Usage

Run dotdrop --help to see all available options.

Basic usage

The basic use of dotdrop is

• import a file/directory to manage (this will copy the files from the filesystem to your dotpath): dotdrop import <somefile>
• install the dotfiles (will copy/link those from your dotpath to the filesystem): dotdrop install

Then if you happen to update the file/directory directly on the filesystem (add new file/dir, edit content, etc) you can use the update command to mirror back those changes in dotdrop.

For more advanced uses:

• dotdrop --help for the cli usage.

Profile

The default profile used by dotdrop is the hostname of the host you are running dotdrop on.

It can be changed:

• using the command line switch -p --profile=<profile>
• by defining it in the env variable DOTDROP_PROFILE

Import dotfiles

The import command imports dotfiles to be managed by dotdrop. It copies the dotfile to your dotpath and updates the config file with the new entry.

Note that dotdrop will dereference all symlinks when importing a file or directory.

For example to import ~/.xinitrc

$ dotdrop import ~/.xinitrc
	-> "/home/user/.xinitrc" imported

1 file(s) imported.

You can control how the dotfile key is generated in the config file with the config entry longkey (per default to false).

Two formats are available:

• short format (default): take the shortest unique path
• long format: take the full path

For example ~/.config/awesome/rc.lua gives

• f_rc.lua in the short format
• f_config_awesome_rc.lua in the long format

Importing ~/.mutt/colors and then ~/.vim/colors will result in

• d_colors and d_vim_colors in the short format
• d_mutt_colors and d_vim_colors in the long format

Dotfiles can be imported as a different file with the use of the command line switch --as (effectively selecting the src part of the dotfile in the config). It is however recommended to use templating to avoid duplicates and optimize dotfiles management.

$ dotdrop import ~/.zshrc --as=~/.zshrc.test

For more options, see the usage with dotdrop --help

Install dotfiles

The install command installs/deploys dotfiles managed by dotdrop from the dotpath to their destinations.

$ dotdrop install

The dotfile will be installed only if it differs from the version already present on its destination.

some available options

• -t --temp: install the dotfile(s) to a temporary directory for review (it helps to debug templating issues for example). Note that actions are not executed in that mode.
• -a --force-actions: force the execution of actions even if the dotfiles are not installed
• -f --force: do not ask any confirmation

To ignore specific pattern during installation see the ignore patterns

For more options, see the usage with dotdrop --help

Compare dotfiles

The compare command compares dotfiles on their destination with the one stored in your dotpath.

$ dotdrop compare

The diffing is done by the unix tool diff in the backend, one can provide its specific diff command using the config entry diff_command.

To ignore specific pattern, see the ignore patterns

It is also possible to install all dotfiles for a specific profile in a temporary directory in order to manually compare them with the local version by using install and the -t switch.

For more options, see the usage with dotdrop --help

List profiles

The profiles command lists defined profiles in the config file

$ dotdrop profiles

Dotdrop allows to choose which profile to use with the --profile switch if you use something else than the default (the hostname).

The default profile can also be changed by defining the DOTDROP_PROFILE environment variable.

List dotfiles

The files command lists the dotfiles declared for a specific profile.

$ dotdrop files --profile=some-profile
f_xinitrc
	-> dst: /home/user/.xinitrc
	-> src: /home/user/dotdrop/dotfiles/xinitrc
	-> link: nolink

By using the -T --template switch, only the dotfiles that are using templating are listed.

It is also possible to list all files related to each dotfile entries by invoking the detail command, for example:

$ dotdrop detail
dotfiles details for profile "some-profile":
f_xinitrc (dst: "/home/user/.xinitrc", link: nolink)
	-> /home/user/dotdrop/dotfiles/xinitrc (template:no)

This is especially useful when the dotfile entry is a directory and one wants to have information on the different files it contains (does a specific file uses templating, etc).

For more options, see the usage with dotdrop --help

Update dotfiles

The update commands will updates a dotfile managed by dotdrop by copying the dotfile from the filesystem to the dotpath. Only dotfiles that have differences with the stored version are updated. A confirmation is requested from the user before any overwrite/update unless the -f --force switch is used.

Either provide the path of the file containing the new version of the dotfile or provide the dotfile key to update (as found in the config file) along with the -k --key switch. When using the -k --key switch and no key is provided, all dotfiles for that profile are updated.

## update by path
$ dotdrop update ~/.vimrc

## update by key with the --key switch
$ dotdrop update --key f_vimrc

If not argument is provided, all dotfiles for the selected profile are updated.

To ignore specific pattern, see the dedicated page

There are two cases when updating a dotfile:

The dotfile doesn't use templating

The new version of the dotfile is copied to the dotpath directory and overwrites the old version. If git is used to version the dotfiles stored by dotdrop, the git command diff can be used to view the changes.

$ dotdrop update ~/.vimrc
$ git diff

The dotfile uses templating

The dotfile must be manually updated, three solutions can be used to identify the changes to apply to the template:

• Use the compare command

## use compare to identify change(s)
$ dotdrop compare --file=~/.vimrc

• Call update with the -P --show-patch switch that will provide with an ad-hoc solution to manually patch the template file using a temporary generated version of the template (this isn't a bullet proof solution and might need manual checking)

## get an ad-hoc solution to manually patch the template
$ dotdrop update --show-patch ~/.vimrc
[WARN] /home/user/dotfiles/vimrc uses template, update manually
[WARN] try patching with: "diff -u /tmp/dotdrop-sbx6hw0r /home/user/.vimrc | patch /home/user/dotfiles/vimrc"

• Install the dotfiles to a temporary directory (using the install command and the -t switch) and compare the generated dotfile with the local one.

## use install to identify change(s)
$ dotdrop install -t -t f_vimrc
Installed to tmp /tmp/dotdrop-6ajz7565
$ diff ~/.vimrc /tmp/dotdrop-6ajz7565/home/user/.vimrc

Remove dotfiles

The command remove allows to stop managing a specific dotfile with dotdrop. It will:

• remove the entry in the config file (under dotfiles and profile)
• remove the file from the dotpath

For more options, see the usage with dotdrop --help

Environment variables

Following environment variables can be used to specify different CLI options. Note that CLI switches take precedence over environment variables (except for DOTDROP_FORCE_NODEBUG)

• DOTDROP_PROFILE: -p --profile

export DOTDROP_PROFILE="my-fancy-profile"

• DOTDROP_CONFIG: -c --cfg

export DOTDROP_CONFIG="/home/user/dotdrop/config.yaml"

• DOTDROP_NOBANNER: -b --no-banner

export DOTDROP_NOBANNER=

• DOTDROP_DEBUG: -V --verbose

export DOTDROP_DEBUG=

• DOTDROP_FORCE_NODEBUG: disable debug outputs even if -V --verbose is provided or DOTDROP_DEBUG is set

export DOTDROP_FORCE_NODEBUG=
