Sorry, I've been feeling under the weather since yesterday. Anyways:
With vd in your path
printf %"d\n" 1 2 3 4 5 | vd
then
1. Shift+C: brings you to the 'columns sheet'
2. s: selects the 'text' column
3. g%: switches the 'text' column to float type
4. q: brings you back to the row sheet
5. z+: asks you for an aggregator name, type 'avg' and ENTER
You get the mean on the status line.
Now, if you configure Visidata with this in a '.visidatarc' file where vd
can find it:
#--------------------------------------------------------------------------
import sys
sys.path.append('/home/raoul/Desktop/j903/addons/api/python3') # change
path as appropriate
import numpy as np
from visidata import vd
jbase.init(False)
def j_mean(vals):
jbase.set('temp', np.array(vals))
e = jbase.do('var=:9')
r = jbase.get('var')
return e
vd.aggregator('j-mean', j_mean, 'get mean from J',type=float)
BaseSheet.addCommand('0', 'hello-world', 'status("Hello!")')
#------------------------------------------------------------------------
Following the same sequence as for 'avg', you can now type 'j-mean', which
triggers the issue.
For testing, if you press '0', 'Hello!' should appear on the status line.
Thanks to anyone who tries this!
Cheers,
Raoul
