Repair Markdown Math for Consistent Rendering

KaTeX page shows literal `\(...\)`

The site renders $ math fine but a pasted MathJax snippet uses \(...\) and appears as raw text. Target dollar converts it so KaTeX picks it up.

BEFORE (renders as literal text on a KaTeX site):
The limit \( \lim_{x\to 0} \frac{\sin x}{x} = 1 \) is standard.

TARGET: dollar

AFTER (now typesets):
The limit $ \lim_{x\to 0} \frac{\sin x}{x} = 1 $ is standard.

Display equation rendered inline

A \[...\] block sat in the middle of a sentence and rendered inline (or not at all). Target dollar lifts it onto its own $$ block with blank lines, the form block renderers need.

BEFORE:
We minimize \[ J(\theta) = \tfrac{1}{2m}\sum (h-y)^2 \] over theta.

TARGET: dollar

AFTER:
We minimize 
$$ J(\theta) = \tfrac{1}{2m}\sum (h-y)^2 $$
 over theta.

Mixed styles in one help article

An article assembled from several sources mixes $, $$, and \(. Targeting dollar leaves the dollars and converts the strays so everything renders under one renderer.

BEFORE:
Use $p$ for probability, then \( \hat{p} \) for the estimate, with
\[ \text{Var}(\hat p) = \frac{p(1-p)}{n} \]

TARGET: dollar

AFTER:
Use $p$ for probability, then $ \hat{p} $ for the estimate, with

$$ \text{Var}(\hat p) = \frac{p(1-p)}{n} $$

Out of scope: doubled backslashes

Copy-paste sometimes doubles backslashes (\\frac). The tool does NOT unescape these — it only moves delimiters. The equation still fails after a delimiter swap and must be fixed by hand.

BEFORE (escape-damaged):
The ratio \( \\frac{a}{b} \) is wrong.

TARGET: dollar

AFTER (delimiters fixed, LaTeX still broken — fix manually):
The ratio $ \\frac{a}{b} $ is wrong.

Documented delimiter example stays put

A how-to article explains delimiter syntax inside a fenced block. The fence is skipped so the teaching example is preserved while the live prose is fixed.

BEFORE:
Write display math as \[ ... \], for example:
```markdown
\[ a^2 + b^2 = c^2 \]
```

TARGET: dollar

AFTER:
Write display math as 
$$  ... $$
, for example:
```markdown
\[ a^2 + b^2 = c^2 \]
```

If an equation still fails after delimiters match the renderer, the LaTeX content is the problem — an unknown macro, an unbalanced {, or a missing argument. This tool never edits equation content; fix those by hand or in your build's KaTeX error log.

Despite what some copy-paste workflows cause, this tool does not unescape \\frac back to \frac. It only relocates delimiters. Use a find/replace step or fix the source if backslashes were doubled during copying.

Target tex pairs consecutive $ signs, so prose like $10 plan vs $20 plan becomes \(10 plan vs \)20 plan. On docs with pricing or shell $VAR examples in prose, prefer the dollar target, which ignores literal $.

Only ``` fences are protected. A delimiter shown inline like $x$ ` will be converted. When documenting syntax, put it in a triple-backtick fenced block, not an inline span.

~~~ ... ~~~ blocks are treated as prose, so math inside them is converted. Switch teaching examples to ``` ``` fences to keep them verbatim.

The $...$ → \(...\) rule skips spans containing a newline. If an inline formula was accidentally split across two lines, join it first; otherwise it won't convert.

Targeting dollar only adds blank-line surrounds to \[...\] it converts. A pre-existing cramped $$...$$ won't gain blank lines from this tool. If a tight $$ block renders inline, add the blank lines manually or run md-prettifier.

The tool swaps delimiters but leaves the inner math (and its spaces) exactly as written, so \( x \) becomes $ x $. Tidy spacing yourself if your renderer is fussy.

Over 500,000 characters on Free, the input is blocked. A giant API-reference page with thousands of formulas may hit this — upgrade to Pro (5,000,000) or split with md-splitter first.
