Fortran 包管理器#

Here’s what’s new in fpm:

  • #507: optimize file listing

  • #511: check name used for package, executable, test, or example

  • #516: initialize allocatable strings before using in a comparison

  • #517: Fix run

  • #522: remove warnings and fix truncated help text

  • #523: Fix compilation error in ifort

工作正在进行中：

  • #525 (WIP): proposal to close #525 by generating build/.gitignore

  • #527 (WIP): Add objects for handling compiler and archiver

  • #521 (WIP): expand tabs

  • #506 (WIP): Draft: initial implementation of implicit_none

  • #498 (WIP): Draft - Compiler flags profiles

fpm 仍处于早期开发阶段，我们需要尽可能多的帮助。以下是你今天可以提供的帮助：

  • 使用它，让我们知道你的想法！阅读 fpm 打包指南 了解如何使用 fpm 构建你的包，以及 清单参考 了解你可以在 fpm.toml 文件中指定的所有内容。

  • 在 fortran-lang 网站 上浏览现有的 fpm 包

  • 浏览 开启的 issues，看看你是否可以帮助实施任何修复或功能。

  • 为 fpm 调整 Fortran 包并将其提交到 Registry。

  • 改进文档。

fpm 的短期目标是使具有依赖关系的 Fortran 包的开发和安装更容易。其长期目标是构建一个丰富且分散的 Fortran 软件包生态系统，并创建一个健康的环境，在该环境中轻松创建和发布新的开源 Fortran 项目。
