GCPro Macro Language README

Buhler GCPro is a tool that helps engineers to program PLC with ease and embedded know-how.

GCPro functionalities can be extended by using Macros (gcmac files) which are use during compilation to achieve the expected result.

This Extension is used to help users with the macro syntax and provide a better view of the macro file.

Features

The instructions are tokenized and highlighted as it should be described on GCPro Developer Manual (normally under C:\Program Files (x86)\Gcpro\GCPRO-NET-Developer_MAN_1A_en.pdf).

Diagnostics

The extension also check some typo mistakes such as unclosed or not opened angular quotes, duplicated declaration and warn the user if there is any Breakpoints left on the opened files:

• Breakpoints:

  

• Declarations:

  

Structures check are also made to check missing statement parts:

Snippets

!!! note "CamelCase and Underscores are replaced by space on description after tab"

• function: Create function structure
• if: Create If structure
• ifelse: Create If Else structure
• ifelseif: Create If ElseIf structure
• looptree: Create LOOPTREE structure
• looptype: Create LOOPTYPE structure
• loopobj: Create LOOPOBJ structure
• loops7block: Create LOOPS7BLOCK structure
• loops7tag: Create LOOPS7TAG structure
• loopconnectors: Create LOOPCONNECTORS structure
• with: Create With structure
• while: Create While structure
• for: Create For structure
• foreach: Create ForEach structure
• property: Create Property with get and set

Commands

Commands can be found with a right click on a context of a *.gcmac file or *.scl

• Surround with Angular Quotes (shortcut: ctrl+shift+g ctrl+shift+a): Add angular quotes to the selected text.

  

!!! important "Important: If there is any at sign (@) inside the selection, it will be removed."

• Format SCL Code Indentation (shortcut: ctrl+shift+g ctrl+shift+f): Format the correct indentation for all output line that starts with a tab, skipping the other lines.

  

• Convert to SCL (shortcut: ctrl+shift+g ctrl+shift+c): Try to convert the selected text from AWL to SCL.

  

!!! important "Important: Convert to SCL It is a Beta command, that means you always have to double check the converted text. It also only handle the output string, so you may have to arrange the lines to select only output strings."

Formatting

Format gcmac files with the following rules:

• Indentation of code
• Remove trailing space from brackets
• Add space before and after assignment
