Is there a way to push all bookmarks to another repo, all at once? (Mercurial)

Question

I am importing one Mercurial repo into another, maintaining history. There are several bookmarked heads on the default branch, and I want those bookmarked heads to still be bookmarked in the new, merged repo. As far as I can tell, the two ways to do this is to either,

1. pull each bookmark individually
2. pull the entire thing and recreate the bookmarks by hand.

Answer 1

Extending the previous answer, here's how to push all branches using awk and the output of hg bookmarks in bash:

hg bookmarks | awk '{if (NF == 3) print $2; else print $1;}' | xargs -n 1 hg push -f -B

Answer 2

Unix:

hg push $(hg bookmarks -T "-B {bookmark} ")

Windows:

for /f "delims=" %A in ('hg bookmarks -T "-B {bookmark} "') do @hg push %A

PowerShell:

hg bookmarks -T "{bookmark}\n" | %{ Write-Host === Bookmark $_ === ; hg push -B $_ }
