tm_jsonencode Function
tm_jsonencode encodes a given value to a string using JSON syntax.
The JSON encoding is defined in RFC 7159.
This function maps Terramate language values to JSON values in the following way:
| Terramate type | JSON type |
|---|---|
string | String |
number | Number |
bool | Bool |
list(...) | Array |
set(...) | Array |
tuple(...) | Array |
map(...) | Object |
object(...) | Object |
| Null value | null |
Since the JSON format cannot fully represent all of the Terramate language types, passing the jsonencode result to jsondecode will not produce an identical value, but the automatic type conversion rules mean that this is rarely a problem in practice.
When encoding strings, this function escapes some characters using Unicode escape sequences: replacing <, >, &, U+2028, and U+2029 with \u003c, \u003e, \u0026, \u2028, and \u2029.
The jsonencode command outputs a minified representation of the input.
Examples
tm_jsonencode({"hello"="world"})
{"hello":"world"}Related Functions
tm_jsondecodeperforms the opposite operation, decoding a JSON string to obtain its represented value.
