Zusammenfassung

0000049: Bug or Feature in Bolt? Error if computed string in "LOG s LEVEL..."

Beschreibung

Hello Xavier,

I want to use your bolt-library to have access to
log4ocaml-functionality.

In my code I use as an example this line:

LOG (Printf.sprintf "walker: processing sdnumber: %s\n" s) LEVEL INFO;

But the compiler means that would be wrong:

File "main_layout.ml", line 37, characters 14-15:
Parse error: [expr level ;] expected after "in" (in [expr])
Preprocessor error

I compiled this with "ocamlopt.opt -pp "camlp4o $(BOLT) -level INFO"

If I replace the line with:

LOG "walker" LEVEL INFO;

the compiler is happy and the binary will be created (and works as
expected).

If I am wrong, could you explain me this behaviour, please?

Thanks in advance,

Bye Andreas

(0000198) xclerc (Administrator) 2009-12-17 20:13	This is indeed how version 1.0-beta worked: the argument following the "LOG" keyword had to be a string literal (and not any expression with type string). However, I stumbled upon the very same problem you experienced. As a consequence, the syntax has been extended to allow the following construct: LOG <format-string> <arguments> <attributes> LEVEL <lvl> In your case, this means: LOG "walker: processing sdnumber: %s\n" s LEVEL INFO
