how to customize login page and site label
I can't find any docs on how to change the site label and login pages
in the current 9.13. Changes made in the translation pages don't seem
to do anything.
Thanks.

did that. even switched browsers, it's definitely not. I'm thinking that
'unable to merge language resource "en" ' is to blame...

Clear the browser cache. I have the same issue when I modify mine.
or try a different computer.
If it is loaded then it is there.

Hey Dan,
try the following:
{
"NAME" : "English",
"APP":{
"NAME" : "XYZ APP"
}
}
In translations/en.json

So, for what it's worth, I converted the fonts to WOFF and OTF, in addition
to TTF, and put the directives for all of the formats into the resources and
CSS files. It seems to pull in the WOFF-formatted fonts just fine - not
sure if it's because I'm still missing the correct MIME type for TTF (I'm
using application/x-font-TrueType), or if Chrome doesn't like TTF or my
version of TTF. But, for whatever reason, it's working with WOFF. Probably
a better choice, anyway :-).

Nope, no specific errors. I'm not seeing any invalid JSON or CSS messages
in the logs, and nothing in the browser. Here's what I've done:
- Placed font files (TTF format) in my extension's "resources/" directory
- Added the entries to the guac-manifest.json file in the resources section
for the font files.
- Created a new CSS file with the @font-face directives to load the fonts.
I'm using the "app/ext/guacamole-branding-nick/resources/Font.ttf" path in
the url() area, same as the custom logo (which works fine).
- Add the new CSS file to the correct area in the guac-manifest.json file.
- Add directives to my other CSS file to change the font for things like the
header, login page, etc.
When I load the page, the font doesn't load at all, and if I open up the
Google Chrome Inspector panel, I see:
- CSS file is loaded correctly and I can find the @font-face directives for
my new font.
- CSS file correctly displays my changes for places where I've specified
font-family with my custom font.
- The font files do *not* show up in the
sources/app/ext/guacamole-branding-nick/resources folder in the inspector
panel.
- If I point my browser directly at the font file with the full URL to the
font, it downloads correctly.
So, the font is in the right path, the CSS is getting loaded, but, for one
reason or another, the font is not being used on the page. I'm not sure if
this is something with the MIME type I'm using not being recognized by the
browser or if there's something else I'm missing?
Thanks,
Nick

Hey Nick,
No, Guacamole doesn't apply any limitations to the MIME types of resources
exposed via extensions. It's on the author of the extension to determine
the correct MIME type, but Guacamole will simply pass that through.
Are you seeing any specific errors from the browser when attempting to load
the resource?

Side (but related) question - I'm trying to load a custom font with the
resources section, and I think I'm not getting the MIME type quite right.
Is there a limit to the types of files Guacamole will load in this resource
section, or do I just need the correct type of the file? I've tried several
different variations of application/font-* and none of them have allowed
Chrome to actually load the resource.
Thanks - Nick

Re: how to customize login page and site label

I'm not getting that. I see the xyz module is loaded, but it's not sending
that to the browser and there's the "en" issue from above...
my guac-manifest.json again:
{
"guacamoleVersion" : "*",
"name" : "xyz",
"namespace" : "xyz",
"translations" : [
"translations/en.json"
]
}
can you send me a copy of your extension? I'll see if it loads in mind,
maybe track down my error?

Re: how to customize login page and site label
Posted by dan <da...@gmail.com>.
it's the resource line. something is weird with it. If I remove it I get
my text in the login page (but no image).
jar attached (added zip ext so it will send)
This produces a text theme, but no image (I suspect the path in the css is
funky...)
I cannot put the resource line in else the module fails to load.

this one, I think you linked it. It's your first post on the page:

I noticed a difference a number of posts down.
It's working now though, thanks for all the help!

The manual correctly states that the "resources" property is an object, and
the example provided a little bit below the table of properties
demonstrates it as such:

The string "Theming Extension" referred to by Erik is actually the name of
the extension as declared in guac-manifest.json. That much looks correct
here, as your extension is listed by name as loaded.
The error regarding the failure to merge the language resource refers to
your translation JSON, and is preventing your extension from loading fully.
Looking at what you posted previously:
{
"APP" : {
"NAME" : "XYZ APP",
}
}
You have a trailing trailing comma after "XYZ APP", which JSON does not
allow. If you remove that comma, rebuild your extension, and restart
Tomcat, I expect that error will disappear.

in the root where guac-manifest.json is located.
zip -r xyz.jar *
move that to

which is linked to
/etc/guacamole
reload tomcat
INFO o.a.g.extension.ExtensionModule - Extension "xyz" loaded.
but no change to the app name.

For all current releases of Guacamole, /etc/guacamole will not be used
unless you have taken explicit steps to override the default search
locations for GUACAMOLE_HOME. This has changed recently, but that change is
not yet in a release:
https://issues.apache.org/jira/browse/GUACAMOLE-335
The default search locations, in order of priority, are defined in the
manual:
http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#guacamole-home
The easiest option is to simply create a ".guacamole" directory within the
home directory of the tomcat user. Which user that actually is will depend
on how you've installed Tomcat, but assuming you installed Tomcat via your
distribution's packages, there will likely be a user defined specifically
for that service, and the home directory will be visible within /etc/passwd.
Once you believe you have your extension in the right location, be sure to
check the Tomcat logs if things still aren't working. Guacamole will log
its attempts to load extensions, including any failures due to the
extension not following the correct format. If those messages don't provide
enough information, you can also enable debug-level logging:

Re: how to customize login page and site label

Mike, can you offer a little help?
I'm reading this that I need to create a guac-manifest.json that
contains a couple minimal items. zip that and rename to .jar, put in
/etc/guacamole/extensions/, restart guac
Does that sound right?
If so, I don't have a clue what to do for changing the page name. I
see in the page source of the rendered page that the title is set, but
when I look into those files the text isn't there.
<title ng-bind="page.title | translate" class="ng-binding">Apache
Guacamole</title>
thanks

On the contrary!
Please see the Guacamole extension format:
http://guacamole.incubator.apache.org/doc/gug/guacamole-ext.html#ext-file-format
All user-visible text within Guacamole has a corresponding translation
string, which can be overridden by providing a new string for that
same translation key within your extension. The content of the various
HTML templates can also be overridden/augmented using
specially-formatted HTML snippets.
It shouldn't be necessary to patch the web application source, unless
the intent is to fork the source to produce your own application which
you will maintain independently of mainline. The idea behind the
extension subsystem is to allow such changes to Guacamole to remain
stable and independent.

That's fine - we're happy to help you figure out how to accomplish this.
If you have the source, then you need to edit it and then rebuild it. This
is pretty simple, just requires that you have Maven and JDK installed on
your system, so after you make the changes to the source you go to the
top-level directory and type "mvn package" which rebuilds everything. Then
you can grab the resulting WAR file from the guacamole/target directory and
deploy that. You can find more detailed instructions on this process in the
manual:
http://guacamole.incubator.apache.org/doc/gug/installing-guacamole.html#building-guacamole-client

In my experience, making sure that the changes you make are in the WAR file
is the only reliable way to ensure that the web application always contains
your changes and that those changes are never overwritten with other files.
This requires a little bit of extra work to get the source, Maven, and JDK,
and rebuild everything, but it's worth it to have a WAR file that contains
your changes and that you can redeploy and deploy to multiple systems
without having to make the same changes over and over again.
This is my opinion, based purely on my past experiences deploying web
applications in Java servers, so do what works for you - just beware that if
your guacamole.war file gets touched by some process (a backup, another
admin, etc.), or you go to upgrade to the next version that comes out, you
risk overwriting those changes, and, at the very least, having to copy the
changes back over every time the web application gets redeployed.

You can do this, and it does work to try things out, but I recommend against
this as a long-term solution. There are specific circumstances that will
trigger Tomcat to re-deploy the web application from the WAR file, and if
you make the changes only in the deployed web application
(webapps/guacamole/), and not in the WAR file, you will lose your changes.

Yes, I understand what you're trying to accomplish - I'm asking you what
files you tried changing that you said did not work, and how you tested it -
did you try changing certain files in the deployed version of the Guacamole
