我有 python 脚本,它正在更新文件中的变量值,变量值是当前被编码的,但它们将在运行时使用命令行参数传递。我的代码如下:
import subprocess
import time
import sys
import string
from optparse import OptionParser
from optparse import OptionGroup
def main():
usage = "usage: %prog [options]"
parser = OptionParser()
try:
parser = parse_options(parser)
(options, args) = parser.parse_args()
except SystemExit:
return 0
myfile = open('over.tex','r')
data = myfile.readlines()
myfile.close()
val = time.strftime("%d/%m/%Y")
for i in range(len(data)):
test_dict = dict( var_Title = "ABC doc"
, var_Doc = "136"
, var_ECN = "XXXX"
, var_date = time.strftime("%d/%m/%Y")
, var_ProjectName= str(options.project_name)
, var_version = str(options.version) )
test_tuple = ( 'var_Title'
, 'var_Doc'
, 'var_Rev'
, 'var_ECN'
, 'var_date'
, 'var_ProjectName'
, 'var_version'
)
for key in test_tuple:
print test_dict[key]
data[i] = data[i].replace((key), (test_dict[key]))
with open('over.tex', 'w') as file:
file.writelines( data)
if options.project_name:
var = "WELCOME"
if options.version:
print "1.1"
def parse_options(parser):
group = OptionGroup(parser, "Target options","CMake Target properties")
group.add_option("", "--project_name", action="store_true",default=False,dest="project_name",help="Project name")
group.add_option("", "--version", action="store_true",default=False,dest="version",help="Version")
parser.add_option_group(group)
return parser
if __name__ == "__main__":
main()
现在你可以看到我正在使用 option.parser 将值传递给“var_ProjectName”和“var_version”,但是当我在命令行上执行它时:
myscript.py --project_name --version
在针对变量 Project_name 和 Project_version 的文件中,我得到如下内容:
Project_name = True
Project_version = True
但这不是我想要的。我想要如下:
Project_name = WELCOME
Project_version = 1.1
那么,请帮助我怎样才能拥有它,我做错了什么?我只想将值从 comandilne 参数传递给所有变量,所以最初我只尝试使用两个变量(project_name 和 version)。
