Generic File Name Operations
GetGenericFileName:
PROC [opRope, fileName, wDir, defaultExt: Rope.
ROPE, illegalExts:
LIST
OF Rope.
ROPE, router: MsgRouter, emergency:
BOOL ¬
FALSE]
RETURNS [fullName: Rope.
ROPE ¬
NIL, success:
BOOL ¬
TRUE, versionSpecified:
BOOL ¬
FALSE];
Given fileName (provided by a user perhaps) and a working directory, expands the filename in that directory, adding the default extension if none was provided. It reports any problems onto the feedback stream unless emergency = TRUE. If there are any problems, success is set to FALSE and a complaint on behalf of the opRope is posted. Otherwise, the resulting full path name is returned.
FNameToGName:
PROC [name: Rope.
ROPE]
RETURNS [Rope.
ROPE];
Takes a local name like "[]<>Users>Bier.pa>Gargoyle>Foo" into a global name like "[QueenFish]<Cedar>Users>Bier.pa>Gargoyle>Foo".
FilenameMinusExtension: PROC [wholeName: Rope.ROPE] RETURNS [firstPart: Rope.ROPE];
Convenience File Name Operations for Gargoyle Use
GetInterpressFileName:
PROC [opRope, ipName: Rope.
ROPE, currentWDir: Rope.
ROPE, router: MsgRouter]
RETURNS [fullName: Rope.
ROPE ¬
NIL, success:
BOOL ¬
TRUE];
[fullName, success, ----] ← GetGenericFileName[opRope, ipName, currentWDir, "IP", LIST["gargoyle", "script", "mesa", "tioga"], feedback];
GetGargoyleFileName:
PROC [opRope, ggName: Rope.
ROPE, currentWDir: Rope.
ROPE, router: MsgRouter, emergency:
BOOL ¬

RETURNS [fullName: Rope.
ROPE ¬
NIL, success:
BOOL ¬

BOOL ¬

[fullName, success, versionSpecified] ← GetGenericFileName[opRope, ggName, currentWDir, "gargoyle", LIST["IP", "interpress", "script", "mesa", "tioga"], feedback, emergency];
GetScriptFileName:
PROC [opRope, scriptName: Rope.
ROPE, currentWDir: Rope.
ROPE, router: MsgRouter]
RETURNS [fullName: Rope.
ROPE ¬
NIL, success:
BOOL ¬
TRUE];
[fullName, success, ----] ← GetGenericFileName[opRope, scriptName, currentWDir, "script", LIST["gargoyle", "IP", "interpress", "mesa", "tioga"], feedback];
Generic File Opening Operations
OpenInterpressOrComplain: PROC [opRope: Rope.ROPE, router: MsgRouter, fullName: Rope.ROPE] RETURNS [ipMaster: InterpressInterpreter.Master, success: BOOL];
