# TOML
|
|
|
|
This module parse TOML files. It follows as much as possible the
|
|
[TOML specs](https://github.com/toml-lang/toml). Be sure to read the supported
|
|
types as not every specs is supported at the moment and the handling in
|
|
TypeScript side is a bit different.
|
|
|
|

:exclamation: _Supported with warnings see [Warning](#Warning)._
|
|
|
|
### :warning: Warning
|
|
|
|
#### String
|
|
|
|
- Regex : Due to the spec, there is no flag to detect regex properly
|
|
in a TOML declaration. So the regex is stored as string.
|
|
|
|
#### Integer
|
|
|
|
For **Binary** / **Octal** / **Hexadecimal** numbers,
|
|
they are stored as string to be not interpreted as Decimal.
|
|
|
|
#### Local Time
|
|
|
|
Because local time does not exist in JavaScript, the local time is stored as a string.
|
|
|
|
#### Inline Table
|
|
|
|
Inline tables are supported. See below:
|
|
|
|
```toml
|
|
animal = { type = { name = "pug" } }
|
|
# Output
|
|
animal = { type.name = "pug" }
|
|
# Output { animal : { type : { name : "pug" } }
|
|
animal.as.leaders = "tosin"
|
|
# Output { animal: { as: { leaders: "tosin" } } }
|
|
"tosin.abasi" = "guitarist"
|
|
# Output
|
|
"tosin.abasi" : "guitarist"
|
|
```
|
|
|
|
#### Array of Tables
|
|
|
|
At the moment only simple declarations like below are supported:
|
|
|
|
```toml
|
|
[[bin]]
|
|
name = "deno"
|
|
path = "cli/main.rs"
|
|
|
|
[[bin]]
|
|
name = "deno_core"
|
|
path = "src/foo.rs"
|
|
|
|
[[nib]]
|
|
name = "node"
|
|
path = "not_found"
|
|
```
|
|
|
|
will output:
|
|
|
|
```json
|
|
{
|
|
"bin": [
|
|
{ "name": "deno", "path": "cli/main.rs" },
|
|
{ "name": "deno_core", "path": "src/foo.rs" }
|
|
],
|
|
"nib": [{ "name": "node", "path": "not_found" }]
|
|
}
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Parse
|
|
|
|
```ts
|
|
import { parseFile, parse } from "./parser.ts";
|
|
|
|
const tomlObject = parseFile("file.toml");
|
|
|
|
const tomlString = 'foo.bar = "Deno"';
|
|
const tomlObject22 = parse(tomlString);
|
|
```
|
|
|
|
### Stringify
|
|
|
|
```ts
|
|
import { stringify } from "./parser.ts";
|
|
const obj = {
|
|
bin: [
|
|
{ name: "deno", path: "cli/main.rs" },
|
|
{ name: "deno_core", path: "src/foo.rs" }
|
|
],
|
|
nib: [{ name: "node", path: "not_found" }]
|
|
};
|
|
const tomlString = stringify(obj);
|
|
```
