# singlechar.vim - Insert single characters without entering insert mode
# Author: lohhiiccc
# Version: 0.1
# Version: 1.0.0
# License: MIT
# Repository: https://github.com/lohhiiccc/vim-singlechahttps://github.com/lohhiiccc/vim-singlechar
# ------------------------------------------------------------------------------ #
# Description:
# This plugin allows you to quickly insert a single character without entering
# insert mode. Simply use the configured mapping, press the character you want
# to insert, and continue in normal mode. Supports count for repeating characters.

# Options
# Configuration options
# Mapping to insert a character at cursor position (before cursor)

g:singlechar_map_insert_at = '<Leader>i'

# Mapping to insert a character after cursor position

# Core functionality
# Function to handle character insertion
# Parameters:
# mode: 'at' to insert before cursor, 'after' to insert after cursor
# count: number of times to repeat the character

# Commands and mappings
# Direct command implementations
command! -count=1 -nargs=0 InsertCharAt InsertChar('at', <count>)
command! -count=1 -nargs=0 InsertCharAfter InsertChar('after', <count>)
# Create default mappings unless disabled

execute "nnoremap <silent> " .. g:singlechar_map_insert_after .. " <ScriptCmd>echo InsertCharSilently('after')<CR>"
execute 'nnoremap <expr> <silent> ' .. g:singlechar_map_insert_at .. ' ":<C-u>InsertCharAt " .. v:count1 .. "<CR>"'
execute 'nnoremap <expr> <silent> ' .. g:singlechar_map_insert_after .. ' ":<C-u>InsertCharAfter " .. v:count1 .. "<CR>"'
endif
# Usage:
# <Leader>i - Insert character at cursor position
# <Leader>a - Insert character after cursor position
#
# You can use a count before the mapping to insert multiple copies
# of the same character. For example: 3<Leader>i will insert the
# character 3 times at the cursor position.
