The Comma Text Object

This is something that I have been missing in Vim. The comma text object makes it easy to modify parameter lists in C-like languages and other comma separated lists. It is basically the area between two commas or between a comma and a bracket. In the line shown in the illustration to the right, the three ranges this text object can span are highlighted in red.

Comma text object ranges. If the cursor is over, say, “arg2”, pressing c i , (“change inner comma”) would delete “double arg2” and place the cursor between the two commas in insert mode. A very convenient way to change a function’s parameters.

Emulated Vim Command Bar

Kate 4.11 introduced a hidden config option that make “/”, “?” and “:” bring up a new search/ command in place of the usual Kate Find/ Replace / Command-line bar. The bar is intended to intended to replicate many of the features of Vim’s command bar, and also to fix many of the issues with Kate Vim mode’s interaction with Kate’s Find/ Replace bar (interactive replace not working; incremental search not positioning the cursor correctly; not usable in mappings/ macros; etc).

The following shortcuts are provided by the emulated command bar; as with Vim, these can be remapped with cmap, cnoremap, etc:

. insert contents of register.
Insert word under the (document) cursor.
Invoke context-specific completion (see below)/ move back/ up in the completion list.
Move forward/ down in the completion list.
Kate Vim Extension. Auto-complete word from document.
Kate Vim Extension. In a sed-replace expression (i.e. one of the form s/find/replace/[g][c][i]), clear the “find” term and place the cursor there.
Kate Vim Extension. In a sed-replace expression (i.e. one of the form s/find/replace/[g][c][i]), clear the “replace” term and place the cursor there.
. Kate Vim Extension. As with ., insert the content of the named register, but escape it in such a way that when used with a search, we search for the literal content of the register; not the content of the register interpreted as a regex.

The “context-specific completion” is decided as follows:

  • In a search bar (“/” or “?”), auto-complete from search history (which includes searches initiated via “*” and “#”; searches done in sed-replace expressions; etc.)
  • In an empty command bar (“:”), auto-complete from command history (NB: auto-completion of command names is invoked automatically when you begin typing).
  • In a command-bar containing a sed-replace expression (e.g. “‘s/find/replace/gc”), if the cursor is positioned over “find”, auto-complete from the “search” history; if over the “replace”, auto-complete from the history of “replace” terms.

When executing a sed-replace expression in the command bar with the “c” flag (e.g. s/find/replace/gc), a Vim-style interactive search/replace expression will be initiated.

Some example usages of the emulated command bar, with GIF animations, are given in this blog. In 4.11, the emulated command bar can be enabled by setting the hidden config option “Vi Input Mode Emulate Command Bar” to “true”. in your katerc/ kwriterc/ kdeveloprc.

Missing Features

    As stated earlier, the goal of Kate’s VI Mode is not to support 100% of Vim’s features, however, there are some features which are sorely missed
  • Visual block mode – especially the ability to prepend/append text to the visual block selection.
  • Having ex commands available in other programs than the Kate application.
  • The search code needs improvement and the * and # commands should just be regular searches.

If you miss other features or want to help on the ones mentioned above, feel free to contact me or send patches! 🙂

  • t and made some formatting fixes
