Genie’s public methods of programme management

Page in progress.
An example of creating a simple application using the Genie framework is also provided at Community Engee.

All public genie program control methods for working with the Genie framework are presented here.

genie methods

engee.genie.start(app_path::String; devel::Bool=false, log_file::String="")

Launches the Genie application at the specified path.

Before using the engee.genie.start command, make sure that if the application is a directory, it contains a file with the application code and the .jl extension. Also remove the config and *.toml files (if present).

Arguments

  • app_path::String: path to the application directory. Can be relative or absolute.

  • devel::Bool=false: parameter to enable development mode, where code changes are applied without restarting the application.

  • log_file::String="": parameter to specify the path to the log file. If not specified, the logs are not saved separately.

Examples

# Запуск Genie через файл приложения app.jl, без режима разработки и сохранения логов
engee.genie.start("/user/app.jl")

# Запуск Genie через файл приложения app.jl, с режимом разработки и сохранением логов
engee.genie.start("/user/app.jl", devel=true, log_file="/user/logs.txt")
engee.genie.stop(app_path::String)

Stops the running Genie application.

Arguments

app_path::String: path to the application directory. Can be relative or absolute.

Examples

# Остановка приложения по абсолютному пути
engee.genie.stop("/user/app.jl")

# Остановка приложения по относительному пути
engee.genie.stop("app.jl")
engee.genie.list()

Displays a list of all running Genie applications.

Examples

engee.genie.list()
engee.genie.eval(code::AbstractString)

Executes the specified code in Engee workspace outside the context of a running Genie application. Use to run individual expressions, debug or dynamically execute code without having to restart the application.

Arguments

code::AbstractString: string with the code on Julia to be executed in the Engee workspace.

Examples

engee.genie.eval("x = 5")
engee.genie.recv(wsVarName::AbstractString; context::Module=GenieAPI )

Returns the value of a variable from the specified context (module) in the Engee workspace at runtime of the Genie application.

By default, the variable is looked up in the module GenieAPI, but if necessary, you can explicitly specify another module via the parameter context. Thus, if the variable is defined in another module, the parameter context is used to specify in which namespace to look for it.

Arguments

  • wsVarName::AbstractString: the name of the variable whose value is to be retrieved.

  • context::Module=GenieAPI: the module in which the variable is searched. Specified explicitly if the variable does not belong to module GenieAPI.

Examples

# Получение значения переменной x из модуля Main
engee.genie.recv("x", Main)

# Получение значения переменной a из модуля по умолчанию
engee.genie.recv("a")

# Получение значения переменной value из пользовательского модуля
engee.genie.recv("value"; context=MyModule)
engee.genie.send(wsVarName::AbstractString, value::Any)

Saves the value of value to the wsVarName variable in the Engee workspace while the application is running on Genie.

If a variable with this name did not exist before, it will be created automatically. The function is useful for passing intermediate results or user data from the Genie application to a Engee session.

Arguments

  • wsVarName::AbstractString: the name of the variable to which the value is assigned.

  • value::Any: the value to be stored in the variable. Can be of any type.

Examples

# Присвоение переменной x значение 124
engee.genie.send("x", 124)

# Сохранение строки в переменной message
engee.genie.send("message", "Hello")
