/*
|
|
* When adding an Ex command:
|
|
* 1. Add an entry to the table in src/nvim/ex_cmds.lua. Keep it sorted on the
|
|
* shortest version of the command name that works. If it doesn't start with
|
|
* a lower case letter, add it at the end.
|
|
*
|
|
* Each table entry is a table with the following keys:
|
|
*
|
|
* Key | Description
|
|
* ------- | -------------------------------------------------------------
|
|
* command | Name of the command. Required.
|
|
* enum | Name of the enum entry. If not set defaults to CMD_{command}.
|
|
* flags | A set of the flags from below list joined by bitwise or.
|
|
* func | Name of the function containing the implementation.
|
|
*
|
|
* Referenced function should be either non-static one or defined in
|
|
* ex_docmd.c and be coercible to ex_func_T type from below.
|
|
*
|
|
* All keys not described in the above table are reserved for future use.
|
|
*
|
|
* 2. Add a "case: CMD_xxx" in the big switch in ex_docmd.c.
|
|
* 3. Add an entry in the index for Ex commands at ":help ex-cmd-index".
|
|
* 4. Add documentation in ../doc/xxx.txt. Add a tag for both the short and
|
|
* long name of the command.
