### BUGS
|
|
- (read-file "nonexisting/file.csv") shows only "could not open file" - should print filename
|
|
- better error reporting..for example ls_dir on non existing dir should prind `pwd` dir
|
|
|
|
|
|
### TODO
|
|
- add debug support, at least call stack
|
|
- multiline editing (kilo editor)
|
|
- execute system command should capture stderr
|
|
- add some mem stats to benchmark
|
|
- create pastebin like web using ml
|
|
#### Code
|
|
- documentation
|
|
- rename constants in ml_profiler.h
|
|
- replace to_string macro in ml.cpp
|
|
- add url of source/inspiration to clib/*.cpp
|
|
- add instrumentation (time, nr of evals, num of atoms, debug info, debug environment etc)
|
|
#### Language
|
|
- support for "t" symbol as a true
|
|
- support for exceptions
|
|
- string functions
|
|
- compare - needed for sorting, cmp ignore case
|
|
- regexp functions
|
|
- date support
|
|
- decode-universal-time
|
|
- env functions
|
|
- get-env, set-env; set-env cannot be implemented in stdlib.lsp, because popen is in fact subshell
|
|
- add include-stdlib function for other libs in stdlib dir (during startup stdlib.lsp is loaded only)
|
|
- syntax highlighting do VS Code
|
|
|
|
#### Performance
|
|
- define is one of most frequent callee, when in scope with very few vars, lookup sequentially
|
|
- first, second are often called -> implement in c++
|
|
- push_back - repeatedly without reserving size
|
|
- range - with for(int i...) and reserving result size can be 3times faster on (range 1 10000)
|
|
- mini_sprintf - unnecesary copying between vector and list
|
|
- (do, scope ..) repeatedly assign to acc
|
|
|
|
#### Compile
|
|
```
|
|
mkdir -p build
|
|
gcc -std=c99 -c -O2 -o linenoise.o clib/linenoise.c
|
|
c++ -c -O2 -I/usr/local/opt/openssl/include -Iclib --std=c++17 ml.cpp ml_io.cpp ml_date.cpp ml_string.cpp ml_util.cpp ml_profiler.cpp clib/json11.cpp clib/csvparser.cpp clib/sslclient.cpp clib/printf.cpp
|
|
// on linux c++ -o build/ml -O2 -L/usr/local/lib -L/usr/local/opt/openssl/lib -lm -lstdc++ -lcrypto -lssl *.o
|
|
c++ -o build/ml -O2 -L/usr/local/lib -L/usr/local/opt/openssl/lib -lm -lstdc++ -lcrypto -lssl -Wl,-stack_size -Wl,0x1000000 *.o
|
|
```
|
|
// or cmake
|
|
|
|
#### Install
|
|
```
|
|
cp build/ml /usr/local/bin/ml
|
|
cp stdlib/*.lsp /usr/local/var/mlisp/
|
|
```
|
|
or
|
|
```
|
|
utils/local_install.sh
|
|
```
|
|
|
|
|
|
### Example of use
|
|
```
|
|
ml -f tests/test.lsp
|
|
```
