Qt Creator 项目构建变量从何而来? [英] Where Qt Creator project build variables come from?

问题描述

On Qt Creator Tools>Options>Build &运行>Default Build Properties 默认构建目录具有根据变量定义的值

On Qt Creator Tools>Options>Build & Run>Default Build Properties the Default build directory has the value defined in terms of variables

../%{JS: Util.asciify("_build-%{CurrentProject:Name}-%{CurrentKit:FileSystemName}-%{CurrentBuild:Name}")}

导致类似

_build-Project1-Desktop_Qt_5_15_2_MSVC2019_64bit-Debug

1. 这些变量(CurrentProject:Name、CurrentKit:FileSystemName 和 CurrentBuild:Name)从何而来?

1. From where those variables (CurrentProject:Name, CurrentKit:FileSystemName and CurrentBuild:Name) come from?

我想生成一些不同的(更短的)，也许像

I would like to generate something different (shorter), perhaps like

_x86-debug 或 _x86d 或 _x64-debug 或 _x64d

我应该寻找哪些变量?

推荐答案

如果您单击重置"按钮附近和插入变量"工具提示上方的 A->B 按钮，您将看到一个列表Qt Creator 中可用的全局变量

If you click on the A->B button near the Reset button and above the tooltip that says "Insert Variable", you'll see a list of the global variables available in Qt Creator

这是同一个列表，但更容易阅读:https://www.programmersought.com/article/73762199051/

This is the same list, but easier to read: https://www.programmersought.com/article/73762199051/

这是内部变量的官方文档:https://doc.qt.io/qtcreator/creator-project-settings-environment.html#using-qt-creator-variables

And this is the official docs for internal variables: https://doc.qt.io/qtcreator/creator-project-settings-environment.html#using-qt-creator-variables

你可以这样做:
../%{JS: Util.asciify("_x64-%{ActiveProjectBuildConfig:Type}")}

或者您可以为您的架构设置一个环境变量，无论是 x86 还是 x64，然后执行:
../%{JS: Util.asciify("_%{Env:ARCH}-%{ActiveProjectBuildConfig:Type}")}

Or you could set an environment variable with your architecture, be it x86 or x64, and do:
../%{JS: Util.asciify("_%{Env:ARCH}-%{ActiveProjectBuildConfig:Type}")}

JS 是一个特殊的变量，支持表达式求值.
这是官方文档:

这个答案提供了 Qt Creator 公开的函数列表:https://stackoverflow.com/a/43763489/10996546

JS is a special variable that enables expression evaluation.
