@table @command
+@pindex redo
@item redo
Forcefully and sequentially build specified targets. This is the
main command you will explicitly use from the command line. If no
targets are given, then @file{all} target will be used by default.
+
+@pindex redo-ifchange
@item redo-ifchange
Rebuild specified targets if they are out-of-date and record them as
a dependency for the currently run target. This is the main command
you will use in @file{.do} files.
+
+@pindex redo-ifcreate
@item redo-ifcreate
Record the non-existent file dependency for the currently run
target. Target will be rebuilt if any of the given files appear. Can
the given targets, but ordinary @command{redo} is not: it builds
specified targets sequentially and stops when error happens.
+@cindex tracing
@option{-x} option can be used to enable tracing (@code{set -x}) of the
currently run shell script @file{.do} file. @option{-xx} option enables
tracing for all invoked @file{.do} files further.
+@cindex parallel build
With @option{-j} option you can enable parallel builds, probably with an
infinite number of workers (@code{=0}). Also you can set
@env{$REDO_JOBS} to automatically apply that setting globally.
Read about @ref{Logs, log storage capabilities}.
+@cindex debug
+@vindex REDO_LOG_PID
+@vindex REDO_DEBUG
@option{-log-pid} (@env{$REDO_LOG_PID=1}) can be used to prefix job's
@code{stderr} with the PID, that could be useful during parallel builds.
@option{-d} (@env{$REDO_DEBUG=1}) enables debug messages.
+@cindex progress
+@vindex REDO_NO_PROGRESS
+@vindex REDO_NO_STATUS
+@vindex NO_COLOR
@option{-no-progress} (@env{$REDO_NO_PROGRESS=1}) and
@option{-no-status} (@env{$REDO_NO_STATUS=1}) disable statusline and
progress display. @env{$NO_COLOR=1} disables progress/debug messages
colouring.
+@cindex fsync
+@vindex REDO_NO_SYNC
By default all build commands use @code{fsync} to assure data is reached
the disk. You can disable its usage with @env{$REDO_NO_SYNC=1}
environment variable, for speeding up the build process.
+@vindex REDO_STOP_IF_MODIFIED
If redo sees some target modified externally, then by default it warns
user about that, does not build that target, but continues the build
process further. That is convenient in most cases: you can build your
There are other commands that could be found in other implementations too:
@table @command
+@pindex redo-always
@item redo-always
Record current target as an always-do dependency. By definition it
should be always build. @command{goredo} tries to build it once per
@strong{run}.
+
+@pindex redo-stamp
@item redo-stamp
Record "stamp" dependency. It reads @code{stdin} and stores its hash
in the dependency database. It is not used anyhow, it is dummy. Read
about @ref{Stamping, stamping} in the FAQ. It is left only for
compatibility with some other implementations.
+
+@pindex redo-targets
+@pindex redo-ood
@item redo-targets, redo-ood
Show all known targets, possibly limited by specified directories.
@command{redo-ood} shows only the out-of-date ones.
+
+@pindex redo-sources
@item redo-sources
Recursively show all source files the given targets depend on.
+
+@pindex redo-affects
@item redo-affects
It is not in other distributions, but it is some kind of opposite of
@command{redo-sources} -- shows the targets that will be affected by
And there are some maintenance and debug commands:
@table @command
+@pindex redo-cleanup
@item redo-cleanup
Removes either temporary (@option{tmp}), log files (@option{log}),
- or everything related to @command{goredo} (@option{full}).
+ lock files (@option{lock}), or everything related to @command{goredo}
+ (@option{full}).
+@pindex redo-whichdo
@item redo-whichdo
Display @file{.do} search paths for specified target (similar to
@command{apenwarr/redo}):
../default.do
@end example
+@pindex redo-dot
@item redo-dot
Dependency
@url{https://en.wikipedia.org/wiki/DOT_(graph_description_language), DOT}
$ dot -Tpng whatever.dot > whatever.png # possibly add -Gsplines=ortho
@end example
+@pindex redo-depfix
@item redo-depfix
When you copy your worktree to different place, then copied files
ctime will change. And because recorded dependency information
