This morning I was thinking that SCons doesn't have any
kind of interactive mode that is tied to modern user needs.
Here is how it looks now:
$ scons --interact
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons>>> ?
build [TARGETS] Build the specified TARGETS and their dependencies.
'b' is a synonym.
clean [TARGETS] Clean (remove) the specified TARGETS and their
dependencies. 'c' is a synonym.
exit Exit SCons interactive mode.
help [COMMAND] Prints help for the specified COMMAND. 'h' and
'?' are synonyms.
shell [COMMANDLINE] Execute COMMANDLINE in a subshell. 'sh' and '!'
are synonyms.
version Prints SCons version information.
scons>>>
scons>>> help b
scons>>> help build
build [TARGETS] Build the specified TARGETS and their
dependencies. 'b' is a synonym.
Note that command help is not helpful at all.
How it could look like:
$ scons --interact
scons: Reading SConscript files ...
scons: no SConscript files found.
scons: SCons 2.5.0 interactive mode.
scons: Type "help" to learn more or "exit" to quit.
scons>>> help
build [TARGETS] Build TARGETS and their dependencies.
clean [TARGETS] Clean (remove) TARGETS and their dependencies.
exit Exit interactive mode.
help [COMMAND] Print help for the specified COMMAND. '?'
is synonym.
shell [COMMANDLINE] Execute COMMANDLINE in a subshell. '!' is synonym.
scons>>>
Note that 'b', 'c' and 'h' are not there. It is better to choose command
using longest match.
What doesn't work?
1. --interactive without a SConstruct.
$ scons --interact
scons: *** No SConstruct file found.
File "../engine/SCons/Script/Main.py", line 912, in _main
What is missing?
1. target list
2. builder tree
3. help on specific builders and SCons commands
4. pager for all the above
