conf -package:lens
Try to parse a configuration value at the given key.
Multiple
confs will be tried in order.
Not on Stackage, so not searched.
Parser for Haskell-based configuration files.
Read extra CLI arguments from a hledger config file.
The fixity of the constructor
Confidence interval for bootstrap estimation (greater than 0, less
than 1).
Over-ride this hook to get different behavior during configure.
Perform the "./setup configure" action. Returns the
.setup-config file.
Try to configure all the known programs that have not yet been
configured.
Try to configure a specific program and add it to the program
database.
If the program is already included in the collection of unconfigured
programs, then we use any user-supplied location and arguments. If the
program gets configured successfully, it gets added to the configured
collection.
Note that it is not a failure if the program cannot be configured.
It's only a failure if the user supplied a location and the program
could not be found at that location.
The reason for it not being a failure at this stage is that we don't
know up front all the programs we will need, so we try to configure
them all. To verify that a program was actually successfully
configured use
requireProgram.
Try to configure a specific program. If the program is already
included in the collection of unconfigured programs then we use any
user-supplied location and arguments.
List all configured programs.
Allow depending on private sublibraries. This is used by external
tools (like cabal-install) so they can add multiple-public-libraries
compatibility to older ghcs by checking visibility externally.
