I'm developing a [webapp](https://cxmanager.live) with Nim as the backend. I
need to support multiple languages with an easy and quick way to add further
language support. Besides supporting multiple languages, I also need the return
to be based on the host.
I have found a way which works quite well, but I don't think it's an optimal
way, if my languagefile scales too much. So I'm looking for performance
suggestions or another approach, if this isn't the perfect solution.
**languagefile.cfg**
title_ENh = Hubanize
title_DKh = Hubanize
title_ENc = Cx Manager
title_DKc = Cx Manager
help_ENh = Help
help_DKh = Hjælp
help_ENc = Help
help_DKc = Hjælp
**languageparser.nim**
proc langInit(cfgFilename: string): Table[string, string] =
## Parse the languagefile
let inputString = readFile(cfgFilename)
result = initTable[string, string]()
for line in inputString.splitLines:
result[chunks[0]] = chunks[1]
let langGet* = langInit("languagefile.cfg")
proc langGen*(identifier, pageID: string, lang = "EN"): string =
## Retrive language item
## identifier => The item to retrieve
## pageID => c or h based on the host address. Accessed per user with
c.pageID
## lang => Language. Accessed per user with c.lang - test users can have
empty lang, therefor standard "EN"
try:
return langGet[identifier & "_" & lang & pageID]
except:
return ""
echo langGen("title", "c", "EN") # = Cx Manager
echo langGen("help", "h", "DK") # = Hjælp
