Junegunn Choi 083045ad53 Clarify comment on height overestimation 2026-07-18 00:52:44 +09:00
Junegunn Choi 235ef3c95c Compute separator length once in printInfoImpl
separatorLength now derives value from window layout on each call;
hoist to local as it cannot change within single repaint

Junegunn Choi f7f8b35f6c Check threshold alternatives for preview at 'next' position
Alternative layout in --preview-window spec can also place preview next
to input section, e.g. 'up,40%,<30(next)'

Junegunn Choi e098a796bb Ignore inline header border when hiding separator
Inline header is drawn inside list border, not adjacent to input
section. Decide based on section actually next to input: header lines
window or list border.

  # Bare header lines next to input; separator needed
  fzf --list-border --header foo --header-lines 2 \
      --header-border inline --header-lines-border none

Junegunn Choi a62fc80f1a Keep separator when preview window is at 'next' position
Preview window at 'next' position sits right next to input section, so
border of header or list section is not adjacent to it. Suppressing
separator there left no divider when preview border is none.

Junegunn Choi 5e31fd25e7 Hide default separator when a border separates input from list
- Applies when adjacent section (header, header lines, or list) draws
  border line facing input section

    # No separator below header border
    fzf --style full --input-border none --header foo

    # Separator shown; nothing separates input from list
    fzf --style full --input-border none --header foo --no-header-border

- Evaluated dynamically so change-header/toggle-header update it

------
- The default separator on the info line is no longer shown when the input section is already visually separated from the list section by a border line
```sh
# No separator shown below the header border
fzf --style full --input-border none --header foo
# Separator shown; no border separates the input section from the list section
fzf --style full --input-border none --header foo --no-header-border
```
- Rendering improvements
- Each frame is now wrapped in synchronized update mode (mode 2026) to reduce flickering on supported terminals
- Reduced rendering output by 10-23% by skipping redundant SGR sequences
