According to this pattern, once the component has been installed, the -installation deploys default values in @code{$@{prefix@}/share/taler/config.d/}, in -@emph{.conf} files. In order to override these defaults, the user can write a custom -@emph{.conf} file and either pass it to the component at execution time, or name it -@code{taler.conf} and place it under @code{$HOME/.config/}. - -A config file is a text file containing `sections`, and each section contains -its `values`. The right format follows:: - -@smallexample -[section1] -value1 = string -value2 = 23 - -[section2] -value21 = string -value22 = /path22 -@end smallexample - -Throughout any configuration file, it is possible to use @emph{$}-prefixed variables, -like @code{$VAR}, especially when they represent filesystem paths. -It is also possible to provide defaults values for those variables that are unset, -by using the following syntax: @code{$@{VAR:-default@}}. -However, there are two ways a user can set @emph{$}-prefixable variables: - -by defining them under a @code{[paths]} section, see example below, - -@smallexample -[paths] -TALER_DEPLOYMENT_SHARED = ${HOME}/shared-data -.. -[section-x] -path-x = ${TALER_DEPLOYMENT_SHARED}/x -@end smallexample - -or by setting them in the environment - -@smallexample -$ export VAR=/x -@end smallexample - -The configuration loader will give precedence to variables set under @code{[path]}, -though. - -The utility @code{taler-config}, which gets installed along with the exchange, -serves to get and set configuration values without directly editing the @emph{.conf}. -The option @code{-f} is particularly useful to resolve pathnames, when they use -several levels of @emph{$}-expanded variables. See @code{taler-config --help}. - -Note that, in this stage of development, the file @code{$HOME/.config/taler.conf} -can contain sections for @emph{all} the component. For example, both an exchange and -a bank can read values from it. - -The repository @emph{git://taler.net/deployment} contains examples of configuration -file used in our demos. See under @code{deployment/config}. - -Expectably, some components will not work just by using default values, as their -work is often interdependent. For example, a merchant needs to know an exchange -URL, or a database name. - - @node Deployment @chapter Deployment
