Undo "discard" local changes after merge in TortoiseHg - mercurial

I just lost a bunch of work because I accidentally clicked "discard" when I tried to merge in remote changes.
Can anyone recommend a way to recover my uncommitted local changes? :'(
Does Mercurial or TortoiseHg store a backup somewhere of the last deleted changes?

Was it through this window?
In which case, I'm afraid, no, there is not.
I believe this window calls the command hg update -r MY_BRANCH -C, where the -C flag denotes there will be no backups.
As an aside, if it was a different way, you'd want to be looking for .orig files, which would be the format of the backup.

Is there a way to tell mercurial 'delete all files that are deleted in local' during a merge?

I've been assigned the task to do a huge merge, ~1500 commits, on a mercurial project.
In the local fork we have deleted about ~200 files, right now I need to press d and enter for each file:
remote changed file/that/is/deleted/in/local which local deleted
use (c)hanged version or leave (d)eleted?
Is there a way to tell mercurial to choose to delete all those files?
Are you on a Unix-like system? If so, this command will automate answering "d" to all questions. That's what it's for. (Will only work if there are no other issues requesting manual intervention, of course.)
yes d | hg merge ...
If you're not, you could implement it yourself :-) E.g.,
perl -e "for (;1;) { print \"d\n\"; }" | hg merge ...
Or write a Windows batch file with an infinite loop (etc.)
YES.BAT | hg merge ...
since you are on windows, try using tortoise
https://tortoisehg.bitbucket.io/
add your project. then your working directory, you will be able to see the files affected, you can then
You deleted them on local? You can't just do an hg addremove? If they changed after removal, but before pushing I think you are out of luck :(
As per the second answer and its comments in Resolving conflicts: how to accept "their" changes automatically?,
hg merge --tool internal:local
will work.

How to reinstate most recent commit in Mercurial?

I've searched the docs of Mercurial and still am confused. What I'm wanting to do is just reinstate the last commit I made i.e. I want my project to go back to being exactly the same as it was when I made the last commit. I see hg revert, rollback, etc. and still am not understanding which is correct for this situation. Which should I use?
The hg rollback command is used to undo the last action that modified Mercurial's internal store, usually a pull or commit. So, if you want to undo your last commit hg rollback will work.
But it sounds like you want to undo all your uncommitted changes. You have two options. The hg revert --all command will undo all uncommitted changes. Each changed file is saved/backed-up with a .orig extension before being reverted.
If you don't need to preserve your changes in .orig files, run hg update -C. This clears out all uncomitted changes, without preserving anything.
If you have commited changesets and wish to remove them, I like the strip extension, strip extension. With it, you can remove explicit changesets from your history.
However, strip is an unforgiving command, i.e. if you get it wrong there is no retrieval unless you have a backup of the repo. You might prefer the prune command which comes with the evolve extension. Using prune, you can mark changesets as obsolete and they will no longer normally be visible in logs or tortoise. [You can make them visible by adding --hidden on an hg log command line, or in tortoise by enabling the Filter toolbar (from the view menu) and selecting 'Show/Hide hidden changesets'.]

How to undo all added files in Mercurial

Say I type hg add in Mercurial, and there a bunch of untracked files in my working directory that are not ignored. What is the easiest way to un-add all those files without explicitly typing the name of each file?
Can I just un-add them all with one command?
Preface
You must always ask questions, which contain as much information as possible. Because now your question, depending from some conditions, may have totally different answers.
Case One - no local modifications in already versioned files, only added (and not committed) files
hg revert will return your working directory to the state after the last commit, undoing all changes it it.
Case One - local edits, which you want to save and occasionally added files
Read about filesets in Mercurial.
Use fileset in the hg forget command, something like hg forget "set:added()".
Use hg revert or hg forget on the files (both do the same for a file you ran hg add on). To avoid typing out the filenames, you can use a fileset like this:
$ hg revert "set:added()"
This will revert the file back to how it looked in the working copy parent revision, i.e., it will become unknown again.
hg revert -r .^ path-to-file will revert the commit from the commit-set.
then commit and submit (if using jelly fish) and you'll see the files removed from the changeset. I don't know why .^ works yet, but somebody will probably know.
You could always just re-clone your repository and then replace (delete existing and then copy new) the .hg directory in your working folder with the one from the fresh clone... (assuming you have no pending commits..)

mercurial: recover from deleted repository after commit, before push

I have a mercurial repository my_project, hosted at bitbucket. Today I made a number of changes and commited them to my local repository, but didn't push them out yet.
I then majorly stuffed up and fatfingered rm -rf my_project (!!!!!).
Is there some way I can retrieve the changes that I committed today, given that I hadn't pushed them out yet? I know a day's worth of commits doesn't sound like much, but it was!
All the other clones I have of this project are only up-to-date to the most recent push (which didn't include today's changes).
cheers.
mercurial cannot save you. The data from mercurial is stored in a hidden directory in the base of your project folder. In your case, probably at my_project/.hg. Your recursive delete would have trashed this folder as well.
So maybe a file recovery tool?
No. The changes are only stored in the local repository directory (the .hg directory therein) until you've pushed. They're never put anywhere else (not even /tmp).
There is a possibility that you'll be able to recover the deleted files from the disk, though; search around for instructions and tools for doing that.
I'm afraid the commit is deleted together with the working copy and file recovery tools are your only option to recover the missing .hg folder. I see you could recover the code from the install — great!
If you're afraid of this happening again, then you could install a crude hook like
[hooks]
post-commit = R=~/backup-repos/$(basename "$PWD");
(hg init "$R"; hg push -f "$R") > /dev/null 2>&1 || true
That will forcibly push a copy of all your commits to a suitable repo under ~/backup-repos. The -f flag ensures that you will push a backup even if you play with extensions like rebase or mq that modify history. It will also allow pushing changesets from unrelated repos into the same backup repo — imagine two different repos named foo. So the backup repositories will end up with a gigantic pile of changesets after a while and you might want to delete them once in a while.
I tested this briefly and for everyday work I don't think you'll notice the overhead of the extra copy and you might thank yourself later :-)

Mercurial bulk delete

I've just recently moved a lot of my Views and Controllers into more appropriate locations and am now wanting to pull down recent changes from our central repo.
I've done a hg pull which worked fine and asked me to do a hg update to bring the changes down locally. This in turn informed me that I needed to do a hg merge however when I try this, I get a message stating that
abort: outstanding uncommitted changes
When I check this using hg status I see in the list all of the files that I've moved (so they're now deleted from their old location).
How do I tell Mercurial that I've removed these files? Do I have to go through each one of them and manually do a remove? Is this something that's possible using only the command line rather than doing it with a GUI tool?
From the command line to automatically hg rm the files you've removed you'd:
hg addremove
It's likely your GUI (you didn't say which you use) exposes that functionality too.
However, that's not what's causing your message. You have some already made local changes that mercurial does know about (unlike the removed files which it doesn't know about until you tell it), and you need a hg commit before you can merge.
