Looking at tcsetattr(3) § Canonical and noncanonical mode:
In canonical mode:
[…]
The maximum line length is 4096 chars (including the terminating newline character); lines longer than 4096 chars are truncated.
[…]
In noncanonical mode input is available immediately (without the user having to type a line-delimiter character), no input processing is performed, and line editing is disabled. The read buffer will only accept 4095 chars;So this is effectively an OS issue, meaning that either you need to use
base -w4094/base -w $(tput cols)instead ofbase -w0, or do something likewl-paste > file.base64.
REPORTED RESOLVED NOT_OUR_BUG
Comment by ~lanodan on ~lanodan/utils-std
Seems to be related to whether the base64 data is pasted in or redirected in.
Reproduced in:
- foot+tmux with wayland buffer
- foot+tmux with tmux own buffer
- pure foot

Likely could be done with grabbing the function from FreeBSD.

Either via gettext (prior art in doing so in badwolf) or message catalogs (which could be interesting to be less english-centric and probably much more lightweight).

As the GTK3 port of WebKitGTK got deprecated, migration to GTK4 needs to be done. Likely will create one last GTK3 release branch as GTK major changes always come with heavy load of shenanigans for everyone.
