This help file is associated with the getfile.tcl routines, which
|
| 4 |
produce a screen for browsing and naming files.

.Directory.Intro
|
| 7 |
|
| 8 |
The current directory may be set either by choosing a new directory
|
| 9 |
by double-clicking on a directory in the file window, or by
|
| 10 |
explicitly changing the directory named in the entry window.
|
| 11 |
|
| 12 |
A directory may be given absolutely,
|
| 13 |
relative to the current path, or relative to your home directory or
|
| 14 |
that of another user using the tilde (~) shorthand.
|
| 15 |
|
| 16 |
Hitting <return> in the directory entry window has the same effect as
|
| 17 |
pressing the "List" button.
|
| 18 |
That is, the interface changes to that directory and lists all files
|
| 19 |
matching the given pattern(s).
|
| 20 |
|
| 21 |
If an attempt is made to change to a non-existent or read-protected
|
| 22 |
directory, an error message is printed in red and the interface
|
| 23 |
returns to the previously selected directory.
|
| 24 |
|
| 25 |
Hitting <return> in a list window is equivalent to double-clicking.
|
| 26 |
|
| 27 |
.Directory.Match
|
| 28 |
|
| 29 |
One or more matching (i.e. globbing) patterns may be given in this window,
|
| 30 |
separated by white spaces.
|
| 31 |
|
| 32 |
Nothing or a single asterisk (*) matches all files in
|
| 33 |
this directory.
|
| 34 |
Whatever the selected pattern, directories will always be listed,
|
| 35 |
followed by a slash (/).
|
| 36 |
This makes changing directories more convenient.
|
| 37 |
|
| 38 |
To list files beginning with a period (.), use the ".*" pattern.
|
| 39 |
Thus, it is possible to include all files in the directory listing by
|
| 40 |
entering ".* *" in the pattern window.
|
| 41 |
|
| 42 |
Hitting <return> in the pattern entry window has the same effect as
|
| 43 |
pressing the "List" button.
|
| 44 |
|
| 45 |
.Directory.List
|
| 46 |
|
| 47 |
The "List" button causes the interface to change to the selected
|
| 48 |
directory and list all files there matching the given pattern(s).
|
| 49 |
|
| 50 |
The same effect may be achieved by hitting <return> in either the
|
| 51 |
directory entry or pattern entry window.
|
| 52 |
|
| 53 |
.File.Intro
|
| 54 |
|
| 55 |
The file list box shows all files in the given directory matching the
|
| 56 |
specified pattern(s).
|
| 57 |
In addition, all subdirectories and the parent directory are listed
|
| 58 |
unconditionally.
|
| 59 |
|
| 60 |
Double-clicking on a directory in the file list box is the most
|
| 61 |
convenient method of filesystem navigation.
|
| 62 |
|
| 63 |
Clicking on a file selects it for editing, but does not enter it.
|
| 64 |
Double-click on a file if you wish to enter it.
|
| 65 |
|
| 66 |
.File.Entry
|
| 67 |
|
| 68 |
The file entry field allows you to enter the name of a file that may
|
| 69 |
or may not exist in the current directory.
|
| 70 |
|
| 71 |
Hitting <return> in this field is equivalent to
|
| 72 |
pressing the "OK" button (if it exists).
|
| 73 |
|
| 74 |
.File.View
|
| 75 |
|
| 76 |
The "View" button, if it exists, permits you to edit the highlighted
|
| 77 |
file from the directory listing, using either xedit or the editor
|
| 78 |
indicated by the EDITOR environment variable, if defined.
