What do you like about them? I disagree, but so many people seem to like them that I assume I'm missing something. The main one I've heard before is that they work nicely over SSH, but I assume there must be more?
- They encourage developing simpler, information-dense, and keyboard-driven interfaces, which I tend to prefer in general.
- I find them more fun to write, and less aggravating to maintain and debug, than interfaces built with GUI toolkits.
- Most software I write for personal use is going to be run in both a Linux and Mac OS environment (and a lot of the time on a headless server to boot), and a TUI often has less fuss than other options (at least, IME).
- I think monospaced text in a terminal just looks cool.
Anything that lends itself to keyboard input, piping, text manipulation and a bunch of other things are so much faster if you're equally proficient in both input modes.
YMMV, of course, I'm just sharing my own experience and perspective.
It is, of course, completely subjective, but I know there are a fair number of people out there who agree with that statement.
If there was a powerful, information dense, configurable docking/tiling, multi-application-composing GUI framework (all things a good terminal can do) then yes, build everything in that. I’d love to see it.
Until then, TUIs are vastly better than another Electron app or Mac app using UI frameworks that are trying their hardest to look and act like basic phone apps.
So even professional tools all follow industry design and product trends which are too simplistic, don’t give you the info you need, and are optimized for abstract brand design or chasing metrics for the company, and not optimized for “how do I let my user accomplish their task as fast as possible”
- keyboard can be used for pretty much everything
- less visually busy (no/less animations, background images/color variations. often close to plain text on plain background)
- more information dense (fewer things hidden behind hamburger menus, modals, drawers, etc)
- more/more easily customizable and documented
- more often can provide data directly into the terminal that I'm working in, so don't need to copy/paste through windows etc
these aren't necessarily impossible for GUI or universally true for TUI, but maybe I would guess just more an artifact of there being types of people who prefer working in the terminal who are then more likely to make TUIs, and I share their preferences more.
I love how I have to configure font size and family only once in the terminal emulator and not for each program/GUI toolkit again.
Of course, there is no way to replace graphical-heavy programs (GIMP, QGIS etc.) with TUIs.
- Some are very good tools that have no clear GUI superiors. Vim, Emacs, Mc for example. GUI wrappers over these don't make them better.
- Efficient, meaning fast and limited in scope so you can learn the whole thing.
- The muscle memory you develop is transferable to any new platform or OS you use.
- Often free and OSS so they can't be taken away, making the muscle memory a long-term investment.
- If you work in the terminal for any other reason there's less context switch.
The low bandwidth / high latency lossy link problem is still a major issue. Cell phone service is sufficiently shitty in the area I live in that I have to use mosh to get a usable remote connection many times a year. Mosh is also quite useful while travelling! Got a crappy connection on a train or airplane? No problem. I have so much muscle memory with the mutt email client that nothing else has ever come close. Where's the equivalent of mutt's limit command in Thunderbird?
Try getting a usable VNC session when your cell phone hot spot is hitting 2-30 second ping times (yes -- thirty seconds) with only a handful of packets getting through.
Version 2 of the Amiga's operating system did a great thing in version 2 of AmigaOS which explicitly spelled out what conventions to apply (see Amiga User Interface Style Guide at https://archive.org/details/amiga-user-interface-style-guide). Modern GUIs that have weird meaningless buttons are infuriating. Even moreso when they lack obvious keyboard shortcuts.
I enjoy the usability and self perceived speed of not having to leave the console or reach the mouse to move a pointer when a cople of key presees is enough.
It's a matter of choice, I know, but I also think there is a genuine case for text over graphics. I see it everyday on businesses that keep old cobol tpvs at the cash, the speed at which the clercks check inventories or perform other crm activities is unmatched to mouse or touch interfaces
If you want to automate from the perspective of what's on screen, tuis have no metadata. A button in a gui does have metadata associated with it, so you could automate 'click button x' where as in a TUI you'd be limited to clicking 'position x,y'
For GUIs you have to handle the particular metadata of a given framework, if it exposes metadata at all for the controls. Otherwise you're dealing with raw pixels which is an instant nightmare, though not so much now there are visual LLMs, but you're still paying for the tokens and/or extra processing.
