https://dlang.org/install.html#activate

I ran the two curl liners for grabbing DMD and LDC newest.

So now I have ~/dlang/ldc-1.32.2 and ~/dlang/dmd-2.104.0

How am I supposed to have both "activated"? Why does LDC have to override DMD, and DMD have to override LDC in the PATH?

I have both installed on another system without using this script and they run fine side-by-side. I can call dmd, or ldc, without any special "activate" calls. But this script seems to be the easiest/fastest way to download DMD and LDC.

I normally have separate scripts for dmd and ldc. (godmd, and goldc) But it seems I'll have to hardcode calls to the right activate script before my normal script code.

#godmd
~/dlang/dmd-2.104.0/activate
dmd -I.......

But the activate scripts may have different version numbers in path!

~/dlang/dmd-2.104.0/activate

will one day become

~/dlang/dmd-2.105.0/activate

and so on.

Who said it has to? Run the activation scripts the other way around. It just prepends them to the binary search path.

Don't put the activate command in your script like that in the first place. You can run it in your shell's .profile, or just append the directories from ~/dlang/install.sh get-path to the .profile yourself:

#use a specific version you already have:
PATH="$(dirname $(~/dlang/install.sh get-path dmd-2.104.0)):$PATH"
#OR always install the latest version:
PATH="$(dirname $(~/dlang/install.sh get-path dmd --install)):$PATH"

Remember, this is prepending (just like activate), which means if you do this with multiple compilers then the LAST one will take precedence over all the others.
