Ironbar includes a simple IPC server which can be used to control it programmatically at runtime.
It also includes a command line interface, which can be used for interacting with the IPC server.
# CLI
This is shipped as part of the `ironbar` binary. To view commands, you can use `ironbar --help`.
You can also view help per-command, for example using `ironbar set --help`.
Responses are handled by writing their type to stdout, followed by any value starting on the next line.
Error responses are written to stderr in the same format.
Example:
```shell
$ ironbar set subject world
ok
$ ironbar get subject
ok
world
```
# IPC
The server listens on a Unix socket.
This can usually be found at `/run/user/$UID/ironbar-ipc.sock`.
Commands and responses are sent as JSON objects, denoted by their `type` key.
The message buffer is currently limited to `1024` bytes.
Particularly large messages will be truncated or cause an error.
## Commands
### `ping`
Sends a ping request to the IPC.
Responds with `ok`.
```json
{
"type": "ping"
}
```
### `inspect`
Opens the GTK inspector window.
Responds with `ok`.
```json
{
"type": "inspect"
}
```
### `get`
Gets an [ironvar](ironvars) value.
Responds with `ok_value` if the value exists, otherwise `error`.
```json
{
"type": "get",
"key": "foo"
}
```
### `set`
Sets an [ironvar](ironvars) value.
Responds with `ok`.
```json
{
"type": "set",
"key": "foo",
"value": "bar"
}
```
### `load_css`
### `get`
Loads an additional CSS stylesheet, with hot-reloading enabled.
Responds with `ok` if the stylesheet exists, otherwise `error`.
```json
{
"type": "load_css",
"path": "/path/to/style.css"
}
```
## Responses
### `ok`
The operation completed successfully, with no response data.
```json
{
"type": "ok"
}
```
### `ok_value`
The operation completed successfully, with response data.
```json
{
"type": "ok_value",
"value": "lorem ipsum"
}
```
### `error`
The operation failed.
Message is optional.
```json
{
"type": "error",
"message": "lorem ipsum"
}
```

In some configuration locations, Ironbar supports dynamic values,
meaning you can inject content into the bar from an external source.
Currently two dynamic content sources are supported - scripts and ironvars.
## Dynamic String
Dynamic strings can contain any mixture of static string elements, scripts and variables.
Scripts should be placed inside `{{double braces}}`. Both polling and watching scripts are supported.
Variables use the standard `#name` syntax. Variables cannot be placed inside scripts.
To use a literal hash, use `##`. This is only necessary outside of scripts.
Example:
```toml
label = "{{cat greeting.txt}}, #subject"
```
## Dynamic Boolean
Dynamic booleans can use a single source of either a script or variable to control a true/false value.
For scripts, you can just write these directly with no notation.
Only polling scripts are supported.
The script exit code is used, where `0` is `true` and any other code is `false.
For variables, use the standard `#name` notation.
An empty string, `0` and `false` are treated as false.
Any other value is true.
Example:
```toml
show_if = "exit 0" # script
show_if = "#show_module" # variable
```

Ironvars are runtime variables that can be referenced in several places in your config,
then set using the IPC server (such as via the CLI) using the `set` command.
Any UTF-8 string *without whitespace* is a valid key.
Any UTF-8 string is a valid value.
Reference values using `#my_variable`. These update as soon as the value changes.
You can set defaults using the `ironvar_defaults` key in your top-level config.
