Synopsis
Very simple config file reading (Haskell)
Description
This package contains modules for runtime reading of very simple
config files of the key=value style or as a Haskell data structure
to be deserialized with Read. The modules support files with
blank lines and simple single-line comments, but nothing else.
KVConf
Pros
- Well-known
key=value config file syntax
- Adding new entries doesn’t necessarily mean code changes as they
are stored in a Map
Cons
- All values are
String and so may as well be untyped. Conversion
to other types will be required by users of the library.
- Simulating hierarchies requires hacky key syntax with dots or
what-have-you
- Only single-line comments supported at this time, with #
- No support for INI sections or variable substitution
ReadConf
Pros
- Config files are strongly typed Haskell source code.
Read
instancing takes care of everything!
- Can easily support hierarchical data because Haskell data types
do so
Cons
- Config files must adhere to Haskell source syntax (may not be a
con for some)
- Changing the config file at all requires code changes to keep
the types synced with each other.
- Only single-line comments supported at this time, with –
- No support for variable substitution
Getting source
- Get the source with darcs:
$ darcs get http://hub.darcs.net/dino/tce-conf
- If you’re just looking, browse the source
And once you have it, building the usual way:
$ stack build
$ stack test
