From bfeadf8764c8fbd2b70a3f87362bae1fb7176879 Mon Sep 17 00:00:00 2001 From: Henry Schreiner Date: Fri, 2 Jun 2017 19:42:05 -0400 Subject: [PATCH] Adding a couple of extra libraries. --- README.md | 32 ++++++++++++++++++++++---------- 1 file changed, 22 insertions(+), 10 deletions(-) diff --git a/README.md b/README.md index 655dd3d5..533b23ee 100644 --- a/README.md +++ b/README.md @@ -33,14 +33,23 @@ An acceptable CLI parser library should be all of the following: The major CLI parsers for C++ include (with my biased opinions): -* [Boost Program Options]: A great library if you already depend on Boost, but its pre-C++11 syntax is really odd and setting up the correct call in the main function is poorly documented (and is nearly a page of code). A simple wrapper for the Boost library was originally developed, but was discarded as CLI11 became more powerful. The idea of capturing a value and setting it originated with Boost PO. -* [The Lean Mean C++ Option Parser]: One header file is great, but the syntax is atrocious, in my opinion. It was quite impractical to wrap the syntax or to use in a complex project. It seems to handle standard parsing quite well. -* [TCLAP]: The not-quite-standard command line parsing causes common shortcuts to fail. It also seems to be poorly supported, with only minimal bugfixes accepted. Header only, but in quite a few files. Has not managed to get enough support to move to GitHub yet. No subcommands. Produces wrapped values. -* [Cxxopts]: C++11, single file, and nice CMake support, but requires regex, therefore GCC 4.8 (CentOS 7 default) does not work. Syntax closely based on Boost PO, so not ideal but familiar. -* [DocOpt]: Completely different approach to program options in C++11, you write the docs and the interface is generated. Too fragile and specialized. -* [GFlags]: The Google Commandline Flags library. Uses macros heavily, and is limited in scope, missing things like subcommands. It provides a simple syntax and supports config files/env vars. -* [GetOpt]: Very limited C solution with long, convoluted syntax. Does not support much of anything, like help generation. Always available on UNIX, though (but in different flavors). -* [ProgramOptions.hxx]: Intresting library, less powerful and no subcommands. +| Library | My biased opinion | +|---------|-------------------| +| [Boost Program Options] | A great library if you already depend on Boost, but its pre-C++11 syntax is really odd and setting up the correct call in the main function is poorly documented (and is nearly a page of code).
