Hi all,
While there are still some bugs left, I'm quite happy how structural
regexp support for vis is progressing. Known issues include:
- relative line specifiers are in some cases wrongly interpreted,
as a consequence -0+,+0- rounds dot up instead of down to whole
lines
- s (substitute) is implemented in terms of sed(1) called without any
arguments, hence:
* the count in s2/foo/bar is not supported
* it defaults to basic regular expression syntax whereas the rest of
vis uses the extended variation. Specifying which kind of regexp
to use doesn't seem portable (GNU sed uses -r, BSD -E, POSIX does
not specify it). As a result this requires ugly escaping:
s/\(a\),\(b\)/\2,\1/ instead of simply s/(a),(b)/\2,\1/ as is
possible in sam.
This particular case can be achieved by means of selection content
rotation in vis, but still it is an ugly inconsistency which should
be fixed at some point. All of vis should use the same regex syntax.
- multiple file support is still completely untested/broken
- with the current command prompt it is kind of hard to enter multi line
commands. It is possible by using <C-v><Enter> to insert a literal
newline. To execute the command it has to be selected, <Enter> then
executes the active selection.
- grouped commands { .. } do not operate on the same (initial) text state.
As previously discussed in this thread this will likely remain that way
for the foreseeable future.
It would be nice to get some more feedback, what annoys you the most?
Current git master can be considered as a release candidate of vis-0.3:
