Eventually, at the user's +discretion, this editor buffer can be saved into a Makefile. +(Optionally, the user can also edit the buffer directly, so it acts as +a simple text editor.) + +While the Programmer's Notepad 2 (PN2) editor that ships with WinAVR +intends to eventually implement this functionality some day, there are +two reasons for this little project: + +. Act as a stop-gap measure so users will get something they can use + right now, without waiting any longer. + +. Since this tool is written in Tcl/Tk, it is also portable to Unix + systems, so Unix users (who'd never benefit from PN2) might use it. + +I do explicitly /not/ intend to make this tool the all-singing +all-dancing scriptable Makefile generator that can emit any Makefile +for any processor and compiler on earth. I really do not want to +spend that many more hours into it, it was intented to be a quick and +(hopefully not so) dirty tool that gets finished within a couple of +evenings, and won't cost me another dozen of hours per months for +supporting it, adding new features etc. If you feel this is worth +porting somewhere else (like for the MSP430-GCC that is probably +fairly close to AVR-GCC in terms of typical use), please pick it up, +extend it, and maintain it separately. As always, I appreciate +feedback, but reserve the right to ignore anything that tries to +extend this tool above the outlined original purpose. + +Note that the Makefile template as shipped requires GNU make for +various things (automagic dependency generation, some inference rules +are written in gmake syntax as well). However, as Mfile only relies +on a few macro names in the template, it should be relatively easy to +modify the template for other »make« dialects. The template (or input +file upon »File -> Open«) will be parsed when reading it, and only +those features actually present will be displayed in the »Makefile« +menu. So if e. g. people don't want to include AVRdude features, they +can delete all related lines from the template. Also if someone (like +Unix users, in particular those not using GNU make) want to modify the +way the dependencies are generated (e. g. by using the traditional +»make depend« approach), this should be completely unrelated. + + +Prerequisites +------------- + +Requires the Tcl and Tk toolkits in recent versions (no exact version +known, probably any 8.x version is OK). Current WinAVR (20030913) +contains these tools. + +As an alternative to the standard Tk wish interpreter, the tix +toolkit's tixwish interpreter can be used. Under Unix systems, the +look & feel is then closer to what Tk wish looks like under Windows. + + +Installation on Windows +----------------------- + +[Users of WinAVR 20040404 and beyond do get Mfile pre-installed. See +below for upgrade instructions.] + +Extract the archive into a subdirectory of its own, e. g. + +c:\WinAVR\mfile + +Double-click on the icon for »mfile.tcl« in your file browser +(explorer), and tell it to use c:\WinAVR\bin\wish84.exe to run this +file. (Adjust appropriately if you installed WinAVR in another +directory.) + +Since Windows always changes to the directory of the application +before starting it, all template and auxiliary files should be found +easily there without editing mfile.tcl. Note however that this +directory will also become the default directory where »Makefile« will +be stored, unless you change a different location with »Save As...« + +As another option, the following has been contributed by Eric Weddington +on how to properly create a shortcut on the desktop: + +1. Extract the mfile.zip archive into your WinAVR +installation directory. This will automatically create a +subdirectory \mfile with all the needed files in this +subdirectory. + +2. Create a Shortcut on your Desktop. + +3. For the location of the item, select the program +wish84.exe which is located in \bin subdirectory of your +WinAVR installation directory. Add a space and then type +the absolute pathname of the program, mfile.tcl, which is +located in the mfile subdirectory of your WinAVR +installation directory. + +For example, if your WinAVR installation directory is at +C:\WinAVR, then the item will look like: +C:\WinAVR\bin\wish84.exe C:\WinAVR\mfile\mfile.tcl + +4. The name of the Shortcut should be: MFile + +5. When finished, you will have to go back and properly +select the Start Directory. Right-click the shortcut icon +on your Deskopt and select Properties. In the Start In edit +box, put in the mfile subdirectory of your WinAVR +installation directory. NOTE! This is essential if MFile is +to execute correctly as there are additional files that it +needs to find. + +For example, if your WinAVR installation directory is at +C:\WinAVR, then the Start directory will be: +C:\WinAVR\mfile + +Installation on Unix +-------------------- + +Extract the archive into an arbitrary subdirectory, like + +/usr/local/share/mfile + +If a different directory is chosen, edit the setting of »prefix« on +top of mfile.tcl to match the installation directory, or alternatively +use the environment variable MFILE_HOME to override the default +setting. + +If you'd like to use a different interpreter than +/usr/local/bin/tixwish, edit the #! setting in the first line. The +standard Tk wish interpreter is supported as well as the tix toolkit +one. + +If you prefer, create a symbolic link for convenience (so the +application can be found along your default $PATH setting), like + +ln -s /usr/local/share/mfile/mfile.tcl /usr/local/bin/mfile + +Remember to edit the file makefile_template to suite your needs (e. g. +default settings, adaptation to non-GNU make utilities). + + +Upgrading an Mfile installation on WinAVR +----------------------------------------- + +Starting with WinAVR 20040404, the WinAVR collection is shipping Mfile +pre-installed. (After all, the WinAVR users have once been the +primary reason to develop Mfile at all.) + +In order to upgrade the Mfile files supplied with WinAVR, extract the +archive into some directory, and copy all the files into + +\mfile + +That ought to be all that is to be done. + +---------------------------------------------------------------------- +Dresden, F.
