Enable variables in a TOML file
Project description
Overview
vartoml
allows using variables in TOML config files. It uses the toml
package.
Acknowledgent
The idea how to tackle the problem of variable interpolation was taken
from the envtoml
package which is at https://github.com/mrshu/envtoml .
Variable names in TOML file
Variables are specified this way: ${section[:section]:variable}
, i.e. sections can be nested.
Example usage
from vartoml import VarToml
TOML ="""
[default]
basedir = "/myproject"
bindir = "${default:basedir}/bin"
datadir = "${default:basedir}/data"
[other_dirs-sub]
logdir = "${default:datadir}/logs"
"""
toml = VarToml()
toml.loads(TOML)
assert toml.get('other_dirs-sub', 'logdir') == '/myproject/data/logs'
API
VarToml.load(f, _dict=dict)
same like what the toml package offers
VarToml.loads(s, _dict=dict)
same like what the toml package offers
VarToml.get(v,... )
returns a specific value from the toml dictionary
Example:
```python
toml = VarToml()
toml.loads('some.toml')
val = toml.get('default', 'id' )
```
VarToml.toml()
returns the dictionary of the parsed toml data
