[RFA] Make first and last lines of 'command help documentation' consistent.
Commit Message
With this patch, the help docs now respect 2 invariants:
* The first line of a command help is terminated by a '.' character.
* The last character of a command help is not a newline character.
Note that the changes for the last invariant were done by Tom, as part of :
[PATCH] Remove trailing newlines from help text
https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html
but some occurrences have been re-introduced since then.
Some help docs had to be rephrased/restructured to respect the above
invariants.
Before this patch, print_doc_line was printing the first line
of a command help documentation, but stopping at the first '.'
or ',' character.
This was giving inconsistent results :
* The first line of command helps was sometimes '.' terminated,
sometimes not.
* The first line of command helps was not always designed to be
readable/understandable/unambiguous when stopping at the first
'.' or ',' character.
This e.g. created the following inconsistencies/problems:
< catch exception -- Catch Ada exceptions
< catch handlers -- Catch Ada exceptions
< catch syscall -- Catch system calls by their names
< down-silently -- Same as the `down' command
while the new help is:
> catch exception -- Catch Ada exceptions, when raised.
> catch handlers -- Catch Ada exceptions, when handled.
> catch syscall -- Catch system calls by their names, groups and/or numbers.
> down-silently -- Same as the `down' command, but does not print anything.
Also, the command help doc should not be terminated by a newline
character, but this was not respected by all commands.
The cli-option -OPT framework re-introduced some occurences.
The -OPT build help framework was changed to not output newlines at the
end of %OPTIONS% replacement.
This patch changes the help documentations to ensure the 2 invariants
given above.
It implied to slightly rephrase or restructure some help docs.
The test gdb.base/help.exp is modified to verify these invariants
automatically for all commands compiled in GDB.
Based on the above invariants, print_doc_line (called by
'apropos' and 'help' commands to print the first line of a command
help) now outputs the full first line of a command help.
This all results in a lot of small changes in the produced help docs.
There are less code changes than changes in the help docs, as a lot
of docs are produced by some code (e.g. the remote packet usage settings).
If you want, you might look at the new resulting help by doing the following
command in a HEAD GDB and in a GDB with this patch, and then
use emacs M-x ediff-files (or the diff tool you prefer) to review
the changes in the 'full_help.txt', checking a.o. that the
first line of the help of a command is understanble by itself.
(gdb) |apropos -v .| cat > full_help.txt
full_help.txt has a lot of small differences (but less than the
one_line_help.txt below) because:
* excess new-lines at the end of docs have been removed.
* missing . at end of first line have been added.
You can also produce a file with just the first line of help:
(gdb) |apropos .| cat > one_line_help.txt
The 'one_line_help.txt' contains a lot more of artificial differences,
as the HEAD GDB does not output the trailing '.' character.
gdb/ChangeLog
2019-06-16 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* cli/cli-decode.h (print_doc_line): Add for_value_prefix argument.
* cli/cli-decode.c (print_doc_line): Likewise. It now prints
the full first line, except when FOR_VALUE_PREFIX. In this case,
the trailing '.' is not output, and the first character is uppercased.
(print_help_for_command): Update call to print_doc_line.
(print_doc_of_command): Likewise. Output a specific string
when doc string ends with a line feed to allow the testsuite
to detect the broken invariant.
* cli/cli-setshow.c (deprecated_show_value_hack): Likewise.
* cli/cli-option.c (append_indented_doc): Do not append newline.
(build_help_option): Append newline after first appended_indented_doc
only if a second call is done.
(build_help): Append 2 new lines before each option, except the first
one.
* compile/compile.c (_initialize_compile): Add new lines after
%OPTIONS%, when not at the end of the help.
C hange help doc or code
producing the help doc to respect the invariants.
* maint-test-options.c (_initialize_maint_test_options): Likewise.
Also removed the new line after 'Options:', as all other commands
do not put an empty line between 'Options:' and the first option.
* printcmd.c (_initialize_printcmd): Likewise.
* stack.c (_initialize_stack): Likewise.
* interps.c (interpreter_exec_cmd): Fix "Usage:" line that was
incorrectly telling COMMAND is optional.

I think this can't be an assertion, because user commands could hit it,
and that seems too harsh; but could it be a unit test? That might be
better than printing something magic, especially since IIUC the user can
end up seeing this stuff.

I'm not sure we can rely on having grep in the test suite. If you
switch the patch to a self-test, then this is moot; otherwise, is this
used elsewhere? I think a different approach is to write to a log file
and then examine it with Tcl. I believe some other tests do this.

Effectively, the user can end up seeing this, but only if the GDB test
was not run and/or was not fixed.

The testsuite uses various unix commands such as mv/touch/grep/stty/...
But maybe these tests are all failing e.g. on windows ?
In any case, I will see if it is easy to do a selftest instead,
without duplicating too much of e.g. the recursive traversal of the commands,
maybe by adding a 'for_self_test' boolean arg to apropos_command ...
Thanks for the comments,

Or if there is any command written in Python or Guile that has a newline
at the end of its help text. These commands can be supplied any number
of ways.

Could this be a warning at command-registration-time instead? That
way you would see if as soon as the command is registered. And it'd
be hard to introduce a regression with build-in commands since
everyone would start seeing a warning.

Where I was coming from is that this is a pretty minor cosmetic issue;
and while it makes sense for gdb to follow this rule, it isn't worth it
for 3rd party commands. So, we should test gdb itself to avoid problems
here, but ignore problems coming from elsewhere.
I don't feel super strongly about it.

This sentence is incorrect -- there's only one command to execute.
You meant to say that it's the command to execute and its arguments.
As it was before was also correct, IMHO.

"files names directories" reads a bit ood, seems like a plural too many

Maybe you're missing a possessive apostrophe, like:

I think this "or auto-display expressions" part should be removed,
since "delete NUM" does not delete displays -- "delete display" does.
I see no reason for "apropos display" to show "delete", for example.

Can you split these parts of the patch from the validation parts?
I.e., let's get the help fixes out of the way first. The validation
parts can be discussed separately, and it's easier to distinguish
them if they're not mixed up with the rest.

I agree that it's not desirable to include the extra markup in the
help output of 3rd party commands. That seems too harsh since it shows
up on every invocation and is certainly distracting for the user.
I kind of assumed that the markup also catches bad uses of the '.',
which affects proper integration with "apropos". If it's just for
the end line, then it's less of a deal.
My view was that that a warning is much less invasive than changing the
help text, since a warning would show (usually) at gdb startup when some
script is loaded, where users already get some text they need to
scroll over.
We could also make it a gdb_assert in the add_cmd functions,
and then make the python layer strip away any trailing whitespace.

I think this is my preferred solution, btw. Makes it unnecessary to
add any testing infrastructure, and makes python do the right thing
automatically.

The code loops over a set of strings,
and execute each of these strings.
When trying:
(gdb) interpreter-exec console bt bt
#0Â Â 0x00007ffff78fe603 in select () at ../sysdeps/unix/syscall-template.S:84
#1Â Â 0x0000555555554f5e in sleeper_or_burner (v=0x7fffffffdf30) at sleepers.c:86
#2Â Â 0x000055555555549d in main (argc=1, argv=0x7fffffffe0b8) at sleepers.c:194

#2Â Â 0x000055555555549d in main (argc=1, argv=0x7fffffffe0b8) at sleepers.c:194
(gdb)
Now, I have to admit that at least for the console interpreter, unclear where
the syntax for the arguments is described.
Looks like the below works:
(gdb) interpreter-exec console bt\ 1 bt\ 2
#0Â Â 0x00007ffff78fe603 in select () at ../sysdeps/unix/syscall-template.S:84
(More stack frames follow...)
#0Â Â 0x00007ffff78fe603 in select () at ../sysdeps/unix/syscall-template.S:84
#1Â Â 0x0000555555554f5e in sleeper_or_burner (v=0x7fffffffdf30) at sleepers.c:86
(More stack frames follow...)
(gdb)Â
This also works:
(gdb) interpreter-exec console "bt 1" "bt 2"
#0Â Â 0x00007ffff78fe603 in select () at ../sysdeps/unix/syscall-template.S:84
(More stack frames follow...)
#0Â Â 0x00007ffff78fe603 in select () at ../sysdeps/unix/syscall-template.S:84
#1Â Â 0x0000555555554f5e in sleeper_or_burner (v=0x7fffffffdf30) at sleepers.c:86
(More stack frames follow...)
(gdb)Â
So, it looks like really several commands can be given, but I am not sure
if the commands and argument syntax is the same for all interpreters.
Also, when looking at some mi documentation, we again see only one command
mentionned:
The '-interpreter-exec' Command
-------------------------------

     -interpreter-exec INTERPRETER COMMAND
