<p>This time I was working on olibc. I rewritten Makefile and restrustured the project a bit.
|
||
I have added some macros to sys headers, so olibc is on path of beign able to compile itself.</p>
|
||
|
||
<p>Currently I am working on adding other useful headers. I think we can add POSIX headers
|
||
to it, so it will have implemented not only C11 specifications, but also some more
|
||
UNIX-related things.</p>

<p>Last week I wasn’t online for weekends, so decided to write devlog this week.
|
||
Also, last 2 weeks I was mostly working on one of my admin projects
|
||
(<a href="https://hextilde.xyz">hextilde.xyz</a>), so haven’t done anything in that period of time.</p>
|
||
|
||
<p>This week I was working on coreutils. It wasn’t maintained for a long time, so I decided to
|
||
add some utilities to it.</p>
|
||
|
||
<p>I have restructured it, rewrote cat and added some utilities - head and wc.</p>

<p>This 2 weeks I was working on deertree specifications. They are
|
||
avalible on <a href="https://gruos.org/deertree">https://gruos.org/deertree/</a>, but weren’t
|
||
published on git because I think that they are not done yet.</p>
|
||
|
||
<p>Also I was working on compiler. First several days I was trying lex/yacc and even implemented
|
||
basic syntax tree. But then I changed to python (I named this compiler pydtc), because I don’t
|
||
fully understand syntax trees yet, so I hope in python it will be a bit easier.</p>
|
||
|
||
<p>So far with python I made some progress and it can already output syntax tree for very basic code
|
||
and convert it to C or Assembler (yes, I added support for both).</p>

<p>This 2 weeks I spent developing new programming language, called DeerTree.
|
||
It is going to be combination of C, Rust and Go to make low-level development a bit simpler.</p>
|
||
|
||
<p>I have written some parts of specifications for language and standart library,
|
||
but I think it is not ready for publishing yet.</p>
|
||
|
||
<p>But I have already started implementing compiler using lex and yacc. It already has lexer and
|
||
basic parser implemented, right now I am working on syntax tree.</p>
|
||
|
||
<p>Also I have published txtutils. It has just grep for now.</p>

<p>This 2 weeks I spend implementing new yemu features. I implememented CMP ocpu instruction
|
||
and added very basic stack implementation and some instructions for it. I will need to
|
||
add more description about stack and stack manipulation instructions to ocpu specifications.</p>
|
||
|
||
<p>Also I started coding txtutils. I am planning it for text manipulation programs (grep, sed,
|
||
awk). Started to develop grep utility, it already can find text in input, but not supports
|
||
some “regex commands” that I would like it to support. Also I want to add support for
|
||
multiple files there.</p>

<p>This 2 weeks I was coding yemu. I added handling for flags, so now after any operation ZF and
|
||
NF flags changed to correct values. Also I added opcodes for CF manipulations, so carry flag
|
||
can be set and unset. Also I was fixing and detalizing specs, because I needed it to implement
|
||
other commands. I added logical instructions - AND, OR, NOT, XOR.</p>
|
||
|
||
<p>This week I was mostly researching about something that can be interesting, but don’t have
|

enough information for a project yet. It is pretty complicated sphere, so I don’t know when

I will do something interesting there.</p>

<p>Last week I found why title tag wasn’t working - I haven’t implemented one of cases, so it is
|

failing on them. I am still trying to make it working.</p>
|
||
|
||
<p>This week I started to make own forth implementation called orth. Currently it can do very little
|
||
amount of things: tokenize input, get numbers. Trying to implement token stack right now.</p>
|
||
|
||
<p>Also, I have received email from fosshost. So they accepted our application and requested details
|
||
about what VM we need. We decided to go with x86_64 CPU, 5G RAM and 50G disk.
|
||
I think everything should be fine.</p>
|
||
|
||
<p>I am a bit lazy last few weeks, but I guess it is fine and I will get back on track soon.</p>

<p>This 2 weeks were not very productive I think. I published libweb. I think it already can

support the most basic web 1.0 pages, because it has support of headers (h1, h2, …)

and paragraphs tags (p). This week I tryed to implement title tag but had troubles with it,

will publish it when it will be done…</p>

<p>I think this weeks were productive. Last week I have accessed initrd on orion and printed
|
||
tar archive files. Currently VFS is needed to be implemented and for that I need kmalloc.</p>
|
||
|
||
<p>Also several more functions were added to EGG E - set background color, drawing rectangles,
|
||
lines, circles and maybe some other ones. Currently I don’t know how it will be made into
|
||
real display server, but I hope that we will see.</p>
|
||
|
||
<p>I think the coolest project I was working this days is LibWeb. It is going to be library
|
||
where web things will be implemented. Currently I am working on HTML tokenizer and parser.
|
||
It already can tokenize and parse very simple page with head and body, but it is already
|
||
very cool, because i started it just several days ago. Also I would like to implement CSS
|
||
and maybe JavaScript (ECMAScript) there.</p>
|
||
|
||
<p>Also I thought about some other ideas - LibImage and LibJSON. I think after HTML it won’t
|
||
be very hard to parse them, and they could help us in future when we will be making more
|
||
GUI things.</p>
