Due to some very old mistakes too many of Delve's flags are declared as persistent on cobra's root command. For example the headless flag is a global flag but does not apply to connect, dap or trace; the backend flag does not apply to replay, core and dap; etc. Almost all global flags should have been declared as local flags on individual subcommands. Unfortunately we can not change this without breaking backwards compatibility, for example: dlv --headless debug would not parse if headless was a flag of debug instead of a global flag. Instead we alter usage function and the markdown generation script to strategically hide the flags that don't apply. Fixes #2361

## dlv trace
|
|
|
|
Compile and begin tracing program.
|
|
|
|
### Synopsis
|
|
|
|
Trace program execution.
|
|
|
|
The trace sub command will set a tracepoint on every function matching the
|
|
provided regular expression and output information when tracepoint is hit. This
|
|
is useful if you do not want to begin an entire debug session, but merely want
|
|
to know what functions your process is executing.
|
|
|
|
The output of the trace sub command is printed to stderr, so if you would like to
|
|
only see the output of the trace operations you can redirect stdout.
|
|
|
|
```
|
|
dlv trace [package] regexp [flags]
