bench_intro(3tcl)

💖 bench_intro — bench introduction 💖

okay bestie, welcome to bench_intro from the 3tcl manual, filed under Benchmarking/Performance tools. this is literally your lil orientation tour before you go feral writing performance tests. let's get into it 🦋

✨ NAME ✨

bench_intro — bench introduction. that's it, that's the whole name section, she's lowkey iconic for saying so little 💅

---

🌸 DESCRIPTION 🌸

so bench (short for benchmark tools, iykyk) is not one single thing — it's a whole friend group of related but different entities that work together so you can create and execute performance test suites (aka benchmarks) without losing your mind. and the members of the group are:

1. A tcl based language for declaring test cases. a test case is represented by a tcl command that declares all the various parts you need to actually execute it — think setup, cleanup, the commands to test, etc. very structured, very demure.
2. A package that gives you the ability to execute test cases written in that language. she runs the vibes.

which of the more detailed documents actually matters to you depends entirely on your role in the benchmarking process, bestie:

1. A writer of benchmarks needs to understand the bench language itself, no shortcuts. if you're a beginner to bench, read the more informally written bench language introduction first. once you've digested that, the formal bench language specification should actually become understandable (slay). if you're already experienced with bench, you might only need that last document from time to time to refresh your memory. periodt.
2. A user of benchmark suites written in the bench language needs to know which tools are available for use. at the bottom level sits the package bench, providing the basic facilities to read and execute files containing benchmarks written in the bench language, and to manipulate benchmark results. she's the foundation, she's the main character 🫶

🎀 HISTORICAL NOTES 🎀

lore drop 🕰️ — this module and package have been derived from Jeff Hobbs' tclbench application for the benchmarking of the Tcl core, and its ancestor "runbench.tcl". so yeah, we're standing on the shoulders of some very real ones 💜

💀 BUGS, IDEAS, FEEDBACK 💀

not to be dramatic but this document, and the package it describes, will undoubtedly contain bugs and other problems. like, that's just the deal. please report such in the category bench of the Tcllib Trackers at [http://core.tcl.tk/tcllib/reportlist]. and please also report any ideas for enhancements you may have for either the package and/or the documentation — we want the glow-up ideas too ✨

when proposing code changes, please provide unified diffs, i.e. the output of diff -u. no cap, this is the way.

note further that attachments are strongly preferred over inlined patches. attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar. yes, that exact button. the left-most one. go get it 💅
