I'm planning to release a new debugger for D sometime during
end of February. This is a heads up for all those who are
eagerly looking for a good debugger for D.
Here is a sample debug session:
$ ./dbg ./dbg
New session s1 (./dbg) started
New process p1 (program dbg) created
p1.1 SUSPENDED [D main in dbg.d]
78: main(string[] args)
dbg> list 175
Source listing for thread p1.1, program dbg
175: if (srcpath !is null)
176: dv_dbgSrcpath(srcpath);
177: if (sympath !is null)
178: dv_dbgSympath(sympath);
179: auto cmd = new Command(uiType);
180: cmd.rc_exec(GLOBAL_DBGRC_FILE);
181: if (dbgrc is null)
182: {
183: dbgrc = homedir ~ "/" ~ DBGRC_FILE;
184: cmd.rc_exec(dbgrc); // home dir dbgrc
dbg> run -u 179
p1.1 SUSPENDED [D main in dbg.d]
179: auto cmd = new Command(uiType);
dbg> step -o
p1.1 STEPPED [D main in dbg.d]
180: cmd.rc_exec(GLOBAL_DBGRC_FILE);
dbg> help
Run help on the following topics to get additional help.

For a full list of help topics, run "help toc".
dbg> help create
SYNOPSIS:
create [-f <follow>] [-l] [-s <srcpath>] [-S <sympath>]
[<shell_cmd_string>]
DESCRIPTION:
Create a new debugging session for <shell_cmd_string>. The
existing debug
sessions are not affected by this command. One could
simultaneously
have multiple debug sessions. If <shell_cmd_string> is not
specified, the
<shell_cmd_string> from previous create command is used and
the previous
create session is destroyed. After the session is created,
this command
runs all the processes till their 'start' function.
OPTIONS:
-f follow 'prog', 'proc', 'thread' or 'all' or 'none'
-l load only; do not run new program / thread till its
'start' function
-s paths for source files
-S paths for debug symbol files
NOTES:
It is not possible to redirect or pipe the output of create
command.
EXAMPLES:
create test_prog1 arg1 arg2 2>/tmp/prog1.err | test_prog2
# creates a new debug session for test_prog1 and
test_prog2
create MANPAGER=more man 1p man
create xterm -e ./cmd
