- **[blc_array](include/blc_array.h)** a structure to manage n-dimensional arrays. It also manage type and format of the data
- **[blc_realtime](include/blc_realtime.h)** few helpers to use time, POSIX semaphore and pthreads
However, independently of blaar, you can [manually build the library](
\ No newline at end of file
This library is installed with any configuration of blaar. However, independently of blaar, you can [manually build the library](
Exemple of simple text functions
#include "blc_core.h"
int main(int argc, char **argv){
int rows_nb, columns_nb;
float values[3]={1.3, 4.2, 5.5};
color_printf(BLC_BLUE, "\nWriting in blue\n\n");
underline_printf('=', "Writing with inlining with '='");
//printing 3 floats of the array values
fprint_tsv_floats(stderr, values, 3);
//Getting the size in characters of the current terminal
blc_terminal_get_size(&columns_nb, &rows_nb);
printf("\nSize of the terminal %dx%d\n", columns_nb, rows_nb);
//Writing size in human readable format
fprint_human_size(stdout, 1000456670); //1Kb = 1024b
Exemple of text graphs
This is the output of **blc_core/t_array** see the [code]( and the [cmake config file](
### Manipulating **blc_array** vector
You can modify the code to dynamically refresh the graph with something like:
//We display 100 times the graph with the sinusoid shifted each time
for(shift =0; shift <100; shift ++){
// We set a sinusoid in the vector (converting [-1f, 1f] -> [0, 255]) and we shift it
for(i=0; i!=vector.size; i++) vector.uchars[i]=128+127*sinf(i/2.f+ shift);
//If it is not the first time we erase the previous graph by putting back (ANSI escape code) the cursor 16 lines (height of the graph) up. 'sprint' stand for fprint on stderr
if (shift != 0) blc_eprint_cursor_up(16); //blc_text.h function
/*We graph the vector, with title "vector test", the height of 16 chars, the limit max 256 and limit min 0.
Text on abscissa "position" and text on ordinate "intensity"*/
vector.fprint_graph_uchars(stderr, "Vector test", 16, 256, 0, "position", "intensity");
//We stop 100ms to let time to the user to see the graph.

These displays could be dynamical as well
