│ │
│ Bestline ── Library for interactive pseudoteletypewriter command │
│ sessions using ANSI Standard X3.64 control sequences │
│ │
│ OVERVIEW │
│ │
│ Bestline is a fork of linenoise (a popular readline alternative) │
│ that fixes its bugs and adds the missing features while reducing │
│ binary footprint (surprisingly) by removing bloated dependencies │
│ which means you can finally have a permissively-licensed command │
│ prompt w/ a 30kb footprint that's nearly as good as gnu readline │
│ │
│ EXAMPLE │
│ │
│ main() { │
│ char *line; │
│ while ((line = bestlineWithHistory("IN> ", "foo"))) { │
│ fputs("OUT> ", stdout); │
│ fputs(line, stdout); │
│ fputs("\n", stdout); │
│ free(line); │
│ } │
│ } │
│ │
│ CHANGES │
│ │
│ - Remove bell │
│ - Add kill ring │
│ - Fix flickering │
│ - Add UTF-8 editing │
│ - Add CTRL-R search │
│ - Support unlimited lines │
│ - Add parentheses awareness │
│ - React to terminal resizing │
│ - Don't generate .data section │
│ - Support terminal flow control │
│ - Make history loading 10x faster │
│ - Make multiline mode the only mode │
│ - Accommodate O_NONBLOCK file descriptors │
│ - Restore raw mode on process foregrounding │
│ - Make source code compatible with C++ compilers │
│ - Fix corruption issues by using generalized parsing │
│ - Implement nearly all GNU readline editing shortcuts │
│ - Remove heavyweight dependencies like printf/sprintf │
│ - Remove ISIG→^C→EAGAIN hack and use ephemeral handlers │
│ - Support running on Windows in MinTTY or CMD.EXE on Win10+ │
│ - Support diacratics, русский, Ελληνικά, 漢字, 仮名, 한글 │
