Perl6: This is Rakudo Star version 2018.04.1 built on MoarVM version 2018.04.1
implementing Perl 6.c.
Example:
perl6 C:\Users\quest\Desktop\example.pl
# sucess
perl6 "C:\Users\quest\Desktop\яп\Perl 6\web-scraping\request.pl"
# Could not open C:\Users\quest\Desktop\╤П╨┐\Perl 6\web-scraping\request.pl. Failed to open file C:\Users\quest\Desktop\╤П╨┐\Perl 6\web-scraping\request.pl: No such file or directory
Python 3 example:
py "C:\Users\quest\Desktop\яп\py\3\timetest.py"
# sucess
As you have realized, Windows 10 supports UTF-8 for non-Unicode (ie non-UTF-16) apps (according to Wikipedia, this feature was added with build 17035, released in April 2018, and is still marked 'beta'). This makes Rakudo happy.
However, not respecting your locale while Python manages to do so still seems worthy of a bug report to me.

[Solved (at bottom). installed quartz and re-installed with x11 via brew then restarted machine.]
I'm learning Ocaml and am going through these documentations pages and need to install some modules (graphics).
I'm missing a Graphics module in Ocaml. After trying to load it on toplevel (the REPL right?) with:
$ ocaml
OCaml version blahblah
# #load "graphics.cma";;
# open Graphics;;
I get the error message:
Cannot find file graphics.cma.
So I wander over to this question and after not finding the file with the command:
ls `ocamlc -where`/graphics*`
I read that this means that:
Graphics is not installed and you have to reinstall OCaml compiler
enabling Graphics.
Does this mean I have to recompile Ocaml every time I need a new module? I'm not sure what he meant by that.
Then, I tried to install Graphics with: opam install graphics.
I got this error:
This package relies on external (system) dependencies that may be missing. `opam depext lablgl.1.05' may help you find the correct installation for your system.
So I did opam depext lablgl.1.05
After this, I tried opam install graphics again, but it failed with this error:
#=== ERROR while installing graphics.1.0 ======================================#

This error says Cannot find file graphics.cma which brings me back to this question and what the steps are to get graphics.cma (and other modules as I might need them).
I though opam was a package manager for ocaml (this install modules right?)
EDIT:
I did brew info ocaml and I did install with x11 so I though this meant I should have it...

EDIT 2:
Running
brew install Caskroom/cask/xquartz
brew reinstall ocaml --with-x11
Allowed me to compile, but running gave me this fatal exception. Seems to be an X11 thing?
Fatal error: exception Graphics.Graphic_failure("Cannot open display ")
Solved
So I think the two steps that were necessary were to make sure ocaml was installed with X11. Note that `brew info ocaml` seemed to give wrong information (said it was installed with X11 but reinstall was necessary). On OSX, I also needed to install quarts.
brew install Caskroom/cask/xquartz
brew reinstall ocaml --with-x11
After this I COULD compile, but got an error on execution. This was simply solved by restarting which I read was necessary after installation of xquartz.
After that I could run fine.
The graphics module is an optional part of the base OCaml install, not an external module. This explains why you can't install it using OPAM. The OPAM module that you show is only testing whether it is installed in the current OCaml system. It can't (and hence doesn't try to) install graphics as a separate module.
For this reason, installing graphics (when it's not already installed) is unusually tricky. There's no need to recompile OCaml for installing most (if not all) other modules.
For what it's worth, I am running macOS 10.12.4, and I used "opam switch" to switch my OCaml system to the 4.03.0 release. In the resulting environment, the Graphics module is installed, and I have no trouble running the examples at the website you mention. (For the first, I see concentric red and yellow circles, for example.)
You might try doing "opam switch" to switch to a recent version of the compiler, and see if this gets things going for you. In the past I have had trouble getting Graphics to work, but it is working great for me now.
I have much trouble to have a code to convert pdf file to png on python 3.6, windows 10.
I know what you are going to say : google it !
But barely everything I've found was on python 2.7. And some packages haven't been updated.
What I've seen so far it's that the best way to do it is using Wand, right ? (I have installed ImageMagick before )
from wand.image import Image
# Converting first page into JPG
with Image(filename='0.pdf') as img:
img.save(filename="/temp.jpg")
# Resizing this image
Here was my second error :
wand.exceptions.DelegateError: PDFDelegateFailed
`The system cannot find the file specified.' # error/pdf.c/ReadPDFImage/809
So i read i need ghostscript. I installed it. But the package is for python 2.7 and it doesn't work. I found python3-ghostscript 0.5.0. https://pypi.python.org/pypi/python3-ghostscript/0.5.0
New error :
RuntimeError: Can not find Ghostscript DLL in registry
So here I needed to install Ghostscript 9 :
https://www.ghostscript.com/download/gsdnld.html
First of all it's not a GPL license ... That's not even a package but a program. I don't know how I can use it in my futures python codes...
and there is still an error :
RuntimeError: Can not find Ghostscript DLL in registry
and i can't find anything for it.
Ghostscript is licensed under the AGPL, the licence can be found in /Program Files (x86)/gs/gs9.21/doc if you want sources then they are available from the Ghostscript Git repository. Note I'm assuming you are running on Windows since you refer to the Registry.
If you install the prebuilt binary then it will create an entry in the Windows Registry, I assume that's what your Python code is looking for but I can't be sure. You should make sure you install the correct word size (32 or 64) version required by Python, if it cares.
You can, of course, simply run Ghostscript to render a PDF file and produce PNG output.
gswin32c -sDEVICE=png16m -sOutputFile=out%d.png input.pdf
This will create one file per page of the input PDF file, use gswin64c for the 64-bit version...
You can alter the resolution of the output with the -r switch, eg -r300
I presume you can simply fork a process from Python. Otherwise you'll have to get someone to tell you what the Python script is looking for in the Registry. Perhaps its looking for a specific version of Ghostscript, or the 32-bit version or something.
As mention in Orafce Install.orafunc:
..install Orafce functions in the database, either run the orafce.sql script using the pgAdmin SQL tool..
I tried running the orafce--3.0.sql in pgAdmin sql editor. This give me error
ERROR: could not access file "MODULE_PATHNAME": No such file or directory.
What do you mean by module path?
Installed program:
strawberry perl with DBD::Oracle
postgresql 9.3
pgAdmin III
Not fully installed:
ora2pg
I tried installing ora2pg...with a problem.
H:\PostgreSQL\ora2pg-12.1>perl makefile.pl

Suggested Solution:
I downloaded a copy of orafce from okbob github
Unzip the file to folder D:/Postgresql/orafce-master
I copy only the following files
orafce--unpackaged--3.0.6.sql
orafce--3.0.6.sql
orafce.control
to folder C:\Program Files\PostgreSQL\9.3\share\extension
Then I try running this command in pgAdmin III sql tools.
CREATE EXTENSION orafce;
I received this Warning and Error.
[WARNING ] CREATE EXTENSION orafce
ERROR: syntax error in file "C:/Program Files/PostgreSQL/9.3/share/extension/orafce.control" line 1, near end of line
I checked orafce.control content. It has this config.
# intarray extension
comment = 'Functions and operators that emulate a subset of functions and packages from the Oracle RDBMS'
default_version = '3.0.6'
module_pathname = '$libdir/orafunc'
relocatable = false`
I can't pass to this wall. What seems the problem?
So, you are working with source raw files. You should to compile these files first - and later you can use it. It is relative simply on Unix like platforms, where C compiler is usually available, and pretty hard on MS Windows, where you have to install C compiler first.
I afraid so we lost pgFoundry archive, where was orafce precompiled and packed.
Almost all Linux distributions support orafce directly - and you can install it without compilation from repositories.
see http://wiki.postgresql.org/wiki/Building_and_Installing_PostgreSQL_Extension_Modules
$libdir is symbol, that is used for PostgreSQL extensions directory. It can be different for any platform - and it is replaced inside compilation stage by actual value. MODULE_PATHNAME has similar meaning. In compilation stage is replaced by valid actual path to library with compiled code.
I am sorry - we don't provide a compiled files - mainly due high risk for MS Windows. We have no forces, and tools to maintain all Win safely. In this moment, you can:
try to contact someone who use orafce for windows for backup of orafce installers
try to compile this extension by self (Microsoft Visual Studio Express edition is free and downloadable on internet).
other possibility is migrate database server to Linux - almost all database maintenance and usage is more simply and more robust there (due missing viruses, antiviruses and less resource requests). The Linux is primary platform for Oracle too.

I've read some apps in Asterisk 10 still use timers from dahdi_dummy. But it won't build - make ignores dahdi_dummy module:
root#ster:/usr/src/dahdi-linux-complete-2.6.0+2.6.0# find ./ -name '*dummy*'
./tools/menuselect/contrib/Makefile-dummy
./tools/menuselect/contrib/menuselect-dummy
./linux/drivers/dahdi/dahdi_dummy.c
dahdi show status in cli shows nothing. Really i will not use digium cards, so i probably need only dahdi_dummy.
# lsmod | grep dahdi
dahdi_transcode 13001 1 wctc4xxp
dahdi_voicebus 45931 2 wcte12xp,wctdm24xxp
dahdi 191058 11 wct4xxp,dahdi_voicebus,wcte12xp,wct1xxp,wcte11xp,wctdm24xxp,wcfxo,wctdm,wcb4xxp,dahdi_transcode,xpp
crc_ccitt 12347 2 dahdi,wctdm24xxp
So, may be i don't need that module anymore? And why it won't compile?
Thanks.
You do not need dahdi_dummy anymore. It has not been required since DAHDI-Linux 2.3.0. The core of DAHDI is now able to use the kernel timers automatically if no telephony hardware is installed.
The reason it won't compile in 2.6.0 was due to an error that was fixed in 2.6.0-rc1. The interface between the core of DAHDI and the board drivers changed but dahdi_dummy was not updated as well. More information is available on the Asterisk issue tracker in issue DAHLIN-274.
I am working with LaTeX on Vista using TeXnicCenter 2.0 Alpha 3 (build 1118) having installed MiKTeX 2.8. I want to use code highlighting for Objective-C and read here that the minted package is great.
I installed Python 2.7 and pygmentize as told in the minted documentation. I also set the compiler option -shell-escape in TeXnicCenter. The compiler finds the pygmentize script but the following error occurs.
File "C:\Python27\Scripts\pygmentize.exe", line 1 SyntaxError: Non-ASCII character '\x90' in file C:\Python27\Scripts\pygmentize.exe on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details! LaTeX Error: File `Test.out.pyg' not found. Type X to quit or to proceed, or enter new name. (Default extension: out.pyg) Enter file name: ! Emergency stop.
I cannot figure out how to fix the problem. I tried saving the tex file as ANSI or UTF-8.
The only additions I made to the tex file are the package include
\usepackage{minted}
and this simple example from the minted documentation.
\mint{python}|import this|
The minted documentation is outdated: newer versions of Pygments apparently include a Windows executable pygmentize.exe (unfortunately, their Trac is currently offline so I can’t look up the relevant revision which changed that).
This means that the fix mentioned in the documentation should be redundant. Therefore, try the following steps:
Remove the pygmentize.cmd script entirely (best not delete it yet – just rename it). Try if minted now works.
If that doesn’s work, put the following into the pygmentize.cmd:
#echo off
set PYTHONPATH=C:\Python27
%PYTHONPATH%\Scripts\pygmentize.exe %*
i.e. don’t invoke the *.exe file via the Python interpreter.
Unfortunately, I can’t test this now since I don’t have Windows here. But one of the options should work.
