我通常在我的项目中有一项政策,即永远不要在文本文件中创建超过80行长度的行,因此可以在各种编辑器中轻松编辑它们(您知道这很重要)。但是,有了CMake,我遇到了一个问题,我不知道如何将一个简单的字符串拆分为多行,以避免出现一条大行。考虑以下基本代码:
I usually have a policy in my project, to never create lines in text files that exceed a line length of 80, so they are easily editable in all kinds of editors (you know the deal). But with CMake I get the problem that I do not know how to split a simple string into multiple lines to avoid one huge line. Consider this basic code:
set(MYPROJ_VERSION_MAJOR "1") set(MYPROJ_VERSION_MINOR "0") set(MYPROJ_VERSION_PATCH "0") set(MYPROJ_VERSION_EXTRA "rc1") set(MYPROJ_VERSION "${VERSION_MAJOR}.${VERSION_MINOR}.${VERSION_PATCH}-${VERSION_EXTRA}")它已经超过了80行限制。那么,如何在CMake中将一行分成多行而不引起冗长(多个 list(APPEND ...)等)?
It already exeeds the 80 line limit. So how do I break a line in CMake into multiple lines without getting to verbose (multiple list(APPEND ...) or the like)?
推荐答案CMake 3.0及更高版本的更新:
行继续是 \ 可能。参见 cmake-3.0-doc
message("\ This is the first line of a quoted argument. \ In fact it is the only line but since it is long \ the source code uses line continuation.\ ")CMake版本的可用性:
Debian Wheezy(2013):2.8.9 Debian Wheezy-backports:2.8.11 Debian Jessy(2015):3.0.2 Ubuntu 14.04(LTS):2.8.12 Ubuntu 15.04: 3.0.2 Mac OSX:cmake-3可通过自制软件, Macports 和查找 Windows:cmake-3可通过巧克力
