- Reduce the use of global variables by packing all them in a struct
- Redesign the autocompletion method for r_line
- Not yet finished, but so much refactoring out there :)
- Using the singleton format (r_xxx_instance)
- APIs has been cleaned up
- Some bugs fixed
- Syntax fixes

* 'Supr' key not handled properly
|
|
* Optionally link against libreadline (NO PLZ)
|
|
* Remove all label-related stuff (OW YEAH)
|
|
* Make dietline fully compatible with readline (WHY?)
|
|
* Define API outside as r_line_... in ../include/
|

Design:
|
|
=======
|
|
|
|
r_line API
|
|
- N-level commands autocompletion
|
|
- autocompletion methods:
|
|
- from an array of strings
|
|
- this array of strings can be generated by a callback
|
|
that identifies the word number
|
|
- we can just assign a function pointer to the tree of keywords
|
|
- autocompletion function is defined by first word and Nword.
|
|
- this is:
|
|
ls [file]
|
|
ls -[flags] [file]
|
|
x @ [num]
|
|
/<tab> files
|
|
if word_count==0 && word[0]=='/':
|
|
return autocomplete_filename
|
|
|
|
RLineCompletion* level0 = {
|
|
{ },
|
|
{},
|
|
NULL
|
|
};
|
|
|
|
typedef int (*RLineCompletion)(RLine *line);
|
|
|
|
#define R_LINE_NCOMP 8
|
|
typedef struct r_line_t {
|
|
char *prompt;
|
|
int word;
|
|
RLineCompletion *root;
|
|
RLineCompletion *child[R_LINE_NCOMP]; /* 8 nested levels of completion */
|
|
} RLine;
|
|
|
|
r_line_instance.root (&r_line_instance);
|
|
r_line_instance.child[0] ();
|
|
|
|
level0 completion
|
|
level1 completion is defined by level0 word
|
|
we need a stack of completion methods defined by each completion method
|
|
- this can be done by a statik array of funptr
|
