If you have just a pair of brackets ( [] ) in your string, you can use indexOf(): String str = “ABC[ This is the text to be extracted ]”; String result = str.substring(str.indexOf(“[“) + 1, str.indexOf(“]”));
From the MDC doc center: Note: When the string is empty, split returns an array containing one empty string, rather than an empty array. Read the full docs here: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/split In other words, this is by design, and not an error 🙂
The latest builds of FFMPEG include a new option “segment” which does exactly what I think you need. ffmpeg -i INPUT.mp4 -acodec copy -f segment -vcodec copy -reset_timestamps 1 -map 0 OUTPUT%d.mp4 This produces a series of numbered output files which are split into segments based on Key Frames. In my own testing, it’s worked …

You could add a filter to exclude the empty string. var string = ‘a,b,c,d,e:10.’; var array = string.split (‘.’).filter(function(el) {return el.length != 0});
import re s=”abcd2343 abw34324 abc3243-23A” re.split(‘(\d+)’,s) > [‘abcd’, ‘2343’, ‘ abw’, ‘34324’, ‘ abc’, ‘3243’, ‘-‘, ’23’, ‘A’] Or, if you want to split on the first occurrence of a digit: re.findall(‘\d*\D+’,s) > [‘abcd’, ‘2343 abw’, ‘34324 abc’, ‘3243-‘, ’23A’] \d+ matches 1-or-more digits. \d*\D+ matches 0-or-more digits followed by 1-or-more non-digits. \d+|\D+ matches 1-or-more …
The following command will change a vertical split into a horizontal split: ctrl+w then J To change back to a vertical split use either: ctrl+w H or ctrl+w L For more information about moving windows: :h window-moving :h ctrl-w_J :h ctrl-w_K :h ctrl-w_H :h ctrl-w_L
There is apex_util.string_to_table – see my answer to this question. Also, prior to the existence of the above function, I once posted a solution here on my blog. Update In later versions of APEX, apex_util.string_to_table is deprecated, and a similar function apex_string.split is preferred.
Do you need characters? “Test”.toList // Makes a list of characters “Test”.toArray // Makes an array of characters Do you need bytes? “Test”.getBytes // Java provides this Do you need strings? “Test”.map(_.toString) // Vector of strings “Test”.sliding(1).toList // List of strings “Test”.sliding(1).toArray // Array of strings Do you need UTF-32 code points? Okay, that’s a …
No, the problem is that * is a reserved character in regexes, so you need to escape it. String [] separado = line.split(“\\*”); * means “zero or more of the previous expression” (see the Pattern Javadocs), and you weren’t giving it any previous expression, making your split expression illegal. This is why the error was …
