zenity's option to render html does not work

[sudodus]

Zenity was updated a few days ago. Until then there was a bug with --checkbox, which is fixed now :-) But another bug was introduced: zenity's option to render html does not work. A similar bug was squashed in OpenSuse last year, and is still there in Fedora and Centos. But --html works in all versions of the Ubuntu flavours from 12.04 LTS 'Precise' to 15,04 'Vivid', and worked in 'Wily' until this last update of/to zenity 3.16.3.

The error output states:

"This option is not available. Please see --help for all possible usages."

The bug that was squashed last year was fixed in OpenSuse by compiling with WebKit. Maybe that works also now, maybe another tool is necessary now to add capability for html with the option --html.

Arx Cruz knows which tool to use:

"The --html is only available when you compile with webkit > 2.8.1 and the library is webkit2gtk. See https://bugzilla.gnome.org/show_bug.cgi?id=749798

If the new zenity wasn't built with support to this, you won't see the --html option."

You can run the following bash shell-script to test if it works or not.
-----
#!/bin/bash

echo "<h1>HTML headline</h1>
Hello World" | zenity --text-info --html --filename=/dev/stdin \
--width=$(($wadd+640)) --height=$(($hadd+400)) \
--title "$btitle" \
--ok-label="Go" --cancel-label="Quit" \
--checkbox="Check this box if you are ready to go"
-----
It should create a window similar to that in the attached file 'correct-rendering-html-precise.png'

Hello,

I was wondering if the name of the option could have changed, or replaced by another action, so I did a check on the info file "text.page" in /usr/share/help/C/zenity for this version of the zenity-common package, and the "--html" is still what is supposed to be used for this case.

Arx Cruz told me:
--
The --html is only available when you compile with webkit > 2.8.1 and the library is webkit2gtk. See https://bugzilla.gnome.org/show_bug.cgi?id=749798

If the new zenity wasn't built with support to this, you won't see the --html option.

So please re-compile zenity with such a webkit version :-)

[sudodus (nio-wiklund)]

In wily zenity does not even accept the option --html

[victor00000 (vict1971)]

Yes http://

L~$
L~$ echo "<img src=\"http://localhost/1.png\"/>" | strace -f zenity --text-info --html --filename=/dev/stdin 2>&1 | grep "1\.png"
read(7, "<img src=\"http://localhost/1.png"..., 4096) = 36
[pid 31543] send(15, "GET /1.png HTTP/1.1\r\nHost: local"..., 169, MSG_NOSIGNAL) = 169
L~$

I found it in the repos, upgraded and yes, zenity works with --html again in Wily :-)
