## Critical Issues

## Fixed Issues
|
||||
|
||||
### 1. Module Import System Not Working
|
||||
### 1. Module Import System Not Working (FIXED)
|
||||
|
||||
**Description:** The `import` statement doesn't appear to work for importing standard library modules.
|
||||
**Description:** The `import` statement wasn't working for importing standard library modules.
|
||||
|
||||
**Example:**
|
||||
```lux
|
||||
import html // Doesn't make html functions available
|
||||
```
|
||||
**Root Cause:** Two issues were found:
|
||||
1. Parser didn't skip newlines inside list expressions, causing parse errors in multi-line lists
|
||||
2. Functions in stdlib modules weren't marked as `pub` (public), so they weren't exported
|
||||
|
||||
**Workaround:** Functions must be defined in the same file or copied.
|
||||
**Fix:**
|
||||
1. Added `skip_newlines()` calls to `parse_list_expr()` in parser.rs
|
||||
2. Added `pub` keyword to all exported functions in stdlib/html.lux
|
||||
|
||||
**Status:** Needs investigation
|
||||
**Status:** FIXED

||||

### 2. Parse Error in html.lux (Line 196-197)
|
||||
### 2. Parse Error in html.lux (FIXED)
|
||||
|
||||
**Description:** When trying to load files that import the html module, there's a parse error.
|
||||
**Description:** When trying to load files that import the html module, there was a parse error at line 196-197.
|
||||
|
||||
**Error Message:**
|
||||
```
|
||||
Module error: Module error in '<main>': Parse error: Parse error at 196-197: Unexpected token: \n
|
||||
```
|
||||
|
||||
**Status:** Needs investigation
|
||||
**Root Cause:** The parser's `parse_list_expr()` function didn't handle newlines between list elements.
|
||||
|
||||
**Fix:** Added `skip_newlines()` calls after `[`, after each element, and after commas in list expressions.
|
||||
|
||||
**Status:** FIXED
|
||||
|
||||
---
|
||||
|
||||
### 3. List.foldl Renamed to List.fold (FIXED)
|
||||
|
||||
**Description:** The html.lux file used `List.foldl` but the built-in List module exports `List.fold`.
|
||||
|
||||
**Fix:** Changed `List.foldl` to `List.fold` in stdlib/html.lux.

||||
**Description:** The `escapeHtml` function in html.lux uses `String.replace`.

# Lux Website
|
||||
|
||||
## Testing Locally
|
||||
|
||||
The website is a static HTML site. To test it with working navigation:
|
||||
|
||||
### Option 1: Python (simplest)
|
||||
```bash
|
||||
cd website/lux-site/dist
|
||||
python -m http.server 8000
|
||||
# Open http://localhost:8000
|
||||
```
|
||||
|
||||
### Option 2: Node.js
|
||||
```bash
|
||||
npx serve website/lux-site/dist
|
||||
# Open http://localhost:3000
|
||||
```
|
||||
|
||||
### Option 3: Nix
|
||||
```bash
|
||||
nix-shell -p python3 --run "cd website/lux-site/dist && python -m http.server 8000"
|
||||
```
|
||||
|
||||
### Option 4: Direct file (limited)
|
||||
Open `website/lux-site/dist/index.html` directly in a browser. Navigation links will work since they're anchor links (`#features`, `#effects`, etc.), but this won't work for multi-page setups.
|
||||
|
||||
## Structure
|
||||
|
||||
```
|
||||
website/lux-site/
|
||||
├── dist/
|
||||

|
||||

|
||||

||||

||||

│ └── generate.lux # Site generator
|
||||
├── LUX_WEAKNESSES.md # Issues found during development
|
||||
└── README.md # This file
|
||||
```
|
||||
|
||||
## Building with Lux
|
||||
|
||||
Once the module system is working (fixed!), you can generate the site:
|
||||
|
||||
```bash
|
||||
./target/release/lux website/lux-site/src/generate.lux
|
||||
```
|
||||
|
||||
The HTML module is now functional and can render HTML from Lux code:
|
||||
|
||||
```lux
|
||||
import stdlib/html
|
||||
|
||||
let page = html.div([html.class("container")], [
|
||||
html.h1([], [html.text("Hello!")])
|
||||
])
|
||||
|
||||
Console.print(html.render(page))
|
||||
// Output: <div class="container"><h1>Hello!</h1></div>
|
||||
```
|
||||
|
||||
## Deployment
|
||||
|
||||
For GitHub Pages or any static hosting:
|
||||
|
||||
```bash
|
||||
# Copy dist folder to your hosting
|
||||
cp -r website/lux-site/dist/* /path/to/deploy/
