[[Web-authoring::html-preprocessing]]

Seespee: Modified from README.md: Generate or validate a Content-Security-Policy header for a website. The website is crawled for scripts, stylesheets, images, fonts, application manifests etc., which will be listed by their origin. Inline scripts and stylesheets will be hashed so 'unsafe-inline' can be avoided.

Simple Web Error Checker - SWEC: SWEC is a program that automates testing of dynamic websites. It parses each HTML file it finds for links, and if those links are within the site specified (ie. local, not external), it will check that page as well. In this respect it works a lot like a crawler, in that it'll click on any link it finds (more notes about this later). In addition to parsing and locating links, it will also parse the pages looking for known errors and report those (such as Mason or PHP errors), and will report if a page can not be read (by either returning a 404, 500 or similar).

Snippetory: Snippetory is a templating solution for java. It's based on token replacement to keep the templates free from logic. Rendering logic instead is placed in external classes. This creates a clear separation of template code and logic. In addition there is meta-data to describe how the application data is bound to the template.

Spyce: SPYCE is a Web server plugin that supports simple and efficient Python-based dynamic HTML scripting. Those who like Python and are familiar with JSP, PHP, or ASP, should look at this engine. It can generate dynamic HTML content just as easily, using Python for the dynamic parts. Its modular design makes it very flexible and extensible. It supports FastCGI, CGI and mod_python to plugin into Apache and most other Web servers, and can also be used as a command-line utility for HTML pre-processing, or as a web server proxy.

Tea: TEA is a Qt-based editor. Features include a tabbed layout engine, support for multiple encodings, code snippets, customizable hotkeys, Dokuwiki, tools for MediaWiki, Docbook, LaTeX, Lout, Markdown editing, string manipulation functions, bookmarks, syntax highlighting, scripting (Lua, Python, Perl, 2/Rexx, Bash, etc., the built-in file manager. TEA can read/write plain text files and import text from ODT, DOCX, RTF, ABW (Abiword), KWD, FB2, EPUB, PDF, DJVU. Spell check using Aspell and Hunspell engines.

Textpattern: Textpattern is a flexible, elegant and easy-to-use web content management system capable of powering a wide range of websites from a personal blog to full-scale business web sites with a limitless amount of authors, content assets or web pages.

Tree.pl: 'tree.pl' creates a sitemap for all kinds of files (e.g., HTML and image files). It follows the directory structure on disk, creating a nested HTML list that contains the files' names or (in case of HTML) their titles, their last modified date, and their size. It can be used from the command line or as a CGI script.

Untitled: It takes pandoc-flavoured markdown files in website directories, and generates websites in html, using Pandoc. With the use of a Pandoc template, it's quite flexible. It is a *multi-site* static site generator, capable of handling multiple websites in one instance. Perfect for setups with virtual hosts (in nginx, apache etc). It can also generate news sections (with rss feed) and automatically generate sitemaps.

WPP: WPP is a script that preprocesses HTML files. It lets you define "variables", which are brief abbreviations for longer constructs, and include common HTML fragments. It's useful for giving a uniform layout to different HTML pages. It can be used in cgi-bin programs for automatic generation of pages. With less HTML code inside you can make more flexible cgi-scripts.

Wml: WML is an off-line HTML generation toolkit. It is intended for HTML generation under *NIX, for large areas (as opposed to single Web pages), and for those who want to use their favorite programming features while generating HTML. It includes a control frontend driving up to nine backends in a sequential pass-oriented filtering scheme: WML reads an input file, applies the specified passes and produces output files. Each backend provides one particular core language. It also ships with a set of include files which provide higher-level features built on top of the backend's core languages. You can write your own custom HTML tagsets for WML to extend its functionality: whatever HTML tag you want, you can program it yourself in Perl.

Wsmake: Wsmake is a website pre-processor. It includes a parser that handles page ordering, tag substitution, and dependency checking. You can use wsmake with any type of content, from PHP to XML, or even your own computer language. Its goal is to maximize reusability while keeping content separate from design. If there are common elements on each page of your website, the time-savings associated with wsmake will be valuable.

Xidel: Xidel is a command line tool to query data from HTML/XML web pages, JSON-APIs and local files. It implements interpreters for XPath 2, XPath 3, XQuery 1, XQuery 3, JSONiq, CSS selectors and custom pattern matching. XPath and CSS selectors are the most efficient way to select certain elements from XML/HTML documents. JSONiq (with custom extensions) is an easy way to select data from JSON. XQuery is a Turing-complete superset of XPath and allows arbitrary data transformations and the creation of new documents. Pattern matching is for XML/HTML documents what regular expressions are for plaintext, i.e. pattern matching behaves like a regular expression over the space of tags, instead over the space of characters. Xidel implements a kind of internal pipes to pipe HTTP requests from one query to the next, so there is no need to distinguish selecting links and downloading the data referenced by them. Therefore arbitrary complex queries going over arbitrary many pages can be executed with a single call of Xidel.

Xmhtml: The XmHTML Widget Set consists of two widgets: XmHTML, which is a Motif widget that can display HTML 3.2 confirming text, and XmBalloon, a lightweight widget that shows a one line string in a small popup window. There are also a number of routines which lets yo use XmHTML's image support for purposes other than XmHTML.

Youhp3: Youhp3 (Youpee's One Unlimited HTML PreProcessor) is an HTML preprocessor that allows you to embed code of any script language, as well as calling any external program to generate text files. It is specifically designed to work with HTML/XML documents, and provide traditional features, such as define, include, macro, conditional tests, and loop.
