Getting Started

Installation

There are 2 ways to do this

  1. I recommend installing pathogen.vim and then adding a git submodule for your plugin:

$ cd ~/.vim $ git submodule add git@github.com:dhruvasagar/vim-table-mode.git bundle/table-mode

2. Copy autoload/todomode.vim, plugin/todo-mode.vim, doc/todo-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 `|` 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 `<Leader>tm` 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.

- **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 `<Leader>tt` 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 `<Leader>T`
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 `<Leader>T` 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 `<Leader>t[hjkl]`
to move left | down | up | right cells respectively. You can use
`g:table_mode_map_prefix` option to define the prefix mapping to be used
before 'hjkl'. 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. By default
   it's `tc`, but that can be changed if you wish to by setting the
   `g:table_mode_cell_text_object` option.

   This is intelligent in the sense that if you use it to delete the
   contents it will delete everything till the `g:table_mode_separator` so
   that the cell is removed and you can enter new stuff if you wish to (had
   you used 'c' operator), having to input the `g:table_mode_separator`
   again to form the cell & realign it (since it can't be done from the
   text object itself). However if you were to 'y' or yank the text, it
   would copy the right text, i.e. the contents of the cell and nothing
   else.

- **Delete Row** :

   You can use the `<Leader>tdd` 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 `<Leader>tdc` 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 `<Leader>tfa`
 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 `<Leader>tfe` defined by the option `g:table_mode_eval_expr_map`
from anywhere inside the table or while on the formula line.

- **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.

   - `$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.

- 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`
