A method may include displaying an output, e.g., a figure, a data set, a symbolic expression or equation, a model, or any object with a representation that can be manipulated, e.g., a tree, a list, or a control loop, from executing program code. The method may include receiving an indication that the output has been modified through one or more manipulations, and generating code that represents modifications to the output, such that executing the code with the program code generates the output that has been modified.

Generating code based on user interactions with a user interface element in a code editor

A device may receive information that specifies a graphical scene. The graphical scene may include a coordinate axis. Data, to be plotted in the graphical scene, may be plotted with regard to the coordinate axis. The device may generate a structured plurality of objects. One or more objects, of the structured plurality of objects, may store properties that define the graphical scene. A particular object, of the one or more objects, may store properties that define one or more elements of the coordinate axis. The device may receive information identifying a modification to an element of the coordinate axis, of the one or more elements of the coordinate axis. The device may modify a property of the properties that define the one or more elements of the coordinate axis, based on the instruction, to implement the modification specified by the instruction.

Rendering graphical scenes

A device may receive an indication to evaluate a first portion of program code and a second portion of program code provided in a first section of a user interface. The device may evaluate the first portion of program code and the second portion of program code. The device may generate a first result corresponding to the first portion of program code and may generate a second result corresponding to the second portion of program code based on evaluating the first portion of program code and the second portion of program code. The device may provide the first result and the second result in a second section of the user interface. The second section may be separate from the first section. The device may provide a correspondence indicator that indicates a correspondence between the first result and the first portion of program code.

Program code interface for providing program code and corresponding results of evaluating the program code

A device may determine to provide help information associated with a portion of program code included in a program and provided via a user interface of a programming environment. The device may obtain generic help information, associated with the portion of program code, based on determining to provide the help information. The device may determine a set of rules for modifying the generic help information using the portion of program code. The device may analyze the program, using the set of rules, to identify information, included in the program, to be included in modified help information. The device may modify the generic help information, to generate the modified help information, using the information identified based on analyzing the program. The device may provide the modified help information for display via the user interface.

Using program code to generate help information, and using help information to generate program code

A device may provide a user interface that includes a first section for displaying multiple portions of program code and a second section for displaying multiple results of evaluating the multiple portions of program code. The device may detect an evaluation trigger associated with an unevaluated portion of program code of the multiple portions of program code. The device may determine one or more portions of program code to be evaluated based on detecting the evaluation trigger. The one or more portions of program code may be less than the multiple portions of program code. The device may cause the one or more portions of program code to be evaluated to generate one or more corresponding results. The device may provide the one or more corresponding results for display via the second section of the user interface.

Determining when to evaluate program code and provide results in a live evaluation programming environment

A device may receive an indication to evaluate a portion of program code. The device may cause the portion of program code to be evaluated based on receiving the indication to evaluate the portion of program code. The device may determine an intermediate result used to generate an overall result of evaluating the portion of program code based on causing the portion of program code to be evaluated. The intermediate result may be determined by evaluating a sub-portion of program code included in the portion of program code. The device may receive information that identifies a granularity level for displaying the intermediate result. The granularity level may indicate whether the intermediate result is to be provided for display. The device may selectively provide the intermediate result for display based on the granularity level.

Providing intermediate results of evaluating program code that includes a compound statement

A device may receive an indication to perform a performance evaluation on program code. The device may partition the program code into multiple program code portions based on receiving the indication to perform the performance evaluation. The device may execute a first program code portion of the multiple program code portions. The device may determine that the first program code portion has finished executing, and may determine a performance characteristic associated with execution of the first program code portion based on determining that the first program code portion has finished executing. The device may execute a second program code portion, of the multiple program code portions, and may provide information that identifies the performance characteristic while the second program code portion is being executed.

User interface driven real-time performance evaluation of program code

A device may receive an indication to evaluate a first portion of program code and a second portion of program code provided via a user interface. The first portion of program code may include an error. The device may cause the first and second portions of program code to be evaluated based on receiving the indication to evaluate the first and second portions of program code. The second portion of program code may be evaluated after the first portion of program code. The device may generate a first result corresponding to the first portion of program code and a second result corresponding to the second portion of program code. The first result may include an error indicator. The device may provide the first result and the second result via the user interface.

Programming environment for executing program code despite errors and for providing error indicators

In an embodiment, a computer-readable medium may include computer-executable instructions for dynamic symbolic math engine selection. The instructions, when executed by a processor, may cause the processor to: dynamically select a first symbolic math engine from two or more symbolic math engines; convert a first symbolic command from a standard format into a first format compatible with the first symbolic math engine; pass the first converted command to the first symbolic math engine for executing; receive an error from the first symbolic math engine from executing the first converted command; convert the first symbolic command from the standard format into a second format compatible with a second symbolic math engine based on the error received from first symbolic math engine, wherein the second symbolic math engine is selected from the two or more symbolic math engines; and pass the second converted command to the second symbolic math engine for executing.

System and method for dynamic symbolic math engine selection

In an embodiment, a computer-readable medium may include computer-executable instructions for selecting a symbolic math engine. The instructions may be executed on a processor. The medium may include: one or more instructions for dynamically selecting a first symbolic math engine from two or more symbolic math engines; one or more instructions for converting a symbolic command from a standard format into a first format compatible with the first symbolic math engine; one or more instructions for passing the converted command to the first symbolic math engine for executing, the executing including producing a result; and one or more instructions for outputting or storing the result of the executing.
