2017-06-07Don't show flags from config settings in "nix --help"Eelco Dolstra
2017-06-07nix: Add --help-config flagEelco Dolstra
2017-06-07nix: Make all options available as flagsEelco Dolstra
Thus, instead of ‘--option <name> <value>’, you can write ‘--<name> <value>’. So --option http-connections 100 becomes --http-connections 100 Apart from brevity, the difference is that it's not an error to set a non-existent option via --option, but unrecognized arguments are fatal. Boolean options have special treatment: they're mapped to the argument-less flags ‘--<name>’ and ‘--no-<name>’. E.g. --option auto-optimise-store false becomes --no-auto-optimise-store

2017-04-20Improve nix show-config --jsonEelco Dolstra
In particular, show descriptions. This could be used for manpage generation etc.
2017-04-20Setting: Remove "Tag" template argumentEelco Dolstra
2017-04-20Read per-user settings from ~/.config/nix/nix.confEelco Dolstra
2017-04-13Convert Settings to the new config systemEelco Dolstra
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13Add a Config class to simplify adding configuration settingsEelco Dolstra
The typical use is to inherit Config and add Setting<T> members: class MyClass : private Config { Setting<int> foo{this, 123, "foo", "the number of foos to use"}; Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"}; MyClass() : Config(readConfigFile("/etc/my-app.conf")) { std::cout << foo << "\n"; // will print 123 unless overriden } }; Currently, this is used by Store and its subclasses for store parameters. You now get a warning if you specify a non-existant store parameter in a store URI.
