# Declare template folder
templateFolder("templates")
proc render(title: string): string =
## Renders template and returns HTML string
##
## `title` is template argument
renderTemplate("index.html")
# Below is code I am trying to do, but don't know how...
const file_list = @["index.html", "index2.html", "index3.html"]
const target_dir = "public"
# a function call to render all files to target dir at compile time
renderFiles(file_list, target_dir)
I have tried many way, including using templates, but failed. please help |

OK, what about this case? const file_list = @["page_1.html", "page_2.html", "page_3.html"]
const target_dir = "public"
# a function call to render all files to target dir at compile time
renderFiles(file_list, target_dir)

I found a solution using templates, I know it's not optimal solution, but post it in case someone need it, btw it's good to learn how nim compile time computation works const listFiles = @["page_1.html", "page_2.html", "page_3.html"]
template renderMyTemplate(fileName) =
case listFiles.find(fileName) :
of 0:
renderTemplate(listFiles[0])
of 1:
renderTemplate(listFiles[1])
of 2:
renderTemplate(listFiles[2])
else:
echo "file not found"
proc render(fileName: string, element: string, class: string): string =
renderMyTemplate(fileName)
how to use for f in listFiles:
let e = "elementName"
let c = "className"
writeFile(target_dir, render(f,e,c))please note if you add new file to listFiles, you need to manually add |

if someone can offer a solution which use macro, will be greatly appreciated, I can also learning something from you, thx! |

You can use this example to fetch files from your templates directory: import
os,
macros,
happyx
macro getFilesInDir*(directory: static[string]): untyped =
# result is [file1, file2, file3, etc.]
result = newNimNode(nnkBracket)
for i in directory.walkDirRec(followFilter = {}, relative = true):
result.add(newLit(i))
const files = getFilesInDir("templates")
echo filesAnd example below shows how you can replace macro renderTemplates*(arr: static[openarray[string]]): untyped =
result = newNimNode(nnkCaseStmt).add(
newCall("find", ident"files", ident"filename")
)
for i in arr.low..arr.high:
result.add(newNimNode(nnkOfBranch).add(
newLit(i),
newCall("renderTemplate", newLit(arr[i]))
))
template renderMyTemplate(filename: string) =
renderTemplates(arr)
proc render(fileName: string, element: string, class: string): string =
renderMyTemplate(filename)
serve "127.0.0.1", 5000:
get "/":
for f in files:
let e = "elementName"
let c = "className"
writeFile(target_dir, render(f,e,c))

it works!! code below proc handleNoMatch() =
echo "file not found"
macro renderTemplates*(arr: static[openarray[string]]): untyped =
result = newNimNode(nnkCaseStmt).add(
newCall("find", ident"litfiles", ident"fileName")
)
for i in arr.low..arr.high:
result.add(newNimNode(nnkOfBranch).add(
newLit(i),
newCall("renderTemplate", newLit(arr[i]))
))
# Handling the case where 'find' does not match any index
result.add(newNimNode(nnkElse).add(
newCall("handleNoMatch") # Replace with appropriate action
))but there are some errors |

You can use this example to fetch files from your templates directory:
And example below shows how you can replace
case statementto macro but keep logic in runtime still:
