@ -99,9 +99,7 @@ DSL's has some clear advantages when being applied to a specific domain compared
A language workbench is a tool created to facilitate the development of a computer language, such as a DSL. Language workbenches also create tooling for languages defined within them, and help with the language development process in general.
Language workbenches support generating tooling for languages, as most modern computer languages are backed by some form of tooling. This tooling comes in the form of language parsing, language servers for integrated development environments, along with other tooling for using the language created within the language workbench.
One part of creating a computer language is the tooling for that language. Most modern software languages are backed by some form of tooling, one important tool for a language is the language server. This is created to allow for features such as syntax highlighting, auto completion, error checking et.al. When creating a software language, generating tooling to support this features can be done using a \emph{language workbench}~\cite{LanguageWorkbench}. The language in question is specified within the language workbench, using a grammar. That grammar is then used to generate the tooling of the language. Many such language workbenches exist, such as Langium~\cite{Langium}, Xtext~\cite{Xtext}, Jetbrains MPS, and Racket.
A language is defined in a language workbench using a grammar definition. This grammar is a formal specification of the language that describes how each language construct is composed and the structure of the language. This allows the language workbench to determine what is a valid sentence of the language. This grammar is used to create the the AST of the language, which is the basis for all the tools generated by the language workbench. Many such language workbenches exist, such as Langium~\cite{Langium}, Xtext~\cite{Xtext}, Jetbrains MPS, and Racket.
