keep (cursor) position when exactly replacing text (#5930)
Whenever a document is changed helix maps various positions like the
cursor or diagnostics through the `ChangeSet` applied to the document.

Currently, this mapping handles replacements as follows:

* Move position to the left for `Assoc::Before` (start of selection)
* Move position to the right for `Assoc::After` (end of selection)

However, when text is exactly replaced this can produce weird results
where the cursor is moved when it shouldn't. For example if `foo` is
selected and a separate cursor is placed on each character (`s.<ret>`)
and the text is replaced (for example `rx`) then the cursors are moved
to the side instead of remaining in place.

This change adds a special case to the mapping code of replacements:
If the deleted and inserted text have the same (char) length then
the position is returned as if the replacement doesn't exist.

only keep selections invariant under replacement

Keeping selections unchanged if they are inside an exact replacement
is intuitive. However, for diagnostics this is not desirable as
helix would otherwise fail to remove diagnostics if replacing parts
of the document.

Screenshot

A Kakoune / Neovim inspired editor, written in Rust.

The editing model is very heavily based on Kakoune; during development I found myself agreeing with most of Kakoune's design decisions.

For more information, see the website or documentation.

All shortcuts/keymaps can be found in the documentation on the website.

Troubleshooting

Features

  • Vim-like modal editing
  • Multiple selections
  • Built-in language server support
  • Smart, incremental syntax highlighting and code editing via tree-sitter

It's a terminal-based editor first, but I'd like to explore a custom renderer (similar to Emacs) in wgpu or skulpin.

Note: Only certain languages have indentation definitions at the moment. Check runtime/queries/<lang>/ for indents.scm.
