21 The sync command synchronizes a project with its build configurations.
22 The first form (no --upgrade or --patch and only pkg-args arguments, if
23 any, are specified) upgrades the project packages to the latest ver‐
24 sion/iteration, adjusts their dependencies according to the latest man‐
25 ifest information, and updates the lockfile.
26
27 If no project or package directory is specified, then the current work‐
28 ing directory is assumed. If no configuration is specified, then the
29 default configurations are assumed. See bdep-projects-configs(1) for
30 details on specifying projects and configurations. Optional pkg-args
31 are the additional dependency packages and/or configuration variables
32 to pass to the underlying bpkg-pkg-build(1) command.
33
34 The second form (no arguments but either --upgrade or --patch is speci‐
35 fied), in addition to the first form's functionality, also upgrades or
36 patches immediate (by default or if --immediate|-i is specified) or all
37 (if --recursive|-r is specified) dependencies of the specified project
38 packages. If no project packages are specified explicitly, then this
39 form upgrades or patches dependencies of all the initialized packages
40 in a project.
41
42 The third form (one or more dep-spec arguments are specified), in addi‐
43 tion to the first form's functionality, also upgrades (by default or if
44 --upgrade is specified) or patches (if --patch is specified) the speci‐
45 fied dependencies. If --immediate|-i or --recursive|-r is specified,
46 then it also upgrades or patches the immediate or all dependencies of
47 the specified dependencies, respectively. Alternative to --upgrade and
48 --patch, the desired upgrade (or downgrade) version can be specified
49 explicitly.
50
51 Note also that --immediate|-i or --recursive|-r can only be specified
52 with an explicit --upgrade or --patch.
53
54 Configuration variables can be specified to only apply to specific
55 packages in pkg-args and dep-spec using the argument grouping mechanism
56 (bdep-argument-grouping(1)). Additionally, packages in pkg-args can be
57 placed into specific linked configurations by specifying the configura‐
58 tion with one of the --config* options (or @ notation) using the same
59 grouping mechanism.
60
61 If during synchronization a build-time dependency is encountered and
62 there is no build configuration of a suitable type associated with the
63 project, then the user is prompted (unless the respective --cre‐
64 ate-*-config option is specified) to automatically create such a con‐
65 figuration and associate it with the project. See bpkg-cfg-create(1)
66 for background on configuration types.
67
69 As an example, consider project prj with two packages, foo and libfoo:
70
71 prj/
72 |-- foo/
73 `-- libfoo/
74
75 Assuming foo and libfoo have been initialized in the default build con‐
76 figuration, the following invocations illustrate the common sync use
77 cases (the current working directory is shown before the shell prompt).
78
79 Synchronize foo and libfoo with the default configuration:
80
81 prj/$ bdep sync
82
83 The same (all initialized packages in a project are always synchronized
84 at once):
85
86 prj/$ cd foo
87 foo/$ bdep sync
88
89 Add a dependency on libx with sync fetching and configuring a suitable
90 version:
91
92 foo/$ edit manifest # Add 'depends: libx ^1.0.0'
93 foo/$ bdep sync
94
95 Upgrade all the immediate dependencies of foo:
96
97 foo/$ bdep sync -u
98
99 Upgrade all the dependencies of all the initialized packages in a
100 project recursively:
101
102 foo/$ cd ../
103 prj/$ bdep sync -u -r
104
105 Upgrade libx to the latest version:
106
107 prj/$ bdep sync libx
108
109 Upgrade libx and its immediate dependencies to the latest version:
110
111 prj/$ bdep sync -u -i libx
112
113 Upgrade libx to the latest patch version:
114
115 prj/$ bdep sync -p libx
116
117 Upgrade libx and all its dependencies recursively to the latest patch
118 version.
119
120 prj/$ bdep sync -p -r libx
121
122 Upgrade libx to version 1.2.3.
123
124 prj/$ bdep sync libx/1.2.3
125
126 Upgrade libx to version 1.2.3 and patch all its dependencies, recur‐
127 sively:
128
129 prj/$ bdep sync -p -r libx/1.2.3
130
132 --upgrade|-u
133 Upgrade dependencies to the latest available version that satis‐
134 fies all the constraints.
135
136 --patch|-p
137 Upgrade dependencies to the latest available patch version that
138 satisfies all the constraints.
139
140 --immediate|-i
141 Also upgrade or patch immediate dependencies.
142
143 --recursive|-r
144 Also upgrade or patch all dependencies, recursively.
145
146 --yes|-y
147 Don't prompt for confirmation when up/down-grading dependencies.
148
149 --disfigure
150 Disfigure project packages during synchronization effectively
151 causing their from-scratch reconfiguration.
152
153 --fetch|-f
154 Perform the fetch command prior to synchronization.
155
156 --fetch-full|-F
157 Perform the fetch --full command prior to synchronization.
158
159 --create-host-config
160 Create a configuration for build-time dependencies without
161 prompt.
162
163 --create-build2-config
164 Create a configuration for build system module dependencies
165 without prompt.
166
167 --implicit
168 Perform implicit synchronization. This mode is normally used by
169 other tools (for example, a build system hook) to ensure
170 projects and configurations are synchronized. To improve perfor‐
171 mance, especially for the "everything is already synchronized"
172 case, sync executed in this mode assumes that no configuration
173 flags (see bdep-config(1)) have changed since the last explicit
174 synchronization. It also does not search for a project in the
175 current working directory – if any, its directory should be
176 specified explicitly with --config|-c.
177
178 --all|-a
179 Use all build configurations.
180
181 --config|-c dir
182 Specify the build configuration as a directory.
183
184 --directory|-d dir
185 Assume project/package is in the specified directory rather than
186 in the current working directory.
187
188 --config-name|-n name
189 Specify the build configuration as a name.
190
191 --config-id num
192 Specify the build configuration as an id.
193
195 The common options are summarized below with a more detailed descrip‐
196 tion available in bdep-common-options(1).
197
198 -v Print essential underlying commands being executed.
199
200 -V Print all underlying commands being executed.
201
202 --quiet|-q
203 Run quietly, only printing error messages.
204
205 --verbose level
206 Set the diagnostics verbosity to level between 0 and 6.
207
208 --stdout-format format
209 Representation format to use for printing to stdout.
210
211 --jobs|-j num
212 Number of jobs to perform in parallel.
213
214 --progress
215 Display progress indicators for long-lasting operations, such as
216 network transfers, building, etc.
217
218 --no-progress
219 Suppress progress indicators for long-lasting operations, such
220 as network transfers, building, etc.
221
222 --bpkg path
223 The package manager program to be used for build configuration
224 management.
225
226 --bpkg-option opt
227 Additional option to be passed to the package manager program.
228
229 --build path
230 The build program to be used to build packages.
231
232 --build-option opt
233 Additional option to be passed to the build program.
234
235 --curl path
236 The curl program to be used for network operations.
237
238 --curl-option opt
239 Additional option to be passed to the curl program.
240
241 --pager path
242 The pager program to be used to show long text.
243
244 --pager-option opt
245 Additional option to be passed to the pager program.
246
247 --options-file file
248 Read additional options from file.
249
250 --default-options dir
251 The directory to load additional default options files from.
252
253 --no-default-options
254 Don't load default options files.
255
257 See bdep-default-options-files(1) for an overview of the default op‐
258 tions files. For the sync command the search start directory is the
259 project directory, except for the implicit mode for which only the pre‐
260 defined directories (system, etc) are searched in. The following op‐
261 tions files are searched for in each directory and, if found, loaded in
262 the order listed:
263
264 bdep.options
265 bdep-{sync|sync-implicit}.options # (mode-dependent)
266
267 The following sync command options cannot be specified in the default
268 options files:
269
270 --directory|-d
271 --implicit
272 --config|-c
273
275 The BDEP_SYNC environment variable can be used to suppress automatic
276 synchronization on build system invocation. If set, auto-synchroniza‐
277 tion will only be performed if the variable's value is true or 1. The
278 ability to suppress auto-synchronization can be useful when you don't
279 have usable bdep and/or bpkg.
280
281 To avoid recursive re-synchronization, the sync command also maintains
282 the BDEP_SYNCED_CONFIGS environment variable. It contains a space-sepa‐
283 rated, "-quoted list of configuration paths that have been or are being
284 synchronized by the current bdep invocation chain. The sync command ex‐
285 amines this variable and silently ignores synchronization requests that
286 have been or are already being performed.
