FR35 URL through scripts

URL loads script file automatically

Is requested the capability of running CEL or CELX scripts using URLs.

Description:

Actually it is not possible to define an URL with multiview. So it is not possible to click over an Hyperlink in an HTML document and open Celestia with 3-4 (or even more) different views.

I was asking me if should be very difficult to implement a different kind of Celestia URL. Instead of a URL in semi-binary format like the following:

cel://Follow/Sol:Mercury/2003-08-01T13:15:51.15898?

x=AMBAWebCUuPkDA&

y=Cpuhlugs9C4e&

z=VQr63TfoNIgc&

ow=0.863894&

ox=0.258879&

oy=-0.420347&

oz=-0.099883&

select=HD%2075318&

fov=45.000000&

ts=0.000000&

rf=40375&

lm=1244162

a simple reference to a CEL script.

Using URL CEL script commands should be somewhat easy to operate with Celestia URLs. The HTML code should be something like this:

<a href="http://www.myweb.com/myfolder/myURLScript.cel">
CEL-URL example
</a>

The script file called in the url is saved in a web site.

The multiview script commands implementation is described in FR37.

Obviously the current URL capture mechanism is very very handy. It is not suitable that Users creates a script from scratch to configure all the things. Instead Celestia should create a script with all the current view settings, included.

So instead of an URL in Semi-Binary format, a plain text script file should be generated and prompted for saving by Celestia. Something like the Don’s standard startup CEL Script plus a Gotolonglat and a Time script commands.

Another useful feature should be the capability of running a sob script called from the main script.

So the final script called by "the URL should be something like this:

#set the subscripts folder

SetPath {name "http://www.myweb.com/myfolder/URL1"}

#call the sub script for initial settings

CallScript {name "../generalscripts/Initial.cel"}

#call the sub script for video splitting

CallScript {name "../generalscripts/panelsplit9.cel"}

#set active pane

SelectPane {ID 1}

#call sub script.

CallScript {name "pane1.cel"}

#set active pane

SelectPane {ID 2}

#call sub script.

CallScript {name "pane2.cel"}

#etc.

...

For instance one of the sub scripts captured directly by Celestia (see FR34) should be:

#pane 1 initial settings and preferences

select {object "Mars"}

time {jd 2452862.89542}

gotolonglat {
   time 5
   distance 4
   longitude -122
   latitude 47
}

#set final preferences

...

#etc

...

The porting of the URL cel scripts in celx Lua script format should be surely easy.

Required/Suggested:

FR34 Script recording.
