# MakeupPrisma
|
||||
|
||||
A [Makeup](https://github.com/elixir-makeup/makeup/) lexer for Prisma.
|
||||
|
||||
## Installation
|
||||
|
||||
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
|
||||
by adding `makeup_prisma` to your list of dependencies in `mix.exs`:
|
||||
|
||||
```elixir
|
||||
def deps do
|
||||
[
|
||||
{:makeup_prisma, "~> 0.1.0"}
|
||||
]
|
||||
end
|
||||
```
|
||||
|
||||
Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
|
||||
and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
|
||||
be found at <https://hexdocs.pm/makeup_prisma>.
|
||||
|
||||
MakeupPrisma is derived from [MakeupGraphql](https://github.com/Billzabob/makeup_graphql).
