LGTM, although you need to run cargo xtask docgen to update the auto-generated documentation to include the new commands

[vincascm]

thank you for your reply. this is just a set of MappableCommand::Static, even if cargo xtask docgen executed, will not change book/src/generated/typable-cmd.md

Pulls in another dependency :/

[vincascm]

heck has only one dependency : unicode-segmentation = { version = "1.2.0", optional = true }
and did not use by default

[archseer]

Yeah but heck is a new dependency that's pulled in for just a couple commands.

I don't think it's necessary to add commands for this. Converting case is possible to do with just regular editing primitives. The Kakoune introduction docs even use it to show off the power of selections and multiple cursors: https://kakoune.org/why-kakoune/why-kakoune.html#_multiple_selections

[vincascm]

@the-mikedavis consider any conversion between the following 7 cases,

UpperCamelCase
lowerCamelCase
snake_case
kebab-case
SHOUTY_SNAKE_CASE
Title Case
SHOUTY-KEBAB-CASE

if regular editing primitives is used, it is not easy to do.
but these commands can indeed be composed of regular editing primitives, probably lacking a good mapping, between key bindings and a sequence of operations.

[archseer]

If we added macro keybinds then this would be easier to map to a key. A simpler implementation that doesn't pull in heck could also just set the macro register to a sequence of these keys, then execute the macro

[vincascm]

ok, thanks for your replies

I made my own solution after not finding anything satisfactory... Probably also helpful for #5197
