Description:Displays differences of two text files using MUI window
Developer/Porter:Stéphane Saragaglia
Short: Displays differences of two text files in a MUI window
Uploader: saragaglia@ifrance.com (Stephane SARAGAGLIA)
Author: saragaglia@ifrance.com (Stephane SARAGAGLIA)
Type: dev/misc
Requires: AmigaOS3.x or MorphOS, MUI, aminet/dev/mui/MCC_TextEditor.lha, aminet/dev/mui/MCC_Toolbar.lha, diff cmd
Version: 1.0

AMuiDiff is a MUI based diff tool which compares couple of text files.
It is a GUI for diffutils commands...
This tool is free. There is no copyright.


lha x amuidiff.lha

Copy the amigaos version (amuidiff.aos) or the morphos version (amuidiff.mos) in C: .
Copy the french catalog in locale:Catalogs/fran�ais/, or AMuiDiff speaks

AMuidiff needs the MUI TextEditor and ToolBar classes (YAM, ...) :
- aminet/dev/mui/MCC_TextEditor.lha
- aminet/dev/mui/MCC_Toolbar.lha

AMuiDiff needs a diff command tool. The following have been successfully tested :
- aminet/util/gnu/HWGdiffP1_2_6.lha (SAS port)
- GG diffutils

The source is provided. Go to the "src/core" directory, and perform "make" to
compile the morphos version, and "make amigaos" to compile the amigaos (68k)
version. AMuiDiff has been compiled using GCC. Compilation problems could
occur using other compiler... I will try to perform some tests with other

To use the Editor feature, the AMuiDiff/EDITOR env var has to be set, or
golded:golded will be used :
- setenv "AMuiDiff/EDITOR" the_editor_you_want
- copy ENV:AMuiDiff ENVARC:AMuiDiff

To make AMuiDiff uses fixed font, the AMuiDiff/FIXEDFONT env var has to be set
to TRUE :
- setenv "AMuiDiff/FIXEDFONT" TRUE
- copy ENV:AMuiDiff ENVARC:AMuiDiff


AMuiDiff can be launched from WB or cli.
Cli options are : FILE1,FILE2,OPTIONS,DEBUG/S
FILE1 and FILE2 : strings : files to compare
OPTIONS : strings : diff options.
Ex : AMuiDiff.mos ss_amiga_lib_tools.c ss_lib_tools.c OPTIONS="-b"
Ignore changes in the amount of white space
DEBUG : switch : amuidiff generate error log messages you can send me ;)

When the window is opened, it is easy to use...


I currently use AMuiDiff with CVS using this script :
.KEY file

echo "--> executing : cvs update -p <file> >T:cvs_amuidiff"
cvs update -p <file> >T:cvs_amuidiff
AMuidiff T:cvs_amuidiff <file>
delete T:cvs_amuidiff

So to compare a file with its cvs archived version, I invoke :
> cvs-diff file_modified.


In priority order :
- Correct bugs users could discover : Permanent
- directory diffs management : In next release
- Drag'n'Drop to load files : OK
- Edit files from GUI : OK
- Confirm or correct diffs from one
file to the other (merge) : Planned
- Clean the source ! : Permanent
- Correct the AOS bug of the virtualgroup which
prevents the user from selecting text on the right
view or from clicking on arrows when the left
virtgroup is too large : investigation needed
