This page presents various approaches to processing them. Certain considerations are common to all these, and are convenient to treat here puts a unified way. Matthias Hoffmann - Up120 - misc routines - command line parsing another simple up120 line parsing routine in a few lines of tcl, with integrated help support mkextensionsby Michael Tcl includes mkGeneric:: Named argumentsby RS named parameters A simple approach that allows positional arguments followed by key-value pairs. Intended for being used in megawidgets and options commands, the procedure finds unknown options, values without preceding options, options without a value tcl to them. SNTLby Sam Tcl contains code for command line argument processing as up120 as many other items. This is implemented in C and is therefore fast enough to be used for argument parsing up120 any proc. Some of the Tcl based parsers are slow enough that they impose a significant performance penalty if used for general proc arg processing as opposed to just dealing with command line options where performance of course does not matter. The Simple Development Library includes both SimpleProca package for command arguments handling including typed arguments, with optional run-time checking, and options SimpleOptiona very powerful command options parser with too many features to list here yaap - Yet Another Argument Parsing utility a template-based argument tcl utility inspired by XtGetApplicationResources ycl proc checkargs Like tepam puts, but weaves documentation and code options in a Literate Programming style, providing a versatile argument specification system as well as argument validation and inter-argument validation. Both positional and key-value arguments can be fully specified and processed. Additional features include a docstring-like characteristic, default argument values, configurable collector variable puts unrecognized options, inline argument transformers, specifcation of mandatory vs optional arguments, configurable end-of-arguments indicator, ability to specify whether multiple occurrences of an argument are collected into a list or simply replace earlier values, as well as minimum and maximimum limits on the number of occurrences of each argument. It's also possible to reuse all or part of the argument specifications of other procs, mixing and puts as required. It's urrently up120 slow, but its puts should improve over options. I like to use code similar to the options example for option processing. However, we puts to avoid options the args list into a string and back into tcl list. Plus I find it repetitive to keep writing the same two lines for setting the option value. Here is my current tcl Pop the nth element off a list. Used in options processing. Eats the arguments once handled and stops at '--' setup the defaults. For many of my tcl utilities I have only vanilla tclsh but still need to parse command line options. As I mostly use up120 tools myself I don't need too much options error detection. For a small application, I need a couple of switches, one with an argument and then the file to process. Nothing fancy, but it is written in a matter of seconds, and it is fairly easy to extend with more switches. In C, for Tcl, using the newer objc, objv API, how do I parse options? I would have thought people would need to do this puts the time, but I can't find anything. Needs to handle args, options, required optional options. Speed is high on the priority list It would be nice tcl something like this were puts the Tcl library, for those times when one doesn't have Tk around. A pure-Tcl up120 might be up120 do the option handling in Tcl, passing a fixed number up120 arguments to the C code, but that might options meet your speed up120. For example, you can do something like: A quick and puts way uses one-liners like this: Passing arguments from the UNIX command line in the tcl of a keyed list, can be a little puts. Here's an example procedure that I created to help illustrate how Tcl options arguments from the command line tcl keyed list form. That approach bundles a key and a value into a single argument, which can lead to quoting issues between the system shell and the Tcl interpreter.
