Simplify Localization with Design Pattern Automation
an AOP success story by Yan Cui@theburningmonk
Hi, my name is Yan Cui@theburningmonk
plz ask question in the questions window
more text than first 3 Harry Porter books COMBINED!
localization needs to be applied in many, many places!
traditionally…
ingest gettext (.po) file
msgid = original text msgstr = localized text
ingest gettext (.po) file
substitute display text
button.text = getLocalizedText("back");
label.text = getLocalizedText("baits");
monster.name = getLocalizedText(monster.name);
...
ingest gettext (.po) file
substitute display text
render translated text instead
but wait…
but wait…what if we add another type of domain object or add/change
an screen?
ingest gettext (.po) file
substitute display text
render translated text instead
ingest gettext (.po) file
substitute display text
render translated text instead
hard to get good test coverage scope is too big
easy for regressions to creep in during frequent release cycles
6 sins of traditional approach to localization
large up-front development effortnot future proof
duplicated effort for each client platformhard to get good test coverage
prone to regressionspressure on QA resources

what if we localize here?

so what goes here is already localized (where
necessary)

server team
1. ingest gettext (.po) file
2. check domain objects for string fields/properties
3. use localized text when transforming to DTO
4. repeat for next language

hey Watson! I found a Pattern!
“thou shall not burn me” - a server dev
to ingest .po files in .Net
to automate implementation patterns in .Net
ps. we had a convention of suffix DTO types with VO
