Here is a patch to implement processing of arguments in
the subcommand instead of doing it all in main. The
current approach of processing all the subcommand
arguments in main() works, but it is a bit hard
to get your brain around and I an not sure it will
be flexible enough to deal with special cases or
new subcommands that may be added in the future.
Much of this was covered in earlier discussion on
the list so I will not try to rehash it here.
High level changes:
1. Removed num_args field from svn_cl__cmd_desc_t struct.
2. Changed svn_cl__cmd_proc_t signature to:
(apr_getopt_t *, svn_cl__opt_state_t *, apr_pool_t *)
3. Processing or arguments is done in the subcommand.
4. Change svn_cl__help so that it will print
the main program usage if NULL is passed in the
first argument.
5. Subcommand help text is printed if the user passes
an incorrect number of arguments.
6. Add a new error type SVN_ERR_ALREADY_PRINTED. When
svn_handle_error() is called on this type of error
it will print nothing and return.
7. Add "di" shortcut for diff subcommand to match
the CVS implementation.
Detailed changes:
2001-03-16 Mo DeJong <mdejong@redhat.com>
* subversion/client/TODO: Fix number
of arguments listing for the delete,
propget, and propset commands. Fix
minor format issues, add newline at
EOF to avoid diff warning.
* subversion/client/add-cmd.c (svn_cl__add):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
Print subcommand usage if no targets are passed
in on the command line.
* subversion/client/checkout-cmd.c (svn_cl__checkout):
Account for change in svn_cl__cmd_proc_t signature.
Extract args array in the subcommand.
Print subcommand usage if no URLs are passed
in on the command line.
* subversion/client/cl.h (svn_cl__cmd_proc_t,
svn_cl__cmd_desc_t, svn_cl__push_svn_string,
svn_cl__args_to_target_array, svn_cl__parse_num_args,
svn_cl__parse_all_args, svn_cl__subcommand_help):
Change svn_cl__cmd_proc_t signature so that
it accpets a apr_getopt_t* in the first argument
and a svn_cl__opt_state_t* in the second argument.
Remove num_args field from svn_cl__cmd_desc_t.
Add function prototypes for methods defined in
main.c.
* subversion/client/commit-cmd.c (svn_cl__commit):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
* subversion/client/delete-cmd.c (svn_cl__delete):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
Print subcommand usage if no targets are passed
in on the command line.
* subversion/client/diff-cmd.c (svn_cl__diff):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
* subversion/client/help-cmd.c (svn_cl__help,
svn_cl__subcommand_help):
Account for change in svn_cl__cmd_proc_t signature.
Print main help text if the first argument to
svn_cl__help is NULL.
Extract target array in the subcommand.
Add new +svn_cl__subcommand_help helper method,
use it in svn_cl__help.
* subversion/client/main.c (svn_cl__cmd_table,
svn_cl__push_svn_string, svn_cl__parse_num_args,
svn_cl__parse_all_args, svn_cl__args_to_target_array):
Remove svn_cl__cmd_desc_t num_args initializer.
Add "di" shortcut for diff to match CVS shortcut.
Add argument processing helper methods, remove
arguments and targets processing from main().
Remove targets array from main(), it is no
longer passed to a subcommand function.
Call svn_cl__help with NULL in first two arguments,
to print main help text. Fix exit status so that
when an error is encountered, svn will not terminate
with an exit status of 0.
* subversion/client/propget-cmd.c (svn_cl__propget):
Account for change in svn_cl__cmd_proc_t signature.
Use propname and propval variables to match usage.
Extract target array in the subcommand.
* subversion/client/proplist-cmd.c (svn_cl__proplist):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
* subversion/client/propset-cmd.c (svn_cl__propset):
Account for change in svn_cl__cmd_proc_t signature.
Use propname and propval variables to match usage.
Extract args and targets arrays in the subcommand.
Add implicit . if not targets are passed in.
* subversion/client/status-cmd.c (svn_cl__status):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
* subversion/client/update-cmd.c (svn_cl__update):
Account for change in svn_cl__cmd_proc_t signature.
Extract target array in the subcommand.
