Espruino Documentation and Code
PLEASE VIEW THIS DOCUMENTATION ON WWW.ESPRUINO.COM - you can even Search. The markdown files in this repository are designed to be parsed by a build script - by viewing them on GitHub you may be missing useful links or information.
This project generates the website and tutorial code for Espruino.com. This also contains the modules that can be required by the Espruino Web IDE. You can contribute to the site and modules in this project.

Documentation files are written GitHub Markdown with additional metadata. Basically, a script that looks for the following (on the start of a line):
* KEYWORDS: Comma,Separated,List ; Defines keywords for this file
* APPEND_KEYWORD: Keyword ; Append a list of pages that match the keyword
* USES: Comma,Separated,List ; Defines parts that are used by the given tutorial
* APPEND_USES: part ; Append a list of pages that have this part in their USES_PARTS list
* APPEND_JSDOC: filename ; Append JavaScript documentation based on the JS in the given file
* APPEND_PINOUT: boardname ; Append Pinout for the given board
* BUYFROM: normalprice,bulkprice,link1,link2|optional_name,link3 ; Append a floating 'buy from' window
* APPEND_TOC ; Append a table of contents made from H1/H2/H3 (and add them as keywords)
* LIST_LINKS_AS_KEYWORDS ; Add lists of links `* [...](...)` as keywords
It also looks for a title (second line, after copyright notices) which it uses to create the title of the HTML page (and of links to it).
There are a few extra bits too:
[[My Page]]links to a page on the Espruino website[[http://youtu.be/VIDEOID]]puts a video on the pageAdds an image. Images should be in a directory named after the filename of the file referencing them (or the same directory as the file referencing them)- The first image in the file (or a file named
PageName.thumb.jpg/png) is resized and used as the thumbnail. If there's no image on the page at all it's added top-right.
It then converts the Markdown to HTML and shoves it on the Espruino website. Lovely!
JavaScript
Any .js files in examples have a webpage created that uses the comments as markdown, and then adds the code as a code block right at the end.
All other .js files are treated as modules. They are minified using Google's online closure compiler and the SIMPLE_OPTIMISATIONS flag. To get advanced optimisations, you must add the exact text @compilation_level ADVANCED_OPTIMIZATIONS into the comments at the head of the file.

Build Requirements
Step 1: Obtain Espruino Source Code & Web Tools
Check out the Espruino and EspruinoWebTools repositories at the same same level as EspruinoDocs folder. Assuming you're in the EspruinoDocs folder...
$ cd ..
$ git clone [email protected]:espruino/Espruino.git`
$ git clone [email protected]:espruino/EspruinoWebTools.git
$ cd EspruinoDocs
Step 2: Install Node.js® and npm
If you have Node.js and npm installed skip this step.
If you haven't got Node.js JavaScript runtime installed or the JavaScript Package managers installed do so via the installation guides below.
On Linux, you may have nodejs and not node in your path. This will lead to issues later on in the build process. This problem is easily solved by running sudo ln -s /usr/bin/nodejs /usr/bin/node which will create a symbolic link, so you can use both node and nodejs at the terminal.
Step 3: Install Required Node Modules
In order to generate the documentation and view it you require several JavaScript packages. To install them issue the following command:
$ npm install
This will install all JavaScript dependencies.
Build Process
Currently they are two build scripts. One bash, one JavaScript.
The bash script does 3 things:
- Uses the
Espruinosource code to generate the pinout diagrams.pythonis required - Builds the production site at
~/workspace/espruinowebsite - Builds Espruino specific modules and minifies the JavaScript code
The JavaScript build process just builds the documentation in the html folder.
You will have to run build.sh at least once if you want the build.js to work.
To Do a Full Build
Run:
$ ./build.sh
To Build Documentation Only
Note: You've had to have least ran the bash script once for this to build successfully.
Run:
$ npm run build
The output will be placed in the html directory.
View Generated Documentation
You can load a development version of the website locally. It will not look exactly like the production site but you can test your build and links.
$ npm start
Then load up a page in a browser: http://localhost:3040/Original
Troubleshooting
OS X
Set Maximum Open Files
On OSX, most likely the default amount of open files will be set too low. This may cause an error during the build, like: "Error: EMFILE, too many open files 'tasks/File Converter.md'"
Make sure you have at least 1024 for the value of open files.
$ ulimit -n # see current limit
Increase the limit:
$ ulimit -n 1024 # increase to 1024
Linting
You can lint modules using:
# Install required tools
npm install eslint
# Lint all js files in devices folder
npm run eslintdevices
# Lint all js files in modules folder
npm run eslintmodules
# Lint all js files in boards folder
npm run eslintboards
