Very simple config file reading.

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.

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
