.bzl的flattened_conditional_defines

在.bzl文件中,"flattened_conditional_defines" 是指一种处理条件宏定义的方法。在构建系统中,我们经常使用条件宏定义来控制代码的编译和行为。但是,有时这些条件宏定义会变得复杂,嵌套层级较多,使得代码难以理解和维护。
为了简化这种情况,可以使用"flattened_conditional_defines"方法来将嵌套的条件宏定义展开,并将其转换为扁平的形式。这样做可以减少代码中的嵌套,并使条件逻辑更加清晰和易于理解。
通过使用"flattened_conditional_defines",我们可以将复杂的条件宏定义转化为一系列简单的宏定义,以实现更好的代码可读性和可维护性。

import os, glob if __name__ == '__main__': txt_list = glob.glob("E:/bzl_online_dataset/2020-07-20/imgs/*.txt") for txt_item in txt_list: with open(txt_item) as f: lines = f.readlines() with open(txt_item, 'w') as f: for line in lines: line_split = line.strip().split() line_split[0] = '0' f.write( line_split[0] + ' ' + line_split[1] + " " + line_split[2] + " " + line_split[3] + " " + line_split[4]+'\n') pass
这段代码的作用是将指定文件夹下的所有txt文件中第一列的数字替换成0,并保存到原文件中。其中,使用了glob.glob函数获取指定文件夹下所有的txt文件路径,然后使用with语句打开文件进行读取和写入操作。读取时使用了readlines函数,将文件内容存储到lines变量中;写入时使用了write函数,将修改后的行重新写入到文件中。
unrecognized module type "android_app_import"
The error message "unrecognized module type 'android_app_import'" usually occurs when you are trying to import an Android library or module into your project using the `android_app_import` rule in a Bazel build file, but Bazel cannot recognize this module type.
One possible reason for this error is that the `android_app_import` rule is not defined in your WORKSPACE file or in any of the external repositories that you have included in your build. You can try adding the following lines to your WORKSPACE file to define the `android_app_import` rule:
```
load("@bazel_tools//tools/build_defs/repo:android.bzl", "android_app_import")
```
If this does not solve the problem, you may need to check if the Android module that you are trying to import is properly configured and whether it has any dependencies that are not being resolved correctly.
