Resholve Alternatives

resholve reviews and mentions

• What is the Flakes version of "reproducible interpreted scripts"?
  6 projects | /r/NixOS | 26 Apr 2023

  I'm also not 100% on whether it answers the question, but I imagine you're thinking of https://github.com/abathur/resholve (doc in nixpkgs: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/misc/resholve/README.md)

• modular bash profile scripting with shellswain
  2 projects | /r/programming | 24 Jan 2023

  I intend to eventually find some time to figure out how feasible it would be to use https://github.com/abathur/resholve or wrapper techniques to bolt basalt (and perhaps other bash PMs) on to the nix ecosystem and nix-package some of your libraries.

• Is there a good way to programmatically determine how many inputs some function can support?
  3 projects | /r/bash | 16 Jan 2023

  (I'd love to have this ability for https://github.com/abathur/resholve to reliably identify arguments to one command that are also external commands/programs that it will in turn exec. I can't imagine trying to start it until/unless I have any bright ideas about how that executable spec and a parser for it would work.)

• Could someone give me an example how I would have multiple "commands" in default.nix?
  2 projects | /r/NixOS | 13 Oct 2022

  In https://github.com/abathur/resholve/blob/master/default.nix and https://github.com/abathur/resholve/blob/master/shell.nix you can see one approach to extending that line of thought to the default.nix itself.

• Building the Future of the Command Line

  Completions have in general been of interest, though the shell-specific completions I've looked at so far were all too dynamic.

  I'd forgotten all about Fig since I saw your launch post here last year, so thanks for reminder. (I don't think I had quite started to work on parsing specific external commands, yet. Was still focused on just identifying the likely presence of exec in the executables.)

  Are you familiar with the parse code? Are you handling painful stuff like combined short flags with a trailing option? (If I ferreted out some of the more painful cases I've had to wrangle, I am curious if you'd have a gut sense of whether your approach handles it. Would you mind if I reach out? I am working on this for https://github.com/abathur/resholve)

• Devbox: Instant, easy, and predictable shells and containers
  16 projects | news.ycombinator.com | 25 Aug 2022

  @dloreto @robrich A little aside from the announcement, but since it seems like you both work on this I wanted to surface something that came up down in a subthread:

  I'm curious if you attempted to support macOS by doing this with Nix's dockerTools and cross-compiling (there may be better sources, but it's at least hinted at in https://nix.dev/tutorials/building-and-running-docker-images...)? If so, I'm wondering where that failed or bogged down?

  ---

  Background: I build a tool (https://github.com/abathur/resholve) for ~packaging Bash/Shell (i.e., for demanding all dependencies be present). The tool's technically agnostic, but I built it specifically to fix Shell packaging in Nix.

  I think it could benefit a lot of other Shell projects, since one of Shell's big tribulations is dealing with heterogenous environments, but most Shell projects wouldn't see much reason to endure the pain of adopting Nix if they still had to support the heterogenous environments.

  Much like you're doing here, I've entertained figuring out how to build a Nix-based packaging flow that can generate deployable standalone bundles or containers. It'd be a heavy way to bundle Shell, but I imagine some projects would take the tradeoff for predictability and reduced support load. But since it would need to take place within a Nix build, I'd need to cross-compile for it to work on macOS. Hoping you know if it's a dead-end or not :)

• Ask HN: Why aren't code diagram generating tools more common?
  6 projects | news.ycombinator.com | 4 Jun 2022

  For a concrete example, I've been developing a tool (https://github.com/abathur/resholve) that can ~build/link Bash/Shell scripts--i.e., rewrite them with external executables converted to absolute paths. (This helps ensure dependencies are known, declared, present, and don't have to be on the global PATH for the script to execute cleanly.)

  There's a devilish sub-problem, which is that any given executable can potentially exec arbitrary arguments. For now I handle this with a very crude automated binary/executable analysis that needs to be augmented by human source analysis. Deep multi-language source analysis wouldn't be very scalable, but I suspect fairly-standardized structural annotations could improve the results in a scalable way.

  I have to imagine there are other applications of the same information.

• I wrote an article about creating unit-tests and mocks for POSIX shells

  I'm not 100% sure if you see the minimal PATH dependencies as a problem or not--so this may or may not help--but I develop https://github.com/abathur/resholve to make it easier to package Shell in Nix/nixpkgs by rewriting invocations of external dependencies in Shell scripts to absolute paths--and shunit2 is one of the Nix packages that I've updated to use resholve.

• On Env Shebangs

  I came here to say this, too :)

  But, of course, it still isn't a silver bullet...

  1. You still have to have a sane PATH. A fair amount of the Nix install-related issues that get opened are PATH problems, and you can also run into problems with PATH in cron/launchd.

  2. You still have to know what the script depends on. This can get tricky beyond small scripts you wrote yourself. (I write a tool for ~linking/resolving external dependencies in Shell scripts, https://github.com/abathur/resholve. As I've been working on converting some of nixpkgs' existing Shell packages to use it, I almost always find dependencies the initial packager missed.)
