Code demonstrating problem
voidsetup() { Serial.begin(9600);while (!Serial) {}// this code should remove all occurrences of "narf" from the string String s ="narf"; Serial.println(); Serial.print("input: ("); Serial.print(s); Serial.println(")"); s.replace("narf",""); Serial.print("result: ("); Serial.print(s); Serial.println(")"); s ="narf narf"; Serial.println(); Serial.print("input: ("); Serial.print(s); Serial.println(")"); s.replace("narf",""); Serial.print("result: ("); Serial.print(s); Serial.println(")");}voidloop() {}
Serial monitor output:
input: (narf)result: ()input: (narf narf)result: (narf narf)Additional information
In this code:
while ((foundAt = strstr(readFrom, find.buffer)) !=NULL) {readFrom = foundAt + find.len;diff =0 - diff;size -= diff;}
line 669 (diff = 0 - diff;) should be above thewhile loop.
