 1 | # keyboard-tester, for linux & macOS
 2 | 
 3 | Written so I could test macbook keyboards before sending back to clients after a board repair or similar service.
 4 | 
 5 | Works on keyboard scancodes, not keycodes, so will work with all keyboards but you'll be left with varying levels of keys that aren't "pressed".
 6 | 
 7 | #### BETA DEVELOPMENT --- Seems to be okay to use now
 8 | 
 9 | ### Prerequisites
10 | 
11 | Requires SDL2 and SDL2_ttf
12 | 
13 | linux
14 | ```
15 | apt install libsdl2-dev
16 | ```
17 | 
18 | macOS
19 | ```
20 | brew install libsdl2 libsd2_ttf
21 | ```
22 | 
23 | ### Build
24 | ```make```
25 | 
26 | ### Parameters
27 | ```
28 | keyboard-tester [--dl <lower bound ms>] [--dh <upper bound ms>] [-m <mapfile>] [-c] [--dpi <dpi>] [--fs <pts>] [-d]
29 | 
30 | --dl <time (20 ms default)> : Set acceptable lower limit of key down time
31 | --dh <time (200 ms default)> : Set acceptable upper limit of key down time
32 | -m <mapfile> : Set keyboard map to use, limits keys and sets names to test
33 | -c : Close tester when all keys have been pressed
34 | 
35 | --kwidth <px> : Width of key in pixels
36 | --kheight <px> : Height of key in pixels
37 | --kspacing <px> : Gap between keys in pixels
38 | --columns <n> : How many columns of keys to show
39 | --compact : Remove null/empty keys from grid display
40 | 
41 | --colbg <rrggbb> : background
42 | --colkey <rrggbb> : key block
43 | --coltext <rrggbb> : key text
44 | --colpressed <rrggbb> : key block colour while pressed
45 | --colreport <rrggbb> : after-pressed report text (normal)
46 | --colflagged <rrggbb> : after-pressed report text (flagged)
47 | 
48 | --dpi <dpi> : Force screen DPI
49 | --fs <pts> : Set font size in pts
50 | --fscale : Scale the key text rather than cropping
51 | 
52 | -d : Enable debugging output
53 | 
54 |         ALT/OPT-Q: exit/quit
55 |         ALT/OPT-M: Save current pressed keyset to mapfile
56 | ```
57 | 
58 | ### Application Controls
59 | ```
60 | 	alt-q / opt-q : quit
61 | 	alt-m / opt-m : Save currently pressed keys array to map file
62 | ```
