# INI parser library
|
||||
|
||||
This is a very simple ini-parser library that provides:
|
||||
- Raw record reading
|
||||
- Leading/trailing whitespace removal
|
||||
- comments based on `;` and `#`
|
||||
- Zig API
|
||||
- C API
|
||||
|
||||
## Usage example
|
||||
|
||||
### Zig
|
||||
|
||||
```zig
|
||||
const std = @import("std");
|
||||
const ini = @import("ini");
|
||||
|
||||
pub fn main() !void {
|
||||
const file = try std.fs.cwd().openFile("example.ini", .{});
|
||||
defer file.close();
|
||||
|
||||
var parser = ini.parse(std.testing.allocator, file.reader());
|
||||
defer parser.deinit();
|
||||
|
||||
var writer = std.io.getStdOut().writer();
|
||||
|
||||
while (try parser.next()) |record| {
|
||||
switch (record) {
|
||||
.section => |heading| try writer.print("[{s}]\n", .{heading}),
|
||||
.property => |kv| try writer.print("{s} = {s}\n", .{ kv.key, kv.value }),
|
||||
.enumeration => |value| try writer.print("{s}\n", .{value}),
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### C
|
||||
|
||||
```c
|
||||
#include <ini.h>
|
||||
|
||||
#include <stdio.h>
|
||||
#include <stdbool.h>
|
||||

|
||||

|
||||

||||

|
||||
while(true)
|
||||
{
|
||||

||||

# Tiny TTF font engine
|
||||
|
||||
## Usage
|
||||
|
||||
Use https://github.com/nothings/stb to render TrueType fonts in LVGL.
|
||||
|
||||
When enabled in `lv_conf.h` with `LV_USE_TINY_TTF`
|
||||
`lv_tiny_ttf_create_data(data, data_size, font_size)` can be used to
|
||||
create a TTF font instance at the specified font size. You can then
|
||||
use that font anywhere `lv_font_t` is accepted.
|
||||
|
||||
By default, the TTF or OTF file must be embedded as an array, either in
|
||||
a header, or loaded into RAM in order to function.
|
||||
|
||||
However, if `LV_TINY_TTF_FILE_SUPPORT` is enabled,
|
||||
`lv_tiny_ttf_create_file(path, font_size)` will also be available,
|
||||
allowing tiny_ttf to stream from a file. The file must remain open the
|
||||
entire time the font is being used, and streaming on demand may be
|
||||
considerably slower.
|
||||
|
||||
After a font is created, you can change the font size in pixels by using
|
||||
`lv_tiny_ttf_set_size(font, font_size)`.
|
||||
|
||||
By default, a font will use up to 4KB of cache to speed up rendering
|
||||
glyphs. This maximum can be changed by using
|
||||
`lv_tiny_ttf_create_data_ex(data, data_size, font_size, cache_size)`
|
||||
or `lv_tiny_ttf_create_file_ex(path, font_size, cache_size)` (when
|
||||
available). The cache size is indicated in bytes.
|
||||
|
||||
## API
|
||||
|
||||
```eval_rst
|
||||
.. doxygenfile:: lv_tiny_ttf.h
|
||||
:project: lvgl
|
||||
```
