|
||
|
<p>You can think of xplr as a server. Just like web servers listen to HTTP
|
||
|
requests, xplr listens to messages.</p>
|
||
|
<p>See the
|
||
|
<a href="https://docs.rs/xplr/latest/xplr/app/enum.ExternalMsg.html#variants"><strong>full list of messages</strong></a>
|
||
|
that xplr can handle.</p>
|
||
|
<p>You can send messages to an xplr session in the following ways:</p>
|
||
|
<ul>
|
||
|
<li>Via <a href="modes.html#key-bindings">key bindings</a></li>
|
||
|
<li>Via <a href="#lua-function-calls">Lua function calls</a></li>
|
||
|
<li>Via shell using the <a href="#input-pipe">input pipe</a></li>
|
||
|
</ul>
|
||
|
<h2 id="format"><a class="header" href="#format">Format</a></h2>
|
||
|
<p>To send messages using <a href="modes.html#key-bindings">key bindings</a> or
|
||
|
<a href="#lua-functions-calls">Lua functions calls</a>, these are represented in
|
||
|
<a href="https://www.lua.org/">Lua</a> syntax. For example:</p>
|
||
|
<ul>
|
||
|
<li>"Quit"</li>
|
||
|
<li>{ FocusPath = "/path/to/file" }</li>
|
||
|
<li>{ Call = { command = "bash", args = { "-c", "read -p test" } } }</li>
|
||
|
</ul>
|
||
|
<p>However, to send messages using the <a href="#input-pipe">input pipe</a>, they need to be
|
||
|
represented using
|
||
|
<a href="http://yaml.org/">YAML</a> (or <a href="https://www.json.org">JSON</a>) syntax. For example:</p>
|
||
|
<ul>
|
||
|
<li>Foo</li>
|
||
|
<li>FocusPath: "/path/to/file"</li>
|
||
|
<li>Call: { command: bash, args: ["-c", "read -p test"] }</li>
|
||
|
</ul>
|
||
|
<h2 id="lua-function-calls"><a class="header" href="#lua-function-calls">Lua Function Calls</a></h2>
|
||
|
<p>xplr allows users to define lua functions using the <code>xplr.fn.custom</code> Lua API.</p>
|
||
|
<p>These functions can be called using messages like <code>CallLua</code>, <code>CallLuaSilently</code>.</p>
|
||
|
<p>When called the function receives a <a href="#calllua-argument">special argument</a> that
|
||
|
contains some useful information. The function can optionally return a list of
|
||
|
messages which will be handled by xplr.</p>
|
||
|
<p>Example:</p>
|
||
|
<pre><code class="language-lua">-- Define the function
|
||
|
xplr.fn.custom.ask_name_and_greet = function(app)
|
||
|
print("What's your name?")
|
||
|
|
||
|
local name = io.read()
|
||
|
local greeting = "Hello " .. name .. "!"
|
||
|
local message = greeting .. " You are inside " .. app.pwd
|
||
|
|
||
|
return {
|
||
|
{ LogSuccess = message },
|
||
|
}
|
||
|
end
|
||
|
|
||
|
-- Map the function to a key (space)
|
||
|
xplr.config.modes.builtin.default.key_bindings.on_key.space = {
|
||
|
help = "and & greet",
|
||
|
messages = {
|
||
|
{ CallLua = "custom.ask_name_and_greet" }
|
||
|
}
|
||
|
}
|
||
|
|
||
|
-- Now, when you press "space" in default mode, you will be prompted for your
|
||
|
-- name. Enter your name to receive a nice greeting and to know your location.
|
||
|
</code></pre>
|
||
|
<h3 id="calllua-argument"><a class="header" href="#calllua-argument">CallLua Argument</a></h3>
|
||
|
<p>This is a special argument passed to the lua functions when called using the
|
||
|
<code>CallLua</code>, <code>CallLuaSilently</code> messages.</p>
|
||
|
<p>It contains the following information:</p>
|
||
|
<ul>
|
||
|
<li>version</li>
|
||
|
<li>config</li>
|
||
|
<li>pwd</li>
|
||
|
<li>focused_node</li>

|
||
|
<p>Alternative to <code>CallLua</code>, <code>CallLuaSilently</code> messages that call Lua functions,
|
||
|
there are <code>Call</code>, <code>CallLuaSilently</code>, <code>BashExec</code>, <code>BashExecSilently</code> messages
|
||
|
that call shell commands.</p>
|
||
|
<p>However, unlike the Lua functions, these shell commands have to read the useful
|
||
|
information and send messages via environment variables and temporary files
|
||
|
called "pipe"s. These environment variables and files are only available when
|
||
|
a command is being executed.</p>

<p>Visit the <a href="modes.html#tutorial-adding-a-new-mode"><strong>fzf integration tutorial</strong></a>
