The name variable already includes highlighting in addition to the version info, so with the old code it would print the version info only if nameMatch is empty.

Fixes #2778.

I tested locally and confirmed that it still highlights the match in the name.

Anything holding this merge back? Just bumped into this issue too.

Me too! I think that merging this could avoid a lot of confusion for beginners.

I still want this. Didn’t realize there was a merge conflict though. I’ll have to look at that when I get a chance.

I'm not really sure what the state of nix search is on master right now. I especially don't know how to get it to reproduce the Nix 2.3 behavior of searching my channel (experimentally I can do something like nix search -f '<nixpkgs>' foo but this seems to just look up nixpkgs.foo instead of searching). Also, testing this right now, it's printing the version but not the name!

Looking at the code right now, it looks like the version info is indeed fixed, in that it now adds ($version) if the version is non-empty. But the code that's supposed to print the attribute is broken (at least, in the nix search -f '<nixpkgs>' foo invocation, probably because it's not actually searching but just looking up a specific attribute). And it's not printing the name (it calculates the name highlight and then throws it away).

nix/src/nix/search.cc

Lines 134 to 142 in 6678e98

auto name2 = hilite(name.name, nameMatch, "\e[0;2m");
if (results > 1) logger->cout("");
logger->cout(
"* %s%s",
wrap("\e[0;1m", hilite(attrPath2, attrPathMatch, "\e[0;1m")),
name.version != "" ? " (" + name.version + ")" : "");
if (description != "")
logger->cout(
" %s", hilite(description, descriptionMatch, ANSI_NORMAL));

It does appear that "don't omit version info" is indeed fixed in master (but not in 2.3-maintenance), but it's been traded for other breakage. Either way I'm going to close out this issue as the other breakage is orthogonal to the version.
