applies to the variable name, not its value!
Remove the set of examples that were recently added that failed to
explain why some worked and some didn't.
Add a not to the compatability section about the change in .for loop
substitution post 5.0.
Add a BUGS section.
XXX the BUGS section needs more entries :-)
argument to be exclosed in (...).
'.if exists()' is parsed as '.ifdef exists()' and the ')' must not be
left over at the end.
I have no idea why any of my recent changes have affected this.
But pkgsrc/mk/compiler/gcc.mk (line 488) does .if exists(${FCPATH})
even though FCPATH is only set when the file exists.
Saves having to malloc/free a fixed size structure.
Buf_Init() now takes ptr to Buffer to initialiase.
Change Buf_Destroy() to return ptr to string when not freed.
Remove large number of casts to (Byte) and (Byte *) - 'Byte' is 'char' here.
Buf_AddByte[s] guarantees that the data is 0 termininated, so never add '\0'.
Keep 'count' not 'left' and 'inPtr', code is simplier with only one update.
Fix fallou, no functional change.
variable references - eg ${.TARGET} since that can't be expanded earlier.
Also the variable gets re-expanded before modifiers are applied.
All this means that we do need to let :U expand variables and must not
just escape $.
as well as ':' and '}' or ')'.
The parameters have just been expanded (and will be expanded again) later
so don't need expanding as part of the :U process.
Seems to fix pkgsrc breakage at line 34 of bsd.pkginstall.mk doing:
.for i in ${PKG_USERS}
_PKG_VARS.pkginstall+= PKG_UID.${u} PKG_GECOS.${u} PKG_HOME.${u} PKG_SHELL.${u}
.endfor
when PKG_USERS = ${AVAHI_USER}:${AVAHI_GROUP}::Avahi\ user:/nonexistent
(set at line 41 of the ahavi Makefile)
I really dont think the above has the desired effect!
Ignore '=' and ' ' inside {} and () when looking for an assignment operator.
Also require the operator be immediately after any whitespace.
XXX mismatched (){} in variable modifiers will not DTRT.
Note that any of "${}()" in variable names will be griefsome!
Remove the example of using ::= to apply a modifier to a .for loop
variable as that is no longer necessary.
Remember to change the date :-)
Instead of doing a full substitution giving plain text, just replace the
variable part with something that will expand to the required text - leaving
any modifiers for the later evaluation of the input line.
This stops .for being used as an 'eval' (previously you could generate .if etc)
and also means it is still a variable expansion - which some other parts need
to work in the expected fashion.
parts of make that try to scan through variable expansions.
(given the make syntax that is all rather doomed anyway!)
Move the check for $\0 to a place where it will be detected - otherwise
the parser will run off the input buffer!
Use for the .for variables and substution items - changing the latter from
make's all conquering lst.lib functions.
Being able to index everything makes the code simpler.
No functional changes intended.
Replace Buf_Discard() with Buf_Empty() since the former might leave the
'outPtr != buffer' and the only caller wanted all the data discared.
Remove 'outPtr' now that it always equals 'buffer'.
The assumption about Buf_GetAll()is now guaranteed by design.
