[idea] ni2http sorted services list

[jpuigs]

would it be possible , in ni2http --list option, to get the services list sorted by subchannel ID ?

Better would be sorted by start CU.

.. or by name.....
In order to suit everybody's wishes,:
-- list -> current situation
-- list i -> sorted by Subch ID
-- list c -> sorted by start CU
-- list n -> sorted by name
-- list s -> sorted by service ID
....

The code is open source. You could basically do it yourself. Even I did it (and I am not a programmer, just a normal user)

Change https://github.com/piratfm/eti-tools/blob/master/wfficproc.c by separating the fields by a semicolon (which I hope it's not used for service labels) and remove unnecessary text and spaces and numbers, for instance start=%3d to ;%d; to have a number, not a text.

Then output the ni2http --list to a file by piping it with ni2http --list 2> file.txt (Remark: > does not work as this is the stderr output), delete the 1st row and then process it with awk and sort.

I can post the detailled solution later, but I will not change the code here.

And you can change line 186 in https://github.com/piratfm/eti-tools/blob/master/wfficproc.c#L186

from
int i = 0;
to
int i = 1;

that the 1st service begins with 1, not with 0.

0 : BBC Radio 1 (0xc221) Pri subch= 1 start= 0 CUs= 96 PL=uep 3 bitrate=128

Of course you have to re-compile it by make in the eti-tools folder.

line 186 was the 1st thing I changed :-)
I tried to sort inside wffic.c , but my knownledge of c++ is very very limited, and I didn't success.
Each line has 3 elements, Label name, sid, and "rest". so it had to be sorted all of them.
I had no problems with sid and "rest", but label name was problematic, and I don't know why.
I used classic sort procedure , compare one element with next one, and if it's bigger the first one, then swap with second one.
If you could post code, it'll be good.

output.txt

$ cat output.txt | sed 's/Pri subch=\|start=\|CUs=\|bitrate=\|PL=//g' > output_new.txt

sort by label:
$ cat ./output_new.txt | sed '1d' | sort -t ";" -k2

sort by SId:
$ cat ./output_new.txt | sed '1d' | sort -t ";" -k3

sort by subch (note, you have to specify it as number)
$ cat ./output_new.txt | sed '1d' | sort -t ";" -nk4

sort by start CU (specified as number)
$ cat ./output_new.txt | sed '1d' | sort -t ";" -nk5

sort by used CUs (specified as number)
$ cat ./output_new.txt | sed '1d' | sort -t ";" -nk6

sort by protection level
$ cat ./output_new.txt | sed '1d' | sort -t ";" -k7

sort by bitrate (as number)
$ cat ./output_new.txt | sed '1d' | sort -t ";" -nk8

sort by DAB/DAB+
$ cat ./output_new.txt | sed '1d' | sort -t ";" -k9

wfficproc.zip

You could then save this as alias so that you don't need to re-type them.

Thank's. I'll try.
