Is there an easy way to read the values from a toml file?

I’m using otoml , the library allow you to read the values directly from the toml document, but does not provide any high level function for parsing a whole configuration file (like declaring a field as mandatory, transforming a table into an OCaml record and so one). For that, I’m using decoders , w…

Please, if you’re writing a new application, consider a nicer configuration format - like JSON5 . I’m working (on/off) on a JSON5 parser. But dhall would be even cooler - I am thinking of writing a parser for that, unless someone else has already started? – Ian

[image] nobrowser: consider a nicer configuration format I completely agree, I try to only use scfg nowadays (disclaimer: I wrote the OCaml implementation). But if you have to stick with toml, I recommend ez_toml .

Thank you for that information I looked at ez_toml and searched for an example without success. There is example code for scfg. I would simply like to read a simple config file and save its values in variables. In golang it’s one line of code and I was hoping it would be just as easy in ocaml. …

Did you file an example in the ez_toml repo asking for examples? Edit: sorry I mean ‘did you file an issue’

I am not sure if this is a good example, but here is a composition over ez_toml: We define first some kind of abstract idea of a configuration file with sections and options: superbol-studio-oss/src/lsp/ezr_toml/ezr_toml.ml at 9dc319fc9d680d506de21fa5297aac8eda5c7d03 · OCamlPro/superbol-studio-…

I forgot to say, but the main advantage of ez_toml over other implementation of TOML in OCaml is that it also manages comments in the file.

FWIW, I updated the README.md with an example similar to the one in OToml: GitHub - OCamlPro/ez_toml: A library to parse and print TOML files
