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.

Live template: Template:TEMPLATE_NAME
Sandbox: Template:TEMPLATE_NAME/sandbox
Testcases: Template:TEMPLATE_NAME/testcases
Documentation: Template:TEMPLATE_NAME/doc (optional)
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.

{{#if:{{{required|}}} |  <div class="tmpl"> {{{param1|}}} · {{{param2|}}} {{#if:{{{flag|}}}|✓|}} {{#if:{{{raw|}}}|{{{raw}}}|}} </div> |  TEMPLATE_NAME: missing required parameter [[Category:Pages with TEMPLATE_NAME errors]] }}

Skeleton: Template:TEMPLATE_NAME/testcases

; Minimal : {{TEMPLATE_NAME/sandbox}} ; Common params : {{TEMPLATE_NAME/sandbox | param1 = Alpha | param2 = Beta | flag = yes }} ; Edge and escaping : {{TEMPLATE_NAME/sandbox | param1 = [[Linked target|Visible text]] | param2 = 20250101T000000Z | raw = <code>escaped</code> }} ; I18n : {{TEMPLATE_NAME/sandbox | lang = ja | text = こんにちは世界 }} ; Error handling : {{TEMPLATE_NAME/sandbox | required = }}

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.

The data template parameter must be a comma separated list of "JSON" objects. Each object starts with a "{", has a list of comma separated key-value pairs, and ends with a "}". The key may be one of the following values (used no more than once per each object):

Built-in marker shapes
shape	"circle" (default), "square", "cross", "diamond", "triangle-up", "triangle-down" (docs)
color	shape fill color, e.g. "#ff0000" (red - default)
strokeColor	shape outline color
size	shape size (number)
Text labels (see more info)
text	Label text
textAlign	Label's horizontal alignment relative to the marker - "left", "right", "center". By default, left for LTR, right for RTL languages.
textBaseline	Vertical alignment: "middle" (default), "top", "bottom"
textColor	Label text color, e.g. "#ff0000" (red)
textDx, textDy	Horizontal and vertical distance from the marker

font, fontSize, fontWeight, fontStyle	Font name, size, boldness, and style
Image markers
img	URL of an image, e.g. wikirawupload:{{filepath:Volcano red 32x32.svg\|32}}
height, width	Size of the image
offsetX, offsetY	Shift the center of the image on the map

Shows an image of a map, and draws user-specified images/icons on top of it using latitude/longitude coordinates.
