Configuration

Additionally a toolchain is required, which is installed after the installation of the extension (user prompt). The language server, debug adapter and compiler are all part of the toolchain.

In order to boost your language server experience the following settings are recommended:

"kestudiocode.iec.lsp.codeLens.onLocalVariables": true,
"kestudiocode.iec.lsp.launch.autoRestart": true,
"kestudiocode.iec.lsp.launch.notifyOnCrash": true,
"kestudiocode.iec.lsp.developer.emitQueryDbBlocked": true

Semantic highlighting is enabled by default (depending on the configured theme). If you are not a fan, you can turn it off with the global setting:

"editor.semanticHighlighting.enabled": false

Set the following if you do not want kils to offer any kind of code snippets, like variable declarations, statements, blocks or type declarations, ...

"kestudiocode.iec.lsp.completion.enableSnippetInsertion": false
