comment
foo() = error("This is line 2")
foo() # line 3
juser#juliabox:~$ julia foo.jl
ERROR: This is line 2
in foo at /home/juser/foo.jl:2
in include at ./boot.jl:245
in include_from_node1 at loading.jl:128
in process_options at ./client.jl:285
in _start at ./client.jl:354
while loading /home/juser/foo.jl, in expression starting on line 3
This lines in foo at /home/juser/foo.jl:2 ... while loading /home/juser/foo.jl, in expression starting on line 3 reads as: "there was an error at line 2 in /home/juser/foo.jl file ... while loading /home/juser/foo.jl, in expression starting on line 3"
Looks pretty clear to me!
Edit: /home/juser/foo.jl:2 means; file: /home/juser/foo.jl, line number: 2.
Also you could use #show macro instead of println function for debugging purposes:
julia> println(1 < 5 < 10)
true
julia> #show 1 < 5 < 10
(1<5<10) => true
true
Did an upgrade from 1.5 to 1.6 and now the media browser is not appearing. When I go to a product and try to add some images in the wysiwyg I get the following message when I try to bring it up:
The log reports:
ERR (3): Warning: Missing argument 1 for Mage_Page_Block_Html_Head::addJs() in /var/www/domain.net/app/code/core/Mage/Page/Block/Html/Head.php on line 66
(3): Notice: Undefined variable: name in /var/www/domain.com/app/code/core/Mage/Page/Block/Html/Head.php on line 68
Firebug reports:

I checked all the JS files and they all load. The item /js/ at the end appears to be the problem. Looking in the layout main.xml it appears that it might be /js/prototype/window.js
I tried calling /js/prototype/window.js in the template head which did not work. The log error is for a method that adds the JavaScript to the page.
Here is the code that the log is giving errors messages to:
/**
* Add JavaScript file to HEAD entity
*
* #param string $name
* #param string $params
* #return Mage_Page_Block_Html_Head
*/
public function addJs($name, $params = "")
{
$this->addItem('js', $name, $params);
return $this;
}
I finally tracked down the module that was the root of the issue. I saw this issue with custom modules so I figured some module was causing this.
First I turned off all my modules with this command:
find . -name "*.xml" -print | xargs sed -i 's/true/false/g'
Then I tracked it down to: Fooman Speedster
Hope this helps someone else who runs into this issue.
