class Rugged::Config
Public Class Methods
Open the default global config file as a new Rugged::Config
object. An exception will be raised if the global config file doesn't exist.

Open the file specified in path
as a Rugged::Config
file. If path
cannot be found, or the file is an invalid Git config, an exception will be raised.

Public Instance Methods
Get the value for the given config key
. Values are always returned as String
, or nil
if the given key doesn't exist in the Config
file.
cfg['apply.whitespace'] #=> 'fix' cfg['diff.renames'] #=> 'true'
Store the given value
in the Config
file, under the section and name specified by key
. Value can be any of the following Ruby types: String
, true
, false
and Fixnum
.
The config file will be automatically stored to disk.
cfg['apply.whitespace'] = 'fix' cfg['diff.renames'] = true cfg['gc.reflogexpre'] = 90
Delete the given key
from the config file. Return true
if the deletion was successful, or false
if the key was not found in the Config
file.
The config file is immediately updated on disk.
static VALUE rb_git_config_delete(VALUE self, VALUE rb_key) { git_config *config; int error; Data_Get_Struct(self, git_config, config); Check_Type(rb_key, T_STRING); error = git_config_delete_entry(config, StringValueCStr(rb_key)); if (error == GIT_ENOTFOUND) return Qfalse; rugged_exception_check(error); return Qtrue; }
Call the given block once for each key/value pair in the config file. If no block is given, an enumerator is returned.
cfg.each do |key, value| puts "#{key} => #{value}" end
Call the given block once for each key in the config file. If no block is given, an enumerator is returned.
cfg.each_key do |key| puts key end
static VALUE rb_git_config_each_key(VALUE self) { git_config *config; int error, exception; RETURN_ENUMERATOR(self, 0, 0); Data_Get_Struct(self, git_config, config); error = git_config_foreach(config, &cb_config__each_key, &exception); if (error == GIT_EUSER) rb_jump_tag(exception); rugged_exception_check(error); return Qnil; }
Call the given block once for each key/value pair in the config file. If no block is given, an enumerator is returned.

Get the value for the given config key
. Values are always returned as String
, or nil
if the given key doesn't exist in the Config
file.
cfg['apply.whitespace'] #=> 'fix' cfg['diff.renames'] #=> 'true'
static VALUE rb_git_config_get(VALUE self, VALUE rb_key) { git_config *config; git_buf buf = { NULL }; int error; VALUE rb_result; Data_Get_Struct(self, git_config, config); Check_Type(rb_key, T_STRING); error = git_config_get_string_buf(&buf, config, StringValueCStr(rb_key)); if (error == GIT_ENOTFOUND) return Qnil; rugged_exception_check(error); rb_result = rb_str_new_utf8(buf.ptr); git_buf_dispose(&buf); return rb_result; }
Get a list of values for the given config key
. Values are always returned as an Array
of String
, or nil
if the given key doesn't exist in the Config
file.
cfg['apply.whitespace'] #=> ['fix'] cfg['diff.renames'] #=> ['true'] cfg['remote.origin.fetch'] #=> ["+refs/heads/*:refs/remotes/origin/*", "+refs/heads/*:refs/lolol/origin/*"]

Create a snapshot of the configuration.
Provides a consistent, read-only view of the configuration for looking up complex values from a configuration.
static VALUE rb_git_config_snapshot(VALUE self) { git_config *config, *snapshot; Data_Get_Struct(self, git_config, config); rugged_exception_check( git_config_snapshot(&snapshot, config) ); return rugged_config_new(rb_obj_class(self), Qnil, snapshot); }
Store the given value
in the Config
file, under the section and name specified by key
. Value can be any of the following Ruby types: String
, true
, false
and Fixnum
.
The config file will be automatically stored to disk.
cfg['apply.whitespace'] = 'fix' cfg['diff.renames'] = true cfg['gc.reflogexpre'] = 90
static VALUE rb_git_config_store(VALUE self, VALUE rb_key, VALUE rb_val) { git_config *config; const char *key; int error; Data_Get_Struct(self, git_config, config); Check_Type(rb_key, T_STRING); key = StringValueCStr(rb_key); switch (TYPE(rb_val)) { case T_STRING: error = git_config_set_string(config, key, StringValueCStr(rb_val)); break; case T_TRUE: case T_FALSE: error = git_config_set_bool(config, key, (rb_val == Qtrue)); break; case T_FIXNUM: error = git_config_set_int32(config, key, FIX2INT(rb_val)); break; default: rb_raise(rb_eTypeError, "Invalid value; config files can only store string, bool or int keys"); } rugged_exception_check(error); return Qnil; }
Returns the config file represented as a Ruby hash, where each configuration entry appears as a key with its corresponding value.
cfg.to_hash #=> {"core.autolf" => "true", "core.bare" => "true"}
static VALUE rb_git_config_to_hash(VALUE self) { git_config *config; int error; VALUE hash; Data_Get_Struct(self, git_config, config); hash = rb_hash_new(); error = git_config_foreach(config, &cb_config__to_hash, (void *)hash); rugged_exception_check(error); return hash; }
Perform configuration changes in a transaction.
Locks the configuration, executes the given block and stores any changes that were made to the configuration. If the block throws an exception, all changes are rolled back automatically.
During the execution of the block, configuration changes don't get stored to disk immediately, so reading from the configuration will continue to return the values that were stored in the configuration when the transaction was started.
static VALUE rb_git_config_transaction(VALUE self) { git_config *config; git_transaction *tx; VALUE rb_result; int error = 0, exception = 0; Data_Get_Struct(self, git_config, config); git_config_lock(&tx, config); rb_result = rb_protect(rb_yield, self, &exception); if (!exception) error = git_transaction_commit(tx); git_transaction_free(tx); if (exception) rb_jump_tag(exception); else if (error) rugged_exception_check(error); return rb_result; }
