Re: Can't use my macro in fuction definition

Macros also allow you to create a dsl to make your code easier to use or understand by obfuscating away bits. For example a macro that times a function call by proxying the call or wrapping a call to defn. That said, I consider many uses of macros that I’ve seen to be antipatterns that lead to

Re: Can't use my macro in fuction definition

Macros manipulate program symbols. Macros fill the role that is filled by Perl scripts in the Java world, when they pre-process stuff (a database schema, or a gui model, for example) into actual Java code before you compile it. If a task could not be solved by pre-processing the source code b

Re: Can't use my macro in fuction definition

Hey Ru, Renaming x to anything will result in roughly the same error in your function. The problem is that your instance macro needs to know the classname at compile time. As x is a runtime variable, the compiler cannot see the literal value of x at compile time. Put another way, in your test f

Re: Can't use my macro in fuction definition

Ok, Matching Socks. On what name should I replace the variable name "x" in the function definition so that the macro like it? суббота, 19 октября 2019 г., 14:09:01 UTC+3 пользователь Matching Socks написал: > > The macro is a code generator, with which the compiler computes the actual > defin

Re: Can't use my macro in fuction definition

The macro is a code generator, with which the compiler computes the actual definition of the "test" function. What's there is x, and the macro does not like x. The REPL definition of JLabel worked because JLabel was the literal argument. See https://clojure.org/reference/macros, which is sub
