我有这个脚本允许用户通过参数输入文件名,然后更新文件版本:
#!/usr/bin/env python
import os
import sys
class versionBumper:
def __init__(self):
self.version = None
self.SavedBefore = ""
self.SavedAfter = ""
def change_version(self, file_to_be_modded, packageVersion):
for line in file_to_be_modded:
if packageVersion in line:
print "VERSION FOUND: ", line
self.VersionNumber = line
elif self.VersionNumber is None:
self.SavedBefore += line
else:
self.SavedAfter += line
file_to_be_modded.close()
print "Version: ", self.VersionNumber
return self.VersionNumber
if __name__ == '__main__':
print "sys.argv[1:]:", sys.argv[0:]
versionBumper123 = versionBumper()
filename = sys.argv[1]
path = "/home/Desktop/Crate/Crate/" + filename + "/build/CMakeLists.txt"
if os.path.exists:
inputFile = open(path, 'r')
else:
print "no match found"
sys.exit()
print "Which version number to bump ?"
print "1) major"
print "2) minor."
print "3) patch."
Choose_version = raw_input("Choose version: ")
if Choose_version == "1":
version = versionBumper123.change_version(inputFile, "_MAJOR ")
elif Choose_version == "2":
version = versionBumper123.change_version(inputFile, "_MINOR ")
elif Choose_version == "3":
version = versionBumper123.change_version(inputFile, "_PATCH ")
else:
print "Invalid input. Exiting gracefully..."
sys.exit()
outputFile = open (path, 'w')
splitted_version_line_substrings = version.split('"')
Version_Name = splitted_version_line_substrings[0]
Version_Number = int(splitted_version_line_substrings[1]) + 1
parenthesis = splitted_version_line_substrings[2]
new_version = (str(Version_Name) + '"'
+ str(Version_Number) + '"'
+ str(parenthesis))
print "new_version: ", new_version
outputFile.write(str(versionBumper123.SavedBefore))
outputFile.write(str(new_version))
outputFile.write(str(versionBumper123.SavedAfter))
但我一直收到这个错误:
Traceback (most recent call last):
File "untitled.py", line 57, in <module>
splitted_version_line_substrings = version.split('"')
NameError: name 'version' is not defined.
我还尝试将version
定义为全局变量,但也没有用,我无法弄清楚如何从定义的函数外部调用version
。
答案 0 :(得分:0)
我认为您正在处理班级versionBumper
versionBumper123 = versionBumper()
所以我猜你要用语句做什么
splitted_version_line_substrings = version.split('"')
应表示为
splitted_version_line_substrings = versionBumper123.version.split('"')
仅仅因为您使用了类的单个实例,如果您不使用类,则可以编写更简单的代码。
