Only after doing this, and if the command is still not in the + path, then print "Command not found.". I realize there are some + extreme cases in which this is suboptimal, but in most cases with + normal users this would be a big win, and simplify the manual and + perhaps even the code. + _________________________________________________________________ + + Wish "tcsh -l" would accept other flags. At least "-c". + + Currently I can't get ssh to have the right environment unless it is a + login shell. The .ssh/environment doesn't work for me because I login + to different machines with different environments.

Setting a temporary environment variable before executing + the command would also work and would probably be safer. + + Perhaps this info is already available as a special variable that can + be manually passed to the script: complete prog 'n/-x/`myscript + $cmd_line`'? + + Update: I looked into this further by actually downloading the code + and looking through it. It doesn't seem that this information is + available anywhere, but I did manage to achieve what I wanted by + adding the following two lines around the call to tw_complete (line + 278, tw.parse.c 6.12.00): + + added> tsetenv(STRCURRCMDLINE, (Char *)&qline); + looking = tw_complete(cmd_start, &wordp, &pat, looking, &suf); + + added> Unsetenv(STRCURRCMDLINE); + + And I added a definition for STRCURRCMDLINE to be "CURRCMDLINE". + + This provides the environment variable CURRCMDLINE to any + script/program running under complete. The only issue I see is picking + a sufficiently obscure environment variable that noone else is likely + to use, but have it readable enough to understand what it is for. It + also shouldn't overwrite an existing ENV variable if it is already in + use. _________________________________________________________________ Home | RecentChanges | Preferences Edit text of this page | View other revisions - Last edited April 28, 2001 2:04 (diff) + Last edited March 25, 2004 10:27 (diff) Search: ____________________ |
