CFortranTranslator：从Fortran到C ++的翻译器.zip

# CFortranTranslator A translator from Fortran90/Fortran77(ISO/IEC 1539:1991) to C++ Fortran is an efficient tool in scientific calculation. However sometimes translating old fortran codes to C++ will enable more programming abstraction, better GUI framework support, higher performance IDE and easier interaction. This translator is not intended to improve existing codes, but to make convenience for those who need features of C++ and remain fortran traits and performance as much as possible. [](https://travis-ci.org/CalvinNeo/CFortranTranslator) [](https://coveralls.io/github/CalvinNeo/CFortranTranslator?branch=master) ## Features 1. Convert Fortran90/Fortran77 code to C++14 2. Parse codes mixed with fixed form and free form automaticlly 3. C++ implemetation of some Fortran's type and functions 4. Generated C++ code remains abstract level of the origin code e.g. implied-do will not expand to a for-loop directly, but to a `ImpliedDo` struct ## License The whole project, including both the translator itself and fortran standrad library implementation is distributed under GNU GENERAL PUBLIC LICENSE Version 2 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Calvin Neo Copyright (C) 2016 Calvin Neo This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

MSVC(e.g. Visual Studio 2015) 2. win\_flex(win\_flex\_bison 2.4.5, flex 2.5.37) 3. win\_bison(win\_flex\_bison 2.4.5, bison 2.7) 4. boost(1.60) ### Configure boost - build boost ``` bjam --toolset=msvc-14.0 address-model=64 ``` - configure boost 1. Add **boost\_dir** directory to additional include library 2. Add **boost\_dir/libs** and **boost\_dir/stage/lib** to additional library directory ### Configure winflex and winbison 1. On the Project menu, choose Project Dependencies. 2. Select Custom Build Tools 3. Add [/src/grammar/custom\_build\_rules/win\_flex\_bison\_custom\_build.props](/src/grammar/custom\_build\_rules/win\_flex\_bison\_custom\_build.props) ### Build by MSBuild Run [/build/vcbuild.cmd](/build/vcbuild.cmd) You can get Visual C++ Build Tools [here(Not available now)](http://landinghub.visualstudio.com/visual-cpp-build-tools) or [here](https://visualstudio.microsoft.com/zh-hans/downloads/) All built production will be in [/bin](/bin) ### Build by NMake Run [/build/winmake.cmd](/build/winmake.cmd) to get a x64 Release binary ### Build By Visual Studio Open [/vsbuild/CFortranTranslator.sln](/vsbuild/CFortranTranslator.sln) ## Build project in Ubuntu ### Dependencies 1. g++(e.g. g++ 5.4.0) 2. bison 3. boost ### Configure boost Install boost by sudo apt-get install libboost-all-dev ### Configure bison Install bison by sudo apt-get install bison ### Make cd build && make make install ## Fortran standard library(for90std) **for90std** is a simple implementation of fortran's library and is yet to be done for90std requires compiler support at least C++14 standard(with several C++17 std functions) With the following statement to include for90std module #include "for90std/for90std.h" ### cpptest [cpptest](/cpptest) is a C++ project template for you to test for90std. ## Run CFortranTranslator with arguments -f file_name : translate file_name into C++ **Currently, Unicode encoding is not supported** -d : use debug mode -C : use c-style array -F 90/77 : specify Fortran standard, by default the translator accept a mixed Fortran77/90 codes # Demo ## The "hello world" demo 1. Use the following command to generate target C++ code ``` CFortranTranslator.exe -Ff demos/helloworld.f90 > target.cpp ``` 2. Build *target.cpp*, modify `#include "../for90std/for90std.h"` to ensure you include the right path of for90std library. You can either use [/cpptest/winmake.cmd](/cpptest/winmake.cmd) to build your code, or build them in cpptest project. ## More demos ### Translator Demos Several demos are provided in [/demos](/demos). Run [/demos/merge_test.py](/demos/merge_test.py) to generate a `*.form.test` file by merging codes from all `.for`/`.f90` files in a certain folder. Then you can convert the merged Fortran code into C++. ### for90std Demos Several demos are provided in [/demos/for90std](/demos/for90std). Make sure you have google-test library before test. # Debug Only fatal errors hindering parsing will be reported by translator. Debuging origin fortran code or generated C++ code is recommended. # Docs see [/docs/brief.md](/docs/brief.md) ## Develop details guide see [/docs/Develop.md](/docs/Develop.md) to have an general understanding of implementation of this project.
