content format when missing required option

[kunlk]

Hi,

This issue should be a question other than bug. Thank you for your help in advance !

The question is when one required option was missing, the usage out put doesn't display the command in one line.

For example as below, I expect that "synctl export -baselineselector= -loadrule= -snapath=" could be displayed in one line but it's wrapped.

c:\shared\vvctl>synctl.bat export -baselineselector wp_zxm_proj1_Int_0.12.0 -snapath C:\myview1
Missing required option '-loadrule='
export data
Usage: synctl export -baselineselector= -loadrule=
-snapath=
-baselineselector=
baseline selector name
-loadrule= load rule
-snapath=
snapshot path

In case the description doesn't clear, paste a screenshot

Thanks, the screenshot helped!

By default the usage help width is 80 characters, but this is configurable:

see https://picocli.info/#_usage_width

Thanks @remkop, it works great. For the options lists below the usage line, is there a way to set the width too ? For example, the option lines for -baselineselector and -snapath break.

[remkop]

Yes, see https://picocli.info/#_long_option_column_width

HI @remkop , I am sorry, but I did not find the method setLongOptionsMaxWidth in CommandLine. I tried to set spec.usageMessage().longOptionsMaxWidth(120); but it did not help.

[remkop]

Looks like I got the name of the CommandLine setter wrong in the documentation.
It should be setUsageHelpLongOptionsMaxWidth.

It needs to be set before the help is shown.

yes, it works perfect, thank you !

I fixed the user manual.
Thanks for raising this!
