These are notes for using Mercurial. (They really don’t belong in the Java QRG section, but since I use Mercurial to get Java source files, it feels appropriate for me to include them here.)
|init||initializes a repository as a mercurial repository|
|status||gets the status of the repo|
|add –all||adds all the files|
|add sample.txt||adds a specific file to the repo|
|add *.md||add all files with an .md extension to the repo|
|add .||add all files of all extensions to the repo|
|commit -m “here’s my commit msg”||commit the current files to the repository|
|log||get a log of the commits|
|remote add origin https://github.com/your_repo||set the github repo destination to your repo|
|push -u origin master||push to your repo|
|pull origin master||get files from the repo|
|get diff HEAD||see the changes|
|rm ‘*.dita’||remove all the files with the .dita extension from the repository|
|merge||merge your local files with the latest working set|
|up||go to the working set (the latest changeset)|
|diff||see the differences between stuff|
|clone||clones a repository into a folder in the current directory. also sets up hg in this local repository. cd to /users/tjohnson/projects. Then
|up or update||updates the content to the latest working copy|
||this lets you know what the latest parent is. still not entirely sure what the parent means.|
||update to the latest working set|
||allows you to rollback to an earlier changeset|
||lets you know what heads you’re merging here.|
||makes it so an added file is no longer added.|
||opens a file so you can edit it (not HG specific)|
||opens a file in sublime so you can edit it.|
||shows ally he outgoing changes|
Basic flow in pushing content
- Make changes, and then go
hg commit -m "commit message"
- If there are problems in pushing the content, then you type
- If there are conflicts, type
- It will create a bunch of merges in the file. go through and sort it out first. remove all the »»» and «««<.
hg resolve --mark file.txt. this will mark the conflict as resolved.
- Save the file and type
hg commit -m "commit message".
hg push. Now there shouldn’t be any problems.
Basic flow in pulling content:
- Go to
hg pullto get the latest changeset.
hg updateto update to the latest working copy. (you can also do
hg pull -uto accomplish it all in one command.)
- If there are problems, you’re notified about them. do
- The files get merged and you have to go through and sort out the conflicts. remove all the »»» and «««<.
hg resolve --mark file.txtthis will mark the conflict as resolved.
hg commit -m "commit message"
If you’re asked if you want to put multiple heads in the same file, don’t do it. It messes things up.
- Everything is a changeset. when you commit it, that diff is a changeset.
- All that cloning does is take all the changesets and add them to your machine.
- changeset numbers are different per each box. the numbers are for your own info.
pullgrabs all the change sets.
- hg forget: after you delete a file, in order to tell Mercurial not to warn you that it’s missing, use the
Testing the multi-user scenario
Create a repository called remote:
hg mkdir remote cd remote hg init
Now clone the repository into 2 other repositories:
hg clone remote jp hg clone remote dm
Now open up several windows in iTerm: **Shell > Split Vertically **(do it twice)
In your other windows, cd to jp and cd to dm.
Now create a sample file and put it in remote. Make changes with one user and push. Pull from another user and make changes, etc. Works really well.
Clone a repository
cd to /users/tjohnson/projects hg clone <mercurial URL>
Add all files to a repository
hg add .
Commit the files
hg commit -m "your commit msg"
Get the logs
Push to the central repository
Create an HG repository
do this if you’re creating an HG repository locally:
Get the latest files
See list of changed files
See what changed in a specific file
hg diff file.txt
Update the working directory
Go forward or backwards in the directory
hg update -r 0
