Enum help string formatting #554
Description
I used the example code to be able to enter a parameter as a number or as enum string.
std::map<std::string, FirmwareUpdateBase::FirmwareUpdateFlags> flagsMap{
{ "normal", normal },
{ "allow_downgrade", allow_downgrade },
{ "force_update", force_update},
{ "no_check", no_check},
{ "normal_check_only", normal_check_only},
{ "allow_downgrade_check_only", allow_downgrade_check_only},
{ "force_update_check_only", force_update_check_only }
};
app.add_option("--flags", flags_, "FW Update Flags")->default_val(normal)->transform(CLI::CheckedTransformer(flagsMap));
However the formatting of the help string is not very clear. All values are displayed in one raw, which is than broken by the width console of the window and is hard to read.
Options:
-h,--help Print this help message and exit
--flags ENUM:value in {allow_downgrade->1,allow_downgrade_check_only->5,force_update->2,force_update_check_only->6,no_
check->3,normal->0,normal_check_only->4} OR {1,5,2,6,3,0,4}=0
FW Update Flags
Would it be possible to display enum options in separate lines? Something like below? This would make the help output much more useful.
Options:
-h,--help Print this help message and exit
--flags ENUM:value in {
allow_downgrade->1,
allow_downgrade_check_only->5,
force_update->2,
force_update_check_only->6,
no_check->3,
normal->0,
normal_check_only->4
} OR {1,5,2,6,3,0,4}=0
FW Update Flags
