Atom is a multiple platform text editor available from:

https://atom.io

Atom supports converting TextMate language bundles into language support packages. The conversion process is described at:

https://atom.io/docs/latest/converting-a-text-mate-bundle

The following shell commands can be used:

$ apm init --package ~/.atom/packages/language-logtalk --convert $LOGTALKHOME/coding/textmate2/Logtalk.tmbundle
$ sed -i.bak "s/0.0.0/$(sed -e 's/-.*$//' < $LOGTALKUSER/VERSION.txt)/" ~/.atom/packages/language-logtalk/package.json

If the apm command is not available, you can install it by selecting Atom's menu option `Install Shell Commands`.

In alternative, a third-party maintained converted bundle is readily available from:

https://atom.io/packages/language-logtalk

Several Atom packages can be useful for Logtalk development. Those include:

1. process-palette The provided process-palette.json file defines commands for compiling a file from within Atom allowing clicking on warnings and errors and jump to their location, for running unit tests, for scanning for dead code, for generating HTML documentation, and for generating SVG diagrams.

   In most cases, the menu options should be used with with either your loader file or tester file selected. This ensures that the full code of your application is loaded to perform the requested menu option.

   For using these commands, install the process-palette package and replace or merge the contents of the file with default file found at `~/.atom`. If no `~/.atom/process-palette.json` file exists just copy the provided file to `~/.atom`. Customization of this file is usually required to select your preferred Prolog backend and keyboard shortcuts. The package settings may also need to be edited to select the shell to be use (notably, on Windows, a Bash shell must be specified; e.g. the Bash shell provided by Git for Windows).

2. atom-ctags By installing this package and the Logtalk ctags support (see `../ctags`), it is possible to use Atom's `Command Palette` to index and browse Logtalk code (e.g. to search and navigate to entity and predicate declarations).
3. atom-html-preview One of the packages that allows convenient rendering of HTML and SVG files, including those generated for API documentation of Logtalk code.
4. graphviz-preview For visualizing the `.dot` files generated by the diagrams tool.
5. svg-preview For visualizing the `.svg` files generated by the diagrams tool.
6. file-icons For displaying file icons, including for Logtalk source files, in the tabs and the tree-view.

   Logtalk source files (including the library entities and the programming examples) are indented using tabs and are expected to remain perfectly indented no matter your tab width preference (a common setting is a tab width equivalent to 4 spaces).
