What is Tempcode, and how is it used in website themeing?
Answer
Tempcode is a templating language used within Composr. It offers a powerful way to control the output of dynamic content and design elements on a website. It works by using:
Parameters: Placeholders for content passed to the template from Composr / PHP.
Symbols: Global functions that perform operations, calculations, or retrieve information.
Directives: Instructions that control the flow or logic of content, such as conditional statements and loops.
Language strings: References to pre-defined text stored in language files for easy translation.
Escaping: Ensures the content generated is properly escaped according to its use case.
Tempcode empowers theme designers to create highly customizable and dynamic websites, allowing for logic, conditional rendering, and manipulation of various website elements.
How can design elements like dominance and attention to detail improve a website?
Answer
Dominance and attention to detail are key to a balanced and engaging website. Important elements can be emphasized using techniques like larger text, unique colors, and increased spacing. Conversely, less crucial elements should receive less emphasis. This interplay helps guide the visitor's eye and ensures a visually harmonious layout.
Attention to detail involves eliminating inconsistencies and distractions, such as typos, misaligned elements, and low-quality images, that can detract from the overall aesthetics and message of the website.
What is the importance of color schemes in website design?
Answer
Color schemes are crucial as they convey emotions and brand identity. Choosing colors that align with your website's purpose can evoke desired feelings in visitors. For example, a website selling chocolates might use shades of brown to subconsciously trigger associations with chocolate. However, an environmental website would be better suited using green, aligning with pre-existing perceptions of environmentalism.
It is also important to maintain consistency with your color scheme, limiting the number of colors used to avoid a conflicting and cluttered appearance.
Can I use Comcode / resource IDs directly when working with the repository?
Answer
Using Comcode / resource IDs directly is not recommended as they may not match between different sites. Use GUIDs instead, which Composr automatically substitutes for IDs before parsing Comcode. You can use Commandr commands like find_guid_via_id to find the GUID for specific resources.
You can access the repository using WebDAV (non-bundled addon), which allows you to view it as a folder on your computer. Composr uses the SabreDAV PHP library for WebDAV functionality. However, please be aware that SabreDAV is deprecated and may not function correctly on newer PHP versions.
The repository is structured as a filesystem with various meta-filesystems mounted under a root directory. These meta-filesystems include:
bin: Stores Commandr scripts.
database: Provides access to the raw database.
etc: Allows access to Composr configuration options.
home or filedump: Provides access to the File/Media Library.
home contains the files in a special JSON format with metadata
filedump contains the raw files
members: Lists registered members with their settings and user groups.
raw or root: Provides access to the Composr installation directory.
raw contains the raw files without overrides, and modifying any file modifies them directly without automatic override handling
root contains the files with applicable overrides applied automatically, and Composr will automatically handle overrides and utilizing _custom directories when these files are modified
var: Contains structured website resources and content.
How do I set the correct file permissions for Composr?
Answer
If you're using the quick installer, it will handle file permissions automatically. On a suEXEC-style server, default permissions (744 for directories and 644 for files) are usually sufficient. However, _config.php should have 600 permissions for security.
Without suEXEC, specific directories (e.g., caches, uploads) and files (e.g., _config.php) require 777 (full access) or 666 (read/write) permissions. The fixperms.php script can automate this process on Linux and Windows.
What are the prerequisites for installing Composr?
Answer
Before installing Composr, ensure your web host meets the minimum requirements. Familiarize yourself with your web host's control panel (e.g., Plesk, cPanel), which you'll use to manage databases, subdomains, and other settings. Gather your SFTP/FTP credentials (hostname, username, password), usually emailed upon signup. Set up a MySQL database and note its details: hostname (often 'localhost'), username, password, and database name. Ensure the database user has full read/write/administer access to the database.
What tools are available for debugging Composr code?
Answer
Composr offers a code quality checker addon that helps identify various types of errors, including parser errors, run-time errors, and logical errors. This tool can significantly reduce debugging time and enhance code reliability. It is available through the testing_platform addon.
Composr emphasizes clean, well-structured code with a focus on readability and maintainability. Key standards include proper indentation, consistent use of comments, and clear function headers with type definitions. Remember: beautiful code leads to better functionality and collaboration!
The Code Editor is a web-based tool for editing Composr code files directly on the server. It requires password authentication and automatically manages overrides within _custom directories.
Composr allows exporting addons as TAR files, containing all necessary files and an addon.inf file for metadata. You can import these addons to share and reuse them across different Composr installations.
To do this, make your necessary files for the addon in the Composr installation, and then go under Admin Zone > Structure > Addons > Export addon. You can select the relevant files for the addon, provide information about the addon, and then download the TAR file (which can then be imported on other Composr sites).
