Christian Muehlhaeuser 44f17fa1c0 fix: stop renderer before acquiring renderer mutex 2023-06-05 10:05:38 +02:00
Christian Muehlhaeuser 402d2b4e2b fix: stop renderer before launching a child process.
Stops the renderer before starting a child process, which prevents
the repaint race condition that writes to non-altscreen.

Christian Muehlhaeuser a136799ed3 fix: renderer only stops once
Ensure the tea renderer can be stopped and restarted more than once.

Christian Muehlhaeuser 0f1ce7f2d9 fix: maintain cursor visibility across altscreen state switch
Based on #462 and #452 by @londek, but fixes maintaining the
current visibility state across altscreen state changes.

This makes the behavior consistent across terminals, some of which
keep separate state for altscreen and regular buffer.

Fixes #190.

Christian Muehlhaeuser a7067fbfa2 fix: prevent renderer from overflowing available height
Drops lines from the top when the render buffer is taller than the
available height.

Fixes #297.

Christian Muehlhaeuser db664820d4 fix: lock mutex before checking altscreen state
This prevents the odd race condition where Enter- & ExitAltScreen
are called concurrently.

feat: print unmanaged output above the application (#249)
* merge Adjective-Object/tea_log_renderer into standard renderer

* rename queuedMessages -> queuedMessageLines & break apart strings during message processing

* delete cursorDownBy

* += 1 -> ++ to make the linter happy

* add skipLines[] tracking back to standard renderer, and add rename skippedLines local to jumpedLines to clarify they are separate comments

* request repaint when a message is recieved

* Convert Println and Printf to commands

* Add package manager example demonstrating tea.Printf

* Use Unix instead of UnixMicro for Go 1.13 support in CI

* fix off by one in std renderer

* add Printf/Println to tea.go

* revert attempt at sequence compression + cursorUpBy

Georgi Dimitrov 958dc20024 fix: race condition on repaint with alt screen
I didn't realise at the time, but the tea.Program and the renderer share
the mutex. This make the code difficult to reason about - it turns out
the program sometimes acquires the lock and then calls the
`setAltScreen` method of the renderer which in turns calls `repaint`.
That causes a deadlock as `repaint` is trying to acquire the lock too.

Christian Rocha 119144e78c ANSI compression is now opt-in via the WithANSICompressor program option 2021-10-30 13:04:27 -04:00
Christian Muehlhaeuser c29912c179 Enable ANSI compressor
With this change all ANSI output will be piped through an ANSI compressor that
eliminates redundant ANSI sequences. As such the compressor can be considered
"lossless".

Christian Rocha 1f773e8f20 Fix a race where artifacts could print when exiting a program
This commit also consolidates the exit operations for consistency's
sake, and adds a kill() method to renderers for stopping them without
performing any final rendering.

Christian Rocha 3256fae4d4 Force a full repaint when resizing the window
v0.13.4 introduced a regression where lines weren't always cleared when
resizing the window resulting in the presence of rendering artifacts.
This commit fixes that.

Christian Rocha 70be13948a Re-render all lines if the total number of lines increases
If the number of lines increased there's a chance that the increase in
lines caused the terminal to scroll (even in the altscreen). Because of
this we must repaint everything, as skipping lines will mis-render.

Thanks to @fiws for reporting this bug.

ProgramOption WithoutRenderer.
