From 6f6a181aacdd8f963c05862b01e92ade2ae803bc Mon Sep 17 00:00:00 2001 From: Yuka Takahashi Date: Wed, 26 Jul 2017 13:36:58 +0000 Subject: [PATCH] [Bash-autocompletion] Show HelpText with possible flags Summary: `clang --autocomplete=-std` will show ``` -std: Language standard to compile for -std= Language standard to compile for -stdlib= C++ standard library to use ``` after this change. However, showing HelpText with completion in bash seems super tricky, so this feature will be used in other shells (fish, zsh...).
