* fix(latex): prevent LaTeX conversion when closing $ is preceded by backtick
When text contained patterns like "$lookup namespace" followed by "`$lookup`",
the regex would match from the first $ to the backtick's $, treating the entire
span as a LaTeX expression. This caused programming constructs to be incorrectly
converted to double dollars.
- Added negative lookbehind (?<!`) to single dollar regex
- Prevents matching when closing $ immediately follows a backtick
- Fixes issues with inline code blocks containing $ symbols
* fix(latex): detect currency amounts with 4+ digits without commas
The currency regex pattern \d{1,3} only matched amounts with 1-3 initial digits,
causing amounts like $1157.90 to be interpreted as LaTeX instead of currency.
This resulted in text like "$1157.90 (text) + $500 (text) = $1657.90" being
incorrectly converted to a single LaTeX expression.
- Changed pattern from \d{1,3} to \d+ to match any number of initial digits
- Now properly escapes $1000, $10000, $123456, etc. without requiring commas
- Maintains support for comma-formatted amounts like $1,234.56
* fix(latex): support currency with unlimited decimal places
The currency regex limited decimal places to 1-2 digits (\.\d{1,2}), which
failed to properly escape amounts with more precision like cryptocurrency
values ($0.00001234), gas prices ($3.999), or exchange rates ($1.23456).
- Changed decimal pattern from \.\d{1,2} to \.\d+
- Now supports any number of decimal places
- Handles edge cases like scientific calculations and high-precision values
* refactor: Markdown LaTeX processing
- Added micromark-extension-llm-math as a dependency in package.json and package-lock.json.
- Updated Vite configuration to alias micromark-extension-math.
- Modified Markdown components to use singleDollarTextMath: false for improved LaTeX rendering.
- Refactored latex utility functions to enhance LaTeX processing and escaping mechanisms.
* chore: linting of `EditTextPart`
* fix: handle key up to initiate edit of latest user message by adding id prop to Edit Message HoverButton
* chore: linting in Artifact component
* refactor: enhance LaTeX preprocessing functionality
- Updated `preprocessLaTeX` to improve handling of currency and LaTeX expressions.
- Introduced optimized regex patterns for better performance.
- Added support for escaping mhchem commands and handling code blocks.
- Enhanced tests for various LaTeX scenarios, including currency and special characters.
- Refactored existing tests to align with new preprocessing logic.
* chore: filter out false positives in unused packages workflow
- Added a grep command to exclude the micromark-extension-llm-math package from the list of unused dependencies in the GitHub Actions workflow.
* refactor: simplify LaTeX pre-processing for more consistent rendering, disables `singleDollarTextMath`
* refactor: disable singleDollarTextMath in all markdown components
* wip: first pass
* refactor: preserve code blocks and convert rather than preserve LaTeX delimiters
* refactor: remove unused escapeDollarNumber function from latex.ts
