Template documentation

Template:Terminate sentence ensures a sentence ends with a specified terminator (default: a period). It avoids adding duplicate terminators and can optionally trim trailing spaces. It attempts to ignore trailing closing quotes or brackets when deciding whether a terminator is already present.

Usage

Basic:

{{Terminate sentence|This is a sentence}}
→ This is a sentence.

Named parameters:

{{Terminate sentence
 |text=He said "Hello"
 |term=.
}}
→ He said "Hello".

Custom terminator:

{{Terminate sentence|text=Warning|term=!}}
→ Warning!

Avoid duplicate terminator:

{{Terminate sentence|text=Already done.|term=.}}
→ Already done.

Trim trailing spaces:

{{Terminate sentence|text=Ends with space   |trim=yes}}
→ Ends with space.

Skip processing:

{{Terminate sentence|text=No changes here|skip=yes}}
→ No changes here

Append a note:

{{Terminate sentence|text=Complete|note=(source: 2025)}}
→ Complete. (source: 2025)

Parameters

1 / text

The input text to terminate.

term

The terminator to enforce at the end. Default is .. Common choices: !, ?.

trim

If yes/true/1, strips trailing spaces before checking.

skip

If yes/true/1, returns text unchanged (still appends note if provided).

allowdup

If yes/true/1, allows duplicate terminators (e.g., ellipses). Default disallows duplicates.

note

Optional text appended after a space, unaffected by termination logic.

Behavior details

• Terminator detection attempts to ignore trailing closing quotes/brackets (", ', ”, ), ], }).
• If the last visible character equals term, no extra terminator is added unless allowdup=yes.
• If trim=yes, trailing spaces are removed before detection.
• If note is present, it is added with a leading space after the final text.

Examples

• Quotes:

{{Terminate sentence|text=He whispered "hush"|term=.}}

 → He whispered "hush".

• Parentheses:

{{Terminate sentence|text=Complete (verified)|term=.}}

 → Complete (verified).

• Exclamation:

{{Terminate sentence|text=Alert|term=!}}

 → Alert!

• Ellipsis (allow duplicates):

{{Terminate sentence|text=Wait...|term=.|allowdup=yes}}

 → Wait....

Best practices

• Prefer using term that matches the sentence intent (., !, ?).
• For complex punctuation, consider the Lua-powered variant below.
• Document usage in your template’s /doc page where you incorporate this helper.

Lua-powered variant (optional)

For more robust detection (including multilingual quotes and punctuation), create Module:TerminateUtil with:

-- Module:TerminateUtil
local M = {}

local closing = {
  [")"] = true, ["]"] = true, ["}"] = true,
  ['"'] = true, ["'"] = true, ["”"] = true, ["’"] = true, ["»"] = true, ["›"] = true
}

local function trimRight(s)
  return (s:gsub("%s+$",""))
end

function M.lastVisibleChar(args)
  local s = args.s or ""
  s = trimRight(s)
  local i = #s
  while i > 0 do
    local c = s:sub(i,i)
    if closing[c] then
      i = i - 1
    else
      return c
    end
  end
  return ""
end

return M

Then update the template to call:

{{#invoke:TerminateUtil|lastVisibleChar|s=text}}

This improves detection for closing quotes and brackets.
