cli-downloader (qt5 c++ and baconized )

[bigbass]

Hello

I needed a way to add downloads to a qt browser / viewer
that am working on I wanted it to be useful to add to any Qt code
so here is a standalone cli-downloader
that will allow parallel downloads

it took quite awhile to remove the class code
and port it to bacon and modify some parts for bacon





just leave a space between links
here is an example with a .html , .bac ,.tar.gz


Sept 10 2022 will keep the updated source and documentation here

sourceforge.net/p/bacon-qt5/wiki/cli-downloader/

Hi Joe

installed libqt5websockets5

works here on rpi4

would it be possible to add -o output file to/dir/file*

BR
Alex

[bigbass]

Hello Alex

thanks for the feed back for the RPI4

I will add libqt5websockets5 to the dependency list

your suggestion about the -o target directory is a good one!
I will see what can be done to make it happen
Qt has its own special way of doing things so will need to investigate

Joe

Dear Joe,

Thanks. It works very nicely in the Pi. On Mint, however, I get a compile error:


In file included from qt-downloader.bac.h:2:0,
                from qt-downloader.bac.c:2:
qt-downloader.bac.generic.h:3:10: fatal error: QtCore/QDebug: No such file or directory
#include <QtCore/QDebug>
         ^~~~~~~~~~~~~~~
compilation terminated.
make: *** [qt-downloader.bac.o] Error 1


Do you have any idea why? I thought I had all the QT5 bits already installed...and your nano browser compiles and works fine on both my platforms.

With kind regards,
vovchik

[bigbass]

hello vovchik

I added to the x86 PRAGMA line
try to copy all again

before it was all one line with the -fPIC at the end
I added the path to QtCore also

maybe if this still doesnt work copy the last working PRAGMA line
and PRAGMA LDFLAGS that would compile?
Joe

[vovchik]

Dear Joe,

Thanks. It now works on Mint. I had to change one sub with FORMAT to remove a warning (adding fmt$):


'--------------------------------------------
SUB  downloadFinished(QNetworkReply *reply)
'--------------------------------------------
'PRINT "(4)"
LOCAL url TYPE QUrl
LOCAL fmt$ TYPE STRING
url = reply->url()
IF (reply->error()) THEN

COLOR RESET
ELSE
IF (isHttpRedirect(reply)) THEN
COLOR FG TO INTENSE BLUE
fmt$ = "%s%s\n"
EPRINT "Request was redirected.\n", stderr FORMAT fmt$
COLOR RESET
  ELSE
'--- use a fincounter to see how many urls finshed and downloaded
QString filename = saveFileName(url)
IF (saveToDisk(filename, reply)) THEN
COLOR FG TO INTENSE YELLOW
PRINT "Download of  ", url.toEncoded().constData()  , "  succeeded!"   FORMAT "%s%s%s\n"
PRINT "saved as " , PRINTABLE(filename) FORMAT "%s%s\n"
INCR fincounter

END IF
END IF
END IF



IF (dlcounter == fincounter ) THEN
COLOR FG TO GREEN

COLOR RESET
END
END IF



END SUB

Hello Alex and vovchik

I looked at the Qt way of doing -options
and it all seemed like overkill for only one option
so I just invented another way to do it

just note and look at the screen shot if there are any questions


./cli-downloader -o ~/Downloads/ url url
'---must have trailing slash when using the ~/target_dir/ !

But anyway here it is Alex what you suggested an -o /dir/ option

hi joe

getting this on rpi4

but it works

Dear Alex (and Joe),

Me too. I get that in Pi...

[bigbass]

Hello Alex and vovchik


first thanks for the detailed error
I was able to force my pi3 to fail
with -Wformat=1 then solve the problem
or else it will keep coming up
thanks for your bacon solution too


Alex you are expecting curl with only 280 lines of code
luckily was able to make it happen anyway for this demo with a forced user agent hack

all your suggestions Alex and vovchik will make things better thanks!

prestep if its not there

Dear Joe,

Thanks for the update. I am now getting this identical error on Pi and Mint (runtime):


ASSERT failure in QList<T>::at: "index out of range", file /usr/include/x86_64-linux-gnu/qt5/QtCore/qlist.h, line 541
ERROR: signal ABORT received - internal error. Try to compile the program with TRAP LOCAL to find the cause.
ERROR: signal for SEGMENTATION FAULT received - memory invalid or array out of bounds? Try to compile the program with TRAP LOCAL to find the cause.


Is an empty list causing the problem?

With kind regards,

[bigbass]

Hello vovchik

working on it
yes probably I have to clean the list somehow

I added your fix and used a regx
args.replaceInStrings(QRegExp("^\\s+"),"")


maybe...? it works now

Joe

Hi Joe

that worked from the file in a certain dir

in end put the cli into /usr/bin
