    Another nice project that I have used from time to time (and a very good source for insight) is the awk interpreter written in go https://github.com/benhoyt/goawk
  • Tool to interact with CSV

    No, I want exactly the opposite - it should be a , b,c as a single string field containing a literal comma, and c. For example, https://github.com/benhoyt/goawk has csv support. https://github.com/benhoyt/goawk/blob/master/docs/csv.md - more info.
  • Looking for programming languages created with Go

    There are quite a few re-implementations of scripting languages like Lua in Go. I've written an AWK interpreter in Go.

    github.com/benhoyt/goawk -> this library lets you embed an AWK runtime in your applications, very easy to use and useful for enabling some powerful scripting in things you build
  • Brian Kernighan adds Unicode support to Awk (May, 2022)
    13 projects | news.ycombinator.com | 20 Aug 2022
    This sounds reasonable. When the GoAWK creator tried to add Unicode support through UTF-8 he discovered that this had drastic performance implications (rendering some algorithms to be O(N^2) instead of O(N)), if done naive https://github.com/benhoyt/goawk/issues/35. Therefore the change was reverted till the more efficient implementation can be found.
    13 projects | news.ycombinator.com | 20 Aug 2022
    Yes, that's right. With my simplistic UTF-8-based implementation it turned length() -- for example -- from O(1) to O(N), turning O(N) algorithms which use length() into O(N^2). See this issue: https://github.com/benhoyt/goawk/issues/93

    Similar with substr() and other string functions, which when operating as bytes are O(1), but become O(N) when trying to count the number of codepoints as UTF-8.

    GNU Gawk has a fancier approach, which stores strings as UTF-8 as long as it can, but converts to UTF-32 if it needs to (eg: the string is non-ASCII and you call substr).

    It looks like Brian Kernighan's code has the same issue with length() and substr(). I'm going to try to email him about this, as I think it's kind of a performance blocker.

  • Ask HN: Is having a Personal blog/brand worth it for you?
    7 projects | news.ycombinator.com | 18 Jul 2022
    I'm not sure if it was via my personal website or just my GitHub profile, but I got my current job at Canonical due to the CTO there reaching out about my GoAWK project (https://github.com/benhoyt/goawk). I get regular recruitment emails because I have my CV/resume online: most of them are very low-effort, but 1 in 20 or something are interesting emails where the recruiter has actually looked at my website and will tailor it personally. I also just enjoy technical writing, and get joy out of sharing it on HN. So it's "worth it" for me.
