问题 I have a function which looks like this: template <typename T, std::size_t... I> std::ostream& vector_insert(std::ostream& lhs, const char* delim, const T& rhs, std::index_sequence<I...>) { std::ostream_iterator<float> it(lhs, delim); ((*it++ = at(rhs, I)), ...); return lhs; } This is my final attempt and I'm still failing on my expansion of the integer_sequence I'm hoping someone can tell me how to write a line that will effectively expand to: *it++ = at(rhs, 0U), *it++ = at(rhs, 1U), *it++

问题 I have python 2.7 and am trying to issue: glob('{faint,bright*}/{science,calib}/chip?/') I obtain no matches, however from the shell echo {faint,bright*}/{science,calib}/chip? gives: faint/science/chip1 faint/science/chip2 faint/calib/chip1 faint/calib/chip2 bright1/science/chip1 bright1/science/chip2 bright1w/science/chip1 bright1w/science/chip2 bright2/science/chip1 bright2/science/chip2 bright2w/science/chip1 bright2w/science/chip2 bright1/calib/chip1 bright1/calib/chip2 bright1w/calib

问题 I'm following dev guide at http://developer.android.com/guide/market/expansion-files.html in order to download additional assets to my apk. I've done all the part about the importation of libraries, etc .. I've also implemented the samples code in my main program (in order to detect if expansion files are already downloaded, if we need to download them and launch the download, etc ..) I have no errors in eclipse, but when I launch the app and starting to call the methods and classes from the

问题 I understand that the wildcard * (by itself) will expand in such a way that it means "all non-hidden files in the current folder" with hidden files being those prefixed by a period. There are two use cases that I would think are useful, but I don't know how to properly do: How can you glob for... "All files in the current folder, including hidden files, but not including . or .. "? How can you glob for... "All hidden files (and only hidden files) in the current folder, but not including . or

问题 I've got a YAML file with nodes such as: group: name: test permissions: - i.can.(create|delete) I need to replace i.can.(create|delete) with i.can.create and i.can.delete (there are many instances). How can I do this easily? 回答1: The idea is to replace all something(a|b|c|...) with lines somethinga somethingb etc. awk seems to be suited here more than sed: awk 'BEGIN { FS="[(|)]" ; OFS=""} /\(.*\)/ { for (field=2;field<NF;field++) {print $1,$field ;} ; next ; }1' This will do what you wanted

问题 I have an android app that displays maps. The maps are hi-res images sliced to 100 tiles per map to maintain resolution. I currently have each map in a separate folder in my assets folder. As this makes my apk huge, I want to move these images to my main apk expansion file. Currently I am displaying the images in a webview using the following code to stitch the tiles together in the webview: class ShowMapTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground
