From 5b0e381a261b1450735f4eddac55aeb956c13713 Mon Sep 17 00:00:00 2001 From: Josh Rahm Date: Sun, 21 Aug 2022 22:01:00 -0600 Subject: feat(userreg): Add user-defined registers to Neovim. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change unlocks additional registers for Neovim by allowing a user to define their own behavior for non-builtin registers. This is accopmlished through a new option 'userregfunc' The 'userregfunc' defines the function to call when handling a register for which there is no builtin functionality. The 'userregfunc' function should take 3 arguments: action - Either "yank" or "put" register - The character corresponding to the register content - In the case of action == "yank", the dictionary describing the yanked content, with the following keys: {type} - Either "char", "line" or "block" {lines} - The lines being yanked as a list {width} - The width in case of "block" mode. {additional_data} - Additional data (can be returned in "put" mode) In case of "put" this function should return the content to put. This content can be either: * A dictionary in the same template as content above. * A list of strings. This will be assumed to be "line" mode. * A string. This will be assumed to be "char" mode. An example of a "null" 'userregfunc' that provides an implementation identical to traditional vim registers would be: let s:contents = {} function! MyUserregFunction(action, register, content) abort if a:action == "put" return get(s:contents, a:register, "") else let s:contents[a:register] = a:content endif endfunction set userregfun=MyUserregFunction It is important to note that any valid unicode character can now be a register, including something like @☺. This change also addresses the multibyte parsing issues surrounding let @a = 'xyz' let @🔨 = 'hammer' --- src/nvim/options.lua | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src/nvim/options.lua') diff --git a/src/nvim/options.lua b/src/nvim/options.lua index 2f941f5d0c..89de495d7a 100644 --- a/src/nvim/options.lua +++ b/src/nvim/options.lua @@ -2690,6 +2690,15 @@ return { varname='p_ut', defaults={if_true=4000} }, + { + full_name='userregfunc', abbreviation='urf', + type='string', scope={'buffer'}, + secure=true, + vi_def=true, + alloced=true, + varname='p_urf', + defaults={if_true=""} + }, { full_name='varsofttabstop', abbreviation='vsts', short_desc=N_("list of numbers of spaces that uses while editing"), -- cgit From 242f75745009b3a0a2108d98ce6c02b6e13aac3f Mon Sep 17 00:00:00 2001 From: Josh Rahm Date: Sun, 21 Aug 2022 23:12:54 -0600 Subject: feat(userreg): normalize userregfunc option format --- src/nvim/options.lua | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/nvim/options.lua') diff --git a/src/nvim/options.lua b/src/nvim/options.lua index 89de495d7a..044054916b 100644 --- a/src/nvim/options.lua +++ b/src/nvim/options.lua @@ -2692,10 +2692,8 @@ return { }, { full_name='userregfunc', abbreviation='urf', + short_desc=N_("Function used to define behavior of user-defined registers."), type='string', scope={'buffer'}, - secure=true, - vi_def=true, - alloced=true, varname='p_urf', defaults={if_true=""} }, -- cgit
