# Eclipse Project Management

The core concept in most IDEs is the that of a project, and Eclipse is no different. Since a project must exist before you can perform any of the more interesting tasks, eclim provides a set of commands to create and manage projects from within Vim.

For the commands below that accept a project name as an argument, you may use Vim’s command line completion to complete the project name.

    :ProjectSettings a_p<Tab>
    :ProjectSettings a_project

- :ProjectCreate <folder> [-p <project_name>] -n <nature> … [-d <project_dependency> …]

  - -p: Optional argument used to specify the project name. If omitted, eclim will use the last segment of the project’s path, with any spaces replaced with underscores, as the project name.

  - -n: Required argument which specifies a space separated list of project natures (java, php, etc.) to add to the project. If you want to create a project with no natures, you can use the word “none” here.

        :ProjectCreate ~/workspace/test -n none

    Note that eclim supports command completion of available nature names.

        :ProjectCreate ~/workspace/test -n p<tab>
        :ProjectCreate ~/workspace/test -n php

  - -d: Optional argument used to specify a space separated list of project names which the project you’re creating depends on.

  Some Examples

      :ProjectCreate ~/projects/a_project -n java
      :ProjectCreate ~/projects/a_project -n java -d another_project yet_another_project
      :ProjectCreate ~/projects/a_project -n java php -p My\ Project\ Name

- :ProjectImport <folder>

  If you have an existing eclipse project folder which does not exist as a project in your current workspace, you can import that project using this command:

      :ProjectImport ~/workspace/some_project

- :ProjectImportDiscover <folder>

  If you have several existing eclipse projects within a parent directory that you’d like to import, you can do so using this command, which scans the supplied folder for all `.project` files and imports the corresponding project into your current workspace:

      :ProjectImport ~/some/parent/dir

- :ProjectList

  Simply echo a list of available projects.

- :ProjectSettings [<project>]

  Opens a window with the project’s available settings. If a project name is supplied with this command, then the settings for that project are opened. If no project name is supplied, and the current file is in a project directory, then the settings for the current project will be opened.

  In the resulting window you can modify the values and save the changes by simply writing the file in the usual Vim manner (:w). The format of the buffer is in the standard properties file format as supported by java, so all the same rules apply when editing. You can refer to the settings documentation for a description of the available settings.

- :ProjectDelete <project>

  Deletes the project with the specified name.

- :ProjectRename [<project>] <name>

  Renames a project. If two arguments are supplied then the first argument is interpreted as the name of the project to rename and the second argument as the new name for the project. When only a single argument is supplied, then that argument is used as the new name for the project which the current file belongs to.

- :ProjectMove [<project>] <dir>

  Moves a project to the specified directory. If two arguments are supplied then the first argument is interpreted as the name of the project to move and the second argument as the directory to move the project to. When only a single argument is supplied, then that argument is used as the directory to move the current project to.

  Warning

  :ProjectMove, and possibly :ProjectRename, will result in the renaming of your project’s directory in the underlying file system. Eclim will do its best to reload any files that have moved as a result of the directory renaming and adjust your current working directory if necessary, but only for the current vim session. If you have other vim sessions open with files from the project, then eclim will be unable to reload those files in those sessions for you, so you will have to do so manually. A best practice would be to close any other vim sessions that might be affected by the moving or renaming of a project.

  Note

  When open files have moved as a result of :ProjectMove or :ProjectRename, eclim will reload those files in the current session, but it must do so via an :edit, which means that vim’s undo tree will be lost. However, you will still have access to the eclipse history.

- :ProjectRefresh [<project> <project> …]

  Refreshes the supplied list of named projects by synchronizing each project against the current files on disk. If no projects names are supplied, refresh the current project. Useful when files may have been added, removed, or updated by a secondary application, like a version control system (cvs, subversion, etc).

- :ProjectRefreshAll

  Refreshes all projects.

- :ProjectInfo [<project>]

  Echo info about the current or supplied project.

  Eclim supports displaying info about the current project in vim’s status line by adding a call to `eclim#project#util#ProjectStatusLine()` to your statusline option:

      set statusline=%<%f\ %M\ %h%r%=%-10.(%l,%c%V\ %{eclim#project#util#ProjectStatusLine()}%)\ %P

  By default, this will just include the project name, but you can customize the output by setting g:EclimProjectStatusLine:

      let g:EclimProjectStatusLine = 'eclim(p=${name}, n=${natures})'

- :ProjectOpen [<project>]

  Opens a closed project.

- :ProjectClose [<project>]

  Closes the current or supplied project. According to the Eclipse documentation, closing unused projects can reduce the amount of memory used, and may improve performance when building projects.

- :ProjectNatures [<project>]

  Echo list of natures for the supplied project name or for all projects if no project name specified.

- :ProjectNatureAdd <project> [<nature> …]

  Adds one or more natures to a project. Supports command line completion of nature names.

- :ProjectNatureRemove <project> [<nature> …]

  Removes one or more natures from a project. Supports command line completion of nature names.

- :ProjectProblems[!] [<project>] Populates vim’s quickfix with a list of all eclipse build errors and warnings for the current, or specific project, and all related projects. Very similar to eclipse’s “Problems” view. By default, if the current quickfix list represents a problems list, then as you save source files this list will be updated accordingly.

  Appending ‘!’ limits the problem results to just errors.

  Note

  Problems are only reported for those projects that have an associated builder in their .project file. If a project is not reporting errors, first check that a proper builder is present in the .project file. For java projects created via eclim prior to eclim 1.5.2, the java builder may be missing, so you’ll need to recreate the project, at which time eclim will add the java builder.

  Configuration

  Vim Settings

  - g:EclimQuickFixOpen (Default: ‘botright copen’)

    Specifies the command used to open the quickfix window when executing the :ref`:ProjectProblems` command.

  - g:EclimProjectProblemsUpdateOnSave (Default: 1)

    When non 0, indicates that the problems list should be updated when saving source files, but only if the quickfix list currently represents a problems list.

  - g:EclimProjectProblemsUpdateOnBuild (Default: 1)

    When non 0, indicates that the problems list should be updated after a :ProjectBuild, but only if the quickfix list currently represents a problems list.

- :ProjectBuild [<project>]

  Builds the current or supplied project.

- :ProjectRun [<launch_config_name>]

  Runs an eclipse launch configuration. When no launch configuration name is supplied, the first available launch configuration will be used.

  Before you can run this command, you must first start vim with the `--servername` argument (eclimd currently sends the process stdout and stderr to vim using vim’s remote invocation support):

      $ vim --servername run ...

  When your launch configuration is executed, a temporary buffer will be opened in vim to display any output. When you close this window the launch configuration process will be terminated. You can also terminate the process from within the temporary output buffer by running the `:Terminate` command (only available from that window). Also note that if you close vim, any running launch configurations will be terminated.

- :ProjectRunList

  Print a list of available eclipse launch configurations for the current project.

- :ProjectCD

  Changes the global current working directory to the root directory of the current file’s project (executes a :cd).

- :ProjectLCD

  Changes the current working directory of the current window to the root directory of the current file’s project (executes a :lcd).

- :ProjectTree [<project> <project> …]
  :ProjectTree <dir> [<dir> <project> …]

  Opens a window containing a navigable tree for the root directory of one or more projects. If no arguments are supplied, the resulting tree is for the current project. Otherwise, the tree contains multiple root nodes, one for each project root directory. The command also supports one or more arbitrary directories as arguments as well should you want to open a tree for a project not managed by eclim/eclipse (Note: the last part of the path will be used as the project’s name).

  Available key mappings in project tree window.

  - <cr> - Toggles expansion / collapsing of a directory, or executes the first available action for a file.
  - E - Opens the current file using ‘edit’ in the content window.
  - S - Opens the current file in a new split.
  - | (pipe) - Opens the current file in a new vertical split.
  - T - Opens the current file in a new tab.
  - o - Toggles folding / unfolding of a directory, or opens a window of available actions to be executed on the selected file. Hitting <enter> on an entry in the action window will execute that action on the current file.
  - s - Executes :shell for the directory under the cursor or the parent directory of the file under the cursor.
  - R - Refreshes the current directory against the current state of the file system.
  - A - Toggles whether or not hidden files are displayed in the tree.
  - ~ - Changes the root node to the current user’s home directory.
  - C - Changes the root node to the directory under cursor.
  - B - Changes the root node to the parent directory of the current root node.
  - K - Changes the root node to the root path which will be either the project root or the file system root.
  - p - Moves the cursor to the parent of the node under the cursor.
  - P - Moves the cursor to the last child of the nearest open directory.
  - :CD <dir> - Changes the root to the supplied directory.
  - D - Prompts you for a directory name to create, pre-filled with the directory path in the tree where this mapping was executed.
  - F - Prompts you for a new or existing filename to open, pre-filled with the directory path in the tree where this mapping was executed.
  - Y - Yanks the path of the current file/directory to your clipboard.
  - ? - View the help buffer

  Configuration

  Vim Settings

  - g:EclimProjectTreeAutoOpen (Default: 0)

    When non 0, a project tree window will be auto opened for new Vim sessions or new tabs in existing sessions if the current file is in a project.

  - g:EclimProjectTreeAutoOpenProjects (Default: [‘CURRENT’])

    List of project names that will be in the project tree when it is auto opened. The special name ‘CURRENT’ represents the current project of the file being loaded in Vim when the tree is auto opened.

  - g:EclimProjectTreeExpandPathOnOpen (Default: 0)

    When non 0, the path of the current file will be expanded in the project tree when the project tree window is opened.

  - g:EclimProjectTreePathEcho (Default: 1)

    When non 0, the root relative path of the node under the cursor will be echoed as you move the cursor around.

  - g:EclimProjectTreeSharedInstance (Default: 1)

    When non 0, a tree instance with the same list of projects will be shared across vim tabs. This allows you to have the same project tree open in several tabs all with the same state (with the exception of folds).

  - g:EclimProjectTreeActions

    Default:

        let g:EclimProjectTreeActions = [
            \ {'pattern': '.*', 'name': 'Split', 'action': 'split'},
            \ {'pattern': '.*', 'name': 'Tab', 'action': 'tabnew'},
            \ {'pattern': '.*', 'name': 'Edit', 'action': 'edit'},
          \ ]

    List of mappings which link file patterns to the available actions for opening files that match those patterns. Note that the first mapping is the list is used as the default (<cr>).

  Note

  ProjectTree honors vim’s ‘wildignore’ option by filtering out files matching those patterns from the tree. The ‘A’ mapping will toggle the display of those files along with other hidden files and directories.

- :ProjectTreeToggle

  Toggles (opens/closes) the project tree for the current project.

- :ProjectsTree

  Similar to :ProjectTree but opens a tree containing all projects.

- :ProjectTab <project>
  :ProjectTab <dir>

  Command to initialize a new vim tab with the project tree open and the tab relative working directory set to the project root. This allows you to work on multiple projects within a single vim instance where each project is isolated to its own tab. The command also supports an arbitrary directory as an argument instead of a project name should you want to open a tab for a project not managed by eclim/eclipse (Note: the last part of the path will be used as the project’s name).

  Configuration

  Vim Settings

  - g:EclimProjectTabTreeAutoOpen (Default: 1)

    When non 0, the project tree window will be auto opened on the newly created tab.

- :ProjectGrep /<pattern>/ <file_pattern> [<file_pattern> …]

  Executes vimgrep using the supplied arguments from the root of the current project allowing you to run a project wide grep from any file within the project.

- :ProjectGrepAdd /<pattern>/ <file_pattern> [<file_pattern> …]

  Just like :ProjectGrep but using vimgrepadd instead.

- :ProjectLGrep /<pattern>/ <file_pattern> [<file_pattern> …]

  Just like :ProjectGrep but using lvimgrep instead.

- :ProjectLGrepAdd /<pattern>/ <file_pattern> [<file_pattern> …]

  Just like :ProjectGrep but using lvimgrepadd instead.

- :ProjectTodo

  Searches all the source files in the project (those with extensions included in g:EclimTodoSearchExtensions) for the fixme / todo pattern (defined by g:EclimTodoSearchPattern) and adds all occurrences to the current location list.

- :Todo

  Just like :ProjectTodo, but limits the searching to the current file.

  Configuration

  Vim Settings

  - g:EclimTodoSearchPattern

    Default:

        let g:EclimTodoSearchPattern = '\(\<fixme\>\|\<todo\>\)\c'

    Defines the regex pattern used to identify todo or fixme entries.

  - g:EclimTodoSearchExtensions

    Default:

        let g:EclimTodoSearchExtensions = ['java', 'py', 'php', 'jsp', 'xml', 'html']

    Defines a list of file extensions that will be searched for the todo / fixme entries.
