Package: lowbar
lowbarThe simplest no-nonsense progress bar for python.lowbar is a blazing fast module with zero dependencies for displaying a progress bar in the terminal. It has a low number of features and a simple codebase, hence the name lowbar.lowbar has:Automatic resizingManual progress managementAutomatic progress management (As an iterable)Text loggingBar customizationExtremely low overheadSmall package sizelowbar doesn't have:Nested barsFancy animationsETA calculationsRequirementsPython 3.7 or above. lowbar may support earlier versions, but this has not been tested.A console that supports line feed\nand carriage return\r.InstallationInstall the latest stable release:pip install lowbarOr the development version:pip install git+https://github.com/AnnikaV9/lowbarUsageOnce you have lowbar installed, you can import it like any other module:importlowbarAnd initialize the bar:bar=lowbar.lowbar()To make the bar visible and set at 0%:bar.new()After completing some tasks, we can increase the bar's completion percentage:bar.update(20)The above function will immediately move the bar to 20%. To use a more smoother but slower animation:bar.update_smooth(40)Note:Since version 1.1.4,update_smooth()is no-longer fully blocking. It will run in a separate thread, so your program will continue it's execution while the bar is animating. However, calling another lowbar function during the animation will block the main thread to prevent visual glitches. To avoid this block, make sure to calllog()beforeupdate_smooth(), not after. See issue#5Usingprint()or other similar functions will push the bar up, which doesn't look nice. To log messages without affecting the bar:bar.log("Hello World!")And finally, to clear the bar completely:bar.clear()Here's an example usage of the bar:bar=lowbar.lowbar()completion=0bar.new()foriinrange(10):time.sleep(2)# This would be replaced with an actual taskbar.log(f"Task{i+1}completed")completion+=10bar.update_smooth(completion)bar.clear()print("Tasks complete!")You don't even need a loop:bar=lowbar.lowbar()bar.new()time.sleep(1)bar.update_smooth(10)time.sleep(2)bar.update_smooth(40)time.sleep(2)bar.update_smooth(100)bar.clear()print("Tasks complete!")The bar can also be used with a context manager. It will automatically runnew()at the start andclear()when exiting:withlowbar.lowbar()asbar:time.sleep(1)bar.update_smooth(10)time.sleep(3)bar.update_smooth(100)print("Tasks complete!")To make things simpler, you can wrap lowbar aroundrange()and turn it into an iterable. It will automatically calculate how much to increase the percentage by every loop:foriinlowbar.lowbar(range(100)):time.sleep(0.5)To make things even more simpler, you can pass an integer and lowbar will convert it into a range object for you:foriinlowbar.lowbar(100):time.sleep(0.5)lowbar will useupdate()by default when used as an iterable. If you're only going to loop a few times, you can force lowbar to useupdate_smooth():foriinlowbar.lowbar(6,smooth_iter=True):time.sleep(1)Note:You can't uselog()when using lowbar as an iterable.You can also change the load fill and blank fill chars:bar=lowbar.lowbar(bar_load_fill="O",bar_blank_fill=".")Or add a description text to the left side of the bar:bar=lowbar.lowbar(bar_desc="Downloading...")Note:If the console is too small to accommodate both the bar and the description text, the text will be hidden.Parameters__init__()-   Init function thats called when the lowbar object is created.bar_iter: A range object that lowbar will iterate through when__iter__()is called. If an integer is provided, lowbar will automatically convert it into a range object. Default:0smooth_iter: A boolean switch which forces lowbar to useupdate_smooth()when iterating. Default:Falsebar_load_fill: A string of size 1, which will be used to fill the bar as it loads. Default:"#"bar_blank_fill: A string of size 1, which will be used to fill the part of the bar that isn't loaded yet. Default:"-"bar_desc: A string, which will be displayed to the left of the bar. If the console is too small to accommodate both the bar and the desc, the desc will be hidden. Default:""remove_ends: A boolean switch which will hide the chars placed at both ends of the bar ([&]). Default:Falseno_clear: A boolean switch which will stop lowbar from clearing the bar automatically when used as an iterable or with a context manager. Useful if you want a 'receipt'. Default:Falsenew()-   Alias forupdate(0)update()-   Increases or decreases the completed percentage and refreshes the bar, automatically resizing if the console size has changed.percentage: An integer value to set the completed percentage as. No default value.update_smooth()-   Same asupdate(), with a smoother but slower animation. Avoid using this function if execution speed is important for you. The completion percentage cannot be decreased with this function.percentage: An integer value to set the completed percentage as. Must be higher than the currently set value. No default value.log()-   Logs text to the console without affecting the bar.text: Any string. Any other type needs to be converted withstr()before being passed to this function. No default value.clear()-   Clears the currently running bar.ContributingAll contributions are welcome!If you wish to report a bug or suggest a feature, open anissue.You can also make apull requestdirectly if you already have the fix for a bug.SeeCONTRIBUTING.mdfor guidelines to follow.Contributors are listed inCONTRIBUTORS.md.LicenseMIT License
