How to align both header and data?

[agguser]

For example:

$ M() { echo "s,i,f\na,1,1.1\nbb,22,22.22" | mlr --c2p "$@"; }

$ M cat
s  i  f
a  1  1.1
bb 22 22.22

$ M format-values -i '%2lld' -f '%5.2lf'
s  i  f
a   1  1.10
bb 22 22.22

$ M put '$i=fmtnum($i,"%2lld"); $f=fmtnum($f,"%5.2lf")'
s  i  f
a   1  1.10
bb 22 22.22

But what I want is that both header and data has same alignment:

s   i     f
a   1  1.10
bb 22 22.22

It would be great if there is ralign verb to right-align specific fields, e.g. mlr --c2p ralign -f i,f.

looking ...

I think you just want mlr --opprint --right ... ?

$ mlr --c2p cat sif.csv
s  i  f
a  1  1.1
bb 22 22.22

$ mlr --c2p --right cat sif.csv
 s  i     f
 a  1   1.1
bb 22 22.22

I want to right-align only "number" columns (i, f), not "text" columns (s).

D'oh.

Yes I had imagined this some while back but wasn't sure if there were sufficient demand. Now that there are two of us who have thought of this ... probably rises to the level of being worth coding up. ;)

Thanks. By the way, on second thought, instead of ralign verb, it should be --ralign {a,b,c} option for pprint.

Workaround:

$ echo "s,i,f\na,1,1.1\nbb,22,22.22" | mlr --c2t format-values -f '%.2lf' | column -t -s $'\t' -R 3
s   i       f
a   1    1.10
bb  22  22.22

One more interested!

I got here also looking on how to right-align only some of the columns in a pprint output. I'm generating a small report tool that will list a set of data consisting on text, numbers (integers and floats) and times (in the format [[dd-]hh:]mm:ss). Humans need numbers to be right aligned to be easy to skim over them (comma aligned, to be more precise, which is equivalent to right aligned in case of integers and floats formatted with a fixed number of decimals). On the other hand, text needs to be left aligned for human comfort. In the middle is the time data: it is handled as a string, but it should be right aligned as well so the hours, minutes and seconds are always aligned.

Some kind of "alignment specification" would be good. The "ralign" proposal seems good, but I want to add something:

• Given that left alignment is the default, per column right alignment is missing... and it would be good to have "center" ability in the same go. In fact, I would go for a parameter to specify default alignment (left, right, center) and a verb to specify column alignments.
• Giving the columns as an option to pprint instead of a verb could make it difficult to apply this option to newly created fields on the fly through a put command.

+1 that --ralign {a,b,c} option would be great or some kind of alignment "spec"
