NAME
shtk - Application Programming Interface (API) of the Shell Toolkit
DESCRIPTION
The Shell Toolkit, or shtk for short, is a collection of modules written
in sh(1) that provide common functionality to simplify the implementation
of complex shell scripts. This page provides an introduction to writing
scripts using shtk and serves as a reference to all the provided modules
by it.
Script structure
Scripts using shtk follow this structure:
shtk_import module1
shtk_import moduleN
# possibly define globals here
some_custom_function() {
local arg1="${1}"; shift
local arg2="${1}"; shift
# do something
}
main() {
# program entry point; automatically invoked
}
In particular, note: that there is no shebang line at the beginning of
the script; that there is no explicit call to main; and that there is no
code outside of shell functions other than for calls to shtk_import(3).
Script compilation
The shtk(1) tool offers a compilation process for scripts using shtk(3).
In this context, compilation just refers to the addition of
initialization boilerplate code to the script so that the correct modules
can be located and that a well-known shell interpreter is used.
Modules
The shtk_import(3) function depicted above is used to bring the specified
modules into the script. For details on all existing modules, see the
list of cross-referenced pages in the SEE ALSO section below.
