Descripción
Compile project allows you to compile the current host project or the project specified in the projectFile parameter. For more information on compilation, check the Compilation page.
By default, the command uses the compiler options defined in the Structure Settings. You can override them by passing an options parameter. Se soportan las siguientes sintaxis:
- Compile project(): compiles the opened project using the options defined in the Structure Settings
- Compile project(options): compiles the opened project. The options defined override the Structure Settings
- Compile project(projectFile): compiles the projectFile 4DProject using the options defined in the Structure Settings
- Compile project(projectFile; options): compiles the projectFile 4DProject and the options defined override the Structure Settings
Note: Binary databases cannot be compiled using this command.
Unlike the Compiler window, this command requires that you explicitly designate the component(s) to compile. When compiling a project with Compile project, you need to declare its components using the components property of the options parameter. Keep in mind that the components must already be compiled (binary components are supported).
The resulting compiled code will be stored in the DerivedData or Libraries folder of the project, depending on the targets property of the options parameter. If you want to create .4dz files, you still need to manually zip the compiled project or use the build application feature.
If you pass an empty collection in targets, Compile project will execute a syntax check without compiling.
Compilation errors, if any, are returned as objects in the errors collection.
Note: You cannot call this command when another compilation is running (for example, a compilation launched from the Compilation window).
options Parameter
The options parameter is an object. Here are the available compilation options:
| Propiedad | Tipo | Description |
|---|---|---|
| components | Collection | Collection of 4D.File objects to dependent components (must be already compiled) |
| defaultTypeForButtons | Integer | Possible value: Is real or Is longint |
| defaultTypeForNumerics | Integer | Possible value: Is real or Is longint |
| generateSymbols | Boolean | True to generate symbol information in the .symbols returned object |
| generateSyntaxFile | Boolean | True to generate a syntax file for code completion.md#generate-syntax-file-for-code-completion-when-compiled) in the \Resources\en.lproj folder of the project |
| generateTypingMethods | Text | "reset" or "append" to generate typing methods. If value is "append", existing variable declarations won't be modified (compiler window behavior). If value is "reset" existing variable declarations are removed beforehand. |
| plugins | Objeto 4D.Folder | Plug-ins folder to be used instead of the Plugins folder of the current project. This property is only available with the projectFile syntax. |
| targets | Colección de cadenas | Possible values: "x86_64_generic", "arm64_macOS_lib". Pass an empty collection to execute syntax check only |
| typeInference | Text | "all": The compiler deduces the types of all variables not explicitly declared, "locals": The compiler deduces the types of local variables not explicitly declared, "none": All variables must be explicitly declared in the code (legacy mode), "direct": All variables must be explicitly declared in the code (direct typing). |
| warnings | Colección de objetos | Defines the warnings state |
| [].major | Number | Warning main number, before the dot |
| [].minor | Number | Warning second number, after the dot |
| [].enabled | Boolean | Warning activation state |
Note: When the warnings attribute is not defined in the options object, the Compile project command uses the default warning generation statuses defined in the settings.
Resultado
The object returned by Compile project has up to three properties:
| Propiedad | Tipo | Description |
|---|---|---|
| success | Boolean | True si la acción guardar tiene éxito, false en caso contrario. |
| errors | Colección de objetos | Available only in case of error or warning. Collection of objects describing compilation errors or warnings |
| [].isError | Boolean | Error if True, warning otherwise |
| [].message | Text | Mensaje de error |
| [].code | Object | objeto código |
| [].line | Number | Line number of error in the code. For class methods, line number in the function |
| [].lineInFile | Number | Line number in the file (different from "line" for class methods, and takes into account the %attributes prefix line) |
| symbols | Object | Available only if generateSymbols option is set to True: |
| symbols.interprocessVariables | Object | List of all interprocess variables |
| symbols.interprocessVariables.variables | Collection | Colección de objetos variables |
| symbols.interprocessVariables.size | Number | |
| symbols.processVariables | Object | List of all process variables |
| symbols.processVariables.variables | Collection | Colección de objetos variables |
| symbols.processVariables.size | Number | |
| symbols.localVariables | Colección de objetos | List of local variables per method |
| symbols.localVariables[].code | Object | objeto código |
| symbols.localVariables[].variables | Collection | Colección de objetos variables |
| symbols.methods | Colección de objetos | Lista de métodos |
| symbols.methods[].code | Object | objeto código |
| symbols.methods[].callCount | Number | Number of times this method has been called |
| symbols.methods[].params | Collection | Collection of parameter types (Value type numerical codes) |
| symbols.methods[]. threadSafe | Boolean | Indicates if this method is thread safe |
For more information, see Compilation tools.
variable objects
interprocessVariables.variables and processVariables.variables contain objects with the following structure:
| Propiedad | Tipo | Descripción |
|---|---|---|
| name | Text | Name of the variable |
| type | number | Type of the variable (like Value type command) |
| arrayDimension | number | For arrays only: 1 for mono dimension arrays, 2 for two-dimension arrays |
| code | Object | For process and interprocess variables: descriptor of where the variable has been defined |
code object
The code property in methods.code and errors.code is an object with the following properties:
| Propiedad | Tipo | Description |
|---|---|---|
| type | Text | "projectMethod", "formObjectMethod", "formMethod", "databaseMethod", "triggerMethod", "executeOnServer" (when calling a project method with the Execute on Server attribute), "executeFormula" (when executing a formula via PROCESS 4D TAGS or evaluation of a formula in a 4D Write Pro document), "class", "classFunction", "formObjectExpression" (for errors occuring in expressions associated to form objects) |
| path | Text | Method path (same format as METHOD OPEN PATH) |
| file | 4D.File | Method file |
Returned depending on the value of the type property: | ||
| methodName | Text | Métodos proyecto |
| tabla | Number | Number of the table (returned for a trigger, a table form method or a table form object method) |
| formName | Text | Form name (returned for a form method) |
| objectName | Text | Form object name (returned for an object method) |
| propertyName | Text | Form object property name (returned for a form object expression) |
| className | Text | Class name |
| functionName | Text | Nombre de la función de clase |
| databaseMethod | Number | Database method index |
Ejemplos
To perform a syntax check only, pass an empty collection to the targets parameter:
var $status : Object
var $options:={}
$options.targets:=New collection //Empty collection for syntax checking
$status:=Compile project($options)
Compile the current project using the compiler options of the Structure Settings only:
var $status : Object
$status:=Compile project
On a Silicon Mac, compile the current project to ARM only:
var $status : Object
var $options:={}
$options.targets:=New collection("arm64_macOS_lib")
$status:=Compile project($options)
Compile a project other than the current project:
var $status : Object
var $projectFile: 4D.File
$projectFile:=Folder(fk documents folder).file("Databases/myApp/Project/myApp.4DProject")
$status:=Compile project($projectFile)
Compile a project and declare its component:
var $status : Object
var $component : 4D.File
var $options:={}
$component:=Folder(fk documents folder).file("Components/myComponent.4dz")
$options.components:=New collection($component)
$status:=Compile project($options)
Disable warnings 518.1 and 518.2 when compiling your project:
var $options:={}
$options.warnings:=[]$options.warnings.push({major: 518; minor: 1; enabled: False})
$options.warnings.push({major: 518; minor: 2; enabled: False})
var $result:=Compile project($options)
