Ensure all functional scripts are (a) executable (b) have shebang This is good for shebang, and also good for future build system simplifications 2024-05-28 16:43:04 +00:00			`#!/usr/bin/env bash`

Add a mechanism for derivation attributes to reference the derivation's outputs For example, you can now say: configureFlags = "--prefix=${placeholder "out"} --includedir=${placeholder "dev"}"; The strings returned by the ‘placeholder’ builtin are replaced at build time by the actual store paths corresponding to the specified outputs. Previously, you had to work around the inability to self-reference by doing stuff like: preConfigure = '' configureFlags+=" --prefix $out --includedir=$dev" ''; or rely on ad-hoc variable interpolation semantics in Autoconf or Make (e.g. --prefix=\$(out)), which doesn't always work. 2016-08-17 13:12:54 +00:00			`source common.sh`
