How to print the contents of all revisions of a particular file in Mercurial?

Question

Let's say I have 5 revisions of a README file. How do I view them all in Mercurial?

It would be nice to be able to limit the output, similar to:

hg log -l 10

I'm using PowerShell, so combined solutions are also welcome.

Answer 1

I don't know Powershell syntax, but you're looking for the hg cat command. Combined with the answer to your other question I would do it like this in a Unix shell (zsh in my case):

for r in $(hg log --template '{rev} ' README); do hg cat -r $r README; done

I first get all the revisions in which README was changed. They will be put into a big string like this:

% hg log --template '{rev} ' README
822 804 688 681 629 539 538

You then iterate over these revision numbers and call hg cat on each.
