macOS FPC + Lazarus daily snapshots

IGNORE THE BIG GREEN DOWNLOAD BUTTON: choose file in Files area These macOS snapshots of the development branches are generated automatically. All I can say is that the compiler found the source good enough to compile. YOU ARE USING COMPLETELY UNTESTED SOFTWARE. Caveat Utilitor! 1. Move lazarus-src to your home directory 2. Open a Terminal 3. Change to lazarus-src and run the command: xattr -drv com.apple.quarantine * 4. Use a script to start Lazarus like: #!/bin/sh open ~/lazarus-src/lazarus.app --args "--pcp=~/.laz_main" There is also a daily FPC development snapshot for ARM64. 1. Move fpc-src to your home directory 2. Install with a script like: #!/bin/sh cd ~/fpc-src xattr -drv com.apple.quarantine * sudo make FPC=$PWD/ppca64 OPT="-ap -FD/Library/Developer/CommandLineTools/usr/bin -XR/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk" install Adjust links in /usr/local/bin to point to 3.3.1 or choose compiler in Lazarus

Delphi Cross-Platform Application Help

On the surface, Ziphelp is basically HTML in a compressed zip archive, hence the name. Pack any folder with HTML files into a zip archive and you are good to go. But Ziphelp is more than that, it is a protocol based on the standard sitemap protocol, designed to give a help viewer (here: the Delphi implementation) extended information about the content of the help system. That is help context numbers, help keywords, associative keywords, page titles. This information is missing in a standard sitemap.xml. Ziphelp extends the sitemap protocol and enables direct communication of an app with the help system. The Ziphelp protocol is not just for zip archives. It works inside an archive, with uncompressed folders or with HTML content loaded directly from a website. A Delphi desktop app may be deployed with local application help, uncompressed, zipped or embedded. A mobile or web application might not ship with local HTML content, but refer to an online version instead.

TemplateApp

Lazarus template application project with full localization. It took me quite some time to create a fully featured application project that could set the language from the system but also had the capability to set the language live from the application itself. Templating is good. It saves time because you don't have to reinvent the wheel and it prevents bugs because what you already have is probably already tested. See /help/index.html or the wiki page for further information.
