agda-pkg [![PyPI version](https://badge.fury.io/py/agda-pkg.svg)](https://badge.fury.io/py/agda-pkg) [![Build Status](https://travis-ci.org/agda/agda-pkg.svg?branch=master)](https://travis-ci.org/agda/agda-pkg)
========

Agda-Pkg is a tool to manage Agda libraries with extra features like
installing libraries from different kind of sources. This tool does
not modify `Agda` at all, it just manages systematically the directory
`.agda` and the files: `.agda/defaults` and `.agda/libraries` used by
Agda to locate libraries. For more information about how Agda package
system works, please read the official documentation
[here](https://agda.readthedocs.io/en/v2.6.0/tools/package-system.html).


We have indexed in
[agda/package-index](http://github.com/agda/package-index) some agda
libraries available on Github. We can install them with `agda-pkg install LibraryName`.

<!-- /TOC -->

# Quick Start

To install `agda-pkg`, you must have installed `Python 3.6+` or a latter version
on your machine. In addition, the python package manager `pip 18.0+`.

We have tested `agda-pkg` with `Agda v2.5.4+`.

Installing using `pip`:

```
    $ pip install agda-pkg
```

Now, we can run the package manager using the command `agda-pkg` or even
shorter just `apkg`.

# Usage

## Initialisation of the package index

The easiest way to get some libraries is by using [the package index].
We will use this index to download and to install the libraries. In
addition, `agda-pkg` uses a local database to maintain a register of
all libraries available in your system. To initialise the index and
the database please run the following command:

```
    $ apkg init
    Indexing libraries from https://github.com/agda/package-index.git
```

**Note**.
To use a different location for the files `defaults` and `libraries` for Agda,
you can set up the environment variable `AGDA_DIR` as fallows.

```
    $ export AGDA_DIR=$HOME/.agda
```

Other way is to create a directory `.agda` in your directory and run
`agda-pkg` from that directory. `agda-pkg` will prioritize the `.agda`
directory in the current directory.

## Help command

Check all the options of a command or subcommand by using the flag `--help`.

```
    $ apkg --help
    $ apkg install --help
```

## Upgrade the package index

Recall updating the index every once in a while using `upgrade`.

```
    $ apkg upgrade
    Updating Agda-Pkg from https://github.com/agda/package-index.git
```

If you want to index your library go to [the package index] and make [PR].

## List all the packages available

To see all the packages available run the following command:

```
    $ apkg list
```

This command also has the flag `--full` to display a version of the
this list with more details.


## Installation of packages

Install a library is now easy. We have multiple ways to install a package.

<img src="https://github.com/agda/agda-pkg/raw/master/assets/index-stdlib.gif"
 alt="agda package manager installation" width=350 align="right" />

 -   from the [package-index](http://github.com/agda/package-index)

 ```
     $ apkg install standard-library
 ```

-   from a [local directory]

```
    $ apkg install .
```

or even much simpler:

```
    $ apkg install
```

Installing a library creates a copy for agda in the directory assigned
by agda-pkg. If you want your current directory to be taken into
account for any changes use the `--editable` option.  as shown below.


```
    $ apkg install --editable .
```

-   from a github repository

```
    $ apkg install --github agda/agda-stdlib --version v0.16
```

-   from a git repository

```
    $ apkg install http://github.com/jonaprieto/agda-prop.git
```

To specify the version of a library, we use the flag `--version`

```
    $ apkg install standard-library --version v1.0
```

Or simpler by using `@` or `==` as it follows.

```
    $ apkg install standard-library@v1.0
    $ apkg install standard-library==v1.0
```

### Multiple packages at once

To install multiple libraries at once, we have two options:

1. Using the inline method

```
    $ apkg install standard-library agda-prop agda-metis
```

Use `@` or `==` if you need a specific version, see above
examples.

2. Using a requirement file:

Generate a requirement file using `apkg freeze`:

```
    $ apkg freeze > requirements.txt
    $ cat requirements.txt
    standard-library==v0.16
````

Now, use the flag `-r` to install all the listed libraries
in this file:

```
    $ apkg install -r requirements.txt
```


Check all the options of this command with the help information:

```
    $ apkg install --help
```

## Uninstalling a package

Uninstalling a package will remove the library from the visible libraries for Agda.

- using the name of the library

```
    $ apkg uninstall standard-library
```

- infering the library name from the current directory

```
    $ apkg uninstall .
```

And if we want to remove the library completely (the sources and
everything), we use the flag `--remove-cache`.

```
    $ apkg uninstall standard-library --remove-cache
```

## Update a package to latest version

We can get the latest version of a package from
the versions registered in the package-index.

- Update all the installed libraries:

```
    $ apkg update
```

- Update a specific list of libraries. If some
library is not installed, this command will installed
the latest version of it.

```
    $ apkg update standard-library agdarsec
```

## See packages installed


```
    $ apkg freeze
    standard-library==v0.16
```

This command is useful to keep in a file the versions used for your project
to install them later.


```
    $ apkg freeze > requirements.txt
```

To install from this requirement file run this command.


```
    $ apkg install < requirements.txt
```

## Approximate search of packages

We make a search (approximate) by using keywords and title of the
packages from the index. To perform such a search, see the following
example:


```
    $ apkg search metis
    1 result in 0.0012656739999998834seg
    cubical
    url: https://github.com/agda/cubical.git
    installed: False
```

## Get all the information of a package


```
    $ apkg info cubical

```

# Creating a library for Agda-Pkg

In this section, we describe how to build a library.

To build a project using `agda-pkg`, we just run the following command:

```
    $ apkg create
```

Some questions are going to be prompted in order to create
the necessary files for Agda and for Agda-Pkg.

The output is a folder like the following showed below.

## Directory structure of an agda library

A common Agda library has the following structure:

```
$ tree -L 1 mylibrary/
mylibrary/
├── LICENSE
├── README.md
├── mylibrary.agda-lib
├── mylibrary.agda-pkg
├── src
└── test

2 directories, 3 files
```

## .agda-lib library file

```yaml
$ cat mylibrary.agda-lib
name: mylibrary  -- Comment
depend: LIB1 LIB2
  LIB3
  LIB4
include: PATH1
  PATH2
  PATH3
```

## .agda-pkg library file

This file only works for `agda-pkg`. The idea of
this file is to provide more information about the
package, pretty similar to the cabal files in Haskell.
This file has priority over its version `.agda-lib`.

```yaml
$ cat mylibrary.agda-pkg
name:              mylibrary
version:           v0.0.1
author:
