This is the version of CCAN which CLN was using at the time these were taken. Unfortunately lots of whitespace has been changed, but AFAICT no source changes. Here's the command I ran (with ../ccan checked out to 1ae4c432): ``` make update-ccan CCAN_NEW="alignof array_size build_assert check_type container_of cppmagic likely list mem short_types str structeq take tal tal/str typesafe_cb utf8 endian crypto/sha256" ``` Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: William Casarin <jb55@jb55.com>

/**

|
* tal/str - string helper routines which use tal
|
|
*
|
|
* This is a grab bag of functions for string operations, designed to enhance
|
|
* the standard string.h; these are separated from the non-tal-needing
|
|
* string utilities in "str.h". Each string created by this library
|
|
* will have tal_count() equal to strlen() + 1 (assuming you didn't create
|
|
* a string containing a NUL, such as using tal_fmt("%c", 0)).
|
|
*
|
|
* Example:
|
|
* #include <ccan/tal/str/str.h>
|
|
* #include <ccan/tal/grab_file/grab_file.h>
|
|
* #include <err.h>
|
|
*
|
|
* // Dumb demo program to double-linespace a file.
|
|
* int main(int argc, char *argv[])
|
|
* {
|
|
* char *textfile;
|
|
* char **lines;
|
|
*
|
|
* if (argc > 2)
|
|
* errx(1, "Takes 0 or 1 arguments");
|
|
* // Grab lines in file.
|
|
* textfile = grab_file(NULL, argv[1]);
|
|
* if (!textfile)
|
|
* err(1, "Failed reading %s", argv[1]);
|
|
* lines = tal_strsplit(textfile, textfile, "\n", STR_EMPTY_OK);
|
|
*
|
|
* // Join them back together with two linefeeds.
|
|
* printf("%s", tal_strjoin(textfile, lines, "\n\n", STR_TRAIL));
|
|
*
|
|
* // Free everything, just because we can.
|
|
* tal_free(textfile);
|
|
* return 0;
|
|
* }
