Migrated to https://codeberg.org/anaseto/gruid-tcell because of new 2FA requirement
The gruid-tcell module provides a gruid Driver for building terminal full-window applications.
The provided driver tcell package depends on the tcell terminal library, which uses the permissive enough Apache License v2. The library is pure Go, so no special steps are required to install it, and it allows for easy cross-compilation.
You only need to look into the tcell.Style type documentation to define the
styling that has to be used by the Driver.
Note that the terminal grid is not a true grid: some characters are two-cell wide (such as wide east-asian characters). The character width can be computed thanks to the go-runewidth package, so it can be taken into account, but it is a bit cumbersome and ad hoc with respect to the graphical drivers which could handle this problem more easily (the tile width can be adjusted to fit any wanted character). Currently, runes with zero value are ignored by this terminal driver, so they can be placed after a wide character. A portable solution is to always pass wide-characters twice, but with different attributes, and then handle this in each driver, either replacing the second one with a zero rune (for this driver), or a different image (for graphical drivers).
