From 72d9dc02b2a6978ff0905843019bc563e4db8767 Mon Sep 17 00:00:00 2001 From: Eduardo Julian Date: Sun, 4 Oct 2015 19:59:22 -0400 Subject: - Removed the Lux source from the repo, as it now belongs to the lux/stdlib package. - Removed de Apacke Commons Compress library, as Lux libraries will now be packaged as .jar files instead of as .tar.gz files. - The compiler no longer packages libraries, as that task will now be left for the build system. --- project.clj | 3 +- source/lux.lux | 3303 --------------------------------------- source/lux/codata/function.lux | 27 - source/lux/codata/io.lux | 42 - source/lux/codata/lazy.lux | 56 - source/lux/codata/reader.lux | 30 - source/lux/codata/state.lux | 39 - source/lux/codata/stream.lux | 140 -- source/lux/control/bounded.lux | 14 - source/lux/control/comonad.lux | 52 - source/lux/control/enum.lux | 25 - source/lux/control/eq.lux | 11 - source/lux/control/fold.lux | 42 - source/lux/control/functor.lux | 12 - source/lux/control/hash.lux | 11 - source/lux/control/monad.lux | 107 -- source/lux/control/monoid.lux | 21 - source/lux/control/number.lux | 25 - source/lux/control/ord.lux | 41 - source/lux/control/show.lux | 11 - source/lux/data/bool.lux | 36 - source/lux/data/char.lux | 22 - source/lux/data/either.lux | 63 - source/lux/data/id.lux | 27 - source/lux/data/ident.lux | 33 - source/lux/data/list.lux | 344 ---- source/lux/data/maybe.lux | 46 - source/lux/data/number/int.lux | 93 -- source/lux/data/number/real.lux | 93 -- source/lux/data/text.lux | 195 --- source/lux/data/tuple.lux | 35 - source/lux/data/writer.lux | 31 - source/lux/host/io.lux | 60 - source/lux/host/jvm.lux | 377 ----- source/lux/math.lux | 80 - source/lux/meta/ast.lux | 113 -- source/lux/meta/lux.lux | 366 ----- source/lux/meta/syntax.lux | 306 ---- source/lux/meta/type.lux | 193 --- src/lux.clj | 5 - src/lux/lib/loader.clj | 24 +- src/lux/packager/lib.clj | 41 - src/lux/packager/program.clj | 42 +- 43 files changed, 38 insertions(+), 6599 deletions(-) delete mode 100644 source/lux.lux delete mode 100644 source/lux/codata/function.lux delete mode 100644 source/lux/codata/io.lux delete mode 100644 source/lux/codata/lazy.lux delete mode 100644 source/lux/codata/reader.lux delete mode 100644 source/lux/codata/state.lux delete mode 100644 source/lux/codata/stream.lux delete mode 100644 source/lux/control/bounded.lux delete mode 100644 source/lux/control/comonad.lux delete mode 100644 source/lux/control/enum.lux delete mode 100644 source/lux/control/eq.lux delete mode 100644 source/lux/control/fold.lux delete mode 100644 source/lux/control/functor.lux delete mode 100644 source/lux/control/hash.lux delete mode 100644 source/lux/control/monad.lux delete mode 100644 source/lux/control/monoid.lux delete mode 100644 source/lux/control/number.lux delete mode 100644 source/lux/control/ord.lux delete mode 100644 source/lux/control/show.lux delete mode 100644 source/lux/data/bool.lux delete mode 100644 source/lux/data/char.lux delete mode 100644 source/lux/data/either.lux delete mode 100644 source/lux/data/id.lux delete mode 100644 source/lux/data/ident.lux delete mode 100644 source/lux/data/list.lux delete mode 100644 source/lux/data/maybe.lux delete mode 100644 source/lux/data/number/int.lux delete mode 100644 source/lux/data/number/real.lux delete mode 100644 source/lux/data/text.lux delete mode 100644 source/lux/data/tuple.lux delete mode 100644 source/lux/data/writer.lux delete mode 100644 source/lux/host/io.lux delete mode 100644 source/lux/host/jvm.lux delete mode 100644 source/lux/math.lux delete mode 100644 source/lux/meta/ast.lux delete mode 100644 source/lux/meta/lux.lux delete mode 100644 source/lux/meta/syntax.lux delete mode 100644 source/lux/meta/type.lux delete mode 100644 src/lux/packager/lib.clj diff --git a/project.clj b/project.clj index 64b4141c2..7cc66da22 100644 --- a/project.clj +++ b/project.clj @@ -5,7 +5,6 @@ :url "https://www.mozilla.org/en-US/MPL/2.0/"} :dependencies [[org.clojure/clojure "1.6.0"] [org.clojure/core.match "0.2.1"] - [org.ow2.asm/asm-all "5.0.3"] - [org.apache.commons/commons-compress "1.10"]] + [org.ow2.asm/asm-all "5.0.3"]] :warn-on-reflection true :main lux) diff --git a/source/lux.lux b/source/lux.lux deleted file mode 100644 index 4d1c3fdef..000000000 --- a/source/lux.lux +++ /dev/null @@ -1,3303 +0,0 @@ -## Copyright (c) Eduardo Julian.
