A modular front-end for interacting with external debuggers
A modular, extensible GNU Emacs front-end for interacting with external debuggers. Quick start: https://github.com/realgud/realgud/ See URL `https://github.com/realgud/realgud/wiki/Features' for features, and URL `https://github.com/realgud/realgud/wiki/Debuggers-Supported' for debuggers we can handle. Once upon a time in an Emacs far far away and a programming-style deservedly banished, there was a monolithic Cathederal-like debugger front-end called gud. This interfaced with a number of debuggers, many now dead.[1] Is there anyone still alive that remembers sdb from UNIX/32V circa 1980? This isn't that. Here we make use of more modern programming practices, more numerous and smaller files, unit tests, and better use of Emacs primitives, e.g. buffer marks, buffer-local variables, structures, rings, hash tables. Although there is still much to be desired, this code is more scalable and suitable as a common base for an Emacs front-end to modern debuggers. Oh, and because global variables are largely banned, we can support several simultaneous debug sessions. RealGUD supports many external debuggers. See URL `https://github.com/realgud/realgud/wiki/Debuggers-Supported' for a list. However, if you don't see your favorite debugger, see URL `https://github.com/realgud/realgud/wiki/How-to-add-a-new-debugger/' for how you can add your own. The debugger is run out of a comint process buffer, or you can use a `realgud-track-mode' inside an existing comint shell, or eshell buffer. To install you will need a couple of other Emacs packages installed. If you install via melpa (`package-install') or `el-get', these will be pulled in automatically. See the installation instructions URL `https://github.com/realgud/realgud/wiki/How-to-Install' for all the ways to to install and more details on installation. [1] Four or more years in, as of 2018 realgud sports a number of old debuggers too. However we *mark* them as such, and move them out of the main code base. See for example: https://github.com/realgud/realgud-old-debuggers. So that's another difference: this code better *maintained*.
