Template sandbox and testcases for TEMPLATE_NAME

Overview

This page provides a clean workflow to safely edit and validate TEMPLATE_NAME:

Sandbox: Template:TEMPLATE_NAME/sandbox — a working copy where you make changes.
Testcases: Template:TEMPLATE_NAME/testcases — inputs that exercise typical and edge cases.
Live: Template:TEMPLATE_NAME — the production version. Do not edit directly without review.

Use this page to:

Preview sandbox output against fixed testcases without touching the live template.
Compare actual vs expected output for each testcase.
Track recent changes and invite reviewers.

Sandbox: Template:TEMPLATE_NAME/sandbox
Testcases: Template:TEMPLATE_NAME/testcases

Talk page: Template talk:TEMPLATE_NAME

How to test

1. Edit the sandbox at Template:TEMPLATE_NAME/sandbox. 2. Open this test page and click “Show preview” to render the sandbox with inputs below. 3. Verify each testcase: Does the “Actual output” match the “Expected output”? 4. If all pass, consider copying sandbox to live using an edit summary like:

  “Sync from /sandbox: passes all /testcases as of YYYY-MM-DD.”

Previewing tips

Use “Preview page with this template” gadget or the built-in preview.
Check parser output in different skins and mobile view.
Validate accessibility: headings order, link text, ARIA where applicable.
Internationalization: test with non-ASCII parameters and RTL where relevant.

Test harness

The following sections render the sandbox template against curated inputs. Each testcase shows:

Parameters passed to the template
Expected output (as plain wikitext target)
Actual output (rendered via sandbox transclusion)

Testcase A: Minimal invocation

Parameters: {{TEMPLATE_NAME}}

Expected output: [Minimal successful output with defaults: e.g., a neutral message or basic box]

Actual output (sandbox):

Character and language test sandbox

This sandbox is used to test how Template:TEMPLATE NAME behaves with special characters (such as Greek letters) and language-specific spans.

Basic examples

Greek letter (direct character): α
Greek letter (HTML entity): γ
German span example: A

Within the template

Below are example calls of the template using these characters as parameters.

{{TEMPLATE NAME | title = Greek test: α γ | summary = Demonstrating Greek letters: α, β, γ, and entities like γ. | attr1 = Direct Greek: α β γ δ | attr2 = Entity Greek: α β γ δ | attr3 = German label: A, English label: A }}

Preview the page to check if:

Greek characters (α, β, γ, δ) display correctly.
HTML entities (α, β, γ, δ) render as the expected symbols.
The A is kept as a German-language span and does not break the layout.

Notes

Use this sandbox to experiment with different scripts (Greek, Cyrillic, etc.).
Test right-to-left scripts by adding spans with lang="ar" or lang="he".
If the template trims or escapes some of these, adjust the template code accordingly.

Testcase B: Common parameters

Parameters: {{TEMPLATE_NAME | param1 = Alpha | param2 = Beta | flag = yes }}

Expected output: [Example: shows "Alpha" and "Beta" in designated slots; flag toggles enhanced styling]

Actual output (sandbox):

Copy-paste skeletons

Below are ready-to-use skeletons for the sandbox and testcases subpages.

Review checklist

Output is stable across re-parses; no expensive parser functions without need.
No unexpected categorization in mainspace; errors go to maintenance cats.
Template is documented at Template:TEMPLATE_NAME/doc with parameters, examples, and tracking.
Style is minimal; avoid inline CSS unless necessary; consider using existing module or template styles.

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.

See or edit raw graph data.	See source Wikidata query and sources.
Wikidata query produces three columns - year, population size, and country name. This graph shows one line per country. {{Graph:Lines \| tabletype=query \| table= #Population of countries sharing a border with Germany SELECT ?year ?population ?countryLabel WHERE { { SELECT ?country ?year (AVG(?population) AS ?population) WHERE { { SELECT ?country (YEAR(?date) AS ?year) ?population WHERE { ?country wdt:P47 wd:Q183. ?country p:P1082 ?populationStatement. ?populationStatement ps:P1082 ?population. ?populationStatement pq:P585 ?date. } } } GROUP BY ?country ?year } SERVICE wikibase:label { bd:serviceParam wikibase:language "en". } } \| type=year \| xField=year \| group=countryLabel \| value=population \| title=Population of countries bordering Germany \| legend=- \| xGrid=y \| yGrid=y \| yTicks=7 \| width=600 }}
See source Wikidata query and sources.

This graph draws one or more independent numeric data series as lines. The data must be stored on Commons' Data namespace or come from Wikidata Query Service.
