A few ways to grab diagnostic text in Helix:

1. Hover popup (easiest) — Space + k

Position cursor on the problematic line and press Space + k. The full diagnostic message appears in a floating window. Select the text with v then yank with y.

2. Diagnostics picker — Space + d

Opens a list of all diagnostics in a picker. You can read the full message there. Navigate with arrow keys and Enter to jump to the location.

3. Jump and read from statusbar

Use ]d / [d to jump between diagnostics. The short form appears in the status bar; Space + k at that position gives the full text.

4. Pipe to clipboard via shell

If you need to batch-copy all diagnostics, write them via the LSP log. In ~/.config/helix/config.toml:

[editor]
log-level = "info"

Then check ~/.cache/helix/helix.log — all diagnostic messages from the language server are logged there and easy to copy.

The Space + k hover route is the most direct for a single diagnostic.

thanks for that, but

1. the Space + k didn't show up a popup window when done on a line with diagnostics
2. i can see a picker window for diagnostics but i can't seem to figure out how to copy the contents
3. still the same issue as 2nd

i found a helix command, its called yank-diagnostic and it copies the diagnostic where the edit cursor currently is

but its still a little combursome to type a command eveytime

use the :yank-diagnostic command to copy the current diagnostic to your clipboard. You can probably check your binding for it via space+? and typing the command's name in.
