<!-- ABOUT THE PROJECT -->

## About The Project

![Product Name Screen Shot][product-screenshot1]
![Product Name Screen Shot][product-screenshot2]

This project is heavily inspired by [Lazygit](https://github.com/jesseduffield/lazygit), which I think is the best TUI client for Git.

I wanted to have a tool like that, but for SQL. I didn't find one that fits my needs, so I created one myself.

I live in the terminal, so if you are like me, this tool can become handy for you too.

This is my first Open Source project, also, this is my first Go project. I am not a brilliant programmer. I am just a typical JavaScript developer that wanted to learn a new language, I also wanted a TUI SQL Client, so blanca y en botella, leche! (white and bottled).

This project is in ALPHA stage, please feel free to complain about my spaghetti code.

I use Lazysql daily in my full-time job as a full-stack javascript developer in its current (buggy xD) state. So, the plan is to improve and fix my little boy as a side-project in my free time.

<!-- USAGE EXAMPLES -->

## Configuration

If the `XDG_CONFIG_HOME` environment variable is set, the configuration file will be located at:

- `${XDG_CONFIG_HOME}/lazysql/config.toml`

If not, the configuration file will be located at:

- Windows: `%APPDATA%\lazysql\config.toml`
- macOS: `~/Library/Application Support/lazysql/config.toml`
- Linux: `~/.config/lazysql/config.toml`

The configuration file is a TOML file and can be used to define multiple connections.

### Example configuration

```toml
[[database]]
Name = 'Production database'
Provider = 'postgres'
DBName = 'foo'
URL = 'postgres://postgres:urlencodedpassword@localhost:${port}/foo'
Commands = [
  { Command = 'ssh -tt remote-bastion -L ${port}:localhost:5432', WaitForPort = '${port}' }
]
[[database]]
Name = 'Development database'
Provider = 'postgres'
DBName = 'foo'
URL = 'postgres://postgres:urlencodedpassword@localhost:5432/foo'
[application]
DefaultPageSize = 300
DisableSidebar = false
SidebarOverlay = false
```

The `[aplication]` section is used to define some app settings. Not all settings are available yet, this is a work in progress.

## Usage

> For a list of keyboard shortcuts press `?`

Open the TUI with:
```console
$ lazysql
```

To launch lazysql with the ability to pick from the saved connections.
```console
$ lazysql [connection_url]
```

To launch lazysql and connect to database at [connection_url].

### Connect to a DB

1. Start `lazysql`
2. Create a new connection (press `n`)
3. Provide a name for the connection as well as the URL to connect to (see <a href="#example-connection-urls">example connection URL</a>)
4. Connect to the DB (press `<Enter>`)

If you already have a connection set up:
1. Start `lazysql`
2. Select the right connection (press `j` and `h` for navigation)
3. Connect to the DB (press `c` or `<Enter>`)

### Create a table

There is currently no way to create a table from the TUI.
However you can run the query to create the table as a SQL-Query, 
inside the <a href="#execute-sql-querys">SQL Editor</a>.

You can update the tree by pressing `R`, so you can see your newly created table.

### Execute SQL querys

1. Press `<Ctrl+E>` to open the built-in SQL Editor
2. Write the SQL query
3. Press `<Ctrl+R>` to execute the SQL query

> To switch back to the table-tree press `H`
>
> After executing a `SELECT`-query a table will be displayed under the SQL-Editor
> with the query-result. \
> To switch focus back to SQL-Editor press `/`

### Open/view a table

1. Expand the table-tree by pressing `e` or `<Enter>`
2. Select the table you want to view
    - next node `j`
    - previous node `k`
    - last node `G`
    - first node `g`
3. Press `<Enter>` to open the table

> To switch back to the table-tree press `H` \
> To switch back to the table press `L`

### Filter rows

1. [Open a table](#openview-a-table)
2. Press `/` to focus the filter input
3. Write a `WHERE`-clause to filter the table
4. Press `<Enter>` to submit your filter

> To remove the filter, focuse the filter input (press `/`) and press `<Esc>`.

### Insert a row

1. [Open a table](#openview-a-table)
2. Press `1` to switch to the record tab
3. Press `o` to insert a new row
4. Fill out all columns
5. Press `<Ctrl+S>` to save the changes

### Edit a column

1. [Open a table](#openview-a-table)
2. Press `1` to switch to the record tab
3. Move to the column you want to edit
4. Press `c` to edit, Press `<Enter>` to submit
5. Press `<Ctrl+S>` to save the changes

## Support

- [x] MySQL
- [x] PostgreSQL
- [x] SQLite
- [x] MSSQL
- [ ] MongoDB

Support for multiple RDBMS is a work in progress.

<!-- COMMANDS -->

## Commands

In some cases, mostly when connecting to remote databases, it might be necessary to run a custom command
before being able to connect to the database. For example when you can only access the database through
a remote bastion, you would probably first need to open an SSH tunnel by running the following command
in a separate terminal:

```bash
ssh remote-bastion -L 5432:localhost:5432
```

In order to make it easier to run these commands, lazysql supports running custom commands before connecting
to the database. You can define these commands in the configuration file like this:

```toml
[[database]]
Name = 'server'
Provider = 'postgres'
DBName = 'foo'
URL = 'postgres://postgres:password@localhost:${port}/foo'
Commands = [
  { Command = 'ssh -tt remote-bastion -L ${port}:localhost:5432', WaitForPort = '${port}' }
]
```

The `Command` field is required and can contain any command that you would normally run in your terminal.
The `WaitForPort` field is optional and can be used to wait for a specific port to be open before continuing.

When you define the `${port}` variable in the URL field, lazysql will automatically replace it with a random
free port number. This port number will then be used in the connection URL and is available in the `Commands`
field so that you can use it to configure the command.

You can even chain commands to, for example, connect to a remote server and then to a postgres container
running in a remote k8s cluster:

```toml
[[database]]
Name = 'container'
Provider = 'postgres'
DBName = 'foo'
URL = 'postgres://postgres:password@localhost:${port}/foo'
Commands = [
  { Command = 'ssh -tt remote-bastion -L 6443:localhost:6443', WaitForPort = '6443' },
  { Command = 'kubectl port-forward service/postgres ${port}:5432 --kubeconfig /path/to/kube.conf', WaitForPort = '${port}' }
]
```
