Updating section in ConfigParser (or an alternative)
I am making a plugin for another program and so I am trying to make thing as lightweight as possible.
What i need to do is be able to update the name of a section in the ConfigParser's config file.
[project name]
author:john doe
email: spam@example.com
year: 2010
I then have text fields where user can edit project's name, author, email and year.
I don't think changing [project name] is possible, so I have thought of two solutions:
1 -Have my config file like this:
[0]
projectname: foobar
author:john doe
email: spam@example.com
year: 2010
that way i can change project's name just like another option. But the problem is, i would need the section # to be auto incremented ([0], [1], etc). And to do this i would have to get every se开发者_运维技巧ction, sort of, and figure out what the next number should be.
The other option would be to delete the entire section and its value, and re-add it with the updated values which would require a little more work as well, such as passing a variable that holds the old section name through functions, etc, but i wouldn't mind if it's faster.
Which of the two is best? or is there another way? I am willing to go with the fastest/lightweight solution possible, doesn't matter if it requires more work or not.
ini files are probably best suited for configuring applications, with well-defined inputs and so forth. It sounds like you want a more generic serialization tool; JSON would probably work well for this. Perhaps you want to store a JSON representation of a list (hence your incrementing indices) of dicts with those fields?
The usage of the json
module in the stdlib is pretty simple. For example, to store a couple records you would
import json
projects = []
projects.append({'project_name': 'foobar',
'author': 'John Doe',
'email': 'spam@example.com',
'year': '2010'})
projects.append({'project_name': 'baz',
'author': 'Cat Stevens',
'email': 'cs@example.com',
'year': '2009'})
with open('projects.json', 'w') as f:
json.dump(projects, f)
Similarly you would recover the serialized data from the file with json.load(f)
, where you have opened f
in read mode.
