I work on high sierra with xcode 9 and have not installed that library.</div><div dir="auto"><br></div><div dir="auto">The LIBRARY_SEARCH_PATH should be overwritten by the xcconfig file, but I will need to check that.</div><div dir="auto"><br></div><div dir="auto">There are 2 projects, but I assume you talk about the kit project?</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div><br></div><div>1. The app doesnt actually attempt to render yet? Were you planning on using CATiledLayer for that? I've used it a couple of times (for PDFs)... it's fun</div></div></blockquote><div dir="auto"><br></div><div dir="auto">No it doesn’t. As you probably have seen the render function is near empty, I am strugling to find out what the tiled calls returns and how to use that in the swift app.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div><div>2. The static lib, and the compiled app, are pretty fat. (At least in debug for the simulator - ~400mb, I havent tried the release build yet). Too fat to embed in my app, it would have to be a separate app. Any insight as to whether this could ever be cut down to a reasonable size?</div></div></blockquote><div dir="auto">Well is it actually quite reduced. LO is simply big.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div><div>3. The link time on the app is outrageously slow at the moment - at least on my macbook pro - I guess this is related to the size and number of symbols in the static lib. That's what the dummy.c file is all about? Needs to be quarantined from the app somehow. Perhaps by keeping it in a Framework project? Or cutting down its size. I was too scared to turn on LTO...</div></div></blockquote><div dir="auto">The link time is my biggest problem, linking the kit is a fraction of linking the app, and It seems to be the swift interface that is the problem.</div><div dir="auto"><br></div><div dir="auto">dummy.c is to link without the kit, and it is automatically quarantined, look in build phases, where you will see it is not being compiled.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div><div>4. Just wondering the reasoning for starting a new C interface into LibreOfficeKit (eg <span style="background-color:rgb(40,43,53);color:rgb(147,201,106);font-family:Menlo;font-size:11px">BridgeLOkit_*</span> )?</div></div></blockquote><div dir="auto">How else would you make a C/C++ interface for swift ?</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div><div>I had success in talking to the main LibreOfficeKit.h file directly from swift by including it in the bridging file. Using it directly would take away a lot of duplication needed to flesh out BridgeLOkit. Granted the main C api isnt that friendly to use, but IMHO it would be better to do the wrapping and making the API friendly on the Swift side, rather than another layer of C, which then still needs swift friendly classes around it. </div><div>The main problem is with the way LibreOfficeKitInit works (which seems weird...), for which I reused <span style="background-color:rgb(40,43,53);color:rgb(147,201,106);font-family:Menlo;font-size:11px">BridgeLOkit_Init</span> and added a func to get the pointer to kit out.</div><div>See the attached LibreOfficeKitWrapper.swift file - it has just a couple wrapped functions done but you can see what I mean. Needs the rest filled in and memory handling done.</div></div></blockquote><div dir="auto">Functions not declared in the bridge are unlikely to work in swift (according to the swift documentation).</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div> <div><br></div><div>I've done this before for Pdfium - which also has a C based FFI. We created a framework called PdfiumSwift which had swift classes like PDFDocument, PDFPage etc which wrapped the C interface and made consuming it easy in Swift. We hooked the memory management off the swift deinit() etc. It used an internal private module to consume the C API so it was just the Swift API exposed outside of the framework / module.</div></div></blockquote><div dir="auto">this is basically the same the kit project does, except it does not use classes.</div><div dir="auto"><br></div><div dir="auto">rgds</div><div dir="auto">jan i</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div></div><div><br></div><div>Once the basic wrapping is done, then these classes provide a good place to add stuff like converting the raw tiles into iOS friendly bitmaps etc.</div><div><br></div><div>Anyway, good job on getting it this far, and happy new year.</div><div><br></div><div>Cheers</div></div><div><div><br></div><div><br></div><div>Jon Nermut</div> </div></blockquote></div></div><div dir="ltr">-- <br></div><div class="gmail_signature" data-smartmail="gmail_signature">Sent from My iPad, sorry for any misspellings.</div>
