# Xler
|
||||||
|
|
||||||
|
Xler uses the Calamine Rust library to get contents of Excel files.
|
||||||
|
|
||||||
|
**Calamine supports:**
|
||||||
|
|
||||||
|
- excel (xls, xlsx, xlsm, xlsb, xla, xlam)
|
||||||
|
- opendocument spreadsheets (ods)
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
|
||||||
|
by adding `xler` to your list of dependencies in `mix.exs`:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
def deps do
|
||||||
|
[
|
||||||
|
{:xler, "~> 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/xler](https://hexdocs.pm/xler).
|
||||||
|
|
||||||
|
## Worksheets
|
||||||
|
|
||||||
|
To get the worksheets of a file you use:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
Xler.worksheets("filename.xls")
|
||||||
|
```
|
||||||
|
|
||||||
|
and it will return as a tuple:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
{:ok, ["Sheet 1"]}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Parse
|
||||||
|
|
||||||
|
To get the data of a worksheet you use:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
Xler.parse("filename.xls", "Sheet 1")
|
||||||
|
```
|
||||||
|
|
||||||
|
and it will return as a tuple:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
{:ok, [["Date", "Time"]]}
|
||||||
|
```

# Application.get_env(:xler, :key)

#
|

# config :logger, level: :info

#
|
||||||

|
||||||
|
# directory. For example, you can emulate configuration per environment
|
||||||
|
# by uncommenting the line below and defining dev.exs, test.exs and such.
|
||||||
|
# Configuration from the imported file will override the ones defined
|
||||||
|
# here (which is why it is important to import them last).
|

# Nif for Elixir.Xler.Native
|
||||||
|
|
||||||
|
## To build the NIF module:
|
||||||
|
|
||||||
|
- Make sure your projects `mix.exs` has the `:rustler` compiler listed in the `project` function: `compilers: [:rustler] ++ Mix.compilers()` If there already is a `:compilers` list, you should append `:rustler` to it.
|
||||||
|
- Add your crate to the `rustler_crates` attribute in the `project function. [See here](https://hexdocs.pm/rustler/basics.html#crate-configuration).
|
||||||
|
- Your NIF will now build along with your project.
|
||||||
|
|
||||||
|
## To load the NIF:
|
||||||
|
|
||||||
|
```elixir
|
||||||
|
defmodule Xler.Native do
|
||||||
|
use Rustler, otp_app: <otp-app>, crate: "xler_native"
|
||||||
|
|
||||||
|
# When your NIF is loaded, it will override this function.
|
||||||
|
def add(_a, _b), do: :erlang.nif_error(:nif_not_loaded)
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
[This](https://github.com/hansihe/NifIo) is a complete example of a NIF written in Rust.
