ways.
typedef struct svn_opt_revision_t svn_opt_revision_t |
A revision, specified in one of svn_opt_revision_kind
ways.

Like svn_opt_subcommand_desc2_t but lacking the desc_overrides
member.
typedef svn_error_t*( svn_opt_subcommand_t)(apr_getopt_t *os, void *baton, apr_pool_t *pool) |
All subcommand procedures in Subversion conform to this prototype.
os is the apr option state after getopt processing has been run; in other words, it still contains the non-option arguments following the subcommand. See os->argv and os->ind.
baton is anything you need it to be.
pool is used for allocating errors, and for any other allocation unless the instance is explicitly documented to allocate from a pool in baton.
Various ways of specifying revisions.
svn_error_t* svn_opt_args_to_target_array | ( | apr_array_header_t ** | targets_p, |
apr_getopt_t * | os, | ||
apr_array_header_t * | known_targets, | ||
svn_opt_revision_t * | start_revision, | ||
svn_opt_revision_t * | end_revision, | ||
svn_boolean_t | extract_revisions, | ||
apr_pool_t * | pool | ||
) |
The same as svn_opt_args_to_target_array2() except that, in addition, if extract_revisions is set, then look for trailing "@rev" syntax on the first two paths.
If the first target in *targets_p ends in "@rev", replace it with a canonicalized version of the part before "@rev" and replace *start_revision with the value of "rev". If the second target in *targets_p ends in "@rev", replace it with a canonicalized version of the part before "@rev" and replace *end_revision with the value of "rev". Ignore revision specifiers on any further paths. "rev" can be any form of single revision specifier, as accepted by svn_opt_parse_revision().
svn_error_t* svn_opt_args_to_target_array2 | ( | apr_array_header_t ** | targets_p, |
apr_getopt_t * | os, | ||
apr_array_header_t * | known_targets, | ||
apr_pool_t * | pool | ||
) |
This is the same as svn_opt_args_to_target_array3() except that it silently ignores paths that have the same name as a working copy administrative directory.
svn_error_t* svn_opt_args_to_target_array3 | ( | apr_array_header_t ** | targets_p, |
apr_getopt_t * | os, | ||
apr_array_header_t * | known_targets, | ||
apr_pool_t * | pool | ||
) |
Pull remaining target arguments from os into *targets_p, converting them to UTF-8, followed by targets from known_targets (which might come from, for example, the "--targets" command line option), which are already in UTF-8.
On each URL target, do some IRI-to-URI encoding and some auto-escaping. On each local path, canonicalize case and path separators.
Allocate *targets_p and its elements in pool.
If a path has the same name as a Subversion working copy administrative directory, return SVN_ERR_RESERVED_FILENAME_SPECIFIED; if multiple reserved paths are encountered, return a chain of errors, all of which are SVN_ERR_RESERVED_FILENAME_SPECIFIED. Do not return this type of error in a chain with any other type of error, and if this is the only type of error encountered, complete the operation before returning the error(s).
void svn_opt_format_option | ( | const char ** | string, |
const apr_getopt_option_t * | opt, | ||
svn_boolean_t | doc, | ||
apr_pool_t * | pool | ||
) |
Print an option opt nicely into a string allocated in pool.
If doc is set, include the generic documentation string of opt, localized to the current locale if a translation is available.
const svn_opt_subcommand_desc_t* svn_opt_get_canonical_subcommand | ( | const svn_opt_subcommand_desc_t * | table, |
const char * | cmd_name | ||
) |
Return the entry in table whose name matches cmd_name, or NULL
if none.
cmd_name may be an alias.
Same as svn_opt_get_canonical_subcommand2(), but acts on svn_opt_subcommand_desc_t.
const svn_opt_subcommand_desc2_t* svn_opt_get_canonical_subcommand2 | ( | const svn_opt_subcommand_desc2_t * | table, |
const char * | cmd_name | ||
) |
Return the entry in table whose name matches cmd_name, or NULL
if none.
cmd_name may be an alias.
const apr_getopt_option_t* svn_opt_get_option_from_code | ( | int | code, |
const apr_getopt_option_t * | option_table | ||
) |
Return the first entry from option_table whose option code is code, or NULL
if no match.
option_table must end with an element whose every field is zero.
const apr_getopt_option_t* svn_opt_get_option_from_code2 | ( | int | code, |
const apr_getopt_option_t * | option_table, | ||
const svn_opt_subcommand_desc2_t * | command, | ||
apr_pool_t * | pool | ||
) |
Return pointer to an apr_getopt_option_t
for the option whose option code is code, or NULL
if no match.
option_table must end with an element whose every field is zero. If command
is non-NULL, then return the subcommand-specific option description instead of the generic one, if a specific description is defined.
The returned value may be statically allocated, or allocated in pool.
svn_error_t* svn_opt_parse_all_args | ( | apr_array_header_t ** | args_p, |
apr_getopt_t * | os, | ||
apr_pool_t * | pool | ||
) |
Parse all remaining arguments from os->argv, return them as const char *
in *args_p, without doing any UTF-8 conversion.
Allocate *args_p and its values in pool.
svn_error_t* svn_opt_parse_num_args | ( | apr_array_header_t ** | args_p, |
apr_getopt_t * | os, | ||
int | num_args, | ||
apr_pool_t * | pool | ||
) |
Parse num_args non-target arguments from the list of arguments in os->argv, return them as const char *
in *args_p, without doing any UTF-8 conversion.
Allocate *args_p and its values in pool.
svn_error_t* svn_opt_parse_path | ( | svn_opt_revision_t * | rev, |
const char ** | truepath, | ||
const char * | path, | ||
apr_pool_t * | pool | ||
) |
Parse a working-copy or URL in path, extracting any trailing revision specifier of the form "@rev" from the last component of the path.
Some examples would be:
"foo/bar" -> "foo/bar", (unspecified) "foo/bar@13" -> "foo/bar", (number, 13) "foo/bar@HEAD" -> "foo/bar", (head) "foo/bar@{1999-12-31}" -> "foo/bar", (date, 1999-12-31) "http://a/b@27" -> "http://a/b", (number, 27) "http://a/b@COMMITTED" -> "http://a/b", (committed) [*] "http://a/b@{1999-12-31} -> "http://a/b", (date, 1999-12-31) "http://a/b@%7B1999-12-31%7D -> "http://a/b", (date, 1999-12-31) "foo/bar@1:2" -> error "foo/bar@baz" -> error "foo/bar@" -> "foo/bar", (base) "foo/@bar@" -> "foo/@bar", (base) "foo/bar/@13" -> "foo/bar/", (number, 13) "foo/bar@@13" -> "foo/bar@", (number, 13) "foo/@bar@HEAD" -> "foo/@bar", (head) "foo@/bar" -> "foo@/bar", (unspecified) "foo@HEAD/bar" -> "foo@HEAD/bar", (unspecified) "@foo/bar" -> error "@foo/bar@" -> "@foo/bar", (unspecified)
[*] Syntactically valid but probably not semantically useful.
If a trailing revision specifier is found, parse it into *rev and put the rest of the path into *truepath, allocating from pool; or return an SVN_ERR_CL_ARG_PARSING_ERROR
(with the effect on *truepath undefined) if the revision specifier is invalid. If no trailing revision specifier is found, set *truepath to path and rev->kind to svn_opt_revision_unspecified
.
This function does not require that path be in canonical form. No canonicalization is done and *truepath will only be in canonical form if path is in canonical form.
int svn_opt_parse_revision | ( | svn_opt_revision_t * | start_revision, |
svn_opt_revision_t * | end_revision, | ||
const char * | arg, | ||
apr_pool_t * | pool | ||
) |
Set *start_revision and/or *end_revision according to arg, where arg is "N" or "N:M", like so:
N and/or M may be one of the special revision descriptors recognized by revision_from_word(), or a date in curly braces.
If arg is invalid, return -1; else return 0. It is invalid to omit a revision (as in, ":", "N:" or ":M").

int svn_opt_parse_revision_to_range | ( | apr_array_header_t * | opt_ranges, |
const char * | arg, | ||
apr_pool_t * | pool | ||
) |
Parse arg, where arg is "N" or "N:M", into a svn_opt_revision_range_t
and push that onto opt_ranges.
start

to represent N and the end
field to svn_opt_revision_unspecified
.start

to represent N and the end
field to represent M.If arg is invalid, return -1; else return 0. It is invalid to omit a revision (as in, ":", "N:" or ":M").
Use pool to allocate svn_opt_revision_range_t
pushed to the array.
svn_error_t* svn_opt_parse_revprop | ( | apr_hash_t ** | revprops, |
const char * | revprop_spec, | ||
apr_pool_t * | pool | ||
) |
Parse revprop key/value pair from revprop_spec (name[=value]) into revprops, making copies of both with pool.
If revprops is NULL
, allocate a new apr_hash_t in it. revprops maps const char * revprop names to svn_string_t * revprop values for use with svn_repos_get_commit_editor5 and other get_commit_editor APIs.
void svn_opt_print_generic_help | ( | const char * | header, |
const svn_opt_subcommand_desc_t * | cmd_table, | ||
const apr_getopt_option_t * | opt_table, | ||
const char * | footer, | ||
apr_pool_t * | pool, | ||
FILE * | stream | ||
) |
Same as svn_opt_print_generic_help2(), but acts on svn_opt_subcommand_desc_t.
void svn_opt_print_generic_help2 | ( | const char * | header, |
const svn_opt_subcommand_desc2_t * | cmd_table, | ||
const apr_getopt_option_t * | opt_table, | ||
const char * | footer, | ||
apr_pool_t * | pool, | ||
FILE * | stream | ||
) |
Print a generic (not command-specific) usage message to stream.
###
If header is non-NULL, print header followed by a newline. Then loop over cmd_table printing the usage for each command (getting option usages from opt_table). Then if footer is non-NULL, print footer followed by a newline.
Use pool for temporary allocation.
svn_error_t* svn_opt_print_help | ( | apr_getopt_t * | os, |

Same as svn_opt_print_help3(), but with global_options always NULL
.
svn_error_t* svn_opt_print_help3 | ( | apr_getopt_t * | os, |
const char * | pgm_name, | ||

const apr_getopt_option_t * | option_table, | ||
const int * | global_options, | ||
const char * | footer, | ||
apr_pool_t * | pool | ||
) |
Central dispatcher function for various kinds of help message.
Prints one of: * subcommand-specific help (svn_opt_subcommand_help) * generic help (svn_opt_print_generic_help) * version info * simple usage complaint: "Type '@a pgm_name help' for usage."
If os is not NULL
and it contains arguments, then try printing help for them as though they are subcommands, using cmd_table and option_table for option information. If not NULL
, global_options is a zero-terminated array of options taken by all subcommands.
Else, if print_version is TRUE, then print version info, in brief form if quiet is also TRUE; if quiet is FALSE, then if version_footer is non-NULL, print it following the version information.
Else, if os is not NULL
and does not contain arguments, print generic help, via svn_opt_print_generic_help2() with the header, cmd_table, option_table, and footer arguments.
Else, when os is NULL
, print the simple usage complaint.
Use pool for temporary allocations.
Notes: The reason this function handles both version printing and general usage help is that a confused user might put both the --version flag *and* subcommand arguments on a help command line. The logic for handling such a situation should be in one place.
void svn_opt_push_implicit_dot_target | ( | apr_array_header_t * | targets, |
apr_pool_t * | pool | ||
) |
If no targets exist in *targets, add `.
' as the lone target.
(Some commands take an implicit "." string argument when invoked with no arguments. Those commands make use of this function to add "." to the target array if the user passes no args.)
svn_error_t* svn_opt_resolve_revisions | ( | svn_opt_revision_t * | peg_rev, |
svn_opt_revision_t * | op_rev, | ||
svn_boolean_t | is_url, | ||
svn_boolean_t | notice_local_mods, | ||
apr_pool_t * | pool | ||
) |
Resolve peg revisions and operational revisions in the following way:
svn_opt_revision_unspecified
, peg_rev->kind defaults to svn_opt_revision_head
.svn_opt_revision_unspecified
, peg_rev->kind defaults to svn_opt_revision_base
.svn_opt_revision_unspecified
, op_rev defaults to peg_rev.Both peg_rev and op_rev may be modified as a result of this function. is_url should be set if the path the revisions refer to is a url, and unset otherwise.
If notice_local_mods is set, svn_opt_revision_working
is used, instead of svn_opt_revision_base
.
Use pool for allocations.
void svn_opt_subcommand_help | ( | const char * | subcommand, |
const svn_opt_subcommand_desc_t * | table, | ||
const apr_getopt_option_t * | options_table, | ||
apr_pool_t * | pool | ||
) |
Same as svn_opt_subcommand_help2(), but acts on svn_opt_subcommand_desc_t.
void svn_opt_subcommand_help2 | ( | const char * | subcommand, |
const svn_opt_subcommand_desc2_t * | table, | ||
const apr_getopt_option_t * | options_table, | ||

) |
Same as svn_opt_subcommand_help3(), but with global_options always NULL.
void svn_opt_subcommand_help3 | ( | const char * | subcommand, |
const svn_opt_subcommand_desc2_t * | table, | ||
const apr_getopt_option_t * | options_table, | ||
const int * | global_options, | ||
apr_pool_t * | pool | ||
) |
Get subcommand's usage from table, and print it to stdout
