62 This guide provides a detailed description to set up a system suitable to
63 create, check and preview documentation locally. The targeted readership are
64 beginners and people interested in creating documentation.
66 The guide describes the setup of a development system from scratch using the
67 Ubuntu Desktop version installed in a virtual machine. It includes all required
68 steps and also some optional ones that may ease your daily work with this
69 development system. Feel free to adapt it to your needs.
71 In general, formal ONAP documentation uses the reStructuredText markup language
72 and the files have an ``.rst`` extension. They are part of almost every ONAP
73 project and can be found in the ``docs`` directory. The files are automatically
74 processed and you find the final ONAP documentation build hosted on
75 `ReadTheDocs <https://docs.onap.org>`__.
77 Beginning with the 'Frankfurt' release of ONAP, the documentation structure has
78 changed and the support of submodules was removed. Although large parts of this
79 guide are valid for earlier releases, the relevance has been limited.

110 processors, cores or hard disk space.
115 Follow the instructions of your virtualization solution to install Ubuntu in a
116 virtual machine. Log in after the installation has finished.
118 -------------------------------------------------------------------------------
123 .. note:: This section is optional and should not be understood as a
129 The following actions are performed on the Ubuntu desktop. You may use the
130 desktop search function :guilabel:`Show Applications` (the |ShowApp| symbol in
131 the bottom left corner) to find the required applications. Later on you need to
132 start also a :guilabel:`Terminal` window from here.
137 Open :guilabel:`Software Updater` and update already installed Ubuntu packages.
138 You may need to restart the system afterwards.
143 Open :guilabel:`Language Support`. You are asked to complete the installation.
144 Select the :guilabel:`Install` button to complete. Continue in the
145 :guilabel:`Language Support` window and open
146 :guilabel:`Install / Remove Languages`. Then select your preferred
147 :guilabel:`<LANGUAGE>`. Choose :guilabel:`Apply` to install the additional
153 Continue to the :guilabel:`Regional Formats` tab. Select a
154 :guilabel:`<FORMAT>` to show e.g. date, time and numbers in your preferred
155 format. Press :guilabel:`Close` to close the window.
160 To change the keyboard layout used e.g. in command line windows, open
161 :guilabel:`Settings`. Navigate to :guilabel:`Region & Language`. At
162 :guilabel:`Input Sources` press the :guilabel:`+` sign. Select your preferred
163 :guilabel:`<INPUTSOURCE>` and use :guilabel:`Add` to add it. Move it to the top
164 of the list using drag and drop. Close the window. You may need to logout from
165 the UI and login again to make your changes effective.
170 Open :guilabel:`Settings`. Navigate to :guilabel:`Privacy` >
171 :guilabel:`Screen Lock` and change settings for :guilabel:`Blank Screen Delay`
172 and :guilabel:`Automatic Screen Lock` to values of your choice. Close the
175 -------------------------------------------------------------------------------
177 Disable sudo password for your user
178 ===================================
180 .. warning:: This section is optional and should not be understood as a
181 requirement. Disabling password authentication for all commands is very
182 convenient at use **but it strongly exposes your system to malicious code**.
183 For a system dedicated to development it might be OK, but not for a
184 production system! Handle with care. You have been warned.
186 Open a :guilabel:`Terminal` window and start the ``visudo`` editor with ...
192 and add ``<USER> ALL=(ALL) NOPASSWD:ALL`` to the end of the file. Replace
193 ``<USER>`` with your user name.
195 -------------------------------------------------------------------------------
197 Install python3 related packages
198 ================================
200 .. note:: The main python3 package is preinstalled in Ubuntu 20.04.
202 Open a :guilabel:`Terminal` window and update the package management system
211 Install python3 related packages with ...
215 sudo apt install -y python3-pip
216 sudo apt install -y build-essential
217 sudo apt install -y libssl-dev
218 sudo apt install -y libffi-dev
219 sudo apt install -y python3-dev
220 sudo apt install -y python3-venv
223 Check the python3 version with ...
229 -------------------------------------------------------------------------------
231 Install git and documentation related packages
232 ==============================================
234 Install the required packages with ...
238 sudo apt install -y git
239 sudo apt install -y git-review
240 sudo apt install -y python3-sphinx
241 sudo apt install -y python3-doc8
242 sudo apt install -y curl
243 sudo apt install -y jq
245 Check the git version with ...
251 -------------------------------------------------------------------------------
253 Create virtual environment and activate
254 =======================================
256 In this guide, virtual environments are generally located in your home
257 directory under ``~/environments``. For the development of ONAP documentation
258 the virtual environment ``onapdocs`` is created. The full path is consequently
259 ``~/environments/onapdocs``.
266 python3 -m venv onapdocs
267 cd ~/environments/onapdocs
270 To indicate that you are now working in an virtual environment, the prompt of
271 your terminal has changed. Now it starts with ``(onapdocs)``.
273 -------------------------------------------------------------------------------
275 Install required Sphinx packages in activated environment
276 =========================================================
278 It is :strong:`important` to activate the ``onapdocs`` environment before you
279 continue. If not already done, activate environment with ...
283 cd ~/environments/onapdocs
286 To indicate that you are now working in an virtual environment, the prompt of
287 your terminal has changed. Now it starts with ``(onapdocs)``.
289 .. important:: Now you are installing packages only for the 'onapdocs' virtual
295 pip3 install lfdocs-conf
299 .. note:: The ``lfdocs-conf`` package requires multiple, additional libraries.
300 They are loaded automatically.
302 .. tip:: Remember the path
303 ``/home/<USER>/environments/onapdocs/bin/sphinx-build``, you need it later
304 to configure a VSC extension.
306 -------------------------------------------------------------------------------
308 Install Visual Studio Code (VSC) and update already installed applications
309 ==========================================================================
311 The following actions are performed on the Ubuntu desktop. You may use the
312 desktop search function :guilabel:`Show Applications` (the |ShowApp| symbol in
313 the bottom left corner) to find the required applications.
315 Open :guilabel:`Ubuntu Software` > :guilabel:`Development`, select
316 :guilabel:`code` (Visual Studio Code) and press :guilabel:`Install` to install
317 the integrated development environment (IDE).
319 Open :guilabel:`Ubuntu Software` > :guilabel:`Updates` to ensure that your
320 installed applications are up to date.
322 -------------------------------------------------------------------------------
324 Clone example repo (no LF account)
325 ==================================
330 For a quick start you can clone e.g. the ``doc`` repository even without a
331 Linux Foundation (LF) account with ...
335 cd ~/environments/onapdocs
336 git clone --branch master https://git.onap.org/doc/ ./doc
338 -------------------------------------------------------------------------------
340 Clone example repo (LF account used)
341 ====================================
343 Prerequisite configuration
344 --------------------------
346 If you plan to contribute to the ONAP community and you want to submit changes
347 to a specific project later on, please refer to the
348 `ONAP Developer Wiki <https://wiki.onap.org>`__ to get information about all
349 the prerequisite details.
351 If you already have a LF account and you have shared your public ssh key you
352 can finalize the configuration of this development system by updating your ssh
353 configuration in the ``~/.ssh`` directory by copying over ``config``,
354 ``id_rsa`` and ``id_rsa.pub``
356 In addition you configure ``git`` and ``git-review`` with ...
360 git config --global user.email "<GIT-EMAIL>"
361 git config --global user.name "<GIT-USER>"
362 git config --global --add gitreview.username "<GIT-USER>"
363 git config --global gitreview.remote origin
365 Replace ``<GIT-EMAIL>`` and ``<GIT-USER>`` with your account details.
372 cd ~/environments/onapdocs
373 git clone --recurse-submodules ssh://<GIT-USER>@gerrit.onap.org:29418/doc
375 -------------------------------------------------------------------------------
377 Start VSC in the correct directory
378 ==================================
380 Start VSC (always) in the ``docs`` directory of your repository. For the
381 ``doc`` repository used in this example do this with ...
389 .. important:: Don't forget the ``.`` (dot) when you start Visual Studio Code.
391 .. tip:: ``~/environments/onapdocs/doc/docs`` is now your
392 ``${workspaceFolder}`` because you have started VSC (``code .``) from here!
394 -------------------------------------------------------------------------------
396 Disable Telemetry of VSC
397 ========================
399 In case you want to disable telemetry functionality of Visual Studio Code, open
400 :guilabel:`File` > :guilabel:`Preferences` > :guilabel:`Telemetry Settings` and
401 turn it ``off`` in the selection field.
403 In an older version of VSC you alternatively need to open
404 :guilabel:`File` > :guilabel:`Preferences` > :guilabel:`Settings` and
405 search for ``telemetry``. Then uncheck
406 :guilabel:`Telemetry: Enable Crash Reporter` and
407 :guilabel:`Telemetry: Enable Telemetry`
409 .. warning:: Extensions may be collecting their own usage data and are not
410 controlled by the ``telemetry.enableTelemetry`` setting. Consult the
411 specific extension's documentation to learn about its telemetry
412 reporting and whether it can be disabled. See also
413 https://code.visualstudio.com/docs/getstarted/telemetry
415 -------------------------------------------------------------------------------
417 Install VSC extensions and configure reStructuredText extension
418 ===============================================================
420 Install VSC extensions
421 ----------------------
423 Extension bring additional power to Visual Studio Code. To search and install
424 them, open :guilabel:`File` > :guilabel:`Preferences` > :guilabel:`Extensions`
425 or use the keyboard shortcut ``[Ctrl+Shift+X]``. Then enter the name of the
426 extension in the :guilabel:`Search Extensions in Marketplace` window.
427 Press :guilabel:`Install` if you have found the required extension.
431 +--------------------------------------+---------------------------------------+---------+
432 | Python | ms-python.python | latest |
433 +--------------------------------------+---------------------------------------+---------+
434 | reStructuredText | lextudio.restructuredtext | 169.0.0 |
435 +--------------------------------------+---------------------------------------+---------+
436 | reStructuredText Syntax highlighting | trond-snekvik.simple-rst | latest |
437 +--------------------------------------+---------------------------------------+---------+
438 | Code Spell Checker | streetsidesoftware.code-spell-checker | latest |
439 +--------------------------------------+---------------------------------------+---------+
440 | Prettier | esbenp.prettier-vscode | latest |
441 +--------------------------------------+---------------------------------------+---------+
442 | GitLens | eamodio.gitlens | latest |
443 +--------------------------------------+---------------------------------------+---------+
445 .. note:: Use the reStructuredText extension version 169.0.0 or lower to
446 avoid problems with the preview. You need to downgrade after the initial
449 Configure reStructuredText extension
450 ------------------------------------
452 To configure ``reStructuredText`` extension, open :guilabel:`File` >
453 :guilabel:`Preferences` > :guilabel:`Extensions` or use the keyboard shortcut
454 ``[Ctrl+Shift+X]``. Then enter ``reStructuredText`` in the
455 :guilabel:`Search Extensions in Marketplace` window. After you have found the
456 extension press :guilabel:`Manage` (the little |GearSymb| symbol on the right
457 bottom) and select :guilabel:`Extension Settings`. A new windows in VSC shows
458 all the parameters. Change the following ones:
460 :strong:`Restructuredtext › Linter: Executable Path`
463 :strong:`Restructuredtext › Linter: Name`
466 :strong:`Restructuredtext: Sphinx Build Path`
467 ``/home/<USER>/environments/onapdocs/bin/sphinx-build``
469 Replace ``<USER>`` with your user name.
471 Only in case the preview creates an error message, try ...
473 :strong:`Restructuredtext: Conf Path`
474 ``${workspaceFolder}/docs``
476 Close the :guilabel:`Extension Settings` window.
478 Close VSC and start it again with the ``code .`` command.
480 -------------------------------------------------------------------------------
482 Open a .rst file and preview it in VSC
483 ======================================
488 Select :guilabel:`View` > :guilabel:`Explorer`. Or use the |FileExpl| symbol in
489 the upper left corner. Expand the ``docs`` folder by clicking on the ``>``
490 symbol. Select the file ``index.rst``. The code shows up in the right pane
493 Alternatively you can open this guide and see how it looks like in the
494 reStructuredText format. It can be found in ``docs/guides/onap-documentation``
495 and is named ``setup-of-a-doc-dev-system.rst``.
500 You may see problems with the reStructuredText markup because the code is
501 underlined in various colors. For the details select :guilabel:`View` >
502 :guilabel:`Problems` to open an additional window at the bottom of VSC.
504 When you select a specific entry in the problem list, the code window is
505 updated to show the related line in the code.
510 Now select :guilabel:`Preview To The Side` (the |Preview| symbol on the top
511 right) or use keyboard shortcut ``[Ctrl+k Ctrl+r]`` to open the preview window
512 on the right hand side. This may take a few seconds. The preview shows up and
513 renders the ``index.rst`` as it would look like on ReadTheDocs.
518 The learnings are ...
521 - Start VSC always in the ``docs`` directory of the repository. Use the
522 command ``code .``. Then navigate via VSC's :guilabel:`Explorer`
523 |FileExpl| to the directory which contains the file you like to edit. VSC
524 may ask you, which ``conf.py`` VSC should use. Choose the one which
525 resides in the directory where you have started VSC. Check also the (blue)
526 bottom line of VSC. There you see which ``conf.py`` is currently in use.
527 The content of ``conf.py`` affects how the documentation is presented.
528 - VSC may claim that some packages require an update. This can be easily
529 fixed. VSC offers automatically to install or update the package.
530 - VSC may ask you to install ``snooty``. Please install.
531 - Select the correct environment in the (blue) bottom line
532 ``'onapdocs':venv``. Have also a view on the other interesting
533 information (e.g. the ``conf.py`` which is currently in use).
534 - First, close and reopen preview if preview is not shown properly.
535 - Second, close and reopen VSC if preview is not shown properly.
536 - Save your file if an error does not disappear after you have corrected it.
537 - You can not navigate within the document structure by clicking the links
538 in the preview. You always have to choose the correct file in the VSC
539 :guilabel:`Explorer` window.
544 Congratulations, well done! You have configured a system well suited to
545 develop ONAP documentation and to master the challenges of reStructuredText.
546 Now have a look at all the different elements of reStructuredText and learn how
547 to use them properly. Or maybe you like to do some optional configurations at
550 -------------------------------------------------------------------------------
552 Optional VSC Configuration
553 ==========================
558 To add a ruler that indicates the line end at 79 characters, open
559 :guilabel:`File` > :guilabel:`Preferences` > :guilabel:`Settings` and enter
560 ``ruler`` in the :guilabel:`Search settings` field. In
561 :guilabel:`Editor: Rulers` click on :guilabel:`Edit in settings.json` and add
562 the value ``79``. The result should look like this:
570 Disable Synchronized Scrolling of Editor and Preview
571 ----------------------------------------------------
573 To disable the synchronized scrolling of editor and preview, open
574 :guilabel:`File` > :guilabel:`Preferences` > :guilabel:`Settings` and
575 search for ``Restructuredtext › Preview: Scroll``. Then uncheck
576 :guilabel:`Restructuredtext › Preview: Scroll Editor With Preview` and
577 :guilabel:`Restructuredtext › Preview: Scroll Preview With Editor`
579 -------------------------------------------------------------------------------
