gknowles / dimcli Goto Github PK

Hello,
it's not clear from the project description what compilers are supported or which C++ standard it conforms to. I mean compilers other than VS 2015.
I just tried GCC 6 and it shows a long list of errors, the first one being:

cli.cpp:57:11: error: underlying type mismatch in enum ‘enum Dim::Cli::NameListType’
 enum Cli::NameListType {
           ^~~~~~~~~~~~
In file included from cli.cpp:7:0:
../include/dimcli/cli.h:155:25: error: previous definition here
     enum NameListType : int;
                         ^~~

Git style subcommands and distributed argument declaration

Speaking as a mainly Windows programmer I don't really care very much, but yeah...

When someone passes in a random switch there should be a way to see it, instead of always being an error (or ignored).

My first ever use of it (it is rather painful) and the committee deprecated it a few months later.

Description:
Dimcli 5.0.0 build failed with Visual Studio 2019 due to warning C5055.

Failures:
5>F:\0814\vcpkg\buildtrees\dimcli\src\v5.0.0-89211a3afb\libs\dimcli\cli.h(1501,15): error C2220: warning treated as error - no 'object' file generated [F:\0814\vcpkg\buildtrees\dimcli\x64-windows-dbg\cli.vcxproj]

Attach my build log:

hello,

the vcpkg package is still for version 5.0.2 and is not updated to the latest version

For example, "help" could be matched by --hel, --he, and --h, as well as --help

Ambiguous matches would fail with something like:
Ambiguous option "--h", possibilities: --help, --http

More control over how help is formatted, both overall styles and substituting variable and value names

There could be callback events for parsing, validation, help generation, etc

Allow tuple<> arguments that would match contiguous values. For example tuple<int,int> could match "-t 1 2"

Expand the command line by replacing "@" arguments with the contents of

Moving the file to the binary dir helps.

For example integer could accept locale, scientific, engineering (K, Ki, M, Mi, etc), formats. That way any of the following could be used to give you "10,000":
10000
10,000
1e+4
10k

This could apply to anything that has multiple representations, such as timepoints, durations, host names, etc.

Could you please point out what this library offers or how it varies from CLI11 ? https://github.com/CLIUtils/CLI11

The docs say:

Git style subcommands are created by either cli.command("cmd"), which changes the cli objects context to the command, or with opt.command("cmd"), which changes the command that option is for.

However when I try that:

static auto & command = Dim::Cli().command("apple").desc("Change color of the apple.");
static auto & color = command.opt<string>("color", "red");

I get a segfault:
