A minimalist major mode for Processing 3, leveraging the p3 command line tools. It provides convenient access to compiler features and some basic development niceties, such as p3-aware keyword font locking.
The mode requires Processing 3 with CLI tools enabled. For more information on those, read the official documentation.
Until the package is published on melpa, I recommend using straight.el.
If you want p3-mode to automatically start when opening .pde files,
add the following snippet to your init file.
(add-to-list 'auto-mode-alist '("\\.pde$" . p3-mode))You can enable any of the flags supported by processing-java.
| Flag | Values |
|---|---|
processing-3-no-java |
nil (default), t |
processing-3-force |
nil (default), t |
processing-3-platform |
nil (default), 'linux, 'macosx, 'windows |
processing-3-compile-key |
'run (default), 'build, 'present, 'export |
processing-3-args |
"" (default), any string |
processing-3-args is a string used to add command-line arguments when calling processing-java.
As this is most likely file-dependent, it can be useful to add these using buffer local variables.
Below is an example using the block quote syntax.
/* Local Variables: */
/* mode: processing-3 */
/* processing-3-args: "300 400" */
/* End: */
void setup() {
// etcThe following keybindings are provided out of the box.
| Function | Keymap |
|---|---|
| run | C-c C-r |
| build | C-c C-b |
| present | C-c C-p |
| export | C-c C-e |
| compile-cmd | C-c C-c |
compile-cmd (C-c C-c) is meant as a convenience bind to whatever build function you use the most.
It is controlled by processing-3-compile-cmd and defaults to 'run.
processeing-mode comparability, if that would be of use to anyone, open an issue!).
