Config

The config file used by dotdrop is config.yaml.

Location

Unless specified dotdrop will look in following places for the config file (config.yaml) and use the first one found

• current/working directory or the directory where dotdrop.sh is located if used
• ${XDG_CONFIG_HOME}/dotdrop/
• ~/.config/dotdrop/
• /etc/xdg/dotdrop/
• /etc/dotdrop/

You can force dotdrop to use a different file either by using the -c --cfg cli switch or by defining the DOTDROP_CONFIG environment variable.

Variables

Multiple variables can be used within the config file to parametrize following elements of the config:

• dotfiles src and dst paths (see Dynamic dotfile paths)
• external path specifications
  • import_variables
  • import_actions
  • import_configs
  • profiles's import

actions and transformations also support the use of variables but those are resolved when the action/transformation is executed (see Dynamic actions, Dynamic transformations and Templating).

Following variables are available in the config files:

• variables defined in the config
• interpreted variables defined in the config
• profile variables defined in the config
• environment variables: {{@@ env['MY_VAR'] @@}}
• dotdrop header: {{@@ header() @@}} (see Dotdrop header)

As well as all template methods (see Available methods)

Symlink dotfiles

Dotdrop is able to install dotfiles in three different ways which are controlled by the link config attribute of each dotfile:

• link: nolink: the dotfile (file or directory) is copied to its destination
• link: link: the dotfile (file or directory) is symlinked to its destination
• link: link_children: the files/directories found under the dotfile (directory) are symlinked to their destination

Dynamic dotfile paths

Dotfile source (src) and destination (dst) can be dynamically constructed using defined variables (variables and dynvariables).

For example to have a dotfile deployed on the unique firefox profile where the profile path is dynamically found using a shell oneliner stored in a dynvariable:

dynvariables:
  mozpath: find ~/.mozilla/firefox -name '*.default'
dotfiles:
  f_somefile:
    dst: "{{@@ mozpath @@}}/somefile"
    src: firefox/somefile
profiles:
  home:
    dotfiles:
    - f_somefile

Make sure to quote the path in the config file.

Dynamic actions

Variables (config variables and dynvariables and template variables) can be used in actions for more advanced use-cases.

dotfiles:
  f_test:
    dst: ~/.test
    src: test
    actions:
      - cookie_mv_somewhere "/tmp/moved-cookie"
variables:
  cookie_dir_available: (test -d /tmp/cookiedir || mkdir -p /tmp/cookiedir)
  cookie_header: "{{@@ cookie_dir_available @@}} && echo 'header' > /tmp/cookiedir/cookie"
  cookie_mv: "{{@@ cookie_header @@}} && mv /tmp/cookiedir/cookie"
actions:
  cookie_mv_somewhere: "{{@@ cookie_mv @@}} {0}"

or even something like this:

actions:
  log: "echo {0} >> {1}"
config:
  default_actions:
  - preaction '{{@@ _dotfile_key @@}} installed' "/tmp/log"
...

Make sure to quote the actions using variables.

Dynamic transformations

As for dynamic actions, transformations support the use of variables (variables and dynvariables and template variables).

A very dumb example:

trans_read:
  r_echo_abs_src: echo "{0}: {{@@ _dotfile_abs_src @@}}" > {1}
  r_echo_var: echo "{0}: {{@@ r_var @@}}" > {1}
trans_write:
  w_echo_key: echo "{0}: {{@@ _dotfile_key @@}}" > {1}
  w_echo_var: echo "{0}: {{@@ w_var @@}}" > {1}
variables:
  r_var: readvar
  w_var: writevar
dotfiles:
  f_abc:
    dst: ${tmpd}/abc
    src: abc
    trans_read: r_echo_abs_src
    trans_write: w_echo_key
  f_def:
    dst: ${tmpd}/def
    src: def
    trans_read: r_echo_var
    trans_write: w_echo_var

All dotfiles for a profile

To use all defined dotfiles for a profile, simply use the keyword ALL.

For example:

dotfiles:
  f_xinitrc:
    dst: ~/.xinitrc
    src: xinitrc
  f_vimrc:
    dst: ~/.vimrc
    src: vimrc
profiles:
  host1:
    dotfiles:
    - ALL
  host2:
    dotfiles:
    - f_vimrc

Ignore patterns

It is possible to ignore specific patterns when using dotdrop. For example for compare when temporary files don't need to appear in the output.

• for install
  • using instignore in the config file
• for compare
  • using cmpignore in the config file
  • using the command line switch -i --ignore
• for update
  • using upignore in the config file
  • using the command line switch -i --ignore

The ignore pattern must follow Unix shell-style wildcards like for example */path/to/file. Make sure to quote those when using wildcards in the config file.

Patterns used on a specific dotfile can be specified relative to the dotfile destination (dst).

config:
  cmpignore:
  - '*/README.md'
  upignore:
  - '*/README.md'
  instignore:
  - '*/README.md'
...
dotfiles:
  d_vim
    dst: ~/.vim
    src: vim
    upignore:
    - "*/undo-dir"
    - "*/plugged"
...

To completely ignore comparison of a specific dotfile:

dotfiles:
  d_vim
    dst: ~/.vim
    src: vim
    cmpignore:
    - "*"

To ignore specific directory when updating

dotfiles:
  d_colorpicker:
    src: config/some_directory
    dst: ~/.config/some_directory
    upignore:
      - '*sub_directory_to_ignore'
