ada-toml: TOML parser for Ada | ||
============================= | ||
`ada-toml` is a pure Ada library for parsing and creating | ||
[TOML](https://github.com/toml-lang/toml#toml) documents. It conforms to the | ||
[version 1.0.0](https://toml.io/en/v1.0.0) of the format standard. | ||
Quick tutorial | ||
-------------- | ||
All basic types and subprograms are in the `TOML` package. All "nodes" in a | ||
TOML documents are materialized using the `TOML.TOML_Value` type. Since TOML | ||
values make up a tree, this type has reference semantics. This means that | ||
modifying a TOML node does not modify the corresponding `TOML_Value` value | ||
itself, but rather the TOML value that is referenced. | ||
Parsing a TOML file is as easy as using the `TOML.File_IO.Load_File` function: | ||
```ada | ||
declare | ||
Result : constant TOML.Read_Result := | ||
TOML.File_IO.Load_File ("config.toml"); | ||
begin | ||
if Result.Success then | ||
Ada.Text_IO.Put_Line ("config.toml loaded with success!"); | ||
else | ||
Ada.Text_IO.Put_Line ("error while loading config.toml:"); | ||
Ada.Text_IO.Put_Line | ||
(Ada.Strings.Unbounded.To_String (Result.Message)); | ||
end if; | ||
end; | ||
``` | ||
Each TOML value has kind, defining which data it contains (a boolean, an | ||
integer, a string, a table, ...). To each kind, one or several primitives are | ||
associated to let one process the underlying data: | ||
```ada | ||
case Result.Kind is | ||
when TOML.TOML_Boolean => | ||
Ada.Text_IO.Put_Line ("Boolean: " & Result.As_Boolean'Image); | ||
when TOML.TOML_Integer => | ||
Ada.Text_IO.Put_Line ("Boolean: " & Result.As_Integer'Image); | ||
when TOML.TOML_String => | ||
Ada.Text_IO.Put_Line ("Boolean: " & Result.As_String); | ||
when TOML.TOML_Array => | ||
Ada.Text_IO.Put_Line ("Array of " & Result.Length & " elements"); | ||
when others => | ||
null; | ||
end case; | ||
``` | ||
There are also primitives to build TOML values: | ||
```ada | ||
declare | ||
Bool : constant TOML.TOML_Value := TOML.Create_Boolean (False); | ||
Int : constant TOML.TOML_Value := TOML.Create_Integer (10); | ||
Str : constant TOML.TOML_Value := TOML.Create_String ("Hello, world"); | ||
Table : constant TOML.TOML_Value := TOML.Create_Table; | ||
begin | ||
Table.Set ("bool_field", Bool); | ||
Table.Set ("int_field", Int); | ||
Table.Set ("str_field", Str); | ||
end; | ||
``` | ||
And finally one can turn a tree of TOML nodes back in text form: | ||
```ada | ||
Ada.Text_IO.Put_Line ("TOML document:"); | ||
Ada.Text_IO.Put_Line (Table.Dump_As_String); | ||
``` | ||
