index.html now contains all pages as sections (overview, ports, stat, vlan, l2, mirror, lag, eee, bandwidth, system, update); the sidebar switches between them via the URL hash (#/ports, #/vlan, ...). login.html stays separate as the authentication gate. A section's initialisation runs when the section is shown, its polling intervals run only while it is visible, and re-entering a section refetches the data; the checkbox builders (lag/vlan/mirror) and the L2 scanner were made idempotent so re-initialising cannot duplicate rows. tools/minify.py: recognise regex literals - an escaped slash before the closing delimiter was previously stripped as a // comment. Measured (make MACHINE=KP_9000_6XHML_X2): 8 embedded files, 109,814 -> 97,730 -> 25,302 bytes gzip (23.0 %); the data block ends at 0x462d6 (~86 KB freed). On a real PCB-K0402WS-V3: cold load ~450 ms, section switches ~60-160 ms with no asset re-downloads, all sections render without JavaScript errors.

"""Safe minifier for the WebUI sources (HTML/JS).
|
|
|
|
Removes comments and line-leading whitespace without touching string or
|
|
regex literals, so the output is functionally identical to the input.
|
|
Used by the firmware Makefile before the files are embedded in the
|
|
flash; the raw sources in html/ stay untouched for development.
|
|
|
|
Binary files (.ico) are copied through unchanged.
|
|
|
|
Usage: minify.py <src> <dst>
