A configuration file handler for the most basic stuff in ini files that will get you up and running in no time.
pyconfigreader's `ConfigReader` uses Python's ConfigParser to parse config files.
***PS***: This is just to get you working on other stuff and not focus on config files.
If you need advanced features head to [Python's ConfigParser](https://docs.python.org/3/library/configparser.html) or
read [pyconfigreader's documentation](https://pyconfigreader.readthedocs.io/).
# Usage
## Installation
```
$ pip install pyconfigreader
```
## Setting Values
`ConfigReader` creates a default `main` section in which key-value pairs are inserted if no section is specified.
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('version', '2') # Saved to section `main`
config.set('Key', 'Value', section='Section') # Creates a section `Section` on-the-fly
config.set('name', 'main')
config.close(save=True) # Save on close
# Or explicitly call
# config.save()
# config.close()
```
By default, changes are not immediately written to the file on disk but are kept in memory.
`commit=True` writes the changes to the file on disk.
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('okay', 'True', commit=True)
```
## Getting values
Getting values only requires specifying the key. If the key does not exist then None is returned. No exception is raised.
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
name = config.get('name')
okay = config.get('okay')
section = config.get('Key', section='Section') # Get from the section `Section`
agency = config.get('agency') # Raises NoOptionError
print(config.sections) # Get a list of sections
key, value, section = config.search('config') # Search for the parameters of a value. Returns a tuple
help(config)
config.close() # Don't forget to close the file object
```
Sometimes, if a key is not available a return value may be added using the `default` argument
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
name = config.get('country', default='Kenya') # Returns Kenya since key was not available in config file
config.close()
```
The return value, by default, is not saved to file but this can be enabled by
setting `default_commit`=True
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
name = config.get('name', default='Kenya', default_commit=True)
config.close()
```
Any call to `commit` saves all the in-memory changes to the file on disk.
## Options
Options can be remove permanently
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.remove_option('reader') # the reader option is always set by default
# or config.remove_key('reader')
config.set('name', 'first', section='Details')
config.remove_option('name', section='Details')
config.close(save=True)
```
## Sections
Sections are created when keys and values are added to them.
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('name', 'first', section='Details') # Save key `name` with value `first` in section `Details`
config.close()
```
Sections can be removed explicitly.
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('name', 'first', section='Details') # Creates section `Details`
config.remove_section('Details') # Removes section `Details` plus all the keys and values
config.close(save=True)
```
Section items can be acquired as dictionary values
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('name', 'first', section='Details')
config.get_items('Details')
# OrderedDict([('name', 'first')])
config.close() # Or config.close(save=True)
```
## Environment Variables
Configuration values can be save to the environment (`os.environ`)
```python
import os
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('name', 'first', section='Details')
config.to_env()
os.environ['DETAILS_NAME']
# first
os.environ['MAIN_READER']
# configreader
config.close()
```
The environment keys are formed from the section name and the key name.
## Saving
Changes are not written to disk unless `commit` is set to True.
Another alternative is calling `to_file`
```python
from pyconfigreader import ConfigReader
config = ConfigReader(filename='config.ini')
config.set('name', 'first', section='Details')
config.save()
config.close()
```
As a context, the changes are saved when the object is closed.
```python
from pyconfigreader import ConfigReader
with ConfigReader(filename='config.ini') as config:
config.set('name', 'first', section='Details')
```
The contents of the config file can also be dumped to a JSON file.
```python
from pyconfigreader import ConfigReader
reader = ConfigReader()
reader.set('name', 'first', section='Details')
with open('config.json', 'w') as f:
reader.to_json(f)
reader.close()
```
A lot more on `help(config)`
