xref Ack2 discussion under beyondgrep/ack2#517 and https://github.com/petdance/ack2/issues?q=is%3Aopen+label%3A--output
from ack3.
My additional desire is ability to create KWIC/KWOC index which would be much nicer with sprintf
in --output
.
(Yes, i'd need a post sort
but shell is good at piping to sort.)
for better KWIC/KWOC alignment
ack2 --output
can sorta do KWOC/KWIC with evil before/after vars
--output '$&^I$'"'"'^I|| $
' # KWOC
--output '$^I$&^I$'"'" # pseudo KWIC
but they’re nasty from Shell since must mix quote and dollar
and tabs don’t truly line up if width variation exceeds a tab width
need a sprintf with field-width for real thing …
(Our current ack2 --output
"evalmanages to not eval
'sprintf("%20s\t%20s\t%20s",$,$&,$'"'"')'
which is good for security but foils my KWIC/KWOC plans. Unless I use the eval evil i used to break eval previously.)
Related: should allow and recommend use English;
vars be used in --output
(is it already? No. In Ack2, $&
works but $MATCH
does not. Nor does ${^MATCH}
)
Related: need to have a variables available to the sprintf that are Filename and $. relative to filename.
