Technically, it is possible to include any HTTPie options in there.
|
||||
However, it is not recommended to modify the default behavior in a way that would break your compatibility with the wider world as that may become confusing.
|
||||
|
||||
#### `plugins_dir`
|
||||
|
||||
The directory where the plugins will be installed. HTTPie needs to have read/write access on that directory, since
|
||||
`httpie plugins install` will download new plugins to there.
|
||||
|
||||
### Un-setting previously specified options
|
||||
|
||||
Default options from the config file, or specified any other way, can be unset for a particular invocation via `--no-OPTION` arguments passed via the command line (e.g., `--no-style` or `--no-session`).

Also, it might be good to set a connection `--timeout` limit to prevent your program from hanging if the server never responds.
|
||||
|
||||
## Plugins Manager
|
||||
|
||||
HTTPie offers extensibility through plugins, and there are over 50+ of them available to try!
|
||||
They add things like new authentication methods ([akamai/httpie-edgegrid](https://github.com/akamai/httpie-edgegrid)),
|
||||
transport mechanisms ([httpie/httpie-unixsocket](https://github.com/httpie/httpie-unixsocket)),
|
||||
message convertors ([banteg/httpie-image](https://github.com/banteg/httpie-image)), or simply
|
||||
change how a response is formatted.
|
||||
|
||||
> Note: Plugins are usually made by our community members, and thus have no direct relationship with
|
||||
> the HTTPie project. We do not control / review them at the moment, so use them at your own discretion.
|
||||
|
||||
For managing these plugins; starting with 3.0, we are offering a new plugin manager.
|
||||
|
||||
This command is currently in beta.
|
||||
|
||||
### `httpie plugins`
|
||||
|
||||
`plugins` interface is a very simple plugin manager for installing, listing and uninstalling HTTPie plugins.
|
||||
|
||||
> In the past `pip` was used to install/uninstall plugins, but on some environments (e.g brew installed
|
||||
packages) it wasn't working properly. The new interface is a very simple overlay on top of `pip` to allow
|
||||
plugin installations on every installation method.
|
||||
|
||||
> By default the plugins (and their missing dependencies) will be stored under the configuration directory,
|
||||
but this can be modified through `plugins_dir` variable on the config.
|
||||
|
||||
#### `httpie plugins install`
|
||||
|
||||
For installing plugins from [PyPI](https://pypi.org/) or from local paths, `httpie plugins install`
|
||||
can be used.
|
||||
|
||||
```bash
|
||||
$ httpie plugins install httpie-plugin
|
||||
Installing httpie-plugin...
|
||||
Successfully installed httpie-plugin-1.0.2
|
||||
```
|
||||
|
||||
> Tip: Generally HTTPie plugins start with `httpie-` prefix. Try searching for it on [PyPI](https://pypi.org/search/?q=httpie-)
|
||||
> to find out all plugins from the community.
|
||||
|
||||
#### `httpie plugins list`
|
||||
|
||||
List all installed plugins.
|
||||
|
||||
```bash
|
||||
$ httpie plugins list
|
||||
httpie_plugin (1.0.2)
|
||||
httpie_plugin (httpie.plugins.auth.v1)
|
||||
httpie_plugin_2 (1.0.6)
|
||||
httpie_plugin_2 (httpie.plugins.auth.v1)
|
||||
httpie_converter (1.0.0)
|
||||
httpie_iterm_converter (httpie.plugins.converter.v1)
|
||||
httpie_konsole_konverter (httpie.plugins.converter.v1)
|
||||
```
|
||||
|
||||
#### `httpie plugins uninstall`
|
||||
|
||||
Uninstall plugins from the isolated plugins directory. If the plugin is not installed
|
||||
through `httpie plugins install`, it won't uninstall it.
|
||||
|
||||
```bash
|
||||
$ httpie plugins uninstall httpie-plugin
|
||||
```
