Visidata: [develop] concatenating selected source columns, from the Columns Sheet, does not work

[aborruso]

Small description

Hi opening the below CSV file, and then the Columns Sheet, if I select the two columns and then click on & I have an error.
I should have a column from concatenating selected source columns.

I'm using saul.pw/VisiData v2.-4dev

My input

a,b
hello,world
viva,las vegas

Actual result with screenshot

Steps to reproduce with sample data and a .vd

sheet   col row longname    input   keystrokes  comment
    SqliteSheet header  set-option  0       
    UsvSheet    delimiter   set-option  ␞       
    UsvSheet    row_delimiter   set-option  ␟       
            open-file   test.csv    o   
test            columns-sheet       C   open Columns Sheet: edit column properties for current sheet
test_columns        キa  select-row      s   select current row
test_columns        キb  select-row      s   select current row

Hey @aborruso!

Joins happen on the level of sheets, not columns, but I am curious about the thing you wanted to do!

Given this input

a,b
hello,world
viva,las vegas

What was your expected output?

[aborruso]

hey @anjakefala simply concatenate the two columns.

Joins happen on the level of sheets, not column

Are you sure?

Ah yeah, that's overloaded on the columns sheet. It's a bug, we can fix it. Though I'm not sure that it should stay bound to the & key. Do you use this feature often in 1.5.2, @aborruso ?

[aborruso]

To concatenate in vd way, fast and smart, it seems to me a great feature.

Thank you

[anjakefala]

Whoops @aborruso! Sorry for the confusion.

[anjakefala]

Thank you especially for making this bug report!

[anjakefala]

This should be fixed on develop now, @aborruso! =)

[aborruso]

It works, thank you!!

@anjakefala you took away my pleasure to close the issue :)

[aborruso]

@anjakefala is there a way to set in the options the column join separator ? If yes what's the name of the option?

Thank you

@aborruso it looks like it written only as space with the ch=' '

You would need another code change.

[aborruso]

@frosencrantz I'm not able to do it. I'm opening a feature request.

Thank you
