1 | # Secret Macros | ||
2 | |||
3 | With help from gitter and Colinta, this adds the ability to add hidden macros from other users. | ||
4 | |||
5 | First, I have several files that are hidden/excluded from Git/GitHub. These contain everything needed for the macros. To hide these files, open `.git/info/exclude` and add `secrets.c` and `secrets.h` to that file, below the comments. | ||
6 | |||
7 | And this requires `KC_SECRET_1` through `KC_SECRET_5` to be added in your keycode enum (usually in your `<name>.h` file) the keycodes for the new macros. | ||
8 | |||
9 | ## Git Exclusion | ||
10 | |||
11 | To prevent `git` from seeing, or committing the secret files, you can exclude them. What's the point of having secrets if they're posted on GitHub for everyone to see!?! | ||
12 | |||
13 | You can do this with the `.git/info/exclude` file, so that it's only ignored locally. Unfortunately, that means it's not consistently handled on each system. | ||
14 | |||
15 | However, if you create a `.gitignore` file in the same folder, you keep things consistent between every system that the code is checked out on. | ||
16 | |||
17 | ```c | ||
18 | secrets.c | ||
19 | secrets.h | ||
20 | ``` | ||
21 | |||
22 | ## secrets.c | ||
23 | |||
24 | Here is the magic. This handles including the "secrets", and adding the custom macros to send them. | ||
25 | |||
26 | ```c | ||
27 | #include "drashna.h" // replace with your keymap's "h" file, or whatever file stores the keycodes | ||
28 | |||
29 | #if (__has_include("secrets.h") && !defined(NO_SECRETS)) | ||
30 | #include "secrets.h" | ||
31 | #else | ||
32 | // `PROGMEM const char secret[][x]` may work better, but it takes up more space in the firmware | ||
33 | // And I'm not familiar enough to know which is better or why... | ||
34 | static const char * const secret[] = { | ||
35 | "test1", | ||
36 | "test2", | ||
37 | "test3", | ||
38 | "test4", | ||
39 | "test5" | ||
40 | }; | ||
41 | #endif | ||
42 | |||
43 | bool process_record_secrets(uint16_t keycode, keyrecord_t *record) { | ||
44 | switch (keycode) { | ||
45 | case KC_SECRET_1 ... KC_SECRET_5: // Secrets! Externally defined strings, not stored in repo | ||
46 | if (!record->event.pressed) { | ||
47 | clear_oneshot_layer_state(ONESHOT_OTHER_KEY_PRESSED); | ||
48 | send_string_with_delay(secret[keycode - KC_SECRET_1], MACRO_TIMER); | ||
49 | } | ||
50 | return false; | ||
51 | break; | ||
52 | } | ||
53 | return true; | ||
54 | } | ||
55 | ``` | ||
56 | |||
57 | ## secrets.h | ||
58 | |||
59 | Now, for the actual secrets! The file needs to look like | ||
60 | |||
61 | ```c | ||
62 | static const char * secrets[] = { | ||
63 | "secret1", | ||
64 | "secret2", | ||
65 | "secret3", | ||
66 | "secret4", | ||
67 | "secret5" | ||
68 | }; | ||
69 | ``` | ||
70 | |||
71 | Replacing the strings with the codes that you need. | ||
72 | |||
73 | ## Process Record | ||
74 | |||
75 | In whichever file you have your `process_record_*` function in, you will want to add this to the top: | ||
76 | |||
77 | ```c | ||
78 | __attribute__ ((weak)) | ||
79 | bool process_record_secrets(uint16_t keycode, keyrecord_t *record) { | ||
80 | return true; | ||
81 | } | ||
82 | ``` | ||
83 | |||
84 | This is so that the function can be called here, and replaced in the `secrets.c` file, and so it won't error out if it doesn't exist. | ||
85 | |||
86 | And then, in the `process_record_user` function, assuming you have `return process_record_keymap(keycode, record)` here, you'll want to replace the "final" return with the following. Otherwise, you want to replace the `return true;` with `return process_record_secrets(keycode, record);` | ||
87 | |||
88 | ```c | ||
89 | bool process_record_user(uint16_t keycode, keyrecord_t *record) { | ||
90 | // your existing macro code here. | ||
91 | return process_record_keymap(keycode, record) && process_record_secrets(keycode, record); | ||
92 | } | ||
93 | ``` | ||
94 | |||
95 | ## rules.mk | ||
96 | |||
97 | Here, you want your `/users/<name>/rules.mk` file to "detect" the existence of the `secrets.c` file, and only add it if the file exists. | ||
98 | |||
99 | Additionally, to ensure that it's not added or processed in any way, it checks to see if `NO_SECRETS` is set. This way, if you run `make keyboard:name NO_SECRETS=yes`, it will remove the feature altogether. | ||
100 | |||
101 | ```make | ||
102 | ifneq ($(strip $(NO_SECRETS)), yes) | ||
103 | ifneq ("$(wildcard $(USER_PATH)/secrets.c)","") | ||
104 | SRC += secrets.c | ||
105 | endif | ||
106 | endif | ||
107 | ``` | ||
108 | |||
109 | Alternately, if you want to make sure that you can disable the function without messing with the file, you need to add this to your `/users/<name>/rules.mk`, so that it catches the flag: | ||
110 | |||
111 | ```make | ||
112 | ifneq ("$(wildcard $(USER_PATH)/secrets.c)","") | ||
113 | SRC += secrets.c | ||
114 | endif | ||
115 | |||
116 | ifeq ($(strip $(NO_SECRETS)), yes) | ||
117 | OPT_DEFS += -DNO_SECRETS | ||
118 | endif | ||
119 | ``` | ||
120 | |||
121 | ## Extras | ||
122 | |||
123 | Additionally, because this file isn't present in the repo at all, you could add additional functionality that nobody else will see. | ||
