# Template syntax

Translations are defined in a TSV file. The first column is the key (used as the OCaml function name). The following columns are the translations for each language, in the order specified by the `--languages` option.


## Simple strings

```
foo	This is a simple key.	Ceci est une clé toute simple.
```

## Variables

`{{x}}` defines a labelled argument `~x`:

```
bar	I am {{x}}.	Je suis {{x}}.
```

## Typed variables

`{{x %d}}` defines a labelled argument `~x` with a format specifier:

```
bu	I am {{x %s}} ({{n %d}}).	Je suis {{x %s}} ({{n %d}}).
```

## Conditional values

`{{{c?if_true||if_false}}}` defines an optional boolean argument `?(c=false)`.

```
baz	There {{{c?are||is}}} apple{{{c?s||}}} here!	Il y a {{{c?des||une}}} pomme{{{c?s||}}} ici !
```

## Notes

- Languages do not need to use the same variables. The compiler generates a function taking all parameters it detects across all languages.
- A variable name used twice refers to the same argument.
- The TSV file must end with a newline.
