Me too. It would be similar to the D Programming Language's facility...
debug
{
... statements ...
}
Some points to consider:
If we use some 'block' syntax, the block needs to be able to span routines as
well as statements, in order to comment out routines just used for debugging.
Eg.
debug
procedure Logger(sequence text)
-- write text to logging file.
end procedure
end debug
or even ...
debug
include stddebug.e as dbg
dbg:init("My App", "/var/debug.log", "append")
end debug
If we use the line prefix style of syntax, then I suggest a double dot, which
is analogous with the double dash for comments. It also visually stands out
more.
.. include stddebug.e as dbg
.. dbg:init("My App", "/var/debug.log", "append")
Also, some way of turning it off/on from the command line instead of having
to edit source code, should be considered.
e.g.
exu myapp.e --eu:debug=on
Finally, to borrow from D language, we could support debug variations.
debug(stage1)
dbg:log("Beginning Stage 1")
vLimit = 1
end debug
debug(stage2)
dbg:log("Beginning Stage 2")
vLimit = 25
end debug
and invoked by ...
ex myapp.e --eu:debug=stage1
