wwtdatatool preview
¶
The preview
command allows you to preview a draft WTML file by opening it
up in a browser window with the WWT webclient or the WWT research app. The
file and its associated data sets are made accessible to the webclient through
an embedded HTTP server.
Usage¶
wwtdatatool preview
[--research] [-r]
[-b BROWSER] [--browser BROWSER]
[--appurl URL]
{WTML}
The WTML
argument is the path of a WTML file. This may be an
index_rel.wtml
file, containing relative URLs, or a regular WTML file
containing only absolute URLs.
If the -r
or --research
option is supplied, the file is previewed using
the WWT research app. By default, the WWT webclient is used.
The -b
or --browser
option specifies which web browser to use, using an
identifier as understood by the Python “webbrowser” module. Typical choices
might be firefox
, safari
, or google-chrome
. If unspecified, a
sensible default will be used.
The --appurl
option can be used to override the base URL for the preview app
that will be used. This can be helpful when developing new features in one of
these apps.
Example¶
After tiling an image with toasty into a directory named tiled
, preview
the tiled data:
wwtdatatool preview tiled/index_rel.wtml
Details¶
This command runs the same kind of local HTTP server as described in the documentation for the wwtdatatool serve command.
