Custom Placeholders are designed for cases when the source texts contain some less common placeholders that are not highlighted in the source strings (in the Editor) by default.
Custom Placeholders could be configured in the Organization Settings > Custom placeholders page.
To configure your custom placeholder expression, you can use the elements from the expression syntax table. For example, if you’d like to highlight this
[[Placeholder1]], your expression might look like this:
start, then "[[", range "a,z,A,Z,0,9", limit "1,20", then "]]", end
To simplify things a bit, let’s deconstruct the expression above.
start – indicates the beginning of the expression.
then "[[" – means that your custom placeholder starts with two opening square brackets.
range "a,z,A,Z,0,9" – means that your custom placeholder might include characters ranging a-z and/or A-Z and/or 0-9.
limit "1,20" – means that the length of the placeholder is from 1 to 20 characters.
then "]]" – means that your custom placeholder ends with two closing square brackets.
end – indicates the end of the expression.
As soon as the custom placeholders are assigned to the project, project members will see them highlighted in the Editor during the translation process.
