On https://trac.sagemath.org/ticket/32242 I propose adding the standalone GNU "info" reader as a new standard package.
In sage/interfaces/singular.py, we currently manually parse Singular's Info file to obtain docstrings for Singular's functions. This is not great: 1. We're maintaining an ad-hoc parser for a standard format that can already be read reliably by another tool that everyone has. 2. The manual parser needs to know the location of Singular's info file. This is a headache for packagers, because everyone needs to hard-code their own path, and it's one of the things preventing us from using a system copy of Singular. Using GNU Info alleviates the problem, because in essence we can just run "info singular" and count on the documentation being installed in the right place. 3. The manual parser is looking for Singular's info file relative to an environment variable named SINGULARPATH, which isn't used correctly at the moment (it's an upstream variable that we mangle in sage-env, but can be multi-valued). This is more of a boring technical problem, but also has to be solved before we can use a system copy of Singular. Using GNU Info means we don't care about the variable at all and can delete it. GNU Info (or its superproject, Texinfo) is already installed on most linux distributions and is available everywhere, although you may wind up building the SPKG on BSD. But ideally, the spkg-configure.m4 will find "info" in everyone's $PATH and this additional dependency will be a no-op. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
