Errors

Stores information useful for creating the layout of a stack trace visualization.

add_new_module_name!(content, ctx::StacktraceContext, curr_modul)

When a frame belonging to a module different from the previous one is shown, print the new module's name.

add_number_frames_skipped!(content, ctx, to_skip, num, bt, n_skipped, skipped_frames_modules)

Add some text explaining how many frames were skipped from the stacktrace visualization and to which modules they belonged.

function add_stack_frame! end

Create a Term visualization of info and metadata about a stacktrace frame.

add_stack_frame!(frame::StackFrame, ctx::StacktraceContext, num::Int;  kwargs...)

Renders a panel with:

• frame number
• function name/signature
• source code at error line

function frame_module end

Get the Module a function is defined in, as a string

Get module for a pointer obj

Get module from file path.

get_frame_function_name

Get and stylize a function's name/signature

install_term_stacktrace(; reverse_backtrace::Bool = true, max_n_frames::Int = 30)

Replace the default Julia stacktrace error stacktrace printing with Term's.

Term parses a StackTrace adding additional info and style before printing it out to the user. The printed output consists of two parts: - a list of "frames": nested code points showing where the error occurred, the "Error Stack" - a message: generally the standard info message given by Julia but with addintional formatting option.

Several options are provided to reverse the order in which the frames are shown (compared to Julia's default ordering), hide extra frames when a large number is in the trace (e.g. Stack Overflow error) and hide Base and standard libraries error information (i.e. when a frame is in a module belonging to those.)

parse_kw_func_name(frame::StackFrame)

Kw function calls have a weird name, parse arguments to get a proper function signature.

render_backtrace(bt::Vector; reverse_backtrace = true, max_n_frames = 30)

Main error backtrace rendering function. It renders each frame in a stacktrace after some filtering (e.g. to hide frames in BASE). It takes care of hiding frames when there's a large number of them.

render_error_code_line(frame::StackFrame; δ=2)

Create a Panel showing formatted Julia code for a frame's error line. The parameter δ speciies how many lines above/below the error line to show.

should_skip

A frame should skip if it's in Base or an installed package.
