.TH Text.translate 3 2025-11-29 "Tomo man-pages"
.SH NAME
Text.translate \- perform multiple replacements
.SH LIBRARY
Tomo Standard Library
.SH SYNOPSIS
.nf
.BI Text.translate\ :\ func(text:\ Text,\ translations:\ {Text:Text}\ ->\ Text)
.fi
.SH DESCRIPTION
Takes a table mapping target texts to their replacements and performs all the replacements in the table on the whole text. At each position, the first matching replacement is applied and the matching moves on to *after* the replacement text, so replacement text is not recursively modified. See Text.replace() for more information about replacement behavior.
