Lazarus IDE plugins

IndySecOpenSSL

This repo provides the IndySecOpenSSL package for both Delphi and Lazarus/fpc. This package provides a new (optional) OpenSSL package separate from Indy's "protocols" package and adds support for OpenSSL 3.0 and later. It may be used as an add-on the Indy 10.6 or the forthcoming Indy 10.7 releases. The IndySecOpenSSL package's purpose is to provide Indy users with an upgrade path to the use of current OpenSSL (3.x) libraries with the minimum of change. This includes users that use the existing version of Indy bundled with Delphi and the version provided with the Lazarus Online Package Manager. For more information on the installation and use of the package please read the comprehensive User Guide provided in the docs subdirectory. New users should pay particular attention to the installation instructions and guidance on installation of the OpenSSL shared libraries (DLLs) included in the User Guide.

Many of the components and classes are stable and have been in development for a number of years. A complete list of library contents and links to documentation is available at https://github.com/delphidabbler/ddab-lib-docs Releases of each sub-project within the library are made separately. These releases are still stored on the Files page here, with each sub-project having its own folder. The Subversion repo here has been left in place as an archive, but is no longer being updated.

Graph Capture

The software was designed for suitable chart creation. From text files or programs, that haven't visual charts themselves, data is passed to "Graph Capture" and plotted there. But you have to write Perl RegEx expressions to extract X and Y-values from raw data. Otherwise, you can request suitable filter templates here https://www.facebook.com/vlad.dubov.77. For making RegEx expressions short docs are also included in the program. You can find "Help: regular expressions in Perl" in the installation folder or in the program's top bar. The program can plot charts from a static file ( just drag and drop the file) or from a dynamically written file - by using a plugin that "connects" to the source. Win 32/64 7/8/10/11 and probably XP ;)
