- Generators
-
-
- Generators are functions that create file formats from nix data structures,
- e. g. for configuration files. There are generators available for:
- INI, JSON and YAML
-
-
-
- All generators follow a similar call interface: generatorName
- configFunctions data
, where configFunctions is an
- attrset of user-defined functions that format nested parts of the content.
- They each have common defaults, so often they do not need to be set
- manually. An example is mkSectionName ? (name: libStr.escape [ "[" "]"
- ] name)
from the INI generator. It receives the
- name of a section and sanitizes it. The default
- mkSectionName escapes [ and
- ] with a backslash.
-
-
-
- Generators can be fine-tuned to produce exactly the file format required by
- your application/service. One example is an INI-file format which uses
- : as separator, the strings
- "yes"/"no" as boolean values and
- requires all string values to be quoted:
-
-
-
-with lib;
-let
- customToINI = generators.toINI {
- # specifies how to format a key/value pair
- mkKeyValue = generators.mkKeyValueDefault {
- # specifies the generated string for a subset of nix values
- mkValueString = v:
- if v == true then ''"yes"''
- else if v == false then ''"no"''
- else if isString v then ''"${v}"''
- # and delegats all other values to the default generator
- else generators.mkValueStringDefault {} v;
- } ":";
- };
-
-# the INI file can now be given as plain old nix values
-in customToINI {
- main = {
- pushinfo = true;
- autopush = false;
- host = "localhost";
- port = 42;
- };
- mergetool = {
- merge = "diff3";
- };
-}
-
-
-
- This will produce the following INI file as nix string:
-
-
-
-[main]
-autopush:"no"
-host:"localhost"
-port:42
-pushinfo:"yes"
-str\:ange:"very::strange"
-
-[mergetool]
-merge:"diff3"
-
-
-
-
- Nix store paths can be converted to strings by enclosing a derivation
- attribute like so: "${drv}"
.

-
-
- Detailed documentation for each generator can be found in
- lib/generators.nix.
