This commit adds LiveEasyAlign command. (The name was chosen not to introduce
ambiguity when typing in only the prefix of the command: e.g. `:EasyA*|`)
In live interactive mode, the selected text is aligned on-the-fly as the user
type in. In order to finalize the alignment, the user has to type in the
same delimiter key again. (Or CTRL-X on regular expressions)
By default, unmatched trailing token from each line is also aligned in
right and center alignment modes unlike in left alignment mode. If
ignore_unmatched option is explicitly set to 1 by user, they will be ignored
even in right/center modes.
With this commit, we can now change option values in interactive mode with the
folowing special keys
- CTRL-L left_margin
- CTRL-R right_margin
- CTRL-D delimiter_align
- CTRL-I indentation
- CTRL-U ignore_unmatched
- CTRL-G ignore_groups
('ignores' option has been renamed to 'ignore_groups', but backward-compatible)
With this commit you can right-align the last token with * or ** field number.
For example, the following lines
a = 1
bb = 22
ccc = 333
are aligned as follows on `:EasyAlign**=`
a = 1
bb = 22
ccc = 333
And even if we don't have the second =, we can do `:EasyAlign!2=` to get
a = 1
bb = 22
ccc = 333
Unmatched line is NOT ignored on right-justification mode. However this
commit makes such a line ignored when the end of the line is highlighted
as one of the ignored syntax groups (e.g. Comments or Strings)
- Preserve indentation when a line starts with a delimiter
- Useful for aligning multi-line method chains
- Renamed `margin_{left,right}` to `{left,right}_margin
- Makes it easier to type in (`l`, `r`)
- `margin_{left,right}` is still supported
- Margins can be specified as the number of spaces, or as an arbitrary string
