Fixes#86
This allows the formula line to be evaluated, even if there is a single
empty line after the table. The "empty" line is allowed to contain
whitespace, but nothing else.
The formula will evaluate if triggered on the table, the empty line, or
the formula lines.
* Does not try to forcefully cast column content to float
* Silences any errors during formula evaluation, you can look at
`v:errmsg` to see if there was any error during the evaluation for
debugging
fixed a Vim error(E907) in Min/Max when comparing v:null to a float
fixed CountE/CountNE/PercentE/PercentNE to support spanning rows/columns
added test cases for all the new formula functions
- Min: get the lowest value
- Max: get the highest value
- CountE: count the number of empty cells
- CountNE: count the number of non-empty cells
- PercentE: percent of empty cells
- PercentNE: percent of non-empty cells
- AverageNE: average over non-empty cells
Also added a subtle tweak that ignores an HTML comment tag ('<!--')
found between the table and the starting formula line. Being able to
wrap all the formula lines with an HTML comment prevents the formulas
from being rendered in Markdown/ReST output.
If a g:table_mode_separator is escaped by a backslash, the table is
aligned ignoring this instance of the g:table_mode_separator, but the
column deletion and insertion functions did not consider this behaviour.
The g:table_mode_escaped_separator regex is simplified and optimized a
little bit. Also more care is taken to prevent unexpected behaviour if
special characters are used as g:table_mode_separator.
Readme mentions settings for Markdown and ReST, but we can apply them
automatically for the current filetype. If a user is editing a no
filetype scratch buffer, they'll still need to configure these options
themselves. But this provides better defaults when editing a buffer of
these filetypes.
Adds get_buffer_or_global_option that could be used for any other
buffer-local (filetype-specific) options.
Initial support. Alignment and border creation is fixed and is
consistent in considering the escaped table separator as part of the
column.
TODO :
* Fix syntax to reflect the above.
* Fix cell definition, motion & formula engine to incorporate this.
In order to use vim table mode over vimwiki native table formatting
support you need to add the following vimwiki settings to your vimrc :
```vim
let g:vimwiki_table_mappings=0
let g:vimwiki_table_auto_fmt=0
```
We now have support for center alignment, simply add a header border
with the `g:table_mode_align_char` as both the first and the last
character so it would look something like `+:.....:+` to center align
the column values.
* Fixed tablemode#spreadsheet#cell#SetCell() to accommodate the fact that we
can have borders anywhere in the table. Using
tablemode#spreadsheet#LineNr() to get get the line of the actual row
in the table.
* Fixed tablemode#spreadsheet#LineNr()
Added tablemode#logger#log && g:table_mode_verbose
Use logger wherever needed for logging general things, in future we can
scale this to do more things like write to a log file for debugging. It
uses g:table_mode_verbose to determine whether or not to actually log
the message.
Added a mapping `<Plug>(table-mode-sort)` which is mapped by default to
`<Leader>ts` that sorts the current table by the column in which the
cursor is currently.
Also added `TableSort` command that gives you a little more control over
the sorting, you can pass in additional :sort flags like u, i, n etc and
also use it with a `!` to sort in reverse order.
Altered table mode behavior such that if there is a header line, i.e.
the first line of the table is separated by a border with the rest of
the table, then it is not taken into account for formulas and cell
arithmetic
