# VIM Table Mode v4.6.2 [![Build Status](https://travis-ci.org/dhruvasagar/vim-table-mode.png?branch=master)](https://travis-ci.org/dhruvasagar/vim-table-mode)

An awesome automatic table creator & formatter allowing one to create neat
tables as you type.

## Change Log
See <a
href="https://github.com/dhruvasagar/vim-table-mode/blob/master/CHANGELOG.md">
CHANGELOG.md </a>

## Getting Started
### Installation

There are several ways to do this

1. I recommend installing <a
   href="https://github.com/Shougo/neobundle.vim">NeoBundle</a> and then just
   add `NeoBundle 'dhruvasagar/vim-table-mode'` to your ~/.vimrc

2. If you are using <a
   href="https://github.com/tpope/vim-pathogen">pathogen.vim</a>, then
   add a git submodule for your plugin:

   ```sh
$ cd ~/.vim
$ git submodule add git@github.com:dhruvasagar/vim-table-mode.git bundle/table-mode
   ```
3. Copy autoload/tablemode.vim, plugin/table-mode.vim, doc/table-mode.txt to
   respective ~/.vim/autoload/, ~/.vim/plugin and ~/.vim/doc under UNIX or 
   vimfiles/autoload/, vimfiles/plugin/ and vimfiles/doc under WINDOWS and
   restart VIM

### Usage

- **On the fly table creation** :

   By default the table column separator is <kbd>|</kbd> defined by the
   `g:table_mode_separator` option. As soon as you type it on a new line (ignores
   indentation) the script gets to work on creating a table around it. As you
   type and define more columns, the table is completed, formatted and aligned
   automatically on the fly.

   Since this could lead to unwanted behavior I have disabled table mode by
   default. You have to use `:TableModeToggle` command or the table mode
   toggle mapping, which is <kbd>\<Leader\>tm</kbd> defined by `g:table_mode_toggle_map`
   option to toggle the table mode or you can directly use `:TableModeEnable`
   and `:TableModeDisable` to enable or disable the table mode. This is on a
   per buffer basis and so it does not cause any unusual behavior unless it is
   enabled explicitly. Please read `:h table-mode` for further information.

   You can also define in a table header border how it's content should be
   aligned, whether right or left by using a `:` character defined by
   `g:table_mode_align_char` option.

- **Format existing content into a table** :

   Table Mode wouldn't justify it's name if it didn't allow formatting
   existing content into a table. And it does as promised. Like table creation
   on the fly as you type, formatting existing content into a table is equally
   simple. You can visually select multiple lines and call `:Tableize` on it,
   or alternatively use the mapping <kbd>\<Leader\>tt</kbd> defined by the
   `g:table_mode_tableize_map` option which would convert CSV (Comma Separated
   Value) data into a table and use `,` defined by `g:table_mode_delimiter`
   option as the delimiter.

   If however you wish to use a different delimiter, you can use the command
   `:Tableize/{pattern}` in a similar fashion as you use tabular (eg.
   `:Tableize/;` uses ';' as the delimiter) or use the mapping <kbd>\<Leader\>T</kbd>
   defined by `g:table_mode_tableize_op_map` option which takes input in the
   cmd-line and uses the `{pattern}` input as the delimiter.

   `:Tableize` also accepts a range and so you can also call it by giving
   lines manually like `:line1,line2Tableize`, but this is not very intuitive.
   You can use the mapping <kbd>\<Leader\>T</kbd> with a `[count]` to apply it to the
   next `[count]` lines in standard vim style.

- **Move between cells** :

   Now you can move between cells using table mode motions <kbd>[|</kbd>,
   <kbd>]|</kbd>, <kbd>{|</kbd> & <kbd>}|</kbd> to move left | right | up |
   down cells respectively. The left | right motions wrap around the table
   and move to the next | previous row after the last | first cell in the
   current row if one exists. 

- **Manipulating Table** :

  - **Cell Text Object** :

      Tableize provides a text object for manipulating table cells. Following
      the vim philosophy the you have <kbd>i|</kbd> & <kbd>a|</kbd> for the
      inner and around (including the immidiate right table separator) the
      table cell.

  - **Delete Row** :

      You can use the <kbd>\<Leader\>tdd</kbd> mapping defined by the option
      `g:table_mode_delete_row_map` to delete the current table row (provided
      you are within a table row), this can be preceeded with a [count] to
      delete multiple rows just like you would with 'dd'.

  - **Delete Column** :

      You can use the <kbd>\<Leader\>tdc</kbd> mapping defined by the option
      `g:table_mode_delete_column_map` to delete the entire current column
      (provided you are within a table row), this can also be preceeded with a
      [count] to delete multiple columns.

- **Table Formulas** :

  Table Mode now has support for formulas like a spreadsheet. There are 2 ways
  of defining formulas :

  - You can add formulas using `:TableAddFormula` or the mapping <kbd>\<Leader\>tfa</kbd>
    defined by the option `g:table_mode_add_formula_map` from within a table
    cell, which will ask for input on the cmd-line with a `f=` prompt. The
    input formula will be appended to the formula line if one exists or a new
    one will be created with the input formula taking the current cell as the
    target cell. The formula line is evaluated immidiately to reflect the
    results.

  - You can directly add / manipulate formula expressions in the formula line.
    The formula line is a commented line right after the table, beginning with
    'tmf:' (table mode formula). eg) `# tmf: $3=$2*$1`.  You can add multiple
    formulas on the line separated with a ';' eg) `# tmf: $3=$2*$1;$4=$3/3.14`

  You can evaluate the formula line using `:TableEvalFormulaLine` or the
  mapping <kbd>\<Leader\>tfe</kbd> defined by the option `g:table_mode_eval_expr_map`
  from anywhere inside the table or while on the formula line.

  NOTE: You can now use the mapping <kbd>\<Leader\>t?</kbd>

- **Formula Expressions** :

  Expressions are of the format `$target = formula`.

  - The `target` can be of 2 forms :

      - `$n`: This matches the table column number `n`. So the `formula` would
        be evaluated for each cell in that column and the result would be placed
        in it. You can use negative indice to represent column relative to the
        last, -1 being the last.

      - `$n,m`: This matches the table cell n,m (row, column). So in this case
        the formula would be evaluated and the result will be placed in this
        cell. You can also use negative values to refer to cells relative to
        the size, -1 being the last (row or column).

  - The `formula` can be a simple mathematical expression involving cells
    which are also defined by the same format as that of the target cell.  You
    can use all native vim functions within the formula. Apart from that table
    mode also provides 2 special functions `Sum` and `Average`. Both these
    functions take a range as input. A range can be of two forms :

      - `r1:r2`: This represents cells in the current column from row `r1`
        through `r2`. If `r2` is negative it represents `r2` rows above the
        current row (of the target cell).

      - `r1,c1:r2,c2`: This represents cells in the table from cell r1,c1
        through cell r2,c2 (row, column).

  - Examples :
      - `$2 = $1 * $1`
      - `$2 = pow($1, 5)` NOTE: Remember to put space between the $1, and 5
        here otherwise it will be treated like a table cell.
      - `$2 = $1 / $1,3`
      - `$1,2 = $1,1 * $1,1`
      - `$5,1 = Sum(1:-1)`
      - `$5,1 = float2nr(Sum(1:-1))`
      - `$5,3 = Sum(1,2:5,2)`
      - `$5,3 = Sum(1,2:5,2)/$5,1`
      - `$5,3 = Average(1,2:5,2)/$5,1`
