piping through csvlens and echoing a column from the selected row on exit

[cabrrtt]

Loving csvlens @YS-L. Like @elferherrera suggested, I'm finding this an perfect partner to nushell to browse through csv such as:

ps | to csv | csvlens

What I would love to be able to do is to pipe on from csvlens, meaning that csvlens can take a switch to echo a named column from the selected row on exit. Kind of like a columnar fzf

[YS-L]

Interesting! Haven't thought of piping on from csvlens. Do you mean echoing the value of a particular cell in the table?

[cabrrtt]

Yes, just that. To illustrate, instead of this using fzf:

ps | to csv | fzf | split row ',' | get 0 | kill $in

You might do

ps | to csv | csvlens --echo-column pid | kill $in

[cabrrtt]

Or perhaps that would more logically be --echo-cell

[YS-L]

I like the option --echo-column. Just added that in the main branch.

[cabrrtt]

Just built and tested. This works great @YS-L. Thanks!

[miketheman]

Thanks for this feature! Would you consider an adaptation to allow piping through, so that there's no interactive session, rather emits to stdout immediately?

[elferherrera]

It would be nice if this selection can be done inside csvlens. That one can select a column or a cell and then return the values as a comma separated string

[YS-L]

@miketheman Could you show an example usage without interactivity? csvlens is intended for interactive usage, so I suspect there might be better tools for that purpose.

[miketheman]

@YS-L my example was largely intended for a packaging/testing purpose and automated testing that the compiled binary functions correctly without a human confirmation 😁

@elferherrera Yes, that makes a lot of sense. Supporting column and cell selection is one of the improvements that I plan to implement.
