Subject [jira] [Commented] (COR-26) Recommend standard getopt_longs for the utilities
Date Mon, 19 Jan 2015 02:00:37 GMT

    [ https://issues.apache.org/jira/browse/COR-26?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14282086#comment-14282086

Dennis E. Hamilton commented on COR-26:
---------------------------------------

The link is to the last post in the thread.

I think it is clear that the Commons CLI is a Java library, http://commons.apache.org/proper/commons-cli/

The APR apr_getopt functions are in C and described at the link http://apr.apache.org/docs/apr/1.5/group__apr__getopt.html
and the build instructions include CMake.  It is not clear what they do about using current
VC compilers, etc.

Much experimentation is needed to see what the desired approach should be.  It will help to
have an idea of what command-lines we want getopt for, as well.

> It is recommended that the command-line utilities provided by Corinthia use a common
getopt model with single-letter options, verbose word options and common shared options (--version,
--help, etc.).  stdin, stdout, and stderr should be redirectable (via the shell) and the utilities
should work with pipes (with appropriate encoding caveats).
> The same flavors can be used for all platforms, with filenames given in platform-specific
form (and "..." where needed) but parameters and options the same across platforms.
> The GNU getopt_long approach is widely-used.  http://en.wikipedia.org/wiki/Getopt
