2019-05-25Fix error handling in if-shell.nicm
2019-05-23Replace the split parser code (cfg.c and cmd-string.c) with a singlenicm
parser using yacc(1). This is a major change but is clearer and simpler and allows some edge cases to be made more consistent, as well as tidying up how aliases are handled. It will also allow some further improvements later. Entirely the same parser is now used for parsing the configuration file and for string commands. This means that constructs previously only available in .tmux.conf, such as %if, can now be used in string commands (for example, those given to if-shell - not commands invoked from the shell, they are still parsed by the shell itself). The only syntax change I am aware of is that #{} outside quotes or a comment is now considered a format and not a comment, so #{ is now a syntax error (notably, if it is at the start of a line). This also adds two new sections to the man page documenting the syntax and outlining how parsing and command execution works. Thanks to everyone who sent me test configs (they still all parse without errors - but this doesn't mean they still work as intended!). Thanks to Avi Halachmi for testing and man page improvements, also to jmc@ for reviewing the man page changes.
2018-08-27Memory leaks, from Gang Fan in GitHub issue 1453.nicm
2018-08-23Move job struct into job.c.nicm
2018-05-24Make server_client_get_cwd used (almost) everywhere we need to work outnicm
the cwd, and do not fall back to "." as it is pretty useless. GitHub issue 1331.
2018-03-08Add a missing client-detached hook when the server shuts down, and donicm
not exit until jobs started from run-shell/if-shell have finished (add a job flags member and a flag to indicate other jobs). GitHub issue 1245.
2017-04-25if-shell doesn't need to queue its error message into a callback, and innicm
fact it can't do so because the item it was working with will have been freed. Reported by Daniel Hahler.
2017-04-22Get rid of the extra layer of flags and cmd_prepare() and just store thenicm
CMD_FIND_* flags in the cmd_entry and call it for the command. Commands with special requirements call it themselves and update the target for hooks to use.
2017-04-22Fix if-shell without a client (so in the config file). Reported by Theonicm
Buehler.
2017-04-21Store state shared between multiple commands in the queue in a sharednicm
structure.
2017-04-20If a #() command doesn't exit, use its most recent line of output (itnicm
must be a full line). Don't let it redraw the status line more than once a second. Requested by someone about 10 years ago...
2017-03-08Add a helper function for the most common format_create/defaults/expandnicm
pattern.
2017-02-03Add a window or pane id "tag" to each format tree and use it to separatenicm
jobs, this means that if the same job is used for different windows or panes (for example in pane-border-format), it will be run separately for each pane.
2017-01-15It is silly for cmd_list_parse to return an integer error when it couldnicm
just return NULL.
2016-10-16Mass rename struct cmd_q to struct cmdq_item and related.nicm
2016-10-16Rewrite command queue handling. Each client still has a command queue,nicm
but there is also now a global command queue. Instead of command queues being dispatched on demand from wherever the command happens to be added, they are now all dispatched from the top level server loop. Command queues may now also include callbacks as well as commands, and items may be inserted after the current command as well as at the end. This all makes command queues significantly more predictable and easier to use, and avoids the complex multiple nested command queues used by source-file, if-shell and friends. A mass rename of struct cmdq to a better name (cmdq_item probably) is coming.
2016-10-13Trying to do hooks generically is way too complicated and unreliable andnicm
confusing, particularly trying to automatically figure out what target hooks should be using. So simplify it: - drop before hooks entirely, they don't seem to be very useful; - commands with special requirements now fire their own after hook (for example, if they change session or window, or if they have -t and -s and need to choose which one the hook uses as current target); - commands with no special requirements can have the CMD_AFTERHOOK flag added and they will use the -t state. At the moment new-session, new-window, split-window fire their own hook, and display-message uses the flag. The remaining commands still need to be looked at.
2016-10-10Add static in cmd-* and fix a few other nits.nicm
2016-10-09Pass file/line to new command for if-shell so that errors appearnicm
sensibly.
2016-04-29Expand client formats (like run-shell), from Stephen M Coakley.nicm
2016-04-29Final parts of command hooks, add before- and after- hooks to each command.nicm
2016-03-01Remove some more unused variables, and use RB_FOREACH_SAFE innicm
key_bindings_unref_table.
2015-12-14Instead of combined flags for -c, -s, -t, split into different setsnicm
using an enum and simplify the parsing code.
2015-12-13Use member names in cmd_entry definitions so I stop getting confusednicm
about the order.
2015-12-13Instead of every command resolving the target (-t or -s) itself, preparenicm
the state (client, session, winlink, pane) for it it before entering the command. Each command provides some flags that tell the prepare step what it is expecting. This is a requirement for having hooks on commands (for example, if you hook "select-window -t1:2", the hook command should to operate on window 1:2 not whatever it thinks is the current window), and should allow some other target improvements. The old cmd_find_* functions remain for the moment but that layer will be dropped later. Joint work with Thomas Adam.
2015-12-11Add cmdq as an argument to format_create and add a format for thenicm
command name (will also be used for more later).
2015-12-08Remove format_create_flags and just pass flags to format_create.nicm
2015-11-20Memory leaks and an uninitialized part of utf8_data, from Patrick Palka.nicm
2015-10-31Because pledge(2) does not allow us to pass directory file descriptorsnicm
around, we can't use file descriptors for the working directory because we will be unable to pass it to a privileged process to tell it where to read or write files or spawn children. So move tmux back to using strings for the current working directory. We try to check it exists with access() when it is set but ultimately fall back to ~ if it fails at time of use (or / if that fails too).
2015-09-16Rename cmd_q dead flag to a general flags bitmask (will be more flags later).nicm
2015-04-24Set working directory for run-shell and if-shell.nicm
2015-04-21The free callback could end up being fired before the done callbacknicm
(happens on Cygwin), so use a reference count instead of a single flag. SF bug 188 reported by "iceboy".
2015-04-21Pass mouse events through to commands for if-shell.nicm
2015-04-19Rewrite of tmux mouse support which was a mess. Instead of havingnicm
options for "mouse-this" and "mouse-that", mouse events may be bound as keys and there is one option "mouse" that turns on mouse support entirely (set -g mouse on). See the new MOUSE SUPPORT section of the man page for description of the key names and new flags (-t= to specify the pane or window under mouse as a target, and send-keys -M to pass through a mouse event). The default builtin bindings for the mouse are: bind -n MouseDown1Pane select-pane -t=; send-keys -M bind -n MouseDown1Status select-window -t= bind -n MouseDrag1Pane copy-mode -M bind -n MouseDrag1Border resize-pane -M To get the effect of turning mode-mouse off, do: unbind -n MouseDrag1Pane unbind -temacs-copy MouseDrag1Pane The old mouse options are now gone, set-option -q may be used to suppress warnings if mixing configuration files.
2015-02-05Wrap all the individual format_* calls in a single format_defaultsnicm
functions.
2014-12-02Add -F to if-shell to allow it to be used to check for format or optionnicm
values rather than executing a command.
2014-10-20Instead of setting up the default keys by building the key structnicm
directly with a helper function in the cmd_entry, include a table of bind-key commands and pass them through the command parser and a temporary cmd_q. As well as being smaller, this will allow default bindings to be command sequences which will probably be needed soon.
2013-10-10Make cmdq->client_exit a tristate (-1 means "not set") so that ifnicm
explicitly set it can be copied from child to parent cmdq by if-shell and source-file. This fixes using attach or new. From Chris Johnsen.
2013-03-25Try to establish client for run-shell and if-shell if no -t.Nicholas Marriott
2013-03-25Extend jobs to support writing and use that for copy-pipe instead ofNicholas Marriott
popen, from Chris Johnsen.
2013-03-24Add a command queue to standardize and simplify commands that call otherNicholas Marriott
commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.
2013-03-24Expand format variables in the run-shell and if-shell shell commands,Nicholas Marriott
from Thiago Padilha.
2013-03-22Add functions to allocate and free command contexts rather than doing itNicholas Marriott
all on the stack.
2012-08-11Remove dead code, from Sean Estabrooks.Nicholas Marriott
2012-07-11Make command exec functions return an enum rather than -1/0/1 values andNicholas Marriott
add a new value to mean "leave client running but don't attach" to fix problems with using some commands in a command sequence. Most of the work by Thomas Adam, problem reported by "jspenguin" on SF bug 3535531.
2012-07-10xfree is not particularly helpful, remove it. From Thomas Adam.Nicholas Marriott
2011-10-27Didn't really think the else behaviour through - requiring argv toNicholas Marriott
contain "else" is silly so just omit that, also some manpage tweaks. From Tiago Cunha.
2011-10-18Add an else clause for if-shell, from "arno-" on SourceForge.Nicholas Marriott
2011-05-25Nuke a redundant if statement, from Tiago Cunha.Nicholas Marriott
2011-01-26Simplify the way jobs work and drop the persist type, so all jobs areNicholas Marriott
fire-and-forget. Status jobs now managed with two trees of output (new and old), rather than storing the output in the jobs themselves. When the status line is processed any jobs which don't appear in the new tree are started and the output from the old tree displayed. When a job finishes it updates the new tree with its output and that is used for any subsequent redraws. When the status interval expires, the new tree is moved to the old so that all jobs are run again. This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands of identical persistent jobs and high memory use (this can still be achieved by adding "sleep 30" but that is much less likely to happen by accident).
