preprocessor

This is my first time doing anything with XSLT, or XML really, so please excuse me. I've found XSLT web documentation is really terse. I have an XML file that I want to process to selectively drop content based on an input set of defines. The behavior should be similar to a simple code pre-processor handling ifdef blocks. I've worked out how to do it as below, but some parts such as the "contents" variable didn't seem like the best way to handle this. <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" /> <xsl:param name="defines-uri"

I would like to understand how the preprocessor inlines includes into the code in Fortran. With C, it's pretty simple: Test.c: #include <stdio.h> int main(void) { return 0; } Then I compile using: gcc -E test.c Then it displays the content generated by the C preprocessor, as expected. Now assume I have this Fortran code: Test.f: program test include "mpif.h" call mpi_init call mpi_finalize end Then I run: gfortran -E -cpp test.f // For some reason I need -cpp when using -E in Fortran But I won't have the expected result, which is the generated include embedded into the code. Instead, I have

In C++ I'd write bool positive (int a) { #ifdef DEBUG cout << "Checking the number " << a << "\n"; #endif return a > 0; } In OCaml I could write let positive x = begin printf "Checking the number %d\n" x; x > 0 end But how can I disable the printf statement when not in debug mode? you can use cppo : https://github.com/mjambon/cppo . This is available via opam, and offers C like preprocessor features. Without preprocessing you can simply have a global flag defined as let debug = true and write: if debug then printf ...; This code is removed by ocamlopt if debug is false. That said, it's

I am looking for some preprocessor functionality in nasm that would allow having one source code for both x86 and x64 architectures. I mean something in the vein of ifdef some_constant. Like C preprocessor uses if it wants to detect say if it's compiled on Windows or Linux. Edit I know about nasm flags. I use them. I just want to have the very same source code and expect preprocessor to handle it correctly based on those flags. I'd use ifdef ... else for stack operations and so one, having the core code same for both architectures. NASM cannot detect the architecture, but you can use the

Was trying to understand the difference between a syntax that would include another script file and a source file in Inno Setup script while using macros to search and find files. I have tried to use FindFolder function from Find a directory using wildcard in Inno Setup : #define FindFolder(Path) \ Local[0] = FindFirst(Path, faDirectory), \ Local[0] ? AddBackslash(ExtractFileDir(Path)) + FindGetFileName(Local[0]) : Path Like this: #include "{#FindFolder('..\..\..\packages\ScriptPreRequisites*')}\DotNetDependencies.iss" Within # you are in the "realm" of Inno Setup preprocessor . There are two
