# Tcl Benchmark File
#
# This file contains a number of benchmarks for the 'wcswidth' package.
# This allow developers to monitor/gauge/track package performance.
#
# (c) 2022 Andreas Kupries <andreas.kupries@gmail.com>
# We need at least version 8.5 for the package and thus the benchmarks.

## Setting up the environment ...
package forget textutil::wcswidth
catch {namespace delete ::textutil::wcswidth}
source [file join [file dirname [info script]] wcswidth.tcl]

## Benchmarks. Fixed, semi-random selection of codepoints across the range.
## A better way may be to scan the entire range of codepoints and then chart the performance.
## With the small set used here it looks as if there is some dependency on the codepoint, with
## higher points taking longer.
#
## I had actually expected that the very low codepoints would do worse as they have to go through
## the entire linear chain of if-commands until the `return 1`, i.e. the main fallback, is reached.
foreach codepoint {
0 64 127 128 1000 10000 20000 100000 200000 262141 1114111
