问题 I am trying to get the version of jQuery a page is using in an alert. It works perfect: I use alert(jQuery.prototype.jquery) Now my question is what is the difference between jQuery and jquery words here that are specified before and after prototype. which one is specified by $. 回答1: The global $ and jQuery variables just point to the same function object, they are "aliases". jquery is just the name of the property of the prototype object. The two names have nothing to do with each other -

问题 I'm receiving an error due to the fact I'm attempting to use the app indexing library from Google while also importing a library which uses an older version of the android gms library for a different component - the cast library from Google Play services. The error states " All com.google.android.gms libraries must use the exact same version specification(mixing versions can lead to runtine crashes). Found versions 8.30,7.80. Examples include com.google.android.gms:play-servics-appindexing:8

问题 In a big project while former developers already worked on, you can find dependencies in gradle that doesn't have any usages at all. Do those dependencies affect apk size? and how dependencies affect apk size, what if you're just using one method from a library, does this mean that all the library files attached to your apk . 回答1: Yes, unused dependencies do increase the apk size. Enabling minifyEnabled true can analyze all the bytecode and remove unused classes and methods. buildTypes {

问题 Here is my try: IF (NOT WIN32) #INSTALL_TARGETS(${LIB_INSTALL_DIR} ${tinyscheme-nix_BINARY_DIR}/libtinyscheme.so) #INSTALL(TARGETS ${tinyscheme-nix_BINARY_DIR}/libtinyscheme.so DESTINATION ${LIB_INSTALL_DIR}) ENDIF() Both variants are wrong. I want to move libtinyscheme.so from ${tinyscheme-nix_BINARY_DIR} to /lib or /lib64 . Basically, I think ${LIB_INSTALL_DIR} handles it. How can I make it? Where is my mistake? 回答1: You probably want the FILES version of install here instead of the TARGETS

问题 I'm rewriting my Windows C++ Native Library (an ongoing effort since 2002) with public release in mind. For the past 10 years I've been the sole beneficiary of those 150+ KLOC and I feel others might find good uses for it also. Currently the entire library is quite-templated and header only. That means all code is in the body of the classes. It's not very easy to manage but it's OK. I'm VERY tempted, after reading several C++ library coding guidelines, to break it into .hpp + .inl files.

问题 After having false starts with poco's zip and minizip (both have issues, minizip can't decompress files larger than 2gb and poco zip corrupts any zip file larger than 2 gigs it compresses) I was wondering if there was anything else left? So any suggestions for a C++ archive library that can handle zip AND zip64? 回答1: 7-zip handles both, as far as I could tell from a quick glance at their source code. It's also LGPL, which should allow its use in a closed source app. 回答2: Well there is the all

问题 I've seen several posts addressing this topic in regards to iOS, but the one or two mentions of OS X just say to build a framework instead of a static library. (I can't find the post that had decent framework instructions.) I've created my project as a static library, and coded the whole thing up accordingly. Now, I simply want to put my framework in a demo app and it's complaining about a missing nib. As a stopgap, I've copied the nib into the parent project, but I want to properly

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Where can I get a fast linear system solver written in D? It should be able to take a square matrix A and a vector b and solve the equation Ax = b for b and, ideally, also perform explicit inversion on A . I have one I wrote myself, but it's pretty slow, probably because it's completely cache-naive. However, for

问题 How to make a python file, which installs the mentioned python packages, on running that python file in console instead of installing packages one by one as we do by using pip I am also confused with setup.py is it same and if it is how to do please help 回答1: You can make one text file which has your name of package requirements.
