[9fans] Acme: how to search only in selection

[dexen deVries]

Hi list,


how do I perform right-click search only in highlighted range?


Use case: while editing C-like code (PHP), I highlight whole function by
clicking on opening brace and would like to search only the selection for all
occurrences of some symbol stored in window's tag. Preferably with wrap-around
after reaching end of the selection :D

I don't know a direct way and am afraid there is no one immediately
ready to use.
Once the text is selected, however, you may fairly easily copy it to a
new window, and then rightclicking should work, even with a
wrap-around...

Otherwise, using '>g pattern' will make a list, in the Error window,
of lines where the pattern is, so then you can go through it.

This sounds like a good feature to add though. Might hack on this tonight.

The real question is how to handle the next selection; tracking two
dots seems wrong.

i believe Ruda's solution comes very close: pipe selected range to separate
window (+Error, if you must) and then operate on it. However, it is not good
enough: line numbers do not match original file.

Is there a way to recover range of dot from script ran from Acme window? I
couldn't find; expected the `acme/$winid/addr' file to contain char ranges of
dot after `echo addr=dot | 9p write acme/$winid/ctl', but the
`acme/$winid/addr' stays `0 0'. Using plan9port here.

If there was a way to get $firstLine, $lastLine or $firstChar, $lastChar, it'd
be easy enough to filter lines with sed or awk for match of both RegEx and line
number or char range. Or to re-number lines as output by grep.

1972 - Dennis Ritchie invents a powerful gun that shoots both forward and
backward simultaneously. Not satisfied with the number of deaths and permanent
maimings from that invention he invents C and Unix.

i think it crosses some line to imply that dennis intended folks
physical harm, even if the whole thing is absurd.

for me, almost everything goes in comedy. if anything, more regretable is lack
of attribution to ken et al.
