+# c-ansi-sequences
+The ANSI escape sequences used for terminal display control wrapped in macros. Everything is very simple, you can pretty much understand what each macro does when looking at the `#define`s and comments. If you are intierested enough into this and want more documentation, open an issue and hope it'll reach me.
+
+## Examples
+```c
+#include <stdio.h>
+#include <c-ansi-sequences/graphics.h>
+
+int main(void)
+{
+  printf(ANSIQ_SETFG_GREEN"Hello, world!"ANSIQ_GR_RESET"\n");
+  return 0;
+}
+```
+The code above will print `Hello, world!`in green text color. If you want to compose more styles together, do this:
+```c
+printf(ANSIQ_GR_SEQ(ANSIQ_FG_WHITE ANSIQ_BG_BLUE
+                      ANSIQ_TXT_BLD ANSIQ_TXT_ITL)
+       "White, bold, italic text on blue background"ANSIQ_GR_RESET"\n");
+```
+If you want to use the same style composition in multiple places, you csn wrap that in a macro:
+```c
+#define WARNING(text)                               \
+  ANSIQ_GR_SEQ(ANSIQ_FG_YELLOW ANSIQ_TXT_UNL) \
+  text ANSIQ_GR_RESET
+  printf(WARNING("This is a warning")"\n");
+```
