According to this pattern, once the component has been installed, the -installation deploys default values in `${prefix}/share/taler/config.d/`, in -`.conf` files. In order to override these defaults, the user can write a custom -`.conf` file and either pass it to the component at execution time, or name it -`taler.conf` and place it under `$HOME/.config/`. - - --------------------- -Configuration format --------------------- - -A config file is a text file containing `sections`, and each section contains -its `values`. The right format follows:: - - [section1] - value1 = string - value2 = 23 - - [section2] - value21 = string - value22 = /path22 - -Throughout any configuration file, it is possible to use ``$``-prefixed variables, -like ``$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: ``${VAR:-default}``. -However, there are two ways a user can set ``$``-prefixable variables: - -by defining them under a ``[paths]`` section, see example below, :: - - [paths] - TALER_DEPLOYMENT_SHARED = ${HOME}/shared-data - .. - [section-x] - path-x = ${TALER_DEPLOYMENT_SHARED}/x - -or by setting them in the environment:: - - $ export VAR=/x - -The configuration loader will give precedence to variables set under ``[path]``, -though. - -The utility ``taler-config``, which gets installed along with the exchange, serves -to get and set configuration values without directly editing the `.conf`. -The option ``-f`` is particularly useful to resolve pathnames, when they use -several levels of ``$``-expanded variables. See ``taler-config --help``. - -Note that, in this stage of development, the file ``$HOME/.config/taler.conf`` -can contain sections for *all* the component. For example, both an exchange and -a bank can read values from it. - -The repository ``git://taler.net/deployment`` contains examples of configuration -file used in our demos. See under ``deployment/config``. - -.. note:: - - 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. -- cgit v1.2.3
