=== tio v1.38 === Changes since tio v1.37: * Redirect error messages to stderr * Improve help and man page * Mention config file in --help * Fix running without config file * Fix config file error messages * Redirect error messages to stderr * Add repology packaging status * Fix parsing of default settings Default configuration file settings were not parsed in case a section was matched. Now we make sure that the default (unnamed) settings are always parsed. * Append to existing log file (no truncation) * Add socket info to show configuration * Print socket info at startup * Fix socket option parsing Peter Collingbourne: * Match user input against config section names if pattern matching was unsuccessful. This allows for better config file ergonomics if the user has a diverse set of serial devices as the name does not need to be specified in the config file twice. * Add support for external control via a Unix domain socket. This feature allows an external program to inject output into and listen to input from a serial port via a Unix domain socket (path specified via the -S/--socket command line flag, or the socket config file option) while tio is running. This is useful for ad-hoc scripting of serial port interactions while still permitting manual control. Since many serial devices (at least on Linux) get confused when opened by multiple processes, and most commands do not know how to correctly open a serial device, this allows a more convenient usage model than directly writing to the device node from an external program. Any input from clients connected to the socket is sent on the serial port as if entered at the terminal where tio is running (except that ctrl-t sequences are not recognized), and any input from the serial port is multiplexed to the terminal and all connected clients. Sockets remain open while the serial port is disconnected, and writes will block. Example usage 1 (issue a command): echo command | nc -UN /path/to/socket > /dev/null Example usage 2 (use the expect command to script an interaction): #!/usr/bin/expect -f set timeout -1 log_user 0 spawn nc -UN /path/to/socket set uart $spawn_id send -i $uart "command1\n" expect -i $uart "prompt> " send -i $uart "command2\n" expect -i $uart "prompt> " lexaone: * fix for using option 'log' without 'log-filename' in config file Changes since tio v1.36: * Make libinih a fallback dependency This means that in case meson does not find libinih it will automatically clone libinih and include it in the build. The libinih library is reconfigured to be statically built so that no shared object will be installed. Sylvain LAFRASSE: * Fix timestamp parsing in INI conf * Factorize timestamp parsing to be coherent with command line format in configuration file. Changes since tio v1.35: * Add support for defaults in config file If no section name is specified the configuration will be considered the default one. This allows to set e.g. a default color code for sections which do not configure a color code. * Handle SIGHUP Handle SIGHUP so that the registered exit handlers are called to restore the terminal back to its orignal state. * Add color configuration support * Bypass unused result warnings * Force dependency on libinih Configuration file support is considered a mandatory feature. * Update headers * Update AUTHORS * Update man page * Move string_to_long() to misc.c * Update CircleCI config * Update tio gif * Update README * Update LICENSE date * Remove redundant COPYING file Liam Beguin: * Document configuration file options * Add support for a configuration file * misc: add _unused macro Some parameters are expected to be unused. Add a basic macro to mute these compiler warnings. * options: expose string_to_long() Expose string_to_long() so that other source files can use it. Changes since tio v1.34: * Add support for automatically generated log filename Automatically generate log filename if none is provided. The auto generated file name is on the form: "tio_DEVICE_YYYY-MM-DDTHH:MM:SS.log" * Add support for configurable timestamp format Also changes default timestamp format from ISO8601 to classic 24-hour format as this is assumed to be the format that most users would prefer. And reintroduces strict but optional ISO8601 format. This feature allows to easily add more timestamp formats in the future. * Reintroduce asm-generic/ioctls.h It is needed for ppc builds. * Add macro hack to workaround older buggy glibc Robey Pointer: * Add support for high bps on OS X Changes since tio v1.33: * Fix setspeed2 compilation * Only apply color formatting when using color option To help the color blind who may use custom terminal foreground / background colors. * Update README * Add '-c, --color' option Allow user to select which ANSI color code to use to colorize the tio text. To successfully set the color the color code must be in the range 0..255. If color code is negative tio will print all available ANSI colors. The default color is changed to bold white to make tio defaults usable for most users, including color blind users. * Fix setspeed2 check * Fix meson header check string * Reintroduce long timestamp format But make the timestamp format RFC3339 compliant instead. The RFC states: NOTE: ISO 8601 defines date and time separated by "T". Applications using this syntax may choose, for the sake of readability, to specify a full-date and full-time separated by (say) a space character. This way we keep the information specified by ISO 8601 but make it more human readable which is better for the console output. * Update version year Sylvain LAFRASSE: * Fix TTY device listing on Darwin. (#136) * Fix TCGETS2 search on Darwin. Changes since tio v1.32: * Show auto connect status in show configuration * Use '#pragma once' in all headers * Improve printed output Get rid of inconsistencies in the printed output (error printing, colors, etc.). Prepare for user configurable color. * Rename option -i to -L * Shorten timestamp * Shorten timestamp description We do not need the date part of the timestamp. It simply takes up too much precious line space. In case of logging to file, one can easily conclude the date from the file date information. * Replace Travis with circleCI * Replace autotools with meson To introduce much simpler build configuration which is also easier to maintain. * Add list serial devices feature For convenience, add a --list-devices option which lists the available serial devices. * Cleanup: Use dot notation for default options struct * Update AUTHORS * Add command to show version The key sequence ctrl-t v will now show the version of tio. * Align format of timestamps * Add Sylvain as official co-maintainer Sylvain LAFRASSE: * Add '-t' option description for time stamping. * Add description for time stamping. * Resolved tio/tio#84: Added timestamps in log file if enabled. attila-v: * Refine timestamps with milliseconds and ISO-8601 format (#129). * Show milliseconds too in the timestamp (#114) and log file (#124) * Change timestamp format to ISO-8601. Yin Fengwei: * Output newline on stdout with hex print mode This is to fix the issue #104. The timestamp will always be printed at the beginning of line: [10:25:56] Switched to hexadecimal mode 0d 0a 0d [10:25:57] 41 43 52 4e 3a 5c 3e 0d 0a 0d [10:25:58] 41 is changed to: [12:34:56] 45 72 72 6f 72 3a 20 49 6e 76 61 6c 69 64 20 [12:34:56] 41 43 52 4e 3a 5c 3e [12:34:56] 41 43 52 4e 3a 5c 3e [12:34:57] 41 43 52 4e 3a 5c 3e 6c 73 Jakob Haufe: * Make comparison POSIX compliant String comparison with == is not POSIX compliant and can fail with e.g. dash. Henrik Brix Andersen: * Add bash completion of tty devices. * Add -t/--timestamp to bash completion script. Henner Zeller: * Local echo: show character by character even if stdout buffered. Björn Stenberg: * Show error when failing to open a tty Alban Bedel: * Fix out of tree builds Out of tree builds are currently broken because $(top_srcdir)src/include is not in the search path. In tree builds are working because autconf add $(top_builddir)/src/include to the search path for the generated config.h. As $(top_builddir) and $(top_srcdir) are identical during in tree builds the search path still end up beeing somehow correct. To fix this add -I$(srcdir)/include to the CPPFLAGS in Makefile.am. Fabrice Fontaine: * src/setspeed2.c: fix redefinition of termio Include ioctls.h and termbits.h from asm-generic instead of asm to avoid build failures. Erik Moqvist * Exit if output speed cannot be set. Lars Kellogg-Stedman: * fflush() after putchar() for print_hex and print_normal In order for local echo to work properly, we have to either call fflush(stdout) after every character or just disable line buffering. This change calls fflush() after putchar(). * Disable line buffering in stdout In order for local echo to work properly, we have to either call fflush(stdout) after every character or just disable line buffering. This change uses setbuf(stdout, NULL) to do the latter. George Stark: * dont show line state if ioctl failed * add serial lines manual control arichi: * Flush every local echo char Flush stdout at every char in case it happens to be buffered. Mariusz Midor: * Newline: handle booth NL and CR Flag ONLCRNL expects code \n after press Enter, but on some systems \r is send instead. Changes since tio v1.31: * Update AUTHORS * Minor code style cleanups * Cleanup print macros * Flush output Make sure output is transmitted immediately by flushing the output. Robey Pointer: * add optional timestamps with "-t" or "C-t T", toggle a timestamp prefix to each line. Jakub Wilk: * Fix typos Sylvain Lafrasse: * Added macOS compatibility * Made O_NONBLOCK flag to open() call specific to macOS only. * Added macOS-related details. * Added O_NONBLOCK flag to open() call for macOS (10.13.6) compatibility. Changes since tio v1.30: * Update date * Update AUTHORS Henner Zeller: * Clarify the input/output variable names (No-op change) * Organize options the same sequence they are mentioned in cmdline help. * Update README. * Map CR->NL locally on output instead of using tio.c_oflag |= OCRNL. This mostly is intended to have local echo output exactly what is sent to the remote endpoint. A nice side-effect is, that it also fixes tty-implementations, that can't deal with the OCRNL flag on tio.c_oflag. * Provide local-echo option. Can be switched on with -e on the command line. Can be toggled with Ctrl t e while program is running. * Write to logfile as soon as we have the data, don't buffer. Logfiles are important to see what happened, in particular if something unexpected happened; so we want to make sure that the logfile is flushed to disk. Before this change, the logfile was typically written at the end in a large chunk as the default (large) buffering applied. Now, characters are written out ASAP, so it is possible to get a live-view with a tail -f Changes since tio v1.29: * Update README * Update man page and bash completion * Update AUTHORS qianfan Zhao: * ONLCRNL: change the method to map NL to CR-NL Changes since tio v1.28: * Add mapping flags INLCRNL and ODELBS The following new mapping flags are added: INLCRNL: Map NL to CR-NL on input. ODELBS: Map DEL to BS on output. Flags requested and tested by Jan Ciger (janoc). Changes since tio v1.27: * Update README * Update AUTHORS * Add snap status to README.md * Add README.md to prettify GitHub page * Add missing header Petr Vaněk: * Add missing header file under musl-libc Musl's inclusion tree slightly differs from glibc, therefore TCGETS2 is not reachable through sys/ioctl.h, so asm/ioctls.h needs to be included too. Jakub Wilk: * Fix grammar and typos Changes since tio v1.26: * Update man page * Add support for setting non-standard baudrates Support for non-standard baudrate settings will be automatically enabled if the termios2 interface is detected available. However, to play it safe, the old and widely supported termios interface will still be used when setting standard baudrates. * Cleanup * Update AUTHORS Changes since tio v1.25: * Reconfigure stdin Make stdin behave more raw'ish. In particular, don't translate CR -> NL on input. * Add special character map feature Add a --map option which allows mapping special characters, in particular CR and NL characters which are used in various combinations on various platforms. * Cleanup * Update AUTHORS * Update README * Mention website * Update man page Changes since tio v1.24: * Fix error applying new stdout settings On Fedora 26 tio will quit with the following error message: "Error: Could not apply new stdout settings (Invalid argument)" In case of Fedora, it turns out that the new stdout settings used are a bit too aggressive because an empty termios structure is used. To remedy this we reuse the existing stdout settings and only reconfigure the specific options we need to make a "raw" stdout configuration. * Remove unused pkgconfig in configure * Code cleanup Remove unused variable. Changes since tio v1.23: * Optimize clear screen command Replaced system call with inline ANSI/VT100 clear screen code sequence * Fix bash completion installation Fixed the configure script to avoid that the bash completion script gets installed outside of the prefix location. The default install location is now $prefix/share/bash-completion/completions. Use the configure option '--with-bash-completion-dir=PATH' if you need to install the bash completion script elsewhere. Jakub Wilk: * Add missing commas in conditional sentences Changes since tio v1.22: * Update copyright headers Jakub Wilk: * Fix typos Changes since tio v1.21: * Update man page date * Update copyright year * Code cleanup * Update README and man page Changes since tio v1.20: * Add support for hexadecimal mode A new key command 'ctrl-t h' is introduced which toggles between hexadecimal mode and normal mode. When in hexadecimal mode data received will be printed in hexadecimal. * Do not distribute src/bash_completion/tio Since the bash completion tio script is now autogenerated from tio.in it should not be distributed in the tarball. * Add missing forward flag * Update AUTHORS file Adam Borowski: * 'ctrl-t b' to send serial break. Jakub Wilk: * Removed git commit references from ChangeLog ChangeLog is primary useful for users who don't have the git repository at hand. Replace git commit references with version numbers; or if the change only cleans up another change with no release in between, remove the changelog item completely. Changes since tio v1.19: * Added more error handling of terminal calls Also removed duplicate terminal flushing calls. * Revert "Added support for non-standard baud rates" This reverts a change made in v1.18. Reverting because supporting non-standard or arbitrary baud rates is troublesome because the c library provides no means of doing so and even if bare metal linux kernel interface is used it will not work on all Linux kernels version. Changes since tio v1.18: * Rearranged key commands Rearranged the key commands: ctrl-t c (clear screen) is now ctrl-t l which is similar to the well known shell ctrl-l ctrl-t i (show settings information) is now ctrl-t c (show configuration) Updated man page accordingly. * Added "ctrl-t c" key command to clear screen Changes since tio v1.17: * Updated man page * Added support for non-standard baud rates Only enabled when possible, that is, when the BOTHER definition is available. It is untested but it should work as described here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=683826 Some Cypress USB<->serial devices supposedly supports arbitrary speeds. * Generate baudrate switch cases based on detection Support a single source of baud rate configuration as discussed in https://github.com/tio/tio/issues/45 . To do so, autogeneration of the switch cases which do the baud rate option value check and configuration/conversion in tty_configure() is introduced via a single macro. Just to be safe, this change also enables configure detection of all baud rates, including the ones previously assumed supported by most/all systems (POSIX). * Minor cleanup * Exit when not a tty device in autoconnect mode Jakub Wilk: * Added non-standard baud rates that are defined on FreeBSD * Capitalized "GitHub" in README Changes since tio v1.16: * Compacted tty_configure() a bit * Fixed automatic baud rate enablement * Minor cleanups * Added autodetection of available baud rates Various platforms support different baud rates. To avoid adding platform specific handling generic baud rate detection tests are introduced in the configure script. Successfully detected baud rates are automatically enabled. This applies to both the C code and the bash completion script. Note: Baud rates below 57600 are defined by POSIX-1 and supported by most platforms so only baud rate 57600 and above are tested. * Updated bash-completion * Fixed printf() format type * Added Travis build configuration Jakub Wilk: * Generated bash completion at configure time * Reduce code duplication in baud rate detection * Add support for baud rates 200 and 1800 * Fixed baudrate type Changes since tio v1.15: * Updated man page * Updated README * Removed obsolete packaging files * Removed use of deprecated bzero() Changes since tio v1.14: * Removed + to remove potential confusion * Added input digit checks * Fixed license string * Introduced tty_configure() Moved tty configuration actions to tty_configure() in tty.c. This way options.c is strictly about parsing options nothing else. * Function names cleanup * Updated AUTHORS file Added Nick who created the new tio package for Arch Linux. * Fixed tx/rx counters type Jakob Haufe: * Include config.h before standard headers Large file support was meant to be enabled in v1.11. This change enables it for real. Changes since tio v1.13: * Fixed tio_printf macro * Fixed launch hints Fixed launch hints not being printed in no autoconnect mode. * Added 'ctrl-t ?' to list available commands * Fixed log mechanism To avoid echoing only log what is received from tty device. * Improved tio output Added titles and indentation to commands output for clearer separation when firing commands repeatedly. Also added print of tio version and quit command hint at launch. * Cleaned up tio print mechanism Jakub Wilk: * Fixed grammar "allow" is a transitive verb, which requires an object, so "allow to " is ungrammatical. * Fixed typo Changes since tio v1.12: * Fixed some error prints * Fixed error printing for no autoconnect mode Always print errors but only print silent errors when in no autoconnect mode. * Added key command for showing session settings A new key command "ctrl-t i" is added to allow the user to display the various session settings information (baudrate, databits, log file, etc.). This is useful in case you have a running session but have forgotten what the settings are. Changes since tio v1.11: * Consolidated command key handling * Moved delay mechanism into separate function * Retired obsolete usleep() Replaced with nanosleep() * Added simple tx/rx statistics command (ctrl-t s) To display the total number of bytes transmitted/received simply perform the 'ctrl-t s' command sequence. This feature can be useful when eg. trying to detect non-printable characters. * Further simplification of key handling Changed so that the "ctrl-t ctrl-t" sequence is now simply "ctrl-t t" to send the ctrl-t key code. This is inspired by screen which does similar to send its command key code (ctrl-a a). This change also eases adding new key commands if needed. Updated man page accordingly. * Cleaned up and simplified key handling Jakub Wilk: * Insert output delay only if something was output Changes since tio v1.10: * Enabled large file support (LFS) Added autotools AC_SYS_LARGEFILE to support 64 bit file size handling. * Updated tio title Changes since tio v1.9: * Introduced lock on device file Tio will now test for and obtain an advisory lock on the tty device file to prevent starting multiple sessions on the same tty device. * Updated AUTHORS Jakub Wilk: * Treat EOF on stdin as error Changes since tio v1.8: * Cleanup of error handling Introduced consistent way of handling errors and printing error messages. Also upgraded some warnings to errors. * Updated localtime() error message * Cleanup Jakub Wilk: * Fix error handling for select() Previously the error handling code for select() was unreachable. * Removed unneeded quotes from AM_CFLAGS * Expanded tabs * Fixed setting "tainted" Set "tainted" if and only if any character was read from the device. Ctrl-t is no longer sent to the device on exit, so the trick to avoid its echo is not necessary. Characters read from stdin don't directly affect output, so they shouldn't enable "tainted". * Used \r in color_printf() \033[300D is an unusual way to move the cursor back to column 1. Use straightforward \r instead. * Added missing \r\n to warning messages \n alone is not enough, because the terminal is in raw mode. Changes since tio v1.7: * Fixed enablement of compiler warnings * Fixed log_open() prototype * Fixed index error wrt ctrl-t detection * Fixed handling of ctrl-t Before, when exercising the quit key sequence (ctrl-t + q) the ctrl-t code (0x14) would be sent. This is now fixed so that it is not sent. However, in case it is needed to send ctrl-t to the device it is possible by simply repeating the ctrl-t. Meaning, ctrl-t + ctrl-t = ctrl-t sent to device. * Improved error handling Fixes a memory leak and avoids aggressive busy looping when problems accessing tty device. * Removed redundant log_close() call * Enabled compiler warnings Jakub Wilk: * Stopped copying arguments to fixed-size buffers Don't needlessly copy command-line arguments into fixed-size buffers. Previously the program crashed if an overlong pathname was provided on the command line. Also, some systems (such as GNU Hurd) don't define MAXPATHLEN at all. * Added const to log_open() prototype * Completed the ^g to ^t transition In v1.7 the escape key was changed from ^g to ^t, but some code and comments still referred to the old key. * Used HTTPS for tio.github.io * Man page beautification * Bumped date in man page * Improve man page formatting Use regular font for metacharacters such as "[]", "," or "|"; use italic font for metavariables. * Fixed hyphen vs minus vs em-dash confusion in man page - prints as hyphen; \- prints as minus sign; \em prints as em-dash. Changes since tio v1.6: * Changed escape key from ^g to ^t After renaming to "tio" it makes sense to change the escape key accordingly. Hence, the new escape key is ^t. Meaning, in session, its now ctrl-t + q to quit. Jakub Wilk: * Fixed silly "tio or tio" in man page * Fixed typo
