From 9b334397f55b70689ff1d8f7d6767a34834e85b6 Mon Sep 17 00:00:00 2001 From: Sebastian Holtermann Date: Thu, 22 Aug 2019 16:34:40 +0200 Subject: Source sweep: Use cmStrCat for string concatenation This patch is generated by a python script that uses regular expressions to search for string concatenation patterns of the kind ``` std::string str = ; str += ; str += ; ... ``` and replaces them with a single `cmStrCat` call ``` std::string str = cmStrCat(, , , ...); ``` If any `` is itself a concatenated string of the kind ``` a + b + c + ...; ``` then `` is split into multiple arguments for the `cmStrCat` call. If there's a sequence of literals in the ``, then all literals in the sequence are concatenated and merged into a single literal argument for the `cmStrCat` call. Single character strings are converted to single char arguments for the `cmStrCat` call. `std::to_string(...)` wrappings are removed from `cmStrCat` arguments, because it supports numeric types as well as string types. `arg.substr(x)` arguments to `cmStrCat` are replaced with `cm::string_view(arg).substr(x)` --- Source/cmGlobalGenerator.cxx | 163 ++++++++++++++++--------------------------- 1 file changed, 62 insertions(+), 101 deletions(-) (limited to 'Source/cmGlobalGenerator.cxx') diff --git a/Source/cmGlobalGenerator.cxx b/Source/cmGlobalGenerator.cxx index c815fdbdc3..e145ad4647 100644 --- a/Source/cmGlobalGenerator.cxx +++ b/Source/cmGlobalGenerator.cxx @@ -205,9 +205,7 @@ void cmGlobalGenerator::ResolveLanguageCompiler(const std::string& lang, cmMakefile* mf, bool optional) const { - std::string langComp = "CMAKE_";
