Yep, you're right, thanks for the clarification. I was simplifying (never a good idea for a highly technical audience :-) because most people haven't heard of threaded code but have heard of bytecode. My Third compiler used direct

My dad, who was a minister by day and Forth hacker by night, got me into programming when I was a teenager, and Forth and x86 assembly were my first languages. I wrote a small self-hosting Forth compiler for 8086 DOS ( https://git

While I love the tech behind this (as well as the good article and fun demo video), I'm very skeptical that this will be a good approach for most web apps. I hope it doesn't turn into Python programmers suddenly pulling in 7MB of

I think your pushback is good - I didn't think the explanation about multiple cores made sense either. The Go runtime doesn't magically spread things across cores. However, I don't think your sarcasm helps the conversation.

Berry's response to that (and similar) letters is quite sharp, but fair, I thought: > I am also surprised by the meanness with which two of these writers refer to my wife. In order to imply that I am a tyrant, they suggest by both d

Compatibility: so it can run all the existing AWK scripts without modification, and people can refer to existing AWK documentation when writing scripts, and they'll just work under GoAWK. For a 45-year old language, it's actually

A beautiful, big full moon was visible over Christchurch, New Zealand tonight, and I was just talking about this with the kids. It fascinates me that scientists have sent us up to the moon, but can't figure out exactly why it appears b

Odd, I find the standard library very full-fledged and useful, including the strings package. I've almost never needed to reverse a string, except in interviews. :-) The stdlib has a full (and good) HTTP server with HTTP/2 and TLS

My thoughts on his points, from someone who really likes Go and has used it heavily on small and large projects (1M LoC): 1. Probably a matter of taste, but I love this feature, just because of the lack of noisy public/private keywords

I highly recommend you learn the basics of AWK, which is a little language that lets you match on and run commands on every line of input (so AWK "scripts" are usually one-liners). The very basics can be learn in 5-10 minutes, t

You're not wrong, I should have just said .gz (though that really wasn't my point :-).

Definitely agree. I really like that ripgrep is fast, but I mainly use it for its better UX for what I do every day: search code. If ripgrep wasn't any faster than grep, but was still recursive by default and ignored .gitignore et al,

Just my two cents as someone who isn't associated with Sourcegraph: I also thought this comment was overly snarky and not exactly true. Their main product is a really good code search/navigation tool, and even Code Insights is har

This is definitely true, and I wouldn't fault anyone for using Ruby or Python to write the initial version of their startup. However, there's a difference between initial productivity and ongoing productivity (maintenance). Static

Yeah, this seemed fishy to me too (I made a similar comment here: https://www.reddit.com/r/golang/comments/uo5mix/comment/i8dn... ). It seems the mattn/cgo version is doing a constant amount of

I've now updated the benchmarks to avoid huge.csv: the write benchmarks now write a big 1GB, 20-column CSV and the read benchmarks use that same CSV: https://github.com/benhoyt/goawk/commit/07eb4505a7f64c

I'm not considering adding general structured formats like XML or JSON, as they don't fit AWK's "fields and records" model or its simplistic data structure (the associative array) very well. However, I have consider

Ah, true -- that would be a good comparison to do, or section to add the the docs (csv.md in the repo). I'll add it to my to-do list!

Yep, this works fine (in GoAWK, gawk, and mawk, though not in original awk): $ cat t.usv && echo id␟name␟age␞1␟Bob "Billy" Smith␟42␞2␟Jane Brown␟37 $ goawk -F␟ -vRS=␞ -vOFS=, '{ print $1, $2, $3 }' t.us

Thanks. I haven't tried this, but it should actually work already in standard AWK input mode with FS and RS set to those Unicode separators. I'll test it tomorrow when back at my laptop.
