* lib/cli: mkKey -> mkOptionName, use generators.mkValueStringDefaultProfpatsch2020-01-23
| | | | | | | | | Let’s call them by what they are, option names. `generators.mkValueStringDefault` is a better value string renderer than plain `toString`. Also add docs to all options.
* lib/cli: rename `renderX` options to `mkX`Profpatsch2020-01-23
| | | | | | | Mirrors the naming scheme in `generators.nix`, for consistency. Also rename `key` to `k` and value to `v` to aid readability to the code structure.

* lib/cli: encodeGNUCommandLine -> toGNUCommandLineShellProfpatsch2020-01-23
| | | | | | | | | | | | | | The semantic difference between `encode` and `to` is not apparent. Users are likely to confuse both functions (which leads to unexpected error messages about the wrong types). Like in `generators.nix`, all functions should be prefixed by `to`. Furthermore, converting to a string depends on the target context. In this case, it’s a POSIX shell, so we should name it that (compare `escapeShellArg` in `strings.nix`). We can later add versions that escape for embedding in e.g. python scripts or similar.

* Use a more realistic example that exercises all encodingsGabriel Gonzalez2019-12-15
| | | | | | ... as suggested by @roberth This also caught a bug in rendering lists, which this change also fixes
* Make behavior of `encodeGNUCommandLine` customizableGabriel Gonzalez2019-12-13

* Add `pkgs.lib.renderOptions`Gabriel Gonzalez2019-12-11
This adds a new utility to intelligently convert Nix records to command line options to reduce boilerplate for simple use cases and to also reduce the likelihood of malformed command lines
