[PATCH] cd command defaults to ~

[PATCH] cd command defaults to ~

[Nathaniel Flath]

Hi,

'cd' in bash defaults to ~, whereas in gdb will throw an error.  This
patch has the 'cd' command in gdb use '~' as a default instead of
giving this error.


Thanks,
Nathaniel Flath

FYI I do not find it too much required, 'cd ~' is not such a burden, one may
expect that 'cd' without parameters will do 'pwd' (which it does not) etc.
Therefore I do not approve it on my own unless someone else does.

It would need an update in doc/doc/gdb.texinfo and probably even gdb/NEWS.

Re: [PATCH] cd command defaults to ~

It's certainly not a huge deal - just something that's been annoying
me for a while.  As for other possible behaviours - I think the POSIX
standard for 'cd' with no arguments is to use the HOME directory, if
it is set - http://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html
is what I was looking at, so I don't think there would be too many
people expecting a completely different behaviour . I'd be willing to
update the two documents you mentioned, if this is an acceptable
change.

Thanks,
Nathaniel Flath

You'd be surprised what Windows users expect to see as result of
typing "cd" without an argument ;-)

(Not that I object to the change you propose, though.)

I think it would be fine.
I think mimicking bash is a good enough reason here.

This is not a real ChangeLog, see other entries plus:
	http://www.gnu.org/prep/standards/standards.html#Change-Logs

BTW it is better not to modify the ChangeLog file(s) itself but write is as
a text along the patch, the repository ChangeLog file(s) as constantly
changing.

Your ChangeLog should have been, including the spacing:

gdb/
2012-07-21  Nathaniel Flath  <flat0103@gmail.com>

	* NEWS: New entry for 'cd' default parameters.
	* cli/cli-cmds.c (cd_command): Replace error_no_arg by DIR assignment.

doc/
2012-07-21  Nathaniel Flath  <flat0103@gmail.com>

	* gdb.texinfo (Working Directory): <FIXME>

But the doc patch part does not seem to be right to me (although authoritative
is Eli).  I would probably create a new entry besides 'cd DIRECTORY' and 'pwd'
also 'cd' (without DIRECTORY).  Or one can modify 'cd DIRECTORY'
to be 'cd [DIRECTORY]' instead.

I guess Tom assumes no FSF copyright assignment is needed for this patch, Tom?


Thanks,
Jan

OK, but since not everyone is born knowing what '~' means (think
Windows users), I would suggest a small correction:

  The 'cd' command now defaults to using '~' (the home directory) if
  not given an argument.

>  @kindex cd
>  @cindex change working directory
>  @item cd @var{directory}

As Jan points out, the DIRECTORY part is now optional, which we
express by [...].  So:

  @item cd @r{[}@var{directory}@r{]}

(The @r{} parts are needed to countermand the default @code formatting
of the @item line.)

> -Set the @value{GDBN} working directory to @var{directory}.
> +Set the @value{GDBN} working directory to @var{directory}.  If given no
> +arguments, uses '~'.

"~" is a file name, so please use @file{~} instead of quoting it.

Also, I would replace the last sentence with

  If not given, @var{directory} defaults to @file{~}.

OK with those changes.

Thanks.

The copyright assignment must be done for each project you are
contributing.  Tom said your changes are small and you don't need one
for GDB, so it is OK.  However, if you ever need to get one, please mail
me off-list and I can send you the form.

The patch is not applicable:
patching file NEWS
patch: **** malformed patch at line 34: * GDB now supports x32 ABI.  Visit <http://sites.google.com/site/x32abi/>

Unaware why.  Most probably the issue gets resolved if you attach the patch
(and not inline it).  It would be better to reconfigure your MUA so that the
inserted patch info mail text is not corrupted.

          ^^
Here the indentation should be two spaces left, ignoring '* ' above.

The NEWS entry was against too old tree, adjusted its position (to be post-7.5).


Thanks,
Jan

It has caused:
	 cd
	-Argument required (new working directory).
	-(gdb) PASS: gdb.base/default.exp: cd
	+Working directory /home/jkratoch.
	+(gdb) FAIL: gdb.base/default.exp: cd

One should run a regression testsuite, I forgot you did not.

Checked in.

Sorry - I saw your later email about the regression - do I need to fix
this commit or did you fix/apply it?

Thanks,
