ABAP In Emacs (AiE)

Introduction

This project implements a Emacs plugin which allows to access development artifacts like reports, classes, interfaces etc. of a ABAP system. It uses the ABAP Development Tools (ADT) HTTP protocol to access the ABAP workbench functionality. Currently, the package provides the following:

• Retrieve (Pull) source from ABAP server
• Offline edit
  To have ABAP Mode available, a major mode for editing/viewing development files in Emacs, install sap-abap-mode (see description below).
• Server side formating & auto-complete
• Server side syntax check
• Submit (push) source to ABAP server
• Activate source at ABAP server
• Run source

Installation

The current version can only be installed manually. Clone this repository with the --recursive option, i.e.

$ git clone --recursive https://github.com/marianpiatkowski/ABAPInEmacs.git

to get additional packages like sap-abap-mode as well. Add ABAPInEmacs directory to your load-path

(add-to-list 'load-path "path/to/ABAPInEmacs")
;; sap-abap-mode includes
(require 'abap-mode)
(add-to-list 'auto-mode-alist '("\\.abap\\'" . abap-mode))
;; ABAP CDS Mode
(require 'abap-cds-mode)
(add-to-list 'auto-mode-alist '("\\.cds\\'" . abap-cds-mode))
(require 'abap-ddic-mode)
(add-to-list 'auto-mode-alist '("\\.tabl\\'" . abap-ddic-mode))
;; ADT files as well
(add-to-list 'auto-mode-alist '("\\.\\(asprog\\|asinc\\|aclass\\)\\'" . abap-mode))
(add-to-list 'auto-mode-alist '("\\.asddls\\'" . abap-cds-mode))
(add-to-list 'auto-mode-alist '("\\.astabldt\\'" . abap-ddic-mode))
;; ABAPInEmacs includes
(require 'abap)
(require 'abap-flycheck)

Specify your workspace directory by setting the variable abap-workspace-dir.

(setq abap-workspace-dir "path/to/ABAPWorkspace")

With the configuration above

• ABAP Mode will be loaded automatically once a file with suffix .abap has been opened
• ABAP CDS Mode will be loaded automatically once a file with suffix .cds has been opened
• ABAP DDIC Mode will be loaded automatically once a file with suffix .tabl has been opened.

Usage

Project setup

Steps to set up a ABAP project:

• Create a project with M-x abap-create-project.
  If you already have a project, it can be added with M-x abap-add-project.
  Remove an existing project with M-x abap-remove-project. This will not physically remove the project files.
  At any time, you can open or switch to an existing project with M-x abap-open-project.
• Add a ABAP server to project with M-x abap-add-server.

Start development

The following steps are an essential part of the workflow:

1. M-x abap-login - Logon to ABAP server
   By default, the encoded credential will be persisted so that a login on each action is not required.
2. M-x abap-search-object - Search ABAP development object
   The source code of the selected search result is then pulled from the ABAP server and a directory buffer opens up showing the corresponding files.

Once a ABAP development object has been successfully fetched by Step 2, the following steps can be done when working on .abap-files:

3. M-x abap-retrieve-source - Get content of ABAP development object associated to current buffer from server

4. M-x abap-check-source-uptodate - Check whether source in current buffer is up to date with server

5. M-x abap-syntax-check - Perform syntax check of object in current buffer
   If errors and/or warnings occur, they are displayed in the *ABAP Log* buffer.

   Furthermore, on-the-fly syntax checking of the source code can be enabled with the Flycheck extension for ABAP. Call M-x flycheck-abap-setup for setting this up. Documentation of the Flycheck extension can be found at the following link.

6. M-x abap-format-source - Do source code formatting of object (pretty print)

7. M-x abap-submit-source - Submit local content in current buffer to ABAP server
   Unless the object is local on the server side, a transport request has to be chosen for the current version of the source code.

8. M-x abap-activate-source - Activate (compile) object in current buffer on the server

9. M-x abap-code-completion - Request proposals for code completion from ABAP server

10. M-x abap-navigate-code - Navigate to object under cursor in current buffer, i.e. find definition/implementation of the object

11. M-x abap-execute-object - Execute source code of current buffer and display in external window. M-x abap-console-run - Execute source code of current buffer and display in *ABAP Console* buffer.

You can also create a Git repository with the retrieved source code and collaborate with other colleagues.
