1. Tab titles are set using escape sequences, typically OSC 0, 1 or 2. You can find examples for configuring shells to emit those online, for example: https://superuser.com/questions/84710/window-title-in-bash Terminal.app defaults to snooping the local process list to set titles; wezterm doesn't do this as the terminal may not be local (eg: could be remote ssh or multiplexer session) and using escape sequences gives definitive control.
2. I'd love to troubleshoot this with you; please file an issue!
3. There are currently a set of open and related IME/macOS issues at the moment. You may want to try looking at https://wezfurlong.org/wezterm/config/keys.html#macos-left-a... and fiddle with those options, but you may be left disappointed until the root of those issues are resolved!
4. This is a consequence of being a cross platform program rather than a macOS-first application. There isn't a way to keep the GUI running without any Windows today. Perhaps in the future?
My configuration for Wezterm at the moment:
- I set the color scheme to Afterglow, which is a lot like the default color scheme of Terminal.app.
- I downloaded the SF Mono font from https://developer.apple.com/fonts/ so that it is available to Wezterm, and I defined the font size to be the one that I prefer. This is the font that Terminal.app uses by default but I guess in Terminal.app this font is actually bundled inside of the application because the font did not show up in Font Book and Wezterm couldn't find it either until I downloaded it from said link and installed it even though Terminal.app is already using it.
- I configured Command + K to clear not just scrollback (Wezterm default), but to also clear the viewport like Terminal.app does.
- I turned off tabs.
The are only a few things at the moment that I dislike about Wezterm:
1. The title of each window is simply "Wezterm", and tabs provide additional info but since I am not using tabs and the windows still are titled just "Wezterm" I am missing having the title of the Window be set to things like the current working directory and the currently running commands the way that Terminal.app does.
2. https://wezfurlong.org/wezterm/faq.html says that WezTerm version 20200620-160318-e00b076c and newer will automatically set $LANG appropriately on macOS, but I am using version 20211205-192649-672c1cc1 installed from homebrew on macOS Monterey 12.0.1, and it is not setting $LANG for me.
3. I am unable to input characters like æ, ø, å the way that I usually do which is Option + ', Option + o, and Option + a respectively on macOS with the macOS input language set to US. I don't know if this is a consequence of $LANG not being set that I mentioned above or if it's due to the application perhaps not using the operating system provided input methods.
4. When I close the last window the application closes, which is counter to how most applications on macOS work by default, and counter to how Terminal.app works by default. I often close terminals including the last terminal and then later like to tab back to Terminal.app and open a new window. With Wezterm I have to relaunch the application before I can open a new window after I have closed the last window.
Is there a way to make the Wezterm application stay running on macOS when I close the last window?
