| 1 | Write Texinfo documentation for grep.  The manual page would be a good | 
|---|
| 2 | place to start, but Info documents are also supposed to contain a | 
|---|
| 3 | tutorial and examples. | 
|---|
| 4 |  | 
|---|
| 5 | Fix the DFA matcher to never use exponential space.  (Fortunately, these | 
|---|
| 6 | cases are rare.) | 
|---|
| 7 |  | 
|---|
| 8 | Improve the performance of the regex backtracking matcher.  This matcher | 
|---|
| 9 | is agonizingly slow, and is responsible for grep sometimes being slower | 
|---|
| 10 | than Unix grep when backreferences are used. | 
|---|
| 11 |  | 
|---|
| 12 | Provide support for the Posix [= =] and [. .] constructs.  This is | 
|---|
| 13 | difficult because it requires locale-dependent details of the character | 
|---|
| 14 | set and collating sequence, but Posix does not standardize any method | 
|---|
| 15 | for accessing this information! | 
|---|

| 19 | Some test in tests/spencer2.tests should have failed !!! | 
|---|
| 20 | Need to filter out some bugs in dfa.[ch]/regex.[ch]. |

| 22 | Threads for grep ? | 
|---|
| 23 |  | 
|---|
| 24 | Grep does 32 bits arithmetic, it needs to move to 64. | 
|---|
| 25 |  | 
|---|
| 26 | Clean up, to many #ifdef's !! | 
|---|
| 27 |  | 
|---|
| 28 | Check some new Algorithms for matching, talk to Karl Berry and Nelson. | 
|---|
| 29 | Sunday's "Quick Search" Algorithm (CACM 33, 8 August 1990 pp. 132-142) | 
|---|
| 30 | claim that his algo. is faster then Boyer-More ???? | 
|---|
| 31 | Worth Checking. | 
|---|
| 32 |  | 
|---|
| 33 | Take a look at cgrep (Context grep) seems like nice work. | 
|---|
| 34 | Take a look at sgrep (Struct grep). | 
|---|
| 35 | Take a look at agrep (Approximate grep), from glimpse. | 
|---|
| 36 | Can we merge ? | 
|---|
| 37 |  |

| 38 | POSIX Compliance see p10003.x | 
|---|
| 39 |  | 
|---|
| 40 | Moving away from GNU regex API for POSIX regex API. | 
|---|
| 41 |  | 
|---|
| 42 | Better and faster !! |
