Typedef Documentation

A revision range, specified in one of svn_opt_revision_kind ways.

A revision, specified in one of svn_opt_revision_kind ways.

A revision value, which can be specified as a number or a date.

Note:
This union was formerly an anonymous inline type in svn_opt_revision_t, and was converted to a named type just to make things easier for SWIG.
Since:
New in 1.3.

One element of a subcommand dispatch table.

Since:
New in 1.4.

One element of a subcommand dispatch table.

Deprecated:
Provided for backward compatibility with the 1.3 API.

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.

Enumeration Type Documentation

Various ways of specifying revisions.

Note:
In contexts where local mods are relevant, the `working' kind refers to the uncommitted "working" revision, which may be modified with respect to its base revision. In other contexts, `working' should behave the same as `committed' or `current'.

Function Documentation

svn_error_t* svn_opt_args_to_target_array ( apr_array_header_t **  targets_p,
apr_getopt_t *  os,
const 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().

Deprecated:
Provided for backward compatibility with the 1.1 API.
svn_error_t* svn_opt_args_to_target_array2 ( apr_array_header_t **  targets_p,
apr_getopt_t *  os,
const 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.

Since:
New in 1.2.
Deprecated:
Provided for backward compatibility with the 1.4 API.
svn_error_t* svn_opt_args_to_target_array3 ( apr_array_header_t **  targets_p,
apr_getopt_t *  os,
const 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).

Deprecated:
Provided for backward compatibility with the 1.5 API.

)

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.

Deprecated:

)

Return the entry in table whose name matches cmd_name, or NULL if none.

cmd_name may be an alias.

Since:
New in 1.4.
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.

Deprecated:
Provided for backward compatibility with the 1.3 API.
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.

Since:
New in 1.4.
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 path 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", (unspecified)
  • "foo/@bar@" -> "foo/@bar", (unspecified)
  • "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" -> "@foo/bar", (unspecified)
  • "@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.

Since:
New in 1.1.
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:

  • If arg is "N", set *start_revision to represent N, and leave *end_revision untouched.
  • If arg is "N:M", set *start_revision and *end_revision to represent N and M respectively.

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").

Note:
It is typical, though not required, for *start_revision and *end_revision to be svn_opt_revision_unspecified kind on entry.

Use pool for temporary allocations.

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.

  • If arg is "N", set the start field of the svn_opt_revision_range_t to represent N and the end field to svn_opt_revision_unspecified.

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.

Since:
New in 1.5.
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.

FILE *  stream 
)

Same as svn_opt_print_generic_help2(), but acts on svn_opt_subcommand_desc_t.

Deprecated:
Provided for backward compatibility with the 1.3 API.
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.

###

Todo:
Why is stream a stdio file instead of an svn 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.

const apr_getopt_option_t *  option_table,
const int *  global_options,

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_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:

  • If is_url is set and peg_rev->kind is svn_opt_revision_unspecified, peg_rev->kind defaults to svn_opt_revision_head.
  • If is_url is not set, and peg_rev->kind is svn_opt_revision_unspecified, peg_rev->kind defaults to svn_opt_revision_base.
  • If op_rev->kind is 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.

Get subcommand's usage from table, and print it to stdout.

Obtain option usage from options_table. If not NULL, global_options is a zero-terminated list of global options. Use pool for temporary allocation. subcommand may be a canonical command name or an alias. ###

Todo:
Why does this only print to stdout, whereas svn_opt_print_generic_help() gives us a choice?

When printing the description of an option, if the same option code appears a second time in options_table with a different name, then use that second name as an alias for the first name. This additional behaviour is new in 1.7.

Return TRUE iff subcommand command supports option option_code, else return FALSE.

Same as svn_opt_subcommand_takes_option2(), but acts on svn_opt_subcommand_desc_t.

svn_boolean_t svn_opt_subcommand_takes_option2 ( const svn_opt_subcommand_desc2_t command,

Same as svn_opt_subcommand_takes_option3(), but with NULL for global_options.

Deprecated:

svn_boolean_t svn_opt_subcommand_takes_option3 ( const svn_opt_subcommand_desc2_t command,
int  option_code,
const int *  global_options 
)

Return TRUE iff subcommand command supports option option_code, else return FALSE.

If global_options is non-NULL, it is a zero-terminated array, and all subcommands take the options listed in it.
