From 923754719a32237a25dd4496bd164b267b4cf4ac Mon Sep 17 00:00:00 2001 From: Doug Kelkhoff <18220321+dgkf@users.noreply.github.com> Date: Tue, 8 Nov 2022 07:19:59 -0500 Subject: [PATCH] Dynamically resize line number gutter width (#3469) * dynamically resize line number gutter width * removing digits lower-bound, permitting spacer * removing max line num char limit; adding notes; qualified successors; notes * updating tests to use new line number width when testing views * linenr width based on document line count * using min width of 2 so line numbers relative is useful * lint rolling; removing unnecessary type parameter lifetime * merge change resolution * reformat code * rename row_styler to style; add int_log resource * adding spacer to gutters default; updating book config entry * adding view.inner_height(), swap for loop for iterator * reverting change of current! to view! now that doc is not needed --- book/src/configuration.md | 2 +- helix-term/src/commands.rs | 16 ++-- helix-term/src/ui/editor.rs | 17 +++-- helix-view/src/editor.rs | 9 ++- helix-view/src/gutter.rs | 57 ++++++++++++-- helix-view/src/lib.rs | 2 +- helix-view/src/tree.rs | 4 +- helix-view/src/view.rs | 145 ++++++++++++++++-------------------- 8 files changed, 143 insertions(+), 109 deletions(-) diff --git a/book/src/configuration.md b/book/src/configuration.md index a704b298d270..407382f728f1 100644 --- a/book/src/configuration.md +++ b/book/src/configuration.md @@ -46,7 +46,7 @@ on unix operating systems. | `line-number` | Line number display: `absolute` simply shows each line's number, while `relative` shows the distance from the current line.
