### Editor Configuration

- You can import it within eclipse settings, `Preferences -> LANGUAGE -> Code Style -> Formatter` tab.
## Logging and Debugging Messages
The logging system is designed to make log messages clearer and improve their uniformity across the project.
It makes it easier to see where a log message comes from and what its verbosity is.
## Commit Messages Conventions
The subject line of a commit message should follow the following rules:
- Short and descriptive (max 50 chars)
- In imperative present tense
- Capitalized
- Not end with a period
To use the logging system, include `log.h` in your source file, and use the following macros to print log messages:
```c
LOG_DEBUG(TAG, fmt, ...)
LOG_INFO(TAG, fmt, ...)
LOG_WARN(TAG, fmt, ...)
LOG_CRIT(TAG, fmt, ...)
LOG_FATAL(TAG, fmt, ...)
Example:
```
The same format specifiers as in `printf` can be used.
The `TAG` parameter is a string that identifies the source of the log message.
It is recommended to use one tag for each source file / module, and to name the tag after the source file / module.
See the example below.
### Global Log Level
You can control the verbosity of the logging output by setting a global log level in `log.h`.
This log level filters out messages with a lower priority.
### Custom Log Levels
before you include `log.h`, you can define custom log levels by defining the following macros:
```c
// All log messages will be printed
#define LOGGER_LEVEL_ALL
#include "log.h"
Implement access right management
```
```c
// Info and higher priority messages will be printed
#define LOGGER_LEVEL_INFO
#include "log.h"
```
The body of a commit message may be used to explain the what and why of a commit.
```c
// Only warnings and errors will be printed
#define LOGGER_LEVEL_WARN
#include "log.h"
```
## Documentation
Documentation is placed in the [docs](docs) folder.
If your part needs documentation (e.g. how to use tcp cmd interface), add a markdown file in the above-mentioned folder.
```c
// Only log messages with level ERROR will be printed
#define LOGGER_LEVEL_CRITICAL
#include "log.h"
```
```c
// Only log messages with level ERROR will be printed
#define LOGGER_LEVEL_FATAL
#include "log.h"
```
### Colorful Log Messages
For improved readability, log messages can be printed in color by defining `LOGGER_USE_COLOR` in `log.h` or before you include `log.h`. \
Default is `0`
### Log Output Format
Each log entry is formatted to include the following information:
- Log level ([Debug], [Info], [Warn], [Critical], [Fatal])
- Timestamp (in milliseconds since boot)
- Tag
- The log message
For instance, a log entry may look like this:
`[Info] (2009) [LTDC]: This is a log message`
### Example
```c
#define LOGGER_LEVEL_INFO
#include "log.h"
// Don't use a define for the tag, as the pointer to the tag is used
static const char *TAG = "main";
int main(void) {
LOG_DEBUG(TAG, "This message will not be printed");
LOG_INFO(TAG, "This message will be printed");
LOG_WARN(TAG, "This message will be printed");
LOG_CRIT(TAG, "This message will be printed");
LOG_FATAL(TAG, "This message will be printed");
for (int i = 0; i < 3; i++) {
LOG_INFO(TAG, "Iteration %d of %d", i, 3);
}
return 0;
}
```
Result:
```
[Info] (2009) main: This message will be printed
[Warning] (2026) main: This message will be printed
[CRITICAL] (2033) main: This message will be printed
[FATAL] (2040) main: This message will be printed
[Info] (2040) main: Iteration 0 of 3
[Info] (2047) main: Iteration 1 of 3
[Info] (2054) main: Iteration 2 of 3

# LLFS (Linked List File System)
## Introduction
The llfs filesystem can be generated using the mkllfss utility.
It is a simple filesystem that uses a linked list to store files.
The filesystem is stored in a single c file (`llfs_data.c`), which can be compiled and read by the llfs library.
The llfs filesystem is a flat filesystem, meaning that it does not support directories.
## Usage of the llfs API
### Getting a list of files
```c
#include "llfs.h"
void main(void) {
// Allocate space for 10 files
llfs_file_t file_list[10];
// Get the file list
size_t file_count = llfs_file_list(file_list, 10, NULL);
// Loop through the files and print their names and sizes
for (int i = 0; i < file_count; i++) {
LOG_INFO(TAG, "File: %s, size: %d", file_list[i].name, file_list[i].len);
}
}
```
Result:
```
[Info] (2009) [main]: File: image.bmp, size: 9270
[Info] (2013) [main]: File: python_file.py, size: 645
[Info] (2019) [main]: File: image2.bmp, size: 7738
[Info] (2024) [main]: File: filename with a space.txt, size: 61
[Info] (2031) [main]: File: file1.txt, size: 77
```
### Reading a file
```c
#include "llfs.h"
void main(void) {
// Get a file by name
llfs_file_t *file = llfs_file_open("filename with a space.txt");
if (file != NULL) {
// Print the file name, size and data
LOG_INFO(TAG, "File found: %s, size: %d", file->name, file->len);
LOG_INFO(TAG, "File data: %s", file->data);
} else {
LOG_WARN(TAG, "File not found");
}
}
```
Result:
```
[Info] (2040) [main]: File found: filename with a space.txt, size: 61
[Info] (2047) [main]: File data: This is a file with a space in it's filename.

# MKLLFS (Make Linked List File System)
## Introduction
The llfs filesystem can be generated using the mkllfss utility. It is a simple filesystem that uses a linked list to store files.
The filesystem is stored in a single c file (llfs_data.c), which can be compiled and read by the llfs library.
The llfs filesystem is a flat filesystem, meaning that it does not support directories.
The mkllfs utilit can be used to generate the `llfs_data.c` file. The `llfs_data.c` file from a directory with files.
## Usage
The mkllfs utility can be used as follows:
```bash
mkllfs [options] <directory> <output_file>
```
For example:
```bash
mkllfs data llfs_data.c
```
Available options:
```
-h, --help show the help message and exit
-v, --version print the version of mkllfs and the llfs library that it generates for
```
## Building
The mkllfs utility can be built using the following command:
```bash
gcc -o mkllfs mkllfs.c
```
For windows, you can use the following command:
```bash
gcc -o mkllfs.exe mkllfs.c
```
