Package Exports

stringf

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (stringf) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Pseudocode for implement in your own language

input:
    a string, s
    a map string to string, paramMap
output:
  a string with param replaced

let ESCCHAR ← '#', i ← 0, output ← ""

while i < length(s) do
    if s[i] = ESCCHAR then
        let j ← i + 1
        while j <= length(s) and s[j] = ESCCHAR do
            j ← j + 1
            if (j - i) mod 2 = 0 then
                output ← output + ESCCHAR
        if (j - i) mod 2 = 0 then
            output ← output + s[j]
        else
            let param ← ""
            while j < length(s) and s[j] ≠ ' ' do
                param ← param + s[j]
                j ← j + 1
            if length(param) > 0 then
                output ← output + paramMap[param]
            if j = length(s) then
                return output
            if s[j] = ' ' then
                output ← output + ' '
        i ← j + 1
    else
        output ← output + s[i]
        i ← i + 1
return output
