Three tarballs where a devShell was 5ce66d5 nandi yesterday1#!/usr/bin/env bash
2# The toolchain the web build needs, fetched by hand.
3#
Six verbs, and the last of the nix 2e24e64 nandi 16h ago4# Archives — Flutter (which carries Dart), a JDK, the Clojure CLI and Nim —
Three tarballs where a devShell was 5ce66d5 nandi yesterday5# pinned by version and by sha256, unpacked into `.toolchain/`, and put on a
6# PATH. That is the whole of it. No nix, no image, no devShell: a checkout
Six verbs, and the last of the nix 2e24e64 nandi 16h ago7# plus this script is a machine that can build any target here, and the same
8# script is what the Modal containers run.
9#
10# The Android SDK is the one thing not fetched by default, because only
11# `just build apk` wants it and it is large: `tools/toolchain.sh android`
12# fetches Google's command-line tools and lets sdkmanager finish the job.
Three tarballs where a devShell was 5ce66d5 nandi yesterday13#
14# Why not DotSlash, which the rest of the repo uses for its native libraries:
15# DotSlash hands out an *immutable* cached artifact, and Flutter is not one.
16# `flutter build web` downloads its engine artifacts into `bin/cache/` inside
17# its own SDK directory the first time it runs, so the SDK has to be writable
Six verbs, and the last of the nix 2e24e64 nandi 16h ago18# — which is the same reason the Android SDK below is fetched into a
19# directory of ours rather than used read-only from anywhere.
Three tarballs where a devShell was 5ce66d5 nandi yesterday20# A pinned URL and a checked hash give the reproducibility DotSlash is for;
21# the writability is what it cannot give.
22#
23# tools/toolchain.sh fetch whatever is missing
Six verbs, and the last of the nix 2e24e64 nandi 16h ago24# tools/toolchain.sh android ...and the Android SDK as well
Three tarballs where a devShell was 5ce66d5 nandi yesterday25# eval "$(tools/toolchain.sh env)" ...and put it on this shell's PATH
26# tools/toolchain.sh exec -- flutter --version
27#
28# `FRQ_TOOLCHAIN` says where it all lives; the default is `.toolchain/` at
29# the top of the checkout, and the container points it at a volume so the
30# fetch happens once across runs rather than once across containers.
