a situation where I'd like to have subsets of options based on some
other option setting.
For example, in gr-dvbt2, I have an option setting for the version of
the specification. Based on that option, I want to have the preamble
options be T2 SISO or T2 MISO for version 1.1.1, or T2 SISO, T2 MISO,
T2-Lite SISO or T2-Lite MISO for version 1.3.1.
I've come up with a method, but it's super kludgy since it uses
two variables for the same option. In this case, preamble1 and
preamble2.
<param>
<name>Specification Version</name>
<key>version</key>
<type>enum</type>
<option>
<name>1.1.1</name>
<key>VERSION_111</key>
<opt>val:dvbt2.VERSION_111</opt>
<opt>hide_111:</opt>
<opt>hide_131:all</opt>
</option>
<option>
<name>1.3.1</name>
<key>VERSION_131</key>
<opt>val:dvbt2.VERSION_131</opt>
<opt>hide_111:all</opt>
<opt>hide_131:</opt>
</option>
</param>
<param>
<name>Preamble</name>
<key>preamble1</key>
<type>enum</type>
<hide>$version.hide_111</hide>
<option>
<name>T2 SISO</name>
<key>PREAMBLE_T2_SISO</key>
<opt>val:dvbt2.PREAMBLE_T2_SISO</opt>
</option>
<option>
<name>T2 MISO</name>
<key>PREAMBLE_T2_MISO</key>
<opt>val:dvbt2.PREAMBLE_T2_MISO</opt>
</option>
</param>
<param>
<name>Preamble</name>
<key>preamble2</key>
<type>enum</type>
<hide>$version.hide_131</hide>
<option>
<name>T2 SISO</name>
<key>PREAMBLE_T2_SISO</key>
<opt>val:dvbt2.PREAMBLE_T2_SISO</opt>
</option>
<option>
<name>T2 MISO</name>
<key>PREAMBLE_T2_MISO</key>
<opt>val:dvbt2.PREAMBLE_T2_MISO</opt>
</option>
<option>
<name>T2-Lite SISO</name>
<key>PREAMBLE_T2_LITE_SISO</key>
<opt>val:dvbt2.PREAMBLE_T2_LITE_SISO</opt>
</option>
<option>
<name>T2-Lite MISO</name>
<key>PREAMBLE_T2_LITE_MISO</key>
<opt>val:dvbt2.PREAMBLE_T2_LITE_MISO</opt>
</option>
</param>
Does anyone know of a more elegant method? I've tried some
Cheetah stuff, but that never seems to work for me at all.
best regards,
