Slides presenter plugin

This is a plugin to show slides and code examples directly from IntelliJ IDEs.

Why?

It can be useful if large part of your presentation is based on code examples, so instead of copy-pasting code into Keynote or PowerPoint slides you can show both slides and code in IDE.

• Code examples stay up-to-date.
• You can run and modify code examples live to show how they work.
• Smooth transition between slides and code examples.

How to use?

1. Create slides.txt in IDE project with code examples.
2. Save presentation slides as images to some folder in IDE project folder (e.g. in Keynote in the main menu File -> Export To -> Images...). Note that ideally, images should be in the same resolution as the projector/screen you're going to present on (e.g. in Keynote click on Document in the main toolbar and choose Slide Size with custom slide size; note that Widescreen (16:9) corresponds to 1920×1080 px aka Full HD which seems to be the most common resolution at conferences at the moment). You can also change slides.presenter.zoom.factor in IDE Registry to scale slides, but unscaled images usually look better.
3. Edit slides.txt so that it contains paths to slides image files and code examples (see format description below). Note that you can use Save All action to make plugin reload slides.txt.
4. (Optional) use presentation mode View -> Enter Presentation Mode
5. Use Next Slide and Previous Slide actions. It's recommended to change default shortcuts to something more convenient (e.g. I use F12, F11; the only reason for defaults shortcuts alt-shift-F12, alt-shift-F11 is that they don't conflict with other actions).
6. Always check your presentation in advance on the actual setup.

Format of slides.txt

• Empty lines and lines starting with -- or # are ignored.
• Each line contains a path to a file with unix-style path separator / which can be an absolute path or path relative to the project root.
• Paths can include special syntax {{next N}} where N is the amount of times the line will be repeated with incremented counter. E.g. slides/slides.{{next 2}}.png will be expanded into two lines slides/slides.000.png and slides/slides.001.png.

For example:

# Some comment
/absolute/path/intro.png

-- More slides
slides/slides.{{next 2}}.png
src/code.js
src/more-code.js
slides/slides.{{next 2}}.png

For real-world example see slides.txt in coroutines-explained repository.

Implementation note

Admittedly, this plugin is just a hack. Please create/upvote issues if you have any problems.
