Conky: Feature request "Auto line break for long text"

[Microcrap]

Hello everybody.
Would it be possible to add a parameter allowing the automatic addition of line break when one or more lines of text exceed the container, as with HTML ?

I am not certain, but we might have this before without the config. <= v1.11.4 or so.

For people who do not want to w8t, how to add auto line break in bash :

word1='Cette phrase est longue.'
word2=' Dieser Satz ist lang.'
word3=' This sentence is long.'
echo "${word1}${word2}${word3}" | fmt --width=20

Adapt --width=20 to your line lenght

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>

int main(void) {
  char str[] = "20 Cette phrase est longue. Dieser Satz ist lang. This sentence is long.";
  char *old_ptr = str;
  char buf[200];
  char *buf_ptr = buf;
  char num[50];
  char *nums = num;
  unsigned int x = 0;
  unsigned int z = 1;

  for (; *old_ptr; old_ptr++) {
    if (!isdigit((unsigned char)*old_ptr)) {
      break;
    }
    *nums++ = *old_ptr;
  }
  *nums = '\0';

  old_ptr++;
  x = (unsigned int)strtoul(num, (char **)NULL, 10);

  for (; *old_ptr; old_ptr++, z++) {
    if (x == z) {
      z = 1U;
      *buf_ptr++ = '\n';
    }
    *buf_ptr++ = *old_ptr;
  }
  *buf_ptr++ = '\0';

  printf("%s\n",buf);

  return EXIT_SUCCESS;
}

My computer broke and I wrote this code on my tablet. Such code with malloc can be added to conky too.

This goes in common.h

void print_fold(struct text_object *, char *, unsigned int);

this goes in common.c

void print_fold(struct text_object *obj, char *p, unsigned int p_max_size) {
  char *old_ptr = obj->data.s;
  char *buf;
  char *buf_ptr = buf;
  char num[50];
  char *nums = num;
  unsigned int x = 0;
  unsigned int z = 1;

  evaluate(obj->data.s, p, p_max_size);
  if (0 != (strcmp(p, ""))) {
    old_ptr = p;
  }

  for (; *old_ptr; old_ptr++) {
    if (!isdigit((unsigned char)*old_ptr)) {
      break;
    }
    *nums++ = *old_ptr;
  }
  *nums = '\0';

  if (*old_ptr) {
    old_ptr++;
  } else {
    return;
  }

  x = (unsigned int)strtoul(num, (char **)NULL, 10);

  buf = (char *)malloc(p_max_size * 2);
  if (!buf) {
    return;
  }

  for (; *old_ptr; old_ptr++, z++) {
    if (x == z) {
      z = 1U;
      *buf_ptr++ = '\n';
    }
    *buf_ptr++ = *old_ptr;
  }
  *buf_ptr++ = '\0';

  snprintf(p, p_max_size, "%s", buf);
  free(buf);
}

and this goes in core.c

  END OBJ(fold, nullptr) obj->data.s = STRNDUP_ARG;
  obj->callbacks.print = &print_fold;
  obj->callbacks.free = &gen_free_opaque;

Note that I don't have a computer and i leave all the testing up to you.

Test it with static text and one with variables in it.

My computer broke

Huh. More than a year ago...

I lost 75 lbs since 6 months ago. Still want to lose more. I'm a gym rat now. Currently injured tho.

Anyway, welcome back, @su8! We need to get you a computer. :wink:

Just ran git bisect. We never had this. I think I recall textwrap behavior in journal (https://github.com/brndnmtthws/conky/issues/565).
