This is a workaround for #3182, no forward declarations. You can now do
this:
```nim
async:
proc bar(): Future[T]
proc foo() = await bar()
proc bar() {.async.} = echo(123); await foo()
```
Saw in https://github.com/nim-lang/nimforum/issues/41 that there was an
issue in rendering inline images. Traced back through rstgen and found
that it was not counting something like:
`.. image:: http://i.imgur.com/oCem13Y.png` as valid since it contained
a period, and this wasn't in the set of valid characters, so the empty
string is returned by default.
Added a period to the allowable characters, and now renders correctly.
Test case:
```
import rst, rstgen, strtabs
var docConfig: StringTableRef
docConfig = rstgen.defaultConfig()
docConfig["doc.smiley_format"] = "/images/smilieys/$1.png"
proc rstToHtml(content: string): string =
result = rstgen.rstToHtml(content, {roSupportSmilies,roSupportMarkdown},
docConfig)
var a: string = rstToHtml(".. image:: http://i.imgur.com/oCem13Y.png")
echo a
```
type, then converter, then 3 iterators lowest- to highest-level
(also fastest to slowest) including a new intermediate iterator
lines(MemFile, buffer) that is more like readLine(File) in case
that helps anyone port code.
Add doc comments.
Also have toString just use newString+c_memcpy instead of
currently fragile toNimStr which Araq wants a separate PR for.
Ensure the correct destination hostname is used in the request, otherwise the request will fail in one of a number of interesting ways when using a proxy.
Fixes https://github.com/nim-lang/Nim/issues/3166
* Removed extraneous exports (and converted const array to separate consts)
* Renamed dayOfWeek, dayOfWeekJulian to getDayOfWeek and getDayOfWeekJulian
* Renamed decodeTime procs to timeToTimeInfo and timeToTimeInterval
* Added some basic descriptions to docs
