The most current code can be downloaded from Gitlab, and you can also download a release here (which is recommended for most use):
PHP running on Apache can create persistent resource handlers. Consequently, multiple calls to PHP scripts from WPV2 do not require reopening the dirfile and reparsing the format file each time they are called.
Fourteen years ago I wrote a stand-alone program (using Qt) for viewing live dirfile data. It was called palantir, in line with the LOTR naming scheme being used for the BLAST experiment of the day. About eight years ago I made a web-based dirfile viewer for ACT, called the ‘Web Palantir Viewer’ (WPV). The original WPV used a custom-written PHP dirfile reader and updates required page refreshes. WPV2 is the successor to WPV using the official getdata library and AJAX calls instead of page refreshes.
Nobody has actually asked me any questions about WPV2, so there are no frequent questions. Hence, I anticipate possible FAQs with a Q&A.
