Some instructions are wrong

[sorawee]

Running non-module

start Racket with the -l option before the arguments to load your program: racket -l errortrace ...

I tried racket -l errortrace -f my-prog.rkts where my-prog.rkts is simply a file with content 1. However, it results in:

#%top-interaction: unbound identifier;
 also, no #%app syntax transformer is bound
  at: #%top-interaction
  in: (#%top-interaction . 1)

Note that running racket -f my-prog.rkts works correctly. Also note that (require errortrace) works correctly.

Compiling collections

I really can't get raco setup --mode errortrace --pkgs <pkg-name> to work, even after deleting compiled directory in <pkg-name>.

This is really a Racket command-line argument corner case. The following instruction will work:

$ racket -l racket/init -l errortrace -f my-progs.rktl 

Here the tricky point is that when Racket is given a single -f instruction, it will first load <init-lib>, enabling top-level interactions. But when the -l errortrace appears before the -f instruction, <init-lib> is no longer automatically loaded into the namespace.

$ racket -h
...
Default options:
 If only configuration options are provided, -i is added
 If only configuration options are before the first argument, -u is added
 If -t/-l/-p/-u appears before the first -i/-e/-f/-r, -n is added
 <init-lib> defaults to racket/init
Switch syntax:
 Multiple single-letter switches can be collapsed, with arguments placed
   after the collapsed switches; the first collapsed switch cannot be --
 Example: `-ifve file expr' is the same as `-i -f file -v -e expr'
Start-up sequence:
 1. Set `current-library-collection-paths'
 2. Require `(lib "<init-lib>")' [when -i/-e/-f/-r, unless -n]
 3. Evaluate/load expressions/files in order, until first error

a bit late to the party,

@sorawee, you need -j 1. see #25

This issue is completed, right?

Yep
