* encoder_lua: Handle explicitly positive infinity * encoder_lua: Fix inclusion of pre-/suffix when prettyPrinted It seems certain operations like --prettyPrint or subset selections does not produce a DocumentNode, which is where the lua pre- and suffix was printed, causing those to be omitted. * encoder_lua: Improve Tag handling robustness Using the method call seems more reliable in case the input parser forgets to set the tag.

## Basic input example
|
|
Given a sample.lua file of:
|
|
```lua
|
|
return {
|
|
["country"] = "Australia"; -- this place
|
|
["cities"] = {
|
|
"Sydney",
|
|
"Melbourne",
|
|
"Brisbane",
|
|
"Perth",
|
|
};
|
|
};
|
|
|
|
```
|
|
then
|
|
```bash
|
|
yq -oy '.' sample.lua
|
|
```
|
|
will output
|
|
```yaml
|
|
country: Australia
|
|
cities:
|
|
- Sydney
|
|
- Melbourne
|
|
- Brisbane
|
|
- Perth
|
|
```
|
|
|
|
## Basic output example
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
---
|
|
country: Australia # this place
|
|
cities:
|
|
- Sydney
|
|
- Melbourne
|
|
- Brisbane
|
|
- Perth
|
|
```
|
|
then
|
|
```bash
|
|
yq -o=lua '.' sample.yml
|
|
```
|
|
will output
|
|
```lua
|
|
return {
|
|
["country"] = "Australia"; -- this place
|
|
["cities"] = {
|
|
"Sydney",
|
|
"Melbourne",
|
|
"Brisbane",
|
|
"Perth",
|
|
};
|
|
};
|
|
```
|
|
|
|
## Unquoted keys
|
|
Uses the `--lua-unquoted` option to produce a nicer-looking output.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
---
|
|
country: Australia # this place
|
|
cities:
|
|
- Sydney
|
|
- Melbourne
|
|
- Brisbane
|
|
- Perth
|
|
```
|
|
then
|
|
```bash
|
|
yq -o=lua --lua-unquoted '.' sample.yml
|
|
```
|
|
will output
|
|
```lua
|
|
return {
|
|
country = "Australia"; -- this place
|
|
cities = {
|
|
"Sydney",
|
|
"Melbourne",
|
|
"Brisbane",
|
|
"Perth",
|
|
};
|
|
};
|
|
```
|
|
|
|
## Globals
|
|
Uses the `--lua-globals` option to export the values into the global scope.
|
|
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
---
|
|
country: Australia # this place
|
|
cities:
|
|
- Sydney
|
|
- Melbourne
|
|
- Brisbane
|
|
- Perth
|
|
```
|
|
then
|
|
```bash
|
|
yq -o=lua --lua-globals '.' sample.yml
|
|
```
|
|
will output
|
|
```lua
|
|
country = "Australia"; -- this place
|
|
cities = {
|
|
"Sydney",
|
|
"Melbourne",
|
|
"Brisbane",
|
|
"Perth",
|
|
};
|
|
```

## Elaborate example
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
---
|
|
hello: world
|
|
tables:
|
|
like: this
|
|
keys: values
|
|
? look: non-string keys
|
|
: True
|
|
numbers:
|
|
- decimal: 12345
|
|
- hex: 0x7fabc123
|
|
- octal: 0o30
|
|
- float: 123.45
|
|
- infinity: .inf
|
|
plus_infinity: +.inf
|
|
minus_infinity: -.inf
|
|
- not: .nan
|
|
|
|
```
|
|
then
|
|
```bash
|
|
yq -o=lua '.' sample.yml
|
|
```
|
|
will output
|
|
```lua
|
|
return {
|
|
["hello"] = "world";
|
|
["tables"] = {

["numbers"] = {

|
["hex"] = 0x7fabc123;
|

},
|
|
{
|
|
["octal"] = 24;
|
|
},
|
|
{
|
|
["float"] = 123.45;
|
|
},
|
|
{
|
|
["infinity"] = (1/0);
|
|
["plus_infinity"] = (1/0);
|

},
|
