-- ====================================
-- 1) ARG ACCESS / BARGS WIRING
-- ====================================
local _bargs = nil

function Helpers.setBargs(fn)
_bargs = fn
end

-- If Config.init doesn't call this, Helpers installs fallbacks below.
function Helpers.installArgAccessors(fargs, pargs)

Helpers.getPArg = function(k) return pargs[k] end

end

end

-- Default bargs (so unit tests don’t explode without Config.init)
Helpers.bargs = function(key)
if _bargs then return _bargs(key) end
return nil
end

-- ====================================
-- 2) BASIC CHECKS & YES/NO PARSERS
-- ====================================
function Helpers.isempty(s) return s == nil or s == "" end
function Helpers.notempty(s) return s ~= nil and s ~= "" end

-- tolerant, case-insensitive
function Helpers.yes(val)
if val == nil then return false end

end

if val == nil then return false end

end

-- ====================================
-- 3) STRING HELPERS
-- ====================================
-- 1 -> 'a', 2 -> 'b', ...; wraps beyond 26; clamps nil/invalid to 'a'
function Helpers.toChar(num)
num = tonumber(num) or 1
if num < 1 then num = 1 end
-- wrap to 1..26 to avoid errors if headers exceed 26
num = ((num - 1) % 26) + 1
return string.char(string.byte("a") + num - 1)
end

-- Escape single characters for use inside a Lua pattern character class.
local function _esc_cc(ch)
-- dash, caret, percent, closing bracket need escaping inside [...]
if ch == "-" or ch == "^" or ch == "]" or ch == "%" then
return "%" .. ch
end

end

-- Fast split over single-char delimiters; drops empties; optional number-cast.
function Helpers.split(str, delim, tonum)
if Helpers.isempty(str) then return {} end
local result, buf = {}, {}

-- 2) Wrap balanced (...) and [...]
text = text:gsub("(%b())", function(m) return string.format(STYLE_NORMAL, m) end)

-- 3) Restore wikilinks
for key, link in pairs(placeholders) do
text = text:gsub(key, "[[" .. link .. "]]")
end
return text
end

-- ====================================
-- 4) STYLE & DIMENSIONS
-- ====================================
-- Border mask is {top, right, bottom, left}
function Helpers.cellBorder(b)
-- assume well-formed input; callers always pass 4 numbers
return b[1] .. "px " .. b[2] .. "px " .. b[3] .. "px " .. b[4] .. "px"
end

-- Normalize CSS length: numbers -> "Npx"; strings with units pass through.
function Helpers.toCssLength(v, defaultVal)
if v == nil or v == "" then return defaultVal end
local n = tonumber(v)
if n then return tostring(n) .. "px" end
return v
end

-- Resolve widths from args with normalization & default
function Helpers.getWidth(ctype, defaultVal)
local raw = Helpers.bargs(ctype .. "-width")
return Helpers.toCssLength(raw, defaultVal)
end
