From 0517eb7d604da454213e42d55f477401dc7f7ebf Mon Sep 17 00:00:00 2001 From: Rob Landley Date: Sat, 13 Dec 2014 11:58:08 -0600 Subject: Add base64. The tizen guys wanted this. Yeah, I know there's base64 code in uuencode/uudecode, but that this has -i, input lines aren't of fixed length, encode/decode are in same file, there's no prefix/suffix code, it always writes to stdout... Eliminating the code duplication wouldn't be worth the if/else I'd have to add, so I just did a new one. Factored out the base64 table init into lib.c though: that was worth sharing. --- lib/lib.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'lib') diff --git a/lib/lib.c b/lib/lib.c index 33be44b6..490235f4 100644 --- a/lib/lib.c +++ b/lib/lib.c @@ -571,6 +571,21 @@ void crc_init(unsigned int *crc_table, int little_endian) } } +// Init base64 table + +void base64_init(char *p) +{ + int i; + + for (i = 'A'; i != ':'; i++) { + if (i == 'Z'+1) i = 'a'; + if (i == 'z'+1) i = '0'; + *(p++) = i; + } + *(p++) = '+'; + *(p++) = '/'; +} + // Quick and dirty query size of terminal, doesn't do ANSI probe fallback. // set x=80 y=25 before calling to provide defaults.
