TOML v0.1.0 | ||
=========== | ||
|
||
Tom's Obvious, Minimal Language. | ||
|
||
By Tom Preston-Werner. | ||
|
||
Be warned, this spec is still changing a lot. Until it's marked as 1.0, you | ||
should assume that it is unstable and act accordingly. | ||
|
||
Objectives | ||
---------- | ||
|
||
TOML aims to be a minimal configuration file format that's easy to read due to | ||
obvious semantics. TOML is designed to map unambiguously to a hash table. TOML | ||
should be easy to parse into data structures in a wide variety of languages. | ||
|
||
Example | ||
------- | ||
|
||
```toml | ||
# This is a TOML document. Boom. | ||
|
||
title = "TOML Example" | ||
|
||
[owner] | ||
name = "Tom Preston-Werner" | ||
organization = "GitHub" | ||
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer." | ||
dob = 1979-05-27T07:32:00Z # First class dates? Why not? | ||
|
||
[database] | ||
server = "192.168.1.1" | ||
ports = [ 8001, 8001, 8002 ] | ||
connection_max = 5000 | ||
enabled = true | ||
|
||
[servers] | ||
|
||
# You can indent as you please. Tabs or spaces. TOML don't care. | ||
[servers.alpha] | ||
ip = "10.0.0.1" | ||
dc = "eqdc10" | ||
|
||
[servers.beta] | ||
ip = "10.0.0.2" | ||
dc = "eqdc10" | ||
|
||
[clients] | ||
data = [ ["gamma", "delta"], [1, 2] ] | ||
|
||
# Line breaks are OK when inside arrays | ||
hosts = [ | ||
"alpha", | ||
"omega" | ||
] | ||
``` | ||
|
||
Spec | ||
---- | ||
|
||
* TOML is case sensitive. | ||
* Whitespace means tab (0x09) or space (0x20). | ||
|
||
Comment | ||
------- | ||
|
||
Speak your mind with the hash symbol. They go from the symbol to the end of the | ||
line. | ||
|
||
```toml | ||
# I am a comment. Hear me roar. Roar. | ||
key = "value" # Yeah, you can do this. | ||
``` | ||
|
||
String | ||
------ | ||
|
||
ProTip™: You may notice that this specification is the same as JSON's string | ||
definition, except that TOML requires UTF-8 encoding. This is on purpose. | ||
|
||
Strings are single-line values surrounded by quotation marks. Strings must | ||
contain only valid UTF-8 characters. Any Unicode character maybe be used except | ||
those that must be escaped: quotation mark, backslash, and the control | ||
characters (U+0000 to U+001F). | ||
|
||
```toml | ||
"I'm a string. \"You can quote me\". Name\tJos\u00E9\nLocation\tSF." | ||
``` | ||
|
||
For convenience, some popular characters have a compact escape sequence. | ||
|
||
``` | ||
\b - backspace (U+0008) | ||
\t - tab (U+0009) | ||
\n - linefeed (U+000A) | ||
\f - form feed (U+000C) | ||
\r - carriage return (U+000D) | ||
\" - quote (U+0022) | ||
\/ - slash (U+002F) | ||
\\ - backslash (U+005C) | ||
\uXXXX - unicode (U+XXXX) | ||
``` | ||
|
||
Any Unicode character may be escaped with the `\uXXXX` form. | ||
|
||
Other special characters are reserved and, if used, TOML should produce an | ||
error. This means paths on Windows will always have to use double backslashes. | ||
|
||
```toml | ||
wrong = "C:\Users\nodejs\templates" # note: doesn't produce a valid path | ||
right = "C:\\Users\\nodejs\\templates" | ||
``` | ||
|
||
For binary data it is recommended that you use Base 64 or another suitable | ||
encoding. The handling of that encoding will be application specific. | ||
|
||
Integer | ||
------- | ||
|
||
Integers are bare numbers, all alone. Feeling negative? Do what's natural. | ||
64-bit minimum size expected. | ||
|
||
```toml | ||
42 | ||
-17 | ||
``` | ||
|
||
Float | ||
----- | ||
|
||
Floats are numbers with a single dot within. There must be at least one number | ||
on each side of the decimal point. 64-bit (double) precision expected. | ||
|
||
```toml | ||
3.1415 | ||
-0.01 | ||
``` | ||
|
||
Boolean | ||
------- | ||
|
||
Booleans are just the tokens you're used to. Always lowercase. | ||
|
||
```toml | ||
true | ||
false | ||
``` | ||
|
||
Datetime | ||
-------- | ||
|
||
Datetimes are ISO8601 dates, but only the full zulu form is allowed. | ||
|
||
```toml | ||
1979-05-27T07:32:00Z | ||
``` | ||
|
||
Array | ||
----- | ||
|
||
Arrays are square brackets with other primitives inside. Whitespace is ignored. | ||
Elements are separated by commas. No, you can't mix data types, that's stupid. | ||
|
||
```toml | ||
[ 1, 2, 3 ] | ||
[ "red", "yellow", "green" ] | ||
[ [ 1, 2 ], [3, 4, 5] ] | ||
[ [ 1, 2 ], ["a", "b", "c"] ] # this is ok | ||
[ 1, 2.0 ] # note: this is NOT ok | ||
``` | ||
|
||
Arrays can also be multiline. So in addition to ignoring whitespace, arrays also | ||
ignore newlines between the brackets. Terminating commas are ok before the | ||
closing bracket. | ||
|
||
```toml | ||
key = [ | ||
1, 2, 3 | ||
] | ||
|
||
key = [ | ||
1, | ||
2, # this is ok | ||
] | ||
``` | ||
|
||
Hash | ||
---- | ||
|
||
There are two ways to make keys. I call them "key groups" and "keys". Both are | ||
just regular keys, but key groups only ever have a single hash as their value. | ||
|
||
Key groups appear in square brackets on a line by themselves. You can tell them | ||
apart from arrays because arrays are only ever values. | ||
|
||
```toml | ||
[keygroup] | ||
``` | ||
|
||
Under that, and until the next key or EOF are the key/values of that key group. | ||
Keys are on the left of the equals sign and values are on the right. Keys start | ||
with the first non-whitespace character and end with the last non-whitespace | ||
character before the equals sign. Key/value pairs within key groups are | ||
unordered. | ||
|
||
```toml | ||
[keygroup] | ||
key = "value" | ||
``` | ||
|
||
You can indent keys and their values as much as you like. Tabs or spaces. Knock | ||
yourself out. Why, you ask? Because you can have nested hashes. Snap. | ||
|
||
Nested hashes are denoted by key groups with dots in them. Name your key groups | ||
whatever crap you please, just don't use a dot. Dot is reserved. OBEY. | ||
|
||
```toml | ||
[key.tater] | ||
type = "pug" | ||
``` | ||
|
||
In JSON land, that would give you the following structure. | ||
|
||
```json | ||
{ "key": { "tater": { "type": "pug" } } } | ||
``` | ||
|
||
You don't need to specify all the superkeys if you don't want to. TOML knows how | ||
to do it for you. | ||
|
||
```toml | ||
# [x] you | ||
# [x.y] don't | ||
# [x.y.z] need these | ||
[x.y.z.w] # for this to work | ||
``` | ||
|
||
When converted to a hash table, an empty key group should result in the key's | ||
value being an empty hash table. | ||
|
||
Be careful not to overwrite previous keys. That's dumb. And should produce an | ||
error. | ||
|
||
```toml | ||
# DO NOT WANT | ||
[fruit] | ||
type = "apple" | ||
|
||
[fruit.type] | ||
apple = "yes" | ||
``` | ||
|
||
Seriously? | ||
---------- | ||
|
||
Yep. | ||
|
||
But why? | ||
-------- | ||
|
||
Because we need a decent human readable format that maps to a hash and the YAML | ||
spec is like 80 pages long and gives me rage. No, JSON doesn't count. You know | ||
why. | ||
|
||
Oh god, you're right | ||
