Conversation
Topfew is a dependency-free Golang command-line utility. The command is "tf".
If you entered
tf -f 7
that would do the equivalent of
awk '{print $7}' | sort | uniq -c | sort -nr | head
i.e., find and print out the ten most common values of field number 7
in records read from stdin. It has lots of options to select fields.
It is significantly faster than the shell pipeline above and, in the
case where it's applied to a named file as opposed to stdin, much much
faster because it divides the file into segments and process them
in multiple threads.
The github repo is https://github.com/timbray/topfew
It has decent README.md and CONTRIBUTING.md files and
I'm working on an INSTALLING.md which, if this is accepted, would
include "brew install topfew".
Its development is rather fully described in a series of blog posts,

The problem was that the build step was failing, it didn't like *std_go_args(out: bin/"tf"). Having fixed that, I discovered that pipe_output("#{bin}/tf -f 2", "foo bar") also doesn't work, while my original formulation, assert_match "1 bar", shell_output("echo 'foo bar' | #{bin}/tf -f 2") does work. Are we perhaps using a different version of brew?

I might think the binary might need a better name than tf, as tf is popular alias to terraform. |

Pardon the sloppy follow-up commit messages. I'm happy to let brew's CI go ahead and auto-squash, I haven't done a rebase/squash in like a year and would be happy to avoid re-learning that stuff. |
Hmm, maybe? Terraform is about to become known as OpenTofu… Maybe "tfw". Maybe produce two binaries, "topfew" and "tf"? I don't have strong opinions on this. |
yeah, tf could be used for both (it would mostly ease the |

if you look at coreutils for gnu drop-in replacements, we did the rename as well, so is true for jruby stuff, I dont think it is that beneficial to introduce the conflicts. In other words, you probably should consider to do the tap host. |

Thanks for the input. Unfortunately I'm a newbie here and I'm not sure I understand.
For coreutils, I guess you mean as described in https://apple.stackexchange.com/questions/69223/how-to-replace-mac-os-x-utilities-with-gnu-core-utilities? In this case you put a "g" prefix but also allow people to use unprefixed form by changing PATH. So you are suggesting that the "topfew" form would be linked but "tf" would still be available via changing PATH? (Sorry if this is a dumb question.) I don't understand the jruby comment, I have used "brew install jruby" in the past. I have never seen jruby referred to as anything but jruby.
Um, what does "do the tap host" mean? I'm new to Brew. I would like to say that I'm serious about the status of Terraform, see OpenTofu Announces Fork of Terraform - Terraform is no longer open-source! And it's owned by IBM. I wonder if it's necessary for Brew to make life easier for users of non-OSS IBM product. |

Thank @SMillerDev for the sign-off. Is there anything I need to do now to move this along in the Brew context? |
