From 0f67be5258e25d8cf68b2a50535e82dd0c757206 Mon Sep 17 00:00:00 2001 From: Ignacio Burgueño Date: Tue, 14 Apr 2015 02:15:31 -0300 Subject: Adds --only-deps flag to the 'build' command. As discussed in #287, adds a new flag (--only-deps) to the 'build' command, so only the dependencies of a rock are installed, and not the rock itself. --- src/luarocks/build.lua | 33 +++++++++++++++++++++++---------- src/luarocks/util.lua | 1 + 2 files changed, 24 insertions(+), 10 deletions(-) (limited to 'src') diff --git a/src/luarocks/build.lua b/src/luarocks/build.lua index 96191b11..70a53e14 100644 --- a/src/luarocks/build.lua +++ b/src/luarocks/build.lua @@ -37,6 +37,8 @@ or the name of a rock to be fetched from a repository. rockspec.
