execline is a (non-interactive) scripting language, like sh; but its
syntax is quite different from a traditional shell syntax. The
execlineb program is meant to be used as an interpreter for a text
file; the other commands are essentially useful inside an execlineb
script.
execline is as powerful as a shell: it features conditional loops,
getopt-style option handling, filename globbing, and more. Meanwhile,
its syntax is far more logic and predictable than the shell's syntax,
and has no security issues.
NOTE:
Upstream recommends building skarnet.org softwares with static libraries
as most of skarnet.org softwares are small enough that using shared
libraries are generally not worth using. Therefore, by default, shared
libraries are not built and binaries are linked against the static
versions of the skarnet.org libraries.
If you want to also build the shared libraries, pass BUILD_SHARED=yes
environment variable to the SlackBuild script like below:
BUILD_SHARED=yes ./execline.SlackBuild
Similarly, to avoid building the static libraries, you can pass
BUILD_STATIC=no to the script. For example, to only build the shared
libraries and not the static ones, you can do something like:
BUILD_SHARED=yes BUILD_STATIC=no ./execline.SlackBuild
If you just want to build and use skarnet.org softwares, building only
the static libraries should be sufficient.
If you want the binaries to be linked against the shared versions of the
skarnet.org libraries, pass LINK_SHARED=yes to the script.
