Jon Degenhardt <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |m --- Comment #1 from Jon Degenhardt <[email protected]> --- I tried to replicate this with the program below. It failed in the described way for the boolean option, but not for the others. If the original author found other cases it would be worth listing them. ==== getopt_repeated_args.d ==== void main(string[] args) { import std.getopt; import std.stdio; int counter; bool flag; int num; void dryrun0() { writeln("dryrun0"); } void dryrun1(string opt) { writefln("dryrun1(%s)", opt); } void dryrun2(string opt, string val) { writefln("dryrun2(%s, %s)", opt, val); } auto r = getopt( args, "c|counter+", "Counter", &counter, "f|flag", "flag", &flag, "n|num", "number", &num, "x|dryrun0", "zero args", &dryrun0, "y|dryrun1", "option is arg", &dryrun1, "z|dryrun2", "option and val are args", &dryrun2, ); if (r.helpWanted) defaultGetoptPrinter("Options:", r.options); else writefln("counter: %d; flag: %s; num: %d", counter, flag, num); return; } ================ ## All work with repeated invocation except the boolean case. $ ./getopt_repeated_args -c -n 5 -c -n 7 counter: 2; flag: false; num: 7 $ ./getopt_repeated_args --dryrun0 --dryrun0 dryrun0 dryrun0 counter: 0; flag: false; num: 0 $ ./getopt_repeated_args -x -x -y -y -z A -z B dryrun0 dryrun0 dryrun1(y|dryrun1) dryrun1(y|dryrun1) dryrun2(z|dryrun2, A) dryrun2(z|dryrun2, B) counter: 0; flag: false; num: 0 ## Single invocation of the boolean option works $ ./getopt_repeated_args -f counter: 0; flag: true; num: 0 $ ./getopt_repeated_args --flag=true counter: 0; flag: true; num: 0 ## Repeated invocation of the boolean option fails $ ./getopt_repeated_args -f -f std.getopt.GetOptException@/Library/D/dmd/src/phobos/std/getopt.d(790): Unrecognized option -f $ ./getopt_repeated_args --flag=true --flag=false std.getopt.GetOptException@/Library/D/dmd/src/phobos/std/getopt.d(790): Unrecognized option --flag=false --
