Project description
config-enhance adds re-use capabilities to ConfigParser style config files.
It introduces a reserved key: '<<='
The '<<=' key should be assigned a list of enhancements like:
[section]
<<=
<other1
+other2
<other3
-other4
Each enhancement is composed of an operator followed by a section name. The operators are:
- '<' : mix things in from another section if they don't already exist
- '+' : pull config from another section, overwrite settings in the current section
if there is a clash.
- '-' : remove config items that exist in the source section from this section
You can use it like this:
from config_enhance import enhance
cp = ConfigParser (file ("my.cfg"))
enhance(cp)
Suppose that my.cfg contains content like:
[common]
flup = 1.0
requests = 2.0
[tes_100]
<<= <common
requests = 5.0
tornado = 6.0
[dev_tes_common]
tornado = 6.0d
[dev_unpin]
flup = unpin
[dev_tes_100]
<<=
<tes_100
+dev_tes_common
-dev_unpin
After running enhance, 'cp' will be modified to contain:
[common]
flup = 1.0
requests = 2.0
[tes_100]
flup = 1.0
requests = 5.0
tornado = 6.0
[dev_tes_common]
tornado = 6.0d
[dev_unpin]
flup = unpin
[dev_tes_100]
requests = 5.0
tornado = 6.0d
# target audience
config-enhance is useful when managing version requirement sections in buildout.
Buildout already contains limited reuse features through the '<=' idiom. But,
version management is easier with an extended set.
