[Freeswitch-dev] INFO: Channel variables

[Michael Collins]

Guys,

 

I made a list by grepping and perling around in the source.

 

grep -Pr "c(.)(\s+)switch_channel_set_variable\(channel, \"" * | grep -v
"Binary" > /tmp/chan_vars.tmp

 

This gave me a massive list of all filenames and occurrences of
"switch_channel_set_variable" with a channel variable explicitly named
in quotes.

 

I then filtered out stuff with svn in the source filename and then
create a tab-separated list of chan variables and source filenames.
Finally, I distilled that list with this script:

 

perl -n -e 'm/(\w+)\t(.*)/;next if (exists($seen{$1}));print $1 . "\t" .
$2 . "\n";$seen{$1}=$2;' /tmp/chan_vars3.tmp

 

This yielded a nice list of variables.  Let me know what you think about
using this as the base list for channel variables on the wiki:
