Conversion and Extraction
Taplo makes it easy to convert TOML files to JSON and also extract specific values via the get
command.
Examples
The following examples use the TOML file below:
toml
# foo.toml
[foo]
bar = true
[[baz]]
baz_field = "baz 1"
[[baz]]
baz_field = "baz 2"
Converting to JSON
sh
taplo get -f foo.toml -o json
This will yield the following output:
json
{
"foo": {
"bar": true
},
"baz": [
{
"baz_field": "baz 1"
},
{
"baz_field": "baz 2"
}
]
}
Extracting Specific Values
It is possible to extract specific values via a simple query expressions.
sh
taplo get -f foo.toml 'baz[1].baz_field'
This will yield:
baz 2
WARNING
Expressions with array patterns []
might need to be put between quotation marks for some shells.
INFO
List indexing is 0-based.
By default the value will be "parsed", so that no strings will contain escape sequences or quotation marks.
However it is also possible to change the output format to JSON:
sh
taplo get -f foo.toml -o json baz
will yield:
json
[
{
"baz_field": "baz 1"
},
{
"baz_field": "baz 2"
}
]
More Examples
More examples for query expressions using the same document above:
expression | output format | output |
---|---|---|
baz.0.baz_field | json | "baz 1" |
baz.*.baz_field | json | [ "baz 1", "baz 2" ] |
baz.1.baz_field | value | baz 2 |
baz.1 | toml | baz_field = "baz 2" |
INFO
The outputs have been slightly modified to fit into the table format.
