使用bash提取python文件的代码并从中提取值。
提问于 2022-09-15 17:53:35
我有一个setup.py文件，如下所示：
#!/usr/bin/env python
DIR = Path(__file__).parent
README = (DIR / "README.md").read_text()
install_reqs = parse_requirements(DIR / "requirements.txt")
try:
dev_reqs = parse_requirements(DIR / "requirements-dev.txt")
except FileNotFoundError:
dev_reqs = {}
print("INFO: Could not find dev and/or prepro requirements txt file.")
if __name__ == "__main__":
setup(
keywords=[
"demo"
],
python_requires=">=3.7",
install_requires=install_reqs,
extras_require={"dev": dev_reqs},
entry_points={
"console_scripts": ["main=smamesdemo.run.main:main"]
},
)我希望在文件夹中递归地找到这个文件，并解压以下部分：
entry_points={
"console_scripts": ["main=smamesdemo.run.main:main"]
},它也可能像这样
entry_points={"console_scripts": ["main=smamesdemo.run.main:main"]}所需的：我想检查该入口点字典是否包含一个以main名称开头并返回True或False (或抛出错误)的脚本的console_scripts部分。
我会找到文件和所需的值，如下所示：
grep -rnw "./" -e "entry_points"这将返回以下内容：
./setup.py:22: entry_points={有人知道怎么解决这个问题吗？

假设在setup.py文件中只有一个entry_points={...}块，其语法与示例中所述的语法相同。
- 下面的脚本将通过提供请求的输出在当前目录中找到
setup.py文件.
#!/bin/bash
directory_to_find='.' # Directory path to find the "${py_script}" file.
py_script="setup.py" # Python script file name.
dictionary_to_match="console_scripts" # Dictionary to match
dictionary_script_to_match="main" # Script name to match - If the Dictionary found.
########################################################
py_script=$(find "${directory_to_find}" -name "${py_script}" -type f)
found_entrypoint=$(
while IFS='' read -r line ;do
echo -n $line
done <<< $(fgrep -A1 'entry_points={' ${py_script})
echo -n '}' && echo ""
)
found_entrypoint_dictionary=$(echo ${found_entrypoint} | awk -F'{' '{print $2}' | awk -F':' '{print $1}')
found_entrypoint_dictionary=$(echo ${found_entrypoint_dictionary//\"/})
found_dictionary_script=$(echo ${found_entrypoint} | awk -F'[' '{print $2}' | awk -F'=' '{print $1}')
found_dictionary_script=$(echo ${found_dictionary_script//\"/})
if ! [[ "${found_entrypoint}" =~ ^entry_points\=\{.* ]] ;then
echo "entry_points not found."
exit 1

if [ "${found_entrypoint_dictionary}" == "${dictionary_to_match}" ] && [ "${found_dictionary_script}" == "${dictionary_script_to_match}" ] ;then
echo "${found_entrypoint}"
echo "True"
elif [ "${found_entrypoint_dictionary}" != "${dictionary_to_match}" ] || [ "${found_dictionary_script}" != "${dictionary_script_to_match}" ] ;then
echo "${found_entrypoint}"
echo "False"
else
echo "Somthing went wrong!"
