Local Setup

This section describes the best practices about what and how should be done in order to run the documentation locally.

Prerequisites

Install Docker (Community Edititon(CE) is enough) - please use the official Docker installation guide. Accept the default installation instructions (use Linux containers, etc.)
- From the Docker Settings window, share the drive where the documentation repos reside with Docker.
Install Node.js and restart the machine.
Choose a repo you want to contribute to (e.g. https://github.com/telerik/xaml-docs.git, we will refer to that repo later as 'MY-REPO')
Pull the documentation repo onto your hard drive (e.g. "D:\Work\xaml-docs"). We will refer to the local path, where the documentation repo is cloned, as 'DOCS-PATH'.

IMPORTANT: For products such as Kendo UI for jQuery, UI for ASP.NET MVC and UI for ASP.NET Core, the documentation is part of source code repo. For these products, 'DOCS-PATH' is actually a nested folder in the cloned repo, e.g. "D:\Work\kendo-ui-core\docs".

IMPORTANT: In case you are not able to install and use Docker, please go to Instructions (without Docker), otherwise continue to the next section.

Instructions (with Docker)

Clone the current (seed) repo

git clone git@github.com:telerik/docs-seed.git

Go to the directory in which you've pulled it (e.g. D:\Work\docs-seed)
Open a terminal of your choice (e.g., gitBash)
Run the following command by passing the DOCS-PATH path (the quotes are mandatory):

sh copy_local.sh "D:\Work\xaml-docs"

If you are running the documentation on a MacOS or another OS where the robocopy command is unavailable, you have to pass a second parameter to the copy_local.sh script: sh copy_local.sh "D:\Work\xaml-docs" true

Go to the DOCS-PATH directory
Open a terminal of your choice (e.g., gitBash)
Execute the following bash command in the root folder (where the Dockerfile is located)

sh start-docs.sh

This is it! You can find the documentation site on server address which is written in the terminal: http://0.0.0.0:4000/. If you can't open the previous URL, replace the '0.0.0.0' with 'localhost' - http://localhost:4000.

For example, for WPF documentation this would be: http://0.0.0.0:4000/devtools/wpf/

If you want to stop the web site and the container in which it has been served, navigate to the terminal in which you've executed the previous command and press CTRL+C.

For WPF and Silverlight, see how to pass an additional config file.

Instructions (without Docker)

Install ruby 2.3.3 (64bit or 32bit)
Install Ruby DevKit (64bit or 32bit), see the instructions
Ensure everything is correctly installed, especially if you have previous versions installed on the machine (e.g. check whether the 'config.yml' file in the DevKit root folder contains the correct path to the ruby folder and check whether the system environmnet variables are correctly set).

For more info on the above you can read the following article - http://jekyll-windows.juthilo.com/1-ruby-and-devkit/.

Install bundler (if you have already installed, continue to the next step) by executing gem install bundler
Clone the current (seed) repo

git clone git@github.com:telerik/docs-seed.git

Go to the directory in which you've pulled the current (seed) repo (e.g. D:\Work\docs-seed)
Open a terminal of your choice (e.g., gitBash)
Run the following command by passing the DOCS-PATH path (the quotes are mandatory):

sh copy_local.sh "D:\Work\xaml-docs"

Go to the DOCS-PATH directory
Open a terminal of your choice (e.g., gitBash)
Install gems by executing bundle install
Execute the following bash command in the root folder

bundle exec jekyll serve

This is it! You can find the documentation site on server address which is written in the terminal: http://127.0.0.1:4000/. If you can't open the previous URL, replace the '127.0.0.1' with 'localhost' - http://localhost:4000.

For example, for WPF documentation this would be: http://127.0.0.1:4000/devtools/wpf/

If you want to change the host or port just pass the --host or --port arguments to the command above as an addition (e.g. bundle exec jekyll serve --host=0.0.0.0 --port=1234).

Troubleshooting

Does Not Serve

You executed sh start-docs.sh but you did not see any Jekyll output. Instead, the command ended with

the input device is not a TTY. If you are using mintty, try prefixing the command with 'winpty'

This happens whtn using Git Bash with the MinTTY console. This console does not allow combinations such as Ctrl+C to pass to the Docker container and so you get such an error.

The easiest way to resolve it is to prefix the command with winpty:

winpty sh start-docs.sh

An alternative is to re-install Git Bash and choose the default Windows terminal this time. You can read more detailes in the following post: Docker for Windows: Interactive Sessions in MinTTY Git Bash.

Ctrl+C Does not Work

When you want to stop serving the docs, you may have to repeat the Ctrl+C command or press Enter after it.

.gitignore is Always Modified

The scripts that copy the seed repo to the content repo (MY-REPO), also update the .gitignore file so as to avoid creating unstanged changes with work files that must not be commited. If you keep getting the .gitignore checked out, see what the change is with the original and commit to your repo the version that matches what the tool generates.

Performance

Docker is a resource-intensive tool. If you are not using it on a daily basis, consider preventing it from running on startup. Right click its tray icon > Settings > General, uncheck "Start Docker when you log in". This can save you time when booting up/logging in, but you will need to explicitly start Docker before working on documentation.

Also, it tends to require a lot of HDD space, which may be an issue if you are running it on an SSD drive with limited capacity. You can reduce its quota by opening the Settings dialog > Advanced and either changing the image location, and/or reducing its max size. This also lets you limit its RAM consumption.

Encoding Problems While Building

When you try to build the documentation site, you could see an error including the following incomplete "\n" on UTF-16LE message. It might be caused because of different things. Use the following steps to try to fix or workaround it:

Ensure Node.js is installed by typing node -v in a command prompt. The machine must be restarted after a Node.js installation.
Allow files with long path using the following command:

git config --system core.longpaths true

Add the following System Environment Variables
- JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
- LANG: en_GB.UTF-8
Modify the runtimes.rb file in the execJs gem by changing UTF-16LE with UTF-8 values - see detailed instructions here or here. The runtimes.rb file is located in [Ruby Installation folder]\lib\ruby\gems\2.3.0\gems\execjs-2.7.0\lib\execjs

Extra Features

You can benefit from the following features:

additional config file
live sync
build without serve
build site partially

Additional Config File

In case you want to add an additional config.yml file, pass it to the above command as follows:

sh start-docs.sh _silverlight.yml

LiveSync

To be able to monitor the changes you are making on the built documentation, execute the following command in a new terminal in the root directory of the site:

sh watch.sh

Prerequisite: If you haven't yet, please install Node.js.

Only Build

To only run jekyll build and not jekyll serve, you need to execute the following bash command:

sh build-docs.sh

This can be useful if you want to (or already have) setup local IIS to point to the _site folder in your documentation repo. This allows you to also test redirects that jekyll serve does not support.

Build Site Partially

If you want to speed up the site's building time, you can pass only a specific part(s) of it - the folders you want to include in the site.

This could be achieved by executing the sh modify-config.sh script with passing the corresponding arguments which are:

-i,--include - the folders you want to include in the final build. Multiple folders are separated with comma. No spaces are allowed
-c,--config - path to an additional config file which shall be used for the build (see here more about additional config file
-s,--serve - accepts true/false - indicates whether the Jekyll should only build, or build and serve
-d,--docker - accepts true/false - indicates whether the site shuold be run in Docker (set --docker=true if you're using Docker)

EXAMPLE: Let's say that you want to build only the documentation for 2 controls - Barcode and Chart, you are using Docker and you have an extra config YAML file. Then you have to open a terminal and execute the following:

sh modify-config.sh --include=controls/barcode,controls/Chart --docker=true --config=_extra.yml

Build API Reference

There is infrastructure that uses DocFx to generate an API reference portion of the site for you. To use it, you need the following:

the docs-seed repo on your build machine. This should already be set up.
an API ref link in your table of contents on the left. To enable it, add the following line in your _config.yml file:

_config.yml
```
  api_reference_url: "api/"
```
a folder on a shared network location that the build can access, and that contains the .dll and .xml files you want generated.
the assets for building the API reference in your repo. You can start by copying existing assets, for example from Winforms: https://github.com/telerik/winforms-docs/tree/master/_assetsApi. Note that the templates are plain HTML for the time being, so you must keep them in sync with your actual repo code manually - update the footer template with the generated HTML of your own docs, make sure the search template can reach the scripts it needs (can be an issue mostly if you have cache busting enabled in your own repo). Also, update the index.md file to have the contents suitable for your case. Keep them updated if you change your own repo as well.
an MSBuild step in your content repo builds that will take the binaries, xml files and content repo, build the HTML files for the API ref, and copy them to the _site/api folder in your content repo.

This build is executed through the _buildApi/BuildApiReference.proj file. For example, in the VS command prompt: msbuild.exe BuildApiReference.proj /p:LatestBinariesPath=\\\\someNetworkServer\MySourceFiles;DocsRepoName=blazor-docs;DocumentationBaseUrl=https://docs.telerik.com/blazor-ui;DocsRepoApiAssetsFolder=_assetsApi;HasApiFilter=true

Here is a list of the build parameters and their purpose:
- LatestBinariesPath - the path to where you have the .dll+.xml pairs of code you want documented. The format is usually something like \\\\someNetworkServer\MySourceFiles or C:\work\myFolder. The escaping of the backslashes is an example for using this as a build parameter.
- DocsRepoName - the name of the repo with your actual contents. The build assumes the docs-seed repo and the content repo are in adjacent folders. So, it is, for example just blazor-docs or winforms-docs, or teststudio/docs (when the docs are nested further down in a folder inside your repo).
- DocumentationBaseUrl - the base URL of your docs when on the live server. Used for the sitemap.xml file. For example, https://docs.telerik.com/blazor-ui/.
- DocsRepoApiAssetsFolder - this is where the build assets specific to your repo reside (at the time of writing, search, footer templates, feedback form, plus a little of bit of styles). If you copy from an existing repo, this would always be _assetsApi.
- HasApiFilter - an optional parameter in case you want to avoid generating API reference docs for certain classes or their members. See the DocFx docs on the matter for syntax and examples. To use this filter, you must add a file in your repo with the desired filter contents, and put it in <DocsRepoApiAssetsFolder>\filterConfig.yml. The file is always at the root of the API assets folder, and is always called filterConfig.yml. Here's what docfx generate at the time of writing (10 Jul 2019, docfx version 2.40.5):
  
  C#
```
//GENERATED
public string publicTest;
protected string protectedTest;
protected internal string protectedInternalTest;

//NOT GENERATED
private string privateTest;
internal string internalTest;
private protected string privateProtectedTest;
```
