#4 | 3183 | Craig Mcpheeters | Integration of my jam mainline branch into my work branch. | ||
#3 | 785 | Craig Mcpheeters |
Integration from //guest/craig_mcpheeters/jam/src/... This work area now contains both the Alias|Wavefront changes, and the latest integrations from the mainline. There are some changes in this area which shouldn't be merged back into the mainline. As I merge this branch back into my jam/src/... branch, I'll leave out a few of the changes. |

#2 | 782 | Craig Mcpheeters |
Initial return of the Alias|Wavefront mods to jam 2.2. I made a stab at a configuration system - see the file Jamfile.config. Most of the mods are now enclosed within #ifdef blocks, which kind of pollutes the code, but may make it easier to accept or reject some of these changes. Some of these #ifdefs could disappear completely if they are accepted into the mainline This return implements the following extensions: * header cache * dynamic command block size, allowing for *large* commands * slightly improved warnings and errors * serial output from jam - nice when working with multiple jobs * an extension to variable modifiers: $(>:/) and $(>:\\) * ability to ignore header dependencies for a build (jam -p) * new debug level, -d+10, which outputs the dependency graph * added no-care support to internal nodes. if they fail, dependents are built anyway * time stamps on output * a few minor output modifications * a fix for nt batch file names conflicing when more than one jam runs at a time Each of the above can be enabled/disabled on the command line. For example, to turn on the HeaderCache code: jam -sHeaderCache=1 that is, build jam first, then use that jam to build a new one with the options you want. Some of these changes may have been made in the mainline already, my next step will be to integrate the mainline changes into these ones This return isn't yet ready for prime-time |

Branch of my jam/src/... area. This new area establishes the integration base for the copy of Jam which has all the changes. |
