HG(1) ===== Matt Mackall NAME ---- hg - Mercurial source code management system SYNOPSIS -------- 'hg' [-v -d -q -y] [command options] [files] DESCRIPTION ----------- The hg(1) command provides a command line interface to the Mercurial system. OPTIONS ------- --debug, -d:: enable debugging output --quiet, -q:: suppress output --verbose, -v:: enable additional output --noninteractive, -y:: do not prompt, assume 'yes' for any required answers COMMAND ELEMENTS ---------------- files ...:: indicates one or more filename or relative path filenames path:: indicates a path on the local machine revision:: indicates a changeset which can be specified as a changeset revision number, a tag, or a unique substring of the changeset hash value repository path:: either the pathname of a local repository or the URI of a remote repository. There are two available URI protocols, http:// which is fast and the old-http:// protocol which is much slower but does not require a special server on the web host. COMMANDS -------- add [files ...]:: Schedule files to be version controlled and added to the repository. The files will be added to the repository at the next commit. addremove:: Add all new files and remove all missing files from the repository. New files are ignored if they match any of the patterns in .hgignore. As with add, these changes take effect at the next commit. annotate [-r -u -n -c] [files ...]:: List changes in files, showing the revision id responsible for each line This command is useful to discover who did a change or when a change took place. options: -r, --revision annotate the specified revision -u, --user list the author -c, --changeset list the changeset -n, --number list the revision number (default) cat [revision]:: Output to stdout the given revision for the specified file. If no revision is given then the tip is used. clone [-U] [dest]:: Create a copy of an existing repository in a new directory. If the destination directory is specified but doesn't exist, it is created. If no destination directory is specified, it defaults to the current directory. The source is added to the new repository's .hg/hgrc file to be used in future pulls. For efficiency, hardlinks are used for cloning whenever the source and destination are on the same filesystem. options: -U, --no-update do not update the new working directory commit [-A -t -l -t -u -d ] [files...]:: Commit changes to the given files into the repository. If a list of files is omitted, all changes reported by "hg status" will be commited. The HGEDITOR or EDITOR environment variables are used to start an editor to add a commit comment. Options: -A, --addremove run addremove during commit -t, --text use as commit message -l, --logfile show the commit message for the given file -d, --date record datecode as commit date -u, --user record user as commiter aliases: ci copy :: Mark file as a copy or rename of a one This command takes effect for the next commit. diff [-r revision] [-r revision] [files ...]:: Show differences between revisions for the specified files. Differences between files are shown using the unified diff format. When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent. export [revision]:: Print the changeset header and diffs for a particular revision. The information shown in the changeset header is: author, changeset hash, parent and commit comment. forget [files]:: Undo an 'hg add' scheduled for the next commit. heads:: Show all repository head changesets. Repository "heads" are changesets that don't have children changesets. They are where development generally takes place and are the usual targets for update and merge operations. history:: Print a log of the revision history of the repository. By default this command outputs: changeset id and hash, tags, parents, user, date and time, and a summary for each commit. The -v switch adds some more detail, such as changed files, manifest hashes or message signatures. To display the history of a given file, see the log command. identify:: Print a short summary of the current state of the repo. This summary identifies the repository state using one or two parent hash identifiers, followed by a "+" if there are uncommitted changes in the working directory, followed by a list of tags for this revision. aliases: id import [-p -b -q] :: Import a list of patches and commit them individually. options: -p, --strip directory strip option for patch. This has the same meaning as the correnponding patch option -b base directory to read patches from aliases: patch init:: Initialize a new repository in the current directory. log :: Print the revision history of the specified file. To display the revision history for the whole repository, use the history command. manifest [revision]:: Print a list of version controlled files for the given revision. The manifest is the list of files being version controlled. If no revision is given then the tip is used. parents:: Print the working directory's parent revisions. pull :: Pull changes from a remote repository to a local one. This finds all changes from the repository at the specified path or URL and adds them to the local repository. By default, this does not update the copy of the project in the working directory. options: -u, --update update the working directory to tip after pull push :: Push changes from the local repository to the given destination. This is the symmetrical operation for pull. It helps to move changes from the current repository to a different one. If the destination is local this is identical to a pull in that directory from the current one. The other currently available push method is SSH. This requires an accessible shell account on the destination machine and a copy of hg in the remote path. Destinations are specified in the following form: ssh://[user@]host[:port]/path rawcommit [-p -d -u -F -t -l]:: Lowlevel commit, for use in helper scripts. This command is not intended to be used by normal users, as it is primarily useful for importing from other SCMs. recover:: Recover from an interrupted commit or pull. This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it. remove [files ...]:: Schedule the indicated files for removal from the repository. This command shedules the files to be removed at the next commit. This only removes files from the current branch, not from the entire project history. aliases: rm root:: Print the root directory of the current repository. serve [-a addr -n name -p port -t templatedir]:: Start a local HTTP repository browser and pull server. options: -a, --address address to use -p, --port port to use (default: 8000) -n, --name name to show in web pages (default: working dir) -t, --templatedir web templates to use status:: Show changed files in the working directory. The codes used to show the status of files are: C = changed A = added R = removed ? = not tracked tag [-t -d -u ] [revision]:: Name a particular revision using . Tags are used to name particular revisions of the repository and are very useful to compare different revision, to go back to significant earlier versions or to mark branch points as releases, etc. If no revision is given, the tip is used. To facilitate version control, distribution, and merging of tags, they are stored as a file named ".hgtags" which is managed similarly to other project files and can be hand-edited if necessary. options: -t, --text message for tag commit log entry -d, --date datecode for commit -u, --user user for commit Note: Mercurial also has support for "local tags" that are not version-controlled or distributed which are stored in the .hg/hgrc file. tags:: List the repository tags. This lists both regular and local tags. tip:: Show the tip revision. undo:: Undo the last commit or pull transaction. update [-m -C] [revision]:: Update the working directory to the specified revision. By default, update will refuse to run if doing so would require merging or discarding local changes. With the -m option, a merge will be performed. With the -C option, local changes will be lost. options: -m, --merge allow merging of branches -C, --clean overwrite locally modified files aliases: up checkout co verify:: Verify the integrity of the current repository. This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks and indices. ENVIRONMENT VARIABLES --------------------- HGEDITOR:: This is the name of the editor to use when committing. Defaults to the value of EDITOR. HGMERGE:: An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file, ancestor file. The default program is "hgmerge", which is a shell script provided by Mercurial with some sensible defaults. HGUSER:: This is the string used for the author of a commit. EMAIL:: If HGUSER is not set, this will be used as the author for a commit. LOGNAME:: If neither HGUSER nor EMAIL is set, LOGNAME will be used (with '@hostname' appended) as the author value for a commit. EDITOR:: This is the name of the editor used in the hgmerge script. It will be used for commit messages if HGEDITOR isn't set. Defaults to 'vi'. PYTHONPATH:: This is used by Python to find imported modules and may need to be set appropriately if Mercurial is not installed system-wide. FILES ----- .hgignore:: This file contains regular expressions (one per line) that describe file names that should be ignored by hg. .hgtags:: This file contains changeset hash values and text tag names (one of each seperated by spaces) that correspond to tagged versions of the repository contents. $HOME/.hgrc, .hg/hgrc:: This file contains defaults and configuration. Values in .hg/hgrc override those in .hgrc. NAMED REPOSITORIES ------------------ To give symbolic names to a repository, create a section in .hgrc or .hg/hgrc containing assignments of names to paths. Example: ----------------- [paths] hg = http://selenic.com/hg tah = http://hg.intevation.org/mercurial-tah/ ----------------- LOCAL TAGS ---------- To create tags that are local to the repository and not distributed or version-controlled, create an hgrc section like the following: ---------------- [tags] working = 2dcced388cab3677a8f543c3c47a0ad34ac9d435 tested = 12e0fdbc57a0be78f0e817fd1d170a3615cd35da ---------------- HOOKS ----- Mercurial supports a set of 'hook', commands that get automatically executed by various actions such as starting or finishing a commit. To specify a hook, simply create an hgrc section like the following: ----------------- [hooks] precommit = echo "this hook gets executed immediately before a commit" commit = hg export $NODE | mail -s "new commit $NODE" commit-list ----------------- NON_TRANSPARENT PROXY SUPPORT ----------------------------- To access a Mercurial repository through a proxy, create a file $HOME/.hgrc in the following format: -------------- [http_proxy] host=myproxy:8080 user= passwd= no=,,,... -------------- "user" and "passwd" fields are used for authenticating proxies, "no" is a comma-separated list of local host names to not proxy.
