When you've reached the last +paragraph of the section, I fall over, the boxes land on top of me and all over the floor, I'm +covered in spaghetti, and in an exasperated voice I shout \"There's gotta be a better way!\" + +When setting up a new computer for software development, I want to go from `git clone` to `make` in +as little time as possible (adjust that for your VCS and build system of choice.) In the old days, +this meant manually installing the dependencies through the distro package manager. If things are +organized, the project README will have a list of what is needed and it's not so bad. If things are +less organized, it's a cycle of installing packages and running `./configure` or whatever until it +succeeds. Hopefully none of the dependencies are too new to be found in the distro. And when +working on multiple projects, hopefully there's no conflicts between the dependencies required for +each of them, because your development environment is the entire system and there's no way to +isolate different projects from each other. + +Of course, different programming languages provide their own sets of tools for managing multiple +projects. Python has virtualenv, Ruby has rvm and bundler, Node has nvm and npm, etc. But their +domain is restricted to only the dependencies for that language and their runtimes. A system +package manager is needed to bootstrap their use. + +Nowadays it's \"just use Docker.\" Docker's take is that all this package management stuff is just +too complicated. Instead, just create a disk image per project that encapsulates this hodgepodge of +package managers and bespoke, artisinal, small-batch builds that gets run in isolation via Linux +namespace magic. It works, of course, but I think Dockerfiles are clunky and the rather extreme +level of isolation is usually unnecessary and makes things overly complicated for projects that need +to interact with, say, the windowing system of the host computer. A lot of people are happy with +Docker, though. Maybe you are, too. That's fine! + +What I really want to say is \"Computer, provision a development environment containing Guile 3, +SDL2, make, and texinfo!\" and have Majel Barrett-Roddenberry tell me that all of those things have +been made available to me on my host system. No container, no virtual machine. It shouldn't matter +if I have Guile 2 installed system-wide, Guile 3 should still be what's used in the context of the +project. This is how Guix works and it's very good and cool and I'm going to tell you all about how +I use it." + ;; "The quick brown fox jumps over the lazy dog.\nFive hexing wizard bots jump quickly." + ) + +(define (stats-message) + (format #f "fps: ~1,2f" + (/ 1.0 avg-frame-time))) + +(define (load) + (script + (forever + (sleep 60) + (set! stats-text (stats-message))))) (define (draw alpha) - (draw-text "The quick brown fox jumps over the lazy dog.\nFive hexing wizard bots jump quickly." - (vec2 140.0 240.0))) + (draw-text text position) + (draw-text stats-text stats-position) + (let ((current-time (elapsed-time))) + (set! avg-frame-time + (+ (* (- current-time start-time) 0.1) + (* avg-frame-time 0.9))) + (set! start-time current-time))) + +(define (update dt) + (update-agenda 1)) + +(define (key-press key modifiers repeat?) + (when (eq? key 'q) + (abort-game))) -(run-game #:draw draw) +(run-game #:draw draw + #:key-press key-press + #:load load + #:update update + #:window-title "text rendering" + #:window-width 1280 + #:window-height 720) -- cgit v1.2.3
