问题 This is a duplicate of Generate scaladoc for root package, however the Answer does not state where sbt doc looks for the rootdoc.txt . I added scalacOptions in doc ++= Seq("-doc-root-content", "rootdoc.txt") to my build.sbt , but sbt doc does not seem to scan it. I tried to put it next to the build.sbt , in src , src/main , src/main/scala I am using sbt 0.12.3 回答1: It seems that your arguments are not given to scaladoc at all. I cannot figure out why the command line arguments are not passed

问题 I use Kodingen.com to test python scripts. I would like to install new python packages on Kodingen. I know I can use the 1-Click installation of the App-Store to install new packages from ohloh.net. When I install a package, it create a new directory in httpdocs folder. And then? How to setup the python package to use import in my scripts? Is it possible for a user to do it? I'm looking for the complete procedure. As example, we can use PIL (Python Imaging Library). How to install it? For

问题 Here's my directory setup: mydir ├── script1.py └── shared ├── otherstuff ├── script2.py └── pkg ├── box.py └── __init__.py script2.py starts with import pkg and it works great. When I include the same line in script1.py , I get: Traceback (most recent call last): File "script1.py", line 1, in <module> import pkg Is there any good way to get syntax that simple to work in script1.py ? I have been reading about PYTHONPATH and sys.path for the past hour, but I'm trying to make some basic

问题 The short story : In the directory ...\octave-4.2.1\share\octave\packages there were initially 45 package subdirectories (with .m and other files), for instance financial-0.5.0 . But I could not find a way to use them . In more detail : I have unzipped the portable (.zip) version of Octave 4.2.1 64 bit for Windows, at 8:00am (useful info for later), into C:\Users\user1\DOCUME~1\apps\OCTAVE~1.1 (originally C:\Users\user1\Documents\apps\octave-4.2.1 ). I have then installed symbolic-2.6.0 (at 8

问题 I have two packages - x and y. x contains the Student class and the Grade enum. y contains the Klass class. Why is the type Student.Grade.C not recognized in the Klass class in package y? Do I need to define it in its own file and make it public? package x; enum Grade { A, B, C, D, F, INCOMPLETE }; public class Student { // blah, blah, member variables, getters, setters, constructors } package y; public class Klass { // This enum type is not recognized in this package public static final

问题 Consider a package hierarchy folder1/hi . folder1 contains A.java and hi contains B.java. B.java: package aa.pkg; public class B { } A.java: package hi.aa.pkg; public class A {B b; } Now B.java compiles successfully, but A.java does not. I am using these commands in cmd (if the current directory is folder1 ): javac -d hi hi/B.java javac -cp hi -d . A.java It says class B not found. What is the correct cmd commands to compile A.java or what should the code look like for this to work? 回答1: You

问题 I need to compare a query bit sequence with a database of up to a million bit sequences. All bit sequences are 100 bits long. I need the lookup to be as fast as possible. Are there any packages out there for fast determination of the similarity between two bit sequences? --Edit-- The bit sequences are position sensitive. I have seen a possible algorithm on Bit Twiddling Hacks but if there is a ready made package that would be better. 回答1: If the database is rather static, you may want to

问题 Why is it that in Java, a superclass' protected members are inaccessible by an indirect subclass in a different package? I know that a direct subclass in a different package can access the superclass' protected members. I thought any subclass can access its inherited protected members. EDIT Sorry novice mistake, subclasses can access an indirect superclasses' protected members. 回答1: Perhaps you're a little confused. Here's my quick demo and shows an indirect subclass accessing a protected

问题 I am running CentOS 5.2 and using yum to manage packages. I have had little luck installing php-posix but know with almost 100% certitude that it is a real and available package...somewhere. Has anyone had luck installing it? FWIW, I am using the following: sudo yum install -y php-posix Update: I've realized that this may be an issue with my host (Slicehost) as I do in fact have cli, posix, and pcntl enabled for my PHP version (5.2.9) 回答1: You can try and see if it's in the testing repository
