# kprintf
|
|
It is just my variant of printf.
|
|
|
|
# kprint
|
|
I don't really like printf function (and its variants), so i made safer and more convinient replacement.
|
|
|
|
| function | returns | arguments |
|
|
|----------|---------|-----------|
|
|
| kprint | void/throw | kprint_format, void*, kprint_format, void*... |
|
|
| ksprint | Maybe<char*> | kprint_format, void*, kprint_format, void*... |
|
|
| kfprint | Maybe<void> | FILE*, kprint_format, void*, kprint_format, void*... |
|
|
|
|
## how to use it:
|
|
+ **format construction:**
|
|
```
|
|
kprint_format fmt= kprint_fgColor | kprint_bgColor | kprint_fdataFmt | flags | ktid;
|
|
```
|
|
[more about `kprint_format`](kprint_format.md)
|
|
+ fgColor and bgColor can be set to change console output color
|
|
+ you should set dataFormat for `int`/`uint`/`float`/`char*` arguments and ktid for other types
|
|
+ flags can be set to modify TypeDescriptor.toString() behavior
|
|
+ don't forget to set TypeDescriptor.toString when registering type, or kprint will crash
|
|
|
|
+ **using base type arguments:**
|
|
you can just put them into a function
|
|
```
|
|
kprint(kprint_fmtHex | kprint_fmtUppercase | kprint_fmtWithPrefix, 255);
|
|
```
|
|
output: 0xFF
|
|
+ **using other registered types:**
|
|
should be sent as pointers
|
|
```
|
|
Maybe m=MaybeNull;
|
|
kprint(kprint_fgBlue | kprint_fmtString, "Maybe: ", kprint_fgGreen | ktid_MaybePtr, &m);
|
|
```
|
|
output: <span style="color:blue">Maybe:</span> <span style="color:lightgreen">{value={0, ktid_Null}}</span> |
