Author: Akib Azmain Turja <[email protected]>
Commit: Akib Azmain Turja <[email protected]>
Use terminal parameters to set callback functions
Also make sure the terminal passed as arguments to API
functions is live.
* eat.el (eat--t-term): Update default value of slot 'params'.
* eat.el (eat-term-p, eat-term-live-p): New function.
* eat.el (eat--t-ensure-live-term): New macro.
* eat.el (eat--t-with-env, eat-term-parameter, eat-term-size)
(eat-term-set-parameter, eat-term-cursor-type, eat-term-end)
(eat-term-beginning, eat-term-display-cursor, eat-term-title)
(eat-term-in-alternative-display-p, eat-term-input-event)
(eat-term-send-string, eat-term-send-string-as-yank): Ensure
the terminal passed as argument is live.
* eat.el (eat-term-delete): Ensure the terminal passed as
argument is live. Mark terminal as deleted.
* eat.el (eat-term-parameters): New function.
* eat.el (eat-term-set-parameter): Handle more special
parameters: 'input-function', 'ring-bell-function',
'grab-mouse-function', 'grab-focus-events-function',
'manipulate-selection-function', 'set-title-function' and
'set-cwd-function'.
* eat.el (eat-term-input-function, eat-term-ring-bell-function)
(eat-term-set-cursor-function, eat-term-grab-mouse-function)
(eat-term-grab-focus-events-function)
(eat-term-manipulate-selection-function)
(eat-term-set-title-function, eat-term-set-cwd-function):
Remove function.
* eat.el (eat-exec, eat--eshell-setup-proc-and-term)
(eat--trace-replay-eval): Update to use parameters.
