in reply to

Also observed that columns in nim doc (on *.nim files) are shifted by 3.

(i prefer code comments to maintain threading)
take a look at https://gist.github.com/timotheecour/e53f06241914fa1e20a40f631edfae10

run nim doc -d:case1 main (and -d:case2, -d:case3)

before this PR, line and column number is bad
after this PR, line and column number is also bad (maybe a bit worse?)

IMO we should report line and column numbers wrt source file, and not offset it by "## ".len; unless I'm missing something it should be both simpler and more robust.

But I suggest merging this PR to make progress and addressing this inconsistent line/col numbering in followup PR.

the case1 is just incorrectly adjusted line in parseHeadline. We can fix it with an appropriate test now.

The multiline case2 and case3 are more difficult, some investigation will be needed.

in future PR we can add an outplace version of toLocation to make life simpler in here and elsewhere, useful wherever performance is not critical (like here). Or you could also use sugar.dup

instead of specifying line, col in all callers (and doing so incorrectly, see below with (1,1) instead of (LineRstInit,ColRstInit) which is (1,0), how about add an overload of rstParse:

proc rstParse*(text, filename: string, hasToc: var bool, options: RstParseOptions, findFile: FindFileHandler = nil, msgHandler: MsgHandler = nil): PRstNode =
  rstParse(line=LineRstInit,column=ColRstInit,...)

will simplify and make these correct:

compiler/docgen.nim:161:12:  result = rstParse(text, filename, line, column, hasToc, rstOptions,
lib/packages/docutils/rst.nim:2593:6:proc rstParse*(text, filename: string,
lib/packages/docutils/rstgen.nim:1509:13:  var rst = rstParse(s, filen, line=LineRstInit, column=ColRstInit,

tests/stdlib/trstgen.nim:425:30:    rstGenera.renderRstToOut(rstParse(input10, "", 1, 1, option, {}), output10)
tests/stdlib/trstgen.nim:451:32:    rstGenera11.renderRstToOut(rstParse(input11, "", 1, 1, option11, {}), output11)
tests/stdlib/trstgen.nim:480:32:    rstGenera12.renderRstToOut(rstParse(input12, "", 1, 1, option12, {roSupportMarkdown}), output12)
tests/stdlib/trstgen.nim:577:30:    rstGenera.renderRstToOut(rstParse(input1, "", 1, 1, option, {}), output1)

can be done in cleanup PR though

ok, will be overloaded in the future.
