All 17 page scripts (i18n, shared helpers, navigation and the per-page
scripts) are merged into one html/main.js that every page loads as its
only script, so the browser fetches it once and gzip can compress
across all of it.
The page-specific initialisation is guarded by the presence of the
matching page elements (it used to be selected implicitly by which
script a page loaded); the sidebar fill and the stat popup wiring moved
into DOMContentLoaded handlers because the bundle loads in <head>,
before the body exists.
tools/httpd_sim.h: BUFFER_SIZE 24000 -> 131072 so the simulator can
serve the larger bundle (the firmware is unaffected, it serves the
gzip'd bundle of ~17 KB).
Measured (make MACHINE=KP_9000_6XHML_X2): the JS drops from 23,302 to
16,948 bytes gzip; the whole Web UI from 34,784 to 28,200 bytes (25.3 %
of the raw 111,280); the data block ends at 0x46e28. Verified with a
headless browser against httpd_sim and against a real PCB-K0402WS-V3:
all pages render, the sidebar and the port strip are drawn, no
JavaScript errors.
Two build-time steps shrink the embedded Web UI (html/) from 113,015 to
34,784 bytes (30.8 %):
- tools/minify.py (new): string-literal-safe minifier that strips
comments and indentation; comments are pure overhead on the wire, so
the transfer size drops already before gzip (113,015 -> 101,498).
Binary files (.ico) are copied through unchanged. The output goes to
output/html_min/, the new fileadder input.
- fileadder -z: gzip-compresses every added file (zlib gzip format,
Z_BEST_COMPRESSION); the generated f_data entries carry a gzip flag.
tools/Makefile links the tool against -lz.
- httpd: adds "Content-Encoding: gzip" for flagged entries; the 8051
only copies compressed bytes, decompression happens in the browser.
The JSON API stays uncompressed.
Fixes required to make the sizes deterministic:
- fileadder terminated files at data_read + 1, so the strlen()-based
size computation depended on uninitialised buffer content; the NUL
now lands directly after the content.
- version.h was .PHONY, so every build rewrote it while parallel builds
could read a half-written copy.
- the file list was unscoped and missed .css/.ico; it is now scoped to
html/ and covers all embedded types.
Measured with make MACHINE=KP_9000_6XHML_X2: data block end moves from
0x5b977 to 0x487e0 (~78 KB freed on a 512 KB image). Verified with
MACHINE=PCB_K0402WS_V3 and on real hardware (PCB-K0402WS-V3).
Add a language selector to the System Settings page supporting English,
Japanese, and Chinese. The i18n dictionary already contained zh
translations but lacked the UI to switch languages.
Changes:
- html/i18n.js: add sys_language key to en/ja/zh
- html/system.html: add language selector dropdown
- html/system.js: add changeLang() and selector initialization
- tools/httpd_sim.c: fix cookie parsing for multi-cookie headers;
fix Set-Cookie response (missing Path=/, missing \r\n\r\n);
add SO_REUSEADDR for faster port reuse
