c++11 - 最终并覆盖 Geany 中的 C+11 说明符着色

Question

我使用 Geany 1.22 进行开发，但在 C++11 关键字的着色方面遇到了问题。

这是我的 .cpp 配置文件:filetypes.cpp

comment_close=
# this is an alternative way, so multiline comments are used
#comment_open=/*
#comment_close=*/

# set to false if a comment character/string should start at column 0 of a line, true uses any
# indentation of the line, e.g. setting to true causes the following on pressing CTRL+d

# This setting works only for single line comments
comment_use_indent=true

context_action_cmd=

[build_settings]
# %f will be replaced by the complete filename
# %e will be replaced by the filename without extension
# (use only one of it at one time)
compiler=g++ -Wall -c "%f"
linker=g++ -Wall -o "%e" "%f"
run_cmd="./%e"

如果我写:

class MyClass
{
};

定义一个新类，然后将 MyClass 的颜色设置为 globalclass 的颜色(这是与 type 关联的颜色)

但是当我用 C++11 编写时:

class MyClass final
{
};

然后 final(而不是 MyClass)设置为 globalclass 的颜色。如果我将 final 添加到主要关键字列表中，那么它会设置为 word 的颜色，这很好，但是 MyClass 仍然不是解释为 globalclass。

如何解决这个问题？

Answer 1

问题似乎是在 C++11 中，final 和 override(我怀疑你在那里会遇到同样的问题)实际上并不是关键字。它们是只有在特定上下文中才具有特殊含义的标识符。这意味着您实际上不能随时“只是”为这些标识符赋予颜色，您需要了解它们的上下文。

幸运的是，Geany 1.23 已经为您完成了对 C++11 的支持。不幸的是，Geany 1.23 也不是 100% 正确。也就是说，如果编写 int final = 123; 那么 final 将被着色为关键字(而它实际上不是关键字)。所以他们实际做的是:他们将 final 添加为主要关键字，这并不完全正确，但它有点管用。

所以我的建议是要么从 this link 下载最新版本的 Geany，要么尝试以下配置文件:(来自 Geany 1.23)

但是，我有点怀疑如果不更新到下一个版本的 Geany，上面的方法是否会起作用，因为你说仅仅添加“final”作为主要关键字对你不起作用。

另一方面，如果您仍想手动执行此操作，请查看 the manual on lexer properties。

希望对您有所帮助。
