Writing tabs to a file using PowerShell

Question

TLDR: I have two projects(Project A & B) using CMakeLists.txt, both build executables and they work separately. Now, I want to use Project A as a library in Project B, let's call this Project AB. How do I do it?

Current Directory Structures :

Project A

rootA
 |- bin
 |   |-
 |- build
 |   |-
 |- external-includes
 |- CMakeLists.txt with add_subdirectory(libraryA)
 |- libraryA
     |- main.cpp (uses library_A in an example program)
     |- library_A.cpp
     |- library_A.h
     |- Other .h and .cpp files library_A uses
     |- CMakeLists.txt having add_executable (library_A main.cpp library_A.cpp ....)

Project B

rootB
 |- bin
 |   |-
 |- build
 |   |-
 |- external-includes
 |- CMakeLists.txt with add_subdirectory(libraryB)
 |- libraryB
     |- main.cpp
     |- library_B.cpp
     |- library_B.h
     |- Other .h and .cpp files library_B uses
     |- CMakeLists.txt having add_executable (library_B main.cpp library_B.cpp ....)

Project AB

rootAB
 |- bin
 |   |-
 |- build
 |   |-
 |- external-includes
 |- rootA 
 |- CMakeLists.txt with add_subdirectory(libraryB)
 |- libraryB
     |- main.cpp
     |- library_B.cpp
     |- library_B.h
     |- Other .h and .cpp files library_B uses
     |- CMakeLists.txt having add_executable (library_B main.cpp library_B.cpp .....)

What I've tried so far:

I've tried adding include_directories(rootA/libraryA) and add_sudirectory(rootA) to rootAB/CMakeLists.txt and #include <library_A.h> to rootAB/libraryB/main.cpp, then it complains about linking errors(unresolved external symbol). If I add #include <library_A.cpp> , it will complain about other linking errors from library A, which don't occur if I build library_A separately. Probably what I want to do is to build library_A as a (static) library and link it in ProjectAB (preferably using current directory structure and modifications to CMakeLists.txt(s)). How to do so?

Solution 1

You can use `t for a tab character in a double quoted string. You can also simplify the above to:

"$($fields[0])   $($fields[1])   $($fields[2]) $($fields[3])  $($fields[15])  $($fields[17])" | Add-Content $tempInputDir\testoutput.log

Solution 2

To join the nominated fields together with tabs:

[string]::join("`t", (0..3,15,17 | % {$fields[$_]}))

Perhaps you should have the ` add_library` command in the library sub-directories CMakeLists.txt file? Then you can use that library in a target_link_libraries command.

@Someprogrammerdude Found this , will try and update the question

[Chris Magnuson]

That is a beautiful one liner. Just makes me smile.

[Wouter]

while you're at it: [string]::join("`t", (0..3,15,17 | % {$fields[$_]}))

[Zarepheth]

The `t escape sequence is what I was looking for. Note: that is the reversed apostrophe.

[Peter Mortensen]

Reversed apostrophe? It is ASCII 96 (0x60). It goes under the names backtick, backquote, and grave accent.
