Which is the best way of opening a PDF and HTML local files from Pharo

Hi,

I'm trying to open some local files from Pharo. They're in PDF and HTML
format. I thought that I could use WebBrowser, so it can delegate to the
browser opening the files, without any other requirement, but is not
working. There is a better way to open such files from several platforms?

Cheers,

Offray

Hi Offray,

You may want to do it with a hierarchy of classes, one for each host, to
handle concretely the PDF and HTML OS viewer you want to use, and
another class to handle it uniformly.

For example MyOperation>>openPdf: aFile
then it will delegate to LinuxOperation/WindowsOperation/MacOperation
depending on the host running the VM.

That way you could add up more operation when needed.

But likely there is already something like that in the system but I
can't see.

Oh, you can add your extension to the OSPlateform hierarchy.

So one your extensions added in the hierarchy, your code will use it
with an uniform:

OSPlateforme current openPdf: 'grafoscopio.pdf'

Thanks Hilaire.

I was thinking in something that depend on OSProcess and invoke xdg-open
on Linux, for example, but is not working neither.

OSProcess command: 'xdg-open ', pdfPathString

doesn't open the PDF file :-/.

Hi Offray,

Which version of Pharo are you running? My understanding is that
Pharo5 & 6 use OSSubprocess, not OSProcess.

I'm using xdg-open to open pdf files on linux (Arch):

| proc |

proc := OSSUnixSubprocess new.
proc
command: 'xdg-open';
arguments: (Array with: url).
proc run.
UIManager inform: 'Opened: ', url.

url is the path to the file in this case.

You can check the exit status with:

proc exitStatusInterpreter

e.g.:

proc exitStatusInterpreter isSuccess

Cheers,
Alistair

Hi Alistair,

Unix process is making the task properly. Now I wonder how I can load
the proper OS-Windows, OS-Unix or OS-Mac in Monticello, so the
Grafoscopio package loads only the requirements for making this work
accordingly to the platform where is running.

Cheers,

Hi Offray,

I tried "OSProcess command: 'xdg-open ', pdfPathString" in Pharo, and it works
for me. Maybe check to be sure that pdfPathString is right?

if you don't control pdfPathStrig you will also need to escape this string. I don't know if Pharo/OSProcess has support for the necessary escaping. E.g. 'foo.pdf; rm -rf /' as input should not lead to the removal of your system. :)

Unfortunately this is beyond my experience with configuration
management. However I would have thought there is a good argument that
all platforms should be loaded so that the image remains platform
independent.
