## Overview

You can quickly switch between Posting and external editors and pagers.

For example, you could edit request bodies in `vim`, and then browse the JSON response body in `less` or `fx`.

You can even configure a custom pager specifically for browsing JSON.

## External Editors

With a multi-line text area focused, press ++f4++ to open the file in your
configured external editor.

The configured external editor can be set as `editor` in your `config.yaml`
file.
For example:

```yaml title="config.yaml"
editor: vim
```

Alternatively, you can set the `POSTING_EDITOR` environment variable.

```bash
export POSTING_EDITOR=vim
```

If neither is set, Posting will try to use the `EDITOR` environment variable.

## External Pagers

With a multi-line text area focused, press ++f3++ to open the file in your
configured external pager.

The configured external pager can be set as `pager` in your `config.yaml`
file.
For example:

```yaml title="config.yaml"
pager: less
```

Alternatively, you can set the `POSTING_PAGER` environment variable.

```bash
export POSTING_PAGER=less
```

### JSON Pager

You can use a custom pager for viewing JSON using the `pager_json` setting in
your `config.yaml` file.
For example:

```yaml title="config.yaml"
pager_json: fx
```

Alternatively, you can set the `POSTING_PAGER_JSON` environment variable.

```bash
export POSTING_PAGER_JSON=fx
```

If neither is set, Posting will try to use the default pager lookup rules discussed earlier.

## Exporting to curl

> *Added in Posting 2.4.0*

Open the command palette and select `export: copy as curl`.
This will transform the open request into a cURL command, and copy it to your clipboard.

You can optionally supply extra arguments to pass to curl by setting the `curl_export_extra_args` setting in your `config.yaml` file.

```yaml title="config.yaml"
curl_export_extra_args: "--verbose -w %{time_total} %{http_code}"
```

This will be inserted directly into the command that gets copied to your clipboard, immediately after `curl `,
producing a command like the following:

```bash
curl --verbose -w %{time_total} %{http_code} -X POST ...
```
