# Changelog for Lx

## Aug 25, 2026

### Features

- MaLxTeX names *Lx's* native KaTeX-compatible Markdown math renderer
- `md-preview:render-images` renders the complete document as numbered PNG pages beside its Markdown file without leaving obsolete pages from longer exports; `config.plugins.mdpreview` controls output
- Document views show current or estimated content size beside line count
- Status bar shows `Spaces` or `Tabs`, marks automatic sizes with `*`, and cycles through `config.indent_size_cycle`
- `doc:detect-indent` rescans current document and restores automatic type and size
- `doc:use-spaces` and `doc:use-tabs` select future indentation
- `doc:to-spaces` and `doc:to-tabs` convert leading indentation across the document as one undoable edit
- Middle-clicking indentation status restores automatic detection; *Alt*-clicking toggles future indentation between spaces and tabs

### Improvements

- Lx is now distributed under the Lx Interim License. See LICENSE file for details.
- License files for libraries are now packaged with the program
- LuaPad scripts can directly use `core`, `config`, `command`, `common`, and the view used immediately before LuaPad as `previous_view`
- FPS overlay feature is now accessible via `config.fps_overlay`
- Indentation settings now use `indent_type = "spaces"` or `"tabs"`
- Markdown box drawings, including drawings inside fenced and indented code, use connected monospace rows enabled
- Markdown outline may be toggled automatically when maximized or fullscreen

### Fixes

- `\mathchoice` renders only the branch for the active display, text, script, or scriptscript style
- `\mathscr` uses its own script face instead of matching `\mathcal`, while `\mathfrak` keeps its distinct Fraktur alphabet
- Fraction rules stay clear of visibly drawn limits inside `\smash`
- Markdown blockquotes leave clear space before following content
- `doc:delete-lines` stops on an empty final row instead of continuing upward through the remaining document
- Formats chosen with `doc:set-format` stay selected after saving, including when the filename suggests another format
- Automatic indentation samples throughout larger documents instead of letting an unrepresentative opening section decide the result

## Aug 18, 2026

### Features

- `lines:stride`, `lines:reduce`, and `lines:sample` keep repeating, evenly spaced, or random subsets of lines
- `file:select-under-cursor`, `file:select-first-in-line`, `file:select-all-in-line`, and `file:select-all-visible` toggle confirmed enclosed, prefixed, Markdown-link, or source-located references (depends on format module)
- `file:open-under-cursor` opens a confirmed reference or an existing naked path at cursor, and `file:open-first-in-line` opens the first confirmed reference on the current line; both apply locations without moving the source cursor
- `navigate:back` and `navigate:forward` move between file reference source and destination positions, including selections, panes, and scroll positions
- Holding *Ctrl* or *Cmd* gently reveals confirmed visible file references as clickable links without moving or accidentally selecting source text
- `config.file_reference_links` can turn file reference links off
- File references search `config.file_reference_search_paths` and can use one unambiguous exact match from the existing project index
- CMake file references recognize direct include, source directory, and configure input arguments; source directories open their `CMakeLists.txt`
- C# file references recognize local `#load`, `#r`, `#line`, and checksum directive targets
- CSS file references recognize local quoted or simple unquoted `url(...)` values and quoted `@import` targets while ignoring browser-only targets
- HTML file references recognize local targets in common quoted link, media, object, and form attributes while ignoring web URLs and page-only anchors
- `.htaccess` file references recognize literal local files in direct file-taking directives, including `HeaderName` and `ReadmeName`, without treating rewrite URLs as files
- Java file references recognize direct imports and static member imports as source filenames
- JavaScript file references recognize relative static, dynamic, exported, and CommonJS module targets, including extensionless file and `index` alternatives
- Lua file references recognize literal `require`, `dofile`, and `loadfile` targets; module names try both `.lua` files and matching `init.lua` files
- GNU Make file references recognize plain filenames in `include`, `-include`, and `sinclude` directives
- Go file references recognize literal `//go:embed` files and cgo include targets
- PHP file references recognize literal `include`, `include_once`, `require`, and `require_once` targets
- Pascal file references recognize `uses` units, explicit unit files, and compiler includes
- Perl file references recognize literal quoted files passed to standalone `require` and `do`
- Python file references recognize dotted modules in direct `import` and `from` statements, including package-relative module and `__init__.py` alternatives
- Rust file references recognize external `mod name;` declarations with module-file alternatives, literal include macros, and explicit `path` attribute targets
- Sass file references recognize local `@use`, `@forward`, and `@import` targets with partial and index alternatives
- Shell file references recognize literal `source` and `.` command targets at clear command positions
- Visual Studio solution file references recognize project entries and simple solution items

- `config.dev.show_details` and `dev:toggle-details` show headed reports with complete startup and document-opening facts, individual stage times, and every folder checked while opening file references

### Improvements

- `lines:*` commands consistently use every selected line block, or whole document when nothing selected
- Missing file references flash their source line red without replacing the current status message
- File reference help explains paths, exact file locations, virtual paths, selection actions, and opening behavior in one place
- Format file-reference rules can use `caseless = true` for readable case-insensitive prefix and path patterns
- Core developer, file, zoom, and quote helpers use the clearer `core.dev.*`, `core.file.*`, `core.ui.zoom`, and `core.text.quotes` module paths

### Fixes

- Syntax highlighting catches up immediately after jumping to a distant part of a long file
- JavaScript and TypeScript file-reference rules load from the JavaScript format module instead of being discovered as a separate format
- File references retry missing slash-rooted paths without the leading slash; PHP also recognizes quoted path pieces inside concatenated inclusion expressions
- `config.highlight_word_under_cursor` highlights matching copies of the word under the cursor, including numeric words; selection matching is opt-in through `config.highlight_selection_matches`
