My assumption has always been that the programming term originated from the following definition of the word “string” (from Merriam-Webster): (1): a series of things arranged in or as if in a line <a string of cars> <a string of names> (2): a sequence of like items (as bits, characters, or words) Since a string … Read more
Another way: x=$’Some\nstring’ readarray -t y <<<“$x” Or, if you don’t have bash 4, the bash 3.2 equivalent: IFS=$’\n’ read -rd ” -a y <<<“$x” You can also do it the way you were initially trying to use: y=(${x//$’\n’/ }) This, however, will not function correctly if your string already contains spaces, such as ‘line … Read more
Yes, indexing into a string is not available in Rust. The reason for this is that Rust strings are encoded in UTF-8 internally, so the concept of indexing itself would be ambiguous, and people would misuse it: byte indexing is fast, but almost always incorrect (when your text contains non-ASCII symbols, byte indexing may leave … Read more
If it’s for a (few) specific extension(s), you can add your own require.extensions handler: var fs = require(‘fs’); require.extensions[‘.txt’] = function (module, filename) { module.exports = fs.readFileSync(filename, ‘utf8’); }; var words = require(“./words.txt”); console.log(typeof words); // string Otherwise, you can mix fs.readFile with require.resolve: var fs = require(‘fs’); function readModuleFile(path, callback) { try { var … Read more
You can try RuneCountInString from the utf8 package. returns the number of runes in p that, as illustrated in this script: the length of “World” might be 6 (when written in Chinese: “世界”), but the rune count of “世界” is 2: package main import “fmt” import “unicode/utf8” func main() { fmt.Println(“Hello, 世界”, len(“世界”), utf8.RuneCountInString(“世界”)) } … Read more
You can parse a string into an integer with int.parse(). For example: var myInt = int.parse(‘12345’); assert(myInt is int); print(myInt); // 12345 Note that int.parse() accepts 0x prefixed strings. Otherwise the input is treated as base-10. You can parse a string into a double with double.parse(). For example: var myDouble = double.parse(‘123.45’); assert(myDouble is double); … Read more
Swift 4 includes support for multi-line string literals. In addition to newlines they can also contain unescaped quotes. var text = “”” This is some text over multiple lines “”” Older versions of Swift don’t allow you to have a single literal over multiple lines but you can add literals together over multiple lines: var … Read more
grep -nr ‘yourString*’ . The dot at the end searches the current directory. Meaning for each parameter: -n Show relative line number in the file ‘yourString*’ String for search, followed by a wildcard character -r Recursively search subdirectories listed . Directory for search (current directory) grep -nr ‘MobileAppSer*’ . (Would find MobileAppServlet.java or MobileAppServlet.class or … Read more
The Like operator is already available in VBA: If “I am studying at University of Texas at Arlington” Like “*Univ*of*Texas*” Then MsgBox “Yes, it is!” End If
The first version doesn’t work as there is only one loop variable v, which has the same address in each iteration. The loop variable is assigned in each iteration, which changes its value but not its address, and you append this same address in each iteration. A possible solution is what you proposed: to append … Read more
