Matlab, Mathematica, Sage and now SymPy.Fortran (of Formula Translating) first appeared in research when IBM mainframes became available on college campuses and research centers in the 1960s. But in the context of an editor, the JDT compiler is basically performing the exact same role.Which compiler is needed for Java programming? A "smart" LaTeX editor would need an editor. JDT has a "background editor" if you will (actually an editor and a background compiler working together). I hope my explanation above demonstrates that there is no difference. If it is surprisingly the case, what is the intrinsic differenceīetween Java and TeX which makes this difference? Specially, in the second question, in the selected answer, it has beenĬlaimed that writing such an editor means a background-running editor! But clearly it can be parsed, because we have programs that consume LaTeX. LaTeX is a lot older, it has evolved differently from programming languages, and its grammar was not designed the same way a programming language grammar would be. Java (and most programming languages) was built to have a grammar that is easy to parse, making the compiler easier to write with the side effect of making the language more programmer-friendly. This is more difficult as David Carlisle mentions because LaTeX has a more complex grammar. Some process that runs as you edit your document, checking for errors. You would need something similar to the background compiler in JDT, but not a compiler. Clearly, a LaTeX editor would not work the same as a Java editor because LaTeX has no "compiler." Java and LaTeX are just different. How would a LaTeX editor in Eclipse work? This is also how if you select a method reference you can hit F3 to go to its definition. This is how JDT can tell you "missing }": the AST is broken, and it expected a } but you did not provide one. Its purpose, in this context, is to identify regions of your code: variables, method names, class declarations, etc. In the background, as you edit Java source code, the JDT compiler is building an AST ( abstract syntax tree) that is basically a data structure that represents the partially-compiled code in memory. The two work together to provide those red squigglies (their real name is "error markers" but I prefer squigglies). JDT includes two components relevant to this question: a Java editor and a Java compiler. What does the Eclipse Java plugin (JDT) do? In fact there is an entire RCP framework for building arbitrary (non-development, even) applications. But you can do anything in Eclipse: you could even implement a database, photo editor, or video game if you wanted to. It is best-known for being a Java IDE, and the Java plugin is one of the oldest and most mature available for Eclipse. It provides frameworks which can be leveraged by plugins which run in the IDE. The first thing to ask is: what is Eclipse, exactly? What does it provide?Įclipse is an IDE. It is possible, in fact a few seconds searching brought up one example.
