Thomas de Grivel d7719570 2023-11-22T16:41:15 fix compilation with clang

antirez 8087db33 2023-03-27T10:07:44 Multiline: just remember last num of rows, not max. For some reason, the old code was always cleaning the maximum number of rows used so far while editing in multi line mode. Actually we need to clean just the number of rows used by the last line. The old behavior created problems in multiplexing mode, where the line is refreshed at a different row, if the user used linenoiseHide() / show() in order to print something. With the new behavior, all looks fine, so far.

antirez a64257a8 2016-04-12T18:44:46 Hints: when only bold is set, use color 37 (white).

antirez 12a8680d 2016-04-12T17:59:33 Hints WIP
antirez d97e7665 2016-04-06T13:40:15 Copyright info updated.
antirez 94d9ddb2 2016-04-06T13:39:09 4096 bytes line limit removed when STDIN is not a tty.
antirez 80fd0569 2015-04-13T09:38:43 Version 1.0 Linenoise is used in multiple projects for enough time, let's tag this commit with a version number as requested into issue #88, so that we have an initial reference. Given the nature of the library, the version was also added in the linenoise C and header file as well so that it is easy to realize for people having a copy embedded somewhere if they are using the latest version.
antirez cf1bdf5f 2014-10-07T15:22:48 License file added. However the files linenose.c and linenose.h already had inline licenses.
antirez c1c5a026 2014-09-03T11:49:43 Move to end before return when in multi-line mode. This makes sure that if we are editing in multi-line mode a line that actually spawns across multiple lines, the next output performed by the application using linenoise will not overwrite the edited line.
antirez 01e723a0 2014-09-03T11:38:19 Replace ESC 999D with CR. OSX default Terminal app does not handle 999D well, the cursor will wrap back to the previous row in the last colum, instead of ignoring the sequence if the cursor is already at the left edge. In order to avoid reintroducing the nG sequence that is not compatible with base VT100 emulation and ANSI.SYS, we use CR that should be hopefully widely supported.
antirez c84d0a02 2014-09-03T10:11:31 Don't emit ESC [ n C with n=0. This fixes a bug introduced with ANSI.SYS compatibility. When we want to move at a specific column, we need to emit the sequence to move the cursor to the right (after we moved 999 positions to the left) only if we want to actually move right at least 1 position, since a count of zero will still move the cursor one position to the right.
antirez 471e7546 2014-09-03T09:51:29 Better specify the set of escapes used.
antirez 0a745fca 2014-09-03T09:30:32 Avoid CHA sequence for ANSI.SYS compatibility. Github user @welash proposed a change in issue #73 in order to improve the linenoise compatibility with older terminal emulators only able to deal with a subset of ANSI sequences, notably ANSI.SYS and VT100 terminals strictly able to handle the original set of VT100 escape sequences. In order to improve the compatibility, the CHA sequence was removed and translated to move 999 positions to the left, then move on the right for the desired number of positions. The CHA sequence was apparently added only with VT220, that's why it is not available everywhere. This commit features almost exactly the change proposed in issue #73 with a small fix for a bug in multi-line editing mode introduced by the patch.
antirez 828b9dac 2014-09-03T00:02:09 Remove trailing spaces from source code.
antirez c86280ed 2014-03-13T12:40:02 linenoiseHistoryAdd() reworked + duplicated lines prevented.
antirez 2a92a4d1 2014-03-13T12:27:53 Check read() return value in getCursorPosition().
antirez ca20f8c4 2014-03-13T12:25:14 Support for Home / End keys. Some terminal reports ESC [H and ESC [F, while some other reports ESC OH and ESC OF. We support both but there is at least another variant documented, hopefully no longer.
antirez 8447b2b0 2014-03-13T12:20:11 Fix right arrow handling. Bug introduced in recent refactoring.
antirez 9e1c2318 2014-03-13T12:04:36 If ioctl() fails get num of columns querying the terminal. This change makes linenoise both more robust if the ioctl() fails, and far more portable to non POSIX systems, since the ioclt() to query the terminal was probably one of the non trivial parts to replace. The code is inspired to Andreas Kupries commit 24186e99 on the win32 Linenoise port from Steve Bennett, but is a complete reimplementation.
antirez fb015dab 2014-03-13T11:08:37 linenoiseEdit() escapes processing refactor.
antirez 4115b616 2014-03-13T10:30:31 Compare human readable key codes with chars literals. Many sequences are actually human readable and fall into the printable ASCII subset, they are a lot more recognizable when written as chars compared to numbers. For example up arrow is sent back from the terimal as ESC [A, and so forth. This commit makes the code speak the same "language" that you find in any terminal escape sequences documentation.
antirez 3e521d47 2014-03-13T10:19:07 linenoisePrintKeyCodes(): show character if printable.
antirez f698ec47 2014-03-13T10:08:39 Rename Scan codes -> Key codes. What we print in debug mode using the option (now) called --keycodes are not the scan codes, but the key codes returned by the terminal (a more higher level representation of the keys pressed). This commit fixes the word used.
antirez cb0d0400 2014-03-12T23:49:54 Fix Del key processing + minor cleanup.
antirez bbcf9bf2 2014-03-12T23:38:40 Scan codes debugging functionality. ./linenoise_example --scancodes
antirez a05ab23d 2014-03-12T23:25:27 Use the two-reads fix for the additional escapes as well. See commit e153bd8 for more information. The gist is that slow terminals may return a short read of 1 byte.
antirez d5ec9cbb 2014-03-12T23:10:48 Arrow scancodes replaced with enums in linenoiseEdit().
Nick Gasson e153bd83 2014-01-06T11:04:02 Fix escape sequence processing when only one byte available The read call in the escape sequence processing does not handle the case where only the first byte is available. This can happen for example on a slow serial terminal. Comment by @antirez: I reworked the code for brevity, for historical reasons here is the proposed patch. I believe my fix should be functionally equivalent. Original fix: case 27: /* escape sequence */ /* Read the next two bytes representing the escape sequence. */ - if (read(fd,seq,2) == -1) break; + { + ssize_t b = read(fd, seq, 2); + + if (b < 0) break; + + if (b == 1) { + b = read(fd,&seq[1], 1); + if (b != 1) { + break; + } + } + } See PR #47.

antirez cbf172f7 2014-03-12T13:10:44 Handle malloc error in linenoiseAddCompletion(). We just don't add the entry on out of memory to avoid to break the API with previous versions of Linenoise.
antirez aed9d1af 2014-03-12T13:04:22 Refresh line with single write to avoid flickering. Escape sequences and actual content to write to the terminal is now accumulated into an heap allocated buffer that is flushed with a single write at the end. This avoids a flickering effect making linenoise more professional looking ;-)
