Conditional compilation syntax
f#compiler

I am looking at the F# manual for the syntax on conditional compilation. Here is what I have typed.

1
2
3
4

#if <DEBUG>  // Syntax error
#r "NUnit.Core.dll";;
#r "NUnit.Framework.dll";;
#endif

I am getting a syntax error. I have added --define DEBUG to the command line. I am using the latest compiler 1.1.11.12.

Am I doing something wrong?

Thanks in advance. Regards

Chris

.

Just use

1

#if DEBUG

We'll add an example to the manual

Cheers!

Don,

Thanks for the reply. A few questions though.

1) The syntax highlighting does not appear in the lines between #if and #endif (that is why I was not sure whether or not I was doing the correct thing.) For example, if I use --define DEBUG in the command line, and the following in my code

1
2
3

#if DEBUG
#r "NUnit.Framework.dll";;
#endif

if the dll is not found, it will produce an error. Other than that, I have no way of knowing whether the code is being included or not. Is this correct?

2) Is there an #else command in F#? Usually I like to include one set of dll for my debugging code and another set for my runtime code. I can easily work around the problem though.

Thanks.

Regards

Chris

Hi Chris,

You are right - alas, alas the lexing highlighting is not yet sensitive to #defines. We'll look into fixing that, or at least providing some workaround.

Yes, there is a #else. Some issues with nested #if/#else were fixed in the latest release.

Cheers!

Hello is there a way to make a #define in the source code itself? and with a value like for example "#define CONSTANT 2" ?
