|
|
||||||
non-exclusive license:
|
|
||||||
|
|
||||||
(a) under intellectual property rights (other than patent or trademark)

Licensable by such Contributor to use, reproduce, make available,

2.2. Effective Date
|
|
||||||
|
|
||||||
The licenses granted in Section 2.1 with respect to any Contribution

|
||||||
distributes such Contribution.
|
|
||||||
|
|
||||||
2.3. Limitations on Grant Scope
|
|
||||||
|
|
||||||
The licenses granted in this Section 2 are the only rights granted under
|
|
||||||
this License. No additional rights or licenses will be implied from the
|
|
||||||
distribution or licensing of Covered Software under this License.
|
|
||||||
Notwithstanding Section 2.1(b) above, no patent license is granted by a
|
|
||||||
Contributor:
|
|
||||||
|
|
||||||
(a) for any code that a Contributor has removed from Covered Software;
|
|
||||||
or
|
|
||||||
|
|
||||||
(b) for infringements caused by: (i) Your and any other third party's
|
|
||||||
modifications of Covered Software, or (ii) the combination of its
|
|
||||||
Contributions with other software (except as part of its Contributor
|
|
||||||
Version); or
|
|
||||||
|
|
||||||
(c) under Patent Claims infringed by Covered Software in the absence of
|
|
||||||
its Contributions.
|
|
||||||
|
|
||||||
This License does not grant any rights in the trademarks, service marks,
|
|
||||||
or logos of any Contributor (except as may be necessary to comply with
|
|
||||||
the notice requirements in Section 3.4).
|
|
||||||
|
|
||||||
2.4. Subsequent Licenses
|
|
||||||
|
|
||||||
No Contributor makes additional grants as a result of Your choice to
|
|
||||||
distribute the Covered Software under a subsequent version of this
|
|
||||||
License (see Section 10.2) or under the terms of a Secondary License (if
|
|
||||||
permitted under the terms of Section 3.3).
|
|
||||||
|
|
||||||
2.5. Representation
|
|
||||||
|
|
||||||
Each Contributor represents that the Contributor believes its
|
|
||||||
Contributions are its original creation(s) or it has sufficient rights
|
|
||||||
to grant the rights to its Contributions conveyed by this License.
|
|
||||||
|
|
||||||
2.6. Fair Use
|
|
||||||
|
|
||||||
This License is not intended to limit any rights You have under

|
||||||
applicable copyright doctrines of fair use, fair dealing, or other
|
|
||||||
equivalents.
|
|
||||||
|
|
||||||
2.7. Conditions
|
|
||||||
|
|
||||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
|
|
||||||
in Section 2.1.
|
|
||||||
|
|
||||||
3. Responsibilities
|
|
||||||
-------------------
|
|
||||||
|
|
||||||
3.1. Distribution of Source Form
|
|
||||||
|
|
||||||
All distribution of Covered Software in Source Code Form, including any
|
|
||||||
Modifications that You create or to which You contribute, must be under
|
|
||||||
the terms of this License. You must inform recipients that the Source
|
|
||||||
Code Form of the Covered Software is governed by the terms of this
|
|
||||||
License, and how they can obtain a copy of this License. You may not
|
|
||||||
attempt to alter or restrict the recipients' rights in the Source Code
|
|
||||||
Form.
|
|
||||||
|
|
||||||
3.2. Distribution of Executable Form
|
|
||||||
|
|
||||||
If You distribute Covered Software in Executable Form then:
|
|
||||||
|
|
||||||
(a) such Covered Software must also be made available in Source Code
|
|
||||||
Form, as described in Section 3.1, and You must inform recipients of
|
|
||||||
the Executable Form how they can obtain a copy of such Source Code
|
|
||||||
Form by reasonable means in a timely manner, at a charge no more
|
|
||||||
than the cost of distribution to the recipient; and
|
|
||||||
|
|
||||||
(b) You may distribute such Executable Form under the terms of this
|
|
||||||
License, or sublicense it under different terms, provided that the
|
|
||||||
license for the Executable Form does not attempt to limit or alter
|
|
||||||
the recipients' rights in the Source Code Form under this License.
|
|
||||||
|
|
||||||
3.3. Distribution of a Larger Work
|
|
||||||
|
|
||||||
You may create and distribute a Larger Work under terms of Your choice,
|
|
||||||
provided that You also comply with the requirements of this License for
|
|
||||||
the Covered Software. If the Larger Work is a combination of Covered
|
|
||||||
Software with a work governed by one or more Secondary Licenses, and the
|
|
||||||
Covered Software is not Incompatible With Secondary Licenses, this
|
|
||||||
License permits You to additionally distribute such Covered Software
|
|
||||||
under the terms of such Secondary License(s), so that the recipient of
|
|
||||||
the Larger Work may, at their option, further distribute the Covered
|
|
||||||
Software under the terms of either this License or such Secondary
|
|
||||||
License(s).
|
|
||||||
|
|
||||||
3.4. Notices
|
|
||||||
|
|
||||||
You may not remove or alter the substance of any license notices
|
|
||||||
(including copyright notices, patent notices, disclaimers of warranty,
|
|
||||||
or limitations of liability) contained within the Source Code Form of
|
|
||||||
the Covered Software, except that You may alter any license notices to
|
|
||||||
the extent required to remedy known factual inaccuracies.
|
|
||||||
|
|
||||||
3.5. Application of Additional Terms
|
|
||||||
|
|
||||||
You may choose to offer, and to charge a fee for, warranty, support,
|
|
||||||
indemnity or liability obligations to one or more recipients of Covered
|
|
||||||
Software. However, You may do so only on Your own behalf, and not on
|
|
||||||
behalf of any Contributor. You must make it absolutely clear that any
|
|
||||||
such warranty, support, indemnity, or liability obligation is offered by
|
|
||||||
You alone, and You hereby agree to indemnify every Contributor for any
|
|
||||||
liability incurred by such Contributor as a result of warranty, support,
|
|
||||||
indemnity or liability terms You offer. You may include additional
|
|
||||||
disclaimers of warranty and limitations of liability specific to any
|
|
||||||
jurisdiction.
|
|
||||||
|
|
||||||
4. Inability to Comply Due to Statute or Regulation
|
|
||||||
---------------------------------------------------
|
|
||||||
|
|
||||||
If it is impossible for You to comply with any of the terms of this
|
|
||||||
License with respect to some or all of the Covered Software due to
|
|
||||||
statute, judicial order, or regulation then You must: (a) comply with
|
|
||||||
the terms of this License to the maximum extent possible; and (b)
|
|
||||||
describe the limitations and the code they affect. Such description must
|
|
||||||
be placed in a text file included with all distributions of the Covered
|
|
||||||
Software under this License. Except to the extent prohibited by statute
|
|
||||||
or regulation, such description must be sufficiently detailed for a
|
|
||||||
recipient of ordinary skill to be able to understand it.
|
|
||||||
|
|
||||||
5. Termination
|
|
||||||
--------------
|
|
||||||
|
|
||||||
5.1. The rights granted under this License will terminate automatically
|
|
||||||
if You fail to comply with any of its terms. However, if You become
|
|
||||||
compliant, then the rights granted under this License from a particular
|
|
||||||
Contributor are reinstated (a) provisionally, unless and until such
|
|
||||||
Contributor explicitly and finally terminates Your grants, and (b) on an
|
|
||||||
ongoing basis, if such Contributor fails to notify You of the
|
|
||||||
non-compliance by some reasonable means prior to 60 days after You have
|
|
||||||
come back into compliance. Moreover, Your grants from a particular
|
|
||||||
Contributor are reinstated on an ongoing basis if such Contributor
|
|
||||||
notifies You of the non-compliance by some reasonable means, this is the
|
|
||||||
first time You have received notice of non-compliance with this License
|
|
||||||
from such Contributor, and You become compliant prior to 30 days after
|
|
||||||
Your receipt of the notice.
|
|
||||||
|
|
||||||
5.2. If You initiate litigation against any entity by asserting a patent
|
|
||||||
infringement claim (excluding declaratory judgment actions,
|
|
||||||
counter-claims, and cross-claims) alleging that a Contributor Version
|
|
||||||
directly or indirectly infringes any patent, then the rights granted to
|
|
||||||
You by any and all Contributors for the Covered Software under Section
|
|
||||||
2.1 of this License shall terminate.
|
|
||||||
|
|
||||||
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
|
|
||||||
end user license agreements (excluding distributors and resellers) which
|
|
||||||
have been validly granted by You or Your distributors under this License
|
|
||||||
prior to termination shall survive termination.

|
||||||
* 6. Disclaimer of Warranty *
|
|
||||||
* ------------------------- *
|
|
||||||
* *
|
|
||||||
* Covered Software is provided under this License on an "as is" *
|
|
||||||
* basis, without warranty of any kind, either expressed, implied, or *
|
|
||||||
* statutory, including, without limitation, warranties that the *
|
|
||||||
* Covered Software is free of defects, merchantable, fit for a *
|
|
||||||
* particular purpose or non-infringing. The entire risk as to the *
|
|
||||||
* quality and performance of the Covered Software is with You. *
|
|
||||||
* Should any Covered Software prove defective in any respect, You *
|
|
||||||
* (not any Contributor) assume the cost of any necessary servicing, *
|
|
||||||
* repair, or correction. This disclaimer of warranty constitutes an *
|
|
||||||
* essential part of this License. No use of any Covered Software is *
|
|
||||||
* authorized under this License except under this disclaimer. *

* 7. Limitation of Liability *
|
|
||||||
* -------------------------- *
|
|
||||||
* *
|
|
||||||
* Under no circumstances and under no legal theory, whether tort *
|
|
||||||
* (including negligence), contract, or otherwise, shall any *
|
|
||||||
* Contributor, or anyone who distributes Covered Software as *
|
|
||||||
* permitted above, be liable to You for any direct, indirect, *
|
|
||||||
* special, incidental, or consequential damages of any character *
|
|
||||||
* including, without limitation, damages for lost profits, loss of *
|
|
||||||
* goodwill, work stoppage, computer failure or malfunction, or any *
|
|
||||||
* and all other commercial damages or losses, even if such party *
|
|
||||||
* shall have been informed of the possibility of such damages. This *
|
|
||||||
* limitation of liability shall not apply to liability for death or *
|
|
||||||
* personal injury resulting from such party's negligence to the *
|
|
||||||
* extent applicable law prohibits such limitation. Some *
|
|
||||||
* jurisdictions do not allow the exclusion or limitation of *
|
|
||||||
* incidental or consequential damages, so this exclusion and *
|
|
||||||
* limitation may not apply to You. *

||||||

8. Litigation
|
|
||||||
-------------
|
|
||||||
|
|
||||||
Any litigation relating to this License may be brought only in the
|
|
||||||
courts of a jurisdiction where the defendant maintains its principal
|
|
||||||
place of business and such litigation shall be governed by laws of that
|
|
||||||
jurisdiction, without reference to its conflict-of-law provisions.
|
|
||||||
Nothing in this Section shall prevent a party's ability to bring
|
|
||||||
cross-claims or counter-claims.
|
|
||||||
|
|
||||||
9. Miscellaneous
|
|
||||||
----------------
|
|
||||||
|
|
||||||
This License represents the complete agreement concerning the subject
|
|
||||||
matter hereof. If any provision of this License is held to be
|
|
||||||
unenforceable, such provision shall be reformed only to the extent
|
|
||||||
necessary to make it enforceable. Any law or regulation which provides
|
|
||||||
that the language of a contract shall be construed against the drafter
|
|
||||||
shall not be used to construe this License against a Contributor.
|
|
||||||
|
|
||||||
10. Versions of the License
|
|
||||||
---------------------------
|
|
||||||
|
|
||||||
10.1. New Versions
|
|
||||||
|
|
||||||
Mozilla Foundation is the license steward. Except as provided in Section
|
|
||||||
10.3, no one other than the license steward has the right to modify or
|
|
||||||
publish new versions of this License. Each version will be given a
|
|
||||||
distinguishing version number.
|
|
||||||
|
|
||||||
10.2. Effect of New Versions
|
|
||||||
|
|
||||||
You may distribute the Covered Software under the terms of the version

||||||
of the License under which You originally received the Covered Software,
|
|
||||||
or under the terms of any subsequent version published by the license
|
|
||||||
steward.
|
|
||||||
|
|
||||||
10.3. Modified Versions
|
|
||||||
|
|
||||||
If you create software not governed by this License, and you want to
|
|
||||||
create a new license for such software, you may create and use a
|
|
||||||
modified version of this License if you rename the license and remove
|
|
||||||
any references to the name of the license steward (except to note that
|
|
||||||
such modified license differs from this License).
|
|
||||||
|
|
||||||
10.4. Distributing Source Code Form that is Incompatible With Secondary
|
|
||||||
Licenses

|
|
||||||
|
|
||||||
## 2.0.1
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||

# `xdg_directories`
|
|
||||||
|
|
||||||
A Dart package for reading XDG directory configuration information on Linux.
|
|
||||||
|
|
||||||
## Getting Started
|
|
||||||
|
|
||||||
On Linux, `xdg` is a system developed by [freedesktop.org](freedesktop.org), a
|
|
||||||
project to work on interoperability and shared base technology for free software
|
|
||||||
desktop environments for Linux.
|
|
||||||
|
|
||||||
This Dart package can be used to determine the directory configuration
|
|
||||||
information defined by `xdg`, such as where the Documents or Desktop directories
|
|
||||||
are. These are called "user directories" and are defined in configuration file
|
|
||||||
in the user's home directory.
|
|
||||||
|
|
||||||
See [this wiki](https://wiki.archlinux.org/index.php/XDG_Base_Directory) for
|
|
||||||
more details of the XDG Base Directory implementation.
|
|
||||||
|
|
||||||
To use this package, the basic XDG values for the following are available via a Dart API:
|
|
||||||
|
|
||||||
- `dataHome` - The single base directory relative to which user-specific data
|
|
||||||
files should be written. (Corresponds to `$XDG_DATA_HOME`).
|
|
||||||
|
|
||||||
- `configHome` - The a single base directory relative to which user-specific
|
|
||||||
configuration files should be written. (Corresponds to `$XDG_CONFIG_HOME`).
|
|
||||||
|
|
||||||
- `dataDirs` - The list of preference-ordered base directories relative to
|
|
||||||
which data files should be searched. (Corresponds to `$XDG_DATA_DIRS`).
|
|
||||||
|
|
||||||
- `configDirs` - The list of preference-ordered base directories relative to
|
|
||||||
which configuration files should be searched. (Corresponds to
|
|
||||||
`$XDG_CONFIG_DIRS`).
|
|
||||||
|
|
||||||
- `cacheHome` - The base directory relative to which user-specific
|
|
||||||
non-essential (cached) data should be written. (Corresponds to
|
|
||||||
`$XDG_CACHE_HOME`).
|
|
||||||
|
|
||||||
- `runtimeDir` - The base directory relative to which user-specific runtime
|
|
||||||
files and other file objects should be placed. (Corresponds to
|
|
||||||
`$XDG_RUNTIME_DIR`).
|
|
||||||
|
|
||||||
- `getUserDirectoryNames()` - Returns a set of the names of user directories
|
|
||||||
defined in the `xdg` configuration files.
|
|
||||||
|
|
||||||
- `getUserDirectory(String dirName)` - Gets the value of the user dir with the
|
|
||||||
given name. Requesting a user dir that doesn't exist returns `null`. The
|
|
||||||
`dirName` argument is case-insensitive. See [this
|
|
||||||
wiki](https://wiki.archlinux.org/index.php/XDG_user_directories) for more
|
|
||||||
details and what values of `dirName` might be available.
