SUV Examples
depends on libuv version 1.8.0-r1, install it according to the repo documentation
Building the Project with SwiftPM:
using toolchain Swift 2.2 Snapshot - December 22, 2015 or later
> swift buildusing toolchain earlier than Swift 2.2 Snapshot - December 22, 2015
When using aversion ealier than the snapshot on December 22,2015 the SwiftPM will act a little funky when linking executables from a dependency. The dependency with the issue in this project is Swiftest. There is a workaround for this linking issues.
workaround:
-
Attempt to build the project.
> swift build -
You should get this output:
Cloning Packages/SUV Cloning Packages/libUV Cloning Packages/Swiftest Cloning Packages/OS Compiling Swift Module 'OS' (1 sources) Linking Library: .build/debug/OS.a Compiling Swift Module 'Swiftest' (27 sources) Linking Library: .build/debug/Swiftest.a Compiling Swift Module 'Example' (8 sources) Linking Executable: .build/debug/Example /usr/bin/ld: cannot find /path/to/SUVExamples/.build/debug/SUV.a: No such file or directory
-
That's not a very descriptive output, and doesn't relay anything about the linking issues, but I promise it is a linking problem (I think). To resolve it, delete the Example directory in the Swiftest Package that is cloned.
> rm -r Packages/Swiftest-0.1.4/src/Example -
Now if you build the projects again:
> swift build -
You should get the final bit of output:
Compiling Swift Module 'SUV' (86 sources) Linking Library: .build/debug/SUV.a Compiling Swift Module 'Spec' (23 sources) Linking Executable: .build/debug/Spec Compiling Swift Module 'Cat' (1 sources) Compiling Swift Module 'EchoServer' (1 sources) Linking Executable: .build/debug/Cat Linking Executable: .build/debug/EchoServer
Examples:
Echo Server
Spins up a server that echos the requests made on http://localhost:8000.
-
Start the server
> ./.build/debug/EchoServer -
Make requests from another terminal
> curl localhost:8000 GET / HTTP/1.1 User-Agent: curl/7.35.0 Host: localhost:8000 Accept: */*
CAT
Reads the provided file and prints it to standard out
-
execute the command
> ./.build/debug/Cat ./Resources/cat.txt ,';, ,';, ,' , :; ; ,,.; | |:; :; ; ;:|.| | |::; ';,,,,,,,,,' ;:|.| ,,,;;;;;;;;,,, ; |'' ___ ___ ';.;,,'' ''';,,, ',: / \ / \ .;.

TEE
Read from standard input and logs to a file and standard output
-
execute the command
> ./.build/debug/Cat ./Resources/cat.txt | ./.build/debug/Tee ./Resources/tee.txt | grep "/" ',: / \ / \ .;.
