From 47a6bb2d5ba9c8488ef1588c99fbebd8d9417374 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 12 Nov 2019 06:56:31 -0500 Subject: externals: Update httplib Since the introduction of this library, numerous improvements have been made. Notably, many of the warnings we would get by simply including the library header have now been fixed. This makes it much easier to make conversion warning an error. --- externals/httplib/httplib.h | 4703 ++++++++++++++++++++++++++++--------------- 1 file changed, 3038 insertions(+), 1665 deletions(-) (limited to 'externals') diff --git a/externals/httplib/httplib.h b/externals/httplib/httplib.h index dd9afe693..fa2edcc94 100644 --- a/externals/httplib/httplib.h +++ b/externals/httplib/httplib.h @@ -1,357 +1,768 @@ // // httplib.h // -// Copyright (c) 2017 Yuji Hirose.
