Products that do what Jeval allows to run Java scripts as ordinary executable files does

With new version of jeval we added support for shebag (#!) directive which is available in Unix-like operating systems. It allows to run scripts written in Java without calling jeval. Instead of: jeval script.java You can run it directly as ordinary executable file: ./script.java For that to work you need to put following line as a first line of script.java: #!/usr/bin/env jeval And make file executable: chmod u+x script.java https://github.com/lambdaprime/jeval

   Jless, a command-line JSON viewer▲344

   Hey, Hacker News! Today I'm proud to release jless, a command-line JSON viewer. jless provides a JSON viewing experience similar to what you see in a browser's network tab in the developer console, but from the comfort of your terminal, with a whole suite of vim-inspired key bindings to easily manipulate your view of the data and full-text regex search. I'm sure many of you have some piped together some combination of cat, jq and less before; hopefully jless can replace that usage (hence the name). It supports newline delimited JSON too, so it can handle any output from jq. I built jless to…

   Eno – A lightning fast, user-friendly YAML/TOML alternative▲102

   eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone! Last but…

    I wrote a Bash library▲10

    Shelon: https://github.com/housni/sheldon It's not a framework, it's a library. It attempts to mimic function names in Python. Most functions work in Bash 4.3+ but there are those that work on older versions. The 'help' target in Makefile is on crack! Check the issues in that repo for upcoming features. Useful for DevOps Engineers or anyone who has to write Bash scripts.

    Inspired by Simon Willison's blog post that was catalyzed by this HN post: https://news.ycombinator.com/item?id=34598024 wasm_exec is a Wasm-powered, sandboxed implementation of exec() for safely running dynamic Python code There are number of use-cases emerging that require arbitrary code execution, often code that is generated by LLMs (Large Language Models) like ChatGPT. This can enable some really cool functionality - like generative BI or website generation - but also introduce a massive security flaw if implemented via eval() or exec(). This is because arbitrary code can…

    Automation the KISS way. No YAML involved▲5

    Hello HN, I like Ansible as a tool for automation to perform tasks on multiple remote hosts. But like many of you, I'm sick of the custom YAML DSL that many of this kind of tools provide. How many times have we said "just give me a true scripting language!" ? That's why I started this project `tricorder` (as in Star Trek's tricorder, a simple device to do pretty much anything required by the plot). For now, it's only a tool to execute a command on multiple hosts (like ansible, but without the YAML) and returning the outputs as JSON so you can query it with other tools like `jq` in your bash…
