The main issue we have to worry about is sometimes file completion will want to be local, and sometimes we will want to use the platform. For example the "target create" command probably wants to use local paths, and other commands might want the platform. It would be interesting to see all of the places this completion is used and see if we can easily classify them into local or platform, or some might want both?</div><div><br class=""></div><div>It would be easy to move the llvm::sys file system calls into the host platform code if we were to make this happen.</div><div><br class=""></div><div>Greg</div><div><br class=""><blockquote type="cite" class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class=""><div class=""><font class=""><span style="caret-color: rgb(0, 0, 0);" class=""><br class=""></span></font></div><div class=""><font class=""><span style="caret-color: rgb(0, 0, 0);" class="">Best regards,</span></font></div><div class=""><font class=""><span style="caret-color: rgb(0, 0, 0);" class="">Gongyu Deng</span></font></div></div>_______________________________________________<br class="">lldb-dev mailing list<br class=""><a href="mailto:lldb-dev@lists.llvm.org" class="">lldb-dev@lists.llvm.org</a><br class="">https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev<br class=""></div></blockquote></div><br class=""></body></html>
