vim: Add gdefault setting to set /g as a default substitution flag - #47664
Merged
Conversation
vim has a `:set gdefault` flag, which is described as follows:
'gdefault' 'gd' boolean (default off)
global
When on, the ":substitute" flag 'g' is default on. This means that
all matches in a line are substituted instead of one. When a 'g' flag
is given to a ":substitute" command, this will toggle the substitution
of all or one match. See complex-change.
command 'gdefault' on 'gdefault' off
:s/// subst. all subst. one
:s///g subst. one subst. all
:s///gg subst. all subst. one
After using vim for years with this flag it is hard to remember to add
`/g` all the time, and I think this setting is convenient. So add
support for this flag under `vim.gdefault`.

- Update `vim::normal::search::Replacement.parse` to correctly handle the case where multiple `g` flags are provided, where each one should invert the effect of a previous one, similar to what Neovim does - Update documentation in `settings_content.VimSettingsContent.gdefault` so it shows for users while editing the settings file - Update the `test_replace_gdefault` test to use `NeovimBackedTestContext` instead of `VimTestContext` so we actually test against Neovim's behavior

@bluetech Thank you for picking this one up and including tests! 🙌
I've pushed two smaller commits that add:
- Support for
:set [gd]defaultand:set [nogd]efaultin Zed's command palette - Documentation in
VimSettingsContentso that it shows while user's are editing the settings file - Update the test to use
NeoVimBackedTestContextso that we actually test against Neovim's behavior
Will just run this over someone else in the team to ensure that we're ok with using gdefault for the setting name, but it's looking good. Thank you so much! 🙂

zed-industries#47664) Add support for Vim's `gdefault` option which makes the `:substitute` command replace all matches in a line by default, instead of just the first match. When enabled, the `/g` flag inverts this behavior. - Add `vim.gdefault` setting - Add `:set gdefault`, `:set nogdefault` (and short forms `:set gd`, `:set nogd`) - Fix handling of multiple `/g` flags so that each one inverts the one before Closes zed-industries#36209 Release Notes: - vim: Add `vim.gdefault` setting to make `/g` (replace all matches in a line) the default for substitutions, along with `:set gdefault` and `:set nogdefault` commands (short forms: `gd`, `nogd`) --------- Co-authored-by: dino <dinojoaocosta@gmail.com>
