10how we interact with computers, the separation of text-based programs and GUI
11ones. To be perfectly honest, I got pissed off one evening when I was cleaning
12up files on my computer. Normally, I go into console and do <code>ncdu</code> and check
13where the junk is. Then I start deleting stuff. Without any discrimination,
14usually. But when it comes to screenshots, I have learned that it's good to keep
15them somewhere near if I need to refer to something that I was doing. I am an
16avid screenshot taker. So at that point I checked Pictures folder and also did a
17basic search <code>find . -type f -name "*.jpg"</code> for all the JPEG files in my home
18directory and immediately got pissed off. Why can’t I see thumbnails in my
19terminal? I know why, but why in the year of 2022 this is still a problem. I am
20used to traversing my disk via terminal. I am faster, and I am more comfortable
21this way. But when it comes to visualization, I then need to revert to GUI
22applications and again find the same file to see it. I know that programs like
23<code>feh</code> and <code>sxiv</code> are available, but I would just like to see the preview. Like
24<a href=https://jupyter.org/>Jupyter notebook</a> or something similar. Just having it
25inline. Part of a result.<p>It also didn’t help that I was spending some time with the <a href=https://plan9.io/plan9/>Plan
269</a> Operating system. More specifically
27<a href=http://9front.org/>9FRONT</a>. The way that <a href=http://acme.cat-v.org/>ACME editor</a>
28handles text editing is just wonderful. Different and fresh somehow, even though
29it’s super old.<p>So, I went on a lookout for an interesting way of visualizing results of some
30query. I found these applications to be outstanding examples of how not to be a
31captive of a predetermined way of doing things.<ul><li><a href=https://www.wolfram.com/mathematica/>Wolfram Mathematica</a><li><a href=https://jupyter.org/>Jupyter notebooks</a><li><a href=http://www.9front.org>Plan 9 / 9FRONT</a><li><a href=https://templeos.org/>Temple OS</a><li><a href=https://www.gnu.org/software/emacs/>Emacs</a></ul><p>My idea is not as out there as ACME is, but it is a spin on the terminal
32emulators. I like the modes that Vi/Vim provides you with. I like the way the
33Emacs does its own <code>M-x</code> <code>M-c</code>. Furthermore, I really like how Mathematica and
34Jupyter present the data in a free flowing form. And I love how Temple OS is
35basically a C interpreter on some level.<blockquote><p><strong>Note:</strong> This is part 1 of the journey. Nowhere finished yet. I am just
36tinkering with this at the moment. This whole thing can easily spectacularly
37fail.</blockquote><p>So I started. I knew that I wanted to have the couple of modes, but I didn’t
38like the repetition of keystrokes, so the only option was to have some sort of
39toggle and indicate to the user that they are in a special mode. Like Vi does
40for Normal and Visual mode.<p>These modes would for the first version be:<ul><li><em>Preview mode</em> (toggle with Ctrl + P)<ul><li>When this mode would be enabled, the <code>ls</code> command would try to find images
41from the results and display thumbnails from them in the terminal itself.
42No ASCII art. Proper images. In a grid!</ul><li><em>Detach mode</em> (toggle with Ctrl + D)<ul><li>When this mode would be enabled, every command would open a new window
43and execute that command in it. This would be useful for starting <code>htop</code>
44in a separate window.</ul></ul><p>The reason for having these modes togglable is to not ask for previews every
45time. You enable a mode and until you disable it, it behaves that way. Purely
46out of ergonomic reasons.<p>I would like to treat every terminal I open as a session mentally. When I start
47using the terminal, I start digging deeper into the issue I am trying to
48resolve. And while I am doing this, I would like to open detached windows
49etc. A lot of these things can be done easily with something like
50<a href=https://i3wm.org/>i3</a>, but also that pull you out of the context of what you
51were doing. I would like to orchestrate everything from one single point.<p>In planning for this project, I knew that I would need to use a language like C
52and a library such as <a href=https://www.libsdl.org/>SDL2</a> in order to achieve the
53desired results. I had considered other options, but ultimately determined that
54<a href=https://www.libsdl.org/>SDL2</a> was the best fit based on its capabilities and
55reputation in the programming community.<p>At first, I thought the idea of a hardware accelerated terminal was a bit of a
56joke. It seemed like such a niche and unnecessary feature, especially given the
57fact that terminal emulators have been around for decades and have always relied
58on software rendering. But to be fair, <a href=https://alacritty.org/>Alacritty</a> is
59doing the same thing. Well, they are doing a remarkable job at it.<p>So, I embarked on a journey. Everything has to start somewhere. For me, it
60started with creating a window! It has to start somewhere. 🙂<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:green>// Oh, Hi Mark!
61</span></span></span><span style=display:flex><span><span style=color:green>// Create the window, obviously.
62</span></span></span><span style=display:flex><span><span style=color:green></span>SDL_Window *window = SDL_CreateWindow(
63</span></span><span style=display:flex><span> WINDOW_TITLE, SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED,
64</span></span><span style=display:flex><span> WINDOW_WIDTH, WINDOW_HEIGHT,
65</span></span><span style=display:flex><span> SDL_WINDOW_RESIZABLE | SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN);
66</span></span></code></pre><p>I continued like this to get some text displayed on the screen.<p>I noted that
67<a href=https://wiki.libsdl.org/SDL_ttf/TTF_RenderText_Solid><code>TTF_RenderText_Solid</code></a>
68rendered text really poorly. There were no antialiasing at all. In my wisdom, I
69never checked the documentation. Well, that was a fail. To uneducated like me:
70<code>TTF_RenderText_Solid</code> renders Latin1 text at fast quality to a new 8-bit
71surface. So, that's why the texts looked like shit. No wonder.<p>Remarks on <code>TTF_RenderText_Solid</code>: This function will allocate a new 8-bit,
72palettized surface. The surface's 0 pixel will be the colorkey, giving a
73transparent background. The 1 pixel will be set to the text color.<p>After I replaced it with
74<a href=https://wiki.libsdl.org/SDL_ttf/TTF_RenderText_LCD><code>TTF_RenderText_LCD</code></a> which
75renders Latin1 text at LCD subpixel quality to a new ARGB surface, the text
76started looking good. Really make sure you read the documentation. It’s actually
77good. As a side note, you can find all the documentation regarding <a href=https://wiki.libsdl.org/>SDL2 on
78their Wiki</a>.<p>After that was done, I started working on displaying other things like <code>Preview</code>
79and <code>Detach</code> modes. This wasn’t really that hard. In SDL2 you can check all the
80available events with <code>while (SDL_PollEvent(&amp;event) > 0)</code> and have a bunch of
81switch statements to determine which key is currently being pressed. More about
82keys, <a href=https://documentation.help/SDL/sdlkey.html>SDLKey</a> and mroe about
83pooling the events on
84<a href=https://documentation.help/SDL/sdlpollevent.html>SDL_PollEvent</a>.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>while</span> (SDL_PollEvent(&amp;event) &gt; 0)
85</span></span><span style=display:flex><span>{
86</span></span><span style=display:flex><span> <span style=color:#00f>switch</span> (event.type)
87</span></span><span style=display:flex><span> {
88</span></span><span style=display:flex><span> <span style=color:#00f>case</span> SDL_QUIT:
89</span></span><span style=display:flex><span> running = false;
90</span></span><span style=display:flex><span> <span style=color:#00f>break</span>;
91</span></span><span style=display:flex><span>
92</span></span><span style=display:flex><span> <span style=color:#00f>case</span> SDL_TEXTINPUT:
93</span></span><span style=display:flex><span> <span style=color:#00f>if</span> (!meta_key_pressed)
94</span></span><span style=display:flex><span> {
95</span></span><span style=display:flex><span> strncat(input_prompt_text, event.text.text, 1);
96</span></span><span style=display:flex><span> update_input_prompt = true;
97</span></span><span style=display:flex><span> }
98</span></span><span style=display:flex><span> <span style=color:#00f>break</span>;
99</span></span><span style=display:flex><span> }
100</span></span><span style=display:flex><span>}
101</span></span></code></pre><p>After that was somewhat working correctly, I started creating a struct that
102would hold all the commands and results and I call them Cells. Yes, I stole that
103naming idea from Jupyter.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>typedef</span> <span style=color:#00f>struct</span>
104</span></span><span style=display:flex><span>{

106</span></span><span style=display:flex><span> <span style=color:#2b91af>char</span> *result;
107</span></span><span style=display:flex><span> SDL_Surface *surface;
108</span></span><span style=display:flex><span> SDL_Texture *texture;
109</span></span><span style=display:flex><span> SDL_Rect rect;
110</span></span><span style=display:flex><span>} Cell;
111</span></span></code></pre><p>I am at a place now where I am starting to implement scrolling. This will for
112sure be fun to code. Memory management in C is super easy. 😂<p>I have also added a simple <a href=https://en.wikipedia.org/wiki/INI_file>INI file like
113configuration</a> support. It is done in an
114<a href=https://github.com/nothings/stb/blob/master/docs/stb_howto.txt>STB style of
115header</a> and maps
116to specific options supported by the terminal. It is not universal, and the code
117below demonstrates how I will use it in the future.<pre tabindex=0 style=background-color:#fff><code><span style=display:flex><span><span style=color:#00f>#ifndef CONFIG_H
