From fafbf4a1bf635d5eea049cf561fbf8aa293c8e2b Mon Sep 17 00:00:00 2001 From: Daniel Mueller Date: Sat, 11 Apr 2020 13:23:52 -0700 Subject: Merge remaining bits of args.rs into main.rs This change removes the args module by moving all remaining functionality in it into main.rs. The result is arguably a nice consolidation of all context related definitions in a single module. --- src/arg_util.rs | 2 +- src/args.rs | 99 ------------------------------------------------ src/commands.rs | 112 +++++++++++++++++++++++-------------------------------- src/main.rs | 85 ++++++++++++++++++++++++++++++++++++++++- src/pinentry.rs | 6 +-- src/tests/mod.rs | 2 +- 6 files changed, 134 insertions(+), 172 deletions(-) delete mode 100644 src/args.rs diff --git a/src/arg_util.rs b/src/arg_util.rs index c16c326..439a594 100644 --- a/src/arg_util.rs +++ b/src/arg_util.rs @@ -46,7 +46,7 @@ macro_rules!
