<title>OSC-52</title>
16
+
<description><p>I use <code>ssh</code> a lot. Copying text from the remote machine to
17
+
the host machine always sucked. But OSC-52 makes that easy.</p>
18
+
<p>OSC-52 is an ANSI escape sequence to write text to the terminal
19
+
emulator. The terminal emulator, if it understands what is going on,
20
+
will in turn write this text to the system clipboard.</p>
21
+
<p>What this means is some <code>printf</code> magic can send text to
22
+
your clipboard. I store this one-liner in a script called
23
+
<code>oclip</code>:</p>
24
+
<div class="sourceCode" id="cb1"><pre
25
+
class="sourceCode bash"><code class="sourceCode bash"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="bu">printf</span> <span class="st">&quot;\033]52;c;%s\007&quot;</span> <span class="st">&quot;</span><span class="va">$(</span><span class="fu">base64</span> <span class="op">&lt;&amp;</span><span class="dv">0</span><span class="va">)</span><span class="st">&quot;</span></span></code></pre></div>
26
+
<p>and I run it with:</p>
27
+
<div class="sourceCode" id="cb2"><pre
28
+
class="sourceCode bash"><code class="sourceCode bash"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a><span class="ex">remote</span> $ cat some_file.txt <span class="kw">|</span> <span class="ex">oclip</span></span>
29
+
<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a></span>
30
+
<span id="cb2-3"><a href="#cb2-3" aria-hidden="true" tabindex="-1"></a><span class="co"># some_file.txt&#39;s contents are now the host&#39;s clipboard</span></span></code></pre></div>
31
+
<h3 id="the-catch">The catch</h3>
32
+
<p>Your terminal emulator must support OSC-52, <code>alacritty</code>
33
+
and <code>termux</code> seem to support this out of the box. In
34
+
<code>st</code>, OSC-52 works with this change to
35
+
<code>config.h</code>:</p>
36
+
<pre><code>int allowwindowops = 1;</code></pre>
37
+
<p>If you are using <code>tmux</code>, you need to flip this switch
38
+
on:</p>
39
+
<pre><code>set -s set-clipboard on</code></pre>
40
+
<p>If you are inside <code>nvim</code>, it may work as expected as long
41
+
as <code>$SSH_TTY</code> is set. I sometimes physically start a session,
42
+
and <code>ssh</code> into the same session later from another machine,
43
+
and <code>$SSH_TTY</code> remains unset, so I force OSC-52 in
44
+
<code>nvim</code> at all times (see <a
45
+
href="https://neovim.io/doc/user/provider.html#clipboard-osc52">nvimdoc</a>):</p>

I use `ssh` a lot. Copying text from the remote machine to
2
+
the host machine always sucked. But OSC-52 makes that easy.
3
+
4
+
OSC-52 is an ANSI escape sequence to write text to the
5
+
terminal emulator. The terminal emulator, if it understands
6
+
what is going on, will in turn write this text to the system
7
+
clipboard.
8
+
9
+
What this means is some `printf` magic can send text to your
10
+
clipboard. I store this one-liner in a script called
11
+
`oclip`:
12
+
13
+
```bash
14
+
printf "\033]52;c;%s\007" "$(base64 <&0)"
15
+
```
16
+
17
+
and I run it with:
18
+
19
+
```bash
20
+
remote $ cat some_file.txt | oclip
21
+
22
+
# some_file.txt's contents are now the host's clipboard
23
+
```
24
+
25
+
### The catch
26
+
27
+
Your terminal emulator must support OSC-52, `alacritty` and
28
+
`termux` seem to support this out of the box. In `st`,
29
+
OSC-52 works with this change to `config.h`:
30
+
31
+
```
32
+
int allowwindowops = 1;
33
+
```
34
+
35
+
If you are using `tmux`, you need to flip this switch on:
36
+
37
+
```
38
+
set -s set-clipboard on
39
+
```
40
+
41
+
If you are inside `nvim`, it may work as expected as long as
42
+
`$SSH_TTY` is set. I sometimes physically start a session,
43
+
and `ssh` into the same session later from another machine,
44
+
and `$SSH_TTY` remains unset, so I force OSC-52 in `nvim` at
45
+
all times (see
46
+
[nvimdoc](https://neovim.io/doc/user/provider.html#clipboard-osc52)):
47
+
48
+
```lua
49
+
vim.g.clipboard = {
50
+
name = 'OSC 52',
51
+
copy = {
52
+
['+'] = require('vim.ui.clipboard.osc52').copy('+'),
53
+
['*'] = require('vim.ui.clipboard.osc52').copy('*'),
54
+
},
55
+
paste = {
56
+
['+'] = require('vim.ui.clipboard.osc52').paste('+'),
57
+
['*'] = require('vim.ui.clipboard.osc52').paste('*'),
58
+
},
59
+
}
60
+
```
61
+
62
+
If you are inside `nvim` inside `tmux` inside an `ssh`
63
+
session inside `st`, you neeed all of the above tweaks.
64
+
`nvim` will pass the contents around to `tmux`, which in
65
+
turn will pass the contents to `st`, which should pass it to
66
+
your system clipboard.
