* *
* Macro complete.the V1.3 (THE) *
* *
* Author: Pablo Garcia-Abia *
* Date: 14/01/98 *
* *
* Syntax: complete alternative_command *
* *
* *
* Description: *
* *
* Macro to complete filenames in the command line, whenever the *
* first command typed is one of the following: *
* *
* XEDIT FFILE FILE MACRO LS *
* THE SSAVE SAVE OSREDIR DIRECTORY *
* EDIT GET PUTD STATUS *
* *
* Otherwise, an alternative command is executed. *
* *
* When the filename is being typed in the command line, a double *
* equal sign (==) is always substituted by the whole filename *
* (without path) of the file being edited. *
* *
* A single equal sign (=) in a given field (delimitied by the *
* selected separator) is substituted by the corresponding field *
* of the filename of the file being edited. *
* *
* The separator is taken as the character preceding the equal *
* sign unless it is the first in the string. In that case, the *
* character following the '=' is taken as separator. The dot *
* '.' is used as a separator in ill cases. *
* *
* More sophisticated completion may be implemented in the future *
* for other commands, eventually. *
* *
* *
* Example: *
* *
* To use it, define a key in the following way: *
* *
* DEFINE keyname MACRO complete alternative_command *
* *
* For example: *
* *
* define TAB macro complete sos tabfieldf *
* *
* In this example, the TAB key will complete filenames when typed *
* IN the CMDline (after XEDIT, THE or any other allowed command). *
* Otherwise it will execute "sos tabfieldf". *
* *
* *
* Note: more sophisticated completion may be implemented in the *
* future for other commands, eventually. *
* *
* *
* Version history: *
* *
* 1.3 (14/01/98) - follow up directory tree when looking for *
* completions: UNIX ok, to be checked in OS2. *
* Not implemented in other OS. *
* - FJW: OS-dependent corrections (thanks) *
* - substitution of '=' and '==' *
* 1.2 (11/12/97) added list of commands allowed for file completion *
* 1.1 (10/12/97) bug on ambiguities output corrected *
* 1.0 (10/12/97) first version *
* *
* Bugs, comments and/or questions to Pablo.Garcia.Abia@cern.ch *
